Shares of QuantumScape (QS) stock climbed as high as 14% Thursday following the company’s disclosure of a multi-year collaborative research partnership with Honda R&D Co., a division of Honda Motor. Trading activity saw the stock fluctuating between approximately $7.38 and $8.02 throughout the session.
The collaboration focuses on developing QuantumScape’s solid-state lithium-metal battery architecture. This joint initiative encompasses a multi-year roadmap addressing both technological advancement and production methodology.
The partnership’s origin story is particularly noteworthy. Honda conducted extensive due diligence before committing, executing comprehensive technical assessments and comparative analysis against competing battery technologies in the market.
Atsushi Ogawa, Chief Operating Officer at Honda’s Research Center of Excellence, stated that QS technology “demonstrated compelling and unique advantages during our evaluation.” He further noted Honda’s belief in the “potential for QS technology to add value across a range of applications, including automotive.”
Unlike traditional lithium-ion batteries that rely on liquid electrolytes, solid-state batteries offer enhanced driving range, accelerated charging capabilities, superior safety profiles, and reduced manufacturing costs for electric vehicles — though commercial-scale production remains on the horizon.
Expanding Automotive Partnerships
The Honda collaboration extends QuantumScape’s reach within the global automotive industry. The battery developer maintains an existing relationship with Volkswagen via its PowerCo division. Securing Honda adds another major global automaker to QS’s partnership portfolio.
QuantumScape faces competition in the solid-state battery sector from firms such as Solid Power and SES AI. The Honda partnership, validated through rigorous independent testing, strengthens QS’s competitive standing in this emerging market segment.
This announcement coincides with QuantumScape achieving meaningful operational milestones. Recent company reports indicate reduced net losses, progress on Eagle Line manufacturing capabilities, and initial customer invoicing — all indicators of advancing commercialization efforts.
Market Performance Analysis
Despite Thursday’s rally, QS stock remains approximately 30% lower in 2026. The electric vehicle supply chain sector has experienced headwinds following the September 2025 expiration of federal EV tax incentives.
Current trading levels sit significantly below the 52-week peak of $19.07. Thursday’s session saw prices ranging from $7.14 to $8.02.
Looking at the trailing twelve-month period, QS has appreciated roughly 66%, representing a substantial rebound from previous lows during that timeframe.
Honda’s American depositary receipts advanced approximately 0.7% Thursday but continue trading down roughly 11% in 2026 and 11% over the past year.
Broader equity markets showed strength Thursday. The S&P 500 advanced approximately 0.8% while the Dow Jones Industrial Average posted gains near 0.5%, as market participants focused beyond the Federal Reserve’s recent indication that rate increases remain possible in 2026.
Initial jobless claims registered 226,000 for the week concluded June 13, declining 4,000 from the previous week’s figure.
QuantumScape disclosed its Honda R&D partnership on June 18, 2026, from its San Jose, California headquarters.
