Is now a good time to expect rising AI spending to continue boosting stock market profits?
Major U.S. hyperscalers are set to reach $1.2 trillion in capital spending by 2027. This level of investment creates a sensitivity where a $250 billion deviation in spending will shift S&P 500 earnings growth by 6 percentage points.
Why it matters
AI investment is a significant driver of corporate earnings growth, accounting for nearly 50% of the S&P 500 earnings-per-share expansion in 2026. Understanding these spending levels is vital for gauging the sustainability of broad market performance.
Hyperscalers are projected to spend $800 billion in 2026, marking a 94% increase over 2025 levels. Total capital expenditure is expected to continue rising to $1.4 trillion by 2028.
The details
While AI-related spending generates immediate revenue for chip and infrastructure suppliers, the eventual earnings lift for companies is tempered by depreciation costs recorded over time. Market growth is projected at 11% for both 2027 and 2028, though earnings growth is expected to eventually decelerate as AI investment shifts to a marginal drag.
Timeline
2025 marks the baseline for hyperscaler spending calculations.
2026 hyperscaler spending is projected to reach $800 billion.
2027 spending sensitivity impacts S&P 500 earnings by 6 points.
2028 hyperscaler spending is projected to reach $1.4 trillion.
The Tech Race
This massive scale of investment in AI infrastructure reflects a rapid acceleration in the tech industry beyond historical hardware cycles. It positions major U.S. hyperscalers at the center of a capital-intensive race that is fundamentally reshaping the composition of broad market earnings.
For investors, these projections highlight how heavily S&P 500 earnings depend on the massive, ongoing infrastructure spending of a few major tech firms. Monitoring these spending reports is essential for understanding the stability of long-term market growth and portfolio valuations.
The takeaway
While massive AI investment is currently boosting corporate earnings, the future trajectory suggests a eventual deceleration as equipment depreciation catches up. Investors should consider how this reliance on high capital expenditures might impact market volatility in the coming years.
