Real Polymarket history from listing to today. This is the raw crowd layer: the de-vigged, conditional-on-IPO expected valuation. The live Mecone index anchors this layer to the last funding round and glides it with the crowd's IPO timing, so the published index on markets.mecone.trade differs from the raw crowd mean shown here by construction.
