Google's parent company surpasses $3 trillion for the first time

Alphabet's share price rose nearly 4 percent to $250.7.

With the rise in its shares, Alphabet's market value reached $3.03 trillion.

Thus, Alphabet ranked 4th among the world's most valuable companies, after Nvidia, Microsoft and Apple.

Alphabet's shares gained momentum in early September after a U.S. federal court ruled that the company was not required to sell its Chrome browser as part of an antitrust case against Google.
