What Is the Polymarket Promo Code?

The Polymarket promo code is ACTION.It is a new-user welcome code entered once during registration on the Polymarket US app. Enter it before you finish creating your account, fund the account with at least $10, and Polymarket credits $20 in trading funds.

The code does two things: it flags your account as eligible for the current welcome offer, and it doubles your starting balance from $10 to $30 in usable funds. It does not need to be re-entered, and it cannot be applied retroactively to an account that already exists.

How to Claim the $20 Bonus With Promo Code ACTION

  1. Open the Polymarket US app on iOS or Android (or tap through from a verified promo link).
  2. Start registration with your email, then complete the identity details Polymarket requires — legal name, address, date of birth and SSN, standard for a CFTC-regulated exchange.
  3. Enter promo code ACTION in the promo, invite or referral code field before you finish signing up.
  4. Deposit $10 or more using your preferred method, including debit card and Apple Pay.
  5. Check your balance. The $20 trading bonus is applied automatically after the qualifying deposit settles.
  6. Find your market. Search "Dodgers vs. Cubs" for tonight's 8:05 p.m. ET first pitch and trade prediction markets.

The whole process typically takes under five minutes, with identity verification the only step that can add a delay.

How Polymarket Actually Works

Polymarket is a peer-to-peer prediction market app, not a sportsbook. Instead of taking a price set by a house, you buy and sell event contracts against other traders. Each contract is priced between $0.01 and $1.00, and that price reflects the market's implied probability of an outcome. If the outcome happens, the contract settles at $1.00. If it doesn't, it settles at $0.

Two consequences matter for a first-time trader:

  • You can exit early. As long as another trader will take the other side, you can sell out of a position before the event resolves, locking in a profit or cutting a loss.
  • Prices move on news. A pitching change, a rain delay, an early home run — the market reprices in real time, which creates entry points a fixed pregame line doesn't.

How to Use Your Trade Bonus on Dodgers vs. Cubs

The Cubs scored a massive 10-5 victory over the visiting Dodgers at Wrigley Field. Yet the Dodgers are back with their big guns, Skubal on the mound, Ohtani fresh off two hits and a run on Monday. 

Say you open a $20 position on the Dodgers vs. Cubs run line market (Dodgers -2.5) at $0.44 after you sign up and enter the Polymarket referral code ACTION. At $0.44 per contract, $20 buys 45 Yes contracts before fees.

If the Dodgers win by three or more runs, then Yes settles at $1.00; you profit $0.56 per contract. In this example, 45 contracts return $45 total, including $25 in profit. The opposite result risks the full position, so a losing $20 position drops to $0.

Your $20 trading bonus applies to a separate eligible market, not as profit from your first trade. Once credited under the promo rules, you can use the funds on another Dodgers vs. Cubs contract or hold them for future price shifts. Just keep in mind that contract prices can move against you before the market settles. 

Current Polymarket MLB market prices can change as trading activity increases.
