SpaceX's IPO lands, and Wall Street cannot decide whether to toast it or run

The SpaceX listing, trading under the ticker $SPCX, opened to a market that cannot agree on what it is holding. On 16 June 2026, Jim Cramer publicly characterised the stock as a memestock, while options flow data posted at 14:01 UTC showed net call premiums running positive against negative net put flow. An hour earlier, Unusual Whales had reported that SpaceX would acquire the AI coding firm Cursor in a $60 billion all-stock deal, and by 12:57 UTC Evercore ISI had suggested the listing could "reignite" the bull market. In other words, the first trading session is delivering the classic late-cycle contradiction: a marquee listing being treated simultaneously as a foundational infrastructure investment and as a trade to flip.

The structural argument worth holding onto is straightforward. A company that spent two decades as a private enterprise, built largely on bespoke debt and government launch contracts, is now asking the public markets to underwrite its next phase. The Cursor acquisition, if priced as reported, would be the largest AI-infrastructure deal of the cycle and would fold a developer-tools company into an entity whose valuation is itself the variable in question. Markets cannot price the deal until they have priced the equity. That is the bind the IPO has created, and it is the bind Cramer is naming.

What Cramer is actually saying

Calling a name a memestock is not a moral judgement; it is a market-structure observation. It means the trading is being driven by narrative, by retail flows, and by reflexive price action as much as by discounted cash flow. Cramer's framing, surfaced on Unusual Whales' X account at 15:37 UTC, lands at exactly the moment the public is gaining its first real read on the order book. The complaint is not that the business is bad. It is that the price discovery is being warped by attention, and that a $60 billion acquisition announced in the same news cycle makes the distortion worse, not better.

The options tape tells a different story

The bullish framing comes from the derivatives market rather than the cable-news desk. Day-one data shows net call flows positive and net put flows negative — code for buyers paying up for upside rather than hedging downside. The unusualwhales.com overview page for $SPCX captures that asymmetry in real time. If the put-call skew is genuinely this lopsided, the smart-money positioning is at least not bearish. Evercore ISI's note that the IPO could reignite the bull market sits comfortably with that read: a marquee listing pulls capital off the sidelines, and derivatives traders are positioning for the pull, not the fade.

Why both can be right

There is no contradiction between "this is a memestock" and "the options flow is bullish." One describes the price-formation process, the other describes the directional bet. A stock can be inefficiently priced and still trending up. A stock can attract retail euphoria and still find institutional buyers willing to pay for upside calls. The historical analogues — Tesla in 2020, Rivian on debut, the early days of the post-IPO Snowflake trade — all featured this exact split between the structural sceptics and the momentum desks. The structural sceptics were eventually right about price discovery, and the momentum desks were eventually right about the trend. The question is which one is right first.

The structural frame, in plain prose

What is actually happening is a transfer of pricing authority from a closed private market to a public one that has lost the habit of pricing anything that is not a software-as-a-service subscription. The private market priced SpaceX through bespoke rounds, sovereign co-investors, and insider patience. The public market prices it through algorithmic order routing, options gamma, and a 24-hour news cycle that turns a $60 billion acquisition into a meme within an hour. The inefficiency is not in the underlying business; it is in the translation layer between the two markets. That is the gap the next several quarters will close, and it will close through volatility, not through consensus.

The stakes are unusually concentrated. If the listing holds and the Cursor deal clears without a valuation reset, the IPO window reopens for a backlog of private companies that have been waiting for a positive tape. If it cracks, the window closes for at least eighteen months, and the venture ecosystem absorbs the shock. Retail traders who loaded day-one calls have the most to lose in the short term; long-only allocators who missed the private rounds have the most to gain if the public listing gives them a cheaper entry than the last private mark. The Cursor employees who receive stock have the most to gain in absolute dollar terms, and the most to lose if the equity that pays for their package gets repriced.

What remains genuinely uncertain is the acquisition itself. Unusual Whales reported the $60 billion all-stock structure, but the terms, the closing timeline, and the regulatory review are not in the public record yet. Until those are disclosed, the deal is a headline rather than a transaction, and headlines are exactly what the memestock framing is built on. This publication will treat the Cursor acquisition as reported and not as closed until primary documentation appears in regulatory filings.

Desk note: Monexus has framed this debut through the lens of market structure — the gap between private price discovery and public price discovery — rather than through the celebratory "new bull market" framing some sell-side desks reached for in the first session. The point is not whether the IPO is good. The point is what the IPO is doing to the price of the equity that pays for everything else.
