Let's break down exactly how we're going to get this done. Eligible new customers have a real chance to pad their accounts right out of the gate. To trigger this $15 sign-up bonus, all you need to do is register and make a first-time deposit of at least $1. Once you're funded, we just need to place $10 in trades on Kalshi's prediction markets, and that $15 bonus is yours.


Whether you want to back the Los Angeles Dodgers against the New York Mets or dive into the prime-time showdown between the Yankees and Phillies, this is the perfect time to get some skin in the game. Kalshi is fully legal across all 50 states, so as long as you're 18 or older, we're good to go.

Probabilities for Sunday's MLB Games​

Matchup	Probability
ATL @ BAL	ATL 50.0% / BAL 50.0%
TOR @ BOS	TOR 44.6% / BOS 55.4%
LAD @ NYM	LAD 58.2% / NYM 41.8%
NYY @ PHI	NYY 37.5% / PHI 62.5%

When I'm handicapping a slate, I always look at the payouts. If we use $10 on today's heaviest favorite, the Philadelphia Phillies, a winning trade nets a safe but modest $5.32 profit for a total payout of $15.32. But we want to look for bigger value, right? If you back the biggest underdog on the board, the New York Yankees, a win returns a $15.50 profit, giving us an exciting $25.50 total payout.


To find a real edge, we have to dive into the stats. In that marquee NYY @ PHI contest, the Yankees (+155) look like a highly appealing underdog. Despite what the morning line says, New York holds a clear pitching advantage with a 3.35 team ERA compared to Philadelphia's 4.23 mark. Plus, the Yankees' bats have been hotter, pushing across 481 runs this season compared to the Phillies' 448. That's exactly the kind of value I love targeting.


Another great spot is the Los Angeles Dodgers visiting the New York Mets. The Dodgers are decisive favorites at -154, and their offensive numbers prove they deserve it. Los Angeles is swinging a heavy bat with a strong .260 team batting average and a .773 OPS. The Mets, meanwhile, are struggling at the dish, hitting just .233 with a .686 OPS. It's going to be tough for New York to keep pace, making the Dodgers a solid anchor for our trades.
