About this market
Anthropic's accelerated path to a potential late-September or October 2026 listing, with banker discussions targeting valuations above $1.5–2 trillion on surging revenue run-rates near $65 billion annualized, underpins its narrow lead in implied probability over SpaceX. The AI lab's confidential S-1 filing in June and post-Labor Day prospectus plans position it to eclipse SpaceX's completed June IPO at $1.77 trillion—the prior record—while xAI's integration into SpaceX removes it as a standalone contender. Trader consensus reflects Anthropic's faster revenue scaling and IPO timing edge versus SpaceX's established scale, with outcomes hinging on final pricing multiples, market sentiment toward AI valuations, and any shifts in listing windows amid broader equity conditions.
