Most of the coverage you'll read today will tell you Anthropic just "filed for an IPO." That's technically true but it misses the actual story here, which is that we're watching two companies worth nearly $2 trillion combined sprint toward public markets like it's 1999 and the NASDAQ is handing out free money. Spoiler: it kind of is.
Anthropic submitted its draft registration statement to the SEC confidentially on Monday, according to The Verge. The company chose the confidential route, which means we won't see the actual numbers (revenue, burn rate, how much they're spending on compute) until closer to the actual offering. Smart move. It lets them test the waters without showing their hand to OpenAI, which is presumably watching this very closely from whatever converted warehouse Sam Altman is running things out of these days.
Here's where it gets interesting. Bloomberg is reporting that this first-mover advantage could be significant, and I think they're right but maybe not for the reasons they're emphasizing. The obvious angle is fundraising, these companies are burning cash like it's their job (because it literally is), and public markets offer a different kind of capital than the VC merry-go-round they've been riding.

The Claude maker beat OpenAI to the SEC paperwork, but I've seen enough tech IPO races to know this is really about runway, not rivalry.
But the real advantage is narrative. Whoever goes public first gets to set expectations for what an AI company should look like on Wall Street. They get to define the metrics, the growth story, the valuation framework. OpenAI will have to respond to whatever Anthropic establishes. Call me old-fashioned, but that's a pretty significant strategic position.
Not much! And that's worth saying explicitly. The confidential filing means we're working with secondhand valuation data and whatever the companies have chosen to disclose in previous funding rounds.
What we do know: Anthropic's post-money valuation hit $965 billion after last week's fundraise. That makes it, according to multiple outlets, the world's most valuable startup. OpenAI is sitting at $852 billion post-money. Both numbers are, frankly, bonkers. We're talking about companies that didn't exist a decade ago being valued at nearly a trillion dollars each.
I've seen this movie before. The dot-com boom had its own version of this, two or three companies racing to prove that their particular flavor of internet business was worth more than General Electric. Some of those companies are still around. Most aren't. I'm not saying Anthropic is Pets.com (they're obviously not), but the valuation environment feels familiar in a way that makes the hair on the back of my neck stand up.
Bloomberg's sources are saying "as soon as this fall," which in IPO terms means anywhere from September to, realistically, whenever the market conditions look right. The number of shares and the price haven't been set yet, which is normal at this stage.
The timing is interesting though. If Anthropic can get out before OpenAI, they potentially lock up investor attention and capital during what could be a narrow window. There's only so much appetite for AI IPOs, even in a market that seems to have unlimited appetite for AI everything else. First mover gets the freshest capital.
These companies are in an arms race for processing power, and that costs money, real money, the kind of money that even billion-dollar funding rounds can't sustain forever. Going public opens up a whole new category of fundraising options: secondary offerings, debt instruments, the ability to use stock for acquisitions. It's not just about the IPO proceeds, it's about everything that comes after.
Anthropic has been positioning Claude as a genuine alternative to GPT, and by most accounts they've succeeded. But success in AI means you need more compute to train the next model, which means you need more money, which means you need access to public markets eventually. The question was never if, it was when and in what order.
Too early to say, and honestly, but what do I know, I'm not sure "winning" is the right frame here. Both companies are going to go public eventually. Both are going to raise enormous amounts of money. Both are going to continue spending that money on GPUs and researchers and whatever else it takes to stay competitive.
The more interesting question is what happens to the AI industry once these companies have public market obligations. Quarterly earnings calls. Revenue guidance. The pressure to show growth that justifies those trillion-dollar-adjacent valuations. That changes how companies behave, sometimes in ways that aren't obvious until years later.
I covered the smartphone wars in the 2010s, and I remember when everyone thought the race was between Apple and Samsung. Turned out the real story was how the entire mobile ecosystem evolved once the big players went from "move fast and break things" to "protect shareholder value." We might be about to see something similar in AI.
For now, Anthropic has the filing. OpenAI presumably has its own paperwork ready to go. The fall is going to be interesting. If you want to argue about whether this is 1999 all over again, my email's on the about page.
