Microsoft loses $400 billion in few hours, what’s behind one of the worst stock market days for the company

Microsoft dragged down the benchmark with an 12% slide, which would be its worst day since March 2020. The company saw more than $400 billion wipeout in stock market valuation, which is the second-largest in history. Shares of the software giant were down 12% as of 1:20 p.m., their biggest intraday plunge since March 2020, erasing roughly $424 billion in market value. The only larger one-day valuation destruction in stock market history was Nvidia’s $593 billion rout in January last year after the launch of DeepSeek’s low-cost AI model.

According to Bloomberg, the roughly 12% drop in Microsoft’s share price is among the worst in its history.
