Kalshi, a rapidly growing prediction market platform, has found its business increasingly threatened following a breakdown in talks with Native American tribal gaming leaders, leading to multiple lawsuits that could significantly impact its operations. The New York-based company allows users to place wagers on a variety of events, including the Oscars, weather phenomena, and notably sports contests, which reportedly contribute to as much as 70% of its estimated $4 billion revenue in the year ending July 2025.
The core of the dispute lies in whether Kalshi’s offerings, which the company labels as financial instruments called "event contracts" and "swaps," constitute unauthorized sports gambling under federal Indian gaming laws. Several tribes have filed lawsuits in California, New Mexico, and Wisconsin aiming to halt Kalshi’s market activities, arguing that the company’s event wagers function effectively as unregulated gambling that diverts revenue from tribal casinos.
Earlier in 2025, Kalshi’s CEO Tarek Mansour engaged in discussions with key tribal officials, including Victor Rocha of the Pechanga Band of Indians and conference chairman of the Indian Gaming Association (IGA), in an attempt to reach common ground. Mansour proposed Rocha join Kalshi as an advisor, a move that Rocha publicly rejected, perceiving it as a superficial effort to co-opt tribal influence and divide indigenous communities. Rocha characterized Mansour’s approach as insincere and likened it to a tactic to create a false perception of tribal support for Kalshi.
Subsequent video conferences involving Mansour, other Kalshi executives, and tribal leaders such as Jason Giles, executive director of the IGA, revealed deep mistrust. Giles expressed concern that Kalshi’s intent was to expand wagering through partnerships on tribal casino floors, which the tribes viewed as a threat undermining their regulatory authority and economic interests. Both Rocha and Giles pointed to a history of hardship and the significance of sovereignty and trust, emphasizing that Kalshi’s overtures failed to acknowledge these sensitivities in a meaningful way.
The deterioration in relations was further exacerbated by public exchanges, with Rocha using social media to criticize Mansour and call for a concerted tribal response to Kalshi, stating, "we all should agree to keep curb stomping Kalshi" with "no mercy." Rocha also declined to feature Mansour on a webinar aimed at educating tribal leaders and regulators about Kalshi’s business, signaling a hardening stance and a clear expectation of legal confrontation.
Kalshi representatives maintain that the company sought constructive dialogue and potential partnerships, viewing their product as distinct from traditional gambling. They argue that Native American casinos, which generated $46 billion in revenue last year, wield considerable market power and are using lawsuits to stifle competition. From Kalshi’s perspective, tribal gaming enterprises are well-established “juggernauts” rather than vulnerable entities.
On the other hand, tribal leaders contend that Kalshi’s market siphons off potential revenue critical for tribal jobs, infrastructure, and community programs. Mark Macarro, president of the National Congress of American Indians and a Pechanga Band chief, testified before the Senate Indian Affairs Committee that diverted dollars from prediction markets have a tangible negative impact on tribal economic development.
The dispute is poised to continue through the courts, with the Ninth Circuit recently ruling against Kalshi in one tribal suit, raising prospects of a Supreme Court hearing that may determine the future regulatory landscape for prediction markets and tribal gaming interests alike.
