Investors were looking to Microsoft and Meta to provide reassurance that they will keep spending heavily on Nvidia chips.

Nvidia stock jumped in Europe on Wednesday, suggesting shares in the company at the heart of the artificial intelligence markets boom may recover further after a steep drop this week triggered by the rise of China's DeepSeek AI tool.

Retail investors bought a net $562 million of Nvidia stock on Monday, the largest single-day inflow in at least 10 years, VandaTrack said.

DeepSeek stunned the tech world with the release of its R1 "reasoning" model, matching or exceeding OpenAI's reasoning model for a fraction of the cost.

Nvidia’s AI leadership remains intact, despite DeepSeek concerns. Read why NVDA stock’s steep drop represents a great opportunity for long-term investors.

Chinese startup DeepSeek has achieved what many (including experts) thought impossible: create a foundational, competitive AI model for just $5.6 million. By comparison, OpenAI’s unreleased GPT-5 (codenamed “Orion”) reportedly requires $500 million for six months of training.

What just happened to Nvidia — and the S&P 500 as a whole, really — embodies so much of the uncertainty surrounding the global AI war. But where Big Tech may be failing, opportunities are opening up for competitors and investors alike.
