California accelerates AI oversight and seeks shutdown-safeguard recommendations
On September 18, 2026, Governor Gavin Newsom issued Executive Order N-9-26, accelerating California’s independent AI oversight programs. It sets May 1, 2027 for the agency’s SB 813 verification-organization framework and December 1, 2027 for specified AI auditor-registry implementation.[1]
By November 16, 2026, agencies must recommend possible state-law changes involving onsite independent evaluators, verified safety documentation, emergency shutdown mechanisms and reporting of loss-of-control incidents. These are proposals for assessment, not newly imposed company obligations. CalMatters reports that some revisit safeguards in the earlier vetoed SB 1047.[1][2]
Australia opens consultation on AI infrastructure and training standards
On September 18, 2026, Australia opened public consultation on proposed national standards for large data centres and frontier-AI training. The consultation opened at 6 am AEST and closes at 5 pm AEDT on October 9. Its submission form is available, and ABC reports that consultation has opened.[3][4][5]
The government seeks views on energy, water, land and community impacts, transparency and safeguards for AI training. Copyright policy is expressly outside this consultation and remains a separate workstream. The government plans legislation; the proposed standards are not yet enacted obligations.[3]
The form permits anonymous submissions and says approved AI tools may assist with analysing responses, subject to privacy and security controls and departmental review.[4] See September 17 announcement coverage.
Public comment opens on Pinnacle settlement in RealPage antitrust case
On September 18, 2026, DOJ published a Federal Register notice inviting public comments within 60 days on Pinnacle’s proposed settlement in United States v. RealPage, Inc. The proposal addresses alleged sharing of competitively sensitive rental information and algorithmic pricing coordination.[6]
DOJ filed the proposed judgment on September 4. Publication begins a public-review step; it does not mean the court has approved the settlement. DOJ’s separate procedural filing explains that court entry follows the Tunney Act process and a public-interest determination.[7]
NIST seeks input on medical standards for AI
On September 18, 2026, NIST published a request for input on medical measurement and standards, including how standards processes should adapt to AI in healthcare. NIST and NIH’s NIBIB will use responses to inform a future roadmap; the notice does not establish binding AI requirements.[8]
Written comments are due November 30 at 11:59 pm Eastern Time. NIST’s separate symposium page confirms the roadmap effort, the comment deadline and a September 24 stakeholder meeting.[9]
Virginia creates AI task force and directs data-centre accountability measures
On September 18, 2026, Governor Abigail Spanberger signed Executive Order 22, creating a rapid-response AI task force and an AI Policy Planning Unit. Their work includes existing enforcement options, cybersecurity, workforce displacement and data privacy.[10]
The order also directs data-centre transparency and environmental measures, including restrictions on new nondisclosure agreements by state executive-branch bodies and employees under the Governor’s supervision. It takes effect upon signing. Cardinal News reports mixed reactions as the state develops implementation details and related legislative proposals.[10][11]
Consumers challenge alleged AI-development coordination under antitrust law
Four consumers filed Buist v. Anthropic PBC in the Northern District of California on September 18, 2026, alleging that Anthropic, OpenAI OpCo LLC, SpaceXAI LLC and Google LLC coordinated to slow improvement of competing AI subscriptions in violation of the Sherman Act.[12]
The proposed class action seeks treble damages and an injunction. It brings the debate over coordinated AI development into antitrust litigation. Politico reports that the defendants did not immediately respond to requests for comment.[12][13]
Universal and Sony file second Suno copyright lawsuit
Universal and Sony label plaintiffs filed a second lawsuit against Suno on September 18, 2026, alleging unauthorized use of 60,202 sound recordings for AI training and circumvention of YouTube access controls. The Massachusetts complaint seeks damages and injunctive relief.[14]
Music Business Worldwide reports that the action follows a decision limiting expansion of the earlier Suno case and also challenges the provenance of Suno’s v6 models.[15]
