7 Polymarket alternatives worth considering in 2026
Polymarket is the highest-volume prediction market in the world, and after its 2025 return to the US through a regulated affiliate, it is squarely in the mainstream. Traders use it for sports, politics, crypto, macro, and cultural events, funded through USDC on Polygon or, more recently, a bank-backed on-ramp. The mobile app is newer than the web product, and a few pain points come up repeatedly in r/Polymarket and Discord threads: the USDC-first funding model still trips up first-timers who have never held stablecoins, state-level availability has gaps depending on the contract, resolution disputes on ambiguous markets can drag, and traders looking for pure sports depth sometimes want a dedicated exchange rather than a general market.
Here are seven Polymarket alternatives that cover prediction markets and event trading. Some are fully CFTC-regulated in the US, some sit inside a broker, and a couple are play-money platforms that let you sharpen forecasting skills before risking real capital.
| App | Best for | Free plan | Starting price/mo | Standout feature |
|---|---|---|---|---|
| Kalshi | CFTC-regulated US event trading | Yes | Free | Full 50-state availability |
| Robinhood | Event contracts inside a broker | Yes | Free | Sits next to your stocks and options |
| PredictIt | Politics-focused trading | Yes | Free | Academic-style position caps |
| Sporttrade | Sports event trading | Yes | Free | Live in-game contracts |
| Crypto.com | Wallet-integrated prediction markets | Yes | Free | Crypto-native deposit flow |
| Manifold | Play-money forecasting | Yes | Free | Risk-free skill building |
| IBKR ForecastEx | Event contracts for IBKR clients | Yes | Free | Inside Interactive Brokers |
Why people leave Polymarket
Crypto-first funding. Polymarket runs on Polygon with USDC as the base asset. Traders new to crypto need to buy USDC, understand gas, and manage a wallet. The 2025 US relaunch added simpler on-ramps, but the underlying model is still crypto-native.
State-level restrictions. Even after the regulated US return, availability of specific contracts (particularly election-related and single-state sports markets) varies by jurisdiction. Traders in some states find their favourite markets closed.
Resolution ambiguity. When a market's outcome hinges on subjective wording, resolution can be contested. Polymarket uses UMA's optimistic oracle, which is transparent but slow when a market is disputed.
App maturity. The mobile app is functional, but power users still prefer the web interface for order-book depth, chart granularity, and multi-market portfolio views.
Withdrawal friction for non-crypto users. Cashing out via USDC and then bridging back to a bank feels like extra steps compared with a broker-style deposit and withdrawal flow.
The 7 best Polymarket alternatives
Kalshi, best for CFTC-regulated US event trading
Kalshi is the largest CFTC-regulated Designated Contract Market in the US, live in all 50 states, with contracts covering sports, macro, weather, culture, and politics. The funding flow is bank-first: link a US checking account, deposit dollars, and trade. No stablecoin required. Kalshi's market list has grown quickly through 2025 and 2026, with football, basketball, and daily S&P 500 contracts pulling significant volume.
Where it falls short: Aggregate liquidity on niche markets still trails Polymarket in absolute dollars. Maker-taker fees apply on filled trades. Certain political contracts have been subject to ongoing CFTC and court review.
Pricing:
- Free: Account, trading
- Paid: Maker-taker fees per Kalshi's schedule
- vs Polymarket: Bank-first funding, full US coverage, narrower total volume
Migrating from Polymarket: Withdraw your Polymarket balance to USDC, off-ramp to a US bank, open a Kalshi account, and fund it directly by ACH.
Bottom line: Pick Kalshi if you want the cleanest US-regulated on-ramp and full 50-state access without touching crypto.
Robinhood, best for event contracts inside a brokerage
Robinhood rolled event contracts into its trading app through 2024 and 2025 and has kept expanding the market list. The main draw is unified accounting: event positions sit alongside stocks, options, ETFs, and crypto in a single balance, and funding runs through the bank link you already use for equities. Coverage now spans major US sports, Fed rate decisions, GDP prints, and macro milestones, with more markets added around big events.
Where it falls short: The contract list is narrower than Polymarket's global sweep. A handful of markets close before the underlying event resolves, which can trip up traders used to Polymarket's settlement rules.
Pricing:
- Free: Standard event contract trading
- Paid: Robinhood Gold ($5/month) for advanced features
- vs Polymarket: Built into a full brokerage, no crypto step, narrower market list
Migrating from Polymarket: Off-ramp USDC to a US bank, then transfer into an existing Robinhood account, or open one if you don't yet. Enable event contracts in your account settings.
Bottom line: Pick Robinhood if you already use it for stocks and want event contracts in the same login.
PredictIt, best for politics-focused trading
PredictIt has run political prediction markets in the US since 2014 under a CFTC no-action letter framework, in partnership with Victoria University of Wellington. The focus is elections, presidential approval, and policy events. Position caps keep the market small enough to look more like an academic experiment than an open trading venue, which is exactly what appeals to traders who want a slower, politics-only environment.
Where it falls short: Position caps (typically $850 per contract) and per-market trader caps limit real dollar exposure. PredictIt's regulatory relationship with the CFTC has been contested at various points, and the platform's long-term status has been an open question more than once.
Pricing:
- Free: Account creation
- Paid: 5% fee on profits, 5% fee on withdrawals
- vs Polymarket: Smaller stakes, narrower scope, no crypto step
Migrating from Polymarket: Off-ramp your Polymarket USDC to a US bank, open a PredictIt account, fund with a card or bank deposit, and focus on the political markets where PredictIt has its deepest history.
Download: PredictIt is primarily web-based. Use the mobile web interface at predictit.org on your phone's browser.
Bottom line: Pick PredictIt for politics-focused trading with academic-style limits and no crypto step.
Sporttrade, best for sports event trading
Sporttrade operates a CFTC-style exchange for sports outcomes, with live in-game contracts that let you buy and sell positions as a game plays out. Pricing is exchange-driven rather than book-driven, which means tighter spreads on liquid contracts and the option to cash out a winning position before the final whistle.
Where it falls short: Sporttrade is available in a limited set of US states. Outside major sports (NFL, NBA, MLB, NHL, soccer), depth thins quickly. Non-sports markets are not part of the product.
Pricing:
- Free: Account creation, trading
- Paid: Cost is built into the spread on contracts
- vs Polymarket: Stronger sports focus with live in-game depth, narrower state availability
Migrating from Polymarket: Confirm Sporttrade is available in your state, off-ramp USDC to a US bank, open a Sporttrade account, and shift sports trades there while keeping macro and culture markets on Polymarket.
Bottom line: Pick Sporttrade if sports event contracts are the main reason you traded on Polymarket and Sporttrade serves your state.
Crypto.com, best for wallet-integrated prediction markets
Crypto.com expanded into prediction markets through a dedicated section of its exchange app, with USDT and USDC-funded contracts on macro, crypto, and culture events. If you already hold funds on the platform, you can route them into prediction markets without a separate on-ramp, and the same wallet handles the payout afterward.
Where it falls short: Market depth varies. Sports and politics markets are thinner than Polymarket or Kalshi. Regulatory framework is exchange-based rather than CFTC-direct, and coverage depends on your state and country.
Pricing:
- Free: Account creation
- Paid: Trading and withdrawal fees per Crypto.com's schedule
- vs Polymarket: Same crypto rails, narrower contract list, everything inside one exchange
Migrating from Polymarket: If you already hold crypto on Crypto.com, fund prediction markets from the wallet directly. If not, the exchange onboarding adds a step.
Bottom line: Pick Crypto.com if you already use the exchange and want prediction markets in the same wallet.
Manifold, best for play-money forecasting
Manifold Markets is a play-money prediction market with millions of user-created contracts. Trading uses mana, a non-cashable internal currency, so there's no real capital at risk. For traders who want to sharpen forecasting calibration, test a strategy before deploying it on Polymarket, or model long-horizon questions without paying custody costs, Manifold is the easiest sandbox.
Where it falls short: No real-money payout. Because anyone can create a market, resolution standards on user-made markets are uneven. A few high-profile markets have been contested.
Pricing:
- Free: All trading
- Paid: Optional mana purchases for boosting positions (not cashable back to fiat)
- vs Polymarket: Skill development, no real stake, no real winnings
Migrating from Polymarket: Use Manifold as a paper-trading complement to a real-money platform. The two work well side by side: build calibration on Manifold, deploy capital on Polymarket.
Download: Manifold is primarily web-based at manifold.markets and works cleanly in mobile browsers.
Bottom line: Pick Manifold to build forecasting calibration without putting real money at risk.
IBKR ForecastEx, best for event contracts inside Interactive Brokers
ForecastEx is the CFTC-regulated event contract exchange operated by Interactive Brokers. It sits alongside IBKR's stock, options, futures, and FX offerings, available to any IBKR client who enables event contract trading. Markets cover macro, climate, and select event categories with IBKR's typical pricing transparency and no-frills execution.
Where it falls short: The market list is narrower than Polymarket's, and ForecastEx is gated to IBKR clients. The mobile app supports the product but with less charting depth than the desktop TWS platform.
Pricing:
- Free: ForecastEx access for IBKR clients
- Paid: Contract fees per IBKR's schedule
- vs Polymarket: Inside a full-featured broker, no crypto step, narrower list
Migrating from Polymarket: If you already trade at IBKR, enable ForecastEx in your account permissions. Otherwise the broker onboarding is heavier than Polymarket's crypto flow.
Bottom line: Pick ForecastEx if you already trade at Interactive Brokers and want event contracts in the same account.

FAQ
Is Kalshi better than Polymarket?
Kalshi has cleaner US regulatory standing as a CFTC Designated Contract Market and offers bank-first funding in all 50 states. Polymarket has higher aggregate global volume and a broader contract list. For US traders who want the simplest legal and funding experience, Kalshi wins. For pure liquidity and market breadth, Polymarket wins.
Are prediction markets legal in the US?
Kalshi and IBKR ForecastEx operate as CFTC-regulated Designated Contract Markets and are fully legal in all 50 states. Polymarket reopened US access through a regulated affiliate in 2025 and is available in most jurisdictions, with state-level variation on specific contracts. PredictIt operates under a CFTC no-action letter. Always check the platform's terms and any state advisories before trading.
What is the cheapest Polymarket alternative?
Manifold is free because it uses play money. Among real-money alternatives, Robinhood's standard tier and PredictIt have low or no upfront fees, though PredictIt charges 5% on profits and withdrawals. Sporttrade builds cost into the spread rather than charging a maker-taker fee.
Can I trade prediction markets without crypto?
Yes. Kalshi, Robinhood, PredictIt, Sporttrade, and IBKR ForecastEx all use standard fiat funding, typically through an ACH or debit card link. Only Polymarket and Crypto.com require or default to a stablecoin-based flow.
Is Polymarket available in every US state?
Availability varies by state after the 2025 regulated relaunch, particularly for election-related and single-state sports markets. Check Polymarket's terms for the current list before assuming a specific contract is open to you.
What do people use instead of Polymarket for sports event trading?
Sporttrade is the closest pure-play sports event exchange. Kalshi has grown quickly on football, basketball, and baseball contracts. Robinhood's event contracts cover major US sports inside the brokerage.
