Jim Cramer told viewers of CNBC’s Mad Money to think of SpaceX as a hundred-year investment, comparing the company to a railroad bond from a previous century. The comment came during the show’s August 5 broadcast, as roughly 911 million shares tied to an early lockup agreement became eligible to trade.

Cramer said investors fixated on near-term volatility around the lockup expiration are missing the larger opportunity. He argued that some of SpaceX’s most ambitious projects, including deep space missions, could take years or even decades to pay off, and that patient shareholders willing to hold across that stretch stand to benefit the most.

The host pointed to Starlink as the business funding SpaceX’s longer-term ambitions. The satellite internet service now operates in 167 countries and added 1.7 million subscribers in a single quarter, according to figures Cramer cited on the show. That growth, he said, gives SpaceX the cash flow to keep investing in Starship and other programs without leaning as heavily on outside capital.

Cramer also invoked Elon Musk’s record at Tesla to make his case. He said Musk has proven he can raise money when he needs it, pointing to Tesla’s history as evidence that investors have repeatedly backed Musk’s long-term vision through rocky stretches. Cramer suggested SpaceX shareholders apply the same patience, framing the stock as something to buy for children or grandchildren rather than trade around short-term news.

The remarks come as SPCX, a fund offering investors exposure to SpaceX shares, has traded through a string of down weeks. Cramer’s railroad-bond comparison was meant to reset expectations around a stock most retail investors cannot buy directly, since SpaceX remains private and trades only through secondary vehicles like SPCX and similar funds.

Cramer did not set a price target or timeline for when lockup-driven pressure might ease. He said his advice stands regardless of how the stock trades in the coming weeks, calling SpaceX a name to accumulate rather than trade.
