After struggling through most of 2026 due to investor concerns about commercialization and macroeconomic headwinds, quantum computing stocks are gaining renewed attention following October developments. IonQ announced a $1.3B acquisition of cybersecurity firm Elisity, Xanadu partnered with GlobalFoundries for high-volume photonic component production, and D-Wave launched a gate-model simulator beta program. These catalysts signal improving commercial traction in the sector, though challenges around hardware scalability and profitability persist.

Xanadu Quantum Technologies stock surged 17% after announcing a multi-year manufacturing partnership with GlobalFoundries to scale production of photonic quantum computing chips from lab prototypes to 300mm industrial production. However, the stock remains down 45.7% over the past month, and the company faces significant challenges including minimal revenue ($1.5M last quarter), substantial losses ($42.1M), and no expected commercial sales until 2029-2030.

Xanadu Quantum Technologies stock fell 56.2% in September 2026, primarily due to the expiration of a post-merger lockup period on September 22 that allowed early investors and insiders to sell shares. Despite the decline, the company announced positive developments including collaborations with ASML and AMD, and received an outperform rating from RBC Capital with a $16 price target.

Xanadu Quantum Technologies announced that Chief Operating Officer Rafal Janik has entered into an automatic securities disposition plan to sell up to 312,914 Class B Shares. The plan, established in compliance with securities laws, permits sales to commence on or after December 29, 2026, and will terminate by December 31, 2027. Sales will be executed by an independent securities broker according to pre-arranged instructions.
