Kalshi promo – A new Kalshi welcome offer lets eligible U.S. users use the promo code WTOP during registration to earn a $10 sign-up bonus after making a first-time deposit of at least $1 and completing $10 in trades, with MLB prediction markets highlighted for Wednesday, Ma
On a day when baseball fans are already scanning probable pitchers and lineup notes, a different kind of wagering buzz is circulating online: a Kalshi welcome offer tied to MLB prediction markets.
New users can claim a $10 sign-up bonus by entering the promo code WTOP during registration. The offer is designed for people who are 18 and older and present in the US, and it’s verified as of May 27, 2026.
The steps are straightforward. Users download the Kalshi app. register a new profile by providing standard personal information. and submit valid proof of identification as part of onboarding. During registration, they enter the promo code WTOP, then make a first-time deposit of at least $1. The bonus unlocks after they execute a total of $10 worth of trades on the platform’s prediction markets.
Kalshi’s promotion also comes with a practical caveat: you don’t have to risk the full $10 on a single prediction. The guidance provided to new customers suggests splitting initial capital across multiple smaller trades as long as the cumulative trading volume reaches $10.
The timing matters for anyone looking to act immediately. The offer is available across all 50 states, and it’s framed around Wednesday’s May 27, 2026 MLB slate, including matchups involving the St. Louis Cardinals, Milwaukee Brewers, Philadelphia Phillies, and San Diego Padres.
One highlighted market centers on PHI @ SD, where Kalshi’s listed probabilities show 58.3% on one side and 41.7% on the other for Wednesday, May 27, 2026.
The matchup is described as a pitching duel featuring Cristopher Sánchez for the Phillies against Walker Buehler for the Padres. San Diego is presented as holding an edge on the mound with a collective 3.84 ERA and 1.25 WHIP. while Philadelphia is listed with a 4.06 ERA and 1.32 WHIP—factors the promotion says help limit basepath traffic compared to Philadelphia.
Still, the promotion leans on Philadelphia’s offense to keep those probabilities elevated. Philadelphia is listed with a .384 slugging percentage and a .681 OPS, narrowly ahead of San Diego’s .363 slugging mark and .657 OPS.
The offer also points to other possible markets for the same day, including whether the Cardinals can topple the Brewers, and it names the Phillies and Padres matchup as part of how users can put the bonus capital to work in prediction markets tied to baseball results.
At the end of the process, the structure is the same: once a user completes $10 in trades, the $10 bonus is credited to their account. From there, the promotion suggests using the extra funds to make additional predictions across the Wednesday slate.

So basically free $10 if you “trade” baseball stuff? Sounds too good.
I don’t even get the Kalshi part. Like do you have to bet on the Phillies game or can it be any MLB market? Also $1 deposit then $10 in trades… that’s a lot of steps for $10.
Wait, the article says PHI @ SD is like 58.3% and 41.7%… so does that mean SD wins 41.7% of the time?? That feels backwards. And what counts as “$10 worth of trades” like just placing bets or actually winning?
I’m seeing people say this is a promo code WTOP but I swear I saw another one last year and it was fake. Also “verified as of May 27, 2026” like okay cool but is this available in every state for real? I’m not trying to do all that ID proof for $10.
