The first and only fully CFTC-regulated prediction exchange in the US, funded in plain US dollars. It's the volume leader — a record $31B in June 2026 — and our top pick for most American traders.
Kalshi is our top pick for most US readers, for one decisive reason: it is the only major prediction market that is federally regulated by the CFTC as a Designated Contract Market. You fund it with dollars, your money sits in segregated accounts, and for non-sports markets it’s broadly available nationwide. In June 2026 it cleared a record ~$31 billion in volume, so liquidity is rarely a problem.
If you’re coming from a sportsbook, or you simply want the most legitimate, lowest-friction way to trade events in the US without touching crypto, start here.
Kalshi charges a variable trading fee that scales with price — it’s largest around 50¢ and falls to zero at the extremes. Bank and wire deposits are free; debit-card withdrawals carry a small fee. Read the current fee schedule before trading larger size.
Kalshi’s sports contracts are the flashpoint in a fast-moving state-by-state legal fight — available and federally defended in some states (a federal appeals court blocked New Jersey’s enforcement in April 2026), restricted or contested in others (Nevada, Michigan, New York and more). Always check our legality tracker for your state first.
