OpenAI’s $1.5 trillion valuation is now the subject of active talks with investors, coming just days after CEO Sam Altman ruled out taking the company public in 2026. The talks come amid rising safety concerns in the AI industry — concerns sharpened by OpenAI’s own recent AI agent security incidents — cited by Altman as the reason. Nothing is finalized, and OpenAI itself has declined to comment on specifics, but multiple outlets — including the New York Times, Wall Street Journal, and Forbes — are reporting the same broad shape of the story from people familiar with the discussions.
What OpenAI Is Considering
According to Forbes, investors recently approached OpenAI with an offer to invest at a $1.2 trillion valuation. OpenAI is said to be pushing back, arguing the company is worth at least $1.5 trillion given accelerating demand for its coding tool Codex and its newer models, GPT-6 Astra and GPT-5.6 Sol. If the round closes anywhere near that figure, it would make OpenAI the world’s most valuable privately held company, easily surpassing its March valuation.
The people familiar with the talks stressed that discussions are still early and plans could change. This is not a formal fundraising process yet, and it’s worth reading these figures as opening positions rather than a settled outcome.
How This Compares to OpenAI’s Funding History
| Round | Valuation | When |
| March 2026 raise | $730B pre-money / $852B after new capital | Completed, $122B raised |
| Investor proposal | $1.2 trillion | Recently offered to OpenAI |
| OpenAI’s ask | $1.5 trillion | Under discussion, nothing finalized |
OpenAI has raised more than $180 billion since it was founded in 2015. Its most recent completed round, in March, brought in $122 billion — a record for Silicon Valley — at a valuation of $852 billion after the new capital was added. A round anywhere near $1.5 trillion would roughly double that figure in a matter of months.
Why the IPO Got Ruled Out for 2026
Altman addressed the IPO question directly in an interview with Fortune on September 12, calling this an “ill-advised moment” to go public and citing growing concern over AI’s risks. According to reporting from The Next Web, OpenAI CFO Sarah Friar has told staff the company expects to be public by 2027, though she noted it could happen sooner if the business “continues to inflect.” That’s a target and an internal expectation, not a commitment OpenAI has made publicly as a fixed date.
Altman has also said the company might need to make decisions that don’t serve near-term shareholder interests — including potentially pausing development of frontier models to allow more room for safety work. Whether that would actually happen, or how it would square with a $1.5 trillion valuation push, isn’t yet clear from anything OpenAI has said publicly.
The Business Case Behind the Number
OpenAI’s argument for a higher valuation rests on real growth, not just narrative. The company’s annualized revenue topped $40 billion in August — roughly double where it stood at the end of last year — driven in part by rising enterprise use of Codex and adoption of its newer models. Whether investors accept OpenAI’s $1.5 trillion figure over the $1.2 trillion they initially proposed is the open question the next few weeks of negotiation will settle.
How This Fits the Broader AI Slowdown Debate
This funding news lands in the middle of a moment we’ve been covering closely: AI leaders including Altman, Anthropic’s Dario Amodei, and Elon Musk have all recently called for slowing the pace of AI development, even as their companies keep racing to build bigger models and raise bigger rounds. We wrote about why AI leaders are suddenly talking about slowing down AI earlier this week — and this valuation push is a useful real-world test of how much that rhetoric actually shapes company behavior versus how much it coexists alongside business as usual.
It’s not a contradiction, exactly — a company can genuinely believe in the need for more safety guardrails while still raising capital at an aggressive valuation. But it’s a tension worth naming rather than smoothing over, especially given how directly Altman has tied the IPO delay to AI safety concerns.
What This Means Going Forward
None of this changes anything for the average ChatGPT or Codex user today — though it’s part of a broader pattern of AI assistants gaining more autonomy, from handling files to acting on permissions without always asking first. But it’s worth watching for a few reasons: a $1.5 trillion valuation would set a new benchmark for the entire AI industry, likely affecting how investors price competitors like Anthropic, which has also filed for an IPO. It would also give OpenAI a much larger war chest heading into 2027, right as the safety and regulation conversation is intensifying in Washington.
Nothing here is settled yet — not the valuation, not the IPO timeline, and not how the safety-versus-growth tension resolves. But the two threads are worth holding side by side: a company raising money at a pace few businesses ever have, at the same time its leadership is talking publicly about slowing down. How that tension plays out is likely to say a lot about where the AI industry heads next.
| Editor’s Observation
What stands out to me here isn’t the number itself — valuations at this scale have stopped being shocking. It’s the gap between the slowdown language and the fundraising pace, worth watching rather than judging outright. Companies can hold both positions sincerely at once; it’s still worth readers noticing when they do. |
FAQs
Is OpenAI actually going public this year?
No. Sam Altman ruled out a 2026 IPO on September 12, citing AI safety concerns. CFO Sarah Friar has pointed to 2027 as an internal target, but OpenAI hasn’t made that a fixed public commitment.
Is the $1.5 trillion valuation confirmed?
No. This is an early-stage discussion, not a completed deal. Investors reportedly proposed $1.2 trillion; OpenAI is said to be pushing for $1.5 trillion. Multiple outlets caution that plans could still change.
How does this compare to OpenAI’s last valuation?
OpenAI was valued at $852 billion after its March 2026 round, which raised $122 billion. A round near $1.5 trillion would roughly double that figure.
