Mark Cuban has had a rough few years in crypto court. Now, just when he thought he’d cleared one of the bigger legal hurdles, investors are back for another round.
Voyager Digital investors filed an appeal on June 23, 2026, asking the US Court of Appeals for the Eleventh Circuit to revive their class-action lawsuit against Cuban and the Dallas Mavericks. The case had been dismissed by a Florida federal judge on December 30, 2025, on the grounds that the court lacked personal jurisdiction over the defendants.
What the lawsuit is actually about
The original complaint, Robertson et al. v. Cuban et al., was filed in August 2022, roughly one month after Voyager Digital sought Chapter 11 bankruptcy protection in July of that year.
The core allegation: Cuban publicly endorsed Voyager at a Mavericks press conference on October 27, 2021, telling the crowd he had personally invested in the platform. The Mavericks also had a sponsorship deal with Voyager reportedly valued at over $25 million.
