OpenAI and Anthropic File for IPO in the Same Week, Signaling a Turning Point for AI

The artificial intelligence industry crossed a milestone this week that few expected to arrive so quickly. OpenAI submitted a confidential draft registration statement to the Securities and Exchange Commission on June 8, exactly one week after Anthropic made the same move. Goldman Sachs and Morgan Stanley are leading OpenAI's filing process. Both companies are targeting a potential fall listing.

The timing is not coincidental. Investors who have spent years backing AI at extraordinary valuations are now seeking liquidity. Anthropic's annualized revenue reached approximately $47 billion in May 2026, up from roughly $10 billion the prior year, a fivefold growth rate that makes it one of the fastest-scaling software businesses ever measured. OpenAI, which generates revenue through ChatGPT subscriptions and its API platform, has not disclosed equivalent figures in its filing but is widely expected to report comparable growth.

The week also saw SpaceX begin trading on Nasdaq under the ticker SPCX, targeting a $75 billion raise at a valuation exceeding $1.75 trillion, the largest initial public offering in recorded history. SpaceX reported $18.7 billion in consolidated 2025 revenue, with Starlink accounting for $11.4 billion of that total. xAI, which SpaceX acquired in February 2026, consumed approximately $14 billion in cash against $3.2 billion in revenue, a dynamic that will face scrutiny from public market investors accustomed to tighter unit economics.

The three filings together mark a structural shift in how artificial intelligence companies relate to public capital markets. Until this month, the largest AI laboratories had remained private, accessible only to institutional investors and sovereign wealth funds willing to accept illiquid positions and multi-year horizons. Public listings change that equation entirely, creating price discovery, quarterly accountability, and the kind of analyst coverage that shapes how the broader technology industry is understood.

For enterprise buyers, the IPO wave carries its own implications. Public companies face disclosure requirements that private ones do not. Quarterly earnings calls will force OpenAI and Anthropic to discuss customer concentration, contract renewal rates, and compute costs in ways that competitive intelligence teams across every major industry will parse closely.

The question that public markets will ultimately answer is one that private valuations have so far deferred: whether the revenue growth currently being generated by AI laboratories reflects durable enterprise adoption or an early wave of experimentation that has not yet been tested by budget cycles, integration complexity, and organizational change management. Both answers are possible. The filings will begin to tell us which one is true.
