Nvidia: US GAIN AI Act Sparks Debate on Data Centre Chips
The US semiconductor industry is bracing for tighter export restrictions under the Guaranteeing Access and Innovation for National Artificial Intelligence Act of 2025 (GAIN AI Act).
The legislation would require domestic chipmakers to prioritise US buyers before selling advanced processors overseas, a move that could significantly affect global data centre operators reliant on high-performance GPUs.
The measure forms part of the National Defense Authorisation Act and arrives as Washington seeks to balance national security with the commercial realities of supplying an international AI market.
What is the GAIN AI Act?
The GAIN AI Act would establish a clear framework for AI chip exports. US chipmakers would be legally required to fulfil domestic demand first, before exporting processors to international customers.
- US chipmakers must prioritise American buyers before exporting
- Advanced chips over power thresholds need export licences
- Keep top AI hardware available for US organisations
- Aim to boost national security and US AI leadership
The act singles out processors with total performance power of 4,800 or above, creating a binary export control system based on capability rather than geography. This marks a shift from the Biden administration’s AI Diffusion Rule, which relied on a complex country-tier structure.
Supporters argue the new approach will ensure that US businesses, universities and data centres have the computing power required to accelerate AI development without facing delays from global competition.
Nvidia pushes back
Nvidia has strongly opposed the proposed legislation, insisting that the restrictions are unnecessary.
“We never deprive American customers in order to serve the rest of the world,” a company spokesperson, according to Reuters.
“In trying to solve a problem that does not exist, the proposed bill would restrict competition worldwide in any industry that uses mainstream computing chips.”
The GPU maker has drawn comparisons between the GAIN AI Act and the rescinded AI Diffusion Rule.
“The AI Diffusion Rule was a self-defeating policy, based on doomer science fiction and should not be revived,” the company said.
“Our sales to customers worldwide do not deprive US customers of anything – and in fact expand the market for many US businesses and industries. The pundits feeding fake news to Congress about chip supply are attempting to overturn President Trump’s AI Action Plan and surrender America’s chance to lead in AI and computing worldwide.”
Nvidia’s filings show that US customers already represent nearly half of its business, accounting for 49.9% of revenue in fiscal 2024. China contributed 28% and Singapore 18%.
Implications for data centres
For data centres, the legislation would directly influence access to GPUs used in training large language models and other compute-intensive AI systems.
The thresholds outlined in the GAIN AI Act could impact not only the latest AI accelerators but also older models such as Nvidia’s HGX H20 or L2 PCIe, which were designed to comply with previous restrictions while serving international markets.
With GPUs increasingly treated as critical digital infrastructure, data centre operators fear delays in global supply chains that could stall new deployments or expansions. The challenge is compounded by demand consistently outpacing supply, forcing operators across regions to compete for limited production volumes.
Industry division
Not all voices in the sector are aligned with Nvidia’s stance. Brad Carson, President of Americans for Responsible Innovation, supports the GAIN AI Act, highlighting the importance of prioritisation.
“Globally, these chips are currently supply-constrained, which means that every advanced chip sold abroad is a chip the US can’t use to accelerate American R&D and economic growth,” said Brad.
“As we compete to lead on this dual-use technology, including the GAIN AI Act in the NDAA would be a major win for US economic competitiveness and national security.”
The debate underscores a wider issue: how to balance national priorities with the demands of a globalised AI ecosystem.
For cloud providers and hyperscalers operating international data centres, the outcome of the GAIN AI Act could dictate whether they continue to scale efficiently or face delays in acquiring the infrastructure that powers modern AI.
