Bill Ackman’s net worth: The hedge fund billionaire’s wealth in 2025

Bill Ackman is one of several high-profile billionaires who in April made headlines for their statements regarding President Trump’s tariff-fueled trade war.

After initially expressing concern over the President’s aggressive tariff implementation, Ackman applauded Trump’s subsequent pause on tariffs with America’s trading partners. When Trump then upped tariffs on China while pausing reciprocal tariffs on other U.S. trading partners on April 9th, 2025 — causing the U.S. stock market to briefly skyrocket after previous lows — Ackman tweeted, “This was brilliantly executed by @realDonaldTrump. Textbook, Art of the Deal.”

Also on the 9th, Ackman reposted an ominous, all-caps tweet — ostensibly about tariffs — from the official White House account that reads like a line from The Empire in Star Wars:

DO NOT RETALIATE AND YOU WILL BE REWARDED— The White House (@WhiteHouse) April 9, 2025

Days later, however, another tweet from Ackman seemed to indicate that he would prefer a pause on tariffs against China to allow time for small businesses to make supply chain adjustments. As of this article’s last update, imported products of Chinese origin face tariffs of between 125% and 245%.
