Berkshire’s Rare Tech Move Sends Alphabet Stock to All-Time High

Alphabet shares surged to a record high on Monday, climbing nearly 6% after Berkshire Hathaway disclosed a new multibillion-dollar stake in the Google parent company. The purchase, totaling 17.85 million shares valued at approximately $4.9 billion, marks one of Berkshire’s final large investments under Warren Buffett’s leadership — and a notable shift for a conglomerate traditionally cautious about high-growth tech stocks.

Berkshire’s move represents a major endorsement of Alphabet’s expanding artificial intelligence strategy during a period of heightened scrutiny across the tech sector. While many investors have begun questioning whether the rapid rise of AI-driven valuations is sustainable, Berkshire’s investment signals confidence in Alphabet’s fundamentals and its long-term ability to capitalize on AI innovation.

The investment also stands out given Berkshire’s historic stance on technology. Although Apple remains Berkshire’s largest holding, Buffett has long viewed it as more of a consumer products company than a pure tech play. A direct investment in Alphabet, however, reflects a meaningful step toward embracing companies at the center of the AI revolution. Market strategists point out that the move aligns with value-investing principles, given Alphabet’s comparatively attractive valuation relative to other AI frontrunners.

Investor sentiment around tech has become more cautious in recent months. Business leaders and market analysts have warned that the AI boom — powered by heavy data-center spending and ambitious product pipelines — could be creating inflated expectations. The Roundhill Magnificent 7 ETF, which tracks top tech names such as Microsoft, Nvidia, and Alphabet, has been mostly flat since September after significantly outperforming the broader market earlier in the year.

Despite the broader slowdown, Alphabet has stood out as one of the strongest performers among the “Magnificent Seven” stocks. Shares have surged nearly 14% in the current quarter and are up 46% year-to-date, making it the group’s top performer. Analysts attribute this strength to Alphabet’s accelerating AI investments, robust cloud division growth, and its ability to leverage its massive advertising business to fund further innovation.

Alphabet also trades at a relative discount compared to its peers, with shares valued at roughly 25 times forward earnings estimates. Microsoft trades at 29 times, while Nvidia approaches 30 — making Alphabet an appealing option for an investor focused on balancing growth potential with valuation discipline.

CFRA analysts highlight that Berkshire’s investment validates Alphabet’s strategic direction, particularly around Google Cloud and the expanding Gemini AI ecosystem. Recent earnings revealed that AI-powered tools and infrastructure investments are helping transform Google Cloud into a major growth engine, reversing its earlier status as a distant third player in the cloud market.

The move also reflects a bit of unfinished business for Buffett, who has previously acknowledged regretting missing the chance to invest in Google early on. With Berkshire preparing for leadership transition as Greg Abel is set to assume the CEO role at the end of 2025, the investment may represent a final major pivot toward companies leading the next technological era.

Alphabet’s rally could add roughly $180 billion in market value if gains hold. And with Berkshire’s reputation for long-term conviction, the investment has quickly captured the attention of both institutional and retail investors — offering a strong signal of confidence amid an increasingly cautious tech landscape.

Google Faces Antitrust Showdown Over Online Ad Dominance in Landmark Trial

Alphabet’s Google is set to battle U.S. antitrust prosecutors in a highly anticipated trial starting today in Alexandria, Virginia. The Justice Department aims to prove that Google has unlawfully monopolized the online advertising technology space, stifling competition and manipulating ad auctions to its advantage. This trial marks the tech giant’s second major antitrust clash with the government in recent years, underscoring ongoing efforts by U.S. enforcers to challenge Big Tech monopolies.

At the heart of the case is Google’s dominance over the digital infrastructure that powers more than 150,000 online ad sales per second, a crucial revenue source for countless websites. The Justice Department alleges that Google achieved its powerful position through strategic acquisitions, restrictive practices, and auction manipulation, allowing it to dominate online ad markets. These practices, prosecutors argue, have given Google an unfair advantage over competitors and harmed both publishers and advertisers, leading to higher costs and reduced choice in the digital advertising ecosystem.

Google, however, denies these allegations, asserting that its efforts to innovate and expand its advertising technology were both legal and necessary to better serve its customers. The company argues that the government is mischaracterizing its actions and overlooking the competitive nature of the digital advertising industry. According to Google, the advertising landscape has changed dramatically, particularly with the rise of connected TV and mobile app ads, where competition is fierce.

If the U.S. District Court finds that Google violated antitrust laws, the consequences could be severe for the tech giant. One of the potential outcomes is that Google may be forced to sell off its Google Ad Manager platform, which includes its publisher ad server and ad exchange. Such a move would be a significant blow to Google’s ad tech business, which generated $20 billion in 2020, accounting for 11% of its total revenue that year. A ruling against Google could reshape the digital advertising landscape and open the door for more competition in the ad tech space.

Both Google and the government have assembled high-powered legal teams to argue their cases. Google’s defense is led by Karen Dunn, a prominent lawyer from Paul, Weiss, known for her role in preparing high-profile Democrats for debates. The government’s legal team is headed by Julia Tarver Wood, a veteran trial attorney who joined the Justice Department last year. Witnesses from across the digital advertising industry are expected to testify, including representatives from competitors like The Trade Desk and Comcast, as well as publishers such as News Corp and Gannett, who claim to have been negatively impacted by Google’s practices.

This case is part of a broader wave of antitrust actions aimed at reining in the power of Big Tech companies. Just last month, the Justice Department secured a ruling against Google in a separate case involving its dominance in online search. The U.S. Federal Trade Commission is also pursuing legal actions against other tech giants, including Meta and Amazon, as part of a concerted effort to challenge what the government sees as monopolistic practices in the tech industry.

The outcome of the Google trial could have far-reaching consequences not only for the future of digital advertising but also for other ongoing antitrust actions. A decision in favor of the government could embolden regulators to pursue more aggressive actions against other tech companies, while a ruling in Google’s favor might signal a more hands-off approach to tech industry regulation in the future.

This antitrust case is closely tied to previous allegations and rulings involving Big Tech companies, including a recent decision involving Google’s dominance in online search.
