Apple has suffered its worst one-day decline in over a year, after increasing prices across multiple product lines on Thursday.

Today, the company made its first move in response to the memory cost crisis due to the demand from AI servers and data centres.

The stock market has had a negative reaction to the news, as Apple is down 6.15% today, wiping roughly $260bn from its market cap.

This is the biggest single day decrease since April 2025, according to CNBC.

Apple says that it has "never seen a component price increase this much, this quickly" and claims that they have prevented passing increased costs onto their customers, but have "reached a point where we need to begin raising prices on a number of products", according to Mark Gurman.
