The biggest companies rarely go public because they are short on cash. They go public because the people who built them, and the investors who funded them, eventually want a way to turn paper wealth into real money.
For most of the past four years, that exit door stayed mostly shut. Valuations cooled after the 2021 boom faded. Splashy market debuts dried up. A generation of richly funded startups sat in private limbo, waiting for the window to crack back open.
That window is open again, and the stampede through it is loud. Elon Musk‘s SpaceX has already filed its paperwork. OpenAI is close behind. Both are chasing valuations that would have read like a typo a few years ago.
This week, the company that may matter most to your portfolio took the biggest step of all. Anthropic, the maker of the Claude artificial intelligence (AI) assistant, confidentially filed for an initial public offering (IPO).
And it handed the most important job in the whole process, running the deal, to two of the most powerful banks on Wall Street.
What Anthropic just told the SEC about its IPO
Anthropic submitted a confidential draft registration statement to the Securities and Exchange Commission (SEC) on June 1, 2026, the company said. “This gives us the option to go public after the SEC completes its review,” Anthropic said in a statement, according to CNBC.
A confidential filing is standard for a company this size. It lets regulators review the paperwork in private before the public, and rival firms, get to pick it apart.

Then came the part Wall Street really cared about. The Claude maker picked Goldman Sachs (GS) and Morgan Stanley (MS) to lead the offering, according to Bloomberg. JPMorgan Chase (JPM) is also expected to land a key role on the deal.
When I look at who is steering this IPO, the message is hard to miss. These are the banks you hire when you expect one of the largest debuts in market history, not a routine listing.
The numbers behind the filing explain the muscle. Anthropic recently raised $65 billion at a $965 billion valuation, eclipsing rival OpenAI for the first time, reported Fortune.
That is a private company knocking on the door of the trillion-dollar club, a level only a handful of public giants like Apple (AAPL) and Nvidia (NVDA) have ever reached.
Why the Anthropic valuation jumped to nearly $1 trillion
The short answer is revenue, and a lot of it, very fast. Anthropic’s annualized revenue run rate ballooned to $47 billion this year, up from about $10 billion a year earlier, according to CNBC.
The company expects $10.9 billion in revenue for the second quarter alone, more than double the prior period, and is on pace for its first profitable quarter, reported Fortune.

A lot of that growth traces back to one product. Claude Code, the company’s coding assistant, has become a magnet for enterprise customers willing to pay real money to let AI write and ship their software.
When I lined up Anthropic’s funding rounds against each other, the speed of the climb was the thing that stopped me. The valuation has risen roughly fivefold in less than a year.
- Series F closed at a $183 billion valuation in September 2025, according to TechCrunch.
- Series G hit $380 billion in February 2026, reported TechCrunch.
- Series H reached $965 billion in May 2026, according to Fortune.
For perspective, Goldman Sachs has already mapped out a stock market forecast that stretches to 2035, as covered by TheStreet, and even its long view did not picture a single private AI lab worth nearly a trillion dollars this fast.
Two of Anthropic’s largest backers, Amazon (AMZN) and Alphabet (GOOGL), have poured billions into the company. That means a piece of this story already sits inside funds and retirement accounts that hold those two stocks.
What an Anthropic IPO means for your portfolio
Here is the hard truth for most readers. You almost certainly will not get to buy Anthropic shares at the IPO price. Those allocations go to large institutions and favored clients first.
The realistic way in for everyday investors is indirect. Owning Amazon or Alphabet gives you a sliver of Anthropic’s upside, since both hold sizable stakes. Once the stock trades publicly, you could buy it like any other listing, though early IPO prices tend to swing hard.
There is a bigger reason to pay attention even if you never buy a single share. A near $1 trillion AI listing sets a price tag that every other AI bet gets measured against.
Not everyone is convinced the math holds. Skeptics have warned for months that AI prices ran ahead of reality. Anthropic carries an unusual risk of its own. The company is locked in a legal fight with the U.S. government after the Pentagon flagged it as a supply-chain risk, reported Fortune.
The listings stacking up this year, with Anthropic, OpenAI, and SpaceX all in motion, add up to what The Daily Upside called a Wall Street “gold rush.” The first one out the gate usually grabs the most attention and the most money.
Anthropic now looks poised to beat OpenAI to the public market, with reports pointing to an October 2026 listing window if the SEC review goes smoothly. Watch the eventual public filing for two numbers above all, the real revenue figures and the cost of all that computing power.
Those will tell you whether this is the deal of the decade or the moment the AI trade finally got ahead of itself.
