Anthropic gains ground

Anthropic is winning more corporate artificial intelligence budgets, narrowing a gap with OpenAI that looked much wider a year ago. (ft.com) Menlo Ventures said in July 2025 that Anthropic had reached 32% of enterprise large language model market share, ahead of OpenAI at 25%, as enterprise spending on those models rose to $8.4 billion from $3.5 billion six months earlier. Menlo’s broader 2025 enterprise survey later put Anthropic at 40% of enterprise model spend, up from 24% a year earlier. (menlovc.com) The Financial Times reported on April 9, 2026 that Anthropic’s recent gains have been strongest in coding and business work, where companies are buying tools for software development, document drafting, and internal analysis. That is the part of the market where contracts are larger and usage is stickier than consumer chatbot subscriptions. (ft.com) Anthropic has spent the past year packaging Claude for those buyers instead of selling only a standalone chatbot. In August 2025, it added Claude Code and new admin controls to Team and Enterprise plans, giving companies centralized billing, visibility, and policy controls. (anthropic.com) On April 10, 2026, Anthropic rolled out Claude for Word in beta, pushing Claude directly into Microsoft Word for drafting, editing, and review. Anthropic’s product page says the tool preserves formatting and shows every edit as a tracked change that a user can accept or reject. (claude.com) Business Insider reported that Anthropic is pitching Claude for Word to lawyers and other document-heavy teams, with examples focused on contract review, comment handling, and long-form drafting inside Word rather than in a separate chat window. That puts Anthropic closer to the daily workflow where legal and compliance teams already spend their time. (businessinsider.com) OpenAI still has a larger overall business footprint by customer count. OpenAI said in November 2025 that more than 1 million business customers were paying to use its products directly through ChatGPT for work or its developer platform. (openai.com) OpenAI also keeps a broad office and workplace push of its own through ChatGPT Business, ChatGPT Enterprise, and its developer tools. Its business pricing page says Business starts at $20 per user per month on annual billing, while Enterprise is sold through custom pricing. (openai.com) Anthropic’s latest numbers show why investors and rivals are watching the enterprise race so closely. MarketWatch, citing company figures reported on April 7, said Anthropic’s annualized revenue had climbed to $30 billion, up from about $9 billion at the end of 2025. (morningstar.com) The contest now looks less like a single chatbot popularity race and more like a fight over workplace software. Anthropic’s bet is that coding seats, legal review, and document workflows will keep pulling Claude deeper into the companies that pay the biggest bills. (ft.com)
