Meta Platforms Inc. (NASDAQ: META) shares took a 4% hit on Monday, and it's not hard to see why. The company is heading into a trial that could cost it up to $1.4 trillion, and a prominent tech investor just called its AI strategy "science fiction." Add in the fact that Communication Services was the weakest sector of the day, and you've got a recipe for a rough start to the week.

The Nasdaq slipped 0.14%, while the S&P 500 fell 0.38%. But Meta's drop was far more pronounced, reflecting company-specific worries.

The Big Trial: What's at Stake?

Here's the situation: 29 state attorneys general have banded together to sue Meta, accusing the company of illegally collecting children's data, misleading consumers about safety, and designing Facebook and Instagram features that encourage addictive behavior in young users.

The case is being heard by U.S. District Judge Yvonne Gonzalez Rogers, with an eight-person advisory jury set to issue a nonbinding verdict. The stakes are enormous. Meta has said potential damages could reach $1.4 trillion, though the states' attorneys have floated a more modest $200 billion figure, according to CNBC.

This isn't Meta's first rodeo with this kind of litigation. The company recently lost a case in New Mexico, where a jury ordered it to pay $375 million, and a judge later added another $567 million to an abatement fund. Meta plans to appeal that one.

The states are also pushing for Meta to delete certain children's data and the algorithms trained on it, and to remove features they describe as addictive. Meta, for its part, calls the claims "unsubstantiated" and the financial demands "vastly disproportionate."

New Mexico Attorney General Raúl Torrez has warned that a massive judgment could hamper Meta's ability to fund future investments. That's a big deal, especially since Meta's AI spending could hit $145 billion this year.

McNamee's Reality Check

As if the legal drama weren't enough, Elevation Partners' Roger McNamee is pouring cold water on Meta's AI ambitions. He called CEO Mark Zuckerberg's open-source AI vision "science fiction that is untethered from reality."

Speaking on CNBC, McNamee suggested Zuckerberg's recent manifesto is more about crafting an image of AI leadership and rehabilitating his reputation than about actual substance. He also challenged the broader AI narrative, urging investors to question whether current large language models can truly deliver the economic transformation markets seem to expect.

"If I owned the stocks today, I'd be sitting there and asking the question, 'Are all my assumptions still sound?'" McNamee said. "Because I think a few of them aren't."

His argument is that large language models essentially predict the most likely response based on historical data. That raises a fundamental question: how many economically valuable tasks actually require an "average result"? It's a fair point, and one that could give AI bulls pause.

Technical Troubles

Meta's stock is also in a precarious technical position. The shares are trading 4.2% below their 20-day simple moving average and 5.1% below the 50-day average. They're even further off the longer-term averages: 6.9% below the 100-day and 9.7% below the 200-day. The MACD is below its signal line, which typically signals weak momentum.

Over the past 12 months, Meta shares have fallen 26.28%. The 52-week range is $520.26 to $796.25, so the stock is closer to the bottom than the top.

Wall Street Still Believes

Despite all this, analysts remain largely optimistic. Meta carries a Buy consensus rating, with an average price target of $767.42. That's a significant upside from current levels, assuming the bulls are right.

UBS maintained a Buy rating but trimmed its price target to $715 on July 30. Baird kept an Outperform rating and cut its target to $750. Goldman Sachs also maintained a Buy and lowered its target to $725. So while the targets are coming down, the overall sentiment is still positive.

Price Action

At the time of publication Monday, Meta Platforms shares were down 4.11% at $565.63, according to market data.

So what's the takeaway? Meta is facing a perfect storm of legal risk, AI skepticism, and technical weakness. But Wall Street sees value, and the company's massive AI investments could pay off in the long run. For now, though, it's a stock that demands careful watching.
