SpaceX is rewriting the record books for private company growth. In the unlisted “grey market” and private secondary sales, the company’s valuation has undergone a meteoric rise, surging toward an unprecedented $1.75 trillion as it prepares for what is expected to be the largest Initial Public Offering (IPO) in history this June.
While “300%” refers to the cumulative growth over the last 18–24 months, the most recent jump is driven by a unique “Space + AI” narrative following the acquisition of xAI.
1. The Valuation Trajectory (2024–2026)
The surge in the unlisted market has been relentless, fueled by the profitability of Starlink and the successful operational milestones of Starship.
| Date | Event | Share Price (Est.) | Valuation |
| June 2024 | Secondary Sale | ~$210 | $210 Billion |
| Dec 2025 | Tender Offer | $421 | $800 Billion |
| Feb 2026 | xAI Acquisition | $526 | $1.25 Trillion |
| April 2026 | Pre-IPO Grey Market | ~$615 | $1.75 Trillion |
Note: The “300% surge” represents the jump from the $400B valuation in mid-2025 to the current $1.75T IPO target—a nearly 4x increase in less than a year.
2. The Catalyst: The xAI Merger
In February 2026, SpaceX completed an all-stock acquisition of Elon Musk’s xAI. This transformed the market’s perception of SpaceX from a “rocket company” to a “space infrastructure monopolist.”
- Orbital Data Centers: SpaceX is now leveraging Starlink to host AI compute in orbit, bypassing the cooling and power constraints of terrestrial data centers.
- The “Grok” Integration: xAI’s large language models are being integrated into Starlink’s autonomous fleet management and Starshield military applications.
3. The Historic June 2026 IPO
SpaceX has reportedly filed for its IPO, with a roadshow set to begin the week of June 8, 2026. The offering is designed to be unlike any other in Wall Street history.
- Retail Revolution: In a move to “democratize” the upside, SpaceX is reportedly planning to allocate up to 30% of its shares to retail investors via platforms like Robinhood. This is triple the usual 10% allocation.
- Fundraising Target: The company aims to raise between $40 billion and $75 billion in new capital.
- S&P 500 Fast-Track: S&P Dow Jones Indices is reportedly considering rule changes to allow SpaceX to enter the S&P 500 almost immediately after listing, rather than waiting for the standard seasoning period.
4. Risks: Fundamentals vs. Hype
Despite the excitement, many institutional analysts are sounding alarms over the “priced for perfection” valuation.
- The P/S Multiple: At a $1.75 trillion valuation and projected 2026 revenue of $20 billion, SpaceX is trading at a price-to-sales (P/S) ratio of nearly 90x.
- The “Front-Running” War: Insiders suggest the timing of the IPO is a strategic move to “siphon” capital away from rivals like OpenAI (recently valued at $852 billion) and Anthropic.
5. How to Access Unlisted Shares
For most people, direct access to SpaceX before June remains restricted to Accredited Investors (net worth >$1M or annual income >$200k).
- Secondary Platforms: Brokers like UpMarket and Forge Global facilitate trades for qualified individuals, often with minimum investments of $50,000.
- The “Proxy” Trade: Many retail traders are currently buying “proxy stocks” with high correlation to SpaceX, such as EchoStar (SATS) or Lockheed Martin (LMT), to play the pre-IPO momentum.
