3 Best Quantum Stocks to Watch as the Quantum Computing Market Accelerates

IonQ, Alphabet, and IBM lead the quantum computing charge, drawing savvy investors as the market surges past $5.59 billion in 2026.

Race for Quantum Dominance

Quantum computing promises to crack problems classical machines can’t touch, from drug discovery to optimization. Yet the field remains nascent, with systems stuck at hundreds of qubits versus the million-plus needed for breakthroughs. Pure-play IonQ shines here, trading at $34.11 on February 14 with a $12 billion market cap after an 8.98% jump. 

Its game-changer: IonQ is planning to acquire SkyWater Technology for $1.8billion, enabling vertical integration from chip design to manufacturing. 

Diversified Powerhouses

Alphabet (GOOG), at $305.96 and a $3.7 trillion cap, pours endless resources into its Willow chip, which slashes errors as qubits scale proven in 7×7 grids. IBM, steady at $262.24 with a 1.0% yield, dominates software: its open-source Qiskit SDK boasts 13 million downloads and 69% developer preference. 

McKinsey estimates that quantum computing technology could generate $97 billion in revenue by 2035, up from $4 billion in 2024. IonQ is focused on improving the accuracy of its quantum computers, claiming to be “the first and only quantum computing company” to achieve 2-qubit gate fidelities of 99.99% in October of last year. 

Bright Horizon Ahead

IonQ, Alphabet, and IBM are three quantum computing stocks that are worth purchasing right now; each has advantages of its own. Investors will need to be patient as the field develops because quantum computers still need to advance in the upcoming years.

However, the Enterprise Quantum Computing Market increased from $2.10 billion in 2025 to $2.69 billion in 2026. It is expected to grow at a 28.68% CAGR through 2032, reaching $12.31 billion.
