Kalshi promo – Kalshi says a new-user promo code, WTOP, can unlock a $10 bonus after a first-time $1 deposit and $10 in total trading volume on its prediction markets, including MLB games such as Yankees-Red Sox, Braves-Pirates, and Mets-Padres.
For anyone eyeing Saturday’s MLB slate, a new Kalshi offer is dangling a straightforward carrot: use the promo code WTOP, make a first-time deposit, and aim to build $10 in trading volume to trigger a $10 sign-up bonus.
Kalshi’s verified promo—dated June 6th, 2026—says it applies to new users who enter the code “WTOP” during sign-up. The offer is limited to people who are 18+ and present in the US, and it comes with a “$10 sign-up bonus” tied to how quickly a user reaches $10 in total trading volume.
The path, according to the terms laid out for the promotion, starts with a first-time deposit of at least $1. After that, the $10 bonus “unlocks immediately” once the user accumulates $10 in total trading volume, rather than requiring a single $10 transaction. The promo also emphasizes that Kalshi prediction markets are legally available in all 50 states.
Kalshi’s MLB slate examples for the offer include three matchups with probabilities listed for each side. In PIT @ ATL, the probabilities are ATL 56% / PIT 44%. In BOS @ NYY, New York is listed at NYY 54% / BOS 46%. And in NYM @ SD, San Diego is shown as SD 52% / NYM 48%.
The promotion leans heavily on baseball data to argue for where the “higher-probability investments” may be. In the AL East matchup between the New York Yankees and the Boston Red Sox. Kalshi points to the Yankees’ pitching staff suppressing runs with a 3.28 team ERA compared to Boston’s 3.85. It also cites lineup production, saying New York’s .761 team OPS stands apart from Boston’s .699. The promo claims the 62-point OPS gap translates to more consistent run production.
On the other side of the day’s slate. Kalshi frames the Atlanta Braves versus the visiting Pittsburgh Pirates as another matchup to watch. It cites pitching as the separation point, listing Atlanta’s 3.22 ERA against Pittsburgh’s 4.00. It then notes the offensive matchup is tighter. with Atlanta’s .757 team OPS compared with Pittsburgh’s .744. arguing those data points still favor Atlanta and New York as higher-probability investments.
If baseball isn’t the focus. the promo also points to an alternative prediction market tied to the Stanley Cup Final. Users who want to lock in their bonus are told they can trade $10 on Game 3 between the Hurricanes and Golden Knights “tonight.” Kalshi says the teams split the first two games in Carolina. and that the pivotal Game 3 will take place in Vegas.
Claiming the bonus. Kalshi lays out as a simple sequence: register a new account using standard personal details. enter the promo code WTOP during registration. make the first-time deposit of at least $1. and then execute $10 worth of trades—accumulated across multiple smaller predictions if needed—before the bonus automatically credits once the $10 threshold is reached.
The offer closes by reiterating that users can diversify across today’s MLB schedule, including forecasts such as the Pittsburgh Pirates at Atlanta Braves, the Boston Red Sox at New York Yankees, and the late-night West Coast matchup featuring the New York Mets at San Diego Padres.
