Key facts
- Fight: Sept 18, 2026 at REK’s Van Ness Avenue venue (opened July 2026); LaPenna faced robots including an adult-size EngineAI T800 and one REK calls ‘The Predator’
- CSAC letter (late September; reported as Sept 23 by USA Herald and Sept 30 by other outlets): stop ‘holding, promoting, or advertising any boxing or mixed martial arts contest match or exhibition, involving any human’ in California without commission approval (SFist)
- REK argues the law covers only fights between persons; whether the robots were teleoperated is not stated in the sources read
- The fight video had ~8.2M YouTube views by Oct 7 (SFist)
What happened
The commission treats the bouts as unsanctioned combat sports. Liv has framed the letter as publicity.
Why it matters
Consumer humanoids are now strong enough to be used in combat entertainment, and the first regulator to respond did so under old boxing law. The question of whether a robot “contestant” counts is open.
