QBTS investors who bought D-Wave Quantum Inc. securities during a specific 2026 window have until December 15, 2026 to seek lead plaintiff status in a securities fraud lawsuit, according to a November 6, 2026 notice from Rosen Law Firm. The firm says purchasers between February 26, 2026 and August 25, 2026 may be entitled to compensation and may be able to pursue the case without paying out-of-pocket fees or costs under a contingency fee arrangement.
What happened?
On November 6, 2026, Rosen Law Firm said it is reminding investors that the class period for D-Wave Quantum Inc. runs from February 26, 2026 through August 25, 2026, inclusive. The notice says the key date investors should watch is December 15, 2026, which is the lead plaintiff deadline.
The company involved is D-Wave Quantum Inc., listed on the NASDAQ under the ticker QBTS. The notice was issued in New York.
Who can participate in the case?
According to the firm, the notice applies to purchasers of D-Wave securities during the stated class period. That means investors who bought shares within that window are the group being alerted to possible legal action.
Rosen Law Firm says investors may be entitled to compensation if they qualify. The firm also says the case may be handled on a contingency fee basis, which means eligible investors would not pay out-of-pocket fees or costs upfront.
Key dates investors are watching

Why does this matter for traders?
For retail investors, a securities lawsuit notice can matter even if the stock is no longer in the spotlight. It can affect how shareholders assess risk, legal overhang, and possible recovery opportunities tied to past purchases.
In this case, the notice does not provide allegations or case details beyond the class period and deadline. It does, however, signal that investors who traded QBTS during the period named by the firm may want to check whether they are covered by the suit.
What should investors do next?
Based on the notice, investors who purchased D-Wave Quantum securities between February 26 and August 25, 2026 may want to review their records and note the December 15, 2026 deadline. The firm says eligible buyers may be able to seek compensation without upfront costs, but participation depends on whether they fit the class-period criteria.
For traders, the practical takeaway is simple: if you held or bought QBTS during the dates named in the notice, the clock is running toward the lead plaintiff deadline.
