The Polymarket promo code ACTION lets new users collect $20 in bonuses. That $20 lands on the right night as The White Sox vs. Cubs comes from Wrigley Field this Tuesday 8:05 p.m. ET first pitch. TBS carries Game 2 of the Crosstown Classic nationally.
The $20 bonuses come from just a $10 deposit. This gives you $30 of total starting firepower in your balance, without having spent a cent. Comfortably the smallest buy-in among prediction market promos.
The Polymarket promo code ACTION offers more than the headline. Polymarket hands over the $20 the moment identity verification clears and the $10 deposit settles. No qualifying trade.
Sign up, verify, deposit $10, get $20, trade with $30.

Why use Polymarket for White Sox vs. Cubs?
Polymarket will have a ton of MLB markets available for fans this Tuesday, especially for the White Sox vs Cubs, being the nationally televised matchup.
Our experts have pulled out a few of their favorites for you to see where you might want to use your Polymarket welcome bonuses.
- Moneyline swings. Gausman's price moves fast once the Cubs bullpen warms up. With all eyes on this one, keep an eye on the market for opportunities.
- Total runs. A windy Wrigley Field is setting us up for a high total. Extra ball carry crucial tonight.
- Player markets. Pete Crow-Armstrong (28 HR, 30 SB) and Colson Montgomery (26 HR) draw heavy volume, especially at Wrigley.
How Do I Use the Polymarket Promo Code ACTION Bonus?
- Tap any Polymarket promo code link on this page
- Download the Polymarket US app.
- Enter promo code ACTION in the invite field during registration.
- Verify your identity. Name, address, phone, SSN. Most approvals clear in under six minutes.
- Deposit $10 by debit card, Apple Pay, bank transfer, or crypto.
- Get your bonuses. The $20 arrives automatically.
One Note for readers: The $20 arrives as trading credit rather than withdrawable cash, and it carries a 1x playthrough. Profits from those trades belong to you and withdraw normally, you cannot withdraw the $20 without having traded them.
How Does the Polymarket Promo Code ACTION Compare?
Every major prediction market app runs a welcome offer right now. Only the Polymarket promo code ACTION asks nothing beyond the deposit.
| Prediction Market | Welcome offer | Qualifying Trades | Bonuses |
|---|---|---|---|
| Polymarket | Deposit $10, get $20 | No trading required | $20 – Automatically |
| Kalshi | Trade $24, Get Up to $500 | $25 in cumulative trades first – | $15 – $500 – Random Amount (top 0.35% get $500) |
| ProphetX | Trade $10, get $20 | A $10 trade | $20 – After Trading Settles |
| Novig | Deposit $10, Get $25 in Trade Credits | No trading required | $25 – Automatically ( 5 Split wagers) |
The Polymarket referral code is separated from the rest of the field because:
- Kalshi's Promo Code is a lottery. Kalshi randomizes the payout between $15 and $500 after $25 of trades.
- Per Kalshi's random bonus tiers, roughly 70% of new users land on the $15 floor and about 0.35% hit $500. A massive $500 ceiling, but a $15 minimum, after risking $25 of your own money.
- ProphetX Promo Code needs trading. A $10 deposit alone earns nothing there. You must trade and risk your initial funds to earn the bonus.
- Novig Promo Code has troubles when spending. Novig splits the reward into five separate $5 trade credits, and each credit applies only to contracts priced between $0.01 and $0.60. That range excludes a lot of favorable trades, making it much harder to see any returns compared with Polymarket's no limit bonuses.
