Musk SpaceX IPO threshold engine - corrected calibration
A stylized compartment model of the SpaceX IPO trading window using the Business Insider calibration: Musk's net worth was about $971bn at the IPO price, so the immediate trillionaire threshold was a $29bn recognized-upside gap. The model tracks a $200bn upside pool moving through market repricing, durable threshold cushion, and volatility drag.
