It's important to note that this isn't the first time Nvidia has claimed the title of the world's most valuable company. In fact, just a few months ago, in January, Nvidia's market value surpassed those of Microsoft and smartphone giant Apple.

Nvidia reclaims top spot as the most valuable publicly traded company with a $3.45 trillion market cap, surpassing Microsoft.

Nvidia has overtaken Microsoft as the largest U.S. company by market value, regaining the throne that it forfeited during the AI-stock selloff in late January. Nvidia shares rose 2.9% during Tuesday’s trading.
