Apple shares fell nearly 10% in after-hours trading after the company issued fourth-quarter revenue guidance below Wall Street's expectations, despite beating estimates for its fiscal third quarter. The miss threatens to erase roughly $500 billion in market value and could let Nvidia reclaim the title of world's most valuable company.
Apple shares fell nearly 10% in after-hours trading on July 31, threatening to erase roughly $500 billion in market capitalization — even after the company beat estimates on both revenue and earnings per share for its fiscal third quarter.
The trigger: Apple's fourth-quarter revenue growth forecast of 9% to 11% landed below Wall Street's consensus estimate of approximately 12%. In a market that punishes anything short of perfection, a solid quarter wasn't enough to offset cautious guidance.
Strong quarter, weak outlook
Apple's fiscal Q3 2026 results, reported on July 30, beat analyst expectations on revenue and earnings per share, with iPhone sales driving the outperformance. But guidance carried the weight this time.
CEO Tim Cook pointed to an "increasing impact" from memory shortages as a constraint on near-term performance. AI data centers are pulling memory chips from the supply chain at a pace that's squeezing availability for other manufacturers, including Apple.
The gap between Apple's projected growth and the Street's expectation looks narrow on paper. Yet with a pre-drop market cap around $4.89 trillion, even a slight miss can wipe out hundreds of billions in value overnight.
Nvidia waits in the wings
A $500 billion drop would let Nvidia reclaim the title of world's most valuable company, a position the two firms have traded as the AI narrative reshapes the tech sector. Apple's decline stems partly from memory shortages tied to AI demand, while Nvidia benefits as the leading supplier of the GPUs driving that same demand.
Supply chain strain reaches beyond Apple
The memory shortage is not unique to Apple. AI infrastructure buildouts are straining the broader semiconductor supply chain, a structural imbalance that could raise hardware costs and reshape capital spending plans across the tech sector.
