Anthropic has chosen its Wall Street lineup. Two days after the company submitted a confidential draft registration statement to the Securities and Exchange Commission, Bloomberg reported on June 3 that Anthropic had selected Morgan Stanley, Goldman Sachs, and JPMorgan Chase to lead its initial public offering. The choice of underwriters is the first concrete step in a process that could produce one of the largest technology IPOs in U.S. history.

The three banks declined to comment on the report, as did Anthropic, which is standard practice before a formal S-1 is filed publicly. More banks are expected to join the syndicate as the deal progresses, which is typical for an offering of this scale. The formal roadshow, which is when a company's management pitches institutional investors directly, is still several months away if the October timeline holds.

The Bank Lineup and What It Signals

Morgan Stanley and Goldman Sachs are the two most coveted lead managers in the U.S. technology IPO market. Over the past decade they have handled some of the largest and most complex listings in the sector, including Arm Holdings in 2023 and several of the sovereign-backed offerings that have come through New York in recent years. Their selection signals that Anthropic intends to run a flagship offering rather than a quiet market debut, one aimed at locking in major institutional allocations from the pension funds, sovereign wealth funds, and long-only asset managers that dominate large-cap IPO books.

JPMorgan's addition broadens that institutional reach further. The bank has particularly strong relationships with corporate treasury desks and the large international investors, including Middle Eastern sovereign funds, several of which already hold positions in Anthropic through its private funding rounds. Having JPMorgan on the deal also means Anthropic has coverage with the largest U.S. commercial banks, which matters when the company is simultaneously pursuing enterprise contracts with major financial institutions.

A Company Running at Full Speed

The IPO preparations are unfolding against the strongest business metrics Anthropic has ever posted. The company's annualized revenue run rate recently crossed $47 billion, driven primarily by enterprise adoption of Claude for coding workflows, agentic AI deployments, and integration with major business platforms. That growth rate, roughly triple what it was eight months ago, is the core of the financial argument Anthropic's bankers will make to institutional investors during the roadshow.

The $65 billion Series H round that closed in late May set a post-money valuation of $965 billion, briefly placing Anthropic ahead of OpenAI as the world's most valuable private technology company. Investors in that round included Google, Amazon, and a range of sovereign wealth funds. The IPO, if it proceeds at the October target, would be the first opportunity for public-market investors to own a direct stake in the company behind Claude.

The October Window and What Comes Next

The typical gap between a confidential SEC filing and a public listing is three to six months. An October date would sit at roughly the four-month mark from the June 1 filing, which is consistent with reports but leaves meaningful room for the timeline to shift based on market conditions or the pace of regulatory review. Anthropic's filing is still in confidential status, meaning the financial disclosures remain private until the company chooses to make the registration statement public, which usually happens three to four weeks before the roadshow begins.

The potential raise of up to $60 billion would put the offering in rarefied company. For reference, Saudi Aramco's 2019 IPO raised $25.6 billion from its public tranche, and Arm Holdings raised $4.9 billion in 2023. Anthropic's deal, if it materializes at that scale, would be substantially larger than either, reflecting both the company's revenue trajectory and the premium investors have been willing to assign to frontier AI labs in private markets.

There is also a competitive dimension that adds urgency. OpenAI has signaled its own plans to go public, and the two companies are running in parallel toward what the industry is treating as a race. The firm that completes its listing first sets the pricing benchmark for the other, and for frontier AI as an asset class more broadly. Anthropic's move to name underwriters just two days after filing its confidential S-1 suggests it is not planning to let that race drag on. The confidential IPO filing and the bank selection together mark the opening chapter of what will be a months-long process, but the pace so far indicates Anthropic is moving with intent.
