Saquon Barkley Forced to Sell Polymarket Stake Under NFL Rules

Philadelphia Eagles running back Saquon Barkley has revealed that the NFL forced him to sell his ownership stake in Polymarket, as the league continues to distance itself from prediction-market platforms.

Speaking to Front Office Sports in an interview published October 28, Barkley confirmed that he was no longer involved with the company after learning that NFL rules prohibit players from investing in or promoting prediction markets.

"I was in it before, but no bueno," Barkley told Front Office Sports.

Barkley's investment had previously been reported in September 2025, although the exact size of his stake and the financial details of its sale remain undisclosed. He had already exited the company before the interview was published.

Why Did Barkley Have to Sell His Polymarket Stake?

The NFL prohibits active players from investing in or endorsing gambling companies, and those restrictions also apply to prediction-market operators such as Kalshi and Polymarket.

The league confirmed that policy following Barkley's comments but declined to address his individual situation.

Barkley explained that players receive guidance before each season about permitted investments, endorsements and other commercial activities. His Polymarket investment ultimately fell outside those rules.

Interestingly, the NFL already maintains commercial relationships with traditional sportsbooks, including DraftKings, FanDuel and Fanatics. However, those league-level agreements don't give individual players permission to invest in gambling-related companies.

For now, the NFL is treating prediction markets much the same way.

NFL Takes a Different Approach From the NBA and NHL

Barkley's situation comes at an interesting time for the prediction-market industry.

The NHL signed official partnerships with Kalshi and Polymarket in October 2025, while Major League Baseball and MLS have since established their own agreements with Polymarket.

More recently, the NBA announced partnerships with Kalshi and Polymarket, naming both companies its Preferred Prediction Market Exchanges.

The agreements give the platforms access to official league data, branding and marketing opportunities, while introducing safeguards designed to protect the integrity of NBA games.

The NFL, meanwhile, remains the most prominent holdout among America's major professional sports leagues.

That doesn't mean football fans cannot access NFL prediction markets. Both Kalshi and Polymarket offer contracts covering NFL games and player performances where permitted. The disagreement concerns the league's willingness to formally embrace these companies and the regulatory framework governing their products.

Celebrity Partnerships Come With Complications

Barkley's departure comes as prediction-market companies increasingly turn to famous athletes and entertainers to promote their platforms.

LeBron James has appeared in Polymarket campaigns, while Kalshi has worked with Lionel Messi and other prominent athletes. As we explored in our article on celebrities promoting prediction markets, major names have become an important part of the industry's push toward mainstream audiences.

Barkley's situation highlights the other side of that strategy. Celebrity partnerships may bring attention and credibility, but professional sports leagues still have the final say over which commercial relationships their players can pursue.

Could the NFL Change Its Position?

There's little indication that the NFL intends to follow the NBA and NHL anytime soon.

Earlier in October, the league supported a request for the U.S. Supreme Court to examine whether sports-related prediction markets should fall under federal or state regulatory authority.

The NFL has also raised concerns about market manipulation, insider trading and whether the Commodity Futures Trading Commission has sufficient resources to oversee sports contracts.

Those are legitimate questions, particularly as prediction markets expand into increasingly specific player-performance contracts.

Still, the contrast is becoming difficult to ignore. Other major leagues are signing commercial agreements with prediction-market operators, while the NFL continues to keep them at arm's length.

Barkley's forced exit is another example of that divide.

And with prediction markets becoming increasingly prominent across American sports, the question isn't simply whether the NFL will eventually embrace them. It's whether the league can maintain its current position as the rest of the industry moves in a different direction.
