Warren Buffett spent years calling Google one of his biggest misses. Now, Berkshire Hathaway has finally made a move, disclosing a new stake in Alphabet valued at approximately $4.34 billion in its latest 13F filing.

This marks the first time Berkshire has taken a position in Google's parent company, a significant shift for a firm whose chairman long avoided most tech stocks. The $10 billion figure circulating on social media does not match the actual regulatory filing.

Berkshire's investment thesis has always centered on durable, cash-generating businesses with competitive moats. Alphabet checks those boxes now more than ever, with growth in cloud services and artificial intelligence. The company's recent quarterly results have been strong, showing revenue growth, margin expansion, and disciplined capital allocation.

Berkshire already held a massive stake in Apple. This Alphabet purchase extends its technology exposure beyond a single company, diversifying its portfolio.
