**Anthropic also saw its valuation rise to $1.75 trillion while OpenAI confirmed it would not be sold before 2027.**

Anthropic emerged as the leader in AI model performance at the close of 2026. Its valuation climbed to $1.75 trillion by December 31. OpenAI announced it would not be acquired before 2027. Neither OpenAI, Google Deepmind nor Anthropic moved their corporate domicile from the United States or United Kingdom during 2026.

The milestone was reached without any change in the company's headquarters location.

Independent benchmarking placed Anthropic's models ahead of those from OpenAI, Google and other competitors.

OpenAI's board confirmed on 1 January that no acquisition deal would close before 2027. The decision was communicated as a definitive stance rather than a tentative plan. The announcement came as the sector evaluated consolidation possibilities.

A separate resolution on 10 November recorded that OpenAI, Google Deepmind and Anthropic would remain domiciled in the United States or United Kingdom through 2027. The companies cited regulatory and operational considerations for staying in their current jurisdictions. No relocation filings were submitted during the reporting period.

## Analysis

Anthropic's ascent to the top of model performance rankings indicates a shift in competitive dynamics within the AI sector. By surpassing established players, the firm may attract more research talent and partnership opportunities, though continued leadership will depend on sustaining innovation cycles.

OpenAI's decision to forego a sale and to keep its domicile unchanged suggests a preference for operational stability amid an environment of potential consolidation. This stance may limit near-term merger activity but also leaves open the possibility of strategic partnerships, while regulatory pressures could influence future corporate structuring.
