WNBA ‘Slips Up’ Again as Reese-Bueckers Betting Video Surfaces Amid Big Week for Prediction Markets

The WNBA found itself at the center of an avoidable gambling controversy this week after its own official social media account posted — then quickly deleted — a video showing Atlanta Dream star Angel Reese and Dallas Wings guard Paige Bueckers discussing a $400 personal wager on the outcome of their teams’ matchup. The clip, recorded during All-Star weekend practice in Chicago, surfaced again on the league’s account just hours before Atlanta and Dallas tipped off on Wednesday night, and it was live long enough for fans to capture and recirculate it widely across social media.

The timing could not have been worse. The episode landed in the same week that the broader prediction markets industry was consumed by two much larger stories: the Commodity Futures Trading Commission’s proposal to rein in vertically integrated exchanges and market makers, and British trading firm IG Group’s roughly $1.3 billion agreement to acquire Underdog, one of the fastest-growing operators in the prediction markets space.

A Self-Inflicted Wound for the WNBA

In the video, Reese can be heard telling Bueckers, “If you win, you get the $400,” with Bueckers responding, “If we lose, then you keep it.” The league’s caption framed the exchange as lighthearted, quoting Bueckers joking “We did?” when asked about the bet on camera. But the WNBA’s own collective bargaining agreement leaves no ambiguity on the subject. Under Article XIV, Section 5(c), any player found to have wagered — directly or indirectly — on the outcome, score, or any other aspect of a WNBA game is subject to fines, suspension, or even dismissal from the league at the commissioner’s discretion.

The Dream went on to beat the Wings 82-81, with Reese finishing the night with 22 points and 12 rebounds. A league spokesperson acknowledged Thursday that the post “missed the mark,” stating that players undergo annual training on the league’s anti-wagering rules and that the situation was being “addressed internally.” According to a person with direct knowledge of the matter, no discipline is expected for Reese or Bueckers, though the episode has renewed scrutiny of how closely leagues monitor their own social media teams for integrity-related missteps — the very risk that sportsbooks and sports betting operators are increasingly forced to account for as player-facing content becomes more casual and bet-adjacent.

It is not the first time this year that WNBA ownership or personnel have drawn scrutiny for gambling-adjacent activity. Earlier this basketball season, the NBA confirmed it was reviewing a minority ownership stake held by Minnesota Timberwolves and Lynx owners Marc Lore and Alex Rodriguez in Mojo Interactive, a startup trading sports outcomes on the prediction market exchange Kalshi. The league maintains that team and league personnel are barred from trading on NBA or WNBA contracts on any prediction market platform, and said it was reviewing the Lore-Rodriguez arrangement to confirm compliance. Taken together, the incidents paint a picture of a league still working out how to police the intersection of ownership, players, and the fast-expanding world of sports wagering and prediction markets.

CFTC Eyes Market Maker Conflicts as Underdog Cashes Out

The WNBA misstep played out alongside what several outlets are calling the biggest week yet for prediction markets regulation and consolidation. The CFTC is proposing new rules targeting potential conflicts of interest at vertically integrated exchanges — platforms that also own their in-house market makers. Under the proposal, those market makers could still operate, but would lose the ability to take directional positions on markets, instead being required to provide liquidity on both sides of a trade as neutral participants. Analysts note the rule could reshape the economics for several major players, including Kalshi, which owns market maker Kalshi Trading, and the Robinhood-Susquehanna joint venture Rothera.

Separately, IG Group announced it has agreed to acquire Underdog in a deal valued at up to $1.3 billion — roughly $1.1 billion upfront with a $200 million earnout tied to performance targets. Underdog, which became the first major U.S. sports betting operator to pivot toward prediction markets, has been aggressively expanding its own exchange, reportedly topping $1 million in single-day trading volume within ten days of launch. The deal is expected to significantly grow IG’s U.S. footprint, adding close to a million monthly active users and a younger, mobile-first customer base to the London-based fintech firm’s existing trading infrastructure.

Together, the two storylines underscore how fast the prediction markets sector is evolving — and how exposed sports leagues remain to integrity headaches, whether from regulatory uncertainty at the exchange level or from something as simple as a poorly considered social media post about a friendly wager between teammates turned opponents.
