Apple has lost its position as the world's most valuable public company to Microsoft following a dramatic four-day slide in its stock price, driven largely by concerns over President Donald Trump's escalating tariff war with China, where most of its iPhones are assembled.
Apple's market capitalization fell to $2.59 trillion as of Tuesday's close, while Microsoft now sits at $2.64 trillion, reclaiming the top spot after briefly holding it earlier this year.
Apple shares have plummeted approximately 23% over just four trading sessions, shaving $700 billion off its value, as panicked investors dump stock due to the company's exposure to China for manufacturing and sales. Apple relies heavily on Chinese manufacturing for its flagship products, making it especially vulnerable to Trump's aggressive tariff policies.
The broader market has been shaken by Trump's announcement of substantial tariffs on imports from more than 100 countries, with the Nasdaq dropping 13% over the same four-day period. However, Apple's decline has outpaced other tech companies due to its particular vulnerability to U.S.-China trade tensions.
UBS analysts have predicted that the price of the iPhone 16 Pro Max could increase by as much as $350 in the United States as a result of the tariffs. The potential price hike raises questions about how consumers might respond to significantly more expensive Apple products.
Apple has been exploring manufacturing diversification in countries like India and Vietnam in recent years, but analysts suggest it would be nearly impossible for the company to quickly shift its complex supply chain away from China. That's despite President Trump saying he "absolutely" believes that Apple could manufacture its iPhones and other devices in the United States. Apple CEO Tim Cook has previously said that China's manufacturing expertise and scale are unmatched globally.
Both Apple and Microsoft, along with chipmaker Nvidia, had recently achieved market valuations exceeding $3 trillion before the current market turbulence began.
Microsoft appears somewhat insulated from the worst effects of the tariffs, with Jefferies analysts recently including the company among those they view as better positioned to weather the current uncertainty.
The two tech giants have traded the "most valuable company" title several times in recent years, with Microsoft claiming the top spot in early 2024 before Apple regained it – only to lose it again during this week's market volatility.
According to one report, Apple earlier this week urgently requested suppliers to ship as many premium devices as possible to the U.S. by air freight before Trump's falsely-described "reciprocal" tariffs of 104% on China came into effect Wednesday. China has since retaliated by slapping 84% tariffs on U.S. goods.
