PANews reported on May 22 that, according to market analysts, if future regulatory policies prevent mainland Chinese investors from holding or trading US securities through cross-border brokerages such as Futu Securities and Tiger Brokers, client assets on these platforms may face migration or disposal needs, potentially involving approximately $175 billion in US stock assets. Analysts believe this figure is based on the total assets under management on these platforms and the proportion of mainland users, and does not represent the actual amount of selling. Market participants point out that even with stricter regulations, investors may still continue to hold assets through asset transfers and account migrations, therefore the actual selling pressure may be far lower than theoretically estimated. Currently, relevant regulatory policies do not require investors to forcibly sell their US stock holdings.

As of the end of 2025, Futu Securities had approximately US$158.4 billion in client assets, and Tiger Brokers had approximately US$60.8 billion. Referring to CMB International's previous disclosure that Futu's Greater China client assets accounted for over 80%, the market estimates, using the same proportion, that the combined Greater China client assets of the two platforms total approximately US$175 billion.
