Polymarket is a leading prediction market platform that recently returned to the US. You can trade on MLB games today and other real-world outcomes, all with transparent pricing in a user-friendly environment.
For example, the Braves are trading at 57% to take down the Padres, suggesting a 57% chance of that happening. If you purchase shares at that price and they come out on top, winning contracts settle at $1 each for a potential profit of $0.43 per contract.
Trading on MLB games at prediction markets is a different experience than wagering with fixed odds. The prices correlate to implied probabilities without the need for complex calculations, and liquid markets give you flexibility to enter and exit positions any time before a market resolves.
New users can claim the Polymarket invite code ALCOM for today’s MLB games and score a $50 trading bonus with an initial deposit of $20 or more. Check out complete Polymarket promo code details here.
Is Polymarket legit in Alabama?
Yes. Polymarket is legit in Alabama. The platform is regulated by the Commodity Futures Trading Commission and offers event contract trading on sporting events and a broad range of other topics. It operates under a designated contract market (DCM) framework and is subject to rules under the Commodity Exchange Act.
Polymarket is not a sportsbook that falls under the regulation of individual states. That opens up its availability across the majority of the US. For example, Dodgers fans out west could sign up with Polymarket promo code CA and trade on tonight’s game when they square off with the Phillies (6:40 p.m. ET on TBS).

This is the second of a four-game set for Padres vs. Braves. Atlanta took the opener 3-2 yesterday, a game that featured four solo homers, including what would prove to be the decisive blow from Ozzie Albies in the sixth inning. There was no scoring in the game until inning four, when Manny Machado went yard with a 402-yard shot. Since returning from the All-Star break, there has been a first-inning run scored in two of four games for Atlanta’s home stand. Tonight’s starters, Walker Buehler and Reynaldo Lopez, both allowed multiple runs in the opening inning of their last appearances, pointing to potential for some early fireworks.
The Nationals vs. Rockies is priced as a coin flip as they head to game two of a three-game set. Last night, Washington cruised to a 7-3 win, with Andres Chapparo getting the party started with a three-run homer in inning one. The over/under for tonight’s tilt is set at 12.5 runs, which makes perfect sense with a glance at this evening’s starters. Miles Mikolas brings a 5.53 ERA to the hill for the visitors, and squares off with Colorado’s Michael Lorenzen and his 6.22 ERA. Balls could be flying at Coors Field, with game time temps expected to be in the upper 80s.
