Claude hits No. 1 on the App Store as ChatGPT users back Anthropic over Pentagon stance

Claude hits No. 1 on the App Store

Anthropic’s Claude AI surged past ChatGPT to claim the top spot on Apple’s US App Store. The rise comes amid growing dissatisfaction from ChatGPT users over OpenAI’s recent agreement with the Pentagon, highlighting how ethical concerns can influence user choices.

The move also pushed Claude to the top of productivity apps, competing alongside ChatGPT, Google’s Gemini, and xAI’s Grok. Daily signups and active users have sharply increased, marking a milestone in the ongoing chatbot wars.

Users defect from ChatGPT

Many ChatGPT users publicly announced cancellations, sharing screenshots on social media to document their switch. Celebrities like Katy Perry highlighted Claude’s $20-per-month Pro plan, symbolising a growing public interest in ethical AI practices.

Reddit threads show users encouraging each other to cancel ChatGPT subscriptions, fueling a broader movement known as #CancelChatGPT. The user migration emphasises that decisions around AI ethics can have tangible market effects.

Anthropic stands firm against Pentagon use

Anthropic CEO Dario Amodei refused Pentagon demands to deploy Claude freely, citing ethical concerns over mass surveillance and autonomous weapons. This hard stance led President Donald Trump to order federal agencies to phase out Anthropic’s technology.

The refusal reflects Anthropic’s commitment to keeping human oversight central. By drawing clear boundaries, the company has gained positive public attention despite losing some government contracts.

OpenAI reaches Pentagon agreement

Sam Altman confirmed that OpenAI secured an agreement with the U.S. Department of Defense, allowing its models, including ChatGPT, to be used in classified Defense Department systems. The deal emphasises human oversight and explicitly bars use for mass domestic surveillance and fully autonomous weapons, but some users remain uneasy.

Critics argue that legal and oversight gaps could still allow indirect impacts on U.S. citizens. The agreement demonstrates how AI deployment intersects with national security and public trust, fueling debates about corporate ethics.

Record growth for Claude

Anthropic reported over 60% growth in free active users since the start of the year, with daily signups quadrupling. Paid subscribers on Pro and Max plans more than doubled, showing that the chatbot’s popularity is rising fast.

Every day last week set all-time records for Claude sign-ups, according to Anthropic. The growth underscores how public perception of ethical AI decisions can translate into concrete market success.

ChatGPT still dominates overall

Despite Claude’s surge, ChatGPT continues to report around 900 million weekly active users. OpenAI’s widespread adoption ensures that it remains the dominant AI platform, especially for enterprise and global users.

The gap highlights that while ethical stances can influence some users, scale and entrenched adoption remain powerful forces in AI market dynamics.

Little-known fact: As of early 2026, Claude has about 18.9 million monthly active users worldwide, with roughly 7.38 million using the mobile app each month, showing strong global engagement across web and mobile platforms.

Social media amplifies the trend

Platforms like X and Reddit have amplified the debate, with users sharing screenshots of Claude sign-ups and ChatGPT cancellations. The visibility reinforces public pressure and shapes how AI companies respond to user concerns.

Many users expressed that OpenAI’s Pentagon deal “crossed a line,” while others joked about Anthropic’s PR win. This dynamic shows how social perception can affect adoption and brand reputation in real time.

AI ethics influence adoption

Users are increasingly considering ethical stances when choosing AI platforms. Anthropic’s refusal to allow unrestricted Pentagon access gave it a clear moral positioning, attracting ethically-minded users away from ChatGPT.

The trend demonstrates that AI performance alone may not be enough. Ethical principles, transparency, and user trust are becoming equally important in the competitive AI landscape.

Enterprise focus for Anthropic

CEO Dario Amodei is guiding Anthropic toward enterprise users while maintaining ethical safeguards. The company’s strategy balances growth with responsible AI deployment, targeting organisations that value safe and compliant AI.

By focusing on enterprise adoption, Anthropic aims to build long-term relationships with users who prioritise both performance and ethics, ensuring sustainable growth in a competitive market.

Little-known fact: In February 2026, Anthropic reported that Claude’s run‑rate revenue reached $14  billion, up sharply from roughly $1  billion USD at the end of 2024.

Ethics drive AI adoption

Claude’s climb to No. 1 highlights the growing importance of ethics in AI. Users are not only looking for performance and features, but also for how companies handle government agreements, privacy, and responsible AI deployment.

Anthropic’s clear moral stance has resonated with users frustrated by OpenAI’s Pentagon deal. Public perception, media coverage, and ethical commitments are shaping the next generation of AI adoption.
