Anthropic Investors Target $2 Trillion Valuation in October IPO Push

Anthropic's major backers are pushing for a public market debut as early as October at a valuation of at least $2 trillion, a figure that would eclipse SpaceX's $1.77 trillion June 2026 listing to become the largest initial public offering in history, according to Yahoo Finance.

The Claude maker filed a confidential S-1 registration statement with the Securities and Exchange Commission on June 1, 2026, formally launching the IPO process. Since that filing, the company's revenue metrics have continued to improve at a pace that is shifting investor expectations upward from the $965 billion post-money valuation set by the company's most recent funding round.

Revenue growth driving the $2 trillion target

Anthropic's annualized revenue run rate surpassed $65 billion in 2026, more than seven times higher than its exit rate at the end of 2025, according to TechCrunch. That trajectory, if sustained into 2027, would place the Claude business among the fastest-scaling enterprise software operations on record and forms the core justification for the $2 trillion target. At $65 billion in annualized revenue, a $2 trillion market capitalization would imply a forward revenue multiple of roughly 30 times, a premium consistent with the highest-growth software companies at peak expansion phases.

By comparison, SpaceX's current market capitalization of approximately $1.81 trillion reflects a hardware and aerospace business with a materially different cost structure. The higher multiple Anthropic investors are seeking reflects both the AI platform's revenue growth and the higher margins typically attributed to software versus manufacturing.

From $965 billion to $2 trillion: the valuation path

The $965 billion Series H valuation, set in May 2026 through a $65 billion round led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, itself represented a dramatic step up from the $183 billion Series F valuation reported by Yahoo Finance. Reaching $2 trillion at IPO would require the public markets to price in continued hypergrowth and a credible long-term path to operating leverage.

Amazon and Google parent Alphabet are both major investors and committed cloud infrastructure partners. The two companies have pledged billions in cloud compute capacity to Anthropic, agreements that provide the company with the infrastructure to train and serve its Claude model family at scale and that underpin the revenue visibility investors point to when justifying the elevated valuation target.

What comes next

An October 2026 IPO would require Anthropic to transition from a confidential S-1 to a public filing, complete its SEC review period, and conduct an institutional roadshow, a process that typically runs six to eight weeks once the public registration becomes effective. Anthropic has not publicly confirmed an October target, and the final schedule will depend on SEC review timing, market conditions for high-multiple technology names, and board approval.

If the offering proceeds at $2 trillion, the IPO would surpass SpaceX by more than $200 billion and would represent the largest listing in global market history. Institutional investors who receive allocations in the IPO and retail investors who buy in the open market on day one would be subject to standard post-IPO lockup periods for pre-IPO shareholders, typically 180 days from the first trading date.
