Key Takeaways
Voyager Digital investors filed an appeal on June 23 asking the U.S. Court of Appeals for the Eleventh Circuit to revive a class-action lawsuit against Mark Cuban and the Dallas Mavericks.
A Florida federal judge dismissed the case in December 2025 on jurisdictional grounds, not on the merits of the securities and consumer-protection claims.
The suit traces to Cuban's October 2021 endorsement of Voyager, which collapsed into bankruptcy in 2022, and tests how far celebrity crypto promoters can be held accountable.
Voyager Digital investors filed an appeal on June 23 asking the U.S. Court of Appeals for the Eleventh Circuit to revive their class-action lawsuit against Mark Cuban and the Dallas Mavericks, according to Crypto Briefing and Law360. A Florida federal judge had dismissed the case on December 30, 2025.
The dismissal turned on jurisdiction, not on whether Cuban did anything wrong. The judge ruled that Cuban and the Mavericks did not have enough Florida-specific contacts for a Florida court to hear the claims. That is a venue question, not an exoneration, which is why the investors are appealing rather than walking away.
The underlying complaint, Robertson v. Cuban, was filed in August 2022, about a month after Voyager sought Chapter 11 bankruptcy protection. The investors say Cuban endorsed Voyager at a Mavericks press conference on October 27, 2021, telling the crowd he had personally invested, and that the team's sponsorship deal with the platform, reportedly worth more than $25 million, helped push retail customers onto a service whose risks were not clearly disclosed. When Voyager failed in the 2022 downturn, those customers lost money.
Cuban is the rare holdout. The other celebrity promoters named in Voyager-related cases, including Rob Gronkowski and Victor Oladipo, settled for a combined $2.4 million in 2024, according to The Crypto Times, and exited. Cuban and the Mavericks fought through jurisdictional discovery and a full dismissal instead.
The thread here is accountability, and who carries it when a trust-based pitch goes wrong. A public figure says he is in, retail follows, the platform breaks, and four years later the courts are still sorting out who owes what. The same question runs through a securities and racketeering class action against the company behind Pump.fun and through the federal oversight now being extended over crypto firms like Coinbase. The most notable part of this is the timeline, since a single 2021 press conference is still generating federal litigation in 2026. Worth watching.
