Hello
Almost everyone is looking for a sign-up bonus or incentive to join any prediction market. Here’s the scoop as of December 2025.
01
Kalshi
Kalshi offers a $10 sign-up bonus for new users who complete at least $100 in trades across any of its event contracts. This bonus is available to users in 45 states and does not require a deposit to qualify, though users must trade $100 in total.
02
Polymarket
Bummer. Polymarket does not currently offer a sign-up bonus or promo code for new users, especially in the United States, where the platform is not yet available.
03
PredictIt
Bummer. PredictIt does not offer any bonuses or other monetary incentives for signing up. Not for you and not for us. All we can do is get on there and spend our time seeking and speaking truth. We had worse…
04
Manifold
Oh yes, Mana for all of us. They’ll give you 1,000 Mana when you sign up. And when you invite new users to Manifold, and if they sign up and place a trade, you get 1,000 more in Mana! Mana, Mana, Mana…
