QuantumScape’s Stock Surges 21% on $990M Trading Volume Surge as Solid-State Battery Demo with Ducati and VW Validates Commercial Potential

, 2025, . The stock’s momentum extended into after-hours trading, reaching $9.68 as the company demonstrated its solid-state battery technology in a real-world application.

The breakthrough came during a high-profile showcase at IAA Mobility in Munich, where QuantumScape and Volkswagen Group’s PowerCo unveiled a modified Ducati V21L race motorcycle powered by the company’s QSE-5 battery cells. This marked the first public deployment of anode-free solid-state batteries in a functional electric vehicle. The demonstration highlighted key metrics, , , . The collaboration with PowerCo and Audi engineers underscored the technology’s readiness for performance testing and commercialization.

QuantumScape’s partnership with PowerCo was further solidified through an expanded licensing agreement, . The funds aim to accelerate prototype production and scale manufacturing via the company’s Cobra separator process. , , .

Analysts view the demonstration as a pivotal step in transitioning the company’s technology from laboratory testing to real-world integration. The collaboration with industry leaders like Volkswagen and Ducati reinforces confidence in QuantumScape’s ability to meet industry demands for superior energy density, safety, and cost efficiency. However, challenges remain, including scaling production and securing OEM contracts amid competition from legacy lithium-ion and other solid-state battery developers.

I’m happy to help you test quantitative ideas, but at the moment the back-testing engine I can run is limited to one security at a time. The strategy you’ve described—“each day buy the top-500 stocks by trading volume, hold for one day, rebalance the next day”—is a cross-sectional portfolio strategy that requires handling hundreds of tickers simultaneously. To proceed, we have two practical options: 1. Narrow the scope to a single stock (or ETF) and back-test a volume-based signal on that individual name. 2. Export the required daily universe data and run the multi-asset simulation in an external portfolio back-test engine (outside this chat), then re-import the equity curve here for analysis. Please let me know which path you’d like to take, or feel free to propose another approach—I’ll gladly set up the appropriate back-test.
