U.S. Oil is up more than 70% from a year ago. But Wall Street is betting corporate profits will sprint ahead anyway.

Wall Street's rosy math

Wall Street's earnings consensus is sprinting ahead; it's fast and, to many, probably too optimistic. LSEG's aggregate data points to 13.9% year-on-year growth in first-quarter earnings, and projections for the next three quarters climb into the 20% range, according to Tajinder Dhillon, head of earnings research at LSEG. Those figures are unusually large — they would be the strongest annual corporate‑profit gains since 2018, if you set aside the pandemic year of 2021.

Yet the market's price moves are telling a different story. The Nasdaq is trading above its level from before the Iran war began on February 28, and the S&P 500 isn't far behind. It's almost as if the last six weeks didn't happen.

That gap matters. If companies are expected to deliver those growth rates, they need revenue and margins to keep accelerating even as outside pressures pile up.

Oil, inflation and the consumer mood

The headline risk is energy. The Consumer Price Index release for March showed gasoline surged roughly 21% in the month, while diesel and other motor fuels rose more than 30% — record moves. That's not trivia. Fuel costs feed straight into household budgets and firms' expense lines. When filling up the tank gets notably more expensive, people buy fewer discretionary goods. Employers face higher transport and input costs.

Margins get squeezed unless firms can raise prices further.

Consumers already look worn out. The University of Michigan's consumer sentiment survey hit a record low in its latest reading. That kind of mood matters because it predicts spending — and spending is nearly two-thirds of U.S. GDP.

At the same time, Bank of America economists have adjusted their outlook. They've trimmed their 2026 GDP forecast by 50 basis points to 2.3% and raised their core personal consumption expenditures inflation projection by 70 basis points to 3.1%. Those moves reflect a belief that higher energy costs and geopolitical risk will shave growth while keeping inflation firmer.

Where the earnings upside has to come from

Hitting the consensus would require several things to fall into place simultaneously. First, companies would need to keep passing higher input costs to customers without triggering demand destruction. Second, productivity gains or cost cuts would have to offset part of the bill. Third, revenue growth would need to accelerate in key sectors.

That's a steep ask. Some parts of the market could deliver. Energy producers, for example, will likely report stronger revenue as oil prices rise. But other sectors face harder choices. Industrials and transport firms carry larger fuel bills, and consumer-facing retailers could see sales slip if households pull back.

Dhillon at LSEG flags the arithmetic: consensus forecasts for the remaining three quarters call for roughly 20%, 22% and 19.9% earnings growth. Meeting that requires profit margins to hold up or improve even as costs ratchet higher.

Historically, those kinds of gains haven't been common outside of unusual years.

Why markets might be betting on tech and AI

One reason stocks haven't fallen is investor faith in technology — especially artificial intelligence. The narrative that AI will unlock new revenue streams and cost efficiencies has resiliency built in. Investors have repeatedly rewarded firms that position themselves as AI leaders, and that optimism has supported valuations.

Even so, AI won't automatically protect firms from every cost shock. It helps where software and automation can substitute for labor or create new high-margin products. It won't fully neutralize a wave of higher commodity costs or a sustained consumer pullback. That said, if a handful of large tech firms report oversized profit beats, index-level earnings could look healthier even while smaller firms struggle.

How the reporting season could play out

When companies start reporting, the street will look for two things: topline health and margin resilience. Firms that can dodge fuel-driven margin erosion and show credible pricing power will likely get rewarded. Those that cite cost pressures, weaker volumes or guidance cuts will face pain.

Investors should watch sector-level trends closely. Energy and materials will probably show clear benefits from higher commodity prices. Consumer discretionary, transport, and some industrial names could show strain. Financials may get mixed results — loan growth and net interest margins matter, but so do loan-loss provisions if growth slows.

What management teams say going forward will be revealing. If management teams bake in higher fuel or freight costs and still forecast accelerating profits, they'll need to show how. If they warn of headwinds, estimates across the street will likely be repriced quickly.

Historical context and stakes

Big upward revisions to consensus earnings are rare during periods of rising inflation and geopolitical shock. The last time corporate profits posted comparable, broad-based growth was before the global shocks of recent years. Investors who assume current estimates are a safe baseline risk underestimating how persistent costs could hollow out margins.

Market resilience so far reflects both a narrow leadership in mega-cap tech and a belief that central banks will tame inflation without tipping the economy into recession. But central-bank policy is another wild card. If inflation proves stickier than expected, interest-rate expectations could shift and valuations would come under pressure — and that would matter for growth-stock-heavy indexes like the Nasdaq.

Overall, the first-quarter season will be a real test of whether Wall Street's optimism is earned. Companies facing direct hits from higher fuel and energy prices will offer the clearest signals. Others will need to explain where their earnings will come from — and fast.
