The Offer
- Polymarket is offering a free $20 cash bonus to trade on anything when you sign up using the promo code POLYMADNESS
Our Verdict
As far as I know this is the only sign up bonus currently available for Polymarket. Polymarket is a prediction marketplace. This is basically just gambling with a different name so don’t sign up if you’re susceptible to that sort of thing. If you’re in two player mode you should be able to take two sides of a market and clear ~$40.
