# California athletic commission orders San Francisco startup REK to stop human-vs-humanoid-robot cage fights

The California State Athletic Commission sent a cease-and-desist letter to Robot Entertainment Kombat (REK), a San Francisco startup that on Sept 18, 2026 staged what it billed as the first human-vs-robot fight: influencer Frankie LaPenna against humanoids including an EngineAI T800. The letter bars unsanctioned contests involving humans and warns that unlicensed promotion is a misdemeanor. CEO Cix Liv posted it on X ("We made it boys"). Coverage spread widely on Oct 7–8 (SFist, Tom's Hardware, The Verge, NYT video).

## 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.
