How Kalshi Works: A Quick Guide for Traders
If you’re asking “how Kalshi works”, Kalshi is a regulated, exchange-style prediction market where users buy contracts that pay $1 if an event occurs. Prices reflect market-implied probabilities; you buy YES or NO contracts and cash out or hold to settlement. For arbitrage-focused traders, Kalshi is one venue among several — Polymarket is another, and PolyArb targets intra-Polymarket inefficiencies with a $7.62 minimum guaranteed edge per trade and low-latency execution.
What Kalshi does and how its contracts trade
Kalshi lists binary event contracts that resolve to $1 for a YES outcome and $0 otherwise. Contracts trade on an order book or via exchange mechanisms specific to Kalshi’s platform, and regulated status means KYC and clearing rules apply. Traders can take long or short stances by buying YES or NO, and price movement reflects changing probability and new information.
How this compares to Polymarket and where PolyArb fits
Polymarket is a decentralized CLOB on Polygon that uses pUSD and Gnosis’s CTF for outcome tokens; settlement is governed by UMA. Polymarket markets are gasless for end users via the Relayer. PolyArb is a third‑party arbitrage product built to operate on Polymarket: it locates intra-market discrepancies (e.g., complementary legs summing below $1.00), executes fast (40ms latency vs ~800ms for free bots), and notifies you via Telegram and Discord.
Why traders look for arbitrage between platforms
Arbitrage appears when similar event contracts are priced differently across venues or within a market’s outcomes. Kalshi’s regulated environment and Polymarket’s decentralized order book produce different liquidity profiles and latencies, so opportunities can exist. PolyArb focuses on intra-Polymarket arbitrage (buying complete sets when Σ best asks < $1.00) rather than cross-platform routing.
Practical limits and risks to consider
No trade is automatically without risk. Arbitrage faces resolution risk (UMA disputes on Polymarket), slippage and partial fills, fee changes, and settlement timing. Geographic and regulatory restrictions affect access to Kalshi and Polymarket; never bypass those restrictions. PolyArb is non-custodial and provides alerts, but understand operational and market risks before trading.

- No. Kalshi is a regulated exchange with its own contracts and KYC requirements. Polymarket is a decentralized CLOB on Polygon using pUSD and UMA for settlement.
- Can I arbitrage between Kalshi and Polymarket?
- Cross-platform arbitrage is possible in principle but involves extra friction: different settlement rails, KYC, and latency. PolyArb focuses on intra-Polymarket arbitrage and does not perform cross-platform routing.
- What does PolyArb provide compared with free bots?
- PolyArb offers 40ms latency execution versus roughly 800ms for many free bots, Telegram and Discord alerts, non‑custodial operation, and a stated $7.62 minimum guaranteed edge per trade. Review product terms and risks before using.
