OpenAI

Updated 2026-04-06

An AI research company founded in 2015 in San Francisco. It started as a nonprofit and now operates with a hybrid capped-profit structure. Best-known products include the GPT series, ChatGPT, DALL·E, Codex, and Whisper.

Why It Matters

OpenAI changed public perception of AI more than any other single company. ChatGPT, launched in November 2022, became one of the fastest consumer products ever to reach 100 million users. At the same time, OpenAI embodies one of the deepest tensions in the field: safety research on one side, commercial pressure on the other.

Founders and Key Figures

  • Andrej Karpathy — co-founder, later Director of AI at Tesla, then returned to OpenAI
  • Sam Altman — CEO
  • Elon Musk — early co-founder, now building a rival AI company with xAI
  • Greg Brockman, Ilya Sutskever, and others

Products & Models

  • GPT-4 / GPT-4o — flagship language models
  • ChatGPT — the main consumer interface
  • DALL·E — text-to-image generation
  • Codex — code generation, foundational to GitHub Copilot
  • Whisper — open-source speech recognition

Context

The tension between OpenAI’s safety mission and growth pressure has produced several high-profile departures, including Karpathy and Sutskever. The company is a central actor in the current AI race, and a mirror for the deeper question of who controls this technology and for whose benefit.

IPO & Valuation (2026)

On the secondary market, OpenAI is being valued at roughly $850 billion, implying about a 35x revenue multiple on an estimated ~$24 billion in 2025 revenue. Bloomberg reporting from April 2026 suggests that institutional investors are struggling to find buyers for around $600 million in secondary shares. At the same time, Anthropic is running hot, with secondary bids around $600 billion against an official valuation of $300 billion.

Chamath Palihapitiya’s diagnosis is blunt: OpenAI and Anthropic need to go public as quickly as possible, before liquidity in the IPO market gets absorbed by SpaceX. Wait too long, and there may be no appetite left on the table.
