Motley Fool Picks 3 Quantum Stocks for H2 2026 as Market Eyes $2.7 Trillion AI Opportunity
1 articles · Updated · The Motley Fool · Jul 7
Summary
Three companies—Nvidia, IonQ and newly public Quantinuum—were singled out as the top quantum-computing stocks to watch in the second half of 2026.
McKinsey estimates quantum AI could create $1.3 trillion to $2.7 trillion in economic value by 2035, underpinning the case that quantum systems can extend AI into harder computational problems.
Nvidia’s appeal rests on cuQuantum and its role in hybrid quantum-classical computing, where demand for classical hardware should grow as quantum machines need simulation, error correction and processing support.
IonQ offers one of the few pure-play bets through trapped-ion systems on major cloud platforms, but its aggressive expansion comes with high valuation expectations while the company remains early-stage and unprofitable.
Quantinuum, which listed last month, is pitched as a steadier option because of backing from investors including JPMorgan, Amgen, Mitsui and Nvidia, though post-IPO trading could stay volatile as commercialization develops.
With quantum firms still unprofitable, is the projected multi-trillion dollar market just fueling another tech bubble?
If AI is building quantum computers, what happens when quantum computers start building an even smarter AI?
As the US and China race for quantum supremacy, who is winning the fight to secure our digital world?

Overview
The quantum computing sector is set for strong growth in the second half of 2026, with its total addressable market expanding rapidly. This surge is fueled by the massive opportunity in artificial intelligence, which is creating renewed interest in quantum technologies. A key turning point came when Nvidia declared quantum as its next focus, lending its reputation and engineering strength to the field. Nvidia’s launch of NVIDIA Ising marked a major milestone, fundamentally changing how investors view the sector. As a result, the synergy between AI and quantum computing is driving both market excitement and investment momentum.
