Overview
- A privately organized competition held in Las Vegas permitted elite athletes to use substances banned by major sport authorities and offered large cash prizes intended to reward world‑record performances.
- Organizers said treatments used at the event are legal drugs and were administered under medical supervision, framing the format as transparent human performance evolution.
- Organizers reported at least one million‑dollar record bonus awarded after a swimmer posted a time that organizers said beat the 50m freestyle world mark.
- World Anti‑Doping Agency rules and national federations reject the format, while medical experts warned of short‑term and long‑term risks such as cardiovascular, liver and kidney damage from anabolic steroids and growth hormones.
- Backers from tech‑libertarian and private capital circles have turned the experiment into a commercial spectacle that could pressure regulators, influence youth behavior and force new debates about where sport, medicine and entertainment meet.
