On April 1, 2025, internet users shared a rumor that investor Warren Buffett of Berkshire Hathaway bought Tesla, billionaire Elon Musk's electric car company, for $1 trillion.

Musk's social media antics were part of an April Fool's prank, but investors weren't laughing. Tesla shares dropped another 5 percent, according to The Washington Post, with business experts openly questioning Musk's ability to lead the multi-billion dollar company.

Tuesday was April Fools’ Day, and while many people love to pull a prank on their loved ones, in recent years, the celebration has escalated to involve brands joining in on the hoaxes — and even some news outlets.
