Apple's Foldable iPhone Boosts Market Cap by Hundreds of Billions

Apple's market capitalization surged to nearly $4.77 trillion after the unveiling of its first foldable iPhone, dubbed the 'iPhone Duo'. The stock jumped 3.56% on September 10, 2026, from $315.34 to $326.57, pushing Apple's market value into the hundreds of billions.

The move is significant because it represents a premium reset for the company, with investors betting that the foldable iPhone will drive revenue growth and boost average selling prices.

However, analysts caution that the one-day pop may be overstating the case, as Apple's stock price can retreat quickly. The seven-day sentiment change of -10.95 in the composite reading suggests some enthusiasm was already cooling before the launch.

The bull case for Apple relies on the Duo pulling the top of its premium ladder higher while iPhone, Mac, and Services continue to grow. With a strong operating baseline, including $109.42 billion in revenue growth in Q3 2026, analysts are optimistic about Apple's prospects.
