Anthropic has opened its books to public-market investors, revealing rapid revenue growth alongside the enormous costs of building and operating its Claude artificial intelligence models. The company filed its registration statement with the US Securities and Exchange Commission on October 26, bringing its planned initial public offering closer to reality.
The Bloomberg report on Anthropic’s IPO filing comes as investors scrutinize whether leading AI developers can turn rising demand into sustainable profits. Anthropic intends to list its Class A shares on the Nasdaq Global Select Market under the ticker ANT, according to its official IPO announcement. The company has not yet determined the number of shares it will sell or the offering’s price range.
Anthropic’s Revenue Surges as AI Development Costs Mount
Anthropic generated $16.3 billion in revenue during the first half of 2026, sharply above the $1.1 billion reported for the same period a year earlier, according to disclosures reported by Reuters. The company also told prospective investors that third-quarter revenue reached $16.8 billion, up about 45% from the previous quarter.
The growth reflects increasing demand for Claude and Anthropic’s coding and workplace AI products. However, the company’s financial disclosures show that expansion comes with substantial expenses and financing risks.
Anthropic reported a net loss of $80.7 billion for the first half of 2026, Reuters reported. A large portion of the loss was linked to accounting adjustments involving financing instruments, rather than cash spent directly on day-to-day operations. The headline figure therefore needs to be distinguished from the company’s underlying operating performance, although it does not by itself establish that the business is profitable.
The figures add to questions surrounding the economics of advanced AI. Anthropic must pay for computing capacity to train and operate its models while investing in new systems to compete with rivals such as OpenAI. Its results are also relevant to investors assessing the broader AI stock valuation debate.
Anthropic IPO Valuation and Infrastructure Commitments Face Scrutiny
Anthropic’s public filing arrives after reports of a potential valuation near $2 trillion. Reuters reported on October 26 that some current and prospective investors had discussed a figure closer to $1.5 trillion after receiving updated financial information. Neither amount is a confirmed IPO valuation, and the final terms remain undecided.
The company was valued at $965 billion in a funding round in May, according to Reuters. Its public-market debut would give investors a more direct way to assess the financial performance of a leading AI developer, while placing greater scrutiny on its costs and long-term capital requirements.
Computing infrastructure is a major part of that equation. Anthropic depends on technology partners including Amazon and Google for cloud services and computing capacity. These relationships help support Claude’s growth, but they also expose the company to the cost and availability of the infrastructure required to develop and operate advanced models.
Anthropic has also been negotiating additional computing capacity with infrastructure provider Nscale, including a potential second deal worth about $45 billion, as previously reported. The discussions remain separate from finalized agreements and should not be treated as a completed transaction.
The IPO could become an important test of investor appetite for capital-intensive AI businesses. The market will be weighing Anthropic’s fast-growing revenue against its losses, infrastructure needs and the uncertainty surrounding future returns. Similar questions have emerged around OpenAI’s reported revenue trajectory and the financing required to support the wider AI buildout.
Anthropic has not yet set its share price or disclosed the number of shares to be offered. Its registration statement must also become effective before the securities can be sold. Until the offering terms are finalized, any valuation attached to the IPO remains an estimate rather than a confirmed price.
