QuantumScape Is Down 96% From Its High. Is 2027 Finally the Solid-State Battery Year?

QuantumScape's stock has plummeted 96% from its all-time high as the solid-state battery developer has failed to commercialize any batteries or generate meaningful revenue despite earlier promises. The company now expects commercial readiness not until 2029 and faces intensifying competition from other automakers and startups. With a $3.4 billion valuation but no revenue, the outlook remains murky.
