NVIDIA closes in on $6 trillion market cap as stock hits all-time high

NVIDIA stock set a new all-time high, with an intraday peak of $242 that left the company's market capitalization near $5.7 trillion. CNBC's analysis of options pricing shows traders assign roughly a 50% chance that NVIDIA crosses $6 trillion by October 31, rising to 67% by December 18.

The drivers are visible across this week's headlines. SpaceX is reportedly raising $40 billion to buy NVIDIA chips. Mistral trained its 1T-parameter Large 4 on Grace Blackwell GPUs. Reflection AI's Beam is pitched as cheap to run on NVIDIA hardware. Samsung's forecast record profit reflects HBM demand driven largely by NVIDIA accelerators. On the software side, NVIDIA shipped AICR v1.0 for verifiable GPU-cluster configuration and published work on Green Contexts for GPU sharing, deepening the platform lock-in that justifies its premium.

The main risk is China. Bloomberg Intelligence says DeepSeek has narrowed the US-China model gap to about 3%, and Bloomberg Opinion argues DeepSeek and Huawei are going after NVIDIA's moat inside China. The January 2025 DeepSeek R1 shock wiped out $589 billion of NVIDIA's value in one day, though the stock recovered quickly.

Other caveats include data-center moratoriums slowing US buildouts, as AWS warned this week, and the growing role of debt in GPU purchases. Watch upcoming earnings guidance and whether hyperscaler capex commentary keeps accelerating.
