Zuckerberg's Wealth Drops $18 Billion as Meta Shares Slide on AI Spending Worries

The Staggering 11-Day Slide That Erased $18 Billion From Zuckerberg's Fortune

Meta Platforms shares suffered their worst single-day loss of the year on 30 July, plunging 9% and capping an 11-day rout that erased over a fifth of the company’s market value. The stock's 21.7% slide since mid-July has directly hit CEO Mark Zuckerberg, whose net worth fell by $17.8 billion in the same period to $185.3 billion, according to the Forbes Real-Time Billionaires list. Zuckerberg remains the world’s sixth-richest person, ahead of Nvidia’s Jensen Huang ($168.7 billion) but behind Michael Dell ($228.8 billion).

The trigger was Meta’s second-quarter earnings report, which revealed adjusted earnings per share of $6.18—far below the $7.18 analysts had expected—even as revenue topped forecasts at $60.8 billion. Crucially, the company lifted its full-year spending forecast to $137.5 billion and declined to offer any guidance for 2027, stoking fears that an aggressive artificial intelligence expansion is eroding profitability.

Wall Street’s response was swift and negative. Scotiabank cut its target price on Meta from $700 to $600, while Wedbush Securities reduced its target from $671 to $595. Several other major firms—including Evercore ISI, Wolfe Research, Goldman Sachs, and Cantor Fitzgerald—also sliced their targets by $90 to $110. The common thread: deep uncertainty over when, or if, Meta’s soaring AI investments will produce meaningful revenue.

Why Investors and Analysts Turned Sour on Meta's AI Gambit

A Bet on AI That the Street Isn't Yet Ready to Buy

Meta’s leadership has bet heavily that artificial intelligence will define the next decade of growth, but the second-quarter numbers offered no evidence that the payoff is near. Earnings missed estimates precisely because the company poured resources into AI infrastructure and research that have yet to boost the top line in a visible way. The decision to raise annual spending to $137.5 billion—and to stay silent on the path beyond—sends a message that costs will remain elevated, pressuring free cash flow and the share buybacks that investors have relied on. Until Meta can point to AI-generated revenue, the spending will be viewed as a drag on returns.

Analyst Downgrades Flood In as Patience Wears Thin

The wave of target-price cuts from Scotiabank, Wedbush, and others reflects a fundamental shift in the Street’s posture. Scotiabank’s Nat Schindler explicitly warned investors to stop focusing on the size of Meta’s AI opportunity and instead demand evidence of monetization and discipline on spending. Wedbush echoed that sentiment, urging investors to gauge whether the billions being spent on AI will ever translate into sustainable financial gains. The cuts—some as deep as $110—signal that even previously bullish analysts now see a lower fair value for the stock, at least until management provides a clearer roadmap.

The Year’s Troubling Pattern

This sell-off is not happening in a vacuum. Meta shares are already down roughly 18% this year, battered by unfavorable court rulings and persistent doubts about the company’s ability to navigate an evolving tech landscape. A brief rally in early July—when the stock climbed more than 14% in a week after the launch of the AI image-generation tool Muse Image—quickly fizzled. That product drew sharp criticism from Hollywood unions, talent agencies, and cybersecurity firms over privacy risks, highlighting the reputational pitfalls that come with pushing AI products before the public is ready. The episode shows that even product wins can be undone by trust deficits, adding another layer of risk to an already uncertain investment case.

What Meta's Sell-Off Signifies for Investors, Rivals and the AI Race

• For Meta shareholders: The next several quarters will hinge on any sign that AI-driven features are lifting ad revenue or user engagement. Watch the Q3 earnings call for management commentary on AI monetization and any hint of a spending ceiling. Without that, the stock is likely to remain under pressure.
• For Meta management: The message from the market is clear—prioritize preserving strong free cash flow over unbridled AI expansion. Providing even conservative 2027 spending guidance could ease some uncertainty, while demonstrating revenue traction from current AI products would directly address the trust deficit.
• For competitors in social media and AI: Meta’s stumble creates a window. Companies with leaner AI strategies or clearer paths to monetization may attract investor capital that is now leaving Meta. Rivals in digital advertising could also seize market share if Meta’s core services are distracted.
• For Mark Zuckerberg personally: With the vast majority of his wealth tied to Meta stock, the $17.8 billion drop is a stark reminder of how closely his fortune is linked to the company’s AI narrative. Additional policy missteps—like the privacy backlash against Muse Image—could further erode his net worth and his ability to steer Meta’s long-term direction without investor pushback.
