Is D-Wave Quantum stock a buy right now?
For investors eager for quantum-computing exposure in 2026, D-Wave continues to look like one of the top plays in the space. The company's quantum-annealing approach to computing gives it better near-term commercialization opportunities than many of its competitors, and D-Wave is also investing in more ambitious approaches to quantum computing that could turn into even more powerful sales drivers over the long term. As of last year's third quarter, the company also had $836 million in cash and short-term equivalents -- giving it a solid balance sheet to work with it as it pursues new quantum technologies and commercialization initiatives.

Key Data Points
On the other hand, D-Wave stock is probably only a good fit for investors with very high risk tolerance. While quantum computing has the potential to be revolutionary, the technology remains in a relatively nascent state. Along with the potential for macroeconomic and geopolitical volatility, lofty valuation multiples and growth expectations suggest that shares could see high levels of volatility in 2026.
