Sept. 15 (UPI) -- Shares of Google's parent company Alphabet soared on Monday, pushing the tech conglomerate's market capitalization past the $3 trillion mark for the first time.

The development puts the search engine giant among a handful of other tech companies that have reached the milestone, which include Apple and Microsoft, as well as AI chipmaker Nvidia. Shares of Alphabet were up by more than 4% and were hovering at around $250 as of Monday afternoon.

The company's all-time high follows its precipitous stock rise that began in early September when a federal judge ruled that Google would not have to sell off its Chrome browser or Android operating system. The ruling by Judge Amit Mehta was in response to antitrust lawsuit brought by the Justice Department accusing the company of running illegal search engine monopoly.

The ruling meant that Google dodged some of the most consequential remedies sought by federal prosecutors and Mehta still ordered the company to share some search engine data with rivals. The order also barred Google from contracts with other companies making its search engine and other products the default options on their products.

Stock market analysts anticipated the asendance of Alphabet's stock following the ruling, and the company's gains Monday account for nearly a third of its value this year, reported Investopedia.

The milestone for Google comes nearly two decades after the company's first IPO when it began selling publicly traded stocks.
