CNBC’s Jim Cramer said Thursday he’s worried about what’s next. space x Stock prices may rise too quickly.
“If things really go wrong this time tomorrow, there could be a new champion, a new world’s biggest stock, SpaceX,” the “Mad Money” host said.
Elon Musk’s rocket and artificial intelligence company is scheduled to begin trading on Friday. The fixed sale price was set at $135 per share and the valuation was set at $1.77 trillion. Demand for the IPO was extraordinary, with the deal reportedly being four times oversubscribed. While this level of interest is generally viewed as a positive, Kramer cautioned that excessive demand could cause its own problems.
In his view, the best IPOs start trading slightly above the offering price and then trade in an orderly manner. But SpaceX faces a unique combination of institutional demand, retail enthusiasm and future index buying that could send the stock soaring soon after trading opens.
Cramer said he was particularly concerned about the possibility that inexperienced investors could place market orders instead of limit orders, pushing stock prices to unsustainable levels.
“These are new types of unguided missiles that you can’t control,” Kramer said.
Cramer said SpaceX’s valuation could temporarily rival or exceed the world’s largest publicly traded companies if enough buyers flood in at once. But he cautioned that such moves rarely work.
“Are we really going to have $4 trillion to $5 trillion in stocks? Probably about the same amount of time as a marlin gaffes for a few minutes,” he said. “It’s a great catch, but if you don’t pack it up and attach it quickly, it’ll stink to the heavens.”
Regarding recent IPOs, he pointed out that: figma July 2025 and cerebrum In May, it initially “continued to rise, but then began a long decline.”
Ultimately, Kramer said the goal should be a controlled debut that can increase the stock’s value over time, rather than a dramatic jump on the first day.
“We want the deal to be brought under control because otherwise the consequences could be dire,” he said.
