Prediction market Kalshi: how it compares to Polymarket
If you searched for "prediction market Kalshi" you’re likely comparing platforms. Kalshi is a CFTC-regulated event market focused on binary event contracts; Polymarket is a decentralized CLOB on Polygon using UMA for resolution. For traders who want automated intra-Polymarket arbitrage, PolyArb offers a live, non-custodial bot ($99/mo) with 40ms latency, Telegram and Discord alerts, and a stated $7.62 minimum guaranteed edge per trade. Below I compare the user experience, resolution mechanics, and where PolyArb fits for latency-sensitive arbitrage.
What Kalshi is and how it differs
Kalshi runs CFTC-regulated event contracts with a centralized matching engine and fiat rails. It targets institutional and retail customers who need U.S. regulatory coverage. Settlement and product scope are constrained by CFTC rules, so some geopolitical or binary event types seen on decentralized platforms aren’t available. In contrast, Polymarket operates on Polygon with pUSD, uses the Gnosis CTF for outcome tokens, and resolves via UMA’s optimistic oracle.
Why traders care about latency and fees
Arbitrage depends on speed, execution quality, and fees. Latency affects how quickly you can capture brief mispricings; PolyArb advertises 40ms median latency versus ~800ms for free bots, which can mean the difference between a filled arb and a stale quote. Polymarket’s maker fees are zero and taker fees vary by category; builders can earn fees through the Builder Program while respecting relayer limits.
