Claude Overtakes ChatGPT as Pentagon Backlash Drives App Store Surge
Anthropic's AI assistant hits #1 on iOS as user defections and $380B valuation mark the sharpest consumer momentum shift since the AI boom began.
Anthropic’s Claude app reached the top spot on Apple’s US App Store on Saturday, displacing OpenAI’s ChatGPT in a reversal driven by Pentagon controversy and eleven weeks of accelerating downloads. Claude landed at #1 on Saturday, February 28, pushing ChatGPT to #2 and Google’s Gemini to #4, according to data from CNBC.
The Claude iOS app climbed from #131 in the US on January 30 to bouncing around the top 20 for most of February, before the final surge following Anthropic’s standoff with the Department of Defense over AI safeguards. Free user sign-ups have tripled since November, with Anthropic breaking all-time daily records every day this week, the company confirmed to CNBC. Paying subscribers have more than doubled this year.
The shift follows a turbulent February. On February 27, Anthropic CEO Dario Amodei publicly rejected a Pentagon ultimatum demanding the removal of guardrails preventing mass domestic surveillance and fully autonomous weapons, according to reports compiled by the Windows Forum. President Trump subsequently ordered federal agencies to stop using Anthropic’s technology. Hours later, OpenAI CEO Sam Altman announced an agreement with the Department of War to deploy AI models in classified networks, prompting online debates and defections from ChatGPT users concerned about ethical implications.
The Super Bowl Catalyst
Claude’s ascent predates the Pentagon crisis. The app jumped from #41 to #7 on the US App Store after Anthropic’s Super Bowl commercial, with daily active users increasing 11% and site visits rising 6.5%, according to Blockonomi. US downloads jumped 32% to 148,000 in the three days after the Super Bowl compared to the prior three-day period, per data from Appfigures.
The commercial positioned Claude as an ad-free alternative to ChatGPT, highlighting OpenAI’s recent decision to introduce advertisements into its chatbot. The timing proved prescient—ChatGPT rolled out ads to free users the week after the Super Bowl, just as Anthropic’s ads had warned.
ChatGPT was the most downloaded free iPhone app in the US for all of 2025, jumping from a #4 ranking in 2024 when Temu held the crown. It didn’t crack the top 10 in 2023 despite launching in May that year. Google’s Gemini briefly took the #1 spot in September 2025 after launching its Nano Banana image editing feature, making Claude’s displacement the second time ChatGPT has lost the top ranking since the AI boom began.
Record Funding, Record Revenue
Anthropic raised $30 billion in Series G funding led by GIC and Coatue at a $380 billion post-money valuation, the company announced February 12 according to Anthropic. Run-rate revenue now stands at $14 billion, growing over 10x annually in each of the past three years. The number of customers spending over $100,000 annually grew 7x in the past year.
Claude Code’s annualized revenue reached $2.5 billion, with enterprise users representing more than half of revenue, per CNBC. Business subscriptions have quadrupled since the start of the year. The coding tool’s popularity, alongside Anthropic’s new Cowork productivity offering, contributed to a massive selloff in software stocks that shed around $2 trillion from peak valuations as investors reassessed AI’s disruptive potential.
| Metric | Anthropic | OpenAI |
|---|---|---|
| Valuation | $380B | ~$500B |
| Run-rate revenue | $14B | ~$20B |
| Enterprise focus | ~80% of revenue | Consumer-led |
| Weekly active users | Not disclosed | 800M+ |
| Recent controversy | Pentagon refusal | Pentagon partnership |
Anthropic derives about 80% of its business from enterprises, CEO Dario Amodei told CNBC last month. Around 80% of revenue comes from enterprise and API usage, and while Claude is far less widely used than ChatGPT on a consumer level, it has generated billions from business customers, according to Business of Apps.
Product Velocity Drives Adoption
Anthropic shipped aggressive feature updates in February. Claude Opus 4.6, introduced February 5, brought upgraded coding skills, per Releasebot. Cowork, launched in January as a research preview, brings Claude Code’s agentic capabilities to knowledge work beyond coding, running locally on users’ computers in an isolated VM.
Companies can now connect Claude Cowork to Google Drive, Gmail, DocuSign and FactSet, Anthropic announced February 24 according to CNBC. Claude now works directly inside Excel and PowerPoint, and scheduled tasks let Claude run recurring work automatically at set times, per Reworked.

Consumer vs. Enterprise Trajectories
Claude’s consumer traction lags ChatGPT’s scale. Claude had about 19 million users in Q3 2025, compared to ChatGPT’s 800 million, according to Business of Apps. ChatGPT generated an estimated $238 million in mobile revenue last month on 26 million downloads, per Sensor Tower data. Claude’s iOS app generated an estimated $5 million revenue on 1 million downloads last month.
But enterprise adoption tells a different story. Claude holds about 3.5% of the global AI chatbot market but an estimated 29% share of the AI assistant market among enterprises, according to About Chromebooks. Coding and mathematical tasks make up 34% of all Claude usage, with bug fixing the single most common task at 6% of conversations.
Sacra estimates Anthropic hit $14 billion in annualized revenue in February 2026, up from $9 billion at the end of 2025 and $1 billion at the end of 2024, according to Sacra. Enterprise and startup API calls continue to drive the majority of revenue through pay-per-token pricing.
What to Watch
Sustainability of consumer momentum. App Store rank reflects download velocity and engagement signals but doesn’t disclose retention, DAU/MAU ratios, or revenue conversion from free installs to paying subscribers. Claude’s history suggests challenges: The iOS app saw 157,000 global downloads in its first week in May 2024, compared to ChatGPT’s 480,000 installs in its first five days, and didn’t become a new App Store hit, TechCrunch reported at the time.
Pentagon fallout on enterprise revenue. The DoD dispute could curtail billions in enterprise and government revenue if the supply-chain designation persists or if federal agencies are instructed to stop using Anthropic products. The company has not disclosed how much revenue comes from government contracts.
Competitive response from OpenAI. OpenAI launched GPT-5.3-Codex last week, along with a stand-alone app for Apple computers, in an effort to match Claude Code’s traction. ChatGPT now has over 900 million weekly users, and OpenAI has been responding to Anthropic’s enterprise surge by striking partnerships with consulting firms such as Accenture and Capgemini, according to CNBC.
IPO timing. Anthropic has begun preparations for a potential IPO as soon as 2026, hiring Wilson Sonsini to advise, though Chief Communications Officer Sasha de Marigny said in December there were “no immediate plans to go public”, per Sacra. Both Anthropic and OpenAI are expected to pursue IPOs later in 2026.
The App Store ranking captures a moment, not a trend. Whether Anthropic can convert attention into retention—and whether its Pentagon stance becomes a brand asset or a revenue liability—will determine if this week marks a turning point or a temporary spike in the most expensive customer acquisition race in tech history.
