The 2024 U.S. presidential election has become the most expensive in history, with a total expenditure of $15.9 billion. Kamala Harris's campaign raised over $1 billion but ended with $20 million in debt, despite out-fundraising and outspending Donald Trump's campaign, which raised $388 million. Harris's campaign reportedly spent $5 million more per day than Trump's, with significant funds allocated to high-profile concerts and celebrity endorsements. As of mid-October, Harris's campaign had $118 million in the bank. Despite the substantial financial backing from media, Hollywood, Big Business, and Big Tech, Harris lost the election to Trump. Overall, Harris's campaign spent $1.02 billion, contributing to the most expensive U.S. election in history.
