- SpaceX float rises gradually from 4.9% to ~40% before 2027 step changes unfold.
- Day 366 triggers a major shift as Musk stake becomes eligible to lift the float to ~96.9%.
- ARK Invest rebalanced $163M sales after buying $500M SpaceX shares on IPO day.
The early trading framework surrounding SpaceX’s public listing has drawn attention from market participants following the release of a staged share unlock timeline that maps out how available supply is expected to expand over time.
The schedule outlines a structured progression beginning with a limited free float of approximately 4.9%, followed by multiple incremental unlock phases extending through 2027. The model shows liquidity rising in steps across several key dates, including Aug 8 at ~11.8%, Aug 20 at ~15.2%, Sep 9 at ~17.7%, Sep 24 at ~20.1%, Oct 9 at ~22.6%, and Oct 24 at ~25.1%, before reaching ~40% by Dec 8.
Further scheduled increases continue into 2027, including ~44.1% by Mar 18, ~46.7% by May 17, and ~50.8% by Jun 12, based on the reported structure.
Structured Float Expansion Path
The timeline describes a controlled release mechanism in which additional shares enter circulation in stages rather than through a single unlock event.
According to the schedule, the major structural shift occurs after the initial trading period, where early restrictions ease and the available float expands beyond the initial baseline. The framework follows a phased approach through late 2026, with repeated increases in tradable supply leading into the following year.

Day 366 Eligibility Shift
A key point in the structure occurs on Day 366, when Elon Musk’s estimated 46.1% stake becomes eligible for sale upon the expiration of a lock-up period. At this point, the reported free float is projected to move from roughly 50.8% to about 96.9% in a single adjustment, representing the largest step change in the schedule.
The framework further extends toward ~99.5% availability by August 2027, with full 100% unlock projected by September 2027. The structure highlights that eligibility for sale does not indicate actual transactions but rather the removal of restrictions on expected supply.
ARK Invest Positioning After Listing
Following the initial public offering, ARK Invest adjusted its portfolio exposure linked to SpaceX. The firm sold approximately $163 million in equities on June 16, 2026, including positions in Tesla, AMD, and Roku, as part of rebalancing activity tied to its SpaceX allocation strategy.
Prior to the sales, ARK purchased about 3.3 million SpaceX shares valued at more than $500 million across multiple ETFs on the listing day, June 12, when the company debuted at a reported valuation of $1.75 trillion.
Fund flow activity surrounding ARK’s flagship ARK Innovation ETF also reflected heightened volatility, with a reported $4.6 billion inflow ahead of the listing followed by a $6.2 billion outflow in subsequent days.
