Lead
Apple briefly became the world's most valuable publicly traded company on Friday, Oct. 23, 2026. Its shares rose above $351 and its market value reached roughly $5.1 trillion, ahead of Nvidia. The move came on the day the iPhone Duo, the company's first foldable iPhone, reached stores. Nvidia took the top spot back by the close of trading, as a three-week slide in ai stocks left the chipmaker down nearly 12% from early October.What Happened on Launch Day?
Apple overtook Nvidia during Friday's session and held the lead intraday before losing it at the close. Apple shares touched $351.73, a record high. They finished down 0.14% at $347.73, for a market value of $5.074 trillion.
Nvidia fell 0.59% to $210.96, for a market value of $5.094 trillion. That left it about $20 billion ahead of Apple. The two companies have traded the top ranking several times this year, and the gap between them on Friday was under 0.5% of either company's value.
Why Did Nvidia Slide About 12%?
Nvidia's decline reflects a broad pullback in artificial intelligence names tied to concern over the scale of AI spending. Nvidia fell 4.4% on Thursday, Oct. 22. The Nasdaq Composite dropped 2.6% that day, and Meta Platforms (META) lost 7% as investors reassessed how quickly heavy data-center outlays will translate into revenue. The sell-off in nasdaq meta shares added to pressure on the suppliers of AI hardware.
Measured from the Oct. 6 close through Oct. 23, Nvidia was down about 11.8%. Apple rose about 4.2% over the same stretch. Over the past 20 trading sessions, Apple has gained roughly 4.4% and Nvidia has fallen about 6%, so the recent drop is steeper than the one-month trend.
Why Does the iPhone Duo Matter for Apple's Valuation?
The iPhone Duo matters because it is Apple's first foldable handset and the first major new form factor for the iPhone in years. Strong early demand at launch supported the rally to a record high. The device targets the premium end of the smartphone market, where higher selling prices lift revenue per user and gross margin across Apple's installed base.
Apple's gains also carry a defensive element. Its earnings depend less on data-center capital spending than Nvidia's do, so investors shifted toward it as AI-related concerns grew. A hardware launch with a visible sales catalyst gave that rotation a concrete trigger.
Market Reaction
The two stocks are the largest weightings in major U.S. equity benchmarks, so their relative moves affect index performance. Friday's session showed the market leadership gap narrowing. Nvidia remains the larger company by a thin margin, but the ranking now turns on daily moves of less than 1%.
Outlook
Apple's brief lead shows how narrow the margin at the top of the market has become. Nvidia's position depends on whether AI spending concerns ease. Apple's depends on whether iPhone Duo demand holds beyond launch week. With the two separated by about $20 billion on a combined value above $10 trillion, further changes at the top are likely in the near term.
