Kalshi Sign Up Bonus: Use Code ACTION55 to Unlock $55 Bonus for Bills vs. Vikings on MNF

New traders who want the Kalshi sign up bonus need the promo code ACTION55, which turns a $25 trade into $55 in bonuses before Bills vs. Vikings kicks off tonight at 8:15 p.m. ET on ABC and ESPN. Sign-up takes under 3 minutes, and the bonus pays win or lose.

The 6-1 Bills visit the 6-1 Vikings in NFL Week 9 at U.S. Bank Stadium. Buffalo rides a three-game win streak after a 36-10 rout of Baltimore, while Minnesota chases a bounce-back from its first loss with Carson Wentz at quarterback, because Kyler Murray sits out with a hamstring strain. The Bills’ No. 1 offense meets the Vikings’ No. 1 defense, and that $55 bonus funds a front-row seat.

What does the Kalshi sign up bonus offer for MNF?

Kalshi prices read in cents, and each price doubles as a chance. A winning contract pays $1.00, and a miss pays $0, so your loss never exceeds the price you pay. Prices move before kickoff, so confirm them in the app.

On the spread, Yes backs Buffalo to win by four or more, while No backs Minnesota to win or lose by three or fewer. The total works the same way around 44.5 points.

Buffalo holds the AFC’s best record after beating Baltimore 36-10 for its third straight win, while Minnesota suffered its first loss of the season, 19-15 at Detroit. The Vikings lead the series 9-6, but the teams have not met in a non-Sunday game since 1982, when Buffalo won 23-22.

The matchup pits the league’s best offense against its best defense. The Bills score 33.3 points per game, and the Vikings allow just 13.2 while leading the NFL with 25 sacks. Coordinator Brian Flores blitzes on 73% of snaps, and he sent extra rushers on 26 of Jared Goff’s 29 dropbacks last week. Josh Allen answers well against pressure, completing 66% of his passes against the blitz this season at 8.4 yards per attempt.

Minnesota’s offense faces a tougher job, ranking 30th in EPA per play and scoring only 15 points at Detroit. Wentz started the Vikings’ 9-3 win at Chicago in Week 2, and he takes over for Murray here. Buffalo’s defense has tightened under coordinator Jim Leonhard, holding its last two opponents to completion rates of 56% and 46%. The Under is 6-1 in Vikings games, which explains why Kalshi prices the 44.5 total as a coin flip.

How to Unlock the Kalshi Sign Up Bonus on Bills vs. Vikings?

The bonus needs $25 in trades on any market, win or lose. These three trades total exactly $25 and spread your risk across a touchdown, a catch total and a run total:

Bills vs Vikings Trade 1: Justin Jefferson 1+ touchdowns (Yes, 38¢, $10)

• Four touchdowns in six games beats the 40% chance Kalshi gives him.
• He led Minnesota with nine targets at Detroit and still scored.
• A Buffalo lead forces Wentz to throw, and Jefferson draws the most looks.

Bills vs Vikings Trade 2: Jordan Addison 40+ receiving yards (Yes, 50¢, $10)

• He led Minnesota with 66 yards on eight targets at Detroit.
• Jauan Jennings ran only 20 routes on 33 dropbacks, so Addison and Jefferson own the passing game.
• If Buffalo takes away Jefferson, the targets shift to Addison.

Bills vs Vikings Trade 3: Josh Allen 40+ rushing yards (Yes, 37¢, $5)

• He has 270 rushing yards through seven games, about 39 a game, so 40 sits right at his average.
• Nine rushing touchdowns show Buffalo trusts his legs near the goal line.
• Minnesota’s blitz-heavy scheme puts seven or eight defenders at the line, which opens lanes when he scrambles.

If all three hit, the max payouts total $57.44 on $25 staked. Prefer game lines? Swap in Buffalo to win at 63¢ or Over 44.5 at 51¢. Any mix totaling $25 counts, and Kalshi credits your $55 once the trades settle. Trade only what you feel comfortable losing.
