META Stock Just Had Its Worst Day in Nearly a Year. Here's What Happened.

Meta Platforms (META) stock fell approximately 8% on Thursday, March 26, in what amounted to the company's worst single-day decline in months. The sell-off was driven by a convergence of legal setbacks, broader market weakness tied to the escalating U.S.-Iran conflict, internal restructuring moves, and persistent investor concerns about the company's massive capital expenditure commitments.

The most significant catalyst was the fallout from back-to-back jury verdicts finding Meta liable for harm to young users on its platforms. A Los Angeles jury ruled late Wednesday that Meta and Alphabet's (GOOGL) (GOOG) YouTube were negligent in contributing to the mental health issues of a 20-year-old woman through addictive platform features, awarding $6 million in damages with Meta assigned 70% of the responsibility. Separately, a New Mexico jury earlier in the week found Meta liable for violating state consumer protection laws related to child safety and ordered the company to pay $375 million in penalties, the maximum allowed under state law.
