OpenAI stock & equity tools

OpenAI is an American artificial intelligence (AI) research organization headquartered in San Francisco, consisting of OpenAI Group PBC, a for-profit public benefit corporation (PBC), partially controlled by OpenAI Foundation, a nonprofit. OpenAI developed the generative pre-trained transformer (GPT) family of large language models, the DALL-E series of text-to-image models, and the Sora series of text-to-video models, which have influenced industry research and commercial applications. Its release of ChatGPT in November 2022 has been credited with catalyzing the AI boom, and widespread interest in generative AI.

Founded 2015 by Sam Altman, Elon Musk (departed 2018), Ilya Sutskever, Greg Brockman and others as a non-profit AI lab, the San Francisco company spun up a capped-profit arm in 2019 and completed its restructure into OpenAI Group PBC in October 2025, with the OpenAI Foundation retaining a 26% stake. Products span GPT-5 and GPT-5.5, o-series reasoning models, ChatGPT consumer and Enterprise, the API, DALL-E, the now-discontinued Sora video generator, and Codex agents. Recent milestones: Altman's five-day ouster in November 2023, Sutskever and Mira Murati exits in 2024, and a $122B March 2026 round co-led by SoftBank, Amazon, and Nvidia at an $852B valuation. Monthly revenue runs about $2B.

Equity comp at OpenAI

• OpenAI does not grant traditional stock options or RSUs. Instead, employees get Profit Participation Units (PPUs), a custom contract OpenAI created for itself. A PPU is a right to a share of OpenAI's future profits, with the total cap on what OpenAI can pay out across all partners set at $250 billion. Because PPUs are not stock and not options, the standard tax math (AMT for ISOs, ordinary-income on RSU vest) does not apply. The calculator on this page is best treated as a rough illustration until OpenAI converts equity to ordinary stock for an eventual IPO.
