Stripe is the second most valuable YC company. Total valuation of all companies that YC funded (more than 1,900) now exceeds 100 billon dollars.

Airbnb has a private valuation of 31 billion. Stripe has a private valuation of 20 billion. Dropbox has a public valuation (DBX) of 11 billion.

So the two most valuable companies account for about half the total value of all the YC companies. This is what a power law looks like!
