Neither Stripe nor OpenRouter will confirm the deal reported between them

Bloomberg reported on 16 August that Stripe has finalised an agreement to buy OpenRouter for more than $7 billion. The story ran under a joint byline from Yazhou Sun, Natasha Mascarenhas and Paige Smith, is carried by Fortune, and is attributed to people with knowledge of the talks. It says the price could still move.

Three days later, neither company has said anything. Stripe’s newsroom index is current and carries no acquisition item. Its blog runs to 17 August with nothing on it. OpenRouter’s blog is also current to 17 August, the day after the report, and carries no post about being bought. Asked directly, a Stripe spokesperson said the firm does not comment on rumours or speculation. OpenRouter declined to comment.

That is worth stating up front, because the deal has been written up widely as a settled fact. What exists is one report, from a credible newsroom, that both parties have pointedly declined to confirm.

The number has been going down

The reported price has moved once already, in the direction people rarely mention. Fortune’s account notes that the Wall Street Journal previously reported Stripe in talks to buy OpenRouter for about $10 billion, which is the report we covered in July. The figure now attached to a finalised agreement is more than $7 billion. Whatever happened between those two reports took roughly $3 billion off the top.

Set against the last valuation OpenRouter is reported to have carried, the direction is the other way. The company raised $113 million in a Series B announced on 28 May, led by CapitalG, Alphabet’s independent growth fund, with participation from NVIDIA’s venture arm NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures and Databricks Ventures. It has raised more than $150 million in total. Reports put the valuation at that round near $1.3 billion, though neither company has stated it.

What Stripe would actually be buying

OpenRouter sits between a developer and the model providers, taking one request and routing it to whichever model suits the job and the budget. The scale figures in most coverage are OpenRouter’s May numbers: 8 million-plus developers across 400-plus models, with weekly token volume up fivefold in six months, from 5 trillion to 25 trillion, and a stated run rate of over a quadrillion tokens for the year.

The company’s own homepage on 19 August is further along than that. It claims 10 million-plus global users, 500-plus models, 80-plus providers and more than 200 trillion tokens a month, with 250,000-plus applications built on it reaching 4.2 million-plus end users.

They were already working together

The commercial relationship is documented, by Stripe, in its own newsroom. On 29 January it published OpenRouter as a customer, describing how the company uses Stripe Invoicing, Stripe Tax and Radar for Fraud Teams to run its billing, tax compliance and fraud screening, and takes payments globally across cards and local methods including Alipay, WeChat Pay, Amazon Pay, Cash App and Google Pay.

Alex Atallah, OpenRouter’s co-founder and chief executive, is quoted on that page: “Stripe handles payment complexity in an elegant way so we can focus on making AI models accessible and high-quality for developers everywhere.”

Buying a customer you already process payments for is a particular kind of acquisition. Stripe would know OpenRouter’s gross volumes, its growth curve and its churn from its own systems before making an offer, which is a better diligence position than most acquirers ever get.

The size of the cheque

Stripe announced a tender offer on 24 February at a $159 billion valuation, alongside an annual letter reporting that businesses running on Stripe generated $1.9 trillion in total volume in 2025, up 34 per cent on 2024 and equivalent to roughly 1.6 per cent of global GDP. Against that mark, a price of more than $7 billion is at least about 4 per cent of the company’s own valuation, on our arithmetic and using a floor rather than a settled figure. That letter makes no mention of OpenRouter, which places any deal after it.

What would settle it

An 8-K is not coming: Stripe is private and so is OpenRouter. The confirmations that would count are ordinary ones. A post on either newsroom. A note to OpenRouter’s developers about who owns their routing layer. A named executive saying it on the record rather than a spokesperson declining to discuss rumours.

Until one of those arrives, the accurate version is the narrow one. Bloomberg says the agreement is done, the companies will not say so, and the price in the reporting has already fallen once.
