California's athletic commission tells robot league REK to license any fight with a human in it
California's athletic commission ordered robot-fight league REK to stop staging bouts involving any human without a license after a September 18 cage fight. For anyone building robot entertainment, a person in the ring now means getting commission approval before the first ticket is advertised.
The Product Desk
What happened
- The letter cites California business code sections that make an unlicensed contest a misdemeanor for anyone required to hold a commission license.
- REK chief executive Cix Liv posted the letter publicly with the caption "We made it boys."
- REK still lists three robot-versus-robot weapon fights in San Francisco for October 9, with tickets selling at $69.
Compiled by The Product DeskSomething wrong?How this is made
Why it matters
- constraint A California event with a human contestant needs commission approval before it is advertised, so the regulator now decides when the ticket page can go live.
- exposure The licensing clause covers participation as well as promotion, so an influencer who books a bout against a robot falls within its terms alongside the company.
- contradiction Dexerto framed the order as shutting REK down, but the letter's text covers only contests involving a human, so on its face it does not reach the robot-only weapon card.
- decision Builders of fighting robots now choose between a licensed human-versus-machine event and a robot-only card that avoids the commission but drops the bout that drew the attention.
Frankie LaPenna stepped into a cage on September 18 to face a humanoid robot with a Terminator head. According to The Verge, another person was steering the robot through what The New York Times described as a "remote virtual-reality system" [3]. Dexerto put the machine at six feet tall [4]. The Verge said the body appears to be an EngineAI robot with a different head fitted [16]. So two people took part in the fight, one in the cage and one at the controls [14].
REK pitches something else. Its Instagram calls the company "Real Steel IRL," after the 2011 film set in a future where robots have replaced humans in professional boxing [5]. Its website says it is "the humanoid robot fighting league" [12]. The pitch is machines hitting machines. The September 18 event was a person in a cage fight, and in California a boxing or martial arts contest involving a person needs the State Athletic Commission's approval and license [2].
The commission's letter has two clauses, and both hinge on the same phrase [1]. The first orders REK to stop "holding, promoting or advertising any boxing or mixed martial arts contest match, or exhibition, involving any human" in the state without prior approval [2]. The second covers "the promotion of, or participation in" such a contest without a license under Business and Professions Code section 18640 [2]. Advertising is on the list, so the ticket page is covered. Participation is also on the list, so the wording reaches the fighter as well as the promoter [2]. The letter cites sections 18870 and 18878, under which an unlicensed contest is a misdemeanor for anyone required to hold a license [13].
Dexerto reported that REK was ordered to cease operations [15]. The letter is narrower than that. REK's next card is three robot-versus-robot weapon fights in San Francisco on October 9, with Wolverine-style claws and blades, and Dexerto reported tickets still on sale at $69 [10]. The Verge also describes the next match as two armed robots fighting each other [11]. As written, the letter's clauses reach contests involving a human, and that card has no human contestant [17].
Cix Liv, REK's chief executive, posted the letter himself. "We made it boys," Liv said [7]. The Verge dates his post on X to September 30 [8]. Dexerto dates it to October 1 and quotes the caption calling it a cease and desist for an "UNSANCTIONED HUMAN VERSUS HUMANOID ROBOT CAGE FIGHT" [9].
For a team building physical robot entertainment, the letter answers one question. In California, a human contestant puts the event under the athletic commission, whatever the opponent is made of [2]. The sources do not say what a license costs or whether REK has applied.
The test for any format is whether a person can get hit, and where. One axis is whether a human is a contestant. The other is whether the event is in California, the only state this letter covers [2]. With a human contestant in California, you need commission approval before the event is advertised [2]. A robot-only card in California falls outside the letter's wording [17]. Bouts outside California, human or robot-only, are outside this letter, and REK has run matches in the US, Japan and Canada [6].
If the draw is a person against a machine, I would plan it as a licensed combat event from the first day. The cost is an approval and licensing step before any ticket goes on sale [2]. You also lose the "unsanctioned" label Liv was celebrating [9]. The other route is a robot-only card. It stays outside the letter's text but gives up the human-versus-machine bout that brought REK to the commission's attention [1].
What to watch
- Whether the California State Athletic Commission takes any action against REK's October 9 robot-only weapon card in San Francisco.
- Whether REK applies for a commission license or moves its human-versus-robot bouts outside California.
- Whether the commission treats a remote human pilot as a human "involved" in a contest.

The letter states that Business and Professions Code sections 18870 and 18878 make it a misdemeanor for a person or promoter required to be licensed by the State Athletic Commission to hold, aid or abet, or attempt to hold, any contest, match or exhibition without first obtaining a license or permit.

The September 18 bout involved at least two humans: LaPenna in the cage and the remote pilot controlling the robot.

Dexerto reported that the company has been ordered to cease operations by California regulators.

The robot appears to be one from EngineAI with a Terminator-like head swapped on top.

As described, the October 9 card has no human contestant, so it falls outside the letter's text, whose clauses cover only contests involving a human.
