There’s nothing quite like a packed slate of baseball, and we’ve got a real chance to score a nice payday today. If you’re tired of the usual grind and want to try something fresh, we’re looking at the Kalshi promo code TSNEWS to get things started. Sign up here to claim a $10 bonus after making just $10 in trades.
| Kalshi Promo Code | TSNEWS |
|---|---|
| New User Offer | $10 sign-up bonus |
| Terms and Conditions | 18+ and Present in the US |
| Date Last Verified | March 26, 2026 |
What makes this setup different is that Kalshi operates as a financial exchange rather than a traditional sportsbook. That means it’s available to play in all 50 states. To get in on the action, new Kalshi customers just need to be 18 or older and make a first-time deposit of at least $1. Once your account is funded, simply make $10 in trades on their prediction markets—like forecasting tonight’s late-night showdown between the Cleveland Guardians and Seattle Mariners, or backing the Houston Astros against the Los Angeles Angels.
As soon as you cross that $10 trading threshold, your $10 bonus hits your account. We can then use that extra firepower on any of today’s matchups. Think the Tampa Bay Rays can handle the St. Louis Cardinals? Or maybe you’ve got a read on the Boston Red Sox visiting the Cincinnati Reds?
The board is wide open.

Best First Inning Bets for Today’s Slate
Let’s look at the available 1st Inning 3-way prediction markets for today’s slate. We’re looking strictly at the implied probabilities here to find our edge so you can deploy your sign-up bonus right from the first pitch:
| Matchup | Probability (1st Inning 1×2) |
|---|---|
| Rangers @ Phillies | PHI 25.5% / RAN 19.3% / Draw 55.2% |
| Red Sox @ Reds | RED 18.0% / SOX 25.6% / Draw 56.4% |
| Tigers @ Padres | PAD 18.6% / TIG 22.7% / Draw 58.7% |
| Angels @ Astros | AST 25.3% / ANG 18.9% / Draw 55.8% |
| Rays @ Cardinals | STL 21.2% / RAY 24.5% / Draw 54.2% |
| D-backs @ Dodgers | DOD 29.2% / DIA 18.7% / Draw 52.2% |
| Guardians @ Mariners | MAR 24.7% / GUA 16.9% / Draw 58.3% |
If we’re playing it safe and use a $10 trade on the heaviest favorite on the board—a scoreless first-inning draw between the Tigers and Padres (58.7% probability)—we’d secure a tidy $5.68 profit if successful. On the flip side, I’m always looking for a spot to swing for the fences. Backing the heaviest underdog, the Guardians, to win the first inning outright at a 16.9% probability would return a massive $44.30 profit on that same $10 trade.
That’s how we chase the big payouts.
The first inning is a fun way to stay engaged, but remember there are plenty of other markets, like which team will win the game and players to hit a home run.
World Series Futures Worth Considering
While we’re diving into today’s matchups, I always recommend keeping one eye on the bigger picture. You can absolutely use this time—and your newly unlocked bonus—to make predictions on which team will win the World Series. Forecasting the eventual champion right now is a great way to stay invested for the long haul and potentially line up a massive payout come October.
How to Claim Your $10 Kalshi Bonus
Unlocking this welcome offer is a breeze. Let’s get your account set up and ready before today’s first pitches are thrown. Here’s exactly how we’re going to do it:
- Create Your Account: Register for a new profile here using your standard personal information. You’ll also need to provide proof of identification during the verification process.

We don’t have to place a single $10 trade. An accumulated sum of $10 spread across multiple smaller trades is all it takes to satisfy the promotion’s terms.
