SpaceX

A week after the IPO, SpaceX is no longer trading mainly as a Mars story. It is trading as a public-market machine in which float, options, index rules, lockups, merger arithmetic and debt capacity all feed back into the same variable: SPCX.

The Cursor deal turns SPCX from a market verdict into an acquisition input. SpaceX is now using the public float, options market, ratings shelf and Starlink cash flow as parts of the same capital machine.

The options market has made SpaceX trade less like a newly public aerospace company and more like a market-structure instrument. The issue is not whether a squeeze has happened, but whether price, float, options flow and all-stock dealmaking have become mutually reinforcing inputs.

SpaceX’s $60 billion all-stock deal for Anysphere is a filing-grounded pivot from launch and satellites toward AI infrastructure. The risk is that the AI buildout still depends on large, terminable compute leases while the segment is deeply loss-making.

The debut was not just a capital raise. It created a small public float, huge demand, staged insider liquidity and a plausible index-buyer chase before meaningful supply arrives.

The $75 billion IPO gave public investors a low-vote slice of rockets, Starlink, defense launch and AI-compute leases. The tape loved the scarcity. S&P did not: no fast track, no float, no profits yet.

SpaceX had the biggest IPO in history on Friday. By the closing bell Elon Musk was the first trillionaire, about 4,000 employees were millionaires, and the people who put up the money got almost none of the votes. Here's what they actually bought.
