The prediction markets sector has had a particularly eventful week, with numerous significant developments making headlines. Notable among these is the push from gaming regulators globally for the Supreme Court to take up New Jersey's case against Kalshi, a move echoed by the NFL and 39 states in separate legal filings.
Compounding this legal pressure, Florida's Seminole Tribe has initiated a lawsuit against DraftKings over its prediction platform.
In another pivotal development, four additional Indian tribes in California and Oklahoma have entered into agreements with Kalshi to launch their own prediction market apps. These tribes include the Alabama-Quassarte Tribal Town from Oklahoma, and the Alturas Indian Rancheria, Greenville Rancheria, and Kletsel Dehe Wintun Nation from California. This follows Kalshi's earlier partnership with the Tunica-Biloxi Tribe of Louisiana.
Kalshi's CEO, Tarek Mansour, expressed optimism about these partnerships, stating, “More tribes are recognizing that federally regulated prediction markets offer a real path to new, sustainable revenue. Prediction markets and Tribal economic development don’t have to be at odds. They can grow together… The future of this industry doesn’t have to be organized around conflict. It can be organized around opportunity, with Tribal nations participating as owners and helping shape what it becomes.”
Historically, many Indian tribes have opposed the expansion of prediction markets into sports betting, with organizations like the Indian Gaming Association (IGA) and California Nations Indian Gaming Association (CNIGA) leading the charge against it, backed largely by larger, more profitable tribes. The tribes currently allying with Kalshi tend to be smaller, independent nations. These partnerships have sparked responses from leaders within the tribes. For instance, Victor Rocha, a member of the Pechanga Band of Indians and Chair of the IGA Conference, referenced the tribal support given to sweepstakes gambling and the financial pitfalls encountered, advising, “Get the money first.”
Matthew Morgan, chairman of the Oklahoma Indian Gaming Association (OIGA), expressed concerns that sports prediction market apps undermine the Indian Gaming Regulatory Act and tribal-state compacts by permitting illegal Class III gaming, jeopardizing crucial revenue streams for tribal programs and services. He pointed out that of the 575 federally recognized tribes, only a few have signed contracts to support Kalshi-backed prediction market applications, and none of them are OIGA member tribes.
In a different area of focus, the federal government has begun investigating staffing reductions at the Commodity Futures Trading Commission (CFTC). Over the past year, the CFTC, which has only one fully occupied commissioner seat with Chairman Michael Selig, has seen its workforce shrink by 21% compared to the previous decade’s average. This drop includes a staggering 22% decrease within a single year, while enforcement actions plummeted nearly 80% in 2025 compared to the previous decade's annual average. The Government Accountability Office is looking into the CFTC's workforce issues following a request from Senator Elizabeth Warren, who questioned the agency's oversight capabilities.
On the front of market competition, FanDuel has shifted its strategy regarding prediction markets. Initially, the company launched a venture with CME Group in August 2025, but due to critical remarks from CME's chairman regarding market dynamics, as well as leadership changes within both FanDuel and its parent company, Flutter, FanDuel opted to switch its sports contracts provider to Crypto.com this year. Now, it has gained independence by owning its own registered futures commission merchant (FCM) license separate from CME Group. The National Futures Association (NFA) lists FanDuel's New Venture III LLC, a FCM, as a registrant as of October 5, reflecting this shift.
Additionally, the Atlanta Braves' Ronald Acuña Jr. has secured a notable landmark in the realm of prediction markets, becoming the first Major League Baseball player to sign a contract with such a platform. Kalshi debuted its commercial featuring Acuña Jr. during Game 4 of the National League Division Series against the Dodgers, despite the Braves’ elimination from contention. The details of the contract have not been disclosed.
Acuña Jr. joins a roster of athletes associated with prediction market companies, including Lionel Messi and Giannis Antetokounmpo with Kalshi, while Polymarket boasts partnerships with stars like LeBron James and Derek Jeter. The connection between MLB and prediction markets is growing; Polymarket is an official partner with both MLB and the New York Yankees, whereas Kalshi has deals with several teams, including the Braves and the Dodgers.
Contrastingly, another high-profile athlete, two-time All-Star Victor Wembanyama of the San Antonio Spurs, publicly criticized his peers for entering into partnerships with prediction market platforms. When asked if he’d consider being a spokesperson, Wembanyama firmly replied, “Absolutely not… I think it’s very sad to see some players promote it… I want to promote things that have a good impact… That’s the strongest thing I can do.”
