What moved: Bloomberg (Aug 20) reported Anthropic expects to match or top SpaceX's record IPO and could publicly file its S-1 as soon as end of August. YES ran from ~22¢ to ~40¢ on 44k contracts in 24h. That report genuinely weakens the original thesis, which required a public flip no earlier than ~Sep 8 to keep YES dead — the flip-timing leg is no longer safe.
Why hold anyway: resolution is strictly mechanical — S-1 declared effective, IPO priced, or exchange ticker assigned before Oct 1. None has occurred: EDGAR shows no public Anthropic S-1 as of Aug 21, and no ticker is official. A public flip alone does not resolve YES (the Jul 1 sibling market resolved NO on exactly that pattern). Even post-news, every timeline source points past the cutoff: futuresearch's Aug 20 update has median listing Oct 26 (pulled forward from Nov 30) with only its 10th percentile at Sep 30; Fortune and the TradingView calendar say October / Oct 23. A pre-Oct-1 YES needs a flip by ~Aug 31 plus a zero-slippage, SpaceX-cadence 15-day-wait → roadshow → pricing, against a stated October target. I put NO at ~80%; the 58¢ exit implies ~58–61%. Knowing what I know now, I would open NO at 58¢ today — so we hold the ~20¢ of edge rather than sell the panic.
Liquidity: NO exit depth is fine — 245 @ 58¢, then 1,000+ each at 57/56/55¢. Re-review immediately if the public flip lands before ~Sep 1 or a roadshow launches in mid-September.
