But what's the $60B differentiator here? There are so many similar tools out there. I generally use Opencode, but also Claude code, antigravity and sometimes Kilo code on VS Studio. How can cursor be worth even 10% of 60B?

I don't know what cursors market share is but it feels like 20-25% to me. That is not worth nothing. Then;

1) The data they have flowing through the system that enabled them to build composer (which is much better than stock kimi 2.5) and is presumably allowing the training of a new model on space Xs compute.

2) Cursors new 'github' replacement.

3) Enterprise sales/traction

If you look at all of these together, it's not implausible that they end up mostly 'owning' coding in 5 years time. If they replace GitHub with something more compatible with agentic coding and bring it into their whole ecosystem providing cloud and local agents, PR review and own frontier coding model.

It's specialised vs 'borg' isn't it. One way of thinking is that the world is owned by Anthropic/OpenAI and coding is just one of many things their model and software does. Another view is we have a 'coding with LLMs' company that specialises in this field of endeavour. Hard to say which wins, but I think they have a shot.

Personally my only objection to cursor is that it's more expensive. That's it, otherwise it is great to be able to choose say GPT-5.5 when I want to work on backend and Opus when I want to work on front end. Great to have PR review built in. If they were able to get composer 3 to as good as GPT5.5 / fable at the price of composer 2.5 they'd be winning on price again.

I believe they have some very good training data because of all the data generated by people using the service.

This is the same data they used to finetune Kimi K2.5 to make their newer Composer models, which benchmark substantially better than Kimi K2.5.

I've heard they also want to build their own base models, which will also benefit from their large amount of high-quality training data. Which will solve Grok's model quality problem.

This is all unsourced conjecture of course. But it's what I've heard.

> How can cursor be worth even 10% of 60B?

Maybe because SpaceX paid with monopoly money (all stock deal)?

they are paying for marketshare/customer base. Cursor has a good chunk of it.

xAI overbuilt their data centers - they can't find paying customers for them, that's the reason they made deals with other companies like Google to use their own datacenters.

Cursor has the opposite problem of not having enough capacity. So this works well for them together.

Weather it's worth it - if you beleive that AI will solve every problem then having a piece of the pie early on might be worth it.

Remember how when google bought youtube for 1.65 billions people thought they are crazy? Or when facebook bought instagram.

60B is a crazy number but might be worth it for someone fighting for world dominance :)

Where else are you going to get access to a real-time fresh high quality stream of human intelligence to grow your baby AGI? You can’t buy Codex, Claude, Copilot, so what’s left?

I think the argument for Cursor is that it's the dominant tool that enterprises are using for coding, so the theory is Cursor wins that as the "model agnostic", it has a phenomenal Enterprise Sales Team.

From a valuation model - $4B ARR with rapid growth, and the ability to shift traffic to internal models (honestly, massive amount of the time "composer" - their internal model is fine, and obviously going to get better). Say 17x Multiple which isn't unheard for a rapidly growing Startup with solid future structural profit elements (moving to internal model) - that gets you to $68B.
