How the Polymarket Promo Code LABS Offer Works
The Polymarket promo code LABS is a flat bonus — deposit $20, get $50 in trading credits added to your account with no strings attached. Unlike a sportsbook’s first-bet offer, there’s no requirement to lose your opening trade to collect. Enter the Polymarket referral code LABS at signup, make your qualifying deposit, and your bonus is ready to use on any active market with one of the best prediction market apps.
Unlike traditional sports betting, Polymarket contracts reflect pure crowd intelligence — the price on a Yankees win contract tonight moves in real time as lineups are posted, weather conditions update, and sharp money flows in ahead of first pitch. That makes the platform particularly well-suited to MLB, where late-breaking information like a scratched ace or a lineup stack against a lefty can shift market prices meaningfully before the game begins.
Tonight’s Featured Trade: Yankees @ Rays, 6:40 p.m. ET on TBS
The headliner on tonight’s national slate is the New York Yankees visiting Tropicana Field to take on the Tampa Bay Rays at 6:40 p.m. ET on TBS. The Yankees and Rays are two of the most heavily traded MLB franchises on Polymarket, and a nationally televised matchup between them draws some of the highest contract volumes of any regular-season game. Use your Polymarket promo code LABS bonus to take a position on the game’s match-winner market before first pitch tonight — then check Action Network’s MLB picks and projections page for the latest model-driven analysis before committing your bonus credits to a specific contract.
The Dodgers hosting the Rockies at 10:10 p.m. ET is also worth watching for late-night traders — Los Angeles is one of the most consistently traded franchises on the platform, and late-game Pacific time kickoffs typically see significant price movement in the final hour before first pitch as any lineup news drops.
