Kalshi Promo Code TSN15 Unlocks $15 Bonus for Dodgers-Mets, More MLB Prediction Markets

As a seasoned handicapper, I'm always searching for an edge, and today, that edge comes courtesy of an exclusive welcome offer. By using the Kalshi promo code TSN15, new customers can grab a $15 sign-up bonus here simply by putting down $10 in trades on the platform's prediction markets.

This bonus gives us instant value to tackle today's July 25 MLB matchups—or any other game on the diamond this weekend. We're in this together, so let's break down exactly how you can use this promo to chase a nice pay day.

Grab $15 Bonus with the Kalshi Promo Code TSN15

Before we dive into the trenches and start handicapping tonight's slate—including the powerhouse 65-win Los Angeles Dodgers taking on the New York Mets at Citi Field—let's look at the tale of the tape for this welcome offer:

If you're an eligible new Kalshi customer, this is your chance to claim a $15 sign-up bonus to use across today's exciting prediction markets. Whether you're keying in on the 61-win Atlanta Braves heading into Camden Yards to play the Baltimore Orioles, or keeping a close eye on the Chicago Cubs battling the Pittsburgh Pirates, this welcome offer is the easiest way to boost your bankroll. To get started, you just need to be a first-time user and make an initial deposit of at least $1.

Once your account is funded, the $15 bonus fully unlocks after you've made $10 in trades on Kalshi's prediction markets. The best part? Unlike some regional sportsbooks we've dealt with, Kalshi is available to players in all 50 states. As long as you are 18 or older, you've got a real chance to get in on the action from anywhere in the country.

Winning Probabilities on Saturday

To unlock that sweet Kalshi welcome bonus, we need to get $10 worth of trades down. If I'm playing it safe and placing my $10 trade on today's heaviest moneyline chalk—the Los Angeles Dodgers—a winning ticket nets a modest $6.33 profit. But if we're swinging for the fences and taking a shot on the slate's biggest underdog, the New York Mets, that same $10 trade yields a $13.20 profit.

Let's do a little handicapping for that marquee Dodgers-Mets clash. Looking at the numbers, LA holds a clear statistical advantage. The Dodgers' lineup has mashed its way to 539 runs and a .774 OPS, vastly outperforming the Mets' 421 runs and .686 OPS. On the mound, the Dodgers boast a 3.53 ERA, shutting down opposing lineups much more effectively than the Mets' staff and their 4.23 ERA. I'm placing my bets with the stats here.

Another premier interleague matchup I have my eye on features the Yankees visiting the Phillies. New York rolls into town with superior run production (481 runs and a .732 OPS) compared to Philadelphia (448 runs and a .702 OPS). The Bronx Bombers also boast a considerable edge on the rubber, flashing an impressive 3.35 team ERA against the Phillies' 4.23 ERA.

Guide for Using the Kalshi Promo Code

Getting set up and claiming this welcome offer is incredibly straightforward. I've been through the process, and if you follow these simple steps, you'll secure your $15 sign-up bonus well before tonight's first pitch:

1. Register Your Account: Create a new account here by entering your standard personal details. Because Kalshi runs a secure prediction market, you will also need to provide a quick proof of identification.
2. Enter the Promo Code: When prompted during sign-up, make sure you punch in the Kalshi promo code TSN15 to lock in the welcome offer.
3. Make a Deposit: Fund your new account with a first-time deposit of at least $1.
4. Place Your Trades: To fully activate the offer and see that $15 sign-up bonus hit your account, you must execute a total of $10 worth of trades on the platform.

Here is a pro tip from the trenches: you do not have to risk that $10 all on one single trade. You can split your risk however you see fit, provided the total sum of your wagers equals $10.

This kind of flexibility is a dream for tonight's diverse MLB slate. For example, I might place a few smaller trades on the high-profile pitching duel between Chicago's Shota Imanaga and Pittsburgh's Paul Skenes at PNC Park. After that, I'll use the rest of my required trading volume on the national FOX broadcast featuring the Dodgers and Mets. Once our total trades hit that $10 threshold, the $15 bonus automatically drops into our Kalshi account.
