Big Tech’s $4 Trillion Moment: Apple Joins Microsoft, Nvidia In The Elite Club

• While Microsoft’s market capitalization had crossed the $4 trillion level in July, this is the first time Apple has crossed the milestone.
• Microsoft’s stock jumped on the renewal and expansion of its deal with OpenAI, while Apple’s shares are up on optimism around its iPhone 17 series.

Apple Inc. (AAPL) and Microsoft Corp. (MSFT) shares gained in Tuesday’s opening trade, sending the market capitalization of both companies above the $4 trillion level.

While Microsoft’s market capitalization had crossed the $4 trillion level in July, this is the first time Apple has crossed the milestone. Microsoft’s shares were up nearly 3% in Tuesday’s opening trade, while Apple’s shares were up 0.3% at the time of writing.

Apple’s market capitalization stood at $4.006 trillion at the time of writing, while Microsoft’s stood at $4.06 trillion. Nvidia remains at the top, with a market capitalization of $4.72 trillion.

Microsoft’s stock jumped on the renewal and expansion of its deal with OpenAI, giving the company an approximately 27% stake valued at nearly $135 billion in the AI startup. Apple’s shares are up on optimism around its iPhone 17 series.

Microsoft’s OpenAI Deal

Apart from a stake in OpenAI, the renewed partnership also stated that Microsoft retains exclusive intellectual property (IP) rights until artificial general intelligence (AGI) is reached. OpenAI will also purchase an additional $250 billion in Azure services under the agreement.

Microsoft also has the freedom to pursue AGI independently, either alone or in partnership with others.

Apple’s iPhone 17 Momentum

According to data from market research firm Counterpoint, the iPhone 17 series has outsold the iPhone 16 in the first 10 days of its availability in Apple’s key markets, the U.S. and China.

“The base model iPhone 17 is very compelling to consumers, offering great value for money. A better chip, improved display, higher base storage, selfie camera upgrade – all for the same price as last year’s iPhone 16,” said Mengmeng Zhang, Senior Analyst at Counterpoint Research.

According to TheFly, analysts at JPMorgan on Monday expressed optimism about Apple’s performance in the fourth quarter (Q4) of fiscal 2025 and the first quarter (Q1) of fiscal 2026.

The firm expects robust high-single-digit revenue in both quarters, adding that this should reinforce a positive product cycle for Apple among its investors. JPMorgan hiked its price target on Apple stock to $290 from $280, while maintaining its ‘Overweight’ rating.

AAPL stock is up 8% year-to-date, while MSFT stock is up 30%.
