Washington (December 11, 2025) - Senator Edward J. Markey (D-Mass.), member of the Commerce, Science, and Transportation Committee, today wrote to Jared Isaacman, President Trump’s nominee to be Administrator of the National Aeronautics and Space Administration (NASA), and Executive Chairman of Shift4, urging Isaacman to release the amounts he paid to SpaceX for spaceflights. At a recent Commerce Committee hearing, Isaacman committed to ask SpaceX to release him from any non-disclosure agreement that would prevent him from publicly sharing these amounts. Isaacman’s financial disclosures suggest he paid over $50 million for spaceflights, but the exact number is unknown.

In the letter, Senator Markey writes, “I requested that you publicly disclose the amount of money you paid SpaceX for two space flights and you agreed to request that SpaceX release you from any non-disclosure agreement (NDA) that would prevent you from disclosing that figure. Given this commitment, I request that you immediately ask to be released from any NDA and, upon SpaceX lifting any confidentiality restrictions, promptly disclose to my office the amount you paid SpaceX for these flights. The American people deserve a NASA Administrator who will prioritize America’s leading role in exploring and understanding the universe, not one who will prioritize enriching SpaceX’s CEO, Elon Musk.”

When Jared Isaacman first appeared in front of the Commerce Committee in April, Senator Markey questioned Isaacman on whether Elon Musk was in the room when Donald Trump offered him the nomination to be NASA Administrator. Isaacman refused to answer. At his second nomination hearing in December, Senator Markey pressed Isaacman to reveal how much Isaacman paid for spaceflights with SpaceX. Once again, Isaacman refused to answer.
