Kalshi's API does not return CORS headers, so the browser can only confirm DNS, TCP and TLS reachability — not the JSON body. For the full exchange/trading flags, see Kalshi's official status page.

About Kalshi

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.

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.

Frequently asked

Is Kalshi down right now?
The dashboard above polls Kalshi's public exchange-status API directly from your browser. A green dot means the exchange and trading engine both report active.
Why can't I deposit on Kalshi?
ACH and debit deposits can be delayed during banking-partner outages, even when the exchange API reports healthy.
Is Kalshi legal in the US?
Yes — Kalshi is regulated by the CFTC and is legal in all 50 US states for the contracts it offers.

About this site

All data is provided on a best-effort basis with no guarantees about accuracy or availability. This is an unofficial status page and is not affiliated with, endorsed by, or sponsored by Kalshi.

Checks run client-side from your browser against Kalshi's public APIs. Latency therefore reflects your network path to the endpoint — not the server's health alone — and is subject to local clock skew, ISP routing, and browser scheduling.

If this page is showing "All Systems Operational" and you still believe Kalshi is degraded, the issue may be on an internal subsystem we cannot probe publicly (matching engine, custodial wallet, KYC, deposits). Cross-check the official Kalshi status page and their social channels before assuming a full outage.

Data sources: public Kalshi REST endpoints listed in the dashboard above. No private API keys are used. polymarket.health does not place trades, hold funds, or store user data.
