Amid the slowing down of U.S. tech stocks such as Nvidia due to controversy over the artificial intelligence (AI) bubble, Google’s parent company Alphabet rose to the third place in market capitalization, beating Microsoft (MS).
As the recently released next-generation AI model ‘Gemini 3’ has received favorable reviews in the market, the stock price seems to be on the rise.
Alphabet closed at $299.65 on the New York Stock Exchange on the 21st, up 3.33% from the previous trading day.
Alphabet’s stock price has been breaking new highs since August this year, and its growth rate from the beginning of the year was close to 60%, the highest among mega-cap technology stocks.
As of that day, Alphabet’s market capitalization was $3.62 trillion, and the pace of its expansion has accelerated since it surpassed $3 trillion in 21 years since it was listed in September.
Alphabet’s recent rise is driven by Google’s favorable reviews for its new AI model Gemini 3, which was unveiled on the 18th.
The Gemini 3 was released in two lineup: “Pro” with a large number of new functions added and “DeSink” with enhanced inference performance. The Gemini 3 Pro scored 1,501 points on the LM Arena Leaderboard, an AI model evaluation site, surpassing the previous No. 1 Gemini 2.5 Pro.
In the “HLE” test, a high-level reasoning and problem-solving ability test, Gemini 3 Pro recorded 37.5% and D-Sync 41%, ahead of OpenAI’s “GPT 5 Pro,” which was only 30.7%.
The news that Berkshire Hathaway, led by Warren Buffett, recently included a new alphabet also raised the market’s attention. Analysts say it is unusual for Buffett, who has adhered to the philosophy of investing in value stocks, to choose Alphabet, a technology growth stock. Berkshire Hathaway purchased 17.85 million new shares of Alphabet during the period, according to the Securities and Exchange Commission’s 13F disclosure in the third quarter of this year. Berkshire Hathaway’s share of Alphabet in its entire portfolio has entered the top 10 at 1.62%, while Apple, the largest existing holding, has declined.
Meanwhile, Microsoft’s stock price fell 12.9% from its high point in late October as it was directly hit by the AI bubble theory. It is the first time in seven years that Alphabet’s market cap has surpassed MS since 2018.
