Additional Release Shares (price trigger)
The one price-contingent unlock (+10% of the 180-day cohort) fires only if Class A close ≥ $175.50 for 5 of 10 trading days ending on the anchor date. The window is still in the future — choose the assumption to model.

Earnings-date estimates
Several releases key off “the second full trading day after results.” Those dates are estimates until announced — adjust them to see the schedule shift.
Model an underwriter waiver
Goldman Sachs (on behalf of the underwriters) can release a lock-up early at its discretion — not predictable from the filing. Enter an announced waiver to recompute the schedule.
Supply over time
Free Float
Share of total common eligible to trade, assuming the price trigger does not fire. Scheduled and earnings-linked steps are deterministic.
Free float steps up at each unlock; the forward portion reflects the price-trigger assumption. The dashed line is potential Class A shares outstanding as Class B converts 1:1 on sale (a ceiling — it materializes only as holders actually sell). The dotted line is the fully-diluted ceiling (shares outstanding plus granted options/RSUs). The solid line is the SPCX daily close (right axis).
Beyond outstanding shares
Option & RSU Overhang
Dilutive awards are not counted in shares outstanding, but add Class A-equivalent supply when exercised or settled and sold. This sits above the lock-up schedule — the dotted ceiling on the chart above.

Plus 323.3M (2.5%) reserved-but-ungranted plan capacity (A&R 2024 Plan reserve, A&R 2017 ESPP reserve), shown for context — no holder yet, so excluded from the overhang figure.
Options and RSUs are excluded from shares outstanding but add Class A-equivalent supply when exercised/settled and sold (Class B converts 1:1). Timing depends on vesting and exercise, so these sit above the lock-up schedule rather than on a fixed date.
Forward schedule
Unlock Timeline
Date-gated steps are deterministic; earnings-linked steps use estimated results dates; the price-trigger step depends on the assumption above. Dates marked waivable are the contractual maximum — Goldman Sachs may release earlier.

Days of ADV = shares released ÷ trailing average daily volume. * Forward events use the most recent trailing ADV; volume is not projected. “Est.” dates are earnings-linked estimates. Class B shares convert 1:1 to Class A on sale.
