What Kalshi is and how it differs

Kalshi is a US-regulated exchange offering event contracts where contracts settle based on the occurrence of real-world outcomes. It operates under a regulatory framework different from prediction markets built on Polygon. Kalshi’s product and settlement model are distinct from Polymarket’s CTF outcome tokens and pUSD settlement. For a trader, the practical differences are market access, KYC requirements, and product design. Kalshi may suit institutional participants needing regulated contracts; Polymarket is designed for rapid, on-chain order-book trading where intra-market arbitrage opportunities can appear and vanish within seconds.

How Polymarket intra-market arbitrage works

On Polymarket you buy outcome shares (ERC-1155 CTF tokens) priced in pUSD. In a binary market, fair prices sum to $1.00; when the sum of best asks falls below $1.00, buying the complete set locks in the edge equal to $1.00 minus that sum. PolyArb automates detecting those opportunities, placing orders, and executing split/merge operations through Polymarket’s relayer.

Why PolyArb for traders comparing platforms

If your workflow is search-driven (e.g. "nyc mayor kalshi") and you want live arbitrage on Polymarket, PolyArb offers 40ms latency versus ~800ms for free bots, Telegram and Discord alerts, and non-custodial execution for $99/month. The bot surfaces intra-market binary and multi-outcome edges and claims a $7.62 minimum guaranteed edge per trade as part of its product terms.

Risks and practical limits to expect

Do not treat every spread as risk-free. Polymarket-specific risks include UMA dispute or resolution delays, partial fills and slippage on the CLOB, fee changes, and smart-contract risk. Geo-restrictions also matter: some countries cannot open new orders on Polymarket. PolyArb reduces execution latency but cannot eliminate oracle, regulatory, or protocol risk.
