Stripe bets that an AI world still needs middlemen

AI is likely to upend the economy, but Stripe’s purchase of OpenRouter for about $8bn is a bet that at least some things will remain familiar — namely, the need for middlemen.

On the face of it, it looks like an odd move. Stripe’s main business is facilitating online payments; OpenRouter helps businesses choose which AI models to use for different tasks. The business, founded by Alex Atallah of OpenSea fame, may not be as obvious a target as PayPal, the online payments group that Stripe is also trying to buy. But if one believes — as Stripe’s founders do — that AI is an important part of the future of commerce, the move makes strategic sense.

After all Stripe, despite being known primarily for taking payments, already provides various other services for businesses. Most entrepreneurs are keen to focus on their products and happy to pay a little to someone who can reliably handle mundane but important areas of financial infrastructure such as fraud detection, tax and outbound payments. Stripe says fast-growing start-ups in particular want a provider that can handle “their entire financial stack”. So if AI subscriptions become a key business expense for Stripe’s clients, the group has a good chance of getting paid to manage them alongside the rest of their payments.

The key assumption here is that the future, in Atallah’s words, is “multi-model”: if OpenAI, for instance, came up with a product that surpassed competitors in every sphere, businesses wouldn’t need as much help shopping around. But so far at least, the top spots in the leaderboard are tightly contested and major companies like Amazon and Uber are either putting caps on staff AI usage or encouraging them to switch to cheaper models to keep spending under control, so at least some level of multi-model use seems a safe enough bet.

One might still question the price tag, given that OpenRouter raised money at a $1.3bn valuation barely three months ago. The Information reported that OpenRouter recently hit an annualised revenue rate of around $140mn, implying a deal valuation of almost 60 times annual revenue. That’s steep, but OpenRouter is growing rapidly. And compared with public groups like Meta, privately-held Stripe has less to fear from spooking investors with risky “side-quests”.

A bigger risk than overpaying for a single company would be if, in its rush to expand, Stripe lost some of what made it so popular in the first place. The payments world is littered with groups that grew massive through multiple acquisitions but struggled to knit them all together and lost ground to more agile start-ups — foremost among them, Stripe itself. OpenRouter is Stripe’s fifth acquisition since the start of 2025, according to PitchBook data; so far they have all been fairly small, but PayPal in particular would be a different order of magnitude. Stripe will have to ensure that, in its quest to prepare for the future, it doesn’t end up recreating the past.
