Apple and Microsoft Reach $4 Trillion Market Cap

On Tuesday, both Apple and Microsoft joined Nvidia in the exclusive $4 trillion market cap club, marking a significant rise in their stock values. This development elevates these companies, placing them alongside other prominent tech giants.

Nvidia, which achieved this milestone back in July, still leads the three companies with a market capitalization close to $4.8 trillion.

Apple’s Performance

Apple’s stock hit a peak during the day but ultimately closed slightly lower at $269 per share. It seems the excitement surrounding the new iPhone 17, launched in mid-September, has played a significant role in propelling its stock price.

Wedbush Securities’ analyst Dan Ives believes there’s still a lot of untapped potential for Apple, suggesting that many investors have not fully appreciated the impact of the iPhone 17 cycle. In a note to investors, he noted, “We think the public is still underestimating the iPhone 17 cycle we’re currently witnessing, with an estimated 315 million of the 1.5 billion iPhones out there having gone four years without an upgrade.”

Apple is also establishing a new factory in Texas.

Recently, Apple CEO Tim Cook was seen alongside President Donald Trump and Treasury Secretary Scott Bessent during a high-profile visit to Japan.

Despite reaching the $4 trillion mark, Apple has only seen about a 7% increase in shares this year, falling short compared to the Nasdaq Composite, which has risen 23%. Ives expressed curiosity about Apple’s lesser-known “invisible AI strategy.” Apple plans to announce its quarterly results after the market closes on Thursday.

Microsoft’s Rise

On the same day, Microsoft’s stock climbed back to the $4 trillion level, closing at $542.07 per share, coinciding with its recent deal with OpenAI, which has now restructured into a public benefit corporation valued at around $500 billion.

This growth has fueled a nearly 30% increase in Microsoft’s shares this year, with earnings to be reported after trading wraps up on Wednesday.

The AI Landscape

The combined worth of Apple and Microsoft now stands at $4 trillion, which is larger than the GDP of almost every country except the U.S., China, Germany, and Japan, according to data tracked by Dow Jones Market Data Group.

These impressive gains for Apple and Microsoft are contributing to record highs across major U.S. stock averages, including the Dow, S&P 500, and Nasdaq Composite.
