Meta's $145 Billion AI Bet Dropped the Stock-Why a Top Large-Cap Buy Still Makes Sense

Why Meta's Selloff Happened

Meta's latest drop looked less like a collapse in fundamentals than a reaction to funding risk. After management narrowed its 2026 capex range toward the high end and lifted the lower bound of its expense outlook to absorb $2.4 billion legal charges, shares fell about 5% in extended trading. The issue investors are now underwriting is straightforward: can Meta keep spending at this scale and still earn an acceptable return?

The focal point is the $145 billion top end of the 2026 capex plan. Even for a company of Meta's size, that is a massive cash commitment. Bears have a legitimate argument: Reuters Breakingviews noted that Meta lacks the kind of cloud cushion Alphabet, Amazon, or Microsoft has, which makes a rapidly rising infrastructure bet with a slower or less obvious payoff harder for the market to ignore.

Still, this is not a company trying to prove it has a business model. Even after the year of efficiency, Meta still finished 2025 with $200.966 billion in revenue and a 41% operating margin. In other words, the core ad business is still generating enough cash to help fund the AI buildout. That is a very different risk profile from a business trying to finance ambition with debt, dilution, or wishful thinking.

The Street does not seem to view the drop as a broken story. Wall Street still implies 41.90% forecasted upside to the average 12-month target, which suggests the selloff was more about timing and funding anxiety than a consensus rejection of the long-term thesis.

Why the Buy Case Still Holds

The core bullish point is simple: Meta's existing business is still strong enough to support the company's ambitions.

Meta delivered $56.31 billion in Q1 revenue, and full-year 2025 revenue finished at $200.966 billion. The fourth quarter also produced $24.745 billion in operating income. Those figures do not prove AI will be a home run, but they do show that the company has a powerful incumbent business funding its own transformation rather than relying on outside capital to stay relevant.

Why the capex scare may be temporary

Investors are naturally focused on the spending plan, but they should also ask what that spending is supporting. In the latest quarter, revenue still beat estimates even as Meta dealt with user-growth noise tied to internet disruptions in Iran. That suggests the core platform still has considerable shock tolerance.

Just as important, some of the AI spend is already feeding back into the business that pays the bills. Reuters noted Meta's robust ad platform, including automation tools that help advertisers streamline and personalize campaigns. That does not guarantee a clean monetization curve for AI, but it does weaken the bear case that all of this spending is going into a vacuum.

With Meta still trading at a forward P/E of 20 alongside 33% revenue growth, the valuation argument also deserves respect. The market is clearly debating the scale of the investment, not dismissing the company's earning power.

What to watch next

• Cash generation versus capex: Can operating income keep covering more of the spending build without stressing the model?
• AI payoff signals: Are advertiser tools and recommendation systems improving performance in a measurable way?
• Engagement and user trends: Is any weakness localized and temporary, or does it start to pressure the ad machine?

Why the Market Still Flinches

The cleanest bear case is not hard to understand. Meta is accelerating its AI infrastructure build while lacking the kind of cloud cushion that some peer mega-caps enjoy. That makes the funding story harder to ignore, especially when the payoff period looks long.

The bear case, fairly stated

Bears see investors being asked to finance a much heavier operating model before AI has earned its keep. Management now expects $125 billion to $145 billion in 2026 capex, and Reuters reported shares of the company fell about 5% in extended trading after the updated capex and expense guidance. Even a strong business can look stretched when data-center spending is rising this fast and the return window is still uncertain.

That comparison group matters. If Meta could sell more of that infrastructure capacity externally, the economics would be easier to justify. Without that buffer, investors are right to press for clearer evidence that the spending will translate into durable monetization rather than just a larger asset base.

Legal overhang adds to the noise

The market is also reacting to risks outside capex. Earlier this month, Meta faced concerns about billions of dollars in fines and follow-on litigation after rulings tied to harm to young users. That does not overturn the bull case, but it does make the stock harder to underwrite at a moment when management is also asking investors to tolerate a much heavier spending plan.

Still, the broader Street view remains constructive. Wall Street's $789.95 average Wall Street target suggests the stock has been hit on uncertainty, not because analysts think the long-term story has disappeared.

How to think about the setup

This is less a question of whether Meta is a good business-it clearly is-and more a question of whether the market is underpricing the value of an incumbent platform that is funding its own AI upgrade. For investors, the practical approach is to trade the debate, not just the headline.
