Oklo, Vistra, Constellation Energy Stocks Sink As China’s DeepSeek AI Launch Sparks Concerns: Retail Investors Spooked

Shares of several energy stocks, including OpenAI co-founder Sam Altman-backed Oklo Inc. (OKLO), Constellation Energy Corp. (CEG), and Vistra Corp. (VST), among others, plunged in mid-day trade on Monday.

Oklo’s stock price plunged almost 29%, Vistra’s share price was down 28%, and Constellation Energy’s share price declined almost 20% at the time of writing.

This comes amid a broader selloff across the technology sector, especially in the semiconductor industry, with Nvidia Corp. (NVDA) tumbling over 15%.
