Polymarket promo code ACTION gives new users a $50 bonus after a $20 deposit — trading credits you can put straight on Sunday's WNBA slate. Two games headline July 12: Sky vs. Wings at 7 p.m. ET on ESPN, then Fever vs. Aces at 9 p.m. ET on NBC. Sign up, enter the Polymarket referral code ACTION at registration, and deposit $20 to unlock the $50 bonus.
What the $50 Bonus Actually Is
It's a deposit match, not a free bet. Put in $20, enter Polymarket promo code ACTION, and Polymarket credits $50 in trading funds — leaving $70 to work with. The credits aren't withdrawable as cash, but the profit you make from trading them is yours after a one-time playthrough. Unused credits usually expire within 7–30 days, so put them toward this weekend's markets rather than letting them sit.

How the Bonus Works on WNBA Markets
Polymarket isn't a sportsbook. You buy contracts priced from $0.00 to $1.00, and each winning share settles at $1.00 — the price is the market's implied probability. Say you back the Over on the Fever–Aces total at an example price of $0.40: $50 buys 125 shares. A Yes settlement returns $0.60 per share, about $75 before fees; a No settlement loses the position. You can also sell before the final buzzer to lock in a gain or cut a loss, because prices move throughout the game. Contract price sets your share count — $50 buys 100 shares at $0.50, roughly 66 at $0.75.

Who's Eligible
Polymarket is a CFTC-regulated prediction market available in most states, but the bonus is excluded in AZ, IL, MA, MD, MI, MT, NV, and OH. You must be of legal age (18+ in most states) and have a U.S. address in a supported state. Rules in this space change fast, so confirm current availability at polymarket.us before you sign up.
Trade Responsibly
Size every position as entertainment, not money you need. Prices can drop before a market settles, so set a budget and don't chase a contract that turns against you. If gambling stops being fun or causes harm, call or text 1-800-GAMBLER for confidential support.
Must be 18 years or older and have a legal, U.S. residential address within the applicable state, D.C., or U.S. territories. Not available in AZ, IL, MA, MD, MI, MT, NV, and OH.
