Microsoft Edges Out D-Wave as Top Quantum Computing Stock

Quantum computing has vast potential to revolutionize numerous technologies, including cybersecurity, artificial intelligence, materials science, and drug discovery. However, this emerging field is still in its early stages of development, making it difficult for investors to predict which companies might thrive over the long term.

D-Wave Quantum and Microsoft are two prominent players in the quantum computing space that have garnered significant attention from investors. D-Wave has recently secured some notable wins, including a 1,120% increase in bookings to $35.5 million in the second quarter. This growth is attributed to its partnerships with companies like AT&T, which plans to use D-Wave's quantum computers for complex optimization challenges across its network operations.

Despite these successes, D-Wave remains a high-risk investment due to its unprofitable status and limited customer base. The company's shares trade at a hefty premium, with a price-to-sales ratio of 610, significantly higher than the average P/S ratio of around 8 for technology sector companies.

Microsoft, on the other hand, has made significant strides in quantum computing, including developing a topological superconductor that can create more stable qubits. The company's Azure cloud system for quantum computing services has already been commercialized, allowing companies to rent the service for advanced research. Microsoft's success in this area is expected to drive growth in its quantum computing business, given its large customer base and established reputation as a leader in cloud infrastructure.

With its strong financials, including $19.6 billion in free cash flow and a price-to-earnings ratio of 27, Microsoft appears to be a more attractive investment opportunity compared to D-Wave. As the quantum computing market continues to develop over the next five years, Microsoft's position as a leader in this space makes it an appealing choice for investors.

Microsoft's Azure surpassed $100 billion in annual sales in fiscal 2026, representing a 41% increase from fiscal 2025. This significant growth demonstrates the company's ability to adapt and innovate in the rapidly evolving technology landscape.
