U.S. corporate earnings season gathers steam this week as Alphabet and Intel prepare to report results that could sway the market-leading AI trade, with investors testing whether corporate profits can justify high expectations even as uncertainty over the Iran war continues to weigh on sentiment.
Where the Market Stands
The S&P 500 slipped Friday to post a weekly decline, dragged down by a steep pullback in high-flying semiconductor shares. Even so, the benchmark index remained up roughly 9%–10% for 2026 and sat only about 2% below its early June record high — a sign that despite recent volatility, the broader rally powering U.S. equities this year remains largely intact heading into this pivotal earnings stretch.
What's at Stake for Alphabet
Alphabet's results are being closely watched as a bellwether for the broader AI infrastructure buildout that has powered much of the market's gains this year. Kevin Mahn, president and chief investment officer at Hennion & Walsh Asset Management, warned that if Alphabet signals any pullback in its forecasted AI spending, "you could see ripple effects across the entire AI ecosystem" — underscoring just how tightly investor sentiment across the tech sector has become tied to the spending plans of a handful of mega-cap companies.
Why Intel and Chipmakers Carry Extra Weight This Cycle
Results from semiconductor firms Intel and Texas Instruments carry particular significance given the sector's dramatic run this year — and its equally dramatic recent reversal. The Philadelphia Stock Exchange Semiconductor Index ended last week down more than 20% from its late-June record high, confirming the sector has entered a bear market. That pullback puts added pressure on this week's chip earnings to either validate the AI-driven rally that carried the group to those highs, or add to growing concerns that the trade has gotten ahead of itself.
The Broader Earnings Backdrop
The stakes extend well beyond any single company. Analysts expect S&P 500 earnings to climb roughly 25.7%–26% for the second quarter, according to LSEG IBES data — an unusually strong projected growth rate that has provided a key pillar of support for investor confidence even as geopolitical headlines have grown louder. State Street Global Advisors chief investment strategist Michael Arone captured the market's somewhat dissonant mood, noting that continued headlines have left investors puzzled as to why stocks keep climbing toward new records despite the steady stream of unsettling news.
The Iran War Wildcard
Much of that unease traces back to the ongoing conflict between the U.S. and Iran, which has kept energy markets on edge for months. Many investors reportedly expect the war to be relatively short-lived, but remain wary that renewed escalation could push energy prices back toward the highs seen earlier in the conflict, reigniting inflation fears that could complicate the Federal Reserve's policy path and undercut the earnings growth investors are counting on this quarter.
Why This Week Matters
Taken together, this week's results from Alphabet and Intel — set against a backdrop of a wobbling semiconductor sector, historically strong projected earnings growth, and an unresolved Middle East conflict — represent one of the clearest tests yet of whether the AI-driven rally that has defined 2026 markets can hold up under real scrutiny, or whether the recent pullback in chip stocks is an early signal of broader cracks forming beneath the market's record-adjacent highs.
What's Next
Investors will be parsing both companies' commentary on AI capital expenditure plans, demand trends, and forward guidance for clues about the durability of the broader AI investment cycle. With the Philadelphia Semiconductor Index already in bear-market territory and the S&P 500 sitting just below record highs, this week's results are likely to set the tone for how markets navigate the rest of a Q2 earnings season already shadowed by geopolitical risk.
