Alphabet's quarterly report on Wednesday will command Wall Street's attention as investors look for proof that the corporate profit engine can keep humming while the U.S. stock market tries to shrug off uncertainty over the Iran war. The Google parent is the third-largest U.S. company by market value at $4.3 trillion, and its spending on billions of dollars in data centers and AI infrastructure has become one of the central engines of this year's market rally.
The numbers are doing the heavy lifting. The S&P 500 was lower for the week as of Thursday, but it remained not far from record highs after a rally that has lifted the benchmark index 10% in 2026. Investors are now leaning on the just-underway second-quarter earnings season to keep the whole setup from wobbling, with S&P 500 earnings projected up a whopping 25.7% in the period, according to LSEG IBES data. That is the kind of expectation that turns quarterly reports into pressure tests for the entire market machine.
Who Has the Power
Wall Street's biggest names are setting the terms. Alphabet is one of the heavyweight "Magnificent Seven" stocks that have driven U.S. equities higher for much of the bull run that has lasted nearly four years. Reuters said the company is also an AI "hyperscaler," and Kevin Mahn, president and chief investment officer at Hennion & Walsh Asset Management, said if Alphabet announces "any type of pullbacks with respect to the spending that they're forecasting around AI, you could see ripple effects across the entire AI ecosystem."
That is the hierarchy in plain sight. One giant company's spending plans can shake semiconductors, indexes, and the broader trade built around AI. Reuters said AI capital spending has been at the heart of this year's market rally, driving huge gains for semiconductors and other companies benefiting from the massive outlays. The market isn't just watching earnings. It's watching whether the bosses of the biggest firms keep pouring money into the next round of speculation.
Michael Arone, chief investment strategist at State Street Investment Management, said, "Headlines continue to raise anxiety and leave investors scratching their heads wondering why the market continues to reach new heights," and added, "And the reason it does is because the fundamentals have been resilient, and the earnings continue to be outstanding."
Who Gets Crushed
The pressure doesn't sit evenly. Reuters said the Philadelphia SE Semiconductor index remains up about 68% in 2026; Intel shares have soared over 160%, while Texas Instruments has gained 68%. Those gains have made chip stocks a giant force inside the indexes, which means their swings can drag the market's direction around with them. Leveraged products tied to the semiconductor space are also "amplifying on both the upside and the downside," Arone said.
That kind of amplification is great for the people selling the trade. It can be brutal for everyone else caught in the churn. Reuters said chip stocks have seen huge swings as investors questioned whether the high-flying trade has run too far. Tepid market reactions to strong reports this period from foreign companies Samsung Electronics and Taiwan Semiconductor show just how inflated the expectations have become for the semiconductor industry.
Tesla, another Magnificent Seven company, is also set to post results in the coming week. Other high-profile results include American Express, Philip Morris International and defense contractor RTX, with more than 80 S&P 500 companies expected to report. Major U.S. banks kicked off the reporting season this week, posting earnings boosted by fees for advising on mergers and acquisitions and surging trading revenue. The profits keep flowing upward. The costs, as usual, get spread around.
What They're Calling Stability
Wall Street was still bracing for developments in the Middle East to cause day-to-day market swings, following a recent escalation of the nearly five-month-old U.S.-Israeli war with Iran. Many investors expect the war to be relatively short-lived, but they remain wary that renewed tensions could boost energy prices up to levels they reached following the start of the war, inflaming inflation fears. That's especially an issue ahead of the Federal Reserve's meeting at the end of July.
Pricing in fed funds futures indicate expectations the U.S. central bank will raise interest rates in the coming months to bring down inflation that is above the Fed's 2% annual target. Cooler-than-expected data this week on U.S. consumer and producer prices calmed some fears the Fed could raise rates at this month's meeting. Eric Kuby, chief investment officer at North Star Investment Management, said, "The macro data has painted a picture of a steady economy with some improvement in inflationary pressure."
That steady economy is the one the market wants to believe in. It rests on earnings growth projected at 25.7%, on a $4.3 trillion tech giant's spending plans, on chip stocks that can whip indexes around, and on a war economy that keeps investors glued to energy prices and central bank signals. The whole arrangement depends on confidence staying intact. When it cracks, the people at the bottom don't get a vote. They get the bill.
