The Kalshi sign-up bonus applies across the platform, so your qualifying $25 goes straight into Rays vs. Yankees at 7:05 p.m. ET or Padres vs. Dodgers at 10:10 p.m. ET. New users who register with Kalshi promo code ACTION55 trade $25 and collect a $55 bonus, and the timing lines up with the best two-game stretch of the regular season's final week.
Tampa Bay lands in the Bronx with a magic number of two, so the Rays clinch the AL East and the league's top seed with one more win behind Drew Rasmussen against Max Fried. New York sits six games back and out of the division race, yet the Yankees still own the majors' best team ERA and plenty of reasons to spoil the party in front of a hostile crowd. Out West, Yoshinobu Yamamoto takes the mound for a Dodgers team two games behind Milwaukee for the National League's top seed, opposite a Padres club fighting the Cubs for home field in the Wild Card Series. Four playoff teams, three races still open, and both games on one channel.
Kalshi operates as a CFTC-regulated prediction market, so you buy yes-or-no contracts priced in cents instead of backing a traditional number. That extra $55 gives you real ammunition for two games that decide playoff seeding.

Kalshi MLB Odds on TBS: Rays vs. Yankees, Padres vs. Dodgers
TBS stacks both games back-to-back, and the early pricing sits tighter than the standings suggest. Doubleheader markets post late and swing hard once lineups drop, so treat the board below as a Monday snapshot and confirm before you buy. Prediction markets already price the Bronx nightcap close to a coin flip.
Rays vs. Yankees
| Market | Tampa Bay Rays | New York Yankees |
|---|---|---|
| Moneyline | 44% | 56% |
| Run Line | +1.5 (65%) | -1.5 (36%) |
| Total | Over 6.5 Runs (52%) | Under 6.5 Runs.5(48%) |
First pitch for Rays vs. Yankees is at 7:05 p.m. ET on Tuesday, September 22, 2026. Always check Kalshi for the most up-to-date pricing before the game begins.
Tampa Bay needs two wins to lock the AL East and the league's top seed, and the Rays send out their most reliable arm to get one. Drew Rasmussen carries a 15-5 record, a 2.72 ERA and a 0.93 WHIP into Yankee Stadium, and he shut the Yankees down in April, allowing one hit across six scoreless innings. New York owns the better staff on paper, but the Yankees have dropped two straight and Aaron Judge is nursing lower-leg tightness with a wild-card berth already banked. Trent Grisham also drew a Grade 2 hamstring diagnosis, and Jazz Chisholm sits on the IL with a thumb sprain, which thins a lineup that lives on damage. Add the majors' lowest staff WHIP at 1.13 and a Tampa Bay lineup that strikes out less than any other, and a plus-money dog with everything to play for reads like the better side.
Rays vs. Yankees Prediction: Rays Moneyline (44%)
Padres vs. Dodgers
| Market | San Diego Padres | Los Angeles Dodgers |
|---|---|---|
| Moneyline | 43% | 57% |
| Run Line | +1.5 (42%) | -1.5 (58%) |
| Total | Over 6.5 Runs (48%) | Under 6.5 Runs (52%) |
First pitch for Padres vs. Dodgers is at 10:10 p.m. ET on Tuesday, September 22, 2026. Always check Kalshi for the most up-to-date pricing before the game begins.
Los Angeles hands the ball to Yoshinobu Yamamoto, and his 2.51 ERA and 0.87 WHIP dwarf what Michael King brings across the diamond. The Dodgers sit 96-60, go 50-28 at home and trail Milwaukee by two games for the National League's top seed, so motivation stays intact. San Diego arrives hot, but the Padres are 28-41 against teams at .500 or better and are 38-40 on the road, and Los Angeles has taken five of seven meetings this season. Paying a short moneyline price makes little sense here. Instead, take the run line at plus money and let Yamamoto plus a rested bullpen build a cushion.
Padres vs. Dodgers Prediction: Dodgers -1.5 (58%)
