Apple's week on Wall Street was a study in extremes. The iPhone maker briefly became the first company after Nvidia to cross the $5 trillion market capitalization threshold, only to suffer its steepest single-day decline since the 2020 pandemic crash after a cautious earnings outlook. The whipsaw underscores how even companies that have deliberately avoided the AI capital spending arms race are now being caught in its undertow.
For much of 2025, investors treated Apple as a defensive play amid fears that hyperscalers like Microsoft, Amazon, Alphabet, and Meta were pouring hundreds of billions into AI infrastructure with uncertain returns. Apple's strategy of leaning on partners such as Google for AI features allowed it to sidestep the heavy capital expenditures weighing on its peers, and its shares outperformed much of Big Tech as a result.
That narrative unraveled on Friday. Apple's stock tumbled nearly 10% after management guided for September-quarter revenue growth of 9% to 11%, below the roughly 12% analysts had expected. The company also flagged persistent component shortages and cost pressures that would compress gross margins to 47%–48%, down from about 50% in the June quarter. The selloff threatened to erase nearly $500 billion in market value, handing the title of the world's most valuable company back to Nvidia.
From safe haven to earnings loser
The week began with Apple reclaiming the top spot from Nvidia on Monday, as Nvidia's shares dropped 5% on concerns about AI spending returns. Apple's market cap rose to $4.95 trillion, then briefly crossed $5 trillion on Tuesday. But the earnings report on Thursday revealed cracks beneath the surface.
Revenue for the fiscal third quarter ended June 27 rose 16.4% to $109.42 billion, beating expectations, and adjusted earnings of $2.02 per share (including 11 cents from US tariff refunds) also topped forecasts. iPhone sales surged 21.7% to $54.25 billion, the strongest third-quarter performance in the company's history. Yet investors focused on the services segment, which grew 12.1% to $30.74 billion—below the $31.22 billion consensus. DA Davidson analyst Gil Luria noted that a deceleration in services, Apple's highest-margin business, could signal trouble ahead as iPhone growth normalizes.
Supply chain constraints take center stage
CEO Tim Cook acknowledged that supply-chain flexibility has largely evaporated, citing "very significant constraints" with limited ability to remedy them. The comments surprised investors who had long viewed Cook as a master of supply chain management. The shortages, tied to AI-driven demand for advanced chips and other components, are now a primary headwind for Apple's near-term profitability.
The broader AI trade has also been volatile. Nvidia's valuation has swung wildly as investors debate whether hyperscaler spending will generate adequate returns. Apple's brief $5 trillion milestone was seen as a rotation into a "steady-eddy" name, but Friday's plunge shows that no large-cap tech is immune to the AI ripple effects. As AI cloud earnings continue to dominate headlines, Apple's reliance on partners may no longer shield it from the sector's turbulence.
Apple's guidance also highlighted a slowdown in Greater China, a key market, and the impact of tariff refunds that are set to diminish. The company's services growth, while still robust, is decelerating from prior quarters, raising questions about its long-term margin trajectory. Investors are now weighing whether Apple can navigate the AI-driven supply chain crunch without sacrificing its premium positioning.
As the market digests this week's events, Apple's status as an AI haven has been called into question. The company's ability to manage component shortages and sustain services growth will be critical in the coming quarters. For now, the stock's sharp reversal serves as a reminder that even the most defensive megacaps are not insulated from the AI boom's collateral damage.
