In May 2025, Misha Cirkunov filed an antitrust lawsuit against Zuffa which included fighters that signed a an arbitration agreement two updated fighter contracts.
From our post in May 2025:
The Complaint appears to be a mirror image of the Le and Johnson cases. However, this one is updated to encompass fighters who had signed the arbitration agreement and waiver amendment to fighter contracts.
The Kajan Johnson lawsuit encompasses those fighters that had not signed arbitration or waiver agreements.
The Cirkunov lawsuit sweeps up the rest of fighters who were precluded from the Johnson case.
Essentially, Cirkunov adopts the filings of Le and Johnson but includes a section about those that signed Arbitration Agreements and Class-Action Waivers.
This fall we’ve seen discovery disputes between the parties dealing with the scope of discovery. Essentially, the plaintiffs want an extensive review of information including phones used by Dana White during the relevant time period. On the other hand, defendants believe the lawsuit should be limited to what they believe is at issue, whether or not there was an arbitration agreement in the contract. In February 2026, White is scheduled to testify on the matter of his phone and we shall see what becomes of it and if there is information that has been not disclosed.
