NEW YORK -- America’s first billionaire president may soon be profiting from a new line of business tied to his office: charging access for a first peek at certain posts on his Truth Social platform.

Donald Trump's struggling media company plans to sell Wall Street traders the chance to see posts from “highest-ranking” accounts — including possibly his own — milliseconds before others.

That could mean big money for them, and Trump.

Trump's posts are often important enough to rattle financial markets, sending prices soaring and plunging within seconds. Until this moment, presidential policy announcements were considered sort of public property that should be free and available to all at the same time.

The president has the most followers on Truth Social — 12.9 million — so presumably will be included in the mix of high-ranking accounts.

Truth Social’s public parent, Trump Media & Technology, did not respond to emailed questions, including whether Trump’s posts will be excluded from the offering, but the planned service is attracting plenty of attention — and not just from traders.

“It’s odious, selling access to highest bidders on Wall Street," said Dylan Hedler-Gaudette, an expert on federal ethic rules at watchdog Project on Government Oversight. “Everything he says has market implications."

Called Truth PSI, the service announced in a short press release Thursday would allow Wall Street trading firms and institutions to see certain posts earlier than other users so they could profit off subsequent moves in stocks, bonds and interest rates.

The Trump Media release did not give any sense of the size of the new business but quotes CEO Kevin McGurn as saying he expects it to become a “meaningful" source of revenue as part of a strategy to "monetize proprietary assets.” The company added that it expects to launch the service next month.

The customers that Truth Social is targeting are high frequency traders who jump ahead of others in reacting to news to buy and sell bonds and other financial instruments. And a few thousands of a second often spells the difference between profits and losses.

When Trump announced his sweeping tariffs on April 2 last year, it was major political and financial news —- and many found out first on Truth Social.

“It's Liberation Day in America," Trump posted hours before a formal Rose Garden announcement, sending stocks plunging nearly 5% over the next few hours. Safe haven investments like gold and Treasury bonds soared.

A few days later, Trump reversed course by suspending the tariffs for 90 days with an announcement again on Truth Social, writing, "THIS IS A GREAT TIME TO BUY!!!”

Stocks soared 9.5% that day, adding $4 trillion to investor wealth as measured by the S&P 500 index.

“It’s yet more brazen corruption,” said Kathleen Clark of Washington University School of Law and an expert in government ethics rules. “Trump can line his pockets by selling access.”

Trump has announced major decisions and musings about other topics, including staff changes, immigration crackdowns, and matters of war and peace in Ukraine and Iran.
