- Stock surge: QS shares jumped roughly 20% on Oct. 13 and hit a new 52-week high (around $17.79) [1] [2]. This follows a 200%-plus rally in 2025 as investors cheered recent technology and partnership news.
- New partnerships: QuantumScape announced two major alliances. On Sept. 30 it teamed up with Corning to co-develop high-volume manufacturing of QS’s ceramic battery separators [3]. On Oct. 7 it signed a joint development agreement with Japan’s Murata Manufacturing to scale up production of QS’s ceramic solid-state separators [4]. These deals aim to overcome a key hurdle in mass-producing safe, high-energy solid-state batteries.
- VW/Ducati demo: In September at the IAA Mobility show in Munich, QS and Volkswagen Group’s battery arm PowerCo powered a Ducati electric motorcycle with QS’s latest QSE‑5 solid-state cells [5] [6]. The on-stage demo showcased QS’s technology: the anode-free QSE‑5 cells (made with QS’s Cobra separator process) achieved industry-leading specs (∼844 Wh/L, 10–80% charge in ~12 min, 10C continuous discharge) [7]. This “first live demonstration” of a solid-state battery in a vehicle underscores QS’s progress toward real-world EV use [8] [9].
- VW PowerCo funding: QS also announced that VW’s PowerCo will invest an additional $131 million in milestone payments over two years to speed up QSE‑5 production [10]. CFO Kevin Hettrich noted this funding “will help narrow net losses and strengthen the company’s financial position” [11]. The money extends QS’s cash runway into 2029.
- Upcoming earnings: QuantumScape will report Q3 2025 results on Oct. 22 (after market close), with a live webcast and Q&A scheduled [12]. Management is taking shareholder questions through Oct. 21, highlighting strong investor interest.
- Analyst views: Despite the excitement, QS remains pre-revenue and carries execution risk. Many analysts still rate the stock conservatively (consensus “Hold/Reduce”), with average price targets ($5–$7) far below current levels [13] [14]. As Zacks research noted, only “strong technological advancements, an extended funding runway … and deepening industry partnerships” prevent QS from being just a speculative play [15].
- EV industry context: Solid-state batteries (with solid ceramic electrolytes instead of liquid) are viewed as the next leap for EVs, promising longer range, faster charging and better safety [16] [17]. Major automakers are racing to commercialize this tech – for example, Toyota targets its first solid-state EV by 2027–2028 [18], while Mercedes and others are also testing lithium-metal solid-state packs. QS’s advances (and those of partners like VW) could help EVs overcome range and charging limits, but widespread use is still years away.
QuantumScape is a Silicon Valley startup developing solid-state lithium-metal batteries for electric vehicles. Unlike conventional Li-ion packs with liquid electrolytes, QS’s batteries use a solid ceramic separator and a pure lithium-metal anode. This design boosts energy density and charging speed while reducing fire risk [19] [20]. Investors bet that QS’s tech could give EVs longer range and simpler packaging.
In late September and early October, QS delivered on that promise with major announcements. On Sept. 30 it revealed a joint agreement with Corning, Inc. (maker of specialty glass and ceramics) to co-develop manufacturing for QS’s ceramic separators [21]. Corning’s ceramics expertise will help QS scale up “high-volume production” of these separators for commercial batteries [22]. QS CEO Siva Sivaram praised the partnership, noting “Corning’s world-class capabilities in ceramics manufacturing make it an ideal addition to the QS technology ecosystem” [23]. Similarly, on Oct. 7 QS and Murata Manufacturing (a Japanese electronics giant) formalized a joint-development deal for QS’s ceramic separators [24]. Murata has long-discussed collaboration since early 2025, and now will apply its ceramics material and firing expertise to scale production of QS’s separators [25]. Murata’s president Norio Nakajima said the companies will move QS’s technology “to a new stage… leveraging [Murata’s] strengths in ceramics technology” [26], and Sivaram added that “partnership with Murata is an important part of building a robust global ecosystem of suppliers” for commercial solid-state batteries [27].
These manufacturing partnerships came hot on the heels of a live battery demo that captured headlines. At the IAA Mobility show in Munich (Sept. 2025), VW Group’s PowerCo and QS unveiled a Ducati V21L race motorcycle powered entirely by QS’s latest QSE‑5 solid-state cells [28]. This was billed as the world’s first live demonstration of an EV (a motorcycle) running on solid-state lithium-metal batteries. The cells were built using QS’s new “Cobra” process (integrated into production earlier in 2025), which greatly boosts output. In the race setting they delivered roughly 844 Wh/L energy density and could charge from 10% to 80% in just about 12 minutes, all while sustaining a 10C discharge rate [29]. These record-setting numbers illustrate why QS claims its batteries could massively extend EV range and slash charge times. As CEO Siva Sivaram said at the demo: “Today we’ve crossed the threshold from possibility to reality… Our world-leading battery innovation, combined with Ducati’s craftsmanship and performance focus, will help usher in a new era of electrified transportation” [30]. VW’s PowerCo CEO Frank Blome echoed that sentiment, calling solid-state batteries a “game-changing” technology that will “redefine what’s possible” for high-performance EVs [31].
The Ducati demo and new partnerships have pushed QS closer to commercialization. VW’s PowerCo (backed by VW, Audi, BMW) also expanded its alliance with QS in mid-2025, pledging another $131 million in milestone payments to bring QSE‑5 production online [32]. Under this agreement, QS will prioritize producing QSE‑5 prototype cells in its San Jose pilot line for PowerCo, accelerating the path to mass production. (PowerCo has rights to license QS’s tech and plans to eventually manufacture gigawatt-hours of these batteries at scale.) In the demo press conference, Thomas Schmall (VW Components CEO) highlighted that the Ducati test will stress QS’s cells in a real-world, high-performance application. As Reuters reported in 2024, VW’s PowerCo license lets VW produce up to 40–80 GWh per year of QS batteries – enough for roughly a million EVs annually [33].
The market reaction: All this news lit a fuse under the stock. QS shares spiked about 16–20% on Oct. 13, continuing an explosive rally. On Oct. 14 the stock briefly traded as high as $17.79 (closing $17.02) – a fresh 52-week peak [34]. Trading volume was heavy as momentum traders and investors piled in. Year-to-date the stock has more than doubled in 2025 (earlier in October it was ~$7–9) [35] [36]. MarketBeat noted analysts are now watching closely, though ratings remain mixed: the consensus is still a “Reduce/Hold” with an average target around $5.88 [37] [38] (reflecting the huge gap between current price and fundamentals). Insider trading filings show some executive selling ($5.8M sold at ~$11 in July) [39], adding caution.
Expert take and outlook: Industry analysts say QS’s latest moves have “de-risked” its technology path. Zacks Research writes that the mix of “strong technological advancements, an extended funding runway through 2029 and deepening industry partnerships – notably with Volkswagen and Corning – adds substance to its long-term story” [40]. QS executives themselves stress the same point: CFO Hettrich noted the additional VW funding will “strengthen the company’s financial position” as it scales up (even as losses narrow) [41]. At the same time, experts caution that QS is still years from volume production and profits. The company last quarter lost $0.20 per share on only $36.7M revenue (mostly from government grants), so current valuation relies on faith in future breakthroughs [42].
The broader EV landscape underscores both promise and competition. Major automakers worldwide are betting on solid-state batteries to overcome EV limits [43] [44]. For example, Toyota just announced plans to launch an all-solid-state EV around 2027–2028, having secured partnerships to develop next-gen cathode and electrolyte materials [45]. Mercedes-Benz claims it already drove ~750 miles on a solid-state-equipped EV last year. Meanwhile, companies like CATL and BYD in Asia are also investing heavily. QS’s demonstration and supply deals put it at the center of this race: if its tech delivers on its hype, it could enable EVs with longer ranges, faster charge times and lower fire risk than today’s batteries. As one analyst summed up, solid-state batteries “hold more energy than current liquid batteries” and are expected to “speed [the] transition to EVs” by solving range anxiety [46].
Bottom line: QuantumScape’s latest news – from its Ducati motorcycle demo to Corning and Murata partnerships – has ignited investor optimism. The stock’s recent highs reflect that excitement. However, industry veterans warn that solid-state batteries still face technical and scaling challenges. QuantumScape must now execute its pilot production, deliver on Q3 progress (Oct. 22), and eventually win OEM contracts beyond VW. If it succeeds, the company could help usher in a new generation of EVs with much better batteries. But for now, the story remains one of potential: leading partnerships and lab success has driven the stock rally, even as analysts remind investors that “any delays en route to commercializing its batteries could be devastating” to QS’s lofty valuation [47].
