Alphabet overtakes Apple at $4.51 trillion as AI race reshuffles rankings

Alphabet overtook Apple to become the world's second-most-valuable company, with Google's Class A shares climbing 3.5 percent to lift its market capitalization to $4.51 trillion.

Apple Chief Financial Officer Kevan Parekh said supply constraints on memory, processors and other components would hit iPhone, Mac and iPad sales in the fourth quarter, while currency swings would also dampen revenue growth.

Apple shares fell 0.7 percent, trimming its market value to $4.48 trillion, while Nvidia slipped 1.03 percent to $4.81 trillion, keeping the AI chipmaker atop the global rankings.

The reshuffling shows the center of gravity in tech valuations has shifted from consumer electronics to AI chips and cloud computing, with Alphabet's cloud and robotics momentum now challenging Nvidia's lead.

Gemini Robotics 2 Fuels Alphabet's Rally

Alphabet's surge followed Google DeepMind's unveiling of Gemini Robotics 2, a model that uses a single system to control a humanoid robot's full-body movements, including walking, crouching and bimanual object manipulation, while autonomously planning multi-step tasks. The company disclosed future data center-related committed spending of up to $811 billion, a bet on AI and cloud businesses that investors rewarded despite broader concerns over hyperscaler capital expenditure. Alphabet derives nearly 90 percent of its revenue from Google services, primarily advertising, with the balance from subscriptions, cloud computing and emerging businesses such as self-driving cars.

Apple's Guidance Misses as Supply Constraints Bite

Apple guided fourth-quarter fiscal 2026 revenue growth of 9 percent to 11 percent, below the 12.1 percent analysts expected. The company's shares had already fallen 7.35 percent on July 31 — the steepest single-day drop since March 2020 — after the earnings report, erasing about $359 billion in market value. Apple's capital expenditure of roughly $11 billion over the past 12 months trails Microsoft, Alphabet and Amazon, which each invest about $200 billion annually in AI infrastructure. Unlike Amazon and Microsoft, which have shown through their cloud businesses that AI investment can translate into revenue, Apple lacks a large-scale cloud revenue stream and has become a victim of memory shortages caused by AI infrastructure competition.

Valuation and Positioning

Apple trades at a price-to-earnings ratio of roughly 39 times, higher than faster-growing cloud giants at about 16 to 26 times, leaving valuation pressure without new growth drivers. Alphabet, by contrast, carries a P/E of 18.77, below its five-year median of 24.2, though GuruFocus data shows GOOGL trading 51.2 percent above its GF Value of $247.22. Fifty-six gurus hold GOOGL shares, with 16 adding and 34 trimming positions, while insiders sold $4.4 million worth of stock over the past three months with no buying.

The ranking shift carries implications for index weightings and fund flows, as Alphabet's rise strengthens its position in the S&P 500 while Apple's slide trims its influence. Whether Alphabet can close the roughly $300 billion gap to Nvidia will hinge on its ability to convert AI infrastructure spending into revenue, a test that will play out in coming quarters.
