Polymarket vs Kalshi
Polymarket leads on pure market depth and trading volume, offering a vast array of event contracts on politics, crypto, sports, and world affairs with a decentralized, crypto-native infrastructure that appeals to sophisticated traders who want tight spreads and genuine price discovery. Kalshi, by contrast, is the regulated US exchange operating under CFTC oversight, making it the clear choice for American residents who need legal certainty, USD deposits, and the peace of mind of dealing with a federally supervised entity. Polymarket's lack of formal US access (it geo-blocks American users following its 2022 CFTC settlement) is a decisive disadvantage for a large chunk of readers, while Kalshi's market selection and liquidity remain thinner than Polymarket's global book. Readers outside the US who prioritize liquidity and market variety should lean toward Polymarket; US-based traders who prioritize regulatory standing and fiat convenience belong on Kalshi.
