Prediction market apps you can use in Missouri 10
KalshiEX is a CFTC-designated contract market and its Member Agreement names no US state as restricted. State court orders block some contract categories in Nevada, Washington and Michigan; elsewhere its contracts are available. Kalshi is in litigation with about 20 states, so this can change quickly.
Help centre: “currently available in all U.S. states”, though some event contracts may be unavailable in some states (not named). App Store: “Available in all 50 US states”. New York has separate funding and portfolio articles.
“Novig is available nationwide, except in Arizona, Nevada, and Michigan.” Eligibility is based on physical location at the time of trading, and users must be 21 or older.
FanDuel Predicts is available in all 50 states and DC. Users must be 18+ and verify their identity. It is not available on or near tribal land.
Prediction Trading (and Sports Event Trading) is a CFTC-regulated feature of the Crypto.com App, offered through Crypto.com | Derivatives North America. The help centre says it is available in the US only.
DraftKings' own availability page (updated 2026-07-22) lists 48 states for Predictions, plus DC and US territories. Access depends on physical location and excludes tribal land. Sports markets vary by state; the breakdown is shown only as an image that could not be read. The official availability page and Predictions Terms returned 403.
QCX LLC publishes no list of eligible or excluded states. A Nevada court granted a preliminary injunction against QCX LLC d/b/a Polymarket US on 29 May 2026 (Nevada Gaming Control Board). Missouri's Attorney General has sent a cease-and-desist over sports contracts, and New York has announced a lawsuit; neither state is marked closed because the operator has not said it geoblocks them.
The international polymarket.com site is closed to US residents: no deposits and no trades. The help centre lists the US as blocked and the API docs list it as close-only. US residents are sent to the separate Polymarket US app, run by QCX LLC (a CFTC DCM). Polymarket US state-level eligibility was not verified because its ToS page loads its text client-side.
ProphetX says it is “available nationwide” but publishes no excluded-state list; its help centre says access “is restricted from certain locations and IP addresses”. Connecticut reportedly ordered it to stop offering sports contracts to residents (September 2026); the order could not be read on the regulator’s site.
Only in states where Underdog Predict operates: "Must be 18+ and present in a state where Underdog Predict operates". The operator's state list (help centre) could not be read, so other states are unconfirmed.
