OpenAI Reportedly Weighs 2026 Or 2027 IPO Amid Soaring AI Momentum

OpenAI is exploring the possibility of filing with securities regulators as early as the second half of 2026, reported Reuters, citing people familiar with the matter.

In early discussions, the company has reportedly considered targeting a valuation starting around $60 billion, potentially higher.

However, they cautioned that the talks remain preliminary and that both the timing and figures could shift based on the company's growth trajectory and overall market conditions.

Some insiders suggest Chief Financial Officer Sarah Friar has indicated a 2027 listing target, though advisers say it could happen sooner depending on market conditions, the report said.

While the company has not confirmed a timeline, an OpenAI spokesperson told the publication, "An IPO is not our focus … We are building a durable business and advancing our mission so everyone benefits from AGI."

OpenAI did not immediately respond to Benzinga's request for comments.
