Lockup & Holding Period Structure
The S-1 reveals a sophisticated lockup structure with significant early-release provisions — this is critical for current and prospective shareholders.
Base Lockup
180 days post-IPO (standard cliff), but with multiple early-release windows. Elon Musk is excluded from all accelerated releases — locked the full 180 days.
Unlock Schedule
| Trigger | Shares Released | Cumulative |
|---|---|---|
| Q2 2026 Earnings (first public quarter) | Up to 20% of eligible shares | ~20% |
| Q2 Earnings + SPCX ≥30% above IPO price | Additional 10% released | ~30% |
| Day 70 post-IPO | 7% of eligible shares | ~37% |
| Day 90 | 7% | ~44% |
| Day 105 | 7% | ~51% |
| Day 120 | 7% | ~58% |
| Day 135 | 7% | ~65% |
| Q3 2026 Earnings | Additional 28% | ~93% |
| Day 180 | All remaining shares | 100% |
Estimated full-release date: Mid-to-late December 2026 (assuming June 2026 IPO pricing).
Key Implications for Holders
- Q2 earnings is the marquee liquidity event — 20–30% of eligible shares could unlock depending on price performance
- The 30% price hurdle creates an embedded incentive for early holders to support the stock through the Q2 print
- By Q3 earnings, cumulative unlock can reach ~90%+; Day 180 becomes a cleanup rather than a cliff
- Public float at IPO expected to be <5% (vs. 20%+ typical for large caps), with up to 30% of float earmarked for retail — expect elevated volatility around each unlock date
- Secondary buyers today at ~$1.25T valuation are subject to the same lockup framework — no time-based discount remains pre-IPO
Note: "Eligible shares" definition and exact treatment of pre-IPO secondary holders vs. direct employees/founders is detailed in the Underwriting section of the S-1 (page 264). We recommend confirming specifics before making any decisions.
