Meta posted 33% revenue growth in Q1 2026 with advertising firing on all cylinders, yet the stock is down 15% year-to-date as the company raises capex guidance to $125–145B annually and Reality Labs loses $4.03 billion quarterly.

The Good News: Core Business Firing

Meta's advertising business grew 33% in the first quarter of 2026, matching overall revenue growth. Operating income climbed 30%. For buy-and-hold investors, this signals the company's core platform still commands advertiser spending and pricing power, suggesting the competitive moat around Facebook, Instagram, and WhatsApp remains intact.

The Problem: Infrastructure Costs Are Accelerating

Meta raised its 2026 capital expenditure guidance to $125–145 billion annually—a significant figure that reflects management's bet on AI infrastructure, data centers, and custom chips. This investment is necessary to train large language models and power generative AI features, but it's also reducing free cash flow and pressuring near-term profitability.

Reality Labs, Meta's metaverse and VR division, posted a $4.03 billion loss in Q1. While some investors dismiss this relative to overall revenue, it underscores a hard truth: growth-at-any-cost spending can reduce returns even when topline growth looks strong.

What Long-Term Investors Should Consider

The 15% year-to-date decline reflects market skepticism about whether Meta can convert AI infrastructure investments into tangible earnings accretion. For long-term holders, the key question isn't whether the ad business will grow—it will. It's whether the $125–145 billion annual capex will eventually deliver returns greater than the capital cost, or if the company is simply incurring expense to stay competitive in an AI arms race.

Durable competitive advantages matter more than growth rates for buy-and-hold portfolios. Meta's advertising platform remains dominant, but investors need conviction that the company will eventually harvest returns from its AI spending—not perpetually increase it.
