WASHINGTON — A group run by billionaires Bill Ackman and Charles Schwab is launching a six-figure advertising campaign in DC this week to tout President Trump’s American Dream Accounts.

The group, Save Match Grow, is footing the bill for a mobile billboard to drive through Washington and share information about the retirement accounts for tens of millions of workers who don’t currently have access to a 401(k) or another workplace plan.

“Congress can act to secure the financial future of millions by expanding American Dream Accounts,” said Save Match Grow spokeswoman Jessica Anderson. “We need leaders to seize the momentum put in motion by the administration and pass legislation to expand eligibility and boost the value of the federal match.”

“This new program is the type of innovative, transformative policy that rewards work and empowers workers to secure their American Dream,” she added. “The American people are already enthusiastic about this program, and we urge Congress to act expeditiously to cement this bold, commonsense proposal.”

Photos from the group show the billboard car driving near the US Treasury Department on Monday.

On April 30, Trump signed executive action setting up the IRAs for low-income earners who will each receive a yearly federal matching contribution of up to $1,000.

Individuals making less than $35,500 annually, heads of household making $53,250 per year, or couples making $71,000 each year are all eligible, amounting to more than 40 million Americans without traditional retirement accounts.

The Treasury implemented the accounts by leveraging the Federal Saver’s Match program to boost IRA savings.

The American Dream Accounts will particularly help independent contractors, part-time workers, such as those who work gig jobs for Uber, small business employees and self-employed individuals.

TrumpIRA.gov — which launches in January 2027 — provides Americans with the opportunity to enroll in the “high-quality, low-cost” IRA plans offered by private-sector financial institutions, according to the White House.

“I promised to make the same types of retirement accounts enjoyed by federal employees available to all Americans, and that’s what we’re doing. It only seemed fair,” Trump said when signing the order in April.
