With the rising attention on Codex and open-source models, Claude Code under Anthropic continues to hold a dominant position.

Anthropic is facing increasingly fierce market competition, and customers have doubts about the high prices of its AI tools. However, the leading position of the blockbuster product Claude Code remains difficult to shake. From the end of 2025 to early 2026, many companies are turning to Claude Code, which has encroached on the market share of Microsoft's GitHub Copilot and the AI code tool vendor Cursor in several scenarios. In recent months, as Anthropic switched to a pay-as-you-go billing model, customer usage costs have risen significantly; at the same time, competitor OpenAI has continued to iterate on Codex, greatly enhancing its competitiveness, while open-source model capabilities from China have also made significant progress. Even as major companies actively seek cost control solutions, many still choose to continue using Claude Code.
