Austin Lieberman expresses a bearish sentiment toward SpaceX, suggesting it is overvalued at a $2T valuation given its $19B in revenue and $5B net loss. Conversely, Polymarket traders are pricing a potential SpaceX IPO closing market cap at $2.17T, which would imply a 23% "day 1 pop" for the asset. Visual data from Polymarket shows a 67% probability of the company's IPO closing market cap exceeding $2T.
