Approximately a year ago, Warren Buffett’s Berkshire Hathaway made a surprising move by investing in Alphabet, a position that has since grown into one of its top five holdings. Despite Buffett’s historical aversion to tech, the article highlights three compelling reasons why Alphabet remains an attractive buy for long-term investors today. These include the explosive growth of Google Cloud, innovative future opportunities like Waymo’s self-driving technology, and the company’s proven resilience in navigating significant antitrust challenges.
In a notable shift from his traditional investment philosophy, Berkshire Hathaway (BRKA, BRKB), under the guidance of Warren Buffett himself, initiated a significant position in Alphabet (GOOG, GOOGL) approximately a year ago in the third quarter of 2024. This initial investment has since been amplified, with Alphabet now proudly ranking among Berkshire's top five holdings. Despite Buffett's long-standing reputation for sidestepping tech stocks, his personal involvement in this acquisition underscored a profound belief in the tech giant's future. While Alphabet has demonstrated strong performance over the past year, its long-term potential remains robust. Let's delve into three compelling reasons why this stock continues to be a strong buy today.

1. Alphabet's Cloud Business is Soaring to New Heights
While Alphabet is globally recognized for its dominant Google search engine and YouTube's substantial advertising contributions, its most dynamic growth engine in recent quarters has been Google Cloud. This cloud computing segment is not just growing; it's accelerating. In the second quarter alone, Alphabet's total revenue hit $119.8 billion, a robust 24% year-over-year increase. Crucially, Google Cloud contributed $24.8 billion to these sales, marking an astounding 82% surge from the prior year.
Though it may not hold the largest market share in the cloud industry, Google Cloud has carved out a niche with its exceptional artificial intelligence (AI) services. Alphabet is strategically intensifying its focus here, as evidenced by its increased capital expenditure guidance for 2026, now projected between $195 billion and $205 billion. With an unwavering demand for AI computing capacity and a formidable backlog of $514 billion at the end of Q2, Google Cloud is poised for sustained, powerful performance for the foreseeable future.
2. Abundant Growth Opportunities Beyond Core Businesses
Beyond its lucrative advertising and booming cloud sectors, Alphabet boasts a portfolio rich with long-term potential. A prime example is Waymo, the company's pioneering subsidiary in self-driving vehicles. Operating across more than a dozen U.S. cities, Waymo commands a robotaxi fleet that surpasses even that of electric vehicle leader Tesla (TSLA).
The robotaxi industry is still in its nascent stages, but Waymo's extensive fleet provides a crucial competitive advantage: a wealth of real-world data. This data is invaluable for training and refining its self-driving software, creating a virtuous cycle where more cars on the road lead to more data and better technology. While the development of autonomous vehicles is capital-intensive, Waymo's ability to scale and achieve high utilization over the next decade could unlock substantial new revenue streams for Alphabet. This commitment to continuous innovation across diverse areas underscores Alphabet's bright future.
3. Alphabet Continues to Navigate Legal Challenges Effectively
Alphabet has faced its share of legal battles, particularly antitrust lawsuits in the United States. A recent and significant victory saw a federal judge reject the U.S. Government's bid to force Alphabet to divest AdX, its online ad space marketplace. This outcome is not an isolated incident; Alphabet has a track record of emerging from major antitrust cases largely unscathed.
While the company still contends with ongoing legal challenges, including lawsuits concerning its YouTube platform's alleged harm to users, its adeptness at navigating these complex legal landscapes is a testament to its robust operational and legal strategies. Given this proven resilience, combined with its excellent underlying businesses and promising long-term opportunities, Alphabet stock remains a compelling investment.
