Investors with significant losses from Trip.com stock purchases are actively pursuing lead plaintiff positions in a major securities fraud class action lawsuit arising from China’s antitrust probe into the online travel company. The De Wilde v. Trip.com Group Limited case, filed in the United States District Court for the Eastern District of New York (No. 26-cv-01420), is accepting lead plaintiff nominations from shareholders who purchased stock between April 30, 2024, and January 13, 2026, and suffered substantial losses when the antitrust allegations emerged.
The May 11, 2026 filing deadline is critical for investors who wish to take an active role in directing the litigation—those with losses exceeding $100,000 are particularly encouraged to seek appointment as lead plaintiff, a position that grants them significant influence over case strategy, settlement negotiations, and legal representation. The lawsuit centers on allegations that Trip.com failed to disclose—or actively concealed—the fact that China’s State Administration for Market Regulations (SAMR) was actively investigating the company for abusing its market position. When the antitrust probe was publicly announced on January 14, 2026, the company’s stock price plummeted roughly 17 to 19 percent in a single trading session, dropping $12.90 per share to close at $62.78. This article covers the antitrust violations at issue, the lead plaintiff selection process, critical deadlines, and actionable steps for investors considering participation in this class action.

What Are the Antitrust Allegations Against Trip.com?
The antitrust investigation into Trip.com stems from the company’s allegedly anticompetitive business practices in China’s online travel services market. In September 2025, the Zhengzhou market regulator summoned Trip.com to address violations related to setting unfair restrictions on merchants’ transactions and pricing practices—essentially, allegations that the platform abused its dominant position by imposing unreasonable limitations on how hotel and travel vendors could conduct business. The investigation escalated dramatically when China’s central regulator, the SAMR, formally launched a broader antitrust probe on January 14, 2026, specifically targeting what they characterized as “abuse of market position.” The timing of these regulatory actions is crucial to the securities fraud claim.
Investors allege that Trip.com was aware of the September 2025 Zhengzhou action and the broader regulatory scrutiny but failed to disclose these material facts to shareholders in earnings calls, filings, and public statements during the period leading up to January 14, 2026. A company’s knowledge of pending regulatory investigations that could significantly impact operations and profitability is typically considered material information that must be disclosed. The failure to disclose—or alleged concealment of—this information until the SAMR’s public announcement is the core of the securities fraud allegation.
The Lead Plaintiff Selection Process and Timeline
The lead plaintiff is the investor appointed by the court to represent the entire class of affected shareholders. Unlike passive class members who simply receive any settlement payout, the lead plaintiff actively participates in major decisions: they approve or object to any settlement, select or approve the class counsel (the law firms prosecuting the case), and work with those attorneys to develop litigation strategy. This is not a ceremonial role—lead plaintiffs can significantly influence whether a case settles quickly or proceeds to trial, and they may have input into which legal arguments are prioritized.
Investors with losses exceeding $100,000 who purchased Trip.com stock during the class period (April 30, 2024 through January 13, 2026) are encouraged to file a declaration of interest by May 11, 2026. The court will then evaluate competing lead plaintiff candidates and appoint the one with the largest financial interest in the outcome and the most adequate representation by counsel. Having the most substantial losses does not automatically guarantee lead plaintiff status—courts also assess whether the investor can credibly explain their investment decisions and whether they have a reasonable basis for understanding the litigation. However, investors with six or seven-figure losses typically have a strong competitive position for the appointment.
Financial Impact and Stock Price Collapse
Trip.com’s stock experienced a dramatic and sudden devaluation following the January 14, 2026 announcement of the SAMR antitrust probe. The stock decline of 17 to 19 percent represents a massive single-day loss for shareholders who held the stock at that time. An investor who owned 1,000 shares purchased near the peak of the class period (in late 2025 or early 2026, before the probe became public) would have seen approximately $12,900 per thousand shares evaporate on that single announcement day alone.
The antitrust investigation creates significant uncertainty about Trip.com’s future profitability. If Chinese regulators impose substantial fines—China’s antitrust enforcement actions have historically resulted in penalties representing a percentage of annual revenue—or mandate structural changes to the platform’s business model, the company’s financial performance could deteriorate materially. This regulatory risk, once disclosed to the market on January 14, instantly changed investors‘ assessment of the stock’s value. Class action investors argue that Trip.com should have disclosed this risk much earlier, allowing investors to make fully informed decisions about whether to buy, sell, or hold their shares.
Identifying Whether You Qualify as a Class Member
To be part of this class action, you must have purchased Trip.com stock during the class period of April 30, 2024, through January 13, 2026, and must still hold those shares or have sold them at a loss. Your brokerage account statements or tax forms (Forms 1099-B) will show your purchase dates and prices. Simply purchasing at any time during this window qualifies you as a class member, even if you bought stock near the end of the class period—you don’t need to have held it until the announcement or for any specific time afterward.
However, class members who are interested in becoming lead plaintiff must document their losses. If you purchased 500 shares at an average price of $85 per share in mid-2025 and sold them at $70 following the announcement, your loss would be approximately $7,500—below the $100,000 threshold that firms are emphasizing for lead plaintiff candidates. That doesn’t disqualify you from the class, but it does mean you would not be competitive for lead plaintiff appointment. The distinction matters: ordinary class members typically receive a pro-rata share of any settlement (after attorney’s fees and costs), while lead plaintiffs may have additional rights or in rare cases, additional compensation for their role.
How to File a Lead Plaintiff Declaration and What Happens Next
If you believe you meet the criteria for lead plaintiff status, you will need to submit a sworn declaration (often called a “motion for lead plaintiff”) to the court before the May 11, 2026 deadline. This declaration must detail your investment in Trip.com stock, your purchase and sale dates, the amount of your losses, and your willingness to participate in directing the litigation. Several law firms are handling this case, including Kahn Swick & Foti, LLC; Robbins Geller Rudman & Dowd LLP; Levi & Korsinsky, LLP; and Kessler Topaz Meltzer & Check, LLP—any of these firms can assist you in preparing and filing the necessary paperwork.
One limitation to understand: if you are competing for lead plaintiff status against another investor with substantially greater losses, you have a lower likelihood of being appointed, even if you are equally engaged and credible. Courts generally favor appointing the lead plaintiff with the most at stake, since that person is presumed to have the strongest motivation to ensure a vigorous prosecution of the claims. Additionally, once the lead plaintiff is appointed (usually within a few weeks of the deadline), the court will approve lead counsel—typically one of the firms that has been most actively investigating and promoting the case. This means that your choice of which firm to work with in your lead plaintiff filing can indirectly influence which law firm ultimately represents the class.
Timing Considerations and the Pending Deadline
The May 11, 2026 lead plaintiff deadline is now less than two months away (from the article date of March 29, 2026). This is a firm, court-imposed deadline; filings submitted even one day late will typically be rejected. Investors who are serious about pursuing lead plaintiff status should contact a law firm immediately to begin preparing their declaration. This is not a complicated document—it’s usually just 2–4 pages—but it does require accurate documentation of your stock transactions and a sworn statement, which takes time to organize.
After the May 11 deadline passes, the case will proceed whether or not a lead plaintiff has been appointed. If no sufficient lead plaintiff emerges, the court will often allow class counsel to move forward without a formally appointed lead plaintiff, though this is less common in high-profile securities cases. The class action itself will continue, and any settlement or judgment will benefit class members regardless of whether a lead plaintiff was appointed. However, by missing the deadline, you eliminate any opportunity to shape the litigation’s direction.
Future Outlook and Expected Case Progression
The De Wilde case is in its early stages, and the litigation trajectory depends heavily on whether the appointed lead counsel can survive any motion to dismiss that Trip.com is likely to file. The company will argue that it had no obligation to disclose the Zhengzhou investigation, that the antitrust probe posed no material risk to the company’s business, or that other factors unrelated to the antitrust claims drove the stock price decline. A successful motion to dismiss could end the case; if the court denies the motion, the case will proceed to discovery, where both sides exchange documents and information relevant to the antitrust disclosure claims.
Class action securities cases in federal court typically take 2–5 years from filing to final resolution through settlement or judgment. However, if significant financial evidence emerges that Trip.com knew about regulatory scrutiny and deliberately concealed it, the case could settle much faster. Some securities class actions settle within 18–24 months if the defendant company is anxious to avoid the costs and publicity of ongoing litigation. The lead plaintiff will have important input on whether to accept a settlement offer or push forward to trial, making the role genuinely consequential.
Conclusion
The Trip.com antitrust securities class action offers investors who suffered substantial losses an opportunity to pursue compensation through a structured legal process. The lead plaintiff role, available to investors with losses exceeding $100,000 who purchased stock between April 30, 2024, and January 13, 2026, is a meaningful position that grants real influence over the litigation’s direction and outcome.
With the May 11, 2026 filing deadline approaching rapidly, investors who believe they qualify should act now to contact class counsel and prepare their lead plaintiff declarations. Even if you do not seek lead plaintiff status, you remain eligible to participate in the class action and receive any eventual settlement or judgment. Monitoring the case through the court docket or through periodic updates from the law firms handling the litigation will keep you informed of material developments, settlement negotiations, and important deadlines.
