How the Polymarket Promo Code ACTION Offer Works
The Polymarket promo code ACTION is a flat bonus — deposit $20, get $50 in trading credits added to your account the moment your deposit clears. Unlike a traditional sportsbook's first-bet offer, there is no requirement to lose your opening trade to collect. Enter ACTION at signup, make your qualifying deposit, and your $50 bonus is ready to deploy on tonight's Dodgers vs. Phillies market or any other active contract on the platform.
Polymarket is the world's largest prediction market app. Unlike a sportsbook, where the house sets prices with a margin built in, every contract price on Polymarket is set by real traders reacting to real information. Each share is priced between $0 and $1, where the price represents the market's implied probability — a contract trading at $0.45 means the market gives that outcome a 45% chance of occurring. If it resolves in your favor, the share settles at $1.
Action Network's team tracks Polymarket contract prices alongside traditional market lines, and on nights with marquee MLB matchups like tonight's Dodgers-Phillies series, the platform consistently offers some of the most liquid and accurate baseball markets available to U.S. traders. That makes the Polymarket promo code ACTION $50 bonus one of the best starting points among prediction market promos.
Tonight's Game: Dodgers vs. Phillies at Citizens Bank Park — July 21
When: Tonight, July 21 | Where: Citizens Bank Park, Philadelphia | Starting Pitchers: Justin Wrobleski (LAD) vs. Zack Wheeler (PHI)
Here is where the Dodgers vs. Phillies match-winner market currently trades on Polymarket heading into tonight's first pitch:
| Outcome | Polymarket Implied Probability |
| Dodgers to win | 45% ($0.45) |
| Phillies to win | 55% ($0.55) |
The Phillies are favored tonight behind ace Zack Wheeler, who enters Game 2 with a 10-1 record and a 2.13 ERA — one of the most dominant pitching performances of the 2026 season and a legitimate Cy Young campaign. Wheeler gives Philadelphia a clear edge in this pitching matchup on paper.
The Dodgers counter with Justin Wrobleski, who has been one of the season's biggest surprises at 10-2 with a 2.69 ERA. The two-time defending World Series champions enter this series with the superior overall record at 63-37 against the Phillies' 55-45, and Los Angeles has had Philadelphia's number both earlier this season and in last year's NLDS. Shohei Ohtani leads off for the Dodgers while Kyle Schwarber anchors the Phillies lineup with an MLB-best 33 home runs — two of baseball's biggest individual storylines sharing the same field at Citizens Bank Park tonight.
Action Network's model gives the Dodgers a 56% win probability — a meaningful edge over their current 45% implied probability on Polymarket, making the Dodgers match-winner contract a potentially undervalued position heading into tonight's first pitch.
Action Network's Pick: Use Your Polymarket Promo Code ACTION Bonus on the Dodgers Tonight
