How the Polymarket Sign Up Bonus ACTION Works
The Polymarket sign up bonus ACTION is a deposit-based welcome offer rather than a first wager safety net. Eligible new users create an account, complete the required verification and make a qualifying $10 deposit to receive $50 in bonuses from one of the best prediction market promo codes.
Polymarket operates differently from a traditional sportsbook. Users trade event contracts whose prices generally range from 1¢ to 99¢ based on what participants are willing to pay. A winning contract settles at $1, while an incorrect position settles at $0.
Those prices can move throughout the day as traders enter and exit positions. That means the Lions or Bills contract available Thursday morning may not carry the same price shortly before kickoff.
Users new to the format can review Action Network's how to bet on Polymarket guide, while the broader prediction markets hub explains how event trading differs from conventional sports betting.
Lions vs. Bills Polymarket Odds
Buffalo enters Thursday Night Football as the favorite on Polymarket NFL odds, with the outright market giving the Bills roughly a two-thirds chance of winning their home opener.

|---|---|
| Bills to Win | About 67¢ |
| Lions to Win | About 34¢ |
| Bills -4.5 | About 51¢ |
| Lions +4.5 | About 50¢ |

Lions vs. Bills Thursday Night Football Preview
Thursday's game marks Buffalo's first regular season matchup at the new Highmark Stadium in Orchard Park.
The Bills enter after a 36-31 Week 1 win over Houston in which Josh Allen threw two touchdowns and added two more on the ground. Detroit also needed all four quarters and overtime to move to 1-0, beating New Orleans 31-30.
Detroit's offensive line remains one of the biggest variables entering Thursday. Christian Mahogany has dealt with hip and knee issues, while Blake Miller and Juice Scruggs have also appeared on the injury report during the short week. Cade Mays remains unavailable.
The Lions also continue to manage injuries in the secondary, creating another matchup to watch against Allen and Buffalo's passing game.
Buffalo has its own injury situations, but the Bills enter Thursday with fewer major questions surrounding the starting lineup. Final availability should still be checked before trading because late injury news can move prediction market prices quickly.
Lions vs. Bills Prediction
Buffalo is the preferred side, but the outright contract is more appealing than Bills -4.5 spread.
- Lions vs. Bills prediction: Bills to win at 67¢ or lower
Detroit is capable of keeping this within one possession. Jared Goff has enough skill talent around him to generate points, and Buffalo allowed Houston to score 31 in Week 1.
The difference is that the Bills do not need to create separation for the 67¢ winner contract to settle. Buffalo gets Allen at home for the first regular season game in its new stadium, while Detroit enters with uncertainty along the offensive line and secondary.
At 67¢ or lower, I would rather back Buffalo to win than pay roughly 51¢ and require the Bills to cover 4.5 points.

How Polymarket Compares With Other Prediction Market Apps
Polymarket is one of several platforms offering NFL event contracts, and prices do not have to match from one exchange to another.
Action Network's best prediction market apps rankings compare the major platforms by factors such as sports coverage, market selection and availability.
The full Polymarket review goes deeper on the platform itself, while the Kalshi vs. Polymarket comparison breaks down two of the most prominent options for NFL traders.
That makes it worth comparing prices before taking a Lions Bills position rather than assuming every prediction market will offer the same contract at the same price.
Conclusion
The Polymarket sign up bonus ACTION gives eligible new users $50 in trading credit after a qualifying $10 deposit ahead of Lions vs. Bills on Thursday Night Football.
After the initial welcome bonus, Polymarket's referral program creates another path to promotional credit. Users can earn $25 for each qualifying referral, up to 14 friends and another $350.
That brings the combined promotional potential to up to $400 for users who satisfy all applicable welcome and referral requirements.
