Elon Musk’s AI venture xAI has been named as the first customer for a major data-centre facility in Saudi Arabia under the government-backed HUMAIN initiative, equipped with hundreds of thousands of NVIDIA graphics-processing units.

The announcement was made during a U.S.–Saudi investment event in Washington where Musk and NVIDIA chief Jensen Huang appeared together.

The facility, developed by HUMAIN — a subsidiary of Saudi Arabia’s Public Investment Fund — is designed with a planned capacity of up to five hundred megawatts and will be built using Nvidia’s most advanced GPUs.

HUMAIN confirmed the involvement of roughly six hundred thousand Nvidia chips in the build-out.

The first tranche of eighteen thousand Nvidia GB300 “Blackwell” chips was publicly disclosed earlier in the year under a broader partnership to deploy sovereign AI infrastructure in Saudi Arabia.

According to an export control filing, the U.S. Commerce Department has authorised the supply of up to thirty-five thousand of Nvidia’s Blackwell chips to Saudi and Emirati AI firms — a move timed to coincide with the Saudi Crown Prince’s Washington visit and aligned with strategic U.S. interests in advanced technology partnerships.

The authorisation underscores the diplomatic dimension of the Saudi build-out, as the Kingdom seeks to position itself as a regional AI hub while deepening ties with American tech and investment interests.

In the deal, xAI will utilise the Saudi data centre to support its AI-model training and deployment, plugging into the large-scale infrastructure HUMAIN is deploying.

The arrangement aligns with xAI’s broader expansion plans, which have included leasing data-centre capacity in energy-rich, geopolitically aligned jurisdictions such as Saudi Arabia.

The timing of the announcement reflects the growing intersection of national-scale compute infrastructure and geopolitical strategy.

NVIDIA has referred to such facilities as “sovereign AI” projects, positioning them as foundational infrastructure for countries seeking to control their own AI ecosystems rather than depend solely on global cloud providers.

Beyond Nvidia, other chip-provider partnerships are reportedly in place: Advanced Micro Devices (AMD) has announced a multi-billion-dollar agreement to supply hardware for Saudi data-centre expansion, while Qualcomm has also signed memoranda of understanding to provide next-generation data-centre chips to HUMAIN.

The strategic significance for the Trump administration includes reinforcing U.S. tech leadership and fostering deep Saudi investment in American platforms.

While precise financial terms for xAI’s-Saudi engagement were not disclosed, the scale of the hosting environment and chip commitment signal a major leap for both parties.

For Saudi Arabia, the deal enhances its regional AI ambitions and supports the long-term objective of becoming a global AI computing hub.

For xAI and Nvidia, it represents a high-profile client deployment anchored in geopolitics and emerging infrastructure architecture.

The success of this programme will hinge on timely execution of the data-centre build-out, energy and cooling infrastructure, chip-supply chain resilience, and alignment with regulatory and sovereign-data requirements.

For now, the announcement marks a significant step in the fusion of national strategy and commercial AI deployment.
