What happened
Anthropic, the maker of the Claude chatbot, filed paperwork for an initial public offering (IPO) on Monday, listing its shares on the Nasdaq under the ticker symbol 'ANT'. According to Wired, the company disclosed revenue of more than $16 billion and a net loss of $80.7 million in the first half of 2026, compared with a $13 billion loss during the same period last year.
The IPO filing comes amid an escalating feud between Anthropic and rival OpenAI over a Pentagon deal. Anthropic President Daniela Amodei questioned OpenAI's decision to strike a deal with the Pentagon, asking whether it was a 'really principled stand' or an 'opportunistic moment' during a joint interview with her brother, Anthropic CEO Dario Amodei, conducted by biographer Walter Isaacson for his podcast 'The Builders'.
The dispute erupted in February when Anthropic refused to abandon restrictions on using its AI models for mass domestic surveillance and fully autonomous lethal weapons. Pentagon officials insisted that defense contractors must permit their technology to be deployed for 'all lawful uses'. OpenAI later reached its own agreement with the Pentagon, permitting broad lawful uses of its technology while retaining safeguards governing surveillance and human control of weapons systems.
Why it matters
The escalating rivalry between Anthropic and OpenAI has significant implications for the AI industry, particularly in the realm of military AI. Anthropic's refusal to permit fully autonomous weapons and mass domestic surveillance has put it at odds with the Pentagon, while OpenAI's deal with the Pentagon has drawn criticism from Anthropic's leadership.
The dispute also highlights the ethical considerations surrounding the use of AI in military applications. Anthropic CEO Dario Amodei warned that allowing one person to control an army of a million AI-powered robots or drones could undermine democracy, as AI models do not provide the same protections as human soldiers.
For investors, the IPO filing provides a glimpse into Anthropic's financial performance, with the company reporting a significant increase in revenue and a decrease in net loss compared to the previous year. However, the ongoing litigation with the Pentagon poses a business risk, as it could undermine sales to government agencies and federal contractors.

Context
The feud between Anthropic and OpenAI dates back to 2021, when Dario and Daniela Amodei left OpenAI and founded Anthropic amid disagreements over safety, corporate governance, and the company's increasingly commercial direction.
The dispute turned especially nasty during the Pentagon showdown in March, when Dario reportedly blasted OpenAI's account of its military deal as 'straight up lies' and 'safety theater' in a leaked internal message. He later apologized for the tone of his remarks but stood by Anthropic's position.
Anthropic challenged the administration's actions in federal court, winning a favorable ruling in California in August before a separate federal appeals court in Washington upheld a Pentagon exclusion the following month. The company sought a rehearing of the latter decision earlier this month.
