What is Kalshi?
Kalshi is a federally-regulated dcm that lets users take positions on the outcomes of real-world events — sports, politics, economics, and culture. Founded in 2018, it operates under U.S. federal commodities law, which makes it available to traders in every US state.
What sets Kalshi apart is its positioning: the regulatory leader.. That's not marketing copy — it's reflected in the product, the markets offered, and the kind of trader who sticks around.
Is Kalshi legal in the US?
Yes. Kalshi operates as a federally-regulated venue, which means it falls under federal commodities law rather than state gambling law. Many US states' lack of legal online sportsbooks doesn't apply here — event contracts are a different financial instrument with different regulators.
That said, the legal picture is still being contested. Some state attorneys general have challenged certain platforms; the CFTC has consistently defended its jurisdiction. For the full backdrop, see our US legality guide.
What can you trade on Kalshi?
Kalshi covers World Cup, Sports, Politics, Economics, Culture. New markets are added weekly.
Practically, that means contracts on game outcomes, championship futures, player and team milestones, election results, Fed decisions, inflation prints, award shows, and cultural events.
How does Kalshi work?
Every contract on Kalshi resolves to either $1 (yes) or $0 (no). The price you pay reflects the market's implied probability — a contract at 62¢ means a 62% chance.
You don't have to hold to resolution. You can sell at any time — if the price moves to 78¢, you can lock in the gain. This is the single biggest mental shift from sportsbook betting: you're trading a price, not placing a wager. For the full mechanic, read how event contracts work.
How much does Kalshi charge?
Kalshi charges fees on a per-contract basis, typically a small fraction of a cent per contract or a low percentage of the trade. Compared to a sportsbook's 5-10% built-in vig, the fee structure is dramatically more transparent.
Liquidity varies by market — high-profile events like presidential elections or playoff series are deep, while niche markets can be thin. Always check the bid-ask spread before taking a position.
Is Kalshi safe?
Yes. Kalshi is regulated by the CFTC, segregates customer funds, and is required to meet federal compliance and reporting standards.
That regulatory backstop is the single biggest reason US traders choose federally-regulated venues over offshore sportsbooks, which operate outside U.S. consumer protection.
