LeBron James officially partnered with Polymarket over Labor Day Weekend, marking a significant shift in the prediction market landscape. On the same day that Ohio State University took the field for their college football season opener, James revealed this collaboration through a video on social media platform X. As fans watched Ohio State demolish Miami (Ohio) with a score of 56-3, industry insiders speculated about which other athletes might join James in promoting Polymarket.
By the following Tuesday, Polymarket unveiled its ad featuring James, which quickly drew 15.5 million views on his X page. The advertisement debuted just after the three-day Labor Day Weekend, showcasing a vibrant 90-second commercial directed by Peter Berg, known for the celebrated series Friday Night Lights. The ad highlighted several celebrities, including Eli Manning, Derek Jeter, Richard Sherman, John Leguizamo, and Spike Lee, and coincided with the introduction of Squads—a new feature in the Polymarket app designed for users to discuss markets, share predictions, and engage in trading.
Travis VanderZanden, Polymarket's chief growth officer, emphasized the need for a communal space where users can exchange bets and predictions. "People are constantly debating what’s going to happen next with their friends and sharing predictions in group chats. With Squads, we’re bringing the conversation and trading together so friends can follow the events they care about and make their predictions in one place," VanderZanden stated.
The ad featured humor reminiscent of iconic Nike commercials from the 1990s as well as a playful take seen in an NFL spot during Super Bowl LIII. In one scene, Manning leaps to catch a ball from a JUGS machine while enduring a mock tackle. The encounter highlights James, who exchanges greetings with Manning and a handshake with Jeter outside a Polymarket-branded elevator. Notably, the New York Yankees recently became the first Major League Baseball team to directly partner with Polymarket.
While Polymarket has not disclosed the ad's financial details, estimates suggest production costs likely reached into the millions, given the involvement of a high-profile director and the expenses associated with agency fees, set construction, and post-production efforts. In late August, the company indicated it was seeking a $21 billion valuation in a funding round led by Donald Trump Jr.'s venture firm, 1789 Capital.
This substantial advertising push appears to be effective for user acquisition, as Polymarket clinched the top spot in App Store downloads for free finance apps, surpassing its competitor Kalshi as well as financial giants Capital One Mobile, PayPal, and Venmo.
However, not everyone is in favor of this initiative. Critics, particularly anti-gambling advocates, raised concerns regarding the promotion of Polymarket. Craig Carton, a host at WFAN 660 AM and a recovering compulsive gambler, criticized the athletes endorsing the platform, suggesting that unregulated markets are harmful and could lead to financial ruin for participants. He highlighted the difference between regulated sportsbooks that prohibit underage betting and prediction markets that allow younger users between 18 and 21 years old. Carton questioned the ethics of the sports figures and their endorsements, stating, "At what point does someone come along where you say no to the offer?"
A Bank of America study published on September 1 indicated that households participating in online betting have a median deposit account balance 59% higher than non-participants, adding to the debate around the blending of entertainment and investment as prediction markets grow alongside traditional sports betting.
Complicating matters is the ongoing struggle between advocates for state rights and those pushing for federal regulation over sports trading, with Carton labeling the trading of sports-event contracts as unregulated gambling. Prediction markets, referred to as Designated Contracts Markets, are overseen at the federal level by the Commodity Futures Trading Commission (CFTC).
Recently, a CFTC deputy general counsel advertised a senior position, hinting that the commission is crafting formal rules for event contracts, a regulation described as potentially groundbreaking in the agency's history.
Polymarket's ad campaign coincided with the NFL's regular-season opener on Wednesday, which featured a rematch between the Seattle Seahawks and the New England Patriots, following last year’s Super Bowl encounter where the Seahawks triumphed 29-13. Current market odds on Polymarket show a 62% chance for the Seahawks to win against the Patriots, who sit at 39%, reflecting a payout structure that could offer investors a $247.35 return on a $100 bet on New England.
James’ prior multi-year deal with DraftKings lapsed earlier this summer, according to reports from Yahoo Finance.
