OpenAI has officially announced that it confidentially filed a Form S-1 registration statement with the US Securities and Exchange Commission (SEC) for a proposed initial public offering. This move has been long awaited in the AI industry. This lands just over a week after its primary competitor, Anthropic, made an identical confidential move. It also comes just days before Elon Musk’s SpaceX is set to begin its historic public roadshow.
A confidential filing allows OpenAI to submit its internal financial health data to federal regulators for comprehensive review without making sensitive parameters visible to the open public. This includes executive compensation, business risks, and exact revenue figures. However, the company bluntly admitted it chose to post the news on its corporate blog simply because leadership expected the paperwork to leak to the press anyway.
The multi-billion-dollar cash burn
A public market debut undoubtedly marks a massive milestone for any tech company. Still, the timing highlights the staggering financial strain underneath the hood of frontier AI development. Building, training, and running massive AI models remain among the most capital-intensive corporate endeavors in history.
According to reports, OpenAI recently missed its internal targets for user growth and revenue. Chief Financial Officer Sarah Friar has reportedly raised serious concerns regarding whether the company can successfully cover its aggressive infrastructure spending limits. The firm secured a historic $122 billion in a recent Silicon Valley funding round. However, internal projections indicate OpenAI expects to burn roughly $85 billion in 2028 alone. This is just to keep up with pure computing research.
In other words, public market investors are being asked to buy into an $852 billion business that openly projects it will not generate more cash than it spends for at least another four years.
A historic three-way battle for capital
The race to cross the public market finish line first carries incredibly high stakes. Financial experts suggest that whoever debuts first will likely absorb the lion’s share of institutional capital, which is becoming increasingly scarce as initial market hype cools down.
The competitive landscape has grown fiercely complex. Anthropic recently closed a massive funding round pushing its retail secondary market valuation to a whopping $965 billion. This way, Claude’s parent company officially eclipsed OpenAI’s latest valuation bench.
Meanwhile, SpaceX is preparing to launch its own massive public debut targeting a $1.75 trillion valuation. SpaceX recently absorbed Elon Musk’s xAI and established a massive data center partnership with Anthropic. So, OpenAI’s upcoming performance on Wall Street will be directly measured against Musk’s expanding technological empire.
Entering the third phase
In a separate post, OpenAI CEO Sam Altman framed the transition as the beginning of “the third phase of OpenAI.” According to Altman, the first phase focused on foundational research, while the second centered on refining the product through consumer feedback from ChatGPT‘s massive base of 900 million weekly users. This upcoming phase, he argues, is entirely about internal discipline and scalability.
To prepare for public scrutiny, OpenAI has been quietly trimming fringe operations. The firm entirely shuttered secondary projects like the short-form video application Sora to funnel every available resource into high-yield enterprise tools and its Codex programming ecosystem. Whether public investors will happily fund a multi-billion-dollar computational burn rate while the company scales these revenue models remains the trillion-dollar question hanging over Wall Street.
