SpaceX IPO Filing Reveals Aggressive Deadlines: Starship, Starlink V3, Orbital Data Centers, and a $60B Cursor Decision

SpaceX's landmark IPO filing — one of the most unconventional S-1s in recent memory, complete with sci-fi language and a CEO pay package tied to putting humans on Mars — lays out a dense calendar of high-stakes milestones across its most critical business lines. The document confirms that Starship, still in test-flight phase with its next launch imminent, is the linchpin for nearly every major revenue ambition the company has.

The most immediate deadline centers on Starship's commercial debut: SpaceX expects the reusable rocket to begin actual payload delivery to orbit in the second half of 2026. That same window is when the company plans to start deploying its next-generation V3 Starlink satellites — each capable of one terabit per second of downlink capacity, a massive leap over current hardware. A single Starship launch can carry 60 V3 satellites to low Earth orbit, making rocket reusability a direct multiplier on broadband revenue.

The filing also sheds light on SpaceX's deal to potentially acquire Cursor, the AI coding startup it secured the right to buy for $60 billion back in April. SpaceX has a 30-day window to pull the trigger, beginning either seven days after its shares start trading publicly or after September 30, 2026 — whichever comes first. If it walks away, it owes Cursor roughly $10 billion. Separately, the company disclosed it borrowed $20 billion to retire loans tied to X and xAI (with which SpaceX has already merged), with that debt maturing in September 2027 and an optional extension to March 2028.

Looking further out, SpaceX aims to close its spectrum deal with EchoStar — already FCC-approved — by November 30, 2027, unlocking the ability to beam broadband directly to smartphones via V2 Starlink satellites also slated for 2027 deployment. The most futuristic timeline item is orbital AI data centers powered by solar energy, which SpaceX says could begin deployment as early as 2028. The company was candid that scaling space-based AI compute into a real business requires full Starship reusability to make the economics work — meaning every milestone on this list is downstream of that one rocket.
