SpaceX, the aerospace company led by Elon Musk, has reached a valuation of $350 billion following a secondary share sale. The company bought back $1.25 billion worth of stock from insiders at $185 per share, making it the most valuable private startup globally. This valuation surpasses that of major publicly traded companies such as LVMH ($347 billion), Salesforce ($341 billion), and Chevron ($280 billion). According to Bloomberg, over the past decade, SpaceX's valuation has grown significantly, from $10 billion to its current level, reflecting its pivotal role in the aerospace industry. If SpaceX were to go public at this valuation, it would rank as the 24th largest company in the S&P 500.
