Kalshi alternatives: every real option in 2026
Published 2026-05-22 · Last reviewed 2026-05-22
TL;DR
- Polymarket is the closest alternative if you're outside the US.
- PredictIt is the only other US-legal real-money venue, capped at $850/market.
- Manifold is the best free play-money alternative.
Kalshi is the default, not the only option. Here's everywhere else US traders actually go — and where each one wins.
Why look beyond Kalshi?
Kalshi is the best overall US venue, but it has real gaps: a smaller catalog than Polymarket, 1–7% trading fees, and limited coverage of long-tail topics. Depending on what you want to trade and where you live, an alternative may suit you better.
1. Polymarket — biggest catalog, non-US users
Polymarket has more markets than every other venue combined, charges 0% trading fees, and settles on-chain in minutes. The hard limit: US users are geo-blocked.
US residents: Polymarket geo-blocks US IPs and its terms of service prohibit US users. See Is Polymarket legal? before signing up.2. PredictIt — US-legal, capped at $850
PredictIt runs under a CFTC no-action letter, accepts US users, and excels at political markets. The $850-per-market cap means it can't be your primary venue but it can supplement Kalshi when a specific political contract is only listed on PredictIt.
3. Manifold Markets — free play-money
Manifold uses in-app 'mana' rather than real money. Best for calibration practice before you trade real money anywhere else, and for trading exotic markets nobody else lists.
4. On-chain newcomers — Limitless, Drift BET, Augur V2
A wave of new on-chain prediction markets launched through 2025–2026 on Base, Solana, and Ethereum L2s. Liquidity is thin and the US-legality picture is unclear. Watch but don't deposit serious money without checking volume and resolution-backlog first.
Which alternative fits you?
- Non-US, want more markets and cheaper fees → Polymarket.
- US, specific political market only on PredictIt → PredictIt.
- Just learning, want to test calibration → Manifold.
- Want to experiment with on-chain markets → start with Polymarket, then sample Base/Solana venues with small size.
