Elon Musk’s SpaceX has filed for what could become the largest IPO in history. It could potentially raise a staggering $75 billion. OpenAI is targeting a public offering as soon as September, based on reports. Anthropic is said to be exploring a listing later this year. No surprise that these IPOs have generated a lot of interest. Not only at Wall Street, but also others in the tech industry.
One of the reasons for that is the timing. All three companies sit near the center of the AI boom. All three have already raised enormous amounts of private capital. All three continue to face spending requirements that would have been unimaginable only a few years ago.
OpenAI expects to spend roughly $115 billion over the next four years. Anthropic is reportedly paying SpaceX about $1.25 billion per month for compute. Nvidia recently projected that AI infrastructure spending could eventually approach $4 trillion annually.
The figures offer a glimpse into the economics emerging beneath the AI boom. Building a frontier model is expensive. Building the infrastructure needed to support it at global scale is proving even more costly. As those costs continue to rise, public markets may become the industry’s next major source of funding.
Why are they going public now? The costs of running a modern AI company is one factor.
Every new model requires more computing power and every new customer adds demand for more inference capacity. Similarly, behind every chatbot response sits a growing stack of data centers, GPUs, networking hardware, storage systems, and power infrastructure. Those costs do not just disappear once a model is trained. In fact, in many cases, they continue to grow as adoption increases.
Talent is another factor. Competition for top researchers remains fierce. This is also the primary reason why some of the compensation packages are so high. The right AI leadership talent comes at a premium.
These companies are not simply raising money to grow faster. They are raising money to keep pace with the infrastructure demands of the industry itself. The AI industry’s biggest challenge may no longer be building intelligence. It may be financing it.
Another reason these offerings are attracting attention is that they represent one of the first opportunities for public investors to directly participate in the AI boom. Much of the value creation over the past several years has occurred behind closed doors, benefiting venture capital firms, sovereign wealth funds, and private investors. Public market investors largely watched from the sidelines.

Between them, SpaceX, OpenAI, and Anthropic represent hundreds of billions of dollars in enterprise value. They also sit at different points in the AI stack, spanning infrastructure, foundation models, and applications. Their performance could provide one of the clearest signals yet on how public markets value the economics of AI.
Going public will change how these companies are perceived – and possibly how they are scrutinized. Private companies are often evaluated on their long term vision and strategic positioning. Public companies face a different reality. Investors expect regular disclosure and quarterly results. They also expect a clearer view into how the business is actually performing.
That could prove particularly interesting in AI because many of the industry’s biggest companies have spent years operating behind closed doors. Public filings and earnings reports would provide investors with a far better understanding of revenue composition and operational performance than has previously been available.
While the story is about these three tech giants, the significance extends beyond them. The offerings could help establish valuation benchmarks for the broader AI sector. Think of all the thousands of startups, infrastructure providers, model developers, and enterprise AI vendors currently operating in a market where comparable public companies remain relatively scarce. This sets a bar for them.

This is why you can expect investors, founders, and executives to be watching closely. Strong public market debuts could reinforce confidence across the sector. A weaker reception could prompt more difficult questions about valuation expectations and spending levels. Either way, the upcoming offerings are likely to become an important reference point for how the next generation of AI companies is evaluated.
Earlier this month, AI chipmaker Cerebras Systems completed one of the largest technology IPOs of the year. Investor enthusiasm pushed the stock sharply higher following its debut, highlighting strong demand for AI related offerings and potentially setting the stage for larger offerings from SpaceX, OpenAI, and Anthropic.
