SpaceX Valuation Surpasses Amazon and Microsoft on Third Trading Day

Shares of SpaceX jumped 20% on Monday, June 16, 2026, in its third day of trading as a public company. The massive gain pushed the company's market capitalization above $2 trillion, overtaking tech giants Amazon (AMZN) and Microsoft (MSFT). This is the second-largest one-day gain in market value for a U.S. company in history.

Possible Reasons

No official statement from the company has been released explaining the sharp rise, but analysts point to several potential factors:

• Optimistic expectations about SpaceX's AI business, as the company has unique capabilities in satellite-based cloud computing (Starlink) that could serve as a platform for AI applications.
• Announcement of new government contracts, possibly with NASA or the U.S. Department of Defense, boosting future revenue streams.
• Momentum from retail and institutional investors eager to acquire shares early in the company's public life.

Context

The surge comes just three days after SpaceX's stock market debut, which has seen volatile trading since day one. Before the jump, the company's market cap was around $1.7 trillion. The largest one-day gain in market value for a U.S. company remains NVIDIA (NVDA) in February 2024, when it added $277 billion in a single day.

Similar Moves in the Sector

Other major tech stocks did not see similar moves on Monday. While Amazon and Microsoft rose slightly, NVIDIA, Apple (AAPL), and Alphabet (GOOGL) remained relatively flat. This suggests the move was specific to SpaceX and not part of a broader sector trend.
