SezgiX
Kalshi and Polymarket are the two best-known prediction markets, but they take very different approaches. This Kalshi vs Polymarket comparison covers regulation, onboarding, fees and market coverage in 2026, and shows where a global alternative like SezgiX fits.
Regulation and structure
Kalshi is a CFTC-regulated exchange in the United States. That regulation brings oversight, but also strict identity verification and a US-centric product. Polymarket is a decentralised, on-chain market settled in USDC on Polygon, which makes it crypto-native but subject to regional restrictions.
KYC and onboarding
Kalshi requires full KYC. Polymarket is largely KYC-free for trading but limits access in some regions. If frictionless, global onboarding matters to you, see our guide to prediction markets without KYC.
Fees
Kalshi charges exchange fees per contract. Polymarket has no platform commission but you pay network gas and effective spread. A 0%-commission venue removes most of that drag for active traders.
Markets and assets
Kalshi focuses on economics and event contracts; Polymarket is strong on politics and crypto. SezgiX spans crypto, sports, politics and finance in one place — browse the live markets.
