Prediction markets have gone from a crypto-native curiosity to a $24 billion-per-month regulated financial category. In 2026, there are more platforms than ever — and the differences between them are meaningful. Wrong platform choice can mean paying 10x higher fees, missing markets you actually want to trade, or finding yourself blocked in your state.
This guide ranks and reviews every major prediction market app available in September 2026 — from the obvious choices to the newcomers worth watching.

Kalshi: CFTC-regulated (DCM); ~1.75% peak taker fee; best for general, political, and economic markets; available in most US states (8 blocked).

Novig: CFTC-regulated (DCM); 0% fees; best for zero-cost sports trading; available in all 50 US states.

Robinhood Predictions: CFTC-regulated; variable fees; best for existing Robinhood platform users; available in most US states.
#1 — Kalshi: Best Overall for US Traders
Best for: US-based traders who want the most regulated, most liquid political and economic markets
Kalshi is the gold standard of US prediction markets — a fully CFTC-regulated Designated Contract Market that operates more like a financial exchange than a betting platform. It's been the frontrunner for regulatory compliance since before prediction markets went mainstream, and that positioning paid off as the legal landscape clarified throughout 2025–2026.
What makes it stand out
In July 2026, Kalshi held 73% of combined Kalshi-Polymarket volume on overlapping markets — a significant lead driven largely by its strength in political and economic contracts. Its Federal Reserve decision markets generated over $26 million in single-event volume. If you want to trade macro events, Fed decisions, election outcomes, or legislative results, Kalshi has the deepest liquidity.
The mobile app is purpose-built and genuinely good — iOS and Android with a clean, intuitive interface that doesn't require you to understand crypto to use it. You deposit real USD via bank transfer, trade in dollars, and withdraw in dollars. No wallets, no stablecoins, no gas fees.
The fee structure
Kalshi uses a probability-weighted fee model: the peak taker fee of ~1.75¢ per contract applies when a market is priced near 50¢ (maximum uncertainty). As markets move toward certainty (90¢ or 10¢), fees drop significantly. For most trades, you're paying well under the stated maximum.
The catch
Kalshi is currently blocked in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, and Ohio following various state-level regulatory disputes. The Third Circuit sided with Kalshi in New Jersey in April 2026, but the Ninth Circuit ruled against it in Nevada in August 2026 — legal uncertainty at the state level continues. If you're in one of those states, Polymarket or Novig may be your best option.
Fee: ~1.75% peak taker (lower near certainty)
Minimum deposit: $10 USD (bank transfer)
Mobile: iOS + Android ✅
Markets: Politics, economics, sports, weather, elections
#2 — Polymarket: Best for Market Breadth and Lowest Fees
Best for: Traders who want the widest range of markets, the lowest fees, and don't mind crypto
Polymarket relaunched as a CFTC-regulated US platform on December 3, 2025, ending its period of US unavailability and fundamentally changing its competitive position. It's now available in all 50 states — and with fees of 0.30% taker (plus a 0.20% maker rebate), it's significantly cheaper than Kalshi for active traders.
What makes it stand out
Sheer volume and breadth. Polymarket hosts over 1,700 active political markets and 598 AI and technology markets — categories where Kalshi has limited coverage. Its September 2026 Federal Reserve decision markets generated $70 million+ in trading volume. The FIFA World Cup alone saw $3 billion in prediction market volume run through Polymarket.
If you want to trade an AI product launch, a specific congressional vote, a geopolitical outcome, or a crypto price milestone, Polymarket almost certainly has a market for it. Kalshi probably doesn't.
The iOS app launched publicly in May 2026 (removed the US waitlist) and Android is rolling out. Both feature biometric login and push notifications — a meaningful upgrade from the web-only experience of 2024–2025.
The catch
Polymarket runs on USDC (a USD-pegged stablecoin) on the Polygon blockchain. You need a crypto wallet (Metamask or similar), you fund it with USDC, and withdrawals are in USDC that you convert back to dollars. For traders comfortable with crypto, this is a non-issue — the costs are minimal and the conversion is straightforward. For traders who've never touched crypto, there's a real learning curve.
Fee: 0.30% taker / 0.20% maker rebate
Minimum deposit: $10 USDC (Polygon)
Mobile: iOS ✅ / Android (rolling out)
Markets: Politics, AI/tech, sports, crypto, economics, culture — broadest selection
#3 — Novig: Best for Sports Trading (Zero Fees)
Best for: Sports-focused traders who want to eliminate fees entirely
Novig became a CFTC-designated market in June 2026 and launched nationwide on August 4, 2026 — one of the newest entrants in the regulated space, and arguably the most interesting fee structure in the market: 0% on both makers and takers.
That's not a promotional rate — it's their model. Novig generates revenue through other means, which lets them offer genuinely zero-commission sports prediction markets. For high-frequency sports traders, the cost savings compound significantly over time. Running 100 trades per month that would cost 1% each on a competitor? Novig saves you a meaningful amount.
The platform is sports-exclusive — no politics, no economics, no AI markets. If that's your primary domain, Novig deserves serious consideration. The minimum age is 21+.
Fee: 0%
Minimum deposit: Varies
Mobile: Available
Markets: Sports only
US availability: All 50 states

#4 — ProphetX: Best Peer-to-Peer Sports Exchange
Best for: Sports traders who want transparent peer-to-peer exchange without house margin
ProphetX transitioned from a sweepstakes model to a fully CFTC-regulated exchange in June 2026, registering as both a Designated Contract Market (DCM) and a Derivatives Clearing Organization (DCO) — one of only a handful of platforms to hold both designations.
What makes ProphetX different: it's a true peer-to-peer exchange for sports markets. You're never trading against a house line — you're matched directly with other traders, with transparent commission-based pricing and no hidden margin baked into the odds. This is structurally fairer than most sports betting, and more similar to how financial exchanges work.
Best for experienced sports traders who understand order books and want maximum price transparency. The minimum age is 19+.
Fee: Commission-based (no house margin)
Mobile: Available
Markets: Sports only
US availability: Most states
#5 — DraftKings Predictions: Best for Sports Bettors Making the Transition
Best for: Sports bettors already in the DraftKings ecosystem who want to try prediction markets
DraftKings launched its predictions product in December 2025 across 38 states (with sports markets available in 17). If you already have a DraftKings account and are comfortable with their interface, the predictions product is the lowest-friction way to start trading event contracts.
The current market selection is narrower than dedicated prediction market platforms — skewing toward crypto price targets (Bitcoin, Ethereum) and sports outcomes. It's a solid on-ramp, not a destination for serious prediction market traders. Fees are higher than Polymarket and Novig.
Fee: Varies by market
Mobile: Full DraftKings app integration
Markets: Sports, crypto
US availability: 38 states
#6 — Robinhood Predictions: Best for Existing Robinhood Users
Best for: Investors already using Robinhood who want prediction markets without a new account
Robinhood's Predictions feature has been growing fast — it traded 2.5 billion contracts in October 2025 alone and was tracking toward $100 million in annualized revenue as of late 2025. For existing Robinhood users, the integration is seamless: same app, same account, same funding.
The trade-off is selection depth. Robinhood Predictions covers major markets (election outcomes, Fed decisions, major sporting events) but doesn't have the breadth of Kalshi or Polymarket. It's a convenient add-on for people already in the Robinhood ecosystem, not a standalone recommendation for serious prediction market traders.
Fee: Varies
Mobile: Full Robinhood app ✅
Markets: Politics, sports, economics (curated selection)
US availability: Most states
#7 — PredictIt: Best for Political Market Specialists
Best for: Traders who want deep coverage of niche political races and down-ballot events
PredictIt has been around longer than any other major prediction market platform in the US, and its niche remains intact in 2026: unmatched depth in down-ballot and niche political contracts. You'll find markets on state legislature races, judicial appointments, and obscure regulatory decisions that don't exist on Kalshi or Polymarket.
The catch is the fee structure — it's brutal for active traders. A 10% commission on profits plus a 5% withdrawal fee can eat more than 14% of your gross winnings on a successful trade. That's not competitive with modern prediction markets. PredictIt makes sense if you're trading specific niche markets that don't exist elsewhere; it doesn't make sense as your primary platform.
Fee: 10% on profits + 5% withdrawal
Minimum deposit: Varies
Mobile: Web-based
Markets: Political focus, exceptional niche depth
US availability: Most states (restrictions apply)
#8 — Manifold Markets: Best for Beginners and Practice
Best for: Anyone new to prediction markets who wants to learn before risking real money
Manifold uses entirely play money (virtual "mana") — no real funds, no regulatory hurdles, no financial risk. It's the best way to understand how prediction markets actually work: how order books function, how to read contract prices as probabilities, how markets reprice when news breaks.
The community is active and markets cover a wide range — politics, tech, AI, sports, meta-forecasting questions. Once you've developed a sense for calibration on Manifold, you can move to Kalshi or Polymarket with real money and a much clearer understanding of what you're doing.
It also functions as a serious forecasting community. Many of Manifold's most active users are forecasters and superforecasters who use it as a calibration tool rather than a money-making vehicle.
Fee: Free
Mobile: iOS + Android
Markets: Everything (community-created)
US availability: All states (no real money)

What to Watch: Emerging Platforms in 2026
OG.com — Sports-focused with a flat $0.02 per contract fee structure (predictable costs). Growing but smaller than the leaders.
FanDuel Predicts — Fantasy sports audience crossover, $10 minimum, 2% fee on potential payout. Good for existing FanDuel users.
Omen — Decentralized prediction market for Web3 and DAO governance use cases. Not a mainstream recommendation, but relevant for crypto-native users.
The market is consolidating around a handful of CFTC-regulated leaders. Expect more M&A activity — IG Group's acquisition of Underdog in July 2026 for up to $1.3 billion signals how much institutional appetite exists for this space.
What Changed in 2026: Key Developments
December 2025: Polymarket relaunches in the US as a CFTC-regulated platform — the biggest single development of the year.
May 2026: Polymarket iOS app removes US waitlist; available on the App Store for all US users.
June 2026: CFTC issues comprehensive proposed rule framework for evaluating event contracts — regulatory clarity increases. Novig and ProphetX both receive DCM designations.
July 2026: IG Group acquires Underdog for up to $1.3 billion — signals mainstream financial industry legitimacy.
August 2026: Novig launches nationwide with 0% fees — immediately pressures sports market pricing across competitors.
August 2026: Ninth Circuit rules against Kalshi in Nevada (state gaming license requirement) — a reminder that state-level legal battles aren't fully resolved.
Fees: The Full Breakdown
Fees have an outsized impact on returns in prediction markets — especially because most contracts resolve in days or weeks rather than years. A 2% fee on a contract you hold for 30 days is a 24% annualized drag. Here's the honest fee picture:
Novig: Completely fee-free (0% taker and maker fees, no extra charges).
Polymarket: 0.30% taker fee, 0.20% maker rebate, plus minimal crypto gas fees on withdrawals.
Kalshi: Up to ~1.75% taker fee (lower for makers), with rates dropping as outcomes reach near certainty.
DraftKings: Fees vary and are built directly into the spread.
FanDuel Predicts: 2% fee on payouts, with total costs increasing on higher volume.
PredictIt: 10% fee on profits plus a 5% fee on all withdrawals.
For active traders, the fee differential between Polymarket (0.30%) and PredictIt (10% + 5%) is massive. Over 100 trades, Polymarket's cost advantage compounds into a significant P&L difference.
Frequently Asked Questions
Which prediction market app is best for beginners?
Start with Manifold Markets — it uses play money so there's zero financial risk while you learn the mechanics. When you're ready for real money, Kalshi has the cleanest onboarding for US users: USD deposits, no crypto required.
Is Polymarket available in the US in 2026?
Yes — Polymarket launched a CFTC-regulated US version in December 2025 and removed its US waitlist from the iOS App Store in May 2026. It's available in all 50 states.
What's the difference between prediction markets and sports betting?
The structural difference is who you're trading against. In sports betting, you trade against the sportsbook's house line — the house has a built-in edge. In prediction markets, you trade against other users on an order book. The platform takes a small fee, but there's no house margin built into every trade.
Do prediction market apps have mobile versions?
Kalshi has full-featured iOS and Android apps. Polymarket has an iOS app (Android rolling out). Most other platforms have either mobile apps or mobile-optimized web interfaces.
Which app has the most markets?
Polymarket — over 1,700 active political markets and 598 AI/tech markets as of September 2026. It has the widest coverage of any platform in almost every category except niche US political races, where PredictIt goes deeper.
Are all prediction market platforms legal in the US?
The major platforms listed here are all CFTC-regulated. However, state-level availability varies — Kalshi is currently unavailable in 8 states due to ongoing regulatory disputes. Polymarket and Novig are available in all 50 states. Always verify your state's current status before depositing.
Our Verdict
There's no single "best" prediction market app — the right choice depends on what you want to trade and how you want to fund it:
- You're a US trader who wants simplicity: Kalshi
- You want the lowest fees and widest markets: Polymarket
- You only trade sports: Novig (zero fees) or ProphetX (peer-to-peer)
- You're already in the DraftKings or Robinhood ecosystem: Use their native prediction features
- You're brand new to prediction markets: Manifold first, then Kalshi
The prediction market space has matured dramatically in 2026. Every major platform on this list is now CFTC-regulated — the cowboy era of unregulated crypto betting on Polymarket is over. What's replaced it is a genuinely competitive market of regulated exchanges competing on fees, markets, and user experience.
The winner right now on value-for-money is Polymarket. The winner on regulatory clarity and US-friendliness is Kalshi. Most serious traders will end up with accounts on both.
