Why people look for Kalshi alternatives

Three reasons drive almost every search:

  1. You’re not in the US. Kalshi is a CFTC-regulated US-domestic exchange. International users cannot register, full stop.
  2. You don’t want US-bank-grade KYC. SSN, Plaid, ID verification, bank linking. For users used to crypto sportsbooks or DeFi, this feels like overkill.
  3. You want crypto funding. Kalshi accepts ACH and debit only — no crypto, no instant settlement to a self-custodied wallet.

Each alternative below addresses at least one of these directly.

#1. Roobet — Best Kalshi alternative for international users

Roobet’s prediction markets product launched in 2026 and is the strongest option for non-US users who want a Kalshi-style experience without the bank-grade onboarding. The platform is crypto-native end to end: you fund in BTC, ETH, USDT, SOL, LTC, DOGE or XRP directly to a custodial wallet, deposits land in minutes, and crypto withdrawals settle in minutes too. KYC is light and country-dependent — no SSN, no Plaid, no bank linking.

Where Kalshi specialises in US political and macro depth, Roobet is currently strongest on sports, crypto, esports and entertainment markets, with politics and macro depth growing. The genuine differentiator vs Kalshi is that you also get a full sportsbook (16+ sports, moneylines, spreads, totals, live betting) and a 6,300-game casino in the same wallet — neither of which Kalshi offers.

The structural trade-off: Kalshi has CFTC oversight and issues 1099-MISC forms for US tax filing. Roobet operates under a Curaçao gaming licence. If you’re a US resident, Kalshi is the right answer regardless. If you’re outside the US, Roobet is the practical answer.

Best for: International users (Canada, LatAm, Nordics, EU ex-restricted, parts of Asia and Africa) who want crypto-native event trading with light KYC.

Where it falls short: Restricted in the US, UK, France, Germany, Netherlands and several other countries. No US-domestic regulator equivalent.

#2. Polymarket — Best for political market depth

Polymarket is the deepest crypto-native prediction market in the world, with billions in volume across the 2024 US election cycle and unmatched depth on US politics, regulatory milestones, and long-tail macro futures. For users specifically looking for the depth that draws professional traders to Kalshi-style markets, Polymarket is the alternative.

Trade-offs vs Kalshi: Polymarket is officially geo-restricted from the US (and so is Kalshi if you’re outside it — they’re mutually exclusive in practice). Funding requires USDC on Polygon, which means a bridge step that Kalshi’s Plaid-and-ACH approach avoids. Resolution is on-chain via UMA’s optimistic oracle.

Best for: Non-US users comfortable with self-custody and USDC bridging who want maximum political and macro market depth.

Where it falls short: USDC + Polygon bridge friction. Officially geo-restricted from the US.

#3. Smarkets — Best for UK and EU regulated trading

Smarkets is a UK Gambling Commission-licensed exchange that operates much like a prediction market — peer-to-peer matching on event outcomes — denominated in GBP and EUR. For UK and EU users who want a regulated equivalent to Kalshi without the US-only restriction, this is the closest match.

The platform charges 2% on net winnings per market, withdrawals to UK banks usually settle same-day, and the market range covers politics, sports, entertainment and current affairs. It’s not crypto-native, but it’s the most regulated option for non-US/non-crypto users.

Best for: UK and EU users who want regulated event trading in fiat with same-day withdrawals.

Where it falls short: No crypto funding. Lower volume than Polymarket on US-centric markets.


#4. Limitless — Best on-chain alternative

Limitless is an on-chain prediction market on Base (Coinbase’s L2). It uses an orderbook model with USDC funding on Base, and gas costs are typically lower than Polygon’s. For users who specifically want the self-custody, on-chain trading model — but find Polymarket’s depth overkill or prefer the Base ecosystem — Limitless is a clean alternative.

Best for: On-chain-first users who want a Polymarket-style experience on Base.

Where it falls short: Significantly thinner liquidity than Polymarket. Still requires bridging to Base and using a self-custodied wallet.


#5. Manifold — Best for learning without risk

Manifold uses play-money instead of real cash, with anyone able to create a market on any topic. The market range is massive — politics, science, entertainment, niche internet drama — and prices on liquid markets track reality reasonably well. It’s the best place to learn the mechanics of prediction markets without putting real money at risk.

Best for: Anyone learning prediction markets, or users who want to trade niche markets that wouldn’t make a real-money venue.

Where it falls short: Not real money. Price quality is lower on illiquid markets.
