Apple has moved back ahead of Nvidia in the battle to become the world’s most valuable public company, according to the latest update on their changing market capitalizations. The ranking has flipped again after a recent stretch in which the two tech giants traded places.

The latest move puts Apple back on top while the company continues to push toward a $5 trillion valuation. The update notes that Apple has not officially crossed that milestone yet, although intraday trading reportedly brought it close.

The renewed lead highlights how tight the Apple vs Nvidia valuation race has become. With both companies carrying enormous market values, even relatively small swings in their share prices can be enough to change which one holds the No. 1 position.

For investors and market watchers, the bigger story is not just that Apple overtook Nvidia again, but that Apple is now being discussed in the context of a possible $5 trillion market cap. That keeps attention firmly on both $AAPL and $NVDA as the competition at the top of the market remains unusually close.
