What Kalshi is and how it lists government shutdown markets

Kalshi is a regulated exchange that offers binary event contracts for US-focused political and economic events, including government shutdowns. Its product suite is designed for US customers under a CFTC-compliant model and uses KYC for trading access. Liquidity and fees behave like an exchange; market structure and settlement differ from Polymarket’s CTF and UMA-based resolution.

How Polymarket pricing differs for a government shutdown

Polymarket lists similar binary markets but runs on Polygon using pUSD and the Gnosis Conditional Token Framework. Outcome prices on Polymarket are ERC-1155 tokens that sum to $1.00 at fair value. That means intra-market spreads sometimes create clear mathematical edges: when best-ask(YES) + best-ask(NO) < $1.00 you can buy both legs and lock the difference, subject to resolution and execution risks.

Why traders choose PolyArb for event arbitrage

PolyArb is a paid bot built for intra-Polymarket arbitrage: $99/month, 40ms latency versus ~800ms for many free bots, Telegram and Discord alerts, and a stated $7.62 minimum guaranteed edge per trade. It’s non-custodial and focuses on fast detection and execution of intra-market binary and multi-outcome opportunities. Remember the spread is mathematical but not without risk: UMA disputes, partial fills, slippage, and settlement timing can erode returns.

Practical steps when you see a Kalshi vs Polymarket divergence

Don’t assume identical liquidity or fees across platforms; check order books, tick sizes, and whether you can legally trade the platform from your jurisdiction. If you trade Polymarket arbitrage, confirm taker fees for the market category, expected slippage, and that you can split/merge/redeem outcome tokens. Use tooling that watches for rapid tick_size_change and last_trade_price updates.

FAQ

Is a Kalshi government shutdown contract the same as Polymarket’s?
No. Kalshi is a U.S. regulated exchange with its own settlement and KYC requirements. Polymarket runs on Polygon with pUSD, CTF outcome tokens, and UMA for resolution. Prices may align but mechanics and access differ.
Can PolyArb trade across Kalshi and Polymarket?
PolyArb focuses on intra-Polymarket arbitrage. Cross-platform arbitrage involving Kalshi is out of scope for PolyArb’s bot.
What risks exist when arbitraging event markets like a government shutdown?
Key risks are resolution disputes via UMA, smart-contract and settlement timing risk, slippage and partial fills, fee changes, and geographic access restrictions. These can reduce or eliminate the apparent mathematical edge.
How quickly does PolyArb alert me to opportunities?
PolyArb advertises 40ms latency for detection versus ~800ms for many free bots, and provides Telegram and Discord alerts for live arbitrage opportunities.
