The Magnificent Seven stocks have been hurt by several developments in 2026. For Meta Platforms, the company is cutting jobs and spending aggressively on AI growth. The company has also been hit with several recent court rulings that could lead to more legal challenges.

Meta shareholders are paying the price for the uncertainties with shares down 18%. Among the biggest losers is Meta co-founder Mark Zuckerberg.

Zuckerberg started the year as the sixth-richest person in the world, with a net worth of $233 billion.

Recent hits to Meta’s stock price have sent Zuckerberg’s wealth down significantly. While Zuckerberg is still the sixth richest person in the world, he is now worth $187 billion, down $46.3 billion year-to-date.

On Friday alone, Zuckerberg’s wealth fell by $7.7 billion, with Meta’s stock price falling on the heels of legal rulings.

Zuckerberg is one of the biggest losers in terms of net wealth in 2026, based on calculations for the Bloomberg Billionaires Index.

The $46.3 billion year-to-date decline comes after Zuckerberg added $26 billion to his net worth in 2025.

Zuckerberg owns around 13% of Meta’s shares, so any volatility in the stock can cause wild swings in his net worth.

Meta was recently found negligent in a landmark social media trial where a jury found Meta and Alphabet’s YouTube caused harm with addictive apps. The $3 million ruling was far from a large amount for Meta, given its size, but there is concern that the ruling could see more lawsuits targeting social media companies.

The ruling also came after a recent $375 million penalty awarded against Meta in a New Mexico lawsuit alleging that Meta misled users over child safety.

Meta will likely appeal both cases, but both cases set a precedent that social media companies can be found liable for the way their apps are addictive and for not taking extra precautions for the safety of younger users on the platform.

Meta stock could see further declines if more court cases come forward, which would, in turn, send Zuckerberg’s net worth even lower.
