> OpenAI has filed confidentially for an IPO, valued at $157 billion in its last private round, as competition from Anthropic, Google DeepMind, and Meta intensifies.

## Key points

- OpenAI has filed confidentially for an IPO with the SEC
- Microsoft has invested approximately $13 billion in OpenAI across multiple rounds
- OpenAI was valued at $157 billion in its most recent private funding round

OpenAI has filed confidentially for an initial public offering, the company confirmed. The move positions it to raise capital from public markets as the generative AI sector continues to draw significant investor interest.

Sam Altman, CEO of OpenAI, has guided the company through rapid growth and several high-profile funding rounds. Microsoft has invested approximately $13 billion in OpenAI across multiple tranches, making it the company's largest backer and a key commercial partner.

## Why an IPO now

OpenAI's most recent private funding round valued the company at $157 billion. A confidential filing allows the company to prepare SEC documentation before releasing a public prospectus, giving it flexibility on timing as market conditions evolve.

The company is also working through a structural transition from its original nonprofit governance model toward a for-profit benefit corporation structure. That shift is relevant to any public offering because investors need clarity on equity rights and governance.

## Competitive landscape

OpenAI competes against Anthropic, backed by Google and Amazon, Google DeepMind, and Meta's AI research division. Each company is racing to build and deploy foundation models at scale. Public market capital would give OpenAI access to a broader investor base and a currency for acquisitions.

ChatGPT, launched in late 2022, remains OpenAI's flagship consumer product and a key driver of enterprise licensing. GPT-4 powers a range of third-party integrations and API customers.

## What it means for B2B buyers

For enterprise customers, an IPO adds a layer of transparency through mandatory disclosures. It also signals long-term commitment to the market. Companies currently evaluating OpenAI's API or enterprise products now have a clearer view of the company's financial direction.
