Google parent company Alphabet’s market value crossed $3 trillion for the first time on Monday as strong gains in its shares reflected renewed optimism over artificial intelligence and a favourable antitrust ruling, Reuters reported.Class A shares surged 4.6% to $251.88 while Class C climbed 4.5% to $252.30, both scaling record highs. Alphabet now joins Apple and Microsoft in the $3 trillion club, while Nvidia has surged even higher with a $4 trillion valuation.The latest lift came after a US federal judge allowed Alphabet to retain control of its Chrome browser and Android operating system — a pivotal ruling for the tech giant, whose dominance in search and mobile ecosystems has faced sustained scrutiny.Investor sentiment was further buoyed by a 32% year-on-year jump in Alphabet’s cloud revenue in the second quarter, outpacing estimates. Gains were underpinned by investments in custom chips and its Gemini AI model.
