SpaceX IPO Key window: Elon Musk's birthday (June 28, turning 55) + the rare astronomical event 'Venus conjunct Jupiter' (occurring June 8-9, first time in over three years), possibly even accompanied by a planetary alignment. Musk himself suggested choosing this 'auspicious date.' Preparation progress: The earliest possibility is confidentially submitting an IPO registration draft to the U.S. SEC by March 2026. If everything goes smoothly, it could go public in June.
