- Demand is strong: the book was about 2x oversubscribed by the end of Tuesday, the first roadshow day, and 6x by the end of Thursday, according to people familiar with the offering.
- The deal aims to raise up to $64.4 billion by selling 825 million shares, valuing Anthropic at up to $1.4 trillion.
- Goldman Sachs and Morgan Stanley are leading the offering, with investor meetings in New York, Boston and San Francisco.
- Reported revenue projections put Anthropic at $52–53 billion in 2026 and $135–137 billion in 2027, with banks estimating $270–280 billion in 2028 — but buy-side forecasts vary widely.
- Investors are asking whether Anthropic can hold its AI lead as Google catches up, and whether Claude can lead beyond coding for knowledge workers.
Demand Builds Fast on the Roadshow
Institutional investors are lining up for Anthropic’s initial public offering faster than they did for SpaceX’s. According to two people familiar with the companies’ offerings, interest in the Anthropic IPO is outpacing the early days of the SpaceX roadshow — a notable comparison, given that SpaceX’s June IPO was one of the largest listings in history.
The book drew about two times the orders for the shares available by the end of Tuesday, the first day of the roadshow, one of the people said. By the end of Thursday, it was six times oversubscribed, another person said. SpaceX’s IPO, by comparison, was two times oversubscribed by the end of its second day of roadshow. Bankers and investors told Reuters that while a single-digit subscription rate would be considered modest for many highly anticipated IPOs, the demand is impressive given the size of the offering — and they expect the order book to grow substantially as the roadshow progresses.
Anthropic and its banks are meeting prospective investors in New York, Boston and San Francisco, one person familiar with the matter said. Goldman Sachs and Morgan Stanley are leading the offering. The roadshow runs through next Wednesday, when the deal is expected to price, with trading to begin about two days later. Details, including demand, could change, the people said, speaking on condition of anonymity. Anthropic declined to comment.
A $1.4 Trillion Valuation Question
The headline figures are among the largest ever attached to a technology listing. Anthropic’s IPO is set to value the company at up to $1.4 trillion, as the AI lab and some of its investors aim to raise up to $64.4 billion by selling 825 million shares.
At the centre of the valuation debate is revenue — specifically, how fast it will keep growing. The key figure underpinning valuation models is Anthropic’s projected 2028 revenue, which banks estimate at around $270 billion to $280 billion and use to apply enterprise-value-to-revenue multiples, according to two people familiar with the projections. For a high-growth company like Anthropic, investors typically give significant weight to future revenue growth.
The nearer-term projections are striking on their own. Some sell-side projections put Anthropic’s revenue at around $52 billion to $53 billion in 2026, rising to $135 billion to $137 billion in 2027, one of the people said. But the range of forecasts is wide: certain buy-side projections run 10% to 15% higher for 2026 and 2027, an investor who has placed an order in the IPO said, while one investor who conducted due diligence but decided not to participate has a more conservative outlook about 30% below the sell-side estimate for 2028.
That spread is not unusual: sell-side estimates tend to track a company’s own projections more closely, while investors build in more optimistic or conservative assumptions. Finding direct peers is also hard — SpaceX and cybersecurity firm CrowdStrike are among the benchmarks being used. The focus on 2028 revenue contrasts with SpaceX, whose valuation case relied on projected 2029 revenue that some investors viewed as particularly aggressive.
Two Questions Investors Keep Asking
During the roadshow, investors are grappling with two fundamental questions: whether Anthropic can maintain its lead as competitors such as Alphabet’s Google rapidly catch up in developing advanced AI models, and whether its Claude chatbot can maintain its lead beyond coding, in the broader market for knowledge workers.
The questions underscore the challenge of valuing a company whose revenue is growing fast but whose long-term position remains uncertain: will the AI industry be dominated by one or two players or support several leaders, and can Anthropic sustain premium pricing if rivals offer comparable models?
Anthropic has kept shipping new Claude models, including the recent Claude Fable 5.2 release, but investors want evidence that the lead extends beyond the coding tasks where Claude first built its reputation. Reliability is part of the same question: a Claude outage in November 2026 left users unable to reach the chatbot, a reminder that even the most popular AI products can stumble in public.
Investors are also weighing the limitations of the information Anthropic is providing. One investor who attended a roadshow meeting said the company had not provided detailed answers to some questions; Anthropic declined to comment. One group meeting also had no conference call for institutional investors to dial in — a departure from standard practice — and Goldman Sachs and Morgan Stanley representatives largely read from prepared remarks rather than soliciting questions, according to an attendee. Morgan Stanley declined to comment; Goldman Sachs did not immediately respond. Some investors remain cautious about an offering at a high valuation amid a broader shakeout in the AI sector.
SpaceX Set the Template — and the Warning
Anthropic’s listing comes on the heels of the high-profile June IPO for Elon Musk’s SpaceX, which raised $75 billion at a nearly $1.75 trillion valuation. SpaceX shares have had a bumpy few months since: the stock last traded at about $140 compared with its IPO price of $135, after falling to about $105 in August.
That track record is both a template and a caution — a giant IPO can price successfully and still wobble in its first months as the market tests whether the valuation holds. “If you have Anthropic come out and then the IPO does poorly, I think that is probably another cautionary sign that investors are getting a little bit more stressed with the AI trade,” said Patrick Ryan, chief investment strategist at Madison Investments.
Nvidia Reports First: The Twin Test
Anthropic does not debut in isolation. The AI trade that has fuelled the rising stock market in recent years — but has lately shown signs of vulnerability — faces twin tests next week: the highly anticipated IPO of Anthropic and quarterly results from beleaguered semiconductor giant Nvidia.
Nvidia reports first, on Tuesday (17 November). Analysts expect earnings growth of 90% on revenue of $109 billion in the company’s fiscal third quarter, according to LSEG data. The stakes are high: Nvidia, whose chips have been at the centre of the AI boom, has seen its market capitalisation drop from about $5.8 trillion in early October to roughly $4 trillion as of Thursday, according to LSEG.
The chipmaker’s week has been dominated by turmoil at the top. Longtime CEO Jensen Huang stepped down on Thursday following revelations about two extramarital affairs, including one involving a suspected Chinese spy, and the controversy has also produced a shareholder lawsuit against Huang. Pressure will now be on interim CEO Colette Kress, previously Nvidia’s chief financial officer, to shore up investor confidence. Given the uncertainty, “if they have less-than-stellar earnings, whatever penalty the market would apply is going to be leveraged down,” said Alex Morris, CEO of F/m Investments.
The backdrop is a market that has been looking the other way. “The market has rose-colored glasses on almost all the risks,” including inflation and the war in Iran, in addition to uncertainty over AI, said Sameer Samana, head of global equities and real assets at the Wells Fargo Investment Institute. Disappointments next week, Samana said, “could finally kind of wake investors up from this ability to look at every glass as half full.”
The AI trade wobbled in recent weeks on doubts over the sustainability of the massive investment spending behind the boom, and concerns flared after Democrats swept the midterm elections, threatening tougher regulations on AI data-center expansion. Despite Nvidia’s woes, many AI-linked stocks steadied, and the S&P 500 was on track for a solid weekly gain — up nearly 11% so far in 2026. Between Nvidia’s results on Tuesday and Anthropic’s expected debut about two days after Wednesday’s pricing, next week will give investors a real-time barometer for sentiment on the AI trade.
