319 million shares are about to be unlocked, yet SpaceX has climbed back above its IPO price—what exactly is the market betting on? SpaceX closed around $146 on August 17, while approximately 319 million shares held by early investors and insiders will become tradable on August 20.

In one sentence: The market knows a large batch of potential sell-side supply may soon emerge, but money is still flowing in ahead of time.
More interestingly, approximately 911.5 million shares were already unlocked on August 6. Many people expected to see a stampede, but SpaceX did not collapse that day and instead continued to rebound afterward. This shows that the market is no longer trading just a “rocket company,” but rather three stories stacked together: Starlink + a launch monopoly advantage + AI infrastructure.
The latest financial report also gave the bulls confidence: SpaceX’s second-quarter revenue was $7.8 billion, nearly doubling year over year, while Starlink revenue grew 66% and now contributes more than half of the company’s revenue. In other words, what is really underpinning SpaceX’s valuation is no longer “going to Mars someday,” but satellite internet that is generating revenue today.
But I think August 20 will be the real stress test. Early investors’ cost basis is far below the current price, and if even some of them choose to cash out, the additional supply will be enough to amplify volatility.
Scenario A: If the 319 million unlocked shares still cannot be sold, it would show that institutions are willing to continue absorbing the supply, meaning this SpaceX rebound is more than just an oversold recovery.
Scenario B: If trading volume surges after the unlock and the share price falls back below the $135 IPO price, it would show that the earlier rise was driven more by trading on the idea that “the selling pressure is not as large as imagined.”
What matters more now is not whether SpaceX can tell an even bigger space story, but how much capital is still willing to absorb the unlock-related selling pressure with real money. That answer will say more about the valuation the market is assigning SpaceX right now than the next rocket launch.
