On January 28, Reuters reported that short sellers of artificial intelligence-related stocks reaped significant profits following the successful launch of cost-effective AI models by China's DeepSeek. With their bets against Nvidia, short sellers accumulated record profits exceeding $6 billion.

Traders who bet against Nvidia, a prominent player in AI, earned around $6.6 billion in profits, marking the largest single-day gain ever recorded for the stock, as reported by data analytics firm Ortex.

Nvidia experienced a staggering $593 billion decline in market value on Monday, representing the largest single-session loss for any company. This decline came after a Chinese startup introduced AI models comparable to or better than leading U.S. models, but at a fraction of the cost.

Short sellers of chipmaker Broadcom also saw profits surpassing $2 billion.

Additionally, other AI-related stocks like server-maker Super Micro, data-center operator Equinix, and energy provider Vistra faced substantial losses on Monday, generating a collective profit exceeding $900 million for investors who bet against these companies, according to Ortex.
