Quantum computer stocks rise across the US market, government support boosts buying

In late October 2025, quantum computer-related stocks were bought en masse in the US futures market, with multiple companies recording double-digit gains. Buying pressure increased even during pre-market trading, highlighting high expectations for the entire industry. Coupled with the US government’s industry support initiatives, the quantum computing sector is attracting attention as the next tech trend.

Pre-market buying spree, multiple stocks rise by double digits

Before the market opened, the stock prices of several quantum computing companies surged significantly. IONQ (IONQ.N) rose by 13%, RIGETTI (RGTI.O) by 12%, D-Wave (QBTS.N) by 16%, and Quantum Computing Inc. (QUBT.O) by 13%, demonstrating strong trading activity across the board. Notably, D-Wave’s 16% increase is a remarkable growth rate within the industry.

These companies are central to the US quantum computer industry, and the concentrated buying during pre-market trading suggests a strong confidence among institutional and individual investors in the industry’s prospects.

Industry-wide boom driven by federal funding support

The increased buying pressure on quantum computing stocks is driven by active industry support from the US government. Deputy Secretary of Commerce Paul Dabbar is leading negotiations, working with companies such as IonQ, D-Wave, Quantum Computing Inc., and Atom Computing to exchange stocks for federal funding.

Government funding is expected to accelerate R&D efforts and promote overall market growth. This has led to a positive investor sentiment and positioned the US quantum computing industry as a strategically important sector at the national level.

Google’s quantum chip “Willow” achieves new milestone

Further boosting industry enthusiasm, Google announced a major technological breakthrough. The company revealed that its quantum chip “Willow” completed quantum chaos simulation calculations in just two hours, marking a significant step toward practical quantum computing.

This technological breakthrough suggests the potential to perform computational tasks that are impossible for traditional supercomputers within a short time. The achievement by a major tech company has increased investment appeal in quantum-related stocks and improved overall market sentiment.

Meanwhile, Tesla declines due to profit reduction

Contrasting with the positive mood surrounding quantum computing stocks, Tesla (TSLA.O) fell 3.3% in pre-market trading after its third-quarter profits significantly declined. The overall US stock market is showing divergence in buying and selling pressures among stocks, influenced by their earnings performance.
