OpenAI investors have approached the company about a new funding round

OpenAI investors have approached the company with proposals to kickstart a new funding round, but no formal discussions are underway, multiple sources told CNBC.

Investors have floated a $1.2 trillion valuation to OpenAI, and some have positioned the potential new funding round as a way for employees to sell stock, according to the people, who asked not to be named in order to discuss nonpublic information.

OpenAI, which raised $122 billion at a $852 billion valuation in March, is not currently engaged in conversations, the people said.

OpenAI declined to comment. The Financial Times was first to report the potential round.
