Meta’s AI Spend Grows to $72B, But Investors Still Want Ads to Pay the Bills

Meta’s latest earnings report showed strong ad performance but an even stronger appetite for AI spending.

The company lifted its full-year capital-expenditure guidance to as much as $72 billion, joining Alphabet and Microsoft in announcing heavier investment in computing power.

The move sent Meta stock down 11%, losing about $215 billion in one day in its steepest drop in three years, as investors questioned how long it would take to see returns.

CEO Mark Zuckerberg defended the AI spend during the Q3 2025 earnings call, saying he believes "it's the right strategy to aggressively front-load building capacity."

"That way, if superintelligence arrives sooner, we will be ideally positioned for a generational paradigm shift and many large opportunities.

If it takes longer, then we'll use the extra compute to accelerate our core business, which continues to be able to profitably use much more compute than we’ve been able to throw at it," he added.

While Wall Street balked at the cost, the tech giant reported Q3 2025 adjusted earnings of $7.25 per share on revenue of $51.24 billion, exceeding expectations.

Advertising remains the foundation: 98% of revenue still comes from ads across Facebook, Instagram, and WhatsApp, which is nearly the same as the 97% ad revenue for Q1 2024.

Ads Still Power Meta’s Growth

Despite the AI spotlight, Meta’s ad business remains its most reliable asset.

Ad sales jumped 26% from a year earlier, outpacing Amazon, Alphabet, and Microsoft for the quarter.

Experts say the company’s use of AI to improve ad targeting and performance is already lifting results, even if bigger AI-related projects may take years to monetize.

“Meta’s ad success gives it room to invest in building real AI capability," Aleksey Gureiev, technical lead at multidisciplinary tech agency Shakuro, told DesignRush.

"The scale of this effort shows they’re thinking long-term gains. It sets the foundation for new products, smarter systems, and the kind of innovation that takes years to fully show its value.”

The contrast between Meta’s high Q3 revenue and investor unease shows how the company is funding tomorrow’s AI ambitions with today’s ad dollars.

Facebook’s Brand Steps Back Into the Spotlight

Earnings week also saw the debut of Facebook’s first brand campaign in four years.

Titled “A Little Connection Goes a Long Way,” the new film reconnects Facebook with younger users while returning to its roots.

Real people, relationships, and moments of connection are highlighted in this new push from global creative agency Droga5.

The one-minute ad highlights Marketplace and Groups, which are used by 1 in 4 young-adult Facebook users in the U.S. and Canada.

As part of the campaign, another spot, "Home for the Holidays," will air on college football broadcasts and NBC’s "Wicked" special, with placements across Peacock, Disney+, Netflix, and Prime Video.

It will also run in cinemas and on social platforms, including TikTok and Snapchat.

The brand campaign arrives at a key moment for Meta, reintroducing Facebook as a space built for community while the company pours billions into AI.

Investing in Two Timelines

Meta is now straddling two worlds.

Its future depends on AI research and supercomputing, but its present still relies on ad revenue and user engagement.

The company’s $27 billion Hyperion data center in Louisiana, financed through private credit, reflects how capital markets are being used to fund AI infrastructure at scale.

At the same time, campaigns like Facebook’s holiday film remind users and advertisers what built Meta’s success in the first place. Connection remains its most durable currency.

Meta’s latest quarter offers several takeaways for brands and marketers watching its shift:

• Innovation must stay visible. Even as Meta invests heavily in infrastructure, it’s using creative storytelling to keep audiences emotionally engaged.
• Advertising still defines relevance. AI may improve efficiency, but human connection keeps the brand relatable.
• Consistency builds confidence. Balancing long-term vision with short-term reliability keeps users and investors aligned.

Meta’s strong Q3 earnings prove the ad business still carries the company.

The open question is whether AI will eventually sustain itself or continue to depend on its ad platform for profit.

Our Take: Can AI and Ads Coexist for Meta?

Will AI investments finally yield profits in a few years to complement ad revenue, or will its ad business always be the one footing the bill?

I think the answer really depends on how well Meta manages both timelines at present and in the future.

The company is asking investors to fund a future that takes years to materialize while relying on ads for steady growth.

This is a hard balance to maintain, but also what defines this era of Big Tech: innovation powered by the cash flow of yesterday’s success.

For now, I believe Meta’s AI story is still theoretical.

The ad business, however, remains proof that human connection, not infrastructure, is what keeps the lights on.
