Google Antitrust Win Sparks $420 Billion Surge as Tech Giants Hit $21 Trillion Market Value

The U.S. tech industry capped off a historic week, with megacap stocks adding more than $420 billion in market value, pushing their combined worth to an unprecedented $21 trillion. The surge was fueled by Alphabet’s courtroom victory in the remedies phase of its antitrust battle, a rally that lifted Apple alongside it, while Broadcom secured a massive $10 billion AI contract. Despite Nvidia and Microsoft seeing declines, the week ended as one of the strongest for Big Tech in 2025.

Alphabet shares soared over 10% for the week, buoyed by U.S. District Judge Amit Mehta’s decision not to force Google to sell its Chrome browser. Instead, the company faces lighter remedies, including sharing search data with competitors. The ruling was also a relief for Apple, which can maintain its lucrative deal with Google to remain the iPhone’s default search engine. Analysts said the decision clears the path for deeper AI collaboration between Apple and Google, particularly around Gemini, Google’s flagship AI model.

Broadcom was another major winner, climbing 13% after CEO Hock Tan revealed a new $10 billion deal with a large AI customer, widely speculated to be OpenAI. The chipmaker has now officially joined the trillion-dollar club, with its market value surging to around $1.6 trillion. Analysts praised Broadcom’s strong AI-driven growth and noted its expanding role as a key supplier to tech giants including Google, Meta, and ByteDance.

Not all tech leaders had a winning week. Nvidia shares dropped 4%, extending a month-long slide despite no negative company-specific news. Microsoft also slipped, marking its fifth consecutive weekly decline. Still, Nvidia remains the world’s most valuable company, worth more than $4 trillion, while Microsoft’s stock is up over 20% in the past year, underscoring the sector’s resilience despite short-term volatility.

Meanwhile, Tesla regained some momentum, rising 5% after announcing a bold new pay package for CEO Elon Musk that could be worth nearly $1 trillion if the EV maker hits ambitious growth targets. The company, struggling with competition from China and slowing sales, hopes the plan will keep Musk committed to Tesla’s long-term future. Chairwoman Robyn Denholm said the incentive is designed to keep Musk “motivated and focused on delivering for the company.”
