White House AI and Crypto Czar David Sacks on Sunday, 19 July 2026, issued a pointed rebuke of a strategy he described as weaponising regulatory uncertainty to suppress Chinese open-source AI models — warning that such an approach corrodes the rule of law and ultimately harms everyone. Sacks called on the broader Silicon Valley community to openly defend open competition against what he characterised as a push by dominant closed-model AI laboratories to use government machinery to eliminate their open-source rivals.

Context

Sacks was responding to an argument, attributed to commentator Dean Ball, that there is no need for an outright ban on Chinese open-source AI models. Instead, the argument goes, federal agencies could issue informal 'soft-law' warnings — guidance documents, advisories, and similar instruments — that generate enough fear, uncertainty, and doubt (FUD) among regulated enterprises to make them voluntarily avoid those models. Ball has since clarified he was predicting this outcome rather than endorsing it.

Sacks rejected both the strategy and its framing. Quoting Ball's phrase 'It needn't be that well justified,' he wrote: 'Regulatory decisions should always be well justified and grounded in facts, logic, and evidence, not the deliberate exploitation of fear and uncertainty.' He described implementing policy through 'manufactured doubt' as a threat to the rule of law that 'invites future abuse against anyone.'

Policy Backdrop

The debate sits at the intersection of two long-running tensions in US AI policy: promoting domestic innovation through open-source development versus imposing security-driven restrictions on foreign technology. The Biden administration's October 2023 executive order on Safe, Secure, and Trustworthy Artificial Intelligence directed federal agencies to develop AI standards and risk assessments, while the CHIPS and Science Act of 2022 authorised export controls aimed at maintaining US leadership in semiconductors and AI.

Successive administrations have preferred a layered toolkit — formal rules, export controls, and agency guidance — rather than outright bans on specific technologies, a pattern applied across semiconductor, software, and data sectors. The question now before the Trump administration, in which Sacks holds his AI and Crypto Czar role, is whether informal soft-law instruments can or should be used to achieve outcomes that explicit regulation has not yet sanctioned.

Stakeholders and Impact

Sacks identified the central fault line clearly: the leading closed AI laboratories, which he described as already constituting 'a duopoly in terms of AI model revenue,' have an interest in using government levers to suppress open-source competition — including models originating from China. Open-source developers, AI startups, and the enterprises that deploy their models stand on the other side of this divide.

For regulated industries — finance, healthcare, critical infrastructure — even informal agency guidance can carry the practical weight of a mandate. If agencies signal that Chinese open-source models carry unspecified risks without providing concrete evidence, compliance departments in those sectors are likely to steer clear regardless of any formal legal requirement. That outcome, Sacks argued, is precisely what the soft-law strategy is designed to produce.

What's Next

Sacks ended his post with a direct appeal: 'The leading closed labs... have laid their cards on the table. It is time for the rest of Silicon Valley — the vast majority that still values open competition — to do the same.' The statement amounts to a call for open-source advocates and smaller AI players to organise and make their position visible in the policy debate.

Congressional consideration of AI regulatory frameworks and any new executive orders or agency guidance from the Trump administration on model development and deployment will be the immediate arena to watch. Whether Sacks's intervention shifts the internal administration calculus — given his own role as the president's top AI and crypto adviser — makes this a moment of unusual public transparency about divisions within Washington DC's AI policy establishment.
