Employees will have until Dec. 24 to decide if they want to participate in the new tender offer, which has not previously been reported, one of the people said. The deal was spurred by SoftBank billionaire founder and CEO Masayoshi Son, who was persistent in asking for a larger stake in the startup after putting $500 million into OpenAI's last funding round, one of the people said.
The tender offer is not related to OpenAI's potential plans to restructure the firm to a for-profit business, one of the people said.
