Bloomberg reports OpenAI’s $11 billion first close

Bloomberg reported on Nov. 6, citing people familiar with the matter, that about $11 billion had been wired to OpenAI as the initial portion of a private funding round associated with a $1.25 trillion valuation. OpenAI declined to comment, according to Bloomberg.

What the funding and valuation figures describe

The reported $11 billion is the initial funding amount; $1.25 trillion is the valuation associated with the financing. They describe different things: funding is capital raised, while valuation is the value attached to the company in the round.

Funding and valuation answer different questions: one is the capital raised, the other is the value attached to the company in the financing.

Bloomberg said the remaining funding was expected in the coming weeks and could bring the round’s total to as much as $20 billion. It also reported that OpenAI was working with investment banks to seek funds from high-net-worth individuals and retail investors.

Investors named in the reports

Bloomberg identified Coatue Management and T. Rowe Price as contributors to the initial close. It separately listed SoftBank Group Corp., Sequoia Capital, Founders Fund and Andreessen Horowitz among investors in the wider round. Reuters also named SoftBank and MGX as participants.

NeoTeo previously covered SoftBank’s final $10 billion tranche in OpenAI, a separate financing development from the November round reported by Bloomberg.

How the reported valuation compares with earlier financing

On Feb. 27, 2026, OpenAI announced $110 billion in new investment at a $730 billion pre-money valuation. The company named $30 billion each from SoftBank and NVIDIA, and $50 billion from Amazon in its announcement. Bloomberg later reported that OpenAI raised $122 billion in a March round at an $852 billion valuation.

Comparing Bloomberg’s reported March and November valuations gives a nominal difference of $398 billion, or about 46.7% of the March figure. That calculation compares reported valuation figures; the November funding amount was about $11 billion.
