CNBC’s Jim Cramer is making a paradoxical name on the pending SpaceX IPO. On Squawk on the Street this week, he predicted the inventory might double on its opening commerce to a $4 trillion valuation, whereas publicly attempting to discuss retail traders out of shopping for. The mechanics he factors to (a microscopic float and compelled index-fund demand) are the identical mechanics he warns might entice anybody chasing the pop.
The largest beneficiaries of this IPO sit on Wall Street. Goldman Sachs (NYSE:GS | GS Price Prediction) secured the first underwriter position, whereas Morgan Stanley (NYSE:MS) handles the retail allocation Cramer is speaking about.
The Fixed-Price Setup
Elon Musk opted for an uncommon construction with a set worth of $135, implying a $1.77 trillion valuation moderately than a standard worth vary. SpaceX plans to elevate $75 billion and is ready to debut on NASDAQ a couple of week from Cramer’s phase. That fixed-price selection removes regular book-building discovery and shifts all worth discovery to the primary commerce, the place Cramer’s concern begins.
Factor One: The Tiny Float
The SpaceX S-1 confirms the lock-up structure Cramer is pointing to. Per the submitting, the Founder and sure vital traders have agreed with the underwriters that in a interval of three hundred and sixty six days after the date of this prospectus, an combination of shares owned by them (together with 100% of the shares owned by the Founder) are restricted. Most different holders face a 180-day lock-up, with releases managed by Goldman Sachs & Co. LLC, on behalf of the underwriters.
This implies that little or no inventory is tradable on day one. Scarce provide will doubtless meet keen demand, and modest shopping for can violently spike the worth.
Factor Two: Forced Index-Fund Demand
Once an organization this huge lists and qualifies for main indexes, passive funds monitoring these benchmarks should purchase. They are price-insensitive by design. Layer that mechanical bid on high of a tiny float, and also you get the situations Cramer is betting on. As he put it, “I am trying to influence Morgan Stanley, which has got the retail part to say to discourage their people from putting in market orders because they may get the stock to $4 trillion just by their own.”
Cramer’s Warning: The Cerebras Parallel
Cramer’s deeper concern is what occurs after the pop. He invoked Cerebras, which on its May 14, 2026 debut priced at $185 and opened at $350, briefly buying and selling as excessive as $386 earlier than closing at $311. As of right this moment, Cerebras trades at $218 per share.
His verdict on SpaceX: “It could be very much like 1999, where they opened it at 4 trillion and then walked it down. If you look at Cerebras, that is a disaster. Everybody who bought Cerebras between 320 and 360, well, they are not ever going to buy another stock.” He is candid about his personal first-day wager: “SpaceX doubles at the opening, as I think it will. I have it on DraftKings. I am looking good.”
What It Means for GS and MS
Goldman is already pricing in a robust first half of the yr. Shares are up 19.56% yr to date and 75.84% over one yr. This fall 2025 advisory income hit $1.356 billion, up 41% YoY, with full-year funding banking charges of $9.34 billion. CEO David Solomon informed traders the agency expects “momentum to accelerate in 2026, activating a flywheel of activity across our entire firm.” A SpaceX charge pool of $800 million to over $1 billion throughout 22+ banks would land squarely in that flywheel.
Morgan Stanley sits on the retail-distribution facet that Cramer is attempting to affect. The agency posted report Q1 2026 outcomes with income of $20.58 billion, EPS of $3.43, advisory income up 74% YoY, and ROTCE of 27.1%. Shares have climbed 19.64% yr to date. Wolfe Research individually flagged a wealth administration enhance from Shareworks inventory plan administration, securities lending, and conversion of SpaceX staff into advisory shoppers.
The Takeaway
Cramer’s framework is a warning dressed as a prediction. The tiny float and compelled index demand that would produce a spectacular pop might make shopping for within the open market harmful as a result of the worth has nowhere to go as soon as index inclusion is full and lock-ups unwind. SpaceX’s sturdy worth hinges on years-away execution on Starship integration and Starlink v3. For on a regular basis traders, the sensible lesson is to keep away from market orders on a mega-cap IPO debut.
