Quantumscape Corporation
A developer of next-generation solid-state lithium-metal batteries for electric vehicles, QuantumScape replaces the liquid electrolyte found in conventional lithium-ion cells with a proprietary solid ceramic separator, aiming for longer range, faster charging, and safer packs. The company was founded in 2010 by Jagdeep Singh, Dr. Tim Holme, and Stanford professor Fritz Prinz as a spin-out from Stanford research, and it counts Volkswagen among its earliest partners. Its name blends "quantum" (a nod to a transformative leap) with "scape," evoking a new landscape of energy storage.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -16.35M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
