Apple Overtakes Nvidia as the Most Valuable US Company After Nvidia Loses 250 Billion Dollars in a Session
Apple moved ahead of Nvidia as the most valuable US company on Monday, 27 July 2026, after a sharp divergence between the two stocks produced a one-day swing of more than 300 billion dollars in their relative value, our calculation. Nvidia lost about 250 billion dollars in market value while Apple added about 57 billion, per CNBC and our calculation.
Nvidia shares fell 4.99 percent to 196.51 dollars, trimming its estimated market capitalisation to about 4.76 trillion dollars, while Apple rose 1.17 percent to 336.91 dollars, touching a fresh 52-week high during the session and lifting its estimated value to about 4.95 trillion. Apple finished the day about 192.8 billion dollars ahead of Nvidia, our calculation.
The reversal was larger than Nvidia’s 250 billion dollar loss alone. At the previous close Nvidia had led, valued at about 5.01 trillion dollars against about 4.89 trillion for Apple, a lead of roughly 114.3 billion dollars, our calculation. By Monday’s close that advantage had become an Apple lead of about 192.8 billion dollars, a one-day swing in relative value of about 307.1 billion dollars, our calculation.
The market-value figures are estimates based on Monday’s closing prices and each company’s latest publicly disclosed share counts, about 14.687 billion shares for Apple and 24.2 billion for Nvidia. Estimates can differ slightly among data providers because companies continue to issue and repurchase shares between disclosures, our reading.
Why it matters: The crossover is a clear read on shifting investor preference at the very top of the market, our reading. Nvidia’s valuation rests on the capital-intensive infrastructure behind the artificial-intelligence build-out, while Apple’s leans more on its consumer-device ecosystem, services and cash generation. A swing of this size in a single day also shows how concentrated the market has become at the top, where a handful of names now drive much of the index return and a few percentage points of relative performance can reverse the ranking, our reading. Apple’s lead is only about 4 percent of Nvidia’s value, so the order could change again on a modest move, our reading.
Outlook: Apple’s upcoming quarterly results are the next test of whether its earnings, margins, device demand and artificial-intelligence strategy support a valuation approaching 5 trillion dollars. For Nvidia, the focus stays on the durability of demand for its processors and the returns from global data-centre investment. The near-term ranking may stay volatile, and the open question is whether Apple’s move to the top proves lasting or a temporary interruption to Nvidia’s run, our reading.
