$51B in 2026. $274B in 2027. $731B in 2028.

That is Sequoia partner Shaun Maguire’s revenue forecast for SpaceX. That is 12.5 times what the company is doing today.

Elon Musk replied on X: “I think we can do better.”

The model in four numbers:

  • $51B of revenue in 2026, $274B in 2027, $731B in 2028

  • 78% of the 2028 total comes from one line: renting out AI compute

  • $747B of capex over three years, and 250 Starship flights in 2028 alone

  • Bernstein, after raising its numbers last week, sits at $424B for 2028

Its author? The partner who has led Sequoia’s SpaceX investments since 2020. He opens the post by calling himself extremely biased.

We checked it line by line against SpaceX’s Q3 results, the earnings call and the Street.

→ The first year of the model is already close to what SpaceX told investors. The 2028 number rests on a few bets, and the biggest one is a price.

📚 In this newsletter, I break down where the $731B comes from, which numbers are already real, and how to stress-test any model like this one!
