American Eagle's recent advertising campaign featuring actress Sydney Sweeney has sparked controversy and significant market activity. The campaign, which includes the tagline "Sydney Sweeney has great jeans," faced backlash amid accusations that it alluded to white supremacy. Sydney Sweeney, who has been registered as a Republican in Florida since 2024, has not publicly responded to the controversy. U.S. President Donald Trump publicly praised the ad after learning of Sweeney's political affiliation, calling it "fantastic" and "the hottest ad out there," and encouraged consumers to support it. Trump's endorsement contributed to a sharp increase in American Eagle's stock price, which surged as much as 24% on August 4, marking the company's largest single-day gain in 25 years and pushing the shares into meme stock territory. Despite the backlash, American Eagle has doubled down on the campaign. Trump also contrasted his support for the ad with criticism of "woke" culture, notably criticizing singer Taylor Swift. The episode highlights the intersection of politics, advertising, and market reactions, with American Eagle benefiting from the attention generated by the controversy and presidential endorsement.
