Best prediction market apps in 2026

The best prediction market apps let you trade event contracts — on sports, elections, the economy, the weather — from your phone. Every platform below ships its own iOS or Android app, and they are ranked by Editor Score.

An app is only as useful as the account behind it, so every entry shows whether it is open where you are. In the US that means CFTC-regulated apps such as Kalshi and Polymarket US; polymarket.com itself is for users outside the US.

Ranked platforms

  1. Kalshi

    7.7/10preliminary

    Widest range of regulated US markets

    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.

  7. Polymarket US

    7.3/10preliminary

    Polymarket’s markets, for US residents

    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.

  8. Polymarket

    6.9/10preliminary

    Deepest order books, outside the US

    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.

  9. ProphetX

    5.9/10preliminary

    Sports, with fees on net gains only

    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.

4. DraftKings Predictions

Standalone DraftKings prediction markets app trading on CFTC-regulated exchanges

6.3Prelim

Strengths

  • The most thorough per-contract contingency drafting of the US brokers — a named source agency, a 48-hour clock and an explicit revision rule
  • Broker and exchange both verifiable on the regulators’ own records
  • Specifications are fixed as of the first day of trading, so terms cannot move under an open position
  • A flat $0.01 per-contract fee rather than a formula that peaks at the midpoint
  • Certifications are openly fetchable with no login

Watch out

  • Its own Rule 9.5(b) promises published disciplinary notices and no such page exists
  • Certifications defer the decisive parameters to “the Market Specifications”, a term the rulebook never defines
  • Markets trade with no matching certification — hundreds of soccer contracts settled on a day when no soccer certification exists
  • Older generic certifications reserve an override “for any reason or no reason”
  • The rulebook names no regulator as a customer remedy for a disputed outcome
  • Every DraftKings web address blocks our fetcher, so we have never read a live contract page

5. 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

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

What is a prediction market app?

A prediction market app is the phone version of an exchange where you buy and sell event contracts — yes-or-no contracts that pay $1 if something happens and nothing if it does not. A contract at 62¢ is the market saying roughly 62%. You trade with other users, not against the app, and you can sell before the event is decided. What event contracts are and how to read contract prices cover the mechanics.

Are prediction market apps real? The regulated ones are run by exchanges on the CFTC’s register: Kalshi (designated 3 November 2020), Polymarket US (QCX LLC, 9 July 2025), Novig (Ludlow Exchange, 16 June 2026) and ProphetX (11 June 2026). FanDuel Predicts sells contracts listed by CME Group, and Crypto.com’s are listed by Crypto.com Derivatives North America. Ratio is different again: a social app that copies other traders’ orders onto Polymarket rather than an exchange of its own.

What you can trade in a prediction market app

  • Kalshi: the widest verified range — 14 categories in its own API, from climate and weather, economics and elections to sports, entertainment, science and technology, and transportation.
  • Polymarket US: sports, politics, crypto, economics, weather, tech and culture, plus multi-leg combos.
  • Novig and ProphetX: sports — winners, spreads, totals, props, futures and parlays across the major US leagues.
  • FanDuel Predicts: index, commodity, crypto and economic-data contracts plus sports, by FanDuel’s own release; no politics book is named.
  • Crypto.com: politics, financials, culture, economics and sports, by its own product page.

Apps where you can bet on anything

People looking for an “app where you can bet on anything” usually mean a prediction market app: they list contracts on almost any question with a verifiable answer — a Fed decision, an inflation print, an award, an election, tomorrow’s high temperature — not just sports. On a regulated app it is a trade, not a bet: you buy a contract from another user, and the app earns a fee.

“Anything” has limits. US law lets the CFTC bar event contracts involving terrorism, assassination, war, gaming or unlawful activity as contrary to the public interest, and every contract has written rules that decide how it settles. Read them before you trade: how a prediction market resolves explains what to look for. How this differs from a sportsbook is set out in prediction markets vs sports betting.

Are prediction market apps legal in the US?

Under federal law, yes, when the app is run by or lists contracts on a CFTC-designated exchange. Several states dispute that for sports contracts, and some have won orders — against Kalshi in Nevada, Washington and Michigan, for example. Eligibility follows where you are when you trade, so an app can work in one state and geofence you in the next. Our US availability page and the 17 state pages linked from it list every app with the rule that applies.

Age is set by each app: Novig requires 21; Polymarket US and ProphetX require at least 18 and the age of majority where you are. polymarket.com does not accept US residents and directs them to Polymarket US. The full legal picture is in are prediction markets legal in the US?.

How to sign up and fund a prediction market app

  • Download it from the official App Store or Google Play listing, and check that the developer name matches the operator in our review.
  • Verify your identity. Regulated apps require it: Kalshi before you can trade, Polymarket US before any deposit, ProphetX at account opening.
  • Allow the location check. Apps confirm which state you are in when you trade, not only where you live.
  • Deposit. Kalshi’s minimum is $10 ($1,000 by wire) by debit card, Apple Pay, Google Pay, bank transfer, PayPal, Venmo, Cash App, crypto or wire. ProphetX’s is $10. Novig charges 3% on card and Apple Pay deposits; bank and stablecoin deposits are free.
  • Check the welcome offer’s terms before you use it — most are trading credits you cannot withdraw. Each operator’s own terms are on our bonuses page.

What a trade costs in each app

Fee schedules differ more than the headline numbers suggest, so compare them on the size you trade:

  • Kalshi: taker fee 0.07 × price × (1 − price) per contract — 1.75¢ at 50¢, rounded up.
  • Polymarket US: taker fee up to $1.74 per 100 contracts at 50¢; makers receive a rebate.
  • Novig: no fee on pre-game straight trades; takers pay a price-based fee on live trades, futures and parlays.
  • ProphetX: 2% of net gains per market on straight trades, so a losing position pays nothing.
  • Crypto.com: $0.01–$0.0175 per contract for takers, nothing for makers.

Fees and the true cost of a trade shows how to compare them, and the expected value calculator tells you whether an edge survives the fee.

How to check an app is safe

  • Look up the operator’s legal entity on the CFTC’s register of trading organisations and, for brokers, on the National Futures Association’s BASIC search. A brand name alone proves nothing.
  • Be wary of any app or ad that promises returns. Every contract can lose its full price.
  • Turn on two-factor authentication, and never share the code with anyone who contacts you claiming to be support.
  • Know where your money sits: on a designated exchange customer funds are segregated — what CFTC designation means explains what that does and does not protect.

Prediction market apps for sports

Most app downloads are for sports.

How to choose

We rank the platform, not the app store rating. Interface quality is one of the criteria we have not yet rated on any platform, because rating it means opening funded accounts; when we do, it will change these scores and the page will say so.

Browser-only platforms are not on this list, but several of them work well on a phone. The full ranking includes them.

Frequently asked questions

What is the best prediction market app?

On our scores as of 1 October 2026, Kalshi ranks first among apps, for the widest range of regulated US markets. The best one for you depends on what you trade: Novig for low-fee pre-game sports, Polymarket US for Polymarket’s markets in the US, and polymarket.com for depth if you are outside the US.

What is a prediction market app?

A phone app for trading event contracts: yes-or-no contracts that pay $1 if an event happens. Prices from 1¢ to 99¢ read as probabilities, you trade with other users rather than against the app, and you can sell before the event is decided.

Are prediction market apps legal?

In the US, apps run by or listing on CFTC-designated exchanges — Kalshi, Polymarket US, Novig, ProphetX and others — are legal under federal law. Some states dispute sports contracts in court, so availability can depend on the state you are in when you trade.

Are prediction market apps legit?

Check the operator, not the app: a legitimate US app names a legal entity you can find on the CFTC’s register. Kalshi, Polymarket US, Novig and ProphetX are designated exchanges. Treat any app that promises returns or has no named regulator with suspicion.

Which prediction market app is best for sports?

For sports specifically, Novig charges no fee on pre-game straight trades and ProphetX charges 2% of net gains only; Kalshi and Polymarket US list sports alongside everything else. Our sports ranking compares them all.

Do prediction market apps require ID verification?

The regulated ones do. Kalshi requires identity verification before you can trade, Polymarket US before any deposit, and ProphetX at account opening.

What is the minimum deposit on a prediction market app?

Kalshi’s is $10 ($1,000 by wire) and ProphetX’s is $10. Others do not all publish one; each review states what the operator documents.

Can I use prediction market apps outside the US?

Some. polymarket.com serves users outside the US, and Kalshi accepts some international users with restrictions by country and fewer deposit methods. US-only apps such as Polymarket US and Novig do not.
