For weeks, the debate around Space Exploration Technologies Corp. (NASDAQ:SPCX) has centered on one question: Is the stock too expensive? George Noble, a former Peter Lynch protégé and veteran market strategist, argues investors are focused on the wrong risk.

In a note published this week, Noble said SpaceX’s biggest challenge isn’t its triple-digit price-to-sales multiple—it’s a lockup schedule that could increase the stock’s tradable float by roughly 900% over the coming months as insider shares become eligible for sale.

SpaceX Stock: From Scarcity To Supply

Noble argues SpaceX’s post-IPO rally was driven as much by supply constraints as investor enthusiasm.

Less than 5% of the company’s shares were freely tradable when the stock debuted, he noted. Shortly afterward, Nasdaq-100 inclusion and Russell index rebalancing forced passive funds to buy billions of dollars’ worth of shares while the public float remained exceptionally small.

“The supply was minuscule and the buying was mandatory,” Noble wrote. That dynamic helped propel SpaceX above $225 during its first week of trading before shares began retreating.

The Calendar That Matters

According to Noble, the next phase of the story is already mapped out in the company’s prospectus.

The first meaningful unlock arrives after second-quarter earnings, when 20% of locked shares become eligible for sale. Another early release could occur if the stock meets a price-based performance trigger.

From late August through October, additional tranches are scheduled to unlock every few weeks. The largest release comes after third-quarter earnings, followed by the expiration of the six-month lockup in December.

Noble estimates insiders could be free to sell as much as 44% of the company by early September, increasing the tradable float by roughly 900% from IPO levels.

A Different Kind Of Bear Case

Unlike traditional short theses built around deteriorating fundamentals or disappointing earnings, Noble argues the catalyst is already visible.

“It’s literally a published calendar,” he wrote.

He contends that thousands of early employees and private investors who acquired shares at substantially lower valuations may choose to monetize their holdings once restrictions expire.

Noble also questioned the company’s valuation, noting that SpaceX has yet to report an annual profit and traded above 90 times revenue at its IPO, with the multiple briefly approaching 140 times during the stock’s early rally.

While he described Starlink as “a wonderful business,” he argued it does not justify the company’s multi-trillion-dollar valuation on its own.

Why Investors Are Watching

Lockup expirations don’t always trigger sharp declines. Some insiders hold their shares, while strong institutional demand can absorb new supply.

But Noble believes SpaceX’s combination of a historically small IPO float, rapid index inclusion and staggered insider unlocks makes this one of the most unusual supply-demand setups he has seen.

His conclusion is blunt: the story investors should be watching isn’t just how SpaceX performs—it’s how many shares suddenly become available to sell.
