OPENAI SECURES $110 BILLION FUNDING ROUND AT $730 BILLION PRE-MONEY VALUATION TO SCALE AI INFRASTRUCTURE
2026-02-27 07:51
OpenAI announced a $110 billion private funding round at a $730 billion pre-money valuation. Commitments include $50 billion from Amazon, $30 billion from NVIDIA, and $30 billion from SoftBank, with the round open for additional participants.
This follows the company’s March 2025 round of $40 billion at a $300 billion valuation. Proceeds will fund infrastructure expansion, product deployment, and global distribution to address compute and capital requirements for frontier AI models. The raise coincides with OpenAI’s “Scaling AI for Everyone” initiative, which targets broader access for consumers, developers, and enterprises.
Partnership and Compute Commitments
The capital allocation supports dedicated infrastructure builds:
NVIDIA partnership: 3GW of inference capacity and 2GW of training capacity on Vera Rubin systems, building on prior Hopper and Blackwell deployments across multiple providers.
Amazon partnership: Multi-year strategic collaboration including $100 billion in committed AWS compute services (up from a prior $38 billion commitment), 2GW of Tranium-based capacity, custom model development for Amazon products, and a new stateful runtime environment on Bedrock.
Of Amazon’s total investment, $35 billion is contingent on specified milestones including achievement of AGI-level capabilities or an IPO by year-end.
User and Business Metrics
OpenAI reported the following operational figures:
ChatGPT: 900 million weekly active users; more than 50 million paid consumer subscribers. January and February 2026 marked the largest new-subscriber months on record.
Codex: Weekly users tripled to 1.6 million.
Business platform: More than 9 million paying users across startups, enterprises, and governments, focused on engineering, support, finance, sales, and operations workflows.
Strategic and Structural Impact
OpenAI described the current phase as the transition of frontier AI from research to daily global use. The company stated that competitive advantage will derive from the speed of infrastructure scaling and conversion of capacity into reliable products.
Sam Altman, CEO, stated: “We’re pushing the frontier across infrastructure, research, and products to make AI more capable, reliable, and broadly useful. SoftBank, NVIDIA, and Amazon are long-term partners who share our ambition to turn real scientific progress into systems that deliver meaningful benefits for people at global scale.”
The transaction increases the OpenAI Foundation’s stake in the operating group to over $180 billion, providing additional resources for its nonprofit mandate including health and AI resilience initiatives.
The round ranks among the largest private funding events recorded and reflects institutional allocation toward compute-intensive AI commercialization amid rising enterprise and consumer demand.
AI Funding Comparison
Anthropic and xAI remain the next tier but operate at roughly half the valuation and one-quarter to one-third the latest round size. Smaller players such as Perplexity AI, Cohere, and Mistral AI sit at $7-20 billion valuations with funding in the low single-digit billions.
Direct Comparison of Latest Rounds and Valuations (as of February 27, 2026)
OpenAI Latest round: $110 billion (Feb 27, 2026) Valuation: $730 billion pre-money Key backers: Amazon ($50 billion), NVIDIA ($30 billion), SoftBank ($30 billion) Total equity raised (post-2025 rounds): >$150 billion Primary use: 5+ GW dedicated inference and training capacity via Amazon and NVIDIA partnerships.
Anthropic Latest round: $30 billion Series G (Feb 12, 2026) Valuation: $380 billion post-money Key backers: GIC, Coatue, Microsoft, NVIDIA (strategic compute commitments) Total equity raised: $69.1 billion Primary use: Claude model scaling and enterprise API expansion.
xAI Latest round: $20 billion Series E (upsized, Jan 6, 2026) Valuation: $230-250 billion Key backers: Valor Equity Partners, StepStone, Fidelity, Qatar Investment Authority, NVIDIA, Cisco Total equity + debt raised: $45 billion Primary use: Colossus GPU cluster expansion and Grok model training.
OpenAI’s raise is more than 3.5× Anthropic’s and 5.5× xAI’s most recent rounds. Its valuation now exceeds the sum of Anthropic and xAI combined. All three leaders secure strategic capital tied to compute supply from NVIDIA and hyperscalers, but OpenAI’s Amazon commitment alone ($100 billion multi-year cloud + $50 billion equity) dwarfs rivals’ infrastructure deals.
Big Tech capex provides indirect context: Amazon, Google, Microsoft, and Meta are collectively guiding $650-700 billion in AI-related spend for 2026. This supports the private labs via cloud credits and partnerships but does not replace direct equity raises for model developers.
The funding gap reflects differences in compute scale required for frontier training, user metrics (OpenAI: 900 million weekly ChatGPT users; Anthropic enterprise revenue run-rate ~$14 billion annualized), and investor confidence in near-term commercialization paths. No other private AI company approaches this capital concentration in 2026.
