Ok, so this happened today and I watched the live stream so you don't have to. The event is happening May 2026 in Las Vegas, and they have only weightlifting, swimming, and athletics. The only track-specific things they mentioned are that they're building a six-lane track at the venue to host, and that they're offering a $1,000,000 prize for anyone who breaks the 100 metres world record, and $250,000 for any other world record. They're also offering appearance fees like GST and said they would have only around 100 athletes at their first event across all three sports -- this means they would have to be slimming down track a lot, probably only three or four events and not clear if field or distance will be included.
(P.S. as for men's or women's world record, it's unclear to me and the owners seemed to imply but not outright state on Rogan that they would only be having one gender division with the idea that drugs would even out the differences?)
The only athlete displayed was this swimmer Kristian Gkolomeev, who has a best Olympic finish of 5th but he won a silver medal at 2019 swimming worlds. He's 31 now so not washed, and they showed a video of him doped up breaking the 50m freestyle world record by two hundredths of a second. It was a private venue and I'm sure there will be questions about the timing, but I can treat it sort of like the Breaking2 record.
