Alphabet, Microsoft, Amazon, Meta gauntlet

Alphabet, Microsoft, Amazon and Meta all report earnings after the close on Wednesday, April 29, putting the AI trade through its biggest test of 2026. (reuters.com) (abc.xyz) (ir.aboutamazon.com) (investor.atmeta.com) The four companies are the market’s biggest “hyperscalers,” the cloud groups building the data centers, chips and servers that run artificial intelligence services. Reuters reported they are expected to spend more than $600 billion this year on data centers and other AI infrastructure. (reuters.com) Wall Street is watching four basic numbers: revenue growth, profit margins, capital spending guidance and signs that cloud customers are still buying more AI capacity. Business Insider said those are the pressure points across all four reports. (businessinsider.com) Microsoft’s report is a readout on Azure, its cloud unit, after investors spent months asking whether demand is outrunning supply and whether the company will raise spending again. CNBC said Microsoft may lift capex guidance as it keeps expanding AI capacity. (cnbc.com) Alphabet faces a similar question at Google Cloud, with investors looking for proof that AI products are adding sales fast enough to justify heavier infrastructure costs. Alphabet said its first-quarter 2026 call starts at 4:30 p.m. Eastern on April 29. (businessinsider.com) (abc.xyz) Amazon’s report will show whether Amazon Web Services can keep translating AI demand into faster cloud growth while the company funds a broad buildout of computing capacity. Amazon said its first-quarter 2026 earnings call begins at 5:30 p.m. Eastern on Wednesday. (businessinsider.com) (ir.aboutamazon.com) Meta is the outlier because most of its money still comes from advertising, not cloud computing, but investors are judging whether ad sales can keep covering a larger AI bill. CNBC reported last week that Meta plans to cut about 10% of its workforce, or roughly 8,000 jobs, as it ramps AI investment. (cnbc.com) The setup turned more tense after U.S. stocks fell on Tuesday, April 28, with the Nasdaq and S&P 500 pulling back as investors worried about AI growth and waited for the earnings wave. Reuters said the market had already been questioning whether AI spending can keep producing returns fast enough. (reuters.com 1) (reuters.com 2) Another complication is cost. CNBC reported that oil prices, helium supply disruptions and a tighter memory market have all raised the price of building and running AI infrastructure since the Iran war began. (cnbc.com) OpenAI also hangs over the day even though it does not report public earnings. CNBC said the company’s private valuation has climbed above $850 billion, and its revenue trajectory is now being treated by investors as a proxy for the broader AI boom. (cnbc.com) By Wednesday night, investors will have four answers at once: whether AI demand is still accelerating, whether margins are holding up, and whether Big Tech is ready to spend even more.
