California and New York are both on the eligible-state list, so both Rams and Bills fans can claim the Kalshi promo code ACTION55 before kickoff if they meet the offer requirements. This Kalshi sign up bonus is one of several NFL prediction market promos available this week, but its $55 reward comes after just $25 in qualifying trades, making it one of the best options available.
How the Kalshi Offer Works for Bills vs. Rams
Complete $25 in qualifying trades with Kalshi promo code ACTION55 attached to your account and Kalshi adds $55 after the offer requirements are satisfied. The reward is tied to qualifying trade volume on NFL odds and other markets rather than whether your first position wins or loses.
Kalshi operates as a CFTC-regulated exchange where users trade event contracts. Contracts are generally priced between 1¢ and 99¢, settle at $1.00 if the outcome occurs and $0 if it does not, and can be sold before settlement if there is liquidity.
The contract price also gives you a quick read on market expectations. A Rams winner contract trading at 62¢ on prediction market apps, for example, reflects a market-implied probability around 62%.
Unlike a traditional sportsbook wager, you can also sell an open position before settlement if there is enough liquidity. That ability to enter and exit positions is one of the core differences covered in our guide on how to bet on Kalshi.

Bills vs. Rams Prediction
Buffalo's defense creates the biggest concern entering Monday night. The Bills rank 30th in opponent EPA per play and 28th in success rate, and New England just beat them 29-26 in Orchard Park. Now Buffalo heads across the country for a matchup with Matthew Stafford and a Rams passing attack capable of stressing that defense again.
Puka Nacua makes the matchup even tougher. He returned from his hip injury against Philadelphia with nine catches for 125 yards, and he posted 12 catches for 162 yards the last time Buffalo visited SoFi Stadium. Kyren Williams also gives Stafford a reliable short-area option after catching 10 passes against the Eagles.
Buffalo still has Josh Allen, which keeps this from looking like a comfortable Rams spot. Allen has seven rushing touchdowns and has scored on the ground in every game this season. His ability to create outside structure gives Buffalo a path to stay in the game even if Los Angeles controls the matchup for long stretches.
Turnovers could decide it. Buffalo has given the ball away seven times across its last two games, with Allen involved in five of those giveaways, while Stafford has also thrown an interception in four straight games. One bad decision could swing both the scoreboard and the live contract prices.
The Rams have the stronger defensive profile, too. Los Angeles is allowing 145.5 passing yards per game, which could make it harder for Buffalo to keep pace solely through the air.
A final around Rams 31, Bills 27 fits the matchup.
Pick: Rams win by 4+ (48¢)
The outright Rams contract costs around 62¢, so the margin market offers a more aggressive price. At 48¢, the Rams win-by-4+ contract is close to a coin flip, while my projected score has Los Angeles clearing that threshold.
A $100 trade at 48¢ returns about $208 before fees if the Rams win by four or more.

The Kalshi promo code ACTION55 gives eligible new users $55 after completing $25 in qualifying trades, and Bills vs. Rams offers several Monday Night Football markets to consider immediately.
My preferred position is Rams win by 4+ at 48¢. Los Angeles has the more favorable defensive matchup, Stafford has multiple ways to attack Buffalo's secondary and the margin contract offers a lower entry price than paying 62¢ for the Rams outright.
