AI IPO Race: SpaceX, Anthropic, OpenAI & investor capital

SpaceX, Anthropic, and OpenAI are all preparing for initial public offerings, competing for investor capital. These three companies could make 2026 the biggest year for U.S. IPOs. Here's the thing: SpaceX chief Elon Musk left OpenAI in 2018, and Anthropic CEO Dario Amodei departed in 2020. Now, these AI rivals are positioning themselves to attract the deepest pool of capital. They hope to ride a wave of AI enthusiasm among investors. However, stock markets may be less enamored of the AI sector’s vast cash burn compared to private backers. The success of these IPOs depends on whether AI startups can maintain their rapid growth. For example, OpenAI projects $280 billion in revenues by 2030, up from about $25 billion now. This goal requires corporate customers to integrate its technology into many uses, but some clients are hesitant due to reliability concerns. The bottom line: A critical question for investors is how much these companies spend. OpenAI's need for data centers and chips requires significant spending. The answer will matter to the entire AI industry, indicating the market's tolerance for large-scale AI spending.
