🇺🇸AI-coding startup Cognition AI raised $2 billion in Series E financing at a $48 billion valuation, led by a16z and Accel.

Cognition AI announced on September 8 that it had raised $2 billion in Series E financing at a $48 billion valuation (已在 E 轮融资中筹集 20 亿美元，估值达到 480 亿美元). The report describes an announced completed fundraising, rather than a proposed financing facility.

New investors a16z and Accel led the round, with existing investors Founders Fund, General Catalyst, and Avenir participating (本轮融资由新投资者 a16z 和 Accel 领投，现有投资者 Founders Fund、General Catalyst 和 Avenir 参投). Cognition said its annualized revenue increased from $492 million to nearly $900 million since its previous financing in May (自 5 月上一轮融资以来，其年化收入已从 4.92 亿美元增至近 9 亿美元).

That revenue figure is explicitly annualized, not reported full-year revenue, and remains a company statement relayed by Telegram. An earlier alert described the amount raised as more than $2 billion (融资额超过 20 亿美元), while the later, fuller report used $2 billion; neither provides share pricing, dilution, investor allocations, or financing conditions.
