Why QuantumScape Stock Got Crushed in November

2025 has been a good year for QuantumScape (NYSE: QS) stock. Shares have soared about 140% as the electric vehicle (EV) battery company has made progress with its next-generation solid-state technology.

The stock had been doing much better before November, though. The stock is now over 30% off its recent highs, following a 33.4% drop in November, according to data provided by S&P Global Market Intelligence.

An electric vehicle game changer

EV sales growth has slowed after the initial surge of early adopters converted from internal combustion engine (ICE) cars and trucks. Hybrid options have also eroded some interest in the fully electric model offerings. One reason for this is the convenience and reassurance that a backup engine provides, eliminating the risk of running out of battery charge when no charging options are readily available.

If successfully commercialized, QuantumScape's battery technology will lead to safer, faster-charging, and more efficient EV batteries. That could drive a resurgence in demand for battery electric vehicles. In September, the company provided its first live demonstration using a Ducati motorcycle equipped with its battery cells.

QuantumScape followed that with the first of two new partnership agreements for high-volume production and commercialization. That progress led investors to buy QuantumScape stock in droves. Shares more than doubled in September and October.

What's next for QuantumScape?

November acted as somewhat of a "sell the news" month after that sharp run in QuantumScape stock. Nothing specific to the business drove the downturn. Some investors may have decided to lock in their profits, while others may have simply deemed the stock too risky for them.

Investing in QuantumScape takes a certain amount of patience and risk tolerance. Its progress to date makes it seem more likely that the company will be able to produce battery cells at the required high volumes. But competition or new technologies could also impact potential demand.

QuantumScape remains a highly risky and speculative stock. The company is well-positioned to go to market, though. It ended Q3 with about $1 billion in liquidity, which it believes will now carry it through 2029.

Investors who want to own some for the potential success of its solid-state battery technology would be wise to allocate only a speculative amount. Even with the November sell-off, the company is valued at a market cap of about $7.5 billion. That's a good amount of successful sales already built in, even before the company has begun to generate any real revenue.
