YC's top companies represent just ~5% of the total number of portfolio companies, yet they account for the vast majority of the total value.

These top companies have valuations that follow a steep power-law curve, with just 3 companies, Airbnb, DoorDash, and Stripe, representing more than half of YC's top companies portfolio value.

The top 10 companies represent ~75% of YC's top companies portfolio value, and every one of them is a 'unicorn' valued at $1B+.

Most of these top startups raised seed rounds at $3M to $10M valuations, so a median top company with a ~$500M valuation is now valued at a whopping 50x to 150x its seed stage valuation.

For Airbnb, the valuation growth is even more staggering, at around 3000x its seed stage valuation, thanks to its ~$100B valuation.

This massive potential upside is a key takeaway for seed stage investors, who should be swinging for the fences since a few mega successes drive the vast majority of YC's portfolio value.
