Ruling adds to a wave of major crypto lawsuit dismissals in the US in 2025.
Adding to the growing list of high-profile crypto lawsuits settled in the US in 2025, a Federal Judge has dismissed a prolonged class-action suit against Mark Cuban and the Dallas Mavericks. This marks a significant win for the defenders as the judge ruled in their favour, adding that the plaintiffs had insufficient claims against them.
Mark Cuban Crypto Lawsuit Dismissed
In a remarkable development, a Federal judge has dismissed a crypto lawsuit against Mark Cuban and the Dallas Mavericks. The judge reportedly ruled that the court lacked personal jurisdiction over the defendants. The defendants’ legal team stated,
“The complaint asserted claims under various state securities laws and consumer fraud statutes. On December 30, the U.S. District Court for the Southern District of Florida Judge Roy K. Altman dismissed the matter in its entirety.”
It is noteworthy that the dismissal of the Mark Cuban lawsuit comes on the heels of the closure of multiple crypto lawsuits in 2025. Under the Donald Trump administration and the restructured regulatory watchdog, numerous cases were dismissed. For instance, the much-awaited Ripple vs SEC lawsuit finally ended in August this year. Other major platforms like Binance and Coinbase have also secured major wins in their legal battles.
Unveiling Plaintiff Claims
Filed in 2022, the lawsuit alleged that Mark Cuban and the team defrauded investors by promoting Voyager Digital, a now bankrupt crypto lender. They were accused of misleading investors into opening accounts on the platform, offering them rewards in Bitcoin.
As per reports, the lawsuit claimed that the Mavericks offered $100 in BTC to users downloading the Voyager app and executing a trade. However, the federal judge, Roy K. Altman, dismissed these claims, asserting that Cuban’s promotional activities couldn’t be considered as a purposeful target of Florida residents.
Mark Cuban’s lawyers had argued that he wasn’t responsible for the Voyager Digital collapse. They pointed out that Cuban had warned investors to be cautious with their investments in the platform. The legal team had also requested the court to exempt him from promotional allegations. They cited that Mark Cuban had informed users that the involved assets weren’t securities.
A ‘Clear Win’ for Mark Cuban, Says Legal Team
In response to the judge’s ruling in favour of Mark Cuban and the Dallas Mavericks, Steve Best, lead counsel, shared his enthusiasm. Best stated, “We couldn’t be more pleased with the absolute right result.” He added,
“I suspect that the plaintiffs will consider filing in another jurisdiction. … I look forward to defending Mark and the Mavericks in any jurisdiction in this country. “Mark doesn’t settle when he believes he is on the right side of the law.”
Interestingly, the connection between crypto and sports goes beyond partnerships and promotions. Ironically, they are more connected through lawsuits. This Dallas Mavericks case is just one example of the many lawsuits that target celebrities and athletes who endorsed crypto and blockchain projects, which later became bankrupt. In addition, prediction market platform Kalshi faced a fresh lawsuit recently, accused of illegal sports gambling. The suit argues that Kalshi claims to provide “legal sports betting” despite lacking a gaming license in the US.
