Market narrative: AI and the rebound

The rebound in United States stocks has been led by technology again, with investors treating artificial intelligence spending as a build-out story, not just a consumer app trade. (reuters.com) On April 15, the Nasdaq Composite hit an intraday record and closed at a record for the first time since October, while the Standard and Poor’s 500 also finished at an all-time high. The Nasdaq rose 1.59% to 24,016.02 and the Standard and Poor’s 500 gained 0.80% to 7,022.95. (reuters.com, cnbc.com) The market case behind that move has centered on spending for the physical backbone of artificial intelligence: chip tools, data centers, servers and networking gear. On April 15, ASML said first-quarter earnings beat expectations and raised its 2026 revenue outlook to 36 billion euros to 40 billion euros as artificial intelligence lifted demand for its equipment. (reuters.com) ASML matters because it sells lithography machines, the tools chipmakers use to print circuits onto silicon wafers. The company is the only supplier of extreme ultraviolet lithography systems, the most advanced machines used to make leading-edge chips. (reuters.com) The same argument has shown up in hyperscaler budgets. Amazon said on February 5 that 2026 capital spending would jump more than 50% to about 200 billion dollars, with the build-out aimed at artificial-intelligence infrastructure, and the stock fell 11.5% after hours as investors weighed the cost. (reuters.com) Alphabet set an even bigger number. On February 4, the Google parent said 2026 capital expenditure would be 175 billion dollars to 185 billion dollars, up from 91.45 billion dollars in 2025, with servers, data centers and networking equipment at the center of the plan. (cnbc.com, reuters.com) Meta gave the same signal in January. The company said 2026 capital expenditure would be 115 billion dollars to 135 billion dollars, up from 72.22 billion dollars in 2025, tied to more computing capacity for its artificial-intelligence work and core business. (datacenterdynamics.com) That is why the recent rally has been framed less as excitement over chatbots and more as confidence that orders for chips and chip-making gear are still flowing. Reuters reported on April 15 that investors were returning to technology shares after weeks of war-related economic worries and concerns about artificial intelligence’s effects on jobs. (reuters.com) The caution is that this narrative still depends on the next proof point. Amazon’s February selloff after its 200 billion dollar spending plan showed that Wall Street will fund huge artificial-intelligence budgets only if earnings, cloud demand and orders keep justifying them. (reuters.com) For now, the rebound has a concrete shape: record Nasdaq levels, higher forecasts at ASML, and triple-digit billion-dollar budgets from Amazon, Alphabet and Meta. Investors have been buying the companies that build the picks, shovels and power lines of artificial intelligence. (reuters.com, reuters.com, cnbc.com)
