Big tech’s $16 trillion earnings week begins: Alphabet, Amazon, Meta, Microsoft report today and Apple tomorrow – here's what investors are watching

Alphabet, Amazon, Meta, Microsoft earnings today: A crucial week has unfolded for Wall Street, as some of the world’s biggest technology companies prepare to report earnings that could shape the direction of markets.

Big Tech Earnings Season Becomes a Key Test for AI Momentum

Despite ongoing tensions from the war in Iran and rising oil prices, the S&P 500 has climbed to record highs, largely carried by its biggest tech names. Now, investors are watching closely to see if those same companies can justify the rally with strong results.

Nearly $16 Trillion Worth Tech Giants Dominate S&P 500 Performance

Companies including Alphabet, Microsoft, Amazon, and Meta Platforms are set to report on Wednesday, followed by Apple a day later, which is already in the spotlight after announcing it plans to replace CEO Tim Cook with John Ternus. Together, these firms are worth nearly $16 trillion, accounting for about a quarter of the S&P 500 Index, as per a Bloomberg report.

Alphabet, Amazon, Meta, and Microsoft Earnings in Focus Today

The real focus isn’t just on what these companies earned, but what they say about the road ahead. Investors are looking for clues about business momentum, future demand, and especially how much they plan to spend on AI.

Nvidia Earnings Ahead Seen as Key AI Market Catalyst

There’s more to come. Nvidia, now valued above $5 trillion, will report in mid-May, and its update is still seen as one of the most important for understanding where AI and the market are headed, as per an Investopedia report.

These companies are also the biggest spenders on AI infrastructure. Their investments have fueled a surge in demand for chips and memory, turning semiconductor and storage companies into some of the most sought-after trades on Wall Street.

Right now, investors aren’t just focused on traditional business performance like e-commerce, advertising, or software. What matters more is how much these companies are spending on AI, and whether that spending is actually turning into meaningful revenue growth, as per a Bloomberg report. That’s because these massive investments are starting to cut both ways.

AI Spending Surge Drives Semiconductor and Chip Stock Rally

On one side, there’s clear momentum. An entire supply chain depends on Big Tech continuing to spend. The Philadelphia Semiconductor Index has jumped 32% in April, riding an 18-session winning streak and heading toward its best month since February 2000, as per a Bloomberg report. Semiconductor and storage-related companies now make up the top 11 performers in the Nasdaq 100 this year, largely driven by rising expectations around AI-related revenue.

OpenAI Updates Add Fresh Doubts to AI Growth Narrative

But there’s also growing concern. Investors are starting to question how long it will take for these huge investments to pay off. Reports that OpenAI missed internal targets for new users and revenue have added to that uncertainty, raising doubts about whether such large infrastructure spending can be justified in the near term. Following that news, the Philadelphia Semiconductor Index dropped 3.6%, marking its worst day in a month, as per the Bloomberg report.

What Big Tech Guidance Means for the Next Market Move

Ameriprise's chief market strategist, Anthony Saglimbene explained that, “If capex is paired with positive revenue, measurable revenue, and outlooks that show that earnings and revenue are being guided higher, then I think increased capex will be OK for the stocks,” adding “But if we see any slippage on the outlooks, that will lead to more volatility and pressure the S&P 500,” as quoted by Bloomberg.

Dan Ives' Outlook: Alphabet, Amazon, Meta, Microsoft, Apple Earnings Expectations

“It’s a ‘prove it’ moment for AI,” according to Wedbush tech analyst Dan Ives, as companies prepare to report today and tomorrow, based on his Wednesday note, as reported by Investopedia.

He highlights what investors should be watching across Big Tech:

Apple: Ives calls this a “monumental” conference call, especially with Cook leaving as CEO. He says investors will be laser-focused on Cook’s comments around his departure and any clues about Apple’s long-awaited AI strategy under Ternus.

Alphabet: He expects another strong beat, arguing the Street continues to underestimate the growth potential of Google Cloud, AI-powered Search, and YouTube heading into 2026.

Amazon: Ives also expects a strong beat, saying investors are still underestimating how quickly AWS is reaccelerating amid a supply-constrained AI demand environment.

Meta: He sees another strong beat here as well, pointing to what he describes as a growing flywheel effect from AI-powered ad monetization flowing into results. In his view, this report will reinforce Meta as one of the clearest AI monetization stories in Big Tech.

Microsoft: Ives expects solid results, saying Microsoft remains in the lead in the AI revolution, with FY26 shaping up as a true inflection point as more CIOs line up enterprise deployments. He also notes the Street is underestimating Azure’s growth story.
