With two marquee sporting events on the calendar Thursday night, here are my favorite picks for the Steelers vs. Packers and Phillies vs. Twins on Thursday, Aug. 13.
Steelers vs. Packers Prediction: Steelers ML (45%): Thursday’s Steelers-Packers preseason matchup should draw plenty of attention with Aaron Rodgers potentially facing his former team, and I’m still backing Pittsburgh despite uncertainty over his availability. I favor the Steelers at 45% on Polymarket, largely because of their stronger backup units and active offseason.
Phillies vs. Twins Prediction: Over 8,5 Runs (53%): Dyersville’s low fences, open cornfield sightlines, and humid August air historically create a hitter-friendly launching pad, as proven by the 17-run explosion in the inaugural Field of Dreams game. Combining these atmospheric advantages with power-hitting, high-fly-ball lineups in the Phillies and Twins, both pitching staffs face extreme friction that heavily favors backing the OVER.
The $20 promotional bonus can give new users additional funds to trade, but remember that trading on Polymarket carries risk. Once you've traded on Thursday's games, you can continue targeting markets such as MLB MVP, NFL Week 1 odds, or any other prediction market on Polymarket.

What is Polymarket?
Polymarket ranks among the best prediction markets in the US right now. Traders buy contracts tied to real-world outcomes — game results, elections, economic releases, and cultural events all sit on the board.
The structure separates it from a sportsbook. You trade against other participants rather than the house, and collective buying and selling sets every price. No bookmaker posts a number, and no built-in margin eats your return.
Polymarket promo code ACTION puts $30 in your account on day one: your $10 deposit plus $20 in site credit.
