SPCX Slides to $204 as the All-Stock Cursor Math Cuts the Wrong Way

No Fresh Catalyst, Just Repricing

SPCX is down 5.78% to $203.90 over the last 14 hours, the second straight session of giving back ground after the stock printed an all-time high of $225.64 on Tuesday. There's no new headline behind today's leg lower — no downgrade, no filing, no operational miss. This is the post-IPO premium being repriced, not a reaction to fresh news.

Rewind two weeks for scale. SpaceX priced its IPO at $135 on June 11, raising roughly $75 billion in the largest listing ever, then closed its debut up 19% near $161. From there it ran another 40% into Tuesday's record as the company unveiled its first deal as a public company. At $203.90 the stock now sits about 9.6% off that peak, and the tape reads like consolidation digesting a vertical move rather than a verdict on any new information.

The All-Stock Math Cuts the Wrong Way

The catalyst that drove SPCX to its high is the same one now under the microscope: a $60 billion all-stock acquisition of Anysphere, the company behind the Cursor AI coding tool, signed June 16. Per the 8-K, merger sub X67 folds into Cursor and the transaction is expected to close in Q3.

Here's the detail that matters for the tape. The deal value is fixed at $60 billion, but the share count is not — Cursor holders receive SPCX Class A stock equal to $60 billion divided by the seven-day volume-weighted average price just before closing. A fixed-value, floating-share structure means the math works against existing holders: the lower SPCX trades into the close, the more shares SpaceX must print to deliver $60 billion of value, and the more dilution longs absorb. Today's price locks in nothing — the VWAP is struck near the Q3 close — but a stock that keeps fading is quietly worsening its own future dilution, which is itself a reason to discount it now.

The strategic logic is real: pairing xAI's Memphis Colossus supercomputer with Cursor's developer distribution is Musk's bid to catch rivals in AI coding. The question the market is pricing is whether a three-week-old public company should be spending $60 billion of richly-valued paper to get there.

Morningstar's $62 Problem

The valuation is where the skepticism lives. After the Cursor deal, Morningstar cut its fair value estimate to $62 from $63 — roughly 69% below spot — and now ranks SPCX among the most expensive names in its entire coverage universe. At current prices the stock trades around 3.2x that fair value, about 141x 2025 sales and 78x projected 2026 sales, more than triple Broadcom's multiple and over 25x Amazon's.

The bear case isn't about ambition; it's about timing. Morningstar's own best-case scenario gets the stock to $154 but carries just a 7% probability, and the firm notes the two engineering problems underwriting the bull thesis — rapidly reusable Starship and orbital AI data centers — aren't expected to be solved before 2028. At $203.90, the market is paying today for execution that, on the most credible third-party model, is years out. That gap is what a stock that added 17% on deal day is now negotiating back down.
