How does Kalshi work: a concise trader's guide
If you’re asking “how does Kalshi work,” I’m not certain about Kalshi’s internal implementation details. Broadly, event exchanges let you buy and sell outcome contracts that pay $1 if the event occurs and $0 if it does not. Below is a practical comparison so you can see how Polymarket differs and where PolyArb (our arbitrage bot) fits.
A quick functional summary
At a high level, event exchanges list binary or multi-outcome contracts that trade like securities. Traders take positions by buying outcome shares; each share pays $1 on a YES resolution and $0 otherwise. Matching is done through an exchange engine that supports limit and market-style orders, order books, and real-time prices.
I’m not certain about Kalshi’s exact matching model or fee schedule. For Polymarket, trading runs on Polygon with pUSD settlement, a CLOB matching engine, and outcome tokens implemented via the Gnosis Conditional Token Framework.
Where Polymarket differs
Polymarket is a decentralized prediction-market exchange running on Polygon (chain ID 137). Settlement uses pUSD (wrapped USDC) and CTF outcome tokens. Polymarket sponsors gas through a Relayer so users trade gaslessly, and it uses UMA for resolution reporting.
Polymarket markets enforce that binary outcomes’ fair prices sum to $1, and multi-outcome markets’ prices sum to $1 across outcomes. Tick sizes, order types (including FAK market orders), and fee bands are part of its on-chain mechanics.
Why arbitrage matters and where PolyArb helps
Price inefficiencies—where summed best asks for all outcomes are below $1—create intra-market arbitrage opportunities. Exploiting them requires low latency, reliable fills, and quick CTF splits/merges.
PolyArb is a subscription arbitrage bot built for that workflow. For $99/month it provides ~40ms latency vs ~800ms for free bots, a $7.62 minimum guaranteed edge per trade, non-custodial execution, and Telegram + Discord alerts. It’s designed to find and act on intra-Polymarket spreads quickly; note trades still carry resolution, slippage, and settlement risk.
How to evaluate an event exchange
Compare matching model, settlement asset, fees, resolution process, and geographic access. Also weigh maker/taker fees, API quality, and whether gas is sponsored. Polymarket’s public APIs (Gamma, Data, CLOB) and WebSocket feed are explicit about endpoints and limits.
If your goal is systematic intra-market arbitrage on Polymarket, latency, order reliability, and builder/relayer access matter most—areas where PolyArb focuses its product.

FAQ
- Is Kalshi a prediction market like Polymarket?
- I’m not certain about Kalshi’s exact architecture. Generally, both platforms list event contracts that resolve to $1 or $0, but Polymarket is decentralized on Polygon and uses pUSD, CTF, and UMA for resolution.
- Can I arbitrage across Polymarket and Kalshi?
- Cross-platform arbitrage is possible in theory but involves extra latency, differing settlement assets, and regulatory or access constraints. PolyArb focuses on intra-Polymarket arbitrage rather than cross-platform strategies.
- What risks should I consider when arbitraging event markets?
- Key risks include resolution disputes (UMA), partial fills and slippage, fee changes, settlement timing, and smart-contract risk. No arbitrage is unconditional risk-free; the spread is mathematical but execution and settlement carry risk.
- How does PolyArb improve execution?
- PolyArb offers lower latency execution (~40ms), a $7.62 minimum guaranteed edge per trade, live Telegram and Discord alerts, and a non-custodial workflow for Polymarket intra-market arbitrage.
