Key Takeaways A lawsuit over Mark Cuban’s Voyager promotion is heading to a federal appeals court. It was dismissed in December 2025 on jurisdiction, not on the merits. The allegations agains
The crucial thing to understand is that no court has ruled on whether Cuban did anything wrong. In December 2025, Judge Roy K. Altman dismissed the case, but not on its substance. He dismissed it because the plaintiffs failed to establish that a Florida court had jurisdiction over a Texas-based billionaire and a Texas-based NBA franchise. That is a procedural outcome, not a verdict. The court never decided whether the Voyager promotion was misleading, whether Cuban knew the platform was risky, or whether investors were harmed by his endorsement.
On June 23, 2026, the plaintiffs filed a notice of appeal to the Eleventh Circuit, challenging that dismissal directly. The appeal also contests a May 2026 order in which the court declined to reopen the case or transfer it to Texas, where the jurisdictional problem would not exist.
These remain allegations, untested in court, and worth stating as such. Filed in 2022, the suit claims Cuban and the Mavericks marketed Voyager Digital to fans as a “risk-free” investment platform and promoted it through incentives such as $100 in Bitcoin for making a deposit. The plaintiffs argue this amounted to promoting unregistered securities, and that investors who acted on the promotion lost money when Voyager failed.
Voyager filed for Chapter 11 bankruptcy in July 2022 after Three Arrows Capital defaulted on a roughly $650 million loan, triggering a run that wiped out customer funds. The legal question the plaintiffs want answered is whether the celebrity promotion that drew some of those customers in carried legal responsibility. Cuban and the Mavericks have contested the claims, and won dismissal on the jurisdictional grounds described above.
Cuban was not the only public figure named. The other celebrity defendants, Rob Gronkowski, Victor Oladipo, and Landon Cassill, settled for a combined $2.4 million in 2024 and exited the case. A settlement is not an admission of liability, and none was established, but their departure leaves the spotlight entirely on Cuban and the Mavericks, who chose to fight rather than settle. That choice produced the dismissal, and now the appeal.
One piece of context has shifted during the years of litigation: Cuban sold his majority stake in the Mavericks to Miriam Adelson, so the franchise’s ownership today is different from when the promotion took place.

If it reverses Altman’s dismissal, the case returns to district court and would finally be litigated on its merits, testing the questions that have never been answered: did the promotion mislead investors, and was Voyager an unregistered security? If the appeals court upholds the dismissal, the plaintiffs could potentially refile in Texas, where jurisdiction would not be a barrier, or the case could end entirely.
The plaintiffs’ team adds weight to the effort. Alongside Adam Moskowitz of the Moskowitz Law Firm, the plaintiffs are represented by David Boies of Boies Schiller Flexner, one of the most prominent litigators in the country, known for high-profile cases against major institutions. His involvement signals the appeal is being resourced seriously rather than treated as a long shot.
The case sits at the center of a question the crypto industry has wrestled with since the 2022 downturn: how much legal responsibility public figures carry for the platforms they promote. Several celebrity-endorsement crypto cases have been settled or dismissed, but few have reached a full ruling on the underlying liability. If this appeal succeeds and the case is finally heard on its merits, it could become one of the clearer tests of where promotion ends and legal accountability begins. For now, nothing is decided. The dismissal stands, the allegations remain unproven, and the Eleventh Circuit will determine only whether the fight continues at all.
