Trade qualifying pro football contracts and Gemini matches 50% of your volume, up to $100 in Predict Cash.
Gemini Predictions gives new users a 50% trade match, paid as up to $100 in Predict Cash, on qualifying pro football trades. No promo code is required, since the offer applies automatically when you sign up through our link. The match is calculated on your qualifying trading volume, so you earn it by placing trades you were already planning to make.
Gemini is the crypto exchange founded by Cameron and Tyler Winklevoss, and its prediction market runs inside that same account. Read our full Gemini Predictions review for a closer look at how the platform works.
The bonus is paid as Predict Cash, which is promotional credit that cannot be withdrawn and can only be used on eligible Predictions contracts. Predict Cash expires 30 days after it is credited. Only the first qualifying purchase in each distinct market counts toward the match, and trades outside the 20 to 80 cent window do not qualify. Some promotional pages describe the top tier as a single $500 trade, but Gemini’s own structure points to roughly $200 in qualifying volume, so check the offer screen for the exact threshold before you trade.
Takers, who match an existing order, pay 0.07 times the number of contracts times the price times one minus the price. That peaks at about $1.75 per 100 contracts at a 50-cent price and shrinks toward the edges. Makers who post resting orders pay a lower rate that is waived on qualifying trades through December 31, 2026. ACH and wire deposits are free, PayPal deposits carry a 2.5% fee, and ACH withdrawals are free.
Gemini’s rewards for existing users are built around trading volume rather than a rotating promo calendar. The Taker Rewards Program pays daily USD rewards that scale with trailing taker volume, plus a monthly bonus, and it was extended through December 31, 2026. Higher reward rates require significant volume, so it mainly benefits frequent traders. Maker fee waivers through the end of 2026 add another layer of savings for anyone who posts resting orders.
Gemini’s offer is a match on your trading volume, so the more you trade on qualifying football contracts, the more you earn, up to $100. The catch is that the bonus is non-withdrawable Predict Cash with a 30-day clock and a narrow 20 to 80 cent price window. Kalshi’s welcome offer works as a straight trade-and-get bonus, which is simpler to hit but varies by promotion. For football fans who are comfortable with mid-priced contracts, Gemini’s match can be the larger payout. See our Kalshi promo code page for the full breakdown of that offer.
