SpaceX IPO becomes litmus test for AI giants' Wall Street debut

Three of the world's most ambitious technology companies are preparing to test whether Wall Street will pay for the future. SpaceX, OpenAI, and Anthropic are all moving toward public markets, and together they aim to raise more than $240 billion—a sum that exceeds every dollar raised through initial public offerings in the United States during the previous two years combined. But before any of them rings the opening bell, the market will render its first verdict on whether investors are willing to fund the kind of infrastructure-scale ambitions that have defined artificial intelligence's explosive growth.

SpaceX arrives first, and its reception will shape everything that follows. The company is targeting roughly $75 billion in its offering, which would value it somewhere between $1.75 and $2 trillion. That valuation reflects something genuinely difficult to categorize. SpaceX is not simply a rocket company, though it has become essential to American space launches and government contracts. It is also Starlink, the satellite internet service that has evolved into the company's true financial engine, generating recurring revenue and serving millions of users. And now it is also xAI, Elon Musk's artificial intelligence venture, which reframes the entire enterprise as something more than a space operator. The market will have to decide whether these pieces belong together or whether they should be valued separately. The structure of the offering itself signals that Musk is not interested in letting public markets dictate terms. Only a limited number of shares will be released, which typically drives prices upward in early trading. A meaningful portion has been reserved for retail investors, adding an emotional component to demand. And the control structure ensures that current shareholders will retain their grip on the company. The implicit message is clear: this is not a traditional business case. It is a bet on future execution—on whether SpaceX can complete Starship, transform Starlink into an even more profitable global infrastructure, and somehow make all of it work together.

OpenAI follows in SpaceX's wake, and the company carries a more complicated burden. It is the most visible artificial intelligence company in the world, the one that brought the technology to mainstream consciousness, and the one that has shaped the entire conversation about what AI can do and where it is headed. Its planned offering targets roughly $100 billion, reflecting both its ambitions and its capital needs. But that visibility cuts both ways. In recent months, doubts have begun to surface that were not part of the conversation before. Some internal forecasts for user growth and revenue have not materialized. The rate of expansion, while still substantial in absolute terms, is showing signs of slowing relative to more aggressive competitors in the enterprise market. The cost of maintaining and scaling its models continues to climb at a pace that is difficult to sustain even with Microsoft's backing. The business structure itself raises questions. OpenAI depends heavily on consumer subscriptions, with millions of paying users, but the monetization does not always scale at the same speed as usage. Its position in the corporate segment has weakened against rivals who committed more directly to that market. Within the company itself, there is disagreement about timing. Sam Altman is pushing to move forward and capture the current market window. But some voices in leadership believe the company is not yet ready for the scrutiny of public markets and argue for waiting until 2027. That difference matters. It is the difference between raising money to fuel growth and waiting to prove that growth can become a predictable, sustainable business.

Anthropic, the company founded by the Amodei brothers, occupies the middle ground. It is targeting an offering that could exceed $60 billion, but it arrives with a different narrative. The company has grown with less media fanfare but with consistent execution in the enterprise segment. Much of its revenue comes from contracts with large corporations, which gives it a more stable foundation and less exposure to the volatility of consumer demand. That positioning has translated into rapid revenue growth and increasing presence in development tools and corporate environments. Its partnerships with major cloud providers allow it to scale without depending on a single infrastructure, and it has positioned itself as a serious alternative to OpenAI in areas like programming. When Anthropic goes public, it will serve as a contrast to both SpaceX and OpenAI. While SpaceX tests the market's appetite for gigantic, complex operations and OpenAI measures the durability of the most visible AI narrative, Anthropic will reveal whether investors are willing to reward models built around revenue and customers rather than future promises.

Behind this trio lies a longer queue of companies waiting their turn. Databricks and Cerebras Systems occupy a less visible but equally critical role. They do not sell consumer-facing assistants or viral applications. They sell the infrastructure that makes everything else possible. Databricks has become one of the major platforms where companies store, process, and prepare data for training AI models—essentially the kitchen where the fuel for these systems is prepared. Cerebras designs enormous chips optimized for training artificial intelligence models far faster than traditional GPUs. For these companies, going public is not an opportunity but a necessity. Venture capital financed the early phase, but it falls short when scaling to industrial levels. Building data centers, developing new chips, and maintaining infrastructure capable of training increasingly complex models requires continuous investment that no longer fits within private funding rounds. The public market becomes the logical next source.

Yet capital is not arriving as easily as it once did. After years of excess, investors are beginning to demand something beyond promises. They want revenue, margins, and some visibility into how a business actually works. That is where many of these companies still have to prove that their growth does not depend solely on enthusiasm for artificial intelligence. There is another group playing a different game entirely. Canva, Stripe, and Klarna are not at the center of artificial intelligence, but they have used it to feed enthusiasm around their products. Canva has integrated generative tools into its design suite. Stripe uses AI to improve payments, fraud detection, and automation. Klarna has incorporated it into customer service and recommendations. None of them depends on AI to exist, but all have incorporated it to avoid being left out of the dominant narrative. That gives them a more comfortable position. They have businesses that already work, clear revenue streams, and models that are easier to understand. AI adds to the story but does not carry it.

The picture is now clear. On one side are companies that need billions of dollars to build infrastructure that is still being deployed. On the other are businesses that already generate cash and use AI as an additional lever. Both will arrive at the same market at the same time. What gets decided there is more than the success of a few IPOs. It is what kind of story the market is willing to buy right now—the promise or the profit and loss statement. For years, private capital allowed many technology companies to grow protected from uncomfortable questions about margins, profitability, or financial sustainability. Wall Street works differently. It demands answers every quarter. That transforms this new wave of offerings into something more than a race for money. It is the moment when the artificial intelligence industry will have to demonstrate how much of its narrative can survive when prices are set every day by the market.
