The SpaceX IPO and the trillionaire math
The single most important event for Musk's trillionaire crossing is the SpaceX public listing. This is the math on what happens at each pricing scenario.
Is Elon Musk a trillionaire yet?

Filing & timing
On April 1, 2026, multiple outlets reported that SpaceX confidentially submitted a Form S-1 to the SEC. The confidential-submission process under the JOBS Act lets emerging growth companies start the SEC review without making the document public. The S-1 only becomes public 15 days before the road show begins. The widely reported target date for the public listing is June 28, 2026— Musk's 55th birthday — at a target valuation of $1.5–2 trillion.
Stake math
Public reporting and prior tender-offer disclosures put Musk's economic ownership of SpaceX at approximately 42.5%. He also holds Class B super-voting shares that give him outright voting control even after dilution from the IPO. The table below shows what his stake is worth at each valuation scenario.
| SpaceX valuation | Musk stake (42.5%) | Marked w/ 5% disc. | If listed (no disc.) |
|---|---|---|---|
| $1.0T | $425B | $404B | $425B |
| $1.25T (current) | $531B | $505B | $531B |
| $1.5T | $638B | $606B | $638B |
| $1.75T (consensus) | $744B | $707B | $744B |
| $2.0T | $850B | $808B | $850B |
Why the IPO closes the trillionaire gap by itself
At a $1.75T listing, the SpaceX stake alone is worth $744B without the discount. Add Tesla direct shares + the 2018 options at intrinsic value (typically $300–450B combined depending on TSLA price), plus $43B for other holdings, and Musk's net worth lands between $1.05T and $1.20T — comfortably above the trillion-dollar threshold for the first time.
What we change in the live tracker if SpaceX prices
On the IPO day, two things change in our calculation:
- The SpaceX valuation input switches from the private-tender mark ($1.25T) to the public market cap.
- The 5% illiquidity discount goes to zero — listed shares are liquid.
