Google leads monster week for tech, pushing megacaps to combined $21 trillion in market cap

This past week marked a significant milestone for the tech industry as major players saw substantial market gains. The resolution of Google's antitrust case triggered a remarkable rally for Alphabet and Apple, while Broadcom celebrated a lucrative new contract worth $10 billion. Tesla's stock also benefited from a proposed compensation package for CEO Elon Musk, demonstrating the dynamic nature of the tech market. Collectively, the eight tech giants in the U.S. that are valued at over a trillion dollars experienced an increase of $420 billion in market capitalization, bringing their total worth to a staggering $21 trillion. This surge reflects the companies' growing dominance, as they now represent approximately 36% of the S&P 500—a level of concentration that, according to Howard Silverblatt, senior index analyst at S&P Dow Jones Indices, has no historical comparisons. Interestingly, Alphabet's share price jumped by 9% on Wednesday, directly linked to the U.S. government's ongoing attempts to regulate Big Tech. This effort has included various antitrust allegations against Google, Apple, Amazon, and Meta since 2020. A year prior, Google faced a significant loss in court against the Department of Justice, marking a pivotal moment in tech antitrust history since the Microsoft case from two decades ago. Despite this setback, U.S. District Judge Amit Mehta's recent ruling noted that Google would not be required to divest its Chrome browser. Instead, the company faces a more measured penalty, which includes sharing search data with competitors. This decision not only buoyed Alphabet's stock but also positively impacted Apple, allowing the two companies to maintain their lucrative agreement in which Google pays Apple billions to remain the default search engine on iPhones. With Alphabet's shares climbing over 10% for the week and Apple's rising by 3.2%, the Nasdaq index saw a boost of 1.1%. Analysts from Wedbush Securities highlighted that this ruling alleviated substantial concerns surrounding Google's stock, paving the way for potential partnerships in artificial intelligence, particularly regarding Google's Gemini AI models. Mehta emphasized that the rise of generative AI has shifted the competitive landscape, introducing new challengers that could disrupt Google's longstanding market leadership. Investors seemed unfazed by a separate antitrust issue in Europe, where Google was fined €2.95 billion ($3.45 billion) for anti-competitive practices in its advertising technology sector. Meanwhile, Broadcom's stock skyrocketed following an impressive earnings report, with CEO Hock Tan announcing a new $10 billion contract. Analysts believe this contract is linked to OpenAI, marking Broadcom's entry into the growing AI market, alongside its established partnerships with tech giants like Google and Meta. The company's stock surged 13% this week, contributing to a remarkable 120% increase over the past year, and elevating its market cap to approximately $1.6 trillion. In contrast, Nvidia experienced a downturn, with its shares falling over 4% this week, marking four consecutive weeks of declines despite remaining the largest company by market capitalization at over $4 trillion. Microsoft's stock also continued to slide, down for five straight weeks but still up 21% year-over-year. Tesla's shares rose by 5% this week, largely due to an announcement regarding a new pay plan for Musk, potentially worth up to nearly $1 trillion. This compensation package, which is contingent on significant increases in Tesla's market value, aims to keep Musk engaged and focused on the company's future amid challenges from rising competition in the electric vehicle market.
