Kalshi stocks: how they compare to Polymarket and PolyArb

If you searched “kalshi stocks” you’re likely comparing event-based contracts across platforms. Kalshi is a regulated event-exchange offering user-facing event contracts; Polymarket is a decentralised prediction market on Polygon. For traders focused on intra-platform arbitrage, PolyArb is a specialised bot that runs on Polymarket: non-custodial, live today, $99/month, 40ms latency, Telegram and Discord alerts, and a $7.62 minimum guaranteed edge per trade.

What Kalshi offers

Kalshi is a centralized, CFTC-regulated exchange that lists event contracts spanning macro, politics, and sometimes market-related questions. Its product is built for retail and professional users who want regulated event betting with fiat rails and KYC. I’m not certain about the exact catalogue of “Kalshi stocks” as a named product; if you mean stock-linked event contracts, availability and settlement rules depend on Kalshi’s listings and CFTC permissions.

How Polymarket differs

Polymarket is a decentralised prediction-market exchange running on Polygon, using pUSD as the settlement asset and the Gnosis Conditional Token Framework for outcome tokens. Trading on Polymarket happens through a CLOB with gas sponsored by the Relayer and resolution via the UMA optimistic oracle. That infrastructure makes Polymarket more permissionless and crypto-native compared with a regulated venue like Kalshi.

Why traders choose PolyArb for arbitrage

PolyArb is built specifically for intra-Polymarket arbitrage: the bot detects combinatorial and binary spreads, places FAK orders, and alerts you via Telegram and Discord. The product is non-custodial and runs at 40ms latency (versus ~800ms for many free tools). Subscriptions are $99/month and include a $7.62 minimum guaranteed edge per trade, which is presented alongside the usual arbitrage caveats.

Risks and practical differences

No trade is unconditional risk-free. On Polymarket you face resolution risk (UMA disputes), settlement timing, slippage, partial fills, fee changes, and smart-contract risk. Kalshi’s regulated model brings KYC, fiat rails, and a different dispute/settlement framework, which may suit traders who prioritise regulation over decentralisation.

Which to use depending on your goals

If you want regulated fiat rails and CFTC-backed contracts, Kalshi may meet that need. If you want intra-platform arbitrage on a decentralised CLOB and low-latency automated execution, PolyArb on Polymarket is purpose-built for that workflow. PolyArb is non-custodial, live today, and provides alerts and a guaranteed minimum edge to subscribers.
