OpenAI Confidentially Files for IPO, Following Anthropic and SpaceX Into Public Markets

Bottom Line Up Front

OpenAI filed confidential S-1 IPO paperwork on June 8, according to Wired AI, joining Anthropic and SpaceX in a potential trillion-dollar public-market race. The company, which raised $122 billion in a private funding round in March, has not committed to a timeline, citing a need to weigh the benefits of going public against the operational flexibility of remaining private. Both OpenAI and its rival Anthropic face the unusual challenge of pursuing public listings despite current unprofitability and revenue far below typical trillion-dollar peers.

OpenAI’s Confidential Filing Strategy

According to Wired AI, OpenAI announced the confidential S-1 filing in a one-paragraph blog post on Monday, noting that the company expected the filing to become public and chose to disclose it preemptively. The company did not specify a timeline or fundraising target, instead framing the IPO decision as contingent on unresolved strategic tradeoffs. “It may be a while because there are things we want to do that are likely easier as a private company,” OpenAI stated, according to Wired AI.

This approach allows OpenAI to monitor Anthropic’s IPO process and adjust course if market conditions shift. By having paperwork ready, the company can move faster if conditions prove favorable or delay if headwinds emerge—a hedging strategy that preserves optionality without committing to a near-term timeline.

Three Companies, Three Valuation Peaks

The IPO wave reflects intense capital competition in frontier AI development. According to Wired AI, Anthropic filed its confidential IPO papers on June 1, one week before OpenAI’s announcement, and its latest private fundraising round valued the company at $965 billion—surpassing OpenAI’s prior valuation of $852 billion. SpaceX, which Wired AI notes also develops AI models alongside its aerospace and satellite-internet operations, publicly filed its IPO papers in May.

All three companies could potentially debut at valuations exceeding $1 trillion. However, Wired AI reports that both OpenAI and Anthropic are unprofitable and generate sales roughly 80–90 percent lower than established trillion-dollar public companies. OpenAI disclosed revenue between $10 billion and $20 billion last year but incurred losses due to substantial spending on cloud infrastructure and scientific staff.

Capital Demand Reshaping Tech Giants’ Strategy

The race for public-market access reflects broader demand for computational capacity. Tech giants including Alphabet, Amazon, Meta, and Microsoft are competing for tens of billions of dollars annually to expand data centers and recruit AI talent, according to Wired AI. Going public would provide OpenAI with additional fundraising capacity while offering employee equity holders and early investors a path to liquidity—potential motivation for staff retention and customer confidence at a moment when OpenAI seeks to reassert leadership in frontier AI.

Why This Matters

OpenAI’s confidential filing signals that the company views public markets as a credible funding option, even without a committed timeline. For customers, this could translate into greater financial transparency and potentially different incentive alignment as a public company. For employees, especially lower-seniority staff hired before the $122 billion funding round, an IPO could unlock meaningful wealth. Conversely, by avoiding a near-term commitment, OpenAI preserves the ability to remain private longer if R&D flexibility—avoiding quarterly earnings pressure—proves more strategically valuable than public-market access. The outcome will likely depend on how Anthropic’s IPO filing progresses and whether market appetite for AI-backed companies at trillion-dollar valuations remains strong.
