President Donald Trump’s White House state ballroom project is estimated to cost $600 million, with more than half funded by taxpayers, according to internal contractor documents obtained by The Washington Post — a figure that contradicts Trump’s repeated assertions that private donors would cover all costs.
An internal cost estimate prepared in March by Clark Construction, the project’s contractor, projected the total at $600 million, with approximately $307 million expected from federal sources: $155 million from the White House Military Office, $149 million from the Secret Service, and $3 million from the Executive Residence, according to the Post’s investigation.
Trump has claimed since the project’s announcement in July 2025 that taxpayers would not contribute “10 cents.” On March 31, just weeks before the contractor’s estimate, Trump told reporters in the Oval Office that the ballroom would be “taxpayer-free” and that “we have no taxpayer putting up 10 cents.” Federal records show, however, that the government had already approved more than a dozen payments to Clark Construction totaling tens of millions of dollars in public funds before Trump made those comments.
The cost has escalated dramatically. When Trump first announced the project, he pegged it at $200 million. By October, he said it had risen to $300 million. In December, he acknowledged it could reach $400 million. The March estimate of $600 million represents a tripling of the original figure.
The White House did not answer questions about the internal cost estimates or taxpayer funding. White House spokesman Davis Ingle said in a statement that “President Trump and generous American patriots are funding the ballroom to the tune of approximately $400 million, which will be a secure and appropriate venue for Presidents for generations to come.”
Experts who reviewed the contractor documents told the Post that the project’s structure makes it impossible to separate the entertainment ballroom from the security infrastructure. Stan Soloway, a former Pentagon acquisition official and board chair at the National Academy of Public Administration, said that from a contracting perspective, “you can’t disentangle the entertainment space from all of the other parts that are in here.” He concluded that it is “inevitable that it bleeds over. It’s one structure.”
The funding arrangement has raised ethics concerns among government accountability experts. Richard Briffault, a professor at Columbia Law School who formerly chaired New York City’s Conflicts of Interest Board, warned that when companies with major federal contracts donate to a president’s favored project, it creates the appearance of buying access and influence. “Without any evidence or allegations of quid pro quo, there’s this general sense that you’re kind of buying favorable treatment,” Briffault said.
More than half of the named corporate donors to the ballroom project have received new or expanded government contracts in recent months, according to reporting by Public Citizen and OpenSecrets. Major ballroom donors including Microsoft, Amazon, Google, Palantir, and Nvidia are also among the companies that shaped the Trump administration’s AI Action Plan announced in July 2025, which included executive orders to fast-track federal permitting for data centers and reduce regulatory barriers for tech firms. These same companies stand to benefit substantially from those policies.
Richard Painter, who served as chief ethics lawyer in the White House Counsel’s Office under President George W. Bush, argued that the ballroom represents an unprecedented scale of private funding for a White House project. “There’s never been anything on the scale of this $400 million ballroom,” said Virginia Canter, chief counsel for ethics and anticorruption at the Democracy Defenders Fund. Painter warned that the arrangement poses “a threat to democracy” by turning proximity to the president into a political and financial reward, allowing companies to essentially “sell access to the White House — to his work, his residence and his office — mostly to campaign donors.”
Unlike federal campaign contributions, which must be publicly disclosed, donations to the Trust for the National Mall, the nonprofit managing the ballroom project, are tax-deductible and do not have to be publicly reported. The White House has released a list of donors but has not disclosed the amount of each contribution. This lack of transparency means the public is dependent on what the White House chooses to reveal, even as reporting has identified donors such as Nvidia and Alphabet that were omitted from Trump’s initial list.
