Institutional and retail investors are reassessing the near-term investment case for artificial intelligence amid a surge in infrastructure outlays that could temper earnings growth and compression of valuation multiples, even though demand for AI services is intact.
Technology companies are committing substantial sums to cloud and AI infrastructure, a trend that analysts say will lift depreciation and lower free cash flow in the near term - effects that could slow earnings per share expansion and shrink the room for share repurchases that have supported equity valuations.
Market volatility this year has reflected those concerns. In the first half of 2026, Microsoft (NASDAQ:MSFT) declined about 20% and Oracle (NYSE:ORCL) fell roughly 27%, while Alphabet (NASDAQ:GOOGL) appreciated near 14%. Observers point to uncertainty about the returns on AI-related capital spending as a key driver of the swings.
At the same time, the economics of current investment are not uniformly questioned. Microsoft’s fiscal 2025 spending on cloud and AI infrastructure was about $65 billion, set against an annualised run rate of AI-related revenue of roughly $37 billion. Demand for AI compute continues to outstrip available capacity, and most large tech firms are able to fund these investments through operating cash flow.
Still, increased capital intensity is expected to reduce free cash flow and constrain buybacks, with notable implications for major cloud and ad-platform operators. Microsoft, Alphabet and Meta Platforms (NASDAQ:META) are singled out as companies where slower repurchases could combine with higher depreciation to make investors less willing to pay premium earnings multiples if AI revenue growth takes longer than expected to materialise.
Oracle is highlighted as a particularly high-risk example. Its investment programme - including work to support Project Stargate - could pressure cash flow and raise financing needs, according to the assessment. Separately, Nvidia (NASDAQ:NVDA) may face heightened competition over time as Microsoft, Alphabet and Amazon (NASDAQ:AMZN) develop proprietary AI chips aimed at improving infrastructure efficiency.
Despite these headwinds, the prevailing view in this analysis is that current AI spending can be rationalised on economic grounds. The central issue for investors is whether subsequent gains in revenue, profit margins and earnings will ultimately justify the scale of present-day capital deployment.
Market moves noted in the discussion:
- Microsoft - down about 20% in H1 2026
- Oracle - down about 27% in H1 2026
- Alphabet - up about 14% in H1 2026
- Other quoted moves include Nvidia, Meta Platforms and Amazon in the context of competitive and buyback dynamics
Investors weighing AI exposure must now balance the technology-driven revenue opportunity against the near-term financial trade-offs of heavier capital expenditure, especially where buybacks and free cash flow have supported past valuations.
