The so-called Magnificent Seven—Microsoft, Nvidia, Alphabet, Apple, Meta, Tesla and Amazon—shed more than $2.3 trillion in market value in June, a 10 percent drop that marks the sharpest collective retreat since the AI rally began. Over the same period, the Philadelphia semiconductor index surged 93 percent year-to-date, its best run since 1999, while shares of memory and equipment suppliers such as Micron, Western Digital and ASML posted triple-digit gains. The divergence captures a fundamental realignment: investors are rotating out of the companies writing the cheques for AI infrastructure and into the firms cashing them.

Fund managers in New York and London describe a market that has tired of promises and is demanding tangible returns. Microsoft, Meta and Amazon are together committing close to a trillion dollars to data centres and AI models, yet the timeline for converting that spending into revenue remains opaque. By contrast, Taiwan’s TSMC has seen its market capitalisation exceed $2 trillion, and Dutch lithography leader ASML has gained 60 percent, as orders for advanced chips and fabrication equipment translate directly into earnings. The rotation has lifted Asian bourses: South Korean and Taiwanese indices have become global leaders, buoyed by chipmakers riding the AI buildout.

The shift coincides with an extraordinary boom in equity issuance, headlined by SpaceX’s historic Nasdaq debut. The IPO, priced at $135, drew the largest single-day retail net buying in Citadel Securities’ history and briefly pushed the company’s valuation above Amazon and Microsoft. Elon Musk’s net worth vaulted back above $1 trillion. The broader US market has already recorded $251 billion in IPOs and follow-on sales this year, eclipsing the full-year record set in 2021. Bankers at Goldman Sachs and Morgan Stanley point to a pipeline that includes a possible Anthropic offering and a $29 billion listing from South Korea’s SK Hynix, as AI infrastructure firms and private equity-backed companies rush to tap enthusiastic investors.

Yet the rotation has not halted AI investment; it has raised the bar for proof of profitability. Analysts at Wedbush and Fundstrat warn of a “gut check” moment, with the second-quarter earnings season in July set to test whether the hundreds of billions poured into AI are generating revenue growth. The Federal Reserve’s rate trajectory adds further uncertainty, as traders price in the possibility of hikes later in the year. The next factual milestone is the start of the tech earnings season, when the Magnificent Seven must demonstrate that their AI wagers are beginning to pay off.
