This week, Microsoft Corp. faces a more pointed debate around its stock: is artificial intelligence still its strongest growth engine, or could it end up undermining the Office and Azure lines that helped build its market cap? The latest pressure comes from TCI Fund Management, which slashed its Microsoft stake from 10% of its portfolio at the end of 2025 to just 1% by March’s close. Sir Christopher Hohn, in a note to investors, pointed to uncertainty about Microsoft’s future edge as AI advances rapidly.
MSFT’s been trailing the wider rally lately. On Friday, the stock slipped 1.34% to finish at $415.12, while both the Nasdaq and S&P 500 were setting fresh records to end last week.
The next hurdle isn’t a Microsoft earnings print. Instead, watch how big tech trades. April CPI lands Tuesday at 8:30 a.m. ET, with PPI up Wednesday, and April retail sales hitting from the Census Bureau on Thursday. If inflation comes in hot, rates could stay higher—usually a headwind for richly valued growth names.
TCI’s case hit a nerve, given Microsoft’s solid reputation as an AI play thanks to OpenAI, Azure, and Microsoft 365 Copilot. According to the Financial Times, Hohn flagged the potential for AI to disrupt existing Office routines and spark new productivity tools. The fund also pointed out “some risks in Azure,” the report said. TipRanks
Scale is where Microsoft flexes. Fiscal third-quarter revenue hit $82.9 billion, rising 18%. Microsoft Cloud pulled in $54.5 billion, up 29%, and Azure and related services jumped 40%. CEO Satya Nadella pointed to AI, noting the business has now crossed a $37 billion annualized run rate—soaring 123% year over year.
Investors may bristle at Microsoft’s rising outlays. The tech giant reported $31.9 billion in capital expenditures last quarter—money poured into data centers, chips, and the hardware that keeps its cloud running. It’s not slowing down: Microsoft said it’s on track to spend more than $40 billion in the current fiscal Q4. Chief Financial Officer Amy Hood defended the pace: She pointed to strong demand and product uptake, saying the company remains “confident in the return” on these heavy investments. microsoft.com
Azure stays front and center for investors. Microsoft’s forecast puts Azure growth between 39% and 40% this quarter, stripped of currency effects. But over at Google Cloud, Reuters says growth hit 63%. Microsoft’s exclusive on reselling OpenAI products has also ended, with Amazon now rolling out OpenAI’s latest models on its own cloud.
Copilot makes up the other line. In the quarter, Microsoft reported more than 20 million paid Microsoft 365 Copilot seats—momentum for its AI assistant, though that figure remains a fraction of Microsoft’s overall user base.
Microsoft remains in rally mode, though gains hinge heavily on earnings. Kristina Hooper, chief market strategist at Man Group, told Reuters that investors have “willed themselves to focus on only the positive.” State Street’s Michael Arone called earnings “the lifeblood of this rally.” Reuters
Investors could face unwelcome news on two fronts: inflation that leaves the Federal Reserve wary, and Microsoft ramping up AI spending before margins catch up. If Copilot adoption slows, component prices climb again, or there are clearer signs of AI workloads drifting to competitors, the uncertainty isn’t going anywhere.
Looking to the week ahead, MSFT’s direction could depend more on incoming inflation data than any single company update. If the macro backdrop stays friendly, bulls will likely lean on Azure’s almost 40% growth and that $37 billion AI run rate. Absent that, TCI’s exit hands bears an easy story: AI is the big draw—and potentially the big risk.
