Best Polymarket Alternatives in 2025: Complete Platform Comparison
Whether you cannot access Polymarket from your location or want to diversify across platforms, here are the best prediction market alternatives in 2025.
Kalshi: The US-Regulated Alternative
Kalshi is the only CFTC-regulated prediction market platform available to US residents:
- Pros: Fully legal in US, real USD deposits, regulated
- Cons: Lower liquidity, fewer markets, US-only
- Best for: US traders wanting legal, regulated access
- Deposit methods: Bank transfer, debit card
- Fees: No trading fees, small withdrawal fees
Kalshi's regulatory status provides security that crypto platforms cannot match, but at the cost of market variety and liquidity.
PredictIt: Academic Research Platform
PredictIt operates under a CFTC no-action letter for research purposes:
- Pros: Legal in US, established reputation, politics focus
- Cons: $850 position limits, 10% profit fee, limited markets
- Best for: Political junkies wanting small legal positions
- Status: Currently winding down due to CFTC order
Note: PredictIt is no longer accepting new traders and is winding down operations following a 2022 CFTC order.
Metaculus: Forecasting Platform
Metaculus focuses on forecasting without real money:
- Pros: No financial risk, rigorous calibration, community
- Cons: No money at stake, less liquidity signal
- Best for: Improving forecasting skills, research
- Unique feature: Long-term questions and track records
Metaculus is excellent for honing probability estimation skills before risking real money on other platforms.
Manifold Markets: Play Money Platform
Manifold uses play money (Mana) for prediction markets:
- Pros: Anyone can create markets, no financial risk, active community
- Cons: Play money only (with limited redemption), some low-quality markets
- Best for: Market creation, practice, niche topics
- Unique feature: User-created markets on any topic
Great for testing strategies and tracking obscure topics, though the lack of real stakes affects market quality.
Augur: Decentralized Protocol
Augur is a fully decentralized prediction market protocol:
- Pros: Censorship-resistant, no KYC, truly decentralized
- Cons: Complex to use, low liquidity, gas fees
- Best for: Crypto natives wanting maximum decentralization
- Chain: Ethereum (with L2 integrations)
Augur sacrifices usability for decentralization. It is not recommended for beginners.
Betfair Exchange: Sports Focus
Betfair is the largest betting exchange, primarily for sports:
- Pros: Deep liquidity, established platform, sports expertise
- Cons: Not available in US, sports-focused, high commissions
- Best for: Sports bettors outside the US
- Unique feature: Election and novelty markets available
Betfair offers some political and novelty markets but is primarily a sports betting platform.
Smarkets: European Alternative
Smarkets is a UK-based betting exchange:
- Pros: Lower commissions than Betfair, clean interface
- Cons: Smaller than Betfair, not available in US
- Best for: UK and European traders
- Fees: 2% commission on net winnings
