Short sellers boost bets against SpaceX and it's already costing them

Short sellers have built positions equal to nearly one-third of SpaceX’s tradable shares, but the decline bet has already resulted in roughly $750M of paper losses. Despite ongoing bearish positioning, the magnitude of losses suggests the stock’s post-debut decline thesis is not playing out as expected. The short-covering/positioning dynamic could meaningfully influence sentiment and near-term trading behavior.
