Retail investors bought a record amount of Nvidia stock on Monday after concerns over a low-cost artificial intelligence model from Chinese startup DeepSeek stripped 17% off its shares, or $593 billion from its market value.

One of the biggest beneficiaries of this trend is Nvidia (NASDAQ: NVDA), which pioneered the graphics processing units (GPUs) that have become the gold standard for running AI systems. However, reports emerged recently that suggested a Chinese start-up had cracked the code for developing strong AI systems while using inferior chips and novel training processes.

Everyday traders bought more than $562 million worth of Nvidia shares on balance Monday, according to data from Vanda Research that subtracts total outflows from inflows. That marked a record for daily net inflows into Nvidia as mom-and-pop investors bucked their institutional counterparts, who dumped the stock en masse.
