Answers are derived from the roster record shown on this page — filing status, last round and confirmed marks. Where the record is silent, the answer says so rather than guessing.
OpenAI is the AI lab behind ChatGPT, GPT-5, and the o-series reasoning models. Originally founded as a non-profit, it now operates a capped-profit subsidiary majority-funded by Microsoft and SoftBank. In March 2026 it closed a record $122B primary round at an $852B post-money valuation (anchored by Amazon, Nvidia, and SoftBank) — the largest private fundraise on record, ranking it among the most valuable private companies in the world.
Step-up compares disclosed post-money valuations. Round / post-money is a financing-size ratio, not an ownership or dilution estimate.
