Best prediction markets for sports

Every scored platform that lists sports markets, in one list. They are not the same product: some are CFTC-regulated exchanges and brokers selling event contracts to US customers, others are offshore on-chain order books, and the difference decides who can use them and how a dispute is settled.

Ranked by Editor Score, with availability for your region on every entry. Sports contracts are where the legal picture moves fastest — several US states have challenged them — so check the review before you fund an account.

2. 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

3. 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

  • Fastest listing of new events
  • No maker trading fees under the published schedule
  • Public API with full order book access

5. Hedgehog Markets

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

6. Opinion

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

5.7Prelim

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
  • No stated jurisdiction of incorporation, licence or regulator

7. Predict.fun

Non-custodial event contracts on BNB Chain, with yield on USDT collateral

5.4Prelim

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

8. Space

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
  • No volume or depth data is published

9. Probable

BNB Chain prediction market with a published Predict.fun acquisition notice

1.8Prelim

Strengths

  • A public acquisition notice identifies Predict.fun as the acquiring platform

Watch out

  • Independent trading availability after the acquisition has not been verified
  • The refund and migration process has not been tested
  • Current operator, fees, eligibility and custody terms remain incomplete

How to choose

A sports contract is priced like a probability, not like a bookmaker’s odds: a 60¢ YES pays $1 if the team wins, and the platform’s cut is a fee on the trade rather than a margin built into the price. Compare the fee on the contract size you actually trade, and how much you can buy at the quoted price — thin books move against a large order.

If you already bet with a sportsbook, our guide to how prediction markets differ from sportsbooks explains what changes: you trade against other users, you can sell before the game ends, and the settlement rules are written into each contract.
