He reminded investors to remain cautious during periods of excessive market speculation. Meanwhile, regulatory filings and public data show that Berkshire is significantly increasing its stake in Alphabet, the parent company of Google, making it the third-largest holding of the institution. Buffett pointed out in the interview that in the current market environment, which generally favors speculation and "gambling," it is becoming increasingly difficult to find assets with long-term investment value. He emphasized that due to the natural tendency of humans to speculate, the funds invested by Wall Street capital markets in catering to and cultivating "speculators" have far exceeded those used to nurture rational "investors." As a result, the market pricing mechanism has largely deviated from fundamentals. Industry analysts, including David Kass, a finance professor at the University of Maryland, noted that Buffett's remarks reflect his deep concerns about the abuse of financial derivatives and the increasingly short-term nature of market investment cycles. When discussing the currently hot AI sector, Buffett expressed caution regarding the "arms race" among tech giants like Microsoft, Meta, and Alphabet, which are spending hundreds of billions of dollars on microchips, data centers, and other infrastructure. He emphasized that, unlike early computer software development, the massive capital expenditures in the current AI field are significantly eroding the free cash flow of related companies. Market analysis suggests that such high capital expenditures may force tech giants to cut back on funds originally intended for stock buybacks or even compel them to raise external capital, thereby exacerbating the potential risk of investment returns falling short of expectations. Despite his cautious stance on AI construction costs, Buffett revealed in the interview that Berkshire had decided to invest in Alphabet last year. Data shows that in the nine months ending March 31 of this year, Berkshire significantly increased its holdings in Alphabet to nearly 58 million shares, with a market value of $20.5 billion at that time. In June of this year, under the leadership of Buffett's successor, current CEO Greg Abel, Berkshire made an additional $1 billion investment in Alphabet through a targeted private placement. As of Thursday's close, Berkshire's total holdings in Alphabet had surged to nearly $3.1 billion, surpassing Coca-Cola to become the third-largest holding after Apple and American Express. Buffett explained that based on past performance, Alphabet's win rate in the AI field is likely to far exceed the vast majority of projects promoted by Wall Street. Professional investors analyze that this investment strategy indicates Buffett believes Alphabet has the ability to quickly reduce expenditures and restore strong cash flow when the return on AI investments does not meet expectations. Facing a financial market with high valuations, Berkshire is responding to potential market fluctuations with a refined targeted defensive strategy while maintaining a record cash reserve of $38 billion ### Related Stocks - [GOOGL.US](https://longbridge.com/en/quote/GOOGL.US.md) - [GOOG.US](https://longbridge.com/en/quote/GOOG.US.md) - [BRK.A.US](https://longbridge.com/en/quote/BRK.A.US.md) - [BRK.B.US](https://longbridge.com/en/quote/BRK.B.US.md) - [GGLS.US](https://longbridge.com/en/quote/GGLS.US.md) - [GOOW.US](https://longbridge.com/en/quote/GOOW.US.md) - [GGLL.US](https://longbridge.com/en/quote/GGLL.US.md) - [BRKU.US](https://longbridge.com/en/quote/BRKU.US.md) - [BRKD.US](https://longbridge.com/en/quote/BRKD.US.md) - [GOOY.US](https://longbridge.com/en/quote/GOOY.US.md) - [GOU.US](https://longbridge.com/en/quote/GOU.US.md) - [GOOX.US](https://longbridge.com/en/quote/GOOX.US.md) - [GOOP.US](https://longbridge.com/en/quote/GOOP.US.md) - [MAGX.US](https://longbridge.com/en/quote/MAGX.US.md) - [BRKC.US](https://longbridge.com/en/quote/BRKC.US.md) - [BRKW.US](https://longbridge.com/en/quote/BRKW.US.md) - [07777.HK](https://longbridge.com/en/quote/07777.HK.md) - [MSFT.US](https://longbridge.com/en/quote/MSFT.US.md) - [META.US](https://longbridge.com/en/quote/META.US.md) - [AAPL.US](https://longbridge.com/en/quote/AAPL.US.md) - [AXP.US](https://longbridge.com/en/quote/AXP.US.md) - [KO.US](https://longbridge.com/en/quote/KO.US.md) ## Related News & Research - [Why Google partnered with former Twitter CEO Parag Agrawal's $2 billion AI search startup](https://longbridge.com/en/news/292880383.md) - [Google plans new chip to run Gemini models more efficiently, the Information reports](https://longbridge.com/en/news/293224960.md) - [Warren Buffett Just Gave Away $6 Billion of Berkshire Stock.
