QS stock retreats as QuantumScape faces cautious analyst outlook

QS stock has fallen sharply in 2026 as QuantumScape continues to burn cash and analysts see limited upside despite solid-state battery progress and a wide gap between current price and average targets.

QS stock, representing QuantumScape Corporation (ISIN US7491621036), is trading at 5.59 USD as of August 31, 2026, down 46.4% from 10.42 USD at the start of 2026 according to MarketBeat data updated September 1, 2026.

Stock suffers 2026 drawdown

According to MarketBeat, QuantumScape shares closed at 5.59 USD on August 31, 2026, implying a market capitalization of 3.46 billion USD and leaving the stock within a 52 week range between 4.77 USD and 19.07 USD as of September 1, 2026.

Measured from a level of 10.42 USD at the beginning of 2026 to 5.59 USD at the end of August 2026, QS stock has declined by 46.4 percent in the year to date period, highlighting the volatility investors face in solid state battery names.

Analysts stay cautious on valuation

MarketBeat reports that QuantumScape has a consensus analyst rating of Reduce with an average price target of 9.47 USD, implying about 69.4 percent upside from the current price of 5.59 USD as of September 1, 2026, and a target range between 6.00 USD and 12.00 USD.

Based on MarketBeat figures, QuantumScape trades at roughly 2.62 times its book value of 2.13 USD per share, while carrying a negative trailing twelve month earnings per share of minus 0.67 USD and a net loss of 477.86 million USD in the most recent fiscal period.

Solid state battery program remains pre revenue

QuantumScape is described by MarketBeat as a development stage company focused on solid state lithium metal batteries for electric vehicles, with its core technology based on a solid ceramic separator intended to deliver higher energy density, faster charging and improved safety versus conventional lithium ion cells.

The company remains pre revenue according to the same overview, with annual sales reported as not available and valuation metrics such as price to sales therefore not meaningful, while its cash position and low debt level are reflected in a debt to equity ratio of 0.02 and a very high current ratio of 21.14 as of the latest reported balance sheet.

QS stock price snapshot and investor view

As of August 31, 2026, QS stock is listed on the New York Stock Exchange in USD and trades with a 52 week range between 4.77 USD and 19.07 USD per MarketBeat, underscoring how far the share price currently sits below its recent high.

For investors, the combination of a 46.4 percent year to date decline, a consensus Reduce rating and a significant gap between current price and average analyst target illustrates both the perceived execution risks and the potential reward if QuantumScape can eventually commercialize its solid state battery technology.
