Top 3 quantum computing stocks for 2026

Quantum computing is entering a more consequential phase as the industry moves toward 2026. 

In this case, after years of heavy research spending and experimental deployments, the focus is shifting to scalability, real-world applications, and national strategic priorities.

At the same time, governments are increasing funding as quantum technology becomes central to national security and AI sovereignty, while enterprises are beginning to test quantum tools for optimization problems that exceed classical limits. 

The sector is also drawing investor interest, with a small group of companies demonstrating proven technical capability, commercial traction, and financial strength.

IonQ (NYSE: IONQ)

IonQ (NYSE: IONQ) enters 2026 with one of the most complete growth profiles in the sector. Through its acquisition of Oxford Ionics, the company is advancing high-fidelity trapped-ion systems beyond 64 qubits, strengthening its position as a scalable, pure-play hardware provider. 

Additionally, IonQ’s revenue mix is shifting toward direct enterprise and government contracts, improving visibility. For instance, in Q3 2025, IonQ reported revenue of $39.9 million, up 222% year over year, alongside a $1.1 billion net loss tied to aggressive investment. 

The firm also raised its 2025 revenue forecast to $106 million–$110 million and maintained an adjusted EBITDA loss midpoint of about $211 million. 

Meanwhile, IonQ shares were trading at $46 as of press time, up more than 6% year-to-date.

D-Wave Quantum (NYSE: QBTS) 

D-Wave Quantum (NYSE: QBTS) takes a more application-focused approach, emphasizing near-term adoption over theoretical leadership. 

The technology company’s Advantage2 system increases the complexity of optimization problems it can handle, supporting customers who already use quantum tools in production. 

Meanwhile, deeper integration into enterprise workflows is driving recurring usage and higher switching costs, while international expansion is reducing reliance on U.S. government demand. 

This practical positioning has resonated with investors seeking tangible utility. At the last close, QBTS shares stood at $23.74, up nearly 150% year-to-date.

Rigetti Computing (NASDAQ: RGTI)

Finally, Rigetti Computing (NASDAQ: RGTI) represents a more asymmetric opportunity. Progress toward higher-fidelity modular superconducting systems could rebuild confidence if execution milestones are met. 

Government support remains pivotal, with recent contracts including a $5.8 million Air Force Research Lab deal for quantum networking and earlier Department of Energy agreements for fusion energy simulation. 

These deals signal growing confidence in Rigetti’s superconducting and hybrid quantum-AI technologies among the defense and energy sectors.

Strategic partnerships also remain a possibility. With expectations already muted, positive developments could drive a sharp re-rating. 

RGTI shares are up 17% in 2025, trading at $23.

Together, these companies reflect distinct paths to potential leadership in quantum computing as investor attention intensifies heading into 2026.
