NVIDIA Stock Rises 2.9% as AI Infrastructure and Quantum Shares Rally

Date: August 3, 2026

Key Takeaways

• NVIDIA shares reached an intraday high of $208.69 before closing 2.9% higher at $206.64.
• Lumentum surged 9.2% as investors focused on the optical networking company’s 90% year-over-year quarterly revenue growth.
• D-Wave gained 10.5% following a Nasdaq Verafin agreement, while IonQ rose 6.6% after completing its acquisition of SkyWater Technology.

NVIDIA Stock Climbs as AI Infrastructure Demand Remains in Focus

NVIDIA stock advanced on August 3, driven by improved risk appetite and ongoing investments in artificial intelligence (AI) infrastructure, which supported technology shares. The chipmaker's stock climbed to an intraday high of $208.69, representing a gain of nearly 4%, before closing 2.9% higher at $206.64, up from the previous session's close of $200.75.

Investor sentiment was bolstered by expectations that cloud providers, enterprises, and governments will continue to increase spending on AI computing capacity. Notable projects include a proposed partnership between NVIDIA, NAVER, and Brookfield to expand an AI factory in South Korea from 55 megawatts to 200 megawatts by 2028.

Despite these developments, NVIDIA shares have hovered around the $200 mark in recent months, even as major technology companies forecast higher capital expenditures. Investors are keenly awaiting NVIDIA’s earnings report on August 26 for indications that infrastructure spending is translating into stronger shipments of accelerators and revenue growth.

Lumentum Surges as AI Demand Supports Optical Networking

Lumentum Holdings saw its shares close 9.2% higher at $779.89, outperforming the broader semiconductor sector. The company, which supplies lasers, optical components, and networking systems for AI servers and data centers, reported a remarkable 90.1% year-over-year increase in fiscal third-quarter revenue, reaching a record $808.4 million. Component revenue rose by 77.3%, while systems revenue surged by 121.1%.

Looking ahead, Lumentum has guided for fiscal fourth-quarter revenue between $960 million and $1.01 billion, with a non-GAAP operating margin of 35%–36%.

D-Wave Rallies on Nasdaq Verafin Agreement

D-Wave Quantum shares finished 10.5% higher at $19.98 after gaining around 11% during the session. The company announced a collaboration with Nasdaq Verafin to explore whether quantum computing can enhance financial crime detection. This partnership will start with a proof-of-concept utilizing D-Wave’s quantum-annealing technology to analyze account activity and transaction patterns.

The initial project aims to assess hundreds of potential data signals to determine if quantum-hybrid machine-learning systems can identify unusual behaviors linked to fraud and money laundering. The agreement is still in its early stages, and while it may expand into pilot applications, no commercial contract value or guaranteed revenue has been disclosed.

IonQ Gains After Completing SkyWater Acquisition

IonQ shares rose approximately 10% during the session before closing 6.6% higher at $38.85, following the completion of its $1.8 billion acquisition of SkyWater Technology. Under the terms of the deal, SkyWater shareholders received $15 in cash and 0.4883 IonQ shares for each SkyWater share. SkyWater will continue to operate under its existing name as a subsidiary of IonQ.

This acquisition provides IonQ with direct access to US-based semiconductor fabrication and advanced manufacturing capabilities, which are crucial for its goal of developing a vertically integrated quantum technology platform. Investors will now evaluate whether this combination can expedite IonQ’s fault-tolerant quantum computing roadmap while managing integration costs and operational complexities.

What Could Drive AI and Quantum Stocks Next?

The rally in these stocks coincided with broader gains in US equities, as easing tensions in the Middle East and lower oil prices encouraged demand for risk-sensitive assets. Near-term attention will shift to upcoming corporate results, with IonQ set to report on August 5, followed by D-Wave on August 6, and NVIDIA on August 26.

For NVIDIA and Lumentum, the key question is whether the increased AI capital expenditure will continue to drive higher sales of chips and optical components. For D-Wave and IonQ, investors will focus on the commercial adoption of their technologies, the execution of acquisitions, and the conversion of technology partnerships into recurring revenue. Given their valuations are highly sensitive to growth expectations, earnings guidance, and market sentiment, these stocks may experience continued volatility.
