Could Anthropic actually go public at over $300 billion while still burning cash like crazy? Sources say early IPO talks are already happening – and they want to beat OpenAI to the punch. The AI arms race just hit Wall Street...

Financial market analysis from 03/12/2025. Market conditions may have changed since publication.

Have you ever watched two heavyweight fighters circle each other in the ring, both knowing the next punch could change everything? That’s exactly what I’m seeing right now in the AI world, except the gloves are coming off on Wall Street instead of in Vegas.

Something massive is brewing behind closed doors at one of the hottest AI companies on the planet. The team that built Claude – you know, the chatbot that’s been giving the industry leader a serious run for its money – appears to be quietly laying the groundwork for what could become one of the biggest tech IPOs we’ve ever seen. And the rumored numbers? They’re the kind that make even seasoned investors do a double-take.

The Quiet Preparations for a Monster Listing

Word on the street – or more accurately, word from people who actually know – is that the company is already working with top-tier legal counsel that’s handled some of the most iconic tech debuts in history. Think the kind of law firm that helped take search giants and ride-sharing revolutionaries public. When you start seeing those names attached to a private company, you pay attention.

But here’s where it gets really interesting. They’re not just dipping their toes in the public markets water. Sources suggest the company has been having early, informal conversations with the biggest investment banks on the planet. The same banks that orchestrate the kind of listings that make global headlines and move markets.

I’ve been around tech long enough to know that these “informal” chats rarely stay informal for long. When a company at this stage starts bringing in the heavy hitters, it’s usually because the internal machinery is already turning toward a public debut. And in this case, the timeline people are whispering about? Potentially as soon as next year.

The Eye-Popping Valuation Being Discussed

Let’s talk about the number that’s making jaws drop across Silicon Valley and Wall Street trading floors alike: north of $300 billion. Yes, you read that right. Three hundred billion dollars. With a B.

To put that in perspective, that would immediately catapult this company into the rarest air of corporate valuations. We’re talking about joining a club that currently has only a handful of members worldwide. And they’re having these conversations while still being a private company that’s, by all accounts, burning through cash at the kind of rate that would make most traditional investors run for the hills.

But this isn’t your grandfather’s IPO market anymore. The rules have changed dramatically in the AI era, where future potential seems to matter far more than current profitability. It’s a bit like valuing a gold mine based on how much gold people believe is in the mountain rather than how much has actually been dug up so far.

Companies at this scale and revenue level often start operating as if they’re already public – it’s just good governance at that point.

The Private Funding Alternative That’s Equally Stunning

Even more fascinating? This potential IPO preparation isn’t happening because they’re desperate for cash. Far from it. There’s apparently a parallel track where they’re discussing a massive private round that could push that valuation even higher.

The names reportedly involved in these private discussions read like a who’s who of tech giants. We’re talking about commitments that could total $15 billion from two of the most important players in the entire AI ecosystem. The kind of companies that don’t just write checks – they shape the future of computing itself.

This creates an interesting dilemma. Why go public if you can raise billions privately at ever-higher valuations? The answer likely lies in what going public actually provides beyond just capital. Liquidity for early investors and employees. A public currency for acquisitions. The ultimate validation in the tech world.

  • Immediate liquidity for long-term believers
  • Stock as currency for future deals and talent acquisition
  • Public market validation of the company’s vision
  • Pressure and transparency that can actually improve operations
  • The prestige that comes with being a public company

A Direct Race with the Industry Leader

Perhaps the most delicious part of this entire story is the competitive dynamic at play. This wouldn’t just be another tech IPO. It would be a direct challenge to the company that’s been dominating AI headlines for years now.

Think about it – two companies that have been battling for AI supremacy suddenly racing each other to the public markets. It’s not just about raising money anymore. It’s about narrative control. About who gets to claim they’re the true leader as AI transforms every industry on Earth.

Investors I’ve spoken with see this potential listing as a way to “seize the initiative.” And honestly? I get it. Being first matters enormously in tech, especially when you’re the challenger going up against the established champion.

The Recent Moves That Make This Feel Inevitable

You don’t make the kind of hires and investments this company has been making unless you’re thinking very seriously about life as a public company. The recent addition of a finance executive who helped orchestrate one of the most successful consumer tech IPOs of the past decade? That’s not a coincidence.

Neither is the aggressive expansion we’ve seen. Massive AI infrastructure buildouts. Tripling international headcount. These aren’t the moves of a company planning to stay private and quiet. These are the moves of a company that’s building an empire and preparing to show the world what it’s worth.

In my experience covering tech companies through their growth phases, these patterns are remarkably consistent. When you start seeing this combination of elite hires, massive infrastructure investment, and quiet Wall Street conversations, a public listing usually isn’t far behind.

What This Means for the Broader AI Investment Landscape

Make no mistake – whenever this company does go public (whether next year or the year after), it will be a defining moment for the entire AI sector. This won’t just be another tech IPO. It will be a referendum on whether public market investors are ready to value AI companies the way private markets currently do.

We’re talking about a company that will almost certainly be deeply unprofitable at the time of listing. Burning billions on research, infrastructure, and growth. Yet potentially valued higher than century-old industrial giants that generate tens of billions in actual profits.

That’s the new reality of AI investing, and this IPO could either validate that reality or throw cold water on the entire sector’s sky-high valuations. The stakes couldn’t be higher.

The Bigger Picture: Are We in Bubble Territory?

Let’s be real for a moment – these valuation numbers are objectively insane by any historical standard. Companies trading at 100x revenue or more. Private rounds pushing valuations into the hundreds of billions for businesses that lose money every single day.

But here’s the thing that keeps me up at night: what if this time really is different? What if the companies building foundation models actually do end up being worth trillions because they fundamentally reshape the global economy?

Or what if this is 1999 all over again, and we’re just witnessing the greatest wealth transfer from public market investors to private ones in history?

The truth is probably somewhere in between. Some of today’s AI giants will indeed become the most valuable companies in history. Others will flame out spectacularly. The hard part is figuring out which is which before everyone else does.

Why Timing Matters More Than Ever

There’s another angle that doesn’t get discussed enough. The company that goes public first in this AI generation gets to set the benchmark. They get to define what “reasonable” valuation looks like for foundation model companies.

If the first major AI IPO trades up massively, it opens the floodgates. Every other company gets to point to that precedent when justifying their own valuation. But if it trades down or struggles, suddenly everyone else has to adjust their expectations downward.

Being first isn’t just about prestige. It’s about controlling the narrative and setting the terms for an entire generation of AI investments.

The Bottom Line

We’re standing at the precipice of something historic. The next twelve to twenty-four months could see multiple AI companies with valuations that would have been unthinkable just a few years ago make their public market debuts.

And the company behind Claude appears determined to be at the front of that wave rather than riding in its wake. Whether they actually pull the trigger on an IPO next year or continue raising privately at ever-higher valuations, one thing seems certain: the AI arms race has officially expanded from research labs to trading floors.

Buckle up. The next chapter of the AI revolution is about to be written in stock tickers and earnings calls, and it’s going to be one hell of a show.

Don't try to buy at the bottom and sell at the top. It can't be done except by liars.
