Apple Shares Plunge Nearly 10% as Supply Shortages Cloud Outlook Despite Strong iPhone Sales
Apple shares suffered one of their steepest single-day declines in years on Friday, July 31, 2026, falling nearly 10% after the company issued a weaker-than-expected revenue forecast that highlighted severe component shortages driven by the global artificial intelligence boom. The sell-off erased hundreds of billions of dollars in market value and raised the prospect that Nvidia could reclaim the title of the world’s most valuable company just days after Apple had briefly taken it back.
The stock closed at $308.91, down $24.52 or 7.35% from the previous session’s close of $333.43, after trading as low as $300 during the day. Early reports and intraday moves had put the decline closer to 9-10% at points, marking Apple’s worst performance since the sharp pandemic-related sell-off in March 2020 or the tariff-driven turbulence of 2025 in some measures. The drop wiped nearly $500 billion from Apple’s market capitalization.
The reaction came despite a strong set of results for Apple’s fiscal third quarter ended June 27, 2026. The company reported revenue of $109.4 billion, up 16% year over year and a record for the June quarter. Diluted earnings per share reached $2.02, up 29%, helped in part by a favorable impact from tariff-related refunds. iPhone revenue, Apple’s largest business, surged 22% to $54.3 billion, also a June-quarter record and ahead of Wall Street expectations. Mac sales were robust, supported in part by interest in the more affordable MacBook Neo, while services revenue hit $30.74 billion. The company noted that its installed base of active devices reached a new all-time high across major product categories and geographic segments.
Investors, however, focused almost entirely on the forward guidance. Apple projected revenue growth of only 9% to 11% for the current fiscal fourth quarter ending in September, below the roughly 12% that analysts had expected. The company indicated that iPhone growth would come in the mid-teens and that supply constraints would affect iPhones, Macs, and iPads. Softer growth in the high-margin services business added to the disappointment. Currency headwinds were also cited as a factor.
The root of the caution was an industry-wide squeeze on advanced processors and memory chips. The explosive build-out of AI data centers by major technology firms has soaked up manufacturing capacity and driven up prices for components that consumer electronics companies also need. Memory chip prices have risen sharply—by hundreds of percent in some periods—creating what outgoing CEO Tim Cook described as conditions resembling a “100-year flood.” Apple had previously drawn on stockpiled inventory to cushion the impact and had raised prices on certain Macs and iPads earlier in the year. Those buffers are now fading.
Cook, speaking on what he confirmed would be his final earnings call as chief executive, called the shortages “very significant” and said Apple had limited options to fully resolve them in the near term. He attributed much of the pressure not only to the broader AI demand surge but also to higher-than-expected demand for Apple’s own products, particularly the iPhone 17 lineup and Mac computers. In other words, strong customer interest was outstripping the company’s ability to secure enough chips. “The root cause of it is not a regular supply issue,” Cook noted in related commentary. “It’s a demand forecast issue, to be candid, where the iPhone and the Mac are both doing remarkably better than we thought they would do.”
The timing carries extra weight because of the leadership transition. Cook is stepping down as CEO on September 1, 2026, after 15 years in the role. He will become executive chairman of the board, while John Ternus, the longtime senior vice president of hardware engineering, will take over as chief executive. Cook used part of the call to endorse his successor, describing the transition as seamless and expressing strong confidence in Ternus and the broader team. “I am beyond excited for John to step into his new role and lead Apple into its next era,” Cook said. “He is truly one of a kind and there is no better person to take the helm of the company.” Ternus joined the call, signaling continuity on hardware and product execution.
The supply constraints come at a delicate moment for Apple’s hardware cycle. The next iPhone models are expected to launch in the September quarter that is now under pressure. Analysts have already been discussing potential price increases of $150 to $200 or more on higher-end models to offset rising component costs. Apple has historically managed to pass on some cost increases without collapsing demand, but the combination of higher prices and constrained availability could slow the upgrade cycle that investors have counted on. Services growth, which has been a key diversifier and margin driver, also faces questions if device sales slow or if regulatory changes in markets such as the European Union affect App Store economics.
Broader industry context underscores the challenge. The AI infrastructure race has redirected semiconductor capacity away from traditional consumer electronics toward data-center accelerators and high-bandwidth memory. This has led to longer lead times and higher costs across smartphones and PCs. Apple’s scale normally gives it preferential treatment in the supply chain, but even that leverage appears strained. One industry observer noted that if a company of Apple’s size is reporting lost flexibility, the situation is likely difficult for smaller players as well.
Analyst reactions were mixed. Several brokerages cut their price targets following the guidance, while a smaller number raised them. The median target moved to around $330, modestly below the pre-earnings closing level. Some analysts argued that the underlying demand for iPhones remains healthy and that Apple’s large installed base should continue to support services over time. Others expressed concern that AI has so far provided limited direct monetization tailwinds for Apple’s products and services, and that the company’s ability to navigate the component crunch will be closely watched in the coming quarters.
The episode also highlights the shifting competitive landscape. Nvidia has benefited enormously from the same AI boom that is constraining Apple’s supply. The market-value swing puts Nvidia in position to regain the top spot it had recently lost. For Apple, the longer-term questions center on how quickly it can expand its own semiconductor capacity arrangements, manage pricing without alienating customers, and accelerate AI features across its ecosystem in a way that drives both hardware upgrades and higher services engagement.
Despite the sharp stock reaction, Apple’s fundamentals in the just-reported quarter remained solid. Double-digit growth across major categories, record revenue and earnings for the period, and an expanding active device base provide a foundation. The company continues to generate substantial cash flow and returned capital to shareholders through dividends and buybacks. Yet the guidance miss and the clear acknowledgment of limited near-term supply flexibility have shifted investor focus from past performance to the risks ahead.
As Tim Cook prepares to hand over day-to-day leadership, Apple enters a new phase under Ternus at a moment when external constraints—rather than weak product demand—are the primary challenge. How the company navigates the memory and processor shortages, whether it can protect margins while meeting demand, and whether its AI investments begin to deliver clearer commercial returns will likely determine the trajectory of the stock in the months to come. For now, the market has delivered a clear verdict on the near-term outlook: caution is warranted even as the iPhone franchise continues to demonstrate underlying strength.
