SpaceX (SPCX) surpassed Tesla (TSLA) as the most valuable company in Elon Musk‘s portfolio following its historic initial public offering (IPO) on Friday. In fact, the rocket manufacturer became the sixth most valuable U.S.-listed company. After opening at $150 a share, the stock closed over 19% higher on the first day of trading, pushing SpaceX’s market cap above $2 trillion, higher than Tesla’s $1.3 trillion.Introducing TipRanks MCP for Agents Deliver institutional-grade market data directly into Claude, ChatGPT, Cursor, and other MCP-compatible AI tools.

Tesla remains a major force in electric vehicles and energy storage, but its valuation has cooled as competition rises and growth slows. SpaceX, meanwhile, is seen as early in its commercial expansion, with Starlink, deep‑space missions, and government contracts all driving optimism.
Only Apple (AAPL), Microsoft (MSFT), Alphabet (GOOGL), Amazon (AMZN), and Nvidia (NVDA) sit above it, giants that took decades to reach similar heights. For SpaceX to join that group on day one reflects both the scale of its business and the market’s belief that the next decade of growth in Musk’s portfolio may come from space, not cars.
