Anysphere's AI coding assistant, Cursor, has experienced rapid growth, prompting the company to reject acquisition offers from OpenAI. Cursor's annual recurring revenue has reached approximately $300 million, doubling every two months. Despite interest from OpenAI, Anysphere aims to remain independent and is in discussions to raise capital at a $10 billion valuation. OpenAI is now focusing on acquiring Windsurf, another fast-growing coding startup with a $3 billion offer. This strategic shift comes as OpenAI faces increasing competition from other AI model developers.
