Elon Musk openly questioned whether companies that joined President Donald Trump’s announcement promising hundreds of billions of dollars in artificial intelligence infrastructure could follow through on their promises, exposing an early internal rift within the White House. Trump was joined by SoftBank's Masayoshi Son, OpenAI’s Sam Altman and Oracle's Larry Ellison at the White House to announce the venture, dubbed Stargate, with the goal of eventually spending $500 billion. Altman took to X to dispute Musk’s characterization on Wednesday, calling it wrong and suggesting Musk was upset because the pact could rival the billionaire’s own AI efforts.
