As attention on Chinese startup DeepSeek and its artificial-intelligence model led to a $1 trillion wipeout in the U.S. stock market on Monday, shares of bitcoin miners with exposure to artificial intelligence also tumbled.

Bernstein remains bullish on Core Scientific (CORZ) even after the shares tumbled 30% earlier this week as Chinese artificial intelligence (AI) startup DeepSeek challenged the idea that bitcoin (BTC) miners had value as data center plays. The slide means the stock is now available at a deep discount, the broker said in a research report Thursday.

Bitcoin miner Riot Platforms (RIOT) finds itself a target of a second activist investor, with Reuters reporting investment management giant D.E. Shaw as having taken an unspecified stake.

Investment firm D.E. Shaw has built a position in Riot Platforms and may push it to make changes, two sources familiar with the matter said, making it the second activist shareholder to do so at the cryptocurrency mining company.
