Methodology & status definitions
How each row is labelled and calculated.
Closed round
A round announced by OpenSea, bringing new money to the company.
Valuation ÷ run-rate
Post-money valuation ÷ the run-rate the company stated in that announcement (GNF calc.). OpenSea stated no run-rate with a round, so no multiple is shown.
What is not a separate row
Seed funding before 2021, investor fund marks, the SEA token (OpenSea Foundation, not equity), token valuations or prediction-market prices, and secondary-market share prices.
