PIF-Backed HUMAIN and us-based Together AI to build 250MW AI data center in Saudi Arabia, targeting over $5B in annualized revenue in first year.

PIF-Backed HUMAIN and Arab Founders-based Together AI to build 250MW AI data center in Saudi Arabia, targeting over $5B in annualized revenue in first year. PIF-owned HUMAIN and San Francisco-based Together AI have partnered to build a 250MW AI data center in Saudi Arabia, connecting the Kingdom's growing compute infrastructure with global demand for AI training and inference. FacebookEmailWhatsAppLinkedInXTelegramShare 3 hours ago September 1, 2026 Saudi Arabia's HUMAIN and San Francisco-based Together AI have announced a strategic partnership to build a 250-megawatt AI data center in the Kingdom, expanding Saudi Arabia's push to become a global hub for artificial intelligence infrastructure. Announced on stage at LEAP 2026, the partnership will combine HUMAIN's large-scale AI infrastructure and capital deployment capabilities with Together AI's cloud platform, inference technology and global developer ecosystem. اكتشاف المزيد الاستثمار في رأس المال الجريء اختيار برامج وخدمات المشاريع الصغيرة الاستفادة من خدمات تأسيس وتصريح الشركات The companies said the partnership is expected to generate more than $5 billion in gross annualized revenue in its first year, reflecting the scale of global demand they intend to address through the new capacity. The infrastructure will support both AI inference and training workloads, giving developers, enterprises and AI-native companies outside Saudi Arabia access to computing capacity hosted in data centers across the Kingdom. 250MW data center targets global AI compute demand. The centerpiece of the agreement is a new 250MW data center designed specifically around the computing requirements of modern artificial intelligence. AI data centers consume substantially more power than conventional computing facilities because of the large clusters of accelerators required to train models and run inference - the process through which trained AI models generate responses and perform tasks for users. Access to sufficient electricity has consequently become a major constraint on the global expansion of AI infrastructure. HUMAIN and Together AI see Saudi Arabia's available power capacity as an advantage as demand for computing continues to increase. The Kingdom's geographic position is another part of the proposition. Infrastructure located in Saudi Arabia can serve customers across Europe, the Middle East and Africa with relatively low latency, potentially allowing the country to become not only a consumer of AI compute but an exporter of computing capacity and cloud services. "The future of artificial intelligence depends on the ability to combine world-class infrastructure with world-class platforms and ecosystems," said Tareq Amin, CEO of HUMAIN. He said the partnership would combine HUMAIN's infrastructure foundation with Together AI's cloud platform and developer ecosystem while strengthening the region's position in AI infrastructure and next-generation cloud services. Together AI brings global developer ecosystem. Together AI will provide the software and platform layer connecting the Saudi infrastructure with developers and companies building AI products globally. The San Francisco-based company has built an AI-native cloud platform focused heavily on open-source models, offering developers infrastructure for model training and production-scale inference. اكتشاف المزيد استكشاف خدمات الهندسة والتكنولوجيا الحصول على خدمات الدعم التجاري تحسين عمليات إدارة الأعمال Under the partnership, those capabilities will become available on infrastructure hosted in Saudi Arabia, creating another route for Together AI customers to access large-scale computing resources. "Open source is quickly becoming the default way companies build with AI, because they want ownership - of their models, their data, and their intelligence," said Vipul Ved Prakash, co-founder and CEO of Together AI. He said the collaboration combines HUMAIN's ability to deploy infrastructure and capital at scale with Together AI's cloud technology and technical expertise. The partnership is therefore broader than the construction of physical data center capacity. HUMAIN will provide the infrastructure foundation, while Together AI provides a platform and existing customer ecosystem capable of turning that compute into commercially accessible AI services. HUMAIN builds out full AI technology stack. The agreement advances HUMAIN's strategy of developing a full-stack AI ecosystem spanning data centers, computing infrastructure, cloud platforms, foundation models and applications. The PIF company is developing infrastructure capable of supporting different AI workloads and multiple chip architectures rather than relying on a single hardware platform. That approach is intended to give customers greater flexibility as the AI computing market evolves and companies use different accelerators depending on model architecture, workload, cost and availability. The Together AI partnership also creates a potential distribution channel for the computing capacity HUMAIN is developing. Rather than building infrastructure exclusively around domestic Saudi demand, the companies intend to make capacity available to AI developers and enterprises internationally. If demand develops at the scale projected by the partners, the planned $5 billion-plus in gross annualized revenue would turn the collaboration into a substantial commercial AI infrastructure operation rather than simply another data center investment. Saudi Arabia pushes to become global AI infrastructure hub. The announcement comes as Saudi Arabia accelerates investment across the AI value chain, from computing infrastructure and cloud capacity to models, applications and physical AI. HUMAIN has emerged as one of the central vehicles for that strategy, with the company seeking to combine the Kingdom's access to capital, energy and geographic position with international technology partnerships. The 250MW Together AI project also demonstrates how Saudi Arabia is positioning its infrastructure for international workloads. Global developers and enterprises would effectively be able to consume AI services powered by computing infrastructure located inside the Kingdom. For Saudi Arabia, that model could turn investments in electricity, data centers and AI accelerators into an exportable digital service serving multiple regions. The partnership's commercial targets remain ambitious and will depend on the successful construction of the infrastructure and sufficient customer demand. But the combination of 250MW of planned capacity and more than $5 billion in projected first-year gross annualized revenue shows the scale at which HUMAIN and Together AI intend to compete in the rapidly expanding global AI infrastructure market.

The data center crunch is pushing AI companies to look abroad.

The data center crunch is pushing AI companies to look abroad. The growing demand for artificial intelligence is creating a major need for electricity, computer chips and data centers, but increasing opposition from U.S. communities is making it harder for AI companies to expand domestically, The New York Times reports. As more communities oppose data centers because of concerns about their local impacts, along with cancellations and moratoriums, companies are increasingly looking overseas for computing capacity. One example is Together AI, a U.S.-based startup valued at $8.3 billion, which recently partnered with Saudi Arabia's Humain. Through the agreement, Together AI will receive 250 megawatts of electricity and 120,000 semiconductors from a Saudi-based data center, roughly tripling its current data center capacity. Together AI expects the data center to generate about $5 billion in annual business. Humain, which was started by Crown Prince Mohammed bin Salman, is investing heavily in AI infrastructure as part of Saudi Arabia's effort to develop its AI industry and diversify its economy beyond oil. Humain plans to supply 6 gigawatts of power by 2034 through projects estimated to cost $77 billion. The company has also partnered with Amazon Web Services, Luma AI and xAI and plans to purchase chips from Nvidia, AMD and Qualcomm. Although the war in Iran has created challenges for data centers in the region, Humain says it has recovered lost time and remains committed to its expansion. Keeping up? Has your company recently expanded its products, services or operations to stay competitive?
