The High Stakes of Public Ownership: OpenAI, Anthropic, and SpaceX Face Wall Street’s Scrutiny
The hard part is about to begin – As the AI sector continues to evolve, three of its most prominent players—OpenAI, Anthropic, and SpaceX—are preparing to enter the public market. This shift marks a critical juncture for these companies, as they transition from private ventures to entities accountable to shareholders and financial analysts. OpenAI, the creator of the widely popular ChatGPT, recently announced its intention to go public, following Anthropic’s confidential IPO filing earlier in the week. SpaceX, which houses Elon Musk’s AI-focused subsidiary xAI, is set to launch its initial public offering on Friday. These developments are expected to offer investors a deeper insight into the current state of the AI industry, with potential stock sales surpassing hundreds of billions of dollars.
Market Volatility and Investor Appetite for Growth
Wall Street’s appetite for AI-driven innovation has never been higher, yet the expectations for these companies are equally ambitious. Investors now demand not just steady progress but explosive growth every three months, a stark contrast to the more flexible timelines of private funding. This pressure is evident in the recent performance of semiconductor stocks, which have experienced significant declines. For instance, Broadcom, a major collaborator with OpenAI and Anthropic, reported remarkable financial results in its second quarter, including a 48% revenue increase. However, the stock price fell over 13% in the following week, signaling that even impressive earnings may not satisfy market demands.
“People want more,” said Stacy Rasgon, a semiconductor analyst at Bernstein, in a discussion with CNN. “They always want more.”
The broader market has also shown signs of strain. The Nasdaq fell for three consecutive days, while the S&P 500 faced its worst day since October. An exchange-traded fund focused on memory chips dropped 15% last week, underscoring the high stakes of AI-related investments. These fluctuations highlight the volatility that comes with public ownership, where companies must constantly prove their worth to maintain market confidence.
The Burden of Public Market Expectations
Public market scrutiny brings a new level of accountability for AI firms. While private investors may support a company’s vision for years without immediate returns, public shareholders expect rapid results. Nigel Green, CEO of deVere Group, noted that “expectations that seem manageable in private markets can become relentless under the glare of public ownership.” For AI startups like OpenAI and Anthropic, this means their valuations—already reaching the trillion-dollar mark—are now subject to intense evaluation. Any delay in product launches or shortfalls in revenue projections could lead to sharp declines in stock value.
OpenAI and Anthropic have already demonstrated strong growth, but their public offerings will serve as a litmus test for the industry’s future potential. OpenAI disclosed that it raised $122 billion in March, pushing its valuation to $852 billion. The company also revealed that it generates $2 billion in monthly revenue, a significant jump from its previous quarterly earnings of $1 billion. ChatGPT’s rapid user growth, which reached one billion in just three months, further solidifies its position as a market leader. This achievement outpaced the timeframes of established apps like Google Maps and YouTube, which took five to eight years to hit similar milestones.
Anthropic’s trajectory has been equally impressive. The company’s valuation surged from $380 billion in February to $965 billion in May, surpassing OpenAI. In May, it reported a run-rate revenue of $47 billion, a metric that estimates annual revenue based on current trends. The fintech firm Ramp noted that Anthropic’s customer base grew faster than OpenAI’s in May, indicating a shift in market preference. These metrics suggest that both companies are not only thriving but also reshaping the competitive landscape of AI development.
From Private Visionaries to Public Accountability
The path to public ownership is a transformative step for any company. OpenAI and Anthropic have chosen to disclose their financial data to date, signaling confidence in their strategies. However, this transparency comes with risks. Analysts will likely probe the CEOs—Sam Altman for OpenAI and Dario Amodei for Anthropic—on future plans, product timelines, and the ability to convert cutting-edge models into profitable offerings. For example, OpenAI’s recent decision to shut down its video app Sora may draw closer scrutiny, as investors seek to understand the rationale behind such pivots.
Even the most successful AI firms are not immune to public market pressures. Take Nvidia, the world’s most valuable publicly traded company, which lost $600 billion in market value in January 2025 after DeepSeek, a Chinese competitor, entered the scene. This loss highlights the fragility of public AI stocks when faced with new threats or shifts in investor sentiment. As OpenAI and Anthropic navigate their IPOs, they will need to address similar concerns: Can their models maintain momentum in a rapidly changing market? Do they have the financial resilience to sustain growth?
The public offering is not just about capital raising; it’s about proving the scalability of their business models. OpenAI and Anthropic have both signaled their readiness to face this challenge. Yet, the road ahead remains uncertain. With Broadcom and Nvidia struggling to meet investor demands, the AI sector faces a delicate balance between innovation and profitability. The IPOs of these companies could either validate their potential or expose vulnerabilities in their growth strategies.
Implications for the AI Industry and Beyond
The public market debut of OpenAI and Anthropic may also influence the broader AI ecosystem. As investors allocate billions to these companies, it could drive further innovation in areas like natural language processing and generative models. However, it also raises questions about the sustainability of such rapid growth. Will these companies be able to maintain their momentum, or will the pressure to deliver consistent returns lead to strategic adjustments?
Analysts will be watching closely for any signs of instability. Earnings calls will become a battleground for these firms, where every detail—whether it’s a delay in model releases or a pivot in business focus—could sway investor confidence. The success of these IPOs will not only determine their futures but also set a precedent for other AI startups vying to enter the public market. As the industry moves toward greater transparency, the challenge for these companies will be to demonstrate that their innovations are not just groundbreaking but also profitable in the long term.
