For example, if you assume a 15% dilution over 11 fundraising rounds, then it's 0.0167% which is +$1.5MM at a $9B valuation.

at 20%: +730k

at 25%: +$380k

I picked 15% because it seemed a good middle ground. Seed rounds are often <15%, Series A/B is around 20-30%, and later rounds target <5-10%. Because Palantir did so many rounds, I would guess only a few were significantly (> 15%) dilutive.
