About Kalshi
Kalshi is the first CFTC-regulated event-contract exchange in the United States, offering legal binary prediction markets on economics, weather, climate, and politics. We hit the public Get Exchange Status endpoint and the Markets API on every poll to confirm the exchange and trading engine are healthy.
Kalshi at a glance
How Kalshi works (under the hood)
Kalshi was founded by Tarek Mansour and Luana Lopes Lara in 2018 and became the first CFTC-regulated event-contract exchange in May 2021. After a multi-year legal battle, an October 2024 federal court ruling affirmed Kalshi's right to list election contracts; the platform now operates legally in all 50 US states.
Unlike crypto-native markets, Kalshi is a fully regulated derivatives exchange: customer funds sit in segregated US bank accounts, every contract is certified or approved by the CFTC, and trades clear and settle through traditional financial infrastructure — no wallets, no oracles, no chains.

Fees
Kalshi's fee schedule varies by contract and is taken on profitable closes — typically 1% to 7% of profit. Losing positions are not fee-charged. There are no deposit fees on ACH; debit card deposits incur a small processor fee. Withdrawals are free and settle in 1–3 business days.
Liquidity & activity
Liquidity is concentrated on flagship contracts (Fed rate decisions, monthly CPI, presidential elections, weekly sports). Top contracts routinely show $100K+ book depth at each price level; long-tail contracts are thinner and benefit from designated market makers.
Notable incidents
- Nov 2024 — Brief login slowness during election night peak; trading remained available.
- Sep 2024 — Court ruling triggered sudden volume surge; brief deposit-processing queue.
How it differs from other platforms
Kalshi is the only major platform where US users can legally trade with regulated funds custody. The tradeoff: a narrower, regulator-approved catalog. Polymarket lists thousands of markets Kalshi cannot. PredictIt is academic with strict limits. Manifold isn't real money.
What to watch during a live event
Kalshi's biggest load spikes are Fed decision days, CPI releases at 8:30am ET on the second Tuesday of the month, and election nights. Trading engine slowness usually shows up here as elevated latency on the exchange-status probe before the front-end degrades visibly.
During legal or regulatory news (a new CFTC action, an appellate ruling), watch the deposit-processing queue: sudden signup surges can slow ACH funding to 24–48 hours even when trading itself is fine. This page cannot probe the KYC or deposit pipeline directly.
If you rely on the API for programmatic trading, subscribe to the Kalshi status page directly for scheduled maintenance windows; those are usually announced 24–72 hours in advance and are not reflected here in real time.

Data & methodology
Checks run from your browser every ~45 seconds. Latency reflects your network path to the endpoint, not the server alone. Historical uptime is logged hourly via an independent worker (rolling 30-day window). Kalshi's API does not return CORS headers, so the browser confirms DNS / TCP / TLS only.
- Get Exchange Status— Official endpoint for exchange + trading-engine flags.
- Markets API— Active markets feed.
- Events API— Event groupings.
- Developer docs— Full Kalshi trade API reference.

About this Kalshi status mirror
Our Kalshi mirror hits the official Get Exchange Status endpoint plus the Markets and Events feeds on api.elections.kalshi.com. Because Kalshi's API does not return permissive CORS headers to browsers, this page confirms DNS, TCP and TLS reachability from your network, then relies on the exchange-status endpoint (which does return an opaque response we can time) for engine health.
Kalshi is a CFTC-regulated Designated Contract Market — even a full API outage does not put your funds at risk, because custody sits in segregated US bank accounts and clearing runs through a separate DCO. This page tracks trading availability, not solvency.
This is an unofficial status page and is not affiliated with, endorsed by, or sponsored by Kalshi.
