Summary: Anthropic filed a confidential Form S-1 with the SEC on 2026-06-01 at a $965B valuation with annualized revenue above $47B. OpenAI filed its confidential S-1 on 2026-06-08 at a $852B last-round valuation. SpaceX priced its IPO at $135 per share on 2026-06-11, targeting 555.6 million shares for a $75B raise at a $1.77T valuation; Nasdaq listing is set for 2026-06-12 under ticker SPCX. SpaceX bypassed the standard price-range roadshow and went straight to a fixed price. The S-1 explicitly positions SpaceX as an AI compute infrastructure company.
Why it matters: All three companies moving toward public markets in the same quarter increases enterprise AI procurement scrutiny and consolidation pressure. SpaceX's $75B raise is the largest IPO by capital raised on record.
