How the Polymarket Promo Code ACTION Works
The offer starts with a qualifying $10 deposit. Eligible new users who register through the promotion and fund their account receive a $50 trading bonus.
Unlike a traditional sportsbook, Polymarket uses event contracts whose prices move as traders buy and sell positions. A contract purchased at 67¢ costs $67 for 100 shares and settles at $100 if the selected outcome occurs.
The $10 entry requirement also makes this one of the lower cost offers among the best prediction market promos available this week.
Lions vs. Bills Polymarket Odds
Lions vs. Bills remains two days away, so Tuesday's prices should be treated as an early snapshot rather than the final Thursday Night Football market.
| Outcome | Polymarket Price |
|---|---|
| Bills to Win | About 67¢ |
| Lions to Win | About 34¢ |
| Bills -4.5 | About 51¢ |
| Lions +4.5 | About 50¢ |
| Over 53.5 | About 51¢ |
| Under 53.5 | About 50¢ |
Buffalo is the clear favorite in the outright market, while the spread and total contracts are much tighter. Paying around 67¢ on the Bills requires Buffalo only to win, whereas backing -4.5 adds the requirement that Josh Allen and the offense create more separation.
Prices can move significantly between Tuesday and Thursday, especially as final injury reports become clearer. Check Polymarket's live NFL odds before entering a position, since a lot can change between now and kickoff.
Lions vs. Bills Prediction
Buffalo gets the home field advantage for the first regular season game at the new Highmark Stadium, while Josh Allen enters Week 2 after another productive opener.
Detroit has enough offensive firepower to keep this competitive, but the Lions also enter the short week with offensive line injuries worth monitoring. That becomes particularly important against a Buffalo defense capable of putting pressure on Jared Goff.
The market reflects that gap. Buffalo is expensive enough outright that there is limited room for error, but the spread market is essentially split on whether the Bills can win by more than four points.

- Lions vs. Bills Prediction: Bills to win at 67¢ or lower
I prefer the outright winner contract rather than asking Buffalo to cover 4.5 points against another 1-0 team. Detroit can stay within one possession and the Bills contract still cash as long as Buffalo wins.
The total is also worth monitoring, but with two days of injury and market movement still ahead, the moneyline is the better Tuesday position.
