Alphabet hit $3 trillion market cap, fueled by AI gains and a favorable antitrust ruling.

Alphabet, parent company of Google, reached a $3 trillion market capitalization for the first time on Monday, becoming the fourth company globally to achieve this milestone. The surge was driven by a 3.8% rise in Class A shares to $250 and a 3.7% increase in Class C shares to $250.4, both hitting record highs. Investor confidence was boosted by a favorable antitrust ruling and strong momentum in artificial intelligence, particularly through Google's AI initiatives and cloud services. The company's shares have risen over 32% this year, outperforming other major tech firms.
