The New York Yankees and Polymarket announced a partnership on Thursday, designating the platform as the team's official prediction market partner for the remainder of the season.

Polymarket, a decentralized prediction market built on the Polygon blockchain where users trade shares on the outcomes of real-world events, has been rapidly expanding its presence in professional sports through league-level deals.

"We are excited to begin a relationship with Polymarket — Major League Baseball's prediction market partner," said Yankees Senior Vice President of Partnerships Michael Tusiani in a release. "Through signage and fan experience opportunities, we look forward to elevating Polymarket's brand awareness both at Yankee Stadium and across our fan base."

Polymarket's President of Sports Business Development Ari Borod added: "We are proud to become an Official Prediction Market Partner of the New York Yankees. Yankees fans are among the most active on our platform and passionate in sports, and Yankee Stadium is a natural home for Polymarket, where the questions driving our markets come to life throughout the season."

Under the sponsorship agreement, Polymarket will maintain a visible presence at Yankee Stadium as well as during Yankees broadcasts on the YES Network and Amazon Prime Video. The sponsorship package also includes Polymarket's purchase of tickets to premium hospitality areas and suites. Fans will gain access to exclusive experiences, including an outfield catch event for children, Kids Run the Bases, and lineup card delivery opportunities.

The Yankees become only the second franchise across North America's four major sports leagues to establish a partnership with Polymarket, following the NHL's New York Rangers. Polymarket also serves as Major League Baseball's exclusive Prediction Market Exchange partner and holds the title of official prediction market partner for the National Hockey League. The agreements follow a broader pattern of blockchain-based platforms securing major sports sponsorships to build mainstream brand recognition, a strategy previously pursued by Crypto.com and, before its collapse, FTX.

Polymarket has also faced regulatory scrutiny. In 2022, the Commodity Futures Trading Commission (CFTC) ordered the platform to pay a civil monetary penalty and cease offering certain markets after finding it had operated an unregistered trading facility.

According to Polymarket's own markets, the Yankees are given a 97% probability of missing the postseason. The team has faced offensive challenges in the absence of Aaron Judge, with Giancarlo Stanton and Cody Bellinger also sidelined by injuries. However, the pitching staff has performed strongly, and reinforcements acquired at the trade deadline are expected to bolster the roster as the Yankees pursue their first World Series title since 2009.
