FuelCell Energy touts modular on-site power for data centers

Digital Realty made ServiceFabric MCP available on September 15, a software layer that lets AI agents design, monitor and troubleshoot network connections across more than 800 data centers, including third-party sites. The launch follows second quarter results reported on July 23, when Core FFO per share, excluding net promote, rose to $2.13 from $1.87 a year earlier, while the headline figure of $2.65 included a $188 million net promote. Renewal leases in the quarter were signed at rates 25.4% higher on a cash basis, and signed leases waiting to start added up to a $1.9 billion backlog of annualized base rent at 100% share. Management lifted its 2026 Core FFO per share outlook, excluding net promote, to $8.15 to $8.20, even as the company carried about $18.6 billion of debt at June 30, 2026 and set its 2026 development spending outlook, net of partner contributions, at $4.25 billion to $4.75 billion. Digital Realty calls MCP an emerging standard still being validated, and the announcement puts no dollar figure on what it could add to revenue.

The top five US hyperscalers are projecting a combined capital expenditure of $660 billion to $725 billion for 2026, nearly double their 2025 outlays, as the AI build-out shifts from software to physical infrastructure. Microsoft is guiding for roughly $175 billion in adjusted capital expenditure for both FY2026 and FY2027, with two-thirds of quarterly spend going to short-lived assets like CPUs and GPUs and the rest to long-lived data center infrastructure, and it added 1 gigawatt of capacity in Q3 FY2026, doubling its global footprint in two years. Amazon AWS has raised its 2026 capex guidance to approximately $220 billion, with CEO Andy Jassy saying AI capacity is expected to remain constrained through 2027 and contracted demand extending into 2028. Meta saw profit drop 14% in Q2 2026 despite a 28% revenue increase as its build-out, including a 1 gigawatt data center in Ohio and a Louisiana facility that could scale to 5 gigawatts, compressed margins, while Alphabet raised its 2026 capex guidance to as much as $205 billion and its Google Cloud backlog more than doubled year-over-year to $240 billion. The Stargate joint venture involving Oracle, OpenAI and others targets up to $500 billion in infrastructure investment by 2029, and Oracle's FY2026 capex reached $55.7 billion, more than doubling from the previous year.
