The White House broke its days-long silence about SpaceX CEO Elon Musk on Friday, as questions swirled about whether Musk had rankled President Donald Trump when he publicly bashed Stargate, the Trump administration's first major tech initiative.

President Donald Trump unveiled this program in collaboration with key figures from the tech industry, including SoftBank CEO Masayoshi Son, OpenAI CEO Sam Altman, and Oracle Chairman Larry Ellison

Trump was joined by SoftBank Group Corp.’s Masayoshi Son, OpenAI’s Sam Altman and Oracle Corp.’s Larry Ellison at the White House to announce the venture, dubbed Stargate, which they said would deploy $100 billion immediately with the goal of eventually spending $500 billion for the construction of data centers and physical campuses.

Mr. Trump had claimed the A.I. announcement as an early trophy, taking credit for the companies’ decision to spend up to $500 billion building data centers.

Masayoshi Son of SoftBank, Sam Altman of OpenAI and Larry Ellison of Oracle joined Trump for the $500 billion announcement.

Elon Musk had sharp words for a private-sector partnership touted this week by the Trump administration to hasten the development of artificial intelligence infrastructure. “They don’t actually have the money,” Musk said of two of the participants in the $500 billion initiative, OpenAI and SoftBank, on his social media site X.
