Sign-up offers and referral codes, dated

Prediction market promo code is one search with four different answers, because the venues do four different things, and two do not run what people are looking for at all. Each card says what the offer pays and the condition that decides whether it pays you.

Novig

FRESH · 4 DAYS

The one venue that publishes its terms in numbers. Give $25, get $25: your friend gets $25 in Trade Credits after a $10 deposit, you get $25, capped at five referrals or $125 for life. You must already have five trades and $50 at risk before you can refer anyone.

Kalshi

NO AMOUNT PUBLISHED

Kalshi uses real codes, but states the reward, the trading requirement and the lifetime cap only inside your own account. Any dollar figure quoted elsewhere is a number Kalshi does not publish, so we do not print one.

Betfair · Sporttrade

We find no Betfair Exchange referral code, only promo codes on its other products. Sporttrade stopped taking wagers on 25 May 2026 and now shows only a waitlist, so no Sporttrade code is real right now.

A stale promo page is worse than no page: it burns the one thing this site sells, which is being right on the date shown.
