Gemini, the Winklevoss crypto exchange, didn't partner with Kalshi; it got its own licence. The CFTC approved Gemini Titan as a Designated Contract Market on December 10, 2025 and Gemini Predictions went live on December 15 for customers in all 50 states, with yes/no contracts on sports, politics, crypto, economics and entertainment, traded from the same account and wallet as your crypto. It's a credible exchange with one gap: a fee schedule you can read before trading.
How it's built
Gemini Titan is Gemini's exchange entity, registered as a DCM in its own right. That puts Gemini in the group that controls its own order book, rules and settlement (Kalshi, Polymarket US, Novig, ProphetX, Crypto.com, Underdog) rather than the brokers (Robinhood, Coinbase, Plus500) that give you Kalshi's markets. Gemini also signed a letter of intent with Apex Fintech to distribute its contracts through other brokers, so its markets may appear inside apps you already use.
Markets
Sports (an NFL Trading Hub launched for the September 2026 season), politics, crypto prices, economics and entertainment. Contracts are priced 1¢ to 99¢ and pay $1. Prepackaged combos are offered on sports. Depth is behind Kalshi on most markets; Gemini's crypto-native user base shows in the crypto price contracts.
Fees
Gemini describes maker/taker pricing with maker rebates and ran a reduced-fee launch window. We could not find a complete, current public schedule, and the affiliate reviews that cover Gemini don't quote one either. Treat the order ticket as the source of truth and compare it on a 50¢ contract against Kalshi (1.75¢ taker) and Polymarket (1–1.75¢).
Money
You fund Predictions through your Gemini account: crypto, ACH, wire, debit or credit card, PayPal, Apple Pay, Google Pay. Withdrawals go out via crypto, ACH or wire with standard Gemini fees. If your money already lives on Gemini, this is the frictionless part.
Availability
Gemini says all 50 states and DC. Sports contracts are exposed to the same state actions as every other platform; don't expect them where Kalshi's are blocked. Non-sports markets should be broadly available.
Who it's for
Gemini customers, especially crypto-focused traders who want event contracts next to their holdings. Without a published fee schedule or Kalshi-level depth, it isn't yet a reason to move money there.
