Stargate is supposed to spend $500 billion on AI infrastructure, President Trump said. But Elon Musk suggested that the venture has much less cash.

Elon Musk claimed overnight Tuesday that tech giants OpenAI, Oracle and Softbank don’t have enough money to fulfill their high-profile pledge to invest $500 billion in U.S. AI infrastructure.

Shortly after President Donald Trump announced a new massive AI infrastructure investment from the White House, “First Buddy” Elon Musk tried to tear it down. “They don’t actually have the money,” Musk wrote on his social media platform X.
