Super Micro’s $50 billion stock collapse underscores risk of AI hype

In March, Super Micro Computer was added to the S&P 500 after an epic run that lifted the stock by more than 2,000% in two years, dwarfing even Nvidia’s gains.

As it turned out, S&P was calling the top.

Less than two weeks after the index changes were announced, Super Micro reached its closing high of $118.81 and had a market cap of almost $70 billion. The stock is down 72% since then, pushing the valuation to under $20 billion, the first major sign in the public markets that the hype around artificial intelligence may not all be justified.

Super Micro is one of the primary vendors for building out Nvidia-based clusters of servers for training and deploying AI models.
