As power becomes a larger share of hyperscale operating costs, a sustained spike in crude prices risks compressing margins just as big tech firms ramp up record capex for AI infrastructure.
Gary Black's Warning
Investment advisor Gary Black shared insights into how high oil prices hurt companies by raising energy costs.
Brent crude increased by +27% last week, the largest weekly gain on record according to Dow Jones.
Short-term market swings don't have a lasting impact unless they affect the real economy in some way. There are three main ways high oil prices affect the real economy.
"It also influences the many tech companies that are building out energy-intensive AI data centers. When business expenses go up, and companies can't pass those increases along as price increases, it cuts into corporate earnings, which impact stock prices," Black said in a social media post.
That logic now extends directly to the hyperscalers leading the AI build‑out.
Why $120 Oil Matters Now
Brent has already spiked toward four‑year highs on geopolitical shocks, underscoring how fragile energy supplies look at three‑digit prices.
At the same time, data‑center electricity use is exploding, with U.S. facilities consuming over 4% of national power in 2024 and projected to more than double by 2030, making electricity the dominant operating expense.
AMZN, GOOGL, MSFT at Risk
Amazon CEO Andy Jassy has highlighted AWS’s addition of gigawatts of new capacity, including multi‑billion‑dollar campuses that materially lift the company's energy bill.
That means higher oil‑linked power prices flow straight through to AWS margins unless Amazon can quickly reprice cloud and AI services.
Alphabet has already cited higher technical infrastructure costs, including depreciation and energy costs, as a factor in Google Cloud’s profitability, even before an extended $100‑plus oil regime.
With capex expected to surge further to support Gemini and other AI workloads, each incremental cent per kilowatt‑hour matters more.
Microsoft is building multi‑gigawatt AI campuses—such as its planned 2‑GW Wisconsin site—locking in a structurally higher power demand. While software efficiencies can offset part of the hit, elevated energy costs at scale could shave points off cloud margins just as investors are paying peak multiples for AI growth.
If oil holds above $100, markets may have to re‑rate the AI leaders not only on the top‑line opportunity, but on a structurally higher cost base that erodes the earnings leverage underpinning today's valuations.
