We're a couple of weeks away from the curtain being raised on the 2026-27 NFL season, so it's the perfect time to get signed up with the Polymarket promo code ACTION. The welcome offer requires a first-time $10 deposit, and that's all it takes to get a $20 bonus.
Polymarket is changing the game, defining itself as a regulated prediction market, not the same traditional sportsbook. Instead of betting on a sportsbook, users buy "Yes or No" contracts ranging from 1¢ to 99¢. A winning trade gets you the full $1 value of the contract, and there are no additional fees or penalties for a losing effort. When you place your trade, that doesn't have to be the end of the story; you can still add on, trim, or get out if things change during the game.
It's going to be a great day of preseason action on the NFL Network for Saturday, Aug. 22, with the Bills vs. Browns at 1 p.m. ET, followed by the Giants vs. Dolphins at 4 p.m. ET, Eagles vs. Patriots at 7 p.m. ET, and Cowboys vs. Cardinals at 10 p.m. ET. With this welcome offer, you can make your first deposit early in the day and then still have the rest of the night to unload your new reward.

Polymarket vs. Kalshi: NFL Preseason Odds, Picks for Bills vs. Browns
Market movements for the outright winner in the Bills vs. Browns game haven't moved much since the open, but they did swing quite dramatically at the beginning of the week. The Bills were initially getting a ton of backing (as high as 69%), and now we're seeing the Browns at 59%. I love a good swing, considering that is usually a good indicator of who gets the W.
| Prediction Market | Polymarket | Kalshi |
|---|---|---|
| Bills to Win | 42¢ | 42¢ |
| Texans to Win | 59¢ | 59¢ |
- Bills vs. Browns Pick: Browns to Win (59¢): If this were the regular season, I'd have a much different outlook on this game. However, the Browns are trying to establish themselves as a breakout team this season, and a strong performance could go a long way toward building confidence moving forward. On the other hand, the Bills are just trying to make it to the regular season healthy. I believe the massive shift in the market favors the Browns, and I'm taking them to win this one outright. Keep in mind, we just saw eerily similar positive market movements before Thursday's games, where the Raiders and 49ers both came out on top. I'm rolling with the trend and going with the Browns in this one!
