What Kalshi is (quick primer)

Kalshi is a regulated event exchange operating under U.S. oversight where users can take positions on binary event outcomes. It targets a U.S. retail and professional audience and follows the compliance, reporting, and product rules required by its regulator. That regulatory model influences product availability, custody, and who can trade.

How Polymarket differs

Polymarket is a decentralised prediction-market exchange on Polygon using pUSD and the Gnosis CTF for outcome tokens. Trading executes on a Central Limit Order Book (CLOB) and settlements rely on the UMA optimistic oracle. Polymarket offers gasless trading via a Relayer and a different geographic access model compared with Kalshi.

Where PolyArb fits in

PolyArb is an execution tool for traders who want to capture intra-market arbitrage opportunities on Polymarket. It runs low-latency (40ms) monitoring and order routing, non-custodial wallets, Telegram and Discord alerts, and automated fills designed for binary and multi-outcome arbitrage. Pricing is $99/month and the product advertises a $7.62 minimum guaranteed edge per trade.

Choosing a platform based on goals

If you need a regulated, U.S.-facing contract venue and KYC, Kalshi may be appropriate. If you want decentralised markets, composable outcome tokens, and opportunities for intra-Polymarket arbitrage, Polymarket is the relevant venue. Use PolyArb when your objective is programmatic, latency-sensitive arb execution on Polymarket rather than a regulated betting app experience.
