Digital Realty (NYSE: DLR) closed up about 11% on Friday to roughly $199, and spiked as much as ~14% intraday to land among the NYSE's top gainers. This is the AI-infrastructure trade paying off in the plumbing.

What actually moved it

Q2 results, out after Thursday's close, were the catalyst. Revenue jumped ~29% year-on-year (and ~18% from Q1) to $1.9 billion. Crucially, the company raised full-year 2026 core-FFO guidance to $8.15–$8.20 a share (excluding promote income), ahead of the ~$8.03 FactSet consensus, and flagged a record ~$1.9 billion leasing backlog. Management pinned it on AI and cloud tenants filling capacity as fast as it comes online.

One honest nuance: the eye-popping headline quarterly FFO was flattered by lumpy development-JV "promote" gains. The cleaner number to judge the business on is that ex-promote $8.15–$8.20 guide — and it still went up.

The market read-through

DLR's backlog is basically hyperscaler AI capex converted into signed, multi-year leases. When Microsoft, Amazon and Alphabet spend on AI compute, a slice lands as booked rent for landlords like Digital Realty and Equinix (EQIX) — so this print is a live tell on data-center demand, not just one REIT's quarter. It also underwrites the picks-and-shovels layer beneath it: power, cooling and grid-interconnect suppliers whose order books track new data-center square footage. Analysts leaned in — BTIG opened coverage at Buy ($215), Guggenheim moved to Buy ($200).

The one risk that flips it

The whole re-rating rides on hyperscaler capex staying hot. The mega-cap cloud names report Q2 over the coming week — if Microsoft, Meta, Alphabet or Amazon signal any capex pullback, the data-center-REIT trade unwinds quickly. With DLR now bumping the ~$215–$220 analyst targets, there's little cushion left if that spending guide cools.
