Q1 2026 Earnings Season Preview: Oil Shocks, AI Spending, and the Stocks to Watch

The S&P 500 is expected to deliver 13.2% earnings growth this quarter — one of the strongest prints since 2022. But behind that headline number lies a market torn between AI-fueled optimism and oil-driven anxiety. The next two weeks of earnings reports will tell us which narrative wins.

Why This Earnings Season Is Different

Every earnings season matters, but Q1 2026 carries unusual weight. Three forces are colliding simultaneously, creating a setup that will define the market's direction for the rest of the year.

First, oil prices have surged from $55 to over $110 per barrel in just three months due to the U.S.-Iran conflict. This is the kind of input cost shock that can vaporize corporate margins overnight — especially for airlines, logistics companies, and manufacturers.

Second, AI capital expenditure continues to accelerate. The hyperscalers — Microsoft (MSFT), Alphabet (GOOGL), Amazon (AMZN), and Meta Platforms (META) — are collectively spending over $200 billion annually on AI infrastructure. Investors need to see evidence that this spending is translating into revenue growth, not just higher costs.

Third, the Federal Reserve's rate-cutting cycle may be in jeopardy. With oil pushing inflation expectations higher, the March CPI report due Thursday could force the Fed to pause. That would change the entire calculus for rate-sensitive sectors like real estate, utilities, and small caps.

The Earnings Calendar: Key Dates

Here is a breakdown of the most important earnings reports over the next two weeks:

Delta Air Lines: The Canary in the Oil Mine

Delta Air Lines (DAL) reports Wednesday morning, and it might be the most consequential airline earnings report in years. When oil was trading at $55, Delta's fuel hedging strategy looked brilliant. At $110, even the best hedges can only cushion so much pain.

Analysts have slashed EPS estimates by 11% over the past month, landing on a consensus range of $0.62 to $0.64. For context, Delta earned $0.45 per share in Q1 2025, so the street is still expecting growth — but that expectation has narrowed dramatically.

The key metrics to watch beyond the headline EPS number are fuel cost per gallon (anything above $3.20 signals serious margin compression), revenue per available seat mile (RASM), and full-year guidance. If Delta cuts its 2026 outlook, expect the entire airline sector — including United Airlines (UAL) and Southwest Airlines (LUV) — to sell off in sympathy.

Constellation Brands: Reading the Consumer

Constellation Brands (STZ) is in the final stages of a painful portfolio transformation. The company has divested several lower-end wine and spirits brands to go all-in on its Mexican beer portfolio, headlined by Modelo Especial and Corona.

Analysts expect what could be Constellation's lowest quarterly earnings in five years. But the story here is not about the past — it is about whether the beer-centric strategy is working. Modelo Especial has been the fastest-growing beer brand in the United States for three consecutive years. If that momentum continues, the stock could rerate significantly.

Watch for commentary on consumer trade-down behavior. With gas prices elevated and inflation sticky, there are signs that consumers are shifting from premium spirits to more affordable beer options — which could actually benefit Constellation's repositioned portfolio.

BlackRock: The Private Credit Stress Test

BlackRock (BLK) reports on April 14, and this quarter's report is about far more than asset management fees. As the world's largest asset manager with over $11 trillion in assets, BlackRock's results are a referendum on the health of global capital markets.

The spotlight will be on private credit, which is facing its first real stress test of a full credit cycle. Following a string of leveraged loan defaults in late 2025, investors want to know: are the losses contained, or is this the beginning of something bigger?

BlackRock has been aggressively expanding its private markets business, most recently through its acquisition of Global Infrastructure Partners. CEO Larry Fink has called private credit "the most exciting growth opportunity in asset management." This earnings call will test that thesis in real time.

JPMorgan Chase: The Banking Barometer

JPMorgan Chase (JPM) is always the first major bank to report, and its results set the tone for the entire financial sector. CEO Jamie Dimon has been increasingly vocal about geopolitical risks, calling the current environment "the most dangerous in decades."

Key metrics to watch include net interest income (NII) — has it peaked now that rate cuts are on pause? Trading revenue is another focus, as volatility should be a tailwind. Loan loss provisions will signal whether JPM sees credit deterioration ahead. And investment banking fees will show whether the M&A and IPO recovery that began in late 2025 is still alive.

Jim Cramer flagged JPMorgan on Monday as a stock that could see "dramatic moves" following recent corporate changes. The bank's stock has outperformed the S&P 500 by 8 percentage points year-to-date, but that premium valuation leaves little room for disappointment.

The AI Earnings Bonanza: Later in April

The real fireworks come later in the month when the mega-cap tech companies report. GOOGL reports April 24, followed by MSFT, META, and AMZN in late April and early May.

The big question: is AI spending translating into revenue? NVDA has been the market's AI bellwether, but its next report is not until late May. In the meantime, the hyperscalers' earnings will provide the best window into AI demand trends.

Morgan Stanley's 2026 outlook argues that AI is not just a tech story anymore — it is spreading into banks, healthcare, logistics, and utilities. If the earnings data confirms that thesis, the broadening of market leadership beyond the "Magnificent Seven" could accelerate.

Sectors to Watch: A Scorecard

Based on the earnings setup, here is how the major sectors stack up heading into reporting season:

How to Position Your Portfolio

For investors trying to navigate this earnings season, the playbook depends on your time horizon and risk tolerance. Understanding fundamental analysis is critical during periods like this, when headline noise can obscure underlying business quality.

Short-term traders should focus on the pre-earnings positioning. Stocks with the most extreme analyst estimate revisions — both up and down — tend to see the largest post-earnings moves. DAL and STZ have both seen significant downward revisions, creating a low bar that could be easier to beat.

Long-term investors should use any earnings-driven volatility as a buying opportunity for quality companies trading at reasonable valuations. The best investment strategies during earnings season involve having a watchlist ready and knowing what price you are willing to pay.

The Bottom Line

Q1 2026 earnings season arrives at a critical inflection point. The 13.2% expected growth rate is impressive, but the range of outcomes has rarely been wider. Oil at $110 is a headwind for most sectors, AI spending is a tailwind for a select few, and the Fed's next move remains uncertain.

The companies reporting over the next two weeks — DAL, STZ, BLK, JPM, and the rest — will not just reveal their own performance. They will tell us whether the 2026 bull market has real earnings support or is running on borrowed time.
