During the 2025-26 NBA season, Kalshi made waves by granting an equity stake to two-time league MVP Giannis Antetokounmpo. According to the Wall Street Journal, Sweeney’s representatives approached Novig to express interest as a potential investor. Eventually, the company granted her an undisclosed amount in equity. The increased role of celebrity endorsements in the space is a trend that will likely receive closer observation in the coming months.
During the second half of 2026, prediction markets have endured the wrath of a plethora of state governors, most notably Kathy Hochul of New York.
As the NFL season begins, a state in close proximity to the New England Patriots became the latest to attempt to curb the influence of the trading platforms. On 10 September, one day after the Pats’ season-opening loss to the Seattle Seahawks, Connecticut Governor Ned Lamont addressed the growth of the markets during a speech in downtown Hartford. On the same day, the Connecticut Department of Consumer Protection issued cease-and-desist orders to nine unregulated operators, including Polymarket, Robinhood and Underdog Predict.

Within a common area inside the Polymarket headquarters, Manning skied high to catch a ball from a jugs machine, while he withstood a low tackle from a defender. “Good morning, Eli,” James proclaimed, before the two-time Super Bowl MVP tossed him the football outside an elevator adorned with the Polymarket logo.

Last month, the Yankees became the first Major League Baseball club to directly partner with Polymarket.

Beyond director fees, Polymarket also had to budget for agency and concept fees, set construction and post-production costs that include visual effects, licensing and sound design. In late-August, Polymarket disclosed that it has sought a $21 billion valuation in a new funding round led by Donald Trump Jr’s venture firm, 1789 Capital.
Polymarket may defend any substantial investment in marketing given the overwhelming impact on customer acquisition that ensued. On Tuesday, Polymarket ranked first on the App Store in downloads for free finance apps, topping archrival Kalshi, Capital One Mobile and prominent payment providers PayPal and Venmo.

A similar scenario is playing out on the back of the MLB index introduction. Both LeagueShares and RexShares filed plans for ETFs tied to the FutureSports MLB indexes.
If approved, the funds would hold baskets of the CME-traded derivatives. LeagueShares went a step further by adding a filing for 2x leveraged MLB futures funds.
“Of course there’s already a filing for daily leveraged futures baseball ETFs — which are basically the equivalent of a corked bat with eight holes drilled in the handle that’s been dipped in pine tar,” wrote Ben Johnson, head of client solutions at Morningstar, on X.
