Philadelphia Eagles running back Saquon Barkley says he sold his ownership stake in prediction-market company Polymarket because NFL rules do not allow players to invest in or promote companies like it. The story, first reported by Front Office Sports on Wednesday, October 28, 2026, has put a spotlight on a growing split in American sports: while the NBA, Major League Baseball, the NHL and Major League Soccer have all struck deals with prediction-market companies, the NFL is still saying no.
What we know / What we don’t know
What we know:
- Barkley told Front Office Sports he used to hold equity in Polymarket and no longer does. “I am not in that right now,” he said. “I am not allowed to be in that.”
- The NFL confirmed to Front Office Sports on Wednesday that its ban on players investing in or promoting sportsbooks also applies to prediction markets.
- Barkley’s investment first became public in a profile published in September 2025, alongside stakes in several technology startups.
- The NFL Players Association said in January 2026 that the league views prediction markets as gambling entities, so players cannot endorse companies such as Kalshi or Polymarket.
- The NBA, MLB, NHL and MLS all have partnerships with Polymarket, Kalshi, or both.
What we don’t know:
- The NFL declined to comment on Barkley’s specific situation, so the league has not publicly confirmed the details of his individual case.
- Polymarket declined to comment for the Front Office Sports story.
- Barkley did not say when exactly he sold, how much his stake was worth, or whether he made or lost money on it.
- It is not yet clear whether the NFL’s rules for team owners holding stakes in prediction-market companies match the rules for players. NBC Sports has asked the league that question and, as of this writing, it remains open.
What happened
Barkley explained the situation in simple terms. Before every season, the NFL briefs players on what they can and cannot do when it comes to endorsements, investments and other off-field business. Prediction markets were among the areas covered this year. Once the league made clear that players cannot have financial interests in prediction-market platforms, Barkley got out. The account of his sale comes from Barkley himself; the league confirmed the general rule but declined to discuss his case specifically, and no outlet has reported a correction or denial.
“So I kinda had to get out of that,” he told Front Office Sports. “I was in it before, but no bueno.”
That short quote is doing a lot of work. Barkley bought in before the rule changed for players. His stake was public knowledge more than a year ago, when it appeared in a profile of his startup investments in September 2025. At some point between that profile and the summer of 2026, the league told players that financial interests in prediction-market platforms were off limits.
What is a prediction market, anyway?
If you have never used one, the idea is simple. A prediction market lets people trade contracts tied to the outcome of a future event. The contracts usually work like yes-or-no questions: will this team win, will this event happen, will this number go up or down. If you are right, the contract pays out. If you are wrong, it does not.
That is why the NFL treats these platforms the way it treats sportsbooks. From the league’s point of view, a contract on the outcome of a football game looks and acts a lot like a bet on that game, even if the platform calls it something else. The league’s worry is straightforward: it does not want its own players holding a financial interest in companies that make money from trading on games, including games those players might play in.
Prediction-market companies see it differently. They argue their contracts are financial products, more like trading on a stock exchange than placing a bet at a sportsbook, and that they should be regulated at the federal level. That disagreement is now heading toward the courts, which brings us to the bigger fight behind Barkley’s story.
A rule that has been tightening for more than a year
Barkley’s exit did not come out of nowhere. The NFL’s position has been hardening in public steps:
- August 2025: The league told players it would treat prediction markets the same as sports betting, according to Sports Business Journal reporting at the time. The league’s chief compliance officer said these platforms “mimic sports betting” and fall under the policy against gambling.
- January 2026: An NFL Players Association spokesperson told Front Office Sports that the league “views prediction markets as gambling entities, so players are not allowed to be an endorser or brand ambassador for a company like Kalshi or Polymarket under the gambling policy.”
- 2025 season: The NFL barred prediction-market advertising, including during the Super Bowl.
- October 2026: Earlier this month, the league asked the U.S. Supreme Court to consider a New Jersey case that could decide whether federal commodities regulation or state gambling laws govern sports event contracts. The NFL’s position is that these contracts should be regulated at the state level.
- October 28, 2026: The NFL confirmed to Front Office Sports that the ban on players investing in or promoting sportsbooks extends to prediction markets.
Put together, that timeline explains why a stake Barkley could openly hold in 2025 had to go in 2026.
The NFL is now the odd one out
Here is what makes this story bigger than one player’s portfolio. Every other major American sports league has gone the other direction:
- The NHL was first, announcing deals with Kalshi and Polymarket in October 2025.
- MLS announced an agreement with Polymarket in January 2026.
- MLB reached an exclusive deal with Polymarket in March 2026, reported by Front Office Sports to be worth up to $300 million over four years.
- The NBA announced Kalshi and Polymarket as its “preferred prediction market partners” just this week. That deal does not apply to the WNBA.
The NBA’s approach also shows how differently leagues handle their own players. NBA players are not barred from endorsing or investing in prediction markets in general, though they cannot promote contracts tied to NBA games. LeBron James, for example, has a reported $15 million per year endorsement deal with Polymarket, focused on promoting football, according to Front Office Sports. Giannis Antetokounmpo is an investor in Kalshi.
In other words, the same kind of deal that is a headline partnership in the NBA is a rule violation for an active NFL player.
Players vs. owners: a question that is still open
There is one more wrinkle, raised by NBC Sports’ ProFootballTalk. The NFL has previously said team owners may own up to five percent of a company that operates a sportsbook, as long as the owner is not involved in running the wagering operation. The league does not disclose which owners hold such stakes.
NBC Sports has asked whether the same allowance applies to owners holding stakes in prediction markets. If owners can hold small stakes while players cannot hold any, that would be a sharp double standard. For now, that question has no public answer.
Why this matters to regular fans
You do not need to care about Barkley’s investments to care about this story. Three things about it touch ordinary fans directly.
First, it affects what you see. The NFL has kept prediction-market ads out of its broadcasts, including the Super Bowl, while other leagues’ games and broadcasts are full of them.
Second, it affects the legal fight over how sports trading is regulated in America. If the Supreme Court takes the New Jersey case the NFL is pushing, the ruling could decide whether sports event contracts are treated like bets under state law or like financial products under federal law.
Third, it is a reminder of how fast this world is changing. Prediction markets barely registered with most sports fans a few years ago. Now they sponsor leagues, sign superstar endorsers, and force a star running back to sell a stake he once disclosed in public.
What to watch next
- The Supreme Court: Will the court take up the New Jersey case on sports event contracts, and if so, which way does it lean, state regulation or federal commodities law?
- The owners question: Will the NFL answer whether owners may hold prediction-market stakes under the same kind of allowance that applies to sportsbooks?
- Other NFL players: Barkley is the first big name to speak publicly about divesting, but he is unlikely to be the only player who held such a stake.
- The Eagles on the field: None of this changes Barkley’s status as a player. The story is about an investment, not about his availability for games. Follow our latest sports coverage for more.
The bottom line
Saquon Barkley says he sold his Polymarket stake because the NFL told players they cannot invest in prediction-market companies. The league has confirmed the rule in general, while declining to discuss his case in particular. The other major leagues have embraced the very companies the NFL is keeping at arm’s length. And a Supreme Court case could soon decide the legal question underneath it all: are sports event contracts gambling, or are they something else entirely?
