OpenAI Acquires Windsurf, Prioritizing AI Coding
Key Points
- OpenAI acquired the coding platform Windsurf for roughly $3 billion—a 75× multiple—highlighting how critical AI‑assisted development tools have become for model makers.
- The deal underscores the intense competition in the space, where rival Cursor, valued at about $9 billion, has just added $200 million in ARR in only four months.
- Owning Windsurf gives OpenAI deep visibility into how engineers of different seniorities use various models, enabling data‑driven product decisions and model‑optimization insights.
- A fully integrated development environment is essential for OpenAI’s roadmap toward AI‑driven agents, allowing tight coupling between code generation and execution.
- Code execution provides a clear, quantifiable success signal for AI systems—a “reward” that is far easier to measure than many other AI tasks.

OpenAI has purchased Windsurf. Windsurf
is the number two AI development
platform behind cursor. If you're like
why does this matter? I will tell you
why it matters. Code and engineering are
the number one priority for most model
makers right now. So OpenAI purchasing a
coding environment underlines again how
important it is to them. And they paid a
pretty penny. Uh they paid a 75x
multiple on Windsurf reportedly. Uh so
they bought them for $3
billion and that is even more than the
multiple offered to Curser in their
latest round. They raised yet again.
They're at a $9 billion valuation. So
three times more than Wind Surf. Uh
Curser is the number one AI powered
development environment in the space. If
you want to get a sense of like how nuts
this space is right now, Cursor has
increased their ARR, their annual
recurring revenue by $200 million in the
last four
months. Like not even like a half a year
and they've added $200 million in ARR.
That's how crazy it is right now. And so
I of course thought to myself,
well, why would a model maker that has
been focused on intelligence for people
as a whole care to buy windsurf? And
people are like, well, this means that
they can have their own development
environment that they can customize
exactly the way they want. They can
optimize it for their models. Maybe
partly. I do not think it is likely
though that they are going to cut off
model access to other models from
Windsurf. If I were them, I would
actually keep it because it gives
you so much more info. It gives you a
sense of who is using what models for
what, which coding tasks works work well
for which models. And by the way, you
don't have to be looking at the details
of the code. you can have a very high
level relatively anonymized
understanding of token usage and you can
still get a sense of like a footprint of
usage that's very useful. The other
thing you can do is you can actually
start to understand the dynamics of team
usage for a tool like that in a way that
you don't get if you don't own the tool.
And so, OpenAI can basically say, hm, it
looks like this is a tool that like L5
engineers are using, but L6s aren't
using as much. This particular model is
preferred by L7 engineers versus L5
engineers. And when they get into
agentic workspaces, which, you know,
they're going for AI agents, you need a
deep and tightly integrated development
environment to make AI agents work well.
And OpenAI has been super upfront about
the fact that they like everybody else
in the space wants an AI coding agent. I
mean, join Mark Zuckerberg. He's wants
that as well. Uh join Dario Amade, the
founder of Anthropic. That's where he's
going with Claude. You might ask, why?
Why do they care so much about coding?
And the answer is multiplefold. As I've
called out on my Substack, if you can
make code run, you have a very easy
reward indicator for AI that tells you
you built a good code. You did a good
thing, the AI succeeded. That is
something you don't get with other
things. The the exact opposite happens
with something like great literature.
There's 20 million ways to write great
literature and everyone argues about it
all the time and you can't really tell
what's good and what's not. In the same
way, humans will say this is good and
this is not. But humans also disagree
with each other. That is not the case
for code. The reward clarity is really
really good. Either it runs or it does
not run. So that's reason one. It's
really easy from a machine learning
perspective to optimize there. Reason
two is that code is leverage. At the end
of the day, if you can get AI building
code, AI can build so much other stuff
because it can now code. And so just the
fact that you can get it to work with
that tool set unlocks so many other
possibilities. Dario Amade has gone so
far as to say effectively he views the
ability to code as like the key stepping
stone along the way toward AGI or
artificial general
intelligence. So so like strategically
that makes sense. I hope you are getting
a little bit more of a sense of why Sam
Alman in particular might care. The
rumor is he actually offered or asked
the cursor team first. you wanted the
number one player. The price was too
spicy. If you're growing by $100 million
in incremental ARR every 60 days, I mean
honestly, you can kind of do whatever
you want. You can be your own player.
You're in the position of Mark
Zuckerberg with Facebook in the early
2000s. You don't have to sell. So, he
went and got the number two player,
which desperately needed a cash infusion
now that Curser just raised like another
$900 million. And so Windsurf now has
the cash to actually do interesting
things. They're continuing to innovate
and ship. I will say personally, I like
the UI that Windsurf brings to the
table. I like the experience of working
with Windsurf. It feels very smooth.
Everyone's choices vary. Most people are
still choosing cursor and that's why
it's the number one player in the
space. If we think about say 2026 and
what does the landscape look like? This
enables open AI to steal a march on the
other major model makers if they don't
respond. So it puts the pressure on
Enthropic and on Google and on others
because now if OpenAI wants to roll out
an agent, they just have a channel to do
that in that's proprietary. They aren't
locked into the chat window is the only
way to touch your
desktop. And nobody else has that now.
Google doesn't have a direct way to do
that now. And neither does Anthropic.
and neither does deepseek and neither
does X. None of the other players have
that. And you better believe Sam Alman's
going to use it. And so I would expect
somebody with very deep pockets is going
to try to buy Cursor in the next few
months. I think the only player on the
board who is good enough at models,
aggressive enough, and ready to part
with money at that level is probably
Google. Amazon could afford it, but
Amazon isn't playing in the space in the
same way. And so my suspicion is if
anyone's going to buy Cursor, it's going
to be Google. And Google probably needs
to if they want to have Gemini 2.5 Pro
and the agentic power of coding be
something that Google is also known for
long term, and they care. They just
updated Gemini 2.5 Pro again today on
May 6th. And they did it in order to
jump from number three on the
leaderboard to number one again. They
really, really want their AI models to
be known as the best and the brightest
and the most cutting edge. Gemini 2.5
Pro was already a great model and they
relentlessly improved it again. So if
you're investing that much in the AI
model side, it would make sense that you
would invest in the development
environment, too. So that's my little
that's my guess. That's where I think
that's going to go. I don't think
Anthropic has the money to buy and I
think that this is going to further
cement their position as an excellent
model maker but a number two player and
it's actually somewhat risky for them
because Anthropic's position has been
predicated on the sort of classic
challenger brand approach of saying we
can't do everything good with our model.
We don't have the compute to serve
everybody but we can power engineers.
And so the reason why you get fewer
tokens in a lot of these situations in
the chat window with claude anthropics
model is because most of their tokens
are going to cursor. Most of their
tokens are going to a development
environment and engineers who are using
cloud 3.5 cloud 3.7 to code. That's the
historic case. Will that persist even if
they're not banned in Windsurf? Will
that persist long-term if they can't
maintain control of a development
environment and if other companies with
control of the development environment
release
agents? That is my question and that is
why I would stay up worrying if I were
Dario Amade. There is not an immediate
good counter for him here and I think
that he should be somewhat concerned. So
there you go. That's my take on the
Windsurf acquisition and uh we will have
to see how it all shakes out.
