For 8/5/26 , the most likely answer is up to 20% of the eligible locked insider shares , not 20% of all SPCX shares outstanding. The reporting also says there could be an additional 10% if the stock meets the price- performance trigger, so the maximum first unlock around that date would be 30% of eligible locked shares.

What that means

  • The first unlock is tied to the first post-IPO earnings release in early to mid-August 2026.
  • The base release is 20% of the eligible insider shares.
  • If SPCX trades at least 30% above the IPO price under the stated trading-day condition, the unlock can rise by another 10%.

Important nuance

This is not 20% of every SPCX share ever issued. It is 20% of the shares that are subject to that early unlock bucket, while other insider shares remain under later staged release dates.

Practical read

So if you’re asking “how many insider shares unlock on 8/5/26?”, the clean answer is: 20% minimum, 30% maximum if the performance condition is met. If you want the exact share count, I’d need the number of shares in SPCX’s eligible insider lockup pool.

TL;DR: On 8/5/26, SPCX appears set for a first insider unlock of 20% of eligible locked shares , with a possible bump to 30% if the stock-price condition is triggered.
