OpenAI's latest publicly disclosed primary financing record is a USD 122,000,000,000 Financing round dated March 31, 2026. The event is shown on the company page using the event date—not the date Captables published this historical profile.
Amazon ($50B), SoftBank ($30B), NVIDIA ($30B), co-leads include Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, T. Rowe Price are identified as lead investors.
The preceding primary records in the ledger are $110B Mega- Round dated February 27, 2026; $8.3B Series F (extension) dated August 1, 2025; $40B Series F dated March 31, 2025. These entries describe disclosed company financings; they do not include every secondary trade, employee tender, valuation mark or rumored transaction unless those events are separately labeled in the company ledger.
OpenAI is ranked number 2 in the Captables Private 100 source universe. It operates in Artificial Intelligence and is based in United States. Its $840.0B ranking value is a third-party snapshot and should not be treated as a current executable share price or as the valuation for this round.
The round is currently supported by a public financing-database entry rather than an issuer filing, so Captables labels it as database-listed evidence. This page is a public-source reconstruction, not the issuer's stock ledger or legal capitalization table; undisclosed terms remain undisclosed and readers can submit stronger evidence for editorial review.
