Microsoft’s $146B AI spending spree is spooking investors — and could lead to its worst quarter since 2008

Investors are worried about startups like OpenAI and Anthropic replacing Microsoft's core productivity apps.

Microsoft has ramped up its efforts in the generative AI space over the past few years, especially after making its first investment in OpenAI back in 2019. While AI seems like the hot thing in tech right now, it's unclear whether the software giant's deep integration of Copilot across its tech stack is actually paying off.

And now, a new report by Bloomberg suggests Microsoft could be facing its worst quarter since the 2008 financial crisis if it continues blowing money on AI that isn't meeting investor expectations for returns.

For context, Microsoft’s stock fell 25% in Q1 FY26, putting the company on track for its steepest quarterly loss since the 27% drop in late 2008. But it isn't budging. Microsoft is doubling down on AI, with plans to invest about $146 billion in infrastructure in 2026, which is approximately twice last year’s $88 billion.

Earlier this year, Microsoft announced its financial earnings report for FY26 Q2, reporting $81.3 billion in revenue (up 17% YoY) and $38.3 billion in operating income (up 21% YoY). While these numbers might seem impressive, investors have raised concerns about the software giant's spending on data centers and AI infrastructure.

Microsoft CEO Satya Nadella indicated that the company's AI spending is actually paying off, further revealing that Copilot's daily user base has grown “nearly 3x year-over-year.” However, only 3.3% of Microsoft 365 and Office 365 users who interact with Copilot actually pay for it.

The tech giant could be setting itself up for failure with its heavy investment in AI, as investor interest is waning, and they become hesitant to commit funds to Microsoft’s exorbitant AI initiatives.

Some have openly voiced concerns that AI startups like OpenAI and Anthropic are developing agents that could one day replace established productivity suites such as Microsoft 365.

Speaking to Bloomberg, Jonathan Cofsky of Janus Henderson suggested that "rather than paying Microsoft, more customers may choose to go directly to AI vendors."

Is Microsoft playing the long game in AI?

While Microsoft's exorbitant spending on AI isn't exactly paying off right now, Wall Street analysts are seemingly optimistic that the company's strategy will pay off in the long-term.

Jake Seltz, a portfolio manager at Allspring Global Investments, indicated:

“I think the stock has a lot of long-term value. Its AI strategy will ultimately be vindicated, and I think it is largely insulated from the biggest AI disruption fears. In the meantime, those concerns are creating an opportunity, especially if you’re willing to have some patience.”

Interestingly, Microsoft CEO Satya Nadella recently indicated that AI must prove its worth in the real world, or big tech could lose public support and social permission to burn electricity unless it offers something useful.

Right now, the tech giant is seemingly reevaluating its AI strategy, well, at least in its offerings like Windows 11, by reducing where Copilot and AI experiences appear, like those integrations found in Notepad and Paint.
