Investing in SpaceX if Elon Musk Becomes the First Trillionaire
Question: Should I invest in SpaceX if Musk becomes the first trillionaire?
Prepared by the ChoiceScore Research Desk · Editor-approved for the curated library · Reviewed September 3, 2026
Direct answer
Based on the modest expected upside, high failure risk, and limited ownership stake, investing $10,000 in SpaceX at a $200 billion valuation is not strongly recommended for most individual investors.
Summary
SpaceX is valued at roughly $200 billion today, and a $10,000 investment would buy an infinitesimal 0.000005 % stake. Assuming a 30 % chance of catastrophic failure and a future valuation of $300 billion, the expected monetary return is about $10,500 – a 5 % gain over the original capital. This return is well below the historical 7 % annual return of diversified equity markets, and the breakeven valuation needed to simply recover the $10,000 would be about $286 billion. Consequently, the risk‑adjusted case for a small private investment in SpaceX is weak, especially given the illiquidity of a pre‑IPO private share.
Choice Score breakdown
- Expected Return 60/100 — Modest upside relative to risk.
- Risk Level 40/100 — High probability of failure for a single launch‑focused venture.
- Liquidity 30/100 — Private shares cannot be sold until an IPO or secondary market emerges.
Best for / Not best for
Best for
- High‑net‑worth individuals comfortable with speculative, illiquid assets
- Investors who want exposure to the space sector and can afford to lose the entire stake
Not best for
- Conservative investors
- Those who need liquidity within 5‑10 years
- Investors without access to secondary markets for private shares
Scenarios
- Optimistic (25% likely)
SpaceX successfully launches Starship, expands Starlink to 5 billion users, and achieves a $350 billion valuation within 5 years. The probability of failure drops to 10 % due to proven technology. - Likely (55% likely)
SpaceX continues its current trajectory, reaches a $300 billion valuation, but experiences occasional launch setbacks that keep the failure probability at 30 %. - Pessimistic (20% likely)
Regulatory hurdles, a major launch accident, or a slowdown in Starlink subscriptions cap the valuation at $250 billion and raise the failure probability to 50 %.
Calculations
| Metric | Result | Formula |
|---|---|---|
| Ownership Percentage | 0.000005 % of SpaceX | stake × 100 |
| Expected Monetary Value (EV) | $10,500 | (future_valuation × stake) × (1 − probability_of_failure) |
| Breakeven Valuation | $285,714,285,714 (≈ $286 billion) | investment ÷ (stake × (1 − probability_of_failure)) |
| Potential Upside Percentage | 5 % upside | ((EV − investment) ÷ investment) × 100 |
| Opportunity Cost vs. S&P 500 | $3,525 lost relative to a diversified index fund | Future value of $10,000 at 7 % annual return for 5 years − EV |
Pros & cons
Pros
- Potential for massive upside if SpaceX achieves a $350 billion valuation.
- Exposure to a high‑growth sector (space launch, satellite internet, interplanetary travel).
- Alignment with Elon Musk’s brand and long‑term vision, which can attract future capital.
Cons
- Extremely small ownership stake makes any gain negligible in absolute dollars.
- High probability of failure (≈30 %) due to technical, regulatory, and market risks.
- Illiquid private share; cannot be sold until an IPO or secondary market appears.
Assumptions
- Current Valuation: $200 billion — Based on publicly reported estimates from recent news articles.
- Future Valuation: $300 billion — A mid‑range projection assuming continued growth of Starlink and Starship programs.
- Probability of Failure: 30 % — Industry analysts cite a 20‑40 % risk of a major setback for high‑tempo launch companies.
- Investment Amount: $10,000 — User‑provided figure for a single private placement.
- Stake Fraction: 5 × 10⁻⁸ — Derived from dividing the $10,000 investment by the $200 billion valuation.
- S&P 500 Historical Return: 7 % per year — Long‑term average return used for opportunity‑cost comparison.
Practical next steps
- 1. Verify the exact terms of the private placement (share class, voting rights, conversion provisions).
- 2. Model multiple valuation scenarios (optimistic, likely, pessimistic) using the formulas above.
- 3. Compare the expected return to a benchmark (e.g., S&P 500) and calculate opportunity cost.
- 4. Assess personal risk tolerance, liquidity needs, and investment horizon.
- 5. Decide whether to allocate a small speculative portion of your portfolio or to seek diversified alternatives.
Methodology
The analysis combined publicly reported valuation figures (BBC, Business Insider, Wikipedia) with user‑provided financial inputs. Expected monetary value was calculated by weighting the projected future valuation by the user‑specified ownership fraction and adjusting for a 30 % probability of catastrophic failure. Breakeven valuation was derived algebraically to determine the future company worth needed to simply recover the $10,000 outlay. Opportunity cost was estimated using the historical 7 % annual return of the S&P 500 over a five‑year horizon. Scenario modeling incorporated plausible industry risk ranges and growth trajectories. All assumptions are explicitly listed, and sensitivity to key variables is explored through optimistic, likely, and pessimistic cases.

FAQ
- What happens to my investment if SpaceX never goes public?
- Your private shares would remain illiquid; you could only sell them in a secondary market if one emerges, or they may be bought back by the company at a negotiated price, which could be lower than your original outlay.
- How does the 30 % failure probability affect my expected return?
- The probability reduces the expected monetary value because the calculation multiplies the future valuation by (1 − failure probability). With a 30 % chance of total loss, the EV drops from $15,000 (if certain) to $10,500.
- Can I increase my upside by buying more shares?
- Yes, a larger investment raises the absolute stake and thus the expected profit, but it also magnifies the amount at risk. The percentage return and breakeven valuation remain unchanged.
