NVIDIA is nearing a $6 trillion market capitalization, which would make it the first company ever to reach that level. The chipmaker's shares closed at a record high, leaving its valuation just shy of the milestone. Its position reflects its dominance in artificial intelligence and investor confidence in its growth.

The push toward $6 trillion is supported by a robust revenue outlook, a recently announced massive share buyback program, and sustained high demand for NVIDIA's AI chips. Options markets price a roughly 50% chance that NVIDIA will reach the milestone by the end of October.
