Microsoft told investors Wednesday it will spend $190 billion on capital projects in 2026, a 61 percent increase from 2025, and Alphabet on the same evening lifted its own 2026 capex range to as much as $190 billion. A few hours later in Seoul, Samsung Electronics reported a more than 750 percent jump in first-quarter operating profit, a record. The combined 2026 capital plans of the four U.S. hyperscalers and their largest memory supplier now exceed $700 billion.

The scale resets the financial assumptions underwriting the AI cycle. Microsoft Chief Financial Officer Amy Hood told analysts that $25 billion of the 2026 outlay reflects higher component prices from the global memory shortage that lifted Samsung's chip-division profit from about 1 trillion Korean won a year ago to 53.7 trillion won in the most recent quarter. The hyperscalers are spending faster than analysts had modeled, and the suppliers feeding them are charging more.

What Microsoft said

Microsoft reported revenue growth of 18 percent for the quarter ended March 31 and net income of $31.78 billion, or $4.27 a share. Azure and other cloud services grew 40 percent, above StreetAccount's 39.3 percent consensus. Capital expenditures and finance leases reached $31.9 billion in the quarter, up 49 percent. Hood's $190 billion 2026 capex call topped the Visible Alpha consensus of $154.6 billion by more than $35 billion. "We continue to evolve how we operate, to increase our pace and agility," Hood said, adding that head count will decline year over year in the calendar year ending June 2027. Annualized AI revenue across Azure and Microsoft's own tools now stands at $37 billion, up 123 percent.

Alphabet's parallel bet

Alphabet posted 20 percent revenue growth, its highest quarterly rate since 2022, on Google Cloud growth of 63 percent. Capital expenditures hit $35.7 billion in the quarter. The company raised its 2026 capex range to $180 billion to $190 billion from $175 billion to $185 billion, and Chief Financial Officer Anat Ashkenazi told analysts that 2027 spending would significantly increase from there.

"Our enterprise AI solutions have become our primary growth driver for cloud for the first time in Q1," Chief Executive Sundar Pichai said on the earnings call. "We are compute constrained in the near term," Pichai said, adding that cloud revenue would have been higher if the company had been able to meet demand. The cloud backlog is now $460 billion.

Samsung's eightfold quarter

Samsung's first-quarter profit, which exceeded its full-year 2025 figure of 43.6 trillion won, came almost entirely from chips. The Device Solutions division produced more than 90 percent of total operating income, with margins above 70 percent — higher than Nvidia or Taiwan Semiconductor Manufacturing in the same quarter, according to Counterpoint Research analyst Jeongku Choi.

"Memory is firmly establishing its independent position as the deciding factor in the success or failure of AI infrastructure," Choi said. A Samsung executive on the earnings call said the company's available memory supply is expected to remain far behind customer demand. "Our demand fulfillment rate is now at a record low, and unlike previous years, customers who are concerned about supply shortages are actually bringing forward their demand for 2027," the executive said. Samsung said in February it became the first to mass-produce HBM4 memory, the chip earmarked for Nvidia's next-generation Vera Rubin architecture, though SK Hynix retained 57 percent of the HBM market in the final quarter of last year.

One bucket

All three reports here come from CNBC's wire-style desk; today's dossier contains no lean-left or lean-right framing of the same earnings, and the bull and bear cases that partisan business outlets typically supply are absent. Within the wire account itself, Microsoft stock ended Wednesday down 12 percent for the year on concern its AI investments will not earn out, and on Monday the company ended its exclusive cloud arrangement with OpenAI. "We have a frontier model, royalty-free, with all the IP rights that we will have access to all the way to '32, and we fully plan to exploit it," Chief Executive Satya Nadella said.
