**OpenAI stayed independent and kept its U.S. and U.K. headquarters while Anthropic hit $1.75 trillion and led model performance.**

Anthropic closed 2026 with a $1.75 trillion valuation and was judged to have the best AI model at the end of October. OpenAI remained independent and did not sell to another firm. All three firms kept their headquarters in the United States or the United Kingdom.

The valuation figure was $1.75 trillion. It applied to the end of 2026. The measurement was logged on 1 January 2027.

Anthropic's model was judged the best at the end of October 2026. No other company was ranked ahead.

OpenAI was not acquired before 2027. The status was confirmed on 1 January 2027. The company continued operating as an independent entity.

OpenAI, Google Deepmind and Anthropic remained domiciled in the United States or the United Kingdom. No relocation occurred before 2027. The information was logged on 10 November 2026.

## Analysis

Holding both financial and technical leadership may give the firm leverage in partnerships and talent recruitment, especially as rivals vie for comparable capabilities.

OpenAI's decision to stay independent and retain its U.S. and U.K. bases suggests continuity in its strategic direction and research agenda. By avoiding acquisition, the company preserves control over its technology roadmap, which may affect competitive dynamics with other large AI players.

The fact that none of the three major AI firms relocated from the United States or the United Kingdom before 2027 points to a stable regulatory and talent environment in those regions. However, it also leaves open questions about how future policy changes or geopolitical shifts could influence their operational footprints.
