MLB Sponsorship Surge: Seven Teams Partner with Prediction Markets Like Kalshi

The intersection of professional sports and prediction markets reached a new peak in August 2026. A total of seven Major League Baseball franchises have now formalized official partnerships with platforms such as Kalshi, Novig, and Polymarket. On Tuesday, Kalshi announced new deals with five prominent teams: the Atlanta Braves, Boston Red Sox, Los Angeles Dodgers, San Diego Padres, and San Francisco Giants. They join the New York Mets and New York Yankees, who had previously blazed the trail with their own agreements. This gold rush is occurring precisely when the US Congress is demanding more stringent regulations on gambling promotion in sports.

This trend is no accident. Many organizations view partnerships with prediction markets similarly to those with traditional sports betting companies. It is about securing market share during a phase where capital is still flowing freely. There is a real explosion in spending, and once the race for customer acquisition cools down, much of this spending becomes nearly pointless. Since most customers only use one or two platforms, providers are investing heavily now to ensure they are among the favorites. For the teams, this translates into revenue that industry reports suggest can reach eight-figure sums per year.

Numbers and facts

The sheer scale of the financial involvement and the reach of these deals are significant. Kalshi is reportedly in talks for a league-level deal with the entire MLB. The New York Mets were pioneers, becoming the first club to sign a deal with Novig. Lew Sherr, president of business operations for the Mets, commented:

"We were well aware of the process happening at the league level. When the opportunity presented itself, we were well prepared to act on it." - Lew Sherr, President of Business Operations, New York Mets

In addition to fixed sponsorship fees, providers entice users with extreme promotions. Kalshi, for instance, generated headlines with a bracket contest offering a one-billion-dollar grand prize for a perfect prediction of all 63 games in the men's college basketball tournament. According to Kalshi's calculations, the odds of winning this prize are approximately 1 in 120 billion. To hit those odds statistically, one would need to fill out a bracket every second for about 3,800 years. Nevertheless, such advertising keeps the brand in the conversation, even as the NCAA continues to distance itself from any gambling association.

Background

What do prediction markets hope to gain from these expensive engagements? The primary goal is legitimacy. At a time when many of these platforms are in a legal limbo and judges are often unconvinced that they represent something other than gambling, the logo of a storied baseball team acts as a seal of approval. Furthermore, providers gain access to exclusive fan experiences for their VIP clients. This includes batting practice at Yankee Stadium or meet-and-greets with retired players.

Integrity remains a critical concern. Insider trading and manipulation are constant companions of this emerging industry. Following the suspensions of Emmanuel Clase and Luis Ortiz last summer, the MLB took steps to limit or cap betting amounts on specific outcomes, such as the result of individual pitches. Ari Borod of Polymarket emphasized that the agreement with the MLB includes an integrity framework that restricts markets more vulnerable to manipulation by managers or umpires.

Why it matters for German players

For German baseball fans and sports bettors, these developments in the US are interesting but legally distant. The German market is strictly regulated by the State Treaty on Gambling 2021 (GlüStV 2021). While eight-figure sponsorship deals with young prediction markets are celebrated in the US, the Joint Gambling Authority of the States (GGL) maintains a tight framework here. German players must adhere to a monthly deposit limit of 1,000 euros, monitored across all providers via the LUGAS system.

Prediction markets like Kalshi or Polymarket do not currently hold a German license for sports betting or virtual slots. Anyone in Germany wishing to bet on MLB games must choose a provider listed on the official GGL whitelist. Only there are player protection measures, such as the 1-euro limit per spin for slots or the connection to the OASIS lockout file, guaranteed. US models where VIPs are lured with field access are hardly compatible with strict German advertising guidelines designed to minimize incentives for participation.

What it means for GGL-licensed casinos

For casinos and betting providers with a GGL license, the US trend primarily signals a need for vigilance. While the line between entertainment, prediction, and hard gambling blurs in America, the distinction remains sharp in Germany. German providers may only offer MLB bets within the scope of permitted markets. Bets on micro-events like the next pitch, which led to manipulation allegations in the US, are either strictly regulated or prohibited in Germany to protect sports integrity. German licensees benefit from legal certainty but must act far more cautiously in their marketing than their US counterparts.
