As early as the beginning of September, Dan Bin stated on social media that the gap between domestic internet giants and global giants has been widening in recent years, and it is very meaningful to strive to catch up and achieve new historical highs.
Dan Bin cited Alibaba as an example, noting that its market capitalization was once close to that of American internet giants, but now it is only 15.25% of Amazon's . As of September 15, 2025, Apple... Amazon, Google, Facebook, and Microsoft The combined market capitalization of these five companies is approximately $14.698 trillion, while the combined market capitalization of China's BAT (Baidu, Alibaba, Tencent) is approximately $1.18 trillion.

Dan Bin believes that Broadcom's customized ASIC chips and Nvidia's GPUs are complementary rather than substitutive, and the two will develop in parallel to meet the differentiated needs of AI infrastructure.
As of the end of the third quarter, Dan Bin's top ten holdings were mainly technology stocks, with Nvidia and Google remaining his top two holdings, valued at $236 million and $224 million respectively, accounting for 35% of his total holdings. Following closely behind were 3x leveraged FANG+ index ETNs and 3x leveraged Nasdaq ETNs. 100ETF, Meta, Microsoft , Tesla Apple , COINBASE, and Alibaba ranked sixth through tenth.
Amidst the debate over an AI "bubble," Dan Bin firmly believes that the risk of missing out on an era far outweighs the risk of a bubble. (Artificial Intelligence ) This is not a short-term trend, but a major technological revolution that may last 10 to 30 years.
In the latest monthly report, Huang Haiping, Director of Investment Research at Orient Harbor, wrote that people are accustomed to viewing problems with a static perspective. This hinders our understanding and insight into the changes of the times, causing us to not only overlook opportunities when they arise but also ignore risks when they are exposed.
Huang Haiping pointed out that OpenAI recently staged a spectacular "alliance and consolidation" drama—a high-stakes gamble on AI computing power, with OpenAI successively partnering with Oracle. SoftBank, Coweave, and SoftBank signed a cooperation agreement, thus creating a century-long alliance. The debate over the computing power bubble is destined to span the entire development cycle of the AI era, and it is believed that the potential demand for AI computing power far exceeds the current supply.
"History doesn't simply repeat itself, but it does share a common rhythm. OpenAI's high-stakes gamble is merely a footnote in the development of this AI computing power bubble. Regardless of the outcome, it may not change the direction of history. Currently, the AI computing power bubble is still in its early stages, with reasonable valuations. The pressure on the economy and industry remains relatively mild. More and more AI applications are growing at an ever-increasing revenue growth rate, and the financing structure is still very healthy. At this stage of development, we have no reason not to embrace it actively," said Huang Haiping.
