Ken Griffin Slams Trump Tariffs as “Huge Policy Mistake,” Warns of Long-Term Harm to Families and U.S. LeadershipBillionaire investor Ken Griffin criticized President Donald Trump’s latest round of tariffs, calling them a “huge policy mistake” and likening them to a heavy tax burden on American families.“It’s not right to tell a middle-class or economically struggling family making $50,000 a year that it’s going to cost them 20%, 30%, 40% more for groceries, a toaster, a vacuum cleaner, or a new car,” Griffin said. “Even if the vision of jobs returning to America comes true, that’s a 20-year dream—not 20 weeks, not two years. It’s decades.”Speaking at a University of Miami centennial event, the Citadel founder urged attendees to contact the White House and encourage Trump to reconsider his approach.Griffin joins a growing list of high-profile financial leaders voicing alarm over the potential consequences of Trump’s aggressive tariff policy. Since the announcement last week, global stock markets have plunged, wiping trillions from equity valuations, while foreign governments have issued threats of retaliatory tariffs.Growing Dissent Among Business LeadersHedge fund manager Bill Ackman—despite being a past Trump supporter—warned on social media that the U.S. faces an “economic nuclear winter” if the president doesn’t put the brakes on his trade strategy. JPMorgan Chase CEO Jamie Dimon echoed those concerns, saying the policy “may be disastrous in the long run.”While Griffin has not donated to Trump directly, he is a major Republican donor. According to OpenSecrets, he contributed at least $100 million to pro-GOP political action committees in the last election cycle. His estimated net worth stands at $41.8 billion, per the Bloomberg Billionaires Index.Republican lawmakers have mostly stood by Trump so far, though some dissent is beginning to surface. Senator Ted Cruz of Texas recently warned the tariffs could lead to job losses and broader economic harm.This isn’t Griffin’s first public critique of Trump’s trade policies. In February, he called tariffs a poor negotiation tactic that erode trust with allies and weaken America’s global competitiveness.Now, he says, the fallout from Trump’s tariffs could go beyond economics and threaten the U.S.'s position on the world stage.“We have led the world for 70 to 80 years,” Griffin said. “I’m genuinely worried that we are stepping away from our role as leaders of the free world. That’s the path we’re on.”
