The investigation follows a Reuters report detailing a regulatory crackdown by Chinese authorities on online brokers operating without onshore licenses. Alongside other firms like Futu and Longbridge, UP Fintech faced accusations of illegally facilitating capital movement to foreign markets. The resulting regulatory pressure caused the company's American Depositary Shares to drop sharply during premarket trading and throughout the May 22 session.

Rosen Law Firm argues that shareholders may have suffered financial harm due to allegedly inaccurate business information provided by the company. The firm is currently organizing a class action to recover these losses under a contingency fee arrangement, meaning participants would not incur out-of-pocket legal fees.
