For the past two years, Nvidia Corp (NASDAQ:NVDA) has emerged as Wall Street’s preferred way to bet on artificial intelligence. It benefited from an arms race among AI developers scrambling to secure computing power.

The next challenge to its dominance in investor portfolios may not come from a rival chip company. It may come from some of Nvidia’s biggest customers.

SpaceX, OpenAI and Anthropic are among the most closely watched private companies in the world. While SpaceX has filed its S-1 with the SEC and aims for a $2 trillion IPO and fast-track entry into NASDAQ indices, OpenAI and Anthropic haven’t disclosed imminent timelines.

Investors and analysts have long speculated that public listings could eventually rank among the largest technology offerings in history. Collectively, the three companies command valuations that already stretch into the hundreds of billions of dollars.

Something went wrong.
