Is Kalshi real? What traders should know
Short answer: yes — Kalshi is a real, CFTC-regulated exchange that lists event contracts for U.S. retail and institutional traders. It differs from Polymarket in regulation, market access, and product rules. If you arrived here comparing platforms, this guide explains the practical differences and why traders building arbitrage strategies often look to Polymarket liquidity and tools like PolyArb.
What Kalshi actually is
Kalshi operates as a CFTC-regulated event exchange offering binary-style contracts on political, economic, and topical events for U.S. customers. Its regulatory status means specific legal and product constraints that differ from decentralised venues. Kalshi is focused on onshore compliance, KYC, and a traditional exchange model rather than blockchain-native settlement.
How Kalshi differs from Polymarket
Polymarket is a decentralised prediction-market exchange on Polygon using pUSD and CTF outcome tokens; it routes orders through a CLOB and settles via UMA. Key contrasts: Polymarket is crypto-native and accessible globally where not geo-blocked, while Kalshi is a regulated U.S. venue with KYC and different asset custody. These differences affect fees, access, and the speed at which markets appear or vanish.
Why traders choose Polymarket for fast arbitrage
Polymarket's CLOB structure and tokenised outcomes create rapid, high-frequency price dynamics that arbitrageurs exploit. Intra-market arbitrage — buying a full set when Σ bestAsk < $1.00 — can be fleeting. Tools built for that environment, like PolyArb, reduce latency and automate execution so traders can capture those short windows.
Where PolyArb fits in
PolyArb is a non-custodial arbitrage bot tailored to Polymarket markets. For $99/month it offers ~40ms latency versus ~800ms for many free bots, Telegram and Discord alerts, and a stated $7.62 minimum guaranteed edge per trade. It automates split/merge flows, monitors best asks across outcomes, and signals when an intra-market combinatorial or binary edge exists — while leaving custody and settlement to your wallet.
Risks and practical takeaways
No platform or bot removes all risk. Even when Σ bestAsk < $1.00, resolution disputes (UMA), partial fills, slippage, fee changes, and settlement timing can affect realized returns. If you evaluate Kalshi vs Polymarket for a strategy, match tooling and jurisdiction to your execution needs and risk tolerance.

FAQ
- Is Kalshi legally legitimate?
- Yes. Kalshi operates as a CFTC-regulated exchange in the United States, with KYC and onshore compliance obligations that differ from decentralised platforms.
- Can I arbitrage between Kalshi and Polymarket?
- Cross-platform arbitrage is possible in principle but complex in practice due to differing settlement rails, custody, geographic access, and timing. PolyArb focuses on intra-Polymarket arbitrage, not cross-platform trades.
- Does PolyArb work on Kalshi?
- No. PolyArb is built for Polymarket's CLOB and CTF mechanics on Polygon. Kalshi uses a different infrastructure and regulatory model, so PolyArb does not route orders there.
- What is the minimum edge PolyArb guarantees?
- PolyArb advertises a $7.62 minimum guaranteed edge per trade as part of its product positioning. Always weigh that figure against execution risk, fees, and resolution uncertainty.
