Market values and last rounds are facts as of 2026-10-26. *What today's value implies in our model, with our middle-case margins: an assumption, not a forecast. Open a company and set your own.

How it works

  1. Pick a company and a starting case. Bear, middle, bull, the CEO's own case, or the "market's view": the growth today's price already assumes.
  2. Move the sliders. Simple mode moves the whole company; Advanced lets you set growth and margins for each business line, plus the big bets like robotaxis, Optimus or orbital data centres.
  3. Read the needle. Your value against today's price, from Bubble to Bargain. If it doesn't add up, we tell you how much revenue aliens would have to buy (or, for the AI companies, how much the AI will have to figure out).
  4. Explore the moonshots. Asteroid mining, robot carers, AI that cures diseases: markets that don't exist yet, each valued like an option you can switch on.
  5. Share and compare. Copy a link, export to Excel or PDF, or post your call to a group board and see which friend was right.

The AI boom in numbers

Why we built it

SpaceX listed in June 2026 at $135 a share and now trades above $2 trillion. Anthropic filed its prospectus on 26 October 2026, and OpenAI and Tesla talk in trillions too. Headlines give you the number; nobody shows you what has to be true for it to make sense. Stonkometer takes the companies' own filings, splits them into business lines and lets you decide. No sign-up, no tips, no stock picks: just your numbers.
