How much has OpenAI raised?

OpenAI has raised roughly $180B in disclosed capital since its 2015 founding, spanning equity rounds and debt facilities. That figure includes the ~$1B pledged at founding, Microsoft's multi-billion-dollar investments (2019-2023, ~$13B cumulative), the $6.6B 2024 round, the $40B 2025 SoftBank round, and the $122B 2026 round.

Not all of that is paid-in equity. OpenAI also arranged a $4B revolving credit facility from banks (JPMorgan, Goldman Sachs, Morgan Stanley, Citi and others) in October 2024, and SoftBank's commitments have been structured in tranches rather than paid up front. The headline 'raised' number therefore blends committed equity, drawn capital, and debt capacity, which is why tracker totals cluster around $180B rather than a single clean equity figure.

SoftBank is now the defining investor, having led both the $40B 2025 round and co-led the $122B 2026 round, betting much of its balance sheet on OpenAI and the Stargate compute program. Microsoft remains the foundational strategic partner — its early $1B (2019) and reported ~$10B (2023) bought Azure exclusivity and a large equity stake (about 27% of OpenAI Group after the 2025 restructuring) — while Nvidia and Amazon joined as both investors and compute/hardware partners in the 2026 round.

Financial and crossover backers include Thrive Capital (which led the 2024 round), Andreessen Horowitz (co-lead in 2026), Sequoia, Founders Fund, Tiger Global, Khosla Ventures, Altimeter, Fidelity, MGX, TPG, and T. Rowe Price-advised accounts. The investor base skews toward megafunds and strategics able to write multi-billion-dollar checks into a capital-hungry compute business, with even retail money (~$3B) entering the 2026 round.

OpenAI's valuation has climbed roughly 30x in three years — from ~$29B in early 2023 to $157B (Oct 2024), $300B (Mar 2025), ~$500B on a secondary (Oct 2025), and $852B (Mar 2026). The driver is revenue that scaled from ~$3.7B (2024) to ~$13B (2025) to ~$25B annualized (early 2026), plus ChatGPT's growth to ~900M weekly users.

The risk side is equally large. Gross margin compressed from ~40% (2024) to ~33% (2025) as inference costs roughly quadrupled (about $8.4B in 2025, ~$14.1B projected in 2026), and projected cash burn runs to roughly $27B in 2026 and ~$63B in 2027, with cash-flow breakeven not expected until around 2030. Some investors and even CFO Sarah Friar have publicly cautioned that revenue growth must keep pace with the company's enormous compute commitments — a tension that shaped the IPO debate.

OpenAI is not profitable. It operates at a substantial loss driven by training and inference compute — one analysis pegged its Q1 2026 operating margin at roughly negative 122% — and cash-flow breakeven is not expected until around 2030. Revenue is growing fast, but so is spending on the Stargate data-center build-out.

On June 8, 2026 OpenAI confidentially filed an S-1 with the SEC, with Goldman Sachs and Morgan Stanley leading and a target valuation of roughly $730B-$1T, eyeing a public listing in late 2026. The listing has been internally contested — Sam Altman pushed for speed while CFO Sarah Friar urged caution about whether revenue can support the company's massive server commitments.

A company sitting on a $122B round and ~$180B of lifetime capital has real budget — but it spends most of it on compute, data centers, and research talent, not on discretionary software. The biggest new budgets the raise funds are infrastructure (chips, power, data centers), security, finance/IPO-readiness, and headcount tooling for a ~4,500-person org scaling fast.

Procurement is maturing rapidly: with a CFO from Square/Nextdoor (Sarah Friar) and an imminent public listing, OpenAI is professionalizing finance, compliance, and vendor governance. If you sell into them, expect formal procurement and security review, frame ROI against their margin and inference-cost pressure, and target the functions the raise actually feeds — infra, security, finance, GTM, and developer/HR tooling — rather than pitching core AI capabilities they build in-house.
