NEW YORK, Jan 2, 2026, 10:35 ET
- IBM is targeting a “quantum advantage” demonstration in 2026, a near-term milestone investors are watching.
- Zacks highlighted IBM, IonQ and Nvidia as quantum-linked plays for 2026 as funding and enterprise interest build.
- The sector remains early-stage and volatile, with most companies still unprofitable.
IBM’s plan to demonstrate “quantum advantage” in 2026 is emerging as a key waypoint for investors tracking quantum computing stocks at the start of the new year.
The renewed focus comes as market commentators look for the next big technology theme beyond artificial intelligence, pointing to a mix of big tech and smaller specialists with exposure to quantum development.
2026 matters because the industry has promised a string of technical checkpoints, while governments and corporations continue to fund research even as most quantum businesses remain in the red.
Quantum computers use quantum bits, or qubits, which can exist in multiple states at once rather than only as ones and zeros. That can speed up certain calculations, but qubits are fragile, making error reduction and error correction central hurdles.
“Quantum advantage” refers to a clear demonstration that a quantum system — often paired with traditional computers — can outperform classical approaches on a practical task. A fault-tolerant system is designed to keep calculations reliable by correcting errors as it runs.
In early trading on Friday, IBM shares were down about 1.4% and IonQ fell about 1.5% by 10:26 a.m. ET, while Nvidia was up about 1.9%. The Defiance Quantum ETF, which tracks the theme, rose about 1.4%, according to market data.
In a Dec. 31 note, Zacks Investment Research writer Urmimala Biswas argued quantum is moving from a scientific project toward an investable theme, and flagged IonQ, IBM and Nvidia as names tied to 2026 progress markers. She wrote the sector increasingly resembles “a high-beta, early-cycle technology bet” — shorthand for stocks that tend to swing more than the broader market. 1
Zacks pointed to IonQ’s trapped-ion approach, which uses electrically charged atoms as qubits, and said the company’s systems are accessible through cloud marketplaces including Amazon’s AWS, Microsoft’s Azure and Google Cloud. The note cited IonQ’s published roadmap targeting systems in the 100 to 256-plus physical qubit range by 2026.
IBM is not a pure-play quantum company, but Zacks said it has clear 2026 catalysts, including the goal of demonstrating quantum advantage through improved hardware and integration with classical high-performance computing workflows.
A Jan. 1 column by Motley Fool analyst Timothy Green also highlighted IBM’s quantum roadmap, citing the company’s plan to show a “clear example of quantum advantage” in 2026 and its longer-term timeline for building a fault-tolerant machine. Green wrote IBM disclosed it was nearing $1 billion in cumulative quantum-related signings and pointed to the company’s November unveiling of its 120-qubit Nighthawk quantum processor. 2
For Nvidia, Zacks cited CUDA‑Q, an open-source platform meant to link quantum processors with GPU-powered systems so researchers can run hybrid quantum-classical algorithms. The note also pointed to Nvidia’s quantum simulation tools and its announcement of an Accelerated Quantum Research Center in Boston in 2025.
The picks underline how early quantum activity is often monetized through developer tools and cloud access rather than standalone hardware sales. That dynamic can favor large platforms that already sell computing services and software, even if fully fault-tolerant quantum machines remain years away.
A separate Dec. 30 Barron’s column also highlighted quantum pure plays such as IonQ, D-Wave Quantum and Rigetti Computing, underscoring how investor interest has spread across both big tech and smaller listed developers. 3
