Summary
Galaxy Digital CEO Michael Novogratz has acknowledged that the AI investment boom is a bubble but maintains that the upward trend is not yet over. According to Bloomberg News, Novogratz described AI as "the greatest bubble of our lifetime" at the Greenwich Economic Forum in Greenwich, Connecticut, this week. He nonetheless argued that it is not yet time to reduce AI exposure, stating, "Bubbles don't end the way they are right now. I know how bubbles end. They end dramatically, and we are not at that stage yet." He assessed AI-related stocks as still cheap based on price-to-earnings ratios and said, "If you haven't invested in AI, you might as well just go home and stick your head in a bucket of ice water."

The rally has been sharp. The S&P 500 hit a record high the previous day, driven by AI-related shares, and NVIDIA's market capitalization approached approximately 8,040 trillion won, according to the report.

View from the bearish side: Ray Dalio, founder of Bridgewater Associates, the world's largest hedge fund, took a more cautious stance at an event in Singapore. He described the AI investment craze as a "classic bubble" and said rising interest rates are moving the market closer to the point where the bubble could burst. "We are still before that stage, but we are approaching it. I think we've gotten quite close," Dalio said.

Wall Street opinion is divided. Bank of America strategists advised investors worried about a potential tech stock plunge to use stock derivatives to participate in upside while reducing the risk of a bubble collapse. Hou Wey Fook, Chief Investment Officer at DBS Group, argued that AI tech stocks are still far from a bubble, noting that NVIDIA's price-to-earnings ratio is close to its lowest level since 2016 and that its earnings growth next year is expected to reach 70%.
