Aramco Leads Together AI's $800 Million Raise

Together AI closed an $800 million Series C on July 1, lifting the San Francisco company's valuation to $8.3 billion, according to TechCrunch. The round was led by Aramco Ventures, the investment arm of Saudi Arabia's state oil company, through its Prosperity7 fund. Nvidia joined the round, as did Vista Equity Partners, General Catalyst, Salesforce Ventures and Schneider Electric's SE Ventures, among others.

The raise brings Together AI's total funding to $1.3 billion. The company said its annual bookings passed $1.15 billion in the most recent quarter, the figure it points to when it argues the business is close to an eventual public listing. Abhishek Shukla, the Prosperity7 managing director who led the deal, told reporters the company is headed towards the public markets, and framed the sector in characteristically large terms, calling AI infrastructure the biggest infrastructure project in human history.

A bet on open weights

What makes this more than another big cheque is the thesis behind it. Together AI runs a cloud built to serve open-weight models, the kind you can download and host rather than rent from a single provider. Its pitch to enterprises is straightforward: the gap between open models and the best closed systems has narrowed to the point where paying frontier prices no longer makes sense for most work. Several outlets covering the round, including TechFundingNews, framed it as evidence that companies are moving budget away from closed models and toward open ones they can run more cheaply.

That view has a lot of supporting evidence lately. Chinese labs have been shipping capable open models at a pace that keeps resetting the price floor, from Meituan's 1.6-trillion-parameter LongCat 2.0 to Z.ai's GLM-5.2. Every strong open release makes Together AI's argument easier to make. If the model is free to download, the money is in running it well, and that is the business Together AI is in.

The Aramco angle

The identity of the lead investor is worth sitting with. A Saudi state oil fund backing an American AI infrastructure company is a reminder of how much petro-capital is now flowing into compute. Gulf sovereign money has been chasing AI exposure for two years, and a neocloud with real revenue is a cleaner bet than a frontier lab burning billions on training runs. For Together AI, the trade-off is the usual one that comes with sovereign backing: patient capital and deep pockets, paired with a backer whose interests reach well beyond the balance sheet.

The raise lands the same week that SpaceX signed a multibillion-dollar compute deal with an open-source lab, another sign that the money moving into AI right now is flowing toward the picks-and-shovels layer as much as the models themselves. Whether open weights really do hollow out demand for closed frontier systems is still an open question. Together AI just raised $800 million on the wager that they will.
