Equinix Ramps Up Spending Plans Amid Faster-Than-Expected AI Shift

Equinix is dramatically increasing both its revenue outlook and its planned development spending, signaling confidence from the world’s largest data center firm that it is uniquely positioned to capitalize on the AI infrastructure boom. 

Equinix reported strong second-quarter earnings Wednesday, with revenue up 16% year-over-year. Booking grew by more than 30%, with the vast majority of the largest deals driven by artificial intelligence workloads. 

But it was Equinix’s unexpectedly bullish forward-looking projections that raised investors' eyebrows.

The company sharply raised its growth expectations, both for revenue and the expansion of its data center portfolio, with annual development spending now potentially more than double the level forecast just a year ago.   

Equinix raised its revenue growth projections for 2026 to 12%, representing a $100M increase over prior guidance. And Equinix now anticipates annual revenue growth of 10% to 13% between 2027 and 2029 — far above the 7% to 10% range it projected just a year ago.

Equinix CEO Adaire Fox-Martin said on the REIT's Wednesday earnings call this revision was “the largest single guidance raise in the history of our company.”

The optimistic revenue projections are tied to a similarly dramatic increase in planned development spending. For 2026, Equinix’s projected annual capex leapt from a prior outlook of $3.8B to as much as $6B. Annual capex for 2027 to 2029 is now predicted at $5B to $7B, up from the earlier estimate of $3B to $4B. 

On its call with analysts Wednesday, Equinix’s leadership said that while the firm’s new, more aggressive expansion plan partially stems from stronger-than-expected demand over the past quarter, it’s also a reaction to an AI infrastructure ecosystem that is evolving to match the firm’s business model and portfolio. 

“As the market has evolved, the nature of the demand has given us greater conviction in our plan,” Fox-Martin said. “The demand signals are clear. Our strategy is working, and the investments we are making today are designed to drive sustainable, long-term growth, well above our prior expectations.”

Since the beginning of the AI data center boom, even as the industry’s growth shifted toward massive campuses often far from established markets, Equinix has leaned into its core business model centered on smaller, more connectivity-focused facilities near population centers. 

Equinix executives have long argued that the AI boom would ultimately play to the company’s strengths.

At the heart of this thesis is the expectation that, as corporations and consumers put AI to use, demand will increasingly shift from training AI models to inference, the computing to run those models in real-world applications. Unlike training, inference workloads often need to be located close to end users and in connectivity-focused facilities where data can be transferred easily between multiple cloud providers and networks — a niche Equinix believes it is uniquely positioned to dominate. 

Now, Equinix executives say this shift is happening even faster than they expected.

Fox-Martin said the company’s more aggressive growth projections reflect greater confidence that AI demand is increasingly flowing toward its interconnection-focused portfolio. 

“We have definitely seen acceleration in the AI infrastructure cycle … and that plays directly to the strength of Equinix,” Fox-Martin said. “We are uniquely positioned, I believe, to enable our customers and our partners to execute their AI strategies, particularly as they shift to inferencing.”

This conviction is shaping the geography of Equinix’s development strategy. Roughly 80% of the firm’s planned development spending will be concentrated in Equinix’s largest existing markets — places where its connectivity infrastructure is most robust, where demand far exceeds supply and where new development faces significant barriers. 

Equinix’s leadership touted the company’s unique ability to deliver new capacity in the most power-constrained markets as a critical competitive advantage. The company has 3 gigawatts of developable land under control, with around 770 megawatts being developed. 

“Most deployment of the capital … will be in our top 25 markets, that we understand well, where we have a competitive advantage, where demand is higher than supply, and we have already today a strong ecosystem with the utility providers, with global contractors and with the community,” Chief Financial Officer Olivier Leonetti told analysts Wednesday.

Wall Street seems sold on Equinix’s vision, with the REIT’s share price up around 4% by midday Thursday. 

Still, Equinix hasn't been immune to the industrywide concerns about the massive scale of AI infrastructure spending that have rattled tech giants like Google. Multiple analysts, both on Equinix’s Wednesday earnings call and in subsequent notes to investors, have expressed anxiety about the risk inherent in the company's aggressive spending plan if demand does not materialize to the degree the firm envisions. 

“[T]he scale of this infrastructure buildout raises concerns that data center operators may be left with excess capacity and poor returns on capital,” Morningstar Equity research analyst Martin Szumski wrote in a note to investors Thursday.
