The Core Difference: Regulation vs Reach
Kalshi is a CFTC-regulated designated contract market — the fully legal, US-facing way to trade event contracts. You fund it with US dollars from a bank or debit card, complete KYC, and trade inside a regulated framework. The trade-off is a narrower, compliance-approved set of markets and US-only access.
Polymarket is crypto-native. You connect a wallet, trade in USDC on Polygon, and settle on-chain — no KYC, no bank. That opens up a much wider universe of markets (crypto, geopolitics, culture, sports) and global access, with the deepest liquidity on the biggest events. The trade-off: it operates offshore and has restricted US retail access since its 2022 CFTC settlement.
