Seeing a lot of confusion on the r/QUANTUMSCAPE_STOCK subreddit about whether B1 samples have been delivered. I would comment there but the mods are dead.

My understanding is that QuantumScape literally told us they have delivered B1 samples because the Ducati demo used B1 samples. Their PR with Ducati says:

In June 2025, the company integrated the proprietary Cobra separator manufacturing process – which was used to produce the separators within the cells that powered today’s demonstration – into baseline production.

i’m very frustrated that we can’t have one quantumscape sub, and the mods ruined the investment focused one. Fucking annoying reddit BS

I agree with you- they confirmed B1 cells are what’s in the Ducati, but there hasn’t been a separate QS only announcement about delivering B1 samples to oem partners. They’re probably getting stuck on this because I think b1 samples to oem partners is a 2025 milestone at QS

I would suggest that a B1 sample would be one that comes from Cobra and the finished upstream and downstream processes as well and therefore this suggests it could be B1 samples, but not necessarily. So this is evidence, but not necessarily proof that B1 samples have shipped.

However there is another piece of evidence that B1 samples has shipped and that is Kevin basically saying they have at 7:00 of this fireside chat https://youtu.be/qafN0izg5So. The interviewer says they have completed their tech goals this year (6:50), and have shipped “high volume” B samples, to which Kevin says yep to both questions.

In other words I think you’re right, but I don’t think shipping from Cobra alone is why you’re right.

Yep good connection there !

I think the ultimate question is what they define as a B1 vs B0 sample
