Alphabet, the parent company of Google, has joined the exclusive ranks of the world’s most valuable corporations after its market valuation crossed $3 trillion on Monday. The milestone, driven by investor enthusiasm for artificial intelligence and a favourable US court ruling, makes Alphabet only the fourth company in history to hit the mark, alongside Nvidia, Microsoft, and Apple.
Shares in the California-based tech giant climbed more than 4 percent in trading, closing at $251.61 and pushing its market capitalisation to $3.04 trillion. The stock has surged 31 percent since the start of the year, buoyed by robust earnings, rapid adoption of AI services, and renewed investor confidence following a landmark antitrust reprieve earlier this month.
The latest rally comes on the heels of a September decision in Washington that eased fears Alphabet could face a forced break-up. A judge rejected calls from the US Department of Justice to compel Google to divest its Chrome browser and Android mobile operating system. The ruling followed a 2023 finding that Google had maintained an illegal monopoly in search. Shares jumped to record highs after the decision, with President Donald Trump personally congratulating Alphabet chief executive Sundar Pichai during a White House dinner.
Alphabet continues to face scrutiny abroad. Earlier this month, European Union regulators imposed a fine of nearly €3 billion for anti-competitive practices in advertising technology. Yet despite regulatory pressures, the company has outperformed expectations in 2025.
Second-quarter results highlighted broad-based growth, with revenues reaching $96 billion. Google’s core search business posted a 12 percent rise to $54.2 billion, while YouTube advertising also beat forecasts. Google Cloud revenues surged nearly a third to $13.6 billion, underscoring Alphabet’s dominance across multiple digital sectors.
Artificial intelligence remains central to the company’s momentum. Pichai said in July that Google’s AI-powered “overviews” feature is now used by 1.5 billion people worldwide. Meanwhile, its multimodal AI assistant Gemini continues to expand into new markets and services. “We are leading at the frontier of AI and shipping at an incredible pace,” Pichai told investors. “AI is positively impacting every part of the business, driving strong momentum.”
The stock’s rise also reflected broader optimism across Wall Street ahead of this week’s Federal Reserve policy meeting, where a widely expected quarter-point interest rate cut is set to be confirmed.
Alphabet’s achievement puts it in rarefied territory. Nvidia recently became the first company to reach a $4 trillion valuation, overtaking Microsoft and Apple to become the world’s most valuable firm. Alphabet’s surge adds further weight to US technology stocks, which have led global markets higher despite geopolitical and trade tensions.
With AI at the core of its strategy and investors signalling confidence in its long-term growth, Alphabet’s $3 trillion valuation marks both a symbolic and strategic milestone for one of the world’s most powerful technology companies.
