OpenAI Accelerates the AI IPO Race With a Confidential Filing, Following Its Rivals

The battle for dominance in artificial intelligence is shifting decisively to Wall Street. OpenAI has confidentially filed for a U.S. IPO, just days after rival Anthropic made the same move. All signs point to 2026 becoming the year when the biggest AI players cash in their multibillion-dollar valuations on the public market.

According to WIRED, OpenAI submitted a confidential filing for an Initial Public Offering on Monday. The maker of ChatGPT is following not only Anthropic but also SpaceX, which kicked off its own listing process earlier this year. All three rank among the world’s most valuable private tech companies.

The timing underscores how fast AI is maturing. After years of venture capital fueling the boom, a new phase is opening up—one where public investors can finally get in.

One word: scale. Building cutting-edge AI now demands tens of billions of dollars for infrastructure, chips, data centers, and research.

OpenAI, alongside partners like Microsoft, is pouring money into massive AI infrastructure projects. Anthropic is rapidly advancing its Claude models and has raised billions from Amazon and Google, among others. Yet the capital needs keep climbing.

A public listing unlocks near-limitless financing. It also gives early backers, employees, and shareholders a chance to partially cash out.

A confidential filing doesn’t mean an immediate debut. In the U.S., companies can spend months refining their prospectus behind closed doors before releasing financial details.

The trajectory mirrors the late-’90s and early-2000s internet wave, when Google, Amazon, and later Facebook went public after securing dominant positions in explosive markets.

The difference now: valuations could be even larger. Analysts have long speculated that both OpenAI and Anthropic could eventually push toward, or even past, the trillion-dollar mark.

That would make these listings among the biggest tech IPOs in history.

Notably, many investors are now backing multiple AI players at once. WIRED previously reported that VCs liken OpenAI vs. Anthropic to Coke vs. Pepsi: both benefit from the same surging market.

That’s why major funds often hold stakes in several AI firms simultaneously. The expectation is clear: demand for generative AI will keep rising, no matter who ends up on top.

For public markets, that’s a shift. Until now, the AI boom showed up mostly through chipmakers like NVIDIA and cloud giants like Microsoft. Now, the model developers themselves are edging closer to the trading floor.

The IPO race marks a turning point. Competition has centered on tech performance and talent. Going public adds a new mandate: deliver growth, profitability, and transparency to shareholders.

That could reshape strategy. OpenAI and Anthropic won’t just battle on model quality but also on financial execution and market share.

At the same time, political pressure is rising. The U.S., Europe, and Asia are moving toward stricter rules for advanced AI. Publicly listed AI companies will face even more scrutiny from regulators and the public.

With OpenAI’s confidential filing, Anthropic’s earlier move, and SpaceX’s listing plans, a clear pattern is emerging: the biggest private tech firms are gearing up for a new chapter.

For AI, that means more capital, more visibility, and fiercer competition. For investors, it could finally open a direct route into the companies driving today’s AI revolution.

The question is no longer if AI firms will go public, but which one will claim the defining tech IPO of the AI era.
