Investors Reassess Big Tech's AI Spending Spree Amid Earnings Concerns, ING Says

Investors are beginning to scrutinize the immense cost of the artificial intelligence boom, with a new analysis warning that surging infrastructure spending could weigh on corporate earnings and valuations. While demand for AI services remains robust, rising capital expenditures may slow profit growth and limit shareholder returns, according to a report from ING.

The Capital Expenditure Challenge

The long-term outlook for large technology companies remains positive, driven by the broad adoption of AI. However, the massive investments required to build out AI infrastructure are expected to increase depreciation costs, which could slow earnings per share (EPS) growth.

Furthermore, this heightened spending is anticipated to reduce free cash flow. This would limit the capacity for share repurchase programs, which have been a key driver supporting equity valuations for companies like Microsoft (NASDAQ:MSFT), Alphabet (NASDAQ:GOOGL), and Meta Platforms (NASDAQ:META). According to ING, investors may become less willing to pay premium earnings multiples if significant AI revenue takes longer than expected to materialize.

Company-Specific Pressures

While most large tech firms can finance these investments through operating cash flow, the scale is substantial. Microsoft's plan to invest approximately $65 billion in cloud and AI infrastructure in fiscal 2025 is viewed as economically justified, given its annualized AI revenue of roughly $37 billion. Still, the spending will likely constrain its buyback activity.

ING's analysis highlighted Oracle (NYSE:ORCL) as a higher-risk case, suggesting its investment program could significantly pressure cash flow and increase its need for external funding. Meanwhile, market leader Nvidia (NASDAQ:NVDA) may face stronger competition over time as major customers like Microsoft, Alphabet, and Amazon (NASDAQ:AMZN) develop their own proprietary AI chips to improve efficiency.

Market Volatility and Outlook

This uncertainty over the return on AI investments has contributed to sharp swings in technology stocks this year. In the first half of 2026, Microsoft shares fell 20% and Oracle dropped 27%, while Alphabet gained 14%, according to the report.

Despite the risks, current spending levels are seen as fundamentally sound, as demand for AI computing continues to outstrip available capacity. The key question for investors, ING concludes, is whether future revenue growth and profit margins will ultimately justify today’s level of investment.
