Digital Realty Trust shares surged nearly 15% Friday morning, July 24, after the data-center landlord reported record leasing visibility and raised its 2026 outlook. Delayed consolidated market data showed DLR near $206.10 at about 11:50 a.m. ET, up from Thursday's $179.34 close. The move was still intraday, so the final closing gain could differ.

The immediate answer is that investors saw strength in several places at once: new leasing, future contracted rent, renewal pricing and full-year guidance. Digital Realty said second-quarter bookings represented $307 million of annualized GAAP base rent at 100% ownership, or $208.5 million at the company's share. It also signed two hyperscale leases in July representing another $410 million at 100% share, or $205 million at its share.

Those figures suggest demand from cloud, artificial-intelligence and enterprise customers is translating into contracted capacity rather than remaining a broad industry promise. That distinction matters for a real estate investment trust whose growth depends on securing customers before new data-center capacity begins producing rent.

The numbers behind the move

Digital Realty reported roughly $1.9 billion of second-quarter revenue, up 29% from a year earlier. Core funds from operations per share excluding net promote income rose to $2.13 from $1.87. Reported core FFO was $2.65 per share, but that figure included promote income, so the exclusion measure gives a cleaner view of recurring operations. FFO is a non-GAAP metric commonly used for REITs because ordinary depreciation can obscure property-level operating trends.

The signed-but-not-commenced backlog reached a record $1.9 billion of annualized GAAP base rent at 100% share and about $1.43 billion at Digital Realty's share. Cash rental rates on renewal leases increased 25.4%, with the company saying strength in the Asia-Pacific region led the result.

Management raised its 2026 core FFO outlook excluding net promote to $8.15 to $8.20 per share from $8.00 to $8.10. It also lifted expected revenue excluding promote income to $6.85 billion to $6.95 billion, up from the prior $6.65 billion to $6.75 billion range, and increased its adjusted EBITDA range to $3.75 billion to $3.85 billion.

Why investors reacted so strongly

A backlog of signed leases can give investors a clearer path to future revenue, while large renewal increases indicate that scarce capacity and power access may be supporting pricing. The two hyperscale leases signed after quarter-end add another signal that the demand environment remained active into July.

The combination is more important than any single earnings line. A higher outlook says management expects the operating strength to carry beyond one quarter, while the record backlog offers a bridge between current construction spending and future rent. For investors tracking the AI infrastructure buildout, Digital Realty provides exposure through physical facilities, power and connectivity rather than chips or software.

The caveat

Backlog is not current revenue. Digital Realty said the weighted-average lag between second-quarter lease signing and contractual commencement was nine months, and actual start dates can vary. New capacity also requires capital, power availability and timely construction. Customer spending plans, financing costs, competition and foreign-exchange movements can change the outcome.

The 25.4% cash renewal spread may not repeat every quarter, and promote income can make reported core FFO look stronger than the recurring measure. Investors should therefore watch how quickly the backlog begins producing rent, whether renewal pricing remains firm and whether the July hyperscale contracts start on schedule.

What to watch next

The next checkpoints are lease commencements, development deliveries and any further changes to 2026 guidance. Friday's rally shows the market is assigning more value to Digital Realty's contracted growth, but the stock move itself is not proof that every lease will arrive on time or that the shares are fairly valued.
