Anthropic's $64 Billion IPO Draws Six Times Oversubscription

Anthropic's $64 billion initial public offering was six times oversubscribed by the third day of its roadshow, Reuters reported on November 13, 2026. The demand outpaced institutional interest in the early days of SpaceX's roadshow, according to people familiar with the offering.

Orders reached about twice the shares available by the end of the roadshow's first day, launched November 10, 2026. Two days later the book stood at six times coverage. Bankers and investors called the early demand impressive for an offering of this size and said they expected the order book to grow substantially. The sources cautioned that demand and other IPO details could change. Anthropic declined to comment on the reported demand.

The roadshow runs through November 18, 2026, when the deal is expected to price. Anthropic and its investment banks are meeting prospective investors in New York, Boston and San Francisco.

What are the offering's terms?

The company proposed selling 825 million Class A shares at an expected $70 to $78 per share. Underwriters hold a 30-day option for up to 123.75 million additional shares. Anthropic has applied to list on the Nasdaq Global Select Market. The registration had not yet become effective when the terms were announced.

Can Claude hold its premium pricing?

Reuters reported that investors are testing two parts of Anthropic's investment case: its ability to stay ahead in advanced AI models as Alphabet's Google and other rivals close the gap, and Claude's potential to expand from coding into broader knowledge-work uses. The debate extends to how many companies the market can sustain at the top and whether comparable rival models could erode Anthropic's premium pricing.

Disclosure gaps have added friction. One investor who attended a roadshow meeting said Anthropic had not provided detailed answers to some questions. That limited disclosure has fed caution among some investors about a high-valuation offering during a broader shakeout in the AI sector.

One attendee said a group meeting lacked a conference call for institutional investors to dial in and ask questions — a departure from standard practice — and that Goldman Sachs and Morgan Stanley representatives largely read prepared remarks rather than solicit questions. Morgan Stanley declined to comment. Goldman Sachs did not immediately respond.

What revenue do the valuation models assume?

Banks are anchoring their models to projected 2028 revenue of approximately $270 billion to $280 billion, according to two people familiar with the projections. The models apply enterprise-value-to-revenue multiples, which compare a company's value with expected sales, to produce valuation estimates.

One person familiar with the projections cited sell-side projections of roughly $52 billion to $53 billion in 2026 revenue and $135 billion to $137 billion in 2027. Separately, an investor who placed an order in the IPO said certain buy-side forecasts ran 10% to 15% higher for those years. The spread cuts both ways: an investor who conducted due diligence but decided not to participate used a 2028 outlook about 30% below the sell-side estimate.

SpaceX and the cybersecurity company CrowdStrike serve as valuation benchmarks, one person familiar with the projections said. The Anthropic models focus on 2028 revenue, whereas SpaceX's case relied on projected 2029 revenue that some investors viewed as particularly aggressive.

What happens on November 18?

The early subscription figures establish strong demand for the shares. The unresolved question is whether Claude can maintain its competitive position and premium pricing strongly enough to support the revenue assumptions through 2028. That question gets its first market answer when the deal prices on November 18, and a fuller one when the shares trade on Nasdaq.
