Best prediction markets, ranked

Every platform we have scored is ranked here, and they are not variations on one another: US exchanges named on the federal register, regulated brokers, offshore on-chain order books and a play-money market where nothing is at stake. Below is how they rank on our nine-criterion model, with availability shown for your region.

Every score on this page is preliminary, and the badge next to it says so. We have rated the criteria that a fee schedule, a regulator’s register, a rulebook and a company’s own documentation can settle — costs, regulation, market breadth, deposits and withdrawals, promotions, and how a venue resolves a market and handles a dispute. Interface quality and support response time are unrated on every platform we cover, because rating them means opening an account and contacting a support desk, and nobody here has. Liquidity is unrated on the platforms ranked here: we hold no licence to redistribute the order-book and volume data that would measure it, and where a liquidity rating does appear elsewhere on this site it says in its own breakdown that it is an inference from a book we looked at, not a measurement we took.

Ranked platforms

  1. Kalshi

    7.7/10preliminary

    Best verifiable regulatory position

    Kalshi is a CFTC-designated contract market with identity verification and fiat funding options. Its fee schedule is now linked in our source log, including the general price-dependent formula and series exceptions. Check both country eligibility and the chosen contract before opening a position.

    Regulated✅ Available

    KalshiEX is a CFTC-designated contract market and its Member Agreement names no US state as restricted. State court orders block some contract categories in Nevada, Washington and Michigan; elsewhere its contracts are available. Kalshi is in litigation with about 20 states, so this can change quickly.

  2. OG

    7.1/10preliminary
    Regulated✅ Available

    Help centre: “currently available in all U.S. states”, though some event contracts may be unavailable in some states (not named). App Store: “Available in all 50 US states”. New York has separate funding and portfolio articles.

  6. Crypto.com Prediction Markets

    5.8/10preliminary
    Regulated✅ Available

    Prediction Trading (and Sports Event Trading) is a CFTC-regulated feature of the Crypto.com App, offered through Crypto.com | Derivatives North America. The help centre says it is available in the US only.

  7. Alpha Arcade

    5.1/10preliminary
    Crypto✅ Available

    Not on Alpha Arcade’s list of restricted jurisdictions. Absence from the list does not by itself establish that an individual may use the platform.

  8. PredictIt

    3.9/10preliminary
    Regulated✅ Available

    The Terms and Conditions limit participation to people aged 18 or older who are U.S. Persons. They name no US state as excluded. PredictIt runs under CFTC no-action relief.

  9. Manifold Markets

    3.7/10preliminary

    Only if you want no money at stake

    Play money by design: Manifold states its currency “cannot be converted to cash”, and every user starts with M1000 free. That makes it the cheapest way to learn how contract pricing behaves, and it is why it ranks last here — a balance you cannot withdraw scores badly on deposits and withdrawals, and no licence backs it. Its documented offers are the fairest in the pool, with no deposit and no wagering condition, and worth nothing in money terms. Read the score as a measure of the instrument, not of the community.

    Play money✅ Available

    Play-money mana trading is open to users 13+ (minors need a guardian). Outside the listed states, US residents aged 18+ can also enter prize drawings.

  11. Polymarket US

    7.3/10preliminary
    Regulated⚠️ Restrictions

    QCX LLC publishes no list of eligible or excluded states. A Nevada court granted a preliminary injunction against QCX LLC d/b/a Polymarket US on 29 May 2026 (Nevada Gaming Control Board). Missouri's Attorney General has sent a cease-and-desist over sports contracts, and New York has announced a lawsuit; neither state is marked closed because the operator has not said it geoblocks them.

    Read review

  12. Polymarket

    6.9/10preliminary

    Widest verified market breadth, if it will take you

    The broadest published category list of the three — 11 categories in its own fee schedule, covering every category we track — and a fee schedule that charges makers nothing and takers 0.04 to 0.07 scaled by price, so 100 crypto shares at 50¢ incur a $1.75 fee before rebates and geopolitics is free. The catch is access: Polymarket’s own documentation puts the United States, United Kingdom, Germany and Brazil among jurisdictions where you may close positions but not open them. This record covers the offshore book, not the separately designated Polymarket US entity.

    Crypto⚠️ Restrictions

    The international polymarket.com site is closed to US residents: no deposits and no trades. The help centre lists the US as blocked and the API docs list it as close-only. US residents are sent to the separate Polymarket US app, run by QCX LLC (a CFTC DCM). Polymarket US state-level eligibility was not verified because its ToS page loads its text client-side.

  13. ProphetX

    6.0/10preliminary
    Regulated⚠️ Restrictions

    ProphetX says it is “available nationwide” but publishes no excluded-state list; its help centre says access “is restricted from certain locations and IP addresses”. Connecticut reportedly ordered it to stop offering sports contracts to residents (September 2026); the order could not be read on the regulator’s site.

  14. Underdog Predictions

    5.3/10preliminary
    Regulated⚠️ Restrictions

    Only in states where Underdog Predict operates: "Must be 18+ and present in a state where Underdog Predict operates". The operator's state list (help centre) could not be read, so other states are unconfirmed.

    Listed in the Terms (updated 24 Jan 2025) among countries whose residents may not use Real-Money Services. Play-money (Ooms) markets stay open, and the app tells users from Restricted Jurisdictions they can still bet play money.

1. Kalshi

CFTC-regulated event contract exchange

7.7Prelim

Kalshi is a CFTC-designated contract market with identity verification and fiat funding options. Its fee schedule is now linked in our source log, including the general price-dependent formula and series exceptions. Check both country eligibility and the chosen contract before opening a position.

Strengths

  • CFTC-designated contract market
  • Fiat deposits and withdrawals, no wallet needed
  • Default maker fee is zero, with charged series exceptions
  • Mobile apps on both platforms

Watch out

  • Country restrictions and account approval apply to international users
  • Narrower market selection than on-chain venues
  • KYC required before you can trade
  • Trading fees vary by contract price and series

4. FanDuel Predicts

FanDuel event contracts listed by CME Group and Crypto.com

6.2Prelim

Strengths

  • Contracts are listed and settled by CME, an established derivatives exchange, under a published rulebook chapter
  • Per-product contingencies are concrete and state what happens to an open position
  • The arbitration agreement expressly preserves CFTC reparations under Section 14
  • Exchange documents are public through CFTC filings and readable without an account

Watch out

  • For every sports, entertainment and awards contract, CME’s certified table gives the settlement source as “Fanduel” — the firm distributing the contract
  • No document describes how that data is produced or what happens if it is wrong
  • FanDuel’s public Predicts pages never say who determines outcomes, never cite the governing chapter and never mention the source
  • A catch-all lets the exchange set a settlement price in “sole discretion”
  • One sports contingency changed from cancelling positions to liquidating them at fair value while keeping the same label
  • No determination log is required or published anywhere

5. Interactive Brokers ForecastTrader

Forecast contracts listed on ForecastEx, a CFTC-designated contract market

5.9Prelim

Strengths

  • A published specification for every contract — we checked roughly 11,470 live instruments and found none missing
  • The only venue we cover with a real, dated, public record of contested settlements: 439 notices including eight data overrides
  • A separate disciplinary log, which includes a filing against Interactive Brokers itself
  • Interest paid on open position value, which no other venue here offers
  • Contract terms settle the revision question explicitly rather than leaving it to be argued

Watch out

  • The exchange is a wholly owned subsidiary of the broker’s parent, so the broker owns the venue that decides
  • Determinations are “final and not subject to review”
  • The exchange’s own committee decides whether a dispute may go to arbitration, and that decision is final too
  • Binary contracts have been settled non-binary at 50/50, which the customer-facing FAQ does not prepare anyone for
  • Rule 415 assigns a data-error decision to a body the rulebook never defines
  • Economic and political contracts only — not a sports venue

6. Crypto.com Prediction Markets

USD-settled event contracts in the Crypto.com app, listed by CDNA

5.8Prelim

Strengths

  • Contract specifications are filed with the CFTC, so they need no account to read and cannot be quietly edited
  • The elections contract names fourteen source agencies individually rather than gesturing at “official sources”
  • The delay contingency is written out: settlement waits until the source releases the outcome
  • Sits inside an app many US readers already have, with no separate account to open

Watch out

  • We could not locate CDNA on the CFTC’s own Designated Contract Market register, so no licence is claimed on this page
  • The CDNA rulebook, which the filings defer to for jurisdiction and enforcement, could not be retrieved
  • The fourteen source agencies apply “as determined by the Exchange”, so the authoritative outlet is chosen after the fact
  • No public record of past determinations was found
  • Available in the United States only

8. PredictIt

Political event contracts run under CFTC no-action relief

3.9Prelim

Strengths

  • Every market’s settlement rules are readable through a public API with no account — better disclosure than several regulated venues
  • The longest continuous price history in US political prediction markets
  • Settlement is targeted at under 48 hours, and the venue says so rather than leaving it open
  • Political questions listed here that designated exchanges do not offer

Watch out

  • No regulator at all — its own terms say it is not regulated by the CFTC “or any other regulatory authority”
  • The operator writes the rules and judges the outcomes, and its decision is stated to be “final”
  • Accepting the terms waives your right to seek other remedies, with disputes sent to AAA arbitration
  • The terms permit cancelling an account “for any reason”, expressly including because you began a dispute
  • A per-participant cap tied to the federal contribution limit, so position size is constrained by rule
  • The CFTC no-action letters say nothing about determination or recourse, despite being cited as if they did

Strengths

  • No money at risk — play currency only
  • Anyone can create a market
  • Open API and public leaderboard
  • No KYC and no deposit needed

Watch out

6.9Prelim

The broadest published category list of the three — 11 categories in its own fee schedule, covering every category we track — and a fee schedule that charges makers nothing and takers 0.04 to 0.07 scaled by price, so 100 crypto shares at 50¢ incur a $1.75 fee before rebates and geopolitics is free. The catch is access: Polymarket’s own documentation puts the United States, United Kingdom, Germany and Brazil among jurisdictions where you may close positions but not open them. This record covers the offshore book, not the separately designated Polymarket US entity.

Strengths

  • Deepest liquidity in the category on major markets
  • Fastest listing of new events
  • No maker trading fees under the published schedule
  • Public API with full order book access

Watch out

  • Requires a wallet and USDC — no fiat rails
  • International product has country restrictions; Polymarket US is separate

  • An unresolvable market is voided with stakes returned rather than settled on a guess
  • 208,358 resolved events are readable over the public API, so the settlement record is inspectable at scale

Watch out

  • The terms state twice that Futuur has “sole discretion” over determinations and that they are “final and binding”
  • No dispute window, bond or escalation anywhere; the route offered is email
  • The API carries a first-class “reversed” status, so undoing a settlement is a designed capability
  • The terms page carries two copies naming different companies — Anjouan and Curaçao — under two governing laws
  • Play-money and real-money markets run side by side and must never be read as one book
  • Custody is with the operator; the duplicated terms leave the contracting entity unresolved

Permissionless prediction markets on Solana and Eclipse, with very thin books

1.7Prelim

Strengths

  • Trading mechanics are visible in the application itself
  • The venue states its own scope: permissionless prediction markets on Solana and Eclipse
  • Featured markets display their own liquidity figures, so the depth is visible before you connect
  • Runs on Solana and Eclipse, so settlement and balances are on a public chain rather than an operator’s ledger
  • No terms means no clause asking you to waive recourse — thin comfort, but several venues here do ask

Watch out

  • Nothing is published about how markets resolve: eleven likely paths 404 and six documentation subdomains do not resolve
  • Market content sits behind Connect Wallet, so per-market rules cannot be read before connecting
  • No terms, no privacy policy and no named operator
  • Featured markets showed $38 and $503 of liquidity — at that depth a position of any size is the market
  • Third-party descriptions of an oracle are uncorroborated by anything the venue publishes, so they are not used here

Strengths

  • Prediction markets on politics, economics and crypto alongside a deep sportsbook
  • Deposits and withdrawals on 23 networks in 50+ cryptocurrencies, from a few cents
  • Smart-contract audits by CertiK and Pessimistic; bonus terms published in full

Watch out

  • No identity checks (“No KYC”): fewer protections if an account or funds are disputed
  • Offshore gambling licence only — no financial or derivatives regulator oversees it
  • Closed to the US and about 25 other countries; illegal to use in many others
  • About 7% margin in sampled sports odds; prediction-market fees are not published
  • A deposit must be wagered before it can be withdrawn; sports wins capped at $5,000

On-chain binary markets on BNB Chain; closed to the US, the UK and all of the EU

Strengths

  • The widest category set of any venue added to this site in September, including hourly crypto markets
  • Books were genuinely two-sided across four categories at once when we read them
  • Third in the category by reported volume, behind only Kalshi and Polymarket
  • Publishes concrete dispute terms — a window, a stake formula and the consequence of losing
  • Names its operator in its terms of use

Watch out

  • Closed to the United States, the United Kingdom and all of the European Union
  • The primary resolver is “Opinion AI”, with no account of its inputs, model or sources
  • The review step is written with no actor: who performs it is never identified
  • Whether the team can resolve or override a market itself is not addressed anywhere
  • Only one dispute is permitted per resolution, so the first challenger spends the market’s single appeal

Strengths

  • Non-custodial: the venue never holds your balance
  • Zero maker fee, so posting liquidity costs only the spread you offer
  • Yield paid on USDT collateral while it sits against an open position — unique among the venues we cover
  • Six of the seven categories we track, the widest verified breadth of any venue we built from primary sources
  • Names its operating entity, which most on-chain venues do not

Watch out

  • Its own documentation describes two incompatible resolution mechanisms, both live on the same day
  • The developer page for the deployed oracle states “No bonding or dispute mechanism (simplified trust model)”
  • Admins can flag questions for emergency resolution, documented in developer pages rather than in the user terms
  • A role holder can settle Chainlink market rounds manually
  • No licence, no regulator, and no stated jurisdiction of incorporation

28. Trueo

Prediction markets on Base where open positions earn yield; closed to the US and Canada

5.2Prelim

Strengths

  • A permissionless optimistic oracle: anyone may propose an outcome by posting a bond, opening a 12-hour challenge window
  • Four named escalation stages ending with 11 randomly selected attesters
  • Constrains its own privileged body — all Oracle Council decisions may be permissionlessly challenged
  • No admin override, emergency power or discretion clause attaches to market outcomes anywhere in the documentation
  • Names its operator and publishes a full restricted-territories list with “We do not make exceptions”

Watch out

  • None of the design is evidenced in operation: there is no public dispute record
  • The final escalation is gated at 250,000 liquid TRUE, putting the last word with large holders
  • Market creation is still restricted to Oracle Council members in the genesis phase
  • The sources a dispute is judged against are not fixed — alternatives may be used
  • No licence or regulator; Samoa incorporation carries no consumer protection a reader could invoke

29. Myriad Markets

On-chain prediction markets settled in USD1 on BNB Smart Chain, and USDC.e on Abstract

5.0Prelim

Strengths

  • A three-dollar minimum, among the lowest barriers to entry we list
  • Zero maker fee
  • Per-market rules are published, so you can read what a contract turns on before trading
  • Settlement in USD1 or USDC.e, across crypto, politics, economy and sports

Watch out

  • The entire documented settlement process is one sentence: the team resolves
  • No oracle, no challenge window, no bond and no escalation anywhere in nineteen documentation pages
  • The only route offered to anyone disputing a settlement is a support ticket to the party that made it
  • The deployed contract carries an admin function that writes outcomes directly without calling an oracle
  • Myriad’s own commissioned audit says role holders have “control over which side wins”
  • The terms of use disclose no such role and reserve no such discretion

4.5Prelim

Strengths

  • Every YES + NO pair is fully collateralised by $1.00 USDC, so the money to pay the winner is locked at creation
  • Names its operator: Street Chow Inc., a Panamanian company, in terms dated 19 June 2026
  • Full market criteria are served to an unauthenticated API request
  • Publishes its refund policy plainly, which several venues in this pool do not

Watch out

  • The CFTC register entry reads Pending, not Designated — an application confers nothing
  • Settlement is centralised: Pyth resolves most markets, the Limitless team resolves the rest
  • No challenge window, no bond and no escalation; the documented remedy is an email
  • A misresolved market refunds only your stake, while the wrong side keeps its winnings
  • No licence or registration stated anywhere in its own documentation

39. Hyperliquid

Perpetuals venue whose HIP-4 outcome markets are fully collateralised binary contracts

3.6Prelim

Strengths

  • Question templates are voted on by validators before any market instantiates them
  • Ambiguity is pre-specified in the template text — draws, no contests, unlisted winners and missed deadlines all resolve to a stated value
  • The full settlement record is public and enumerable with no wallet
  • Contracts are fully collateralised and settle within a fixed range

Watch out

  • No dispute mechanism of any kind: a search of the whole documentation for dispute, challenge, bond, appeal and arbitration returns nothing
  • A single staked deployer key settles the market by submitting a fraction
  • The only page specifying who settles a deployer-registered market is subtitled “Testnet-only”, while mainnet markets are live
  • Template settlements must send an empty details field, so newer markets publish a number with no stated reasoning
  • The documented scope is one recurring BTC binary; multi-outcome markets are not in the initial release
  • No licence, operator, jurisdiction or age requirement stated; /terms returned HTTP 403

Prediction markets on Solana; no terms or documentation published

2.6Prelim

Strengths

  • Crypto markets resolve on a 15-minute TWAP with Pyth primary and Switchboard as a named fallback — manipulation-resistant by design
  • Real-world events require a 2-of-3 operator multisig rather than a single key
  • Publishes terms at all, which several venues in this cohort do not
  • Documents a 24-to-48-hour flagging route for incorrect resolutions

Watch out

  • The terms grant no right to flag: resolution criteria are “final and binding” and you waive claims over data sources, delays and voiding
  • Space “may cancel or void a Market at any time” and may extend the resolution period at sole discretion
  • It reserves the right to modify the underlying smart contracts at any time, which sits above the TWAP design
  • The AI validation step is undescribed — no model, inputs or evidence standard
  • The site carried no link to terms, privacy, legal, docs, about or FAQ, and /terms returned HTTP 500

How to choose

Start with whether the platform will take you at all — that is a harder question here than in most categories, and the availability badge on each entry answers it before anything else does. Then look at what you would be trading against: a designated contract market, an offshore order book, or play money. Those are three different propositions and no single ranking collapses them.

Compare costs using the same number of contracts and the same entry price. Kalshi and Polymarket publish price-dependent formulas; a percentage without its calculation basis can mislead. Manifold’s play-money markets serve a different purpose and should not be presented as a cash alternative.

The ordering below follows the Editor Score, and the Editor Score is computed from criterion ratings alone. It has no access to whether we are paid by a platform: the scoring formula takes ratings and nothing else, so a commercial relationship cannot reach it.

Frequently asked questions

What is the best prediction market?

On our scores at the update of 6 October 2026, Kalshi ranks first: a CFTC-designated exchange since 3 November 2020 with a published fee schedule. Polymarket has the widest range of markets, but its international site excludes US residents; Polymarket US is the separate, CFTC-designated exchange for them.

Which is best for you depends on where you live and what you want to trade, and every score here is preliminary and dated.

Which prediction markets can US residents use?

Exchanges the CFTC has designated as contract markets may list event contracts nationally. Among those we rank: Kalshi, Polymarket US, Interactive Brokers ForecastTrader (through ForecastEx), ProphetX and Novig. Several states dispute sports contracts in court, and offshore crypto venues such as polymarket.com exclude US residents. Our US list ranks only platforms open to US traders.

Are prediction markets legal where I live?

It depends entirely on your jurisdiction and on the platform. Each platform page shows the availability we have verified for your region, and our legality guides cover the major markets. This is not legal advice — check your local rules.

How is this ranking put together?

Every platform is scored 0–10 on nine weighted criteria: liquidity, fees, regulation, market variety, payments, UX, resolution, bonuses and support. The full weights are published on our methodology page. Commercial relationships are not an input to the score.

Why does every score say “preliminary”?

Because we refuse to guess at the part of the model we have not done the work for. Interface quality and support response time are unrated on every platform on this site: rating them means opening an account, placing trades and emailing a support desk, and nobody here has.

Liquidity is never measured by us — we hold no licence to redistribute the order-book and volume data that would do it, and a venue’s own marketing volume claim is not evidence; where a liquidity rating appears at all it is an inference from a book we opened and looked at, and its breakdown says so.

Resolution used to sit on that list of things we could not assess, and it did not belong there: how a venue determines an outcome, what recourse a trader has and whether disputes leave a public trace are set out in rulebooks, oracle documentation, terms of service and deployed contract code.

We have read them for the venues in this catalogue except Augur, which by its own FAQ has no prediction market you can currently trade on, and rating how well a venue resolves presumes a venue. A missing criterion is not scored zero — its weight is spread across the criteria we did rate — and below 80% coverage the score carries the preliminary badge you see.

Where does each rating come from?

Expand the score breakdown on any platform page. Every criterion we rated carries a comment naming the specific fact and the source it was read from — a regulator’s register entry with its date, a published fee schedule, a help-centre article on deposit minimums. Criteria we could not source are shown as unrated rather than filled in.

If a rating’s comment does not name evidence, it should not be there and we want to hear about it.

Do you earn money from these links?

From some of them. Where we do, the platform pays us a commission if you open an account, at no cost to you. Paid placements are labelled “Ad”. Compensation cannot affect an Editor Score — the function that computes it receives the nine criterion ratings and nothing else, so it has no way to know whether a platform pays us.
