Shares of companies involved in quantum computing jumped significantly on April 14th and 15th. This increase followed NVIDIA’s release of Ising, a new, openly available family of quantum AI models, which boosted investor confidence that practical quantum computing is developing more quickly than expected.
Summary
- IonQ closed up 20.95% to $43.25, D-Wave Quantum gained 22.63% to $20.81, and Rigetti Computing rose 13.28% to $19.11, all driven by the NVIDIA Ising announcement.
- D-Wave’s trading volume hit 90.2 million shares, approximately 227% above its three-month average, reflecting a sector-wide rerating rather than isolated stock-specific moves.
- TD Cowen analyst Krish Sankar called NVIDIA Ising a “critical catalyst” that could speed up commercialization of the quantum industry.
Quantum computing companies saw their biggest stock gains of 2026 in mid-April. Shares of IonQ, D-Wave Quantum, and Rigetti Computing all increased significantly on April 14th and 15th following NVIDIA’s release of Ising, a new, publicly available AI model designed to improve the accuracy of quantum processors.
Shares of several quantum computing companies saw significant gains today. IonQ increased by 20.95%, closing at $43.25. D-Wave Quantum jumped 22.63% to $20.81, with trading volume much higher than usual – about 227% above its average for the past three months. Rigetti Computing also rose, increasing by 13.28% to close at $19.11.
Why the Market Reacted So Sharply
NVIDIA Ising focuses on solving the main challenges holding back practical quantum computers: fixing errors and calibrating the processors. Currently, these tasks require a lot of hands-on work and restrict how large and dependable quantum computers can be.
NVIDIA is helping companies like IonQ, D-Wave, and Rigetti speed up their development of quantum computers. By offering readily available AI models, NVIDIA cuts down the time needed to prepare these systems from days to just hours, and significantly improves their ability to correct errors – up to three times better, in fact. This is crucial for these companies, as they’re working to prove their technology is commercially viable before they run out of funding.
According to TD Cowen’s Krish Sankar, Ising could significantly accelerate the development and use of quantum technology. Craig Ellis of B. Riley Securities told MarketWatch that these models have the potential to drive widespread quantum adoption in the future.
IonQ Had Additional Tailwinds
IonQ had a particularly successful day, boosted by two major announcements. First, they confirmed they’d received a contract from DARPA’s program focused on diverse quantum computing designs. Second, they revealed a new technology that connects two separate trapped-ion quantum systems using light, which is an important advancement for building large-scale quantum networks.
In 2025, IONQ generated $130 million in revenue, more than tripling their earnings from the previous year. They anticipate revenue between $225 and $245 million in 2026, representing about 81% growth. Analysts maintain a strong positive outlook on the stock, with an average price target of $65.91, suggesting considerable potential for further gains despite recent increases in its value.
Crypto Implications Worth Watching
Advances in fixing errors in quantum computers are making these powerful machines more realistic, which is something the cryptocurrency world has been watching closely. This is because today’s blockchain security, including the encryption used in Bitcoin and most digital wallets, isn’t strong enough to defend against attacks from quantum computers.
The recent NVIDIA Ising launch won’t immediately affect current timelines for quantum computing development. However, any improvements in error correction – which is the main challenge Ising technology addresses – will accelerate the progress towards more stable qubits. Security experts believe this will eventually bring the potential threat to Bitcoin closer to reality, potentially within the next 15 years.
