QuantumScape Stock Is Worth a Closer Look Right Now

This is an exciting time for investors. Emerging technologies, such as artificial intelligence (AI) and electric vehicles (EVs), offer strong investment opportunities in innovative businesses.

One such company is QuantumScape (NASDAQ: QS). It sits at the intersection of AI and EVs, since its solid-state battery technology can provide power for both. The company recently announced the creation of business units dedicated to these two areas, and a third focused on other markets, including aerospace and defense.

After hitting a 52-week high of $19.07 in 2025, the stock fell to a low of $4.77 toward the end of July and has remained near that level. Is this a buy opportunity? Here's a closer look at QuantumScape and whether it's a worthwhile investment.

QuantumScape's opportunities

The energy density, power performance, and safety profile of QuantumScape's solid-state batteries caught the attention of Volkswagen, which has invested hundreds of millions of dollars in the battery maker over the past several years. Volkswagen isn't the only interested party.

QuantumScape announced a multiyear partnership with automotive giant Honda in June. Another major automaker showing confidence in the batteries affirms the strength of the technology. QuantumScape also alluded to working with other major automotive manufacturers, a further sign that its tech is catching on.

Artificial intelligence offers yet another avenue for the company's products. The data centers housing AI systems are increasingly adopting large-scale battery storage architectures pioneered by the electric vehicle industry. This is because AI computing infrastructure is growing in sophistication and size, necessitating so much electricity that EV batteries are now seen as a solution, opening the door for QuantumScape.

QuantumScape's challenges

Before it can capitalize on opportunities in the EV and AI markets, QuantumScape must get its solid-state batteries to a point where mass production is possible. Once it proves it can produce thousands of flawless battery cells quickly and cheaply, it can turn over the manufacturing to its automotive partners.

From there, the company can produce revenue by licensing its design and technology to partners. However, management admitted, "Demonstrating scalable production of a unique technology on a first-of-a-kind automated line is a substantial challenge."

Consequently, the company does not expect to achieve commercialization of its batteries until at least 2029. For now, QuantumScape produces no income and keeps its operations afloat by tapping into its cash stockpile.

Is QuantumScape stock a buy?

The company ended the second quarter with over $800 million in cash, cash equivalents, and marketable securities on its balance sheet. Without revenue coming in, it strives to stretch its cash hoard to reach the 2029 commercialization milestone.

Whether the battery maker has enough funds is questionable. It projects 2026's full-year adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) loss will be between $250 million and $275 million. Its 2025 adjusted EBITDA loss was $252.3 million. Cost-cutting efforts enabled it to reduce its 2026 full-year capital expenditure guidance to between $27 million and $37 million.

Given these numbers, QuantumScape is skating on thin ice. It would have to execute flawlessly to reach 2029 without requiring additional funding. As a result, investing in QuantumScape stock is only for those comfortable with high risk.

Personally, I would not invest. The company is demonstrating promising technology, but keeping its business afloat without a fresh infusion of cash looks like a challenge right now.
