Trump Administration Requests OpenAI Stagger GPT-5.6 Release for Security Vetting

Jun 25, 2026

At the request of the Trump administration, OpenAI has agreed to stagger the release of its new GPT-5.6 model suite, launching a limited preview on June 26, 2026, where the government will approve customer access on a case-by-case basis. The intervention follows a June 2, 2026 executive order establishing a voluntary 30-day vetting window for advanced AI models. Amid this regulatory pressure and market volatility, OpenAI is also leaning toward delaying its highly anticipated IPO to 2027.

GPT-5.6 staggered release

▪The Trump administration requested that OpenAI delay and stagger the release of its next AI model, GPT-5.6, citing cybersecurity risks.
▪OpenAI CEO Sam Altman told staff that GPT-5.6 would launch in a limited preview to a selective group of partners, with the government approving access customer by customer.
▪OpenAI officially unveiled the limited preview of the GPT-5.6 model suite on June 26, 2026, consisting of three models named Sol, Terra, and Luna.

Government security vetting process

▪The Office of the National Cyber Director and the Office of Science and Technology Policy were the two federal agencies involved in requesting OpenAI's staggered release.
▪OpenAI dedicated approximately 700,000 A100e GPU hours to automated red-teaming and worked with third-party testers to evaluate GPT-5.6 safety.
▪Donald Trump's Commerce Secretary, Howard Lutnick, intervened against even a limited release of GPT-5.6, calling Sam Altman to demand approvals from other agencies.

OpenAI IPO delay to 2027

▪OpenAI completed its corporate restructuring in October 2025, converting its for-profit arm into a public benefit corporation named OpenAI Group PBC.
▪OpenAI is leaning toward delaying its planned initial public offering from late 2026 to 2027, a decision supported by Chief Financial Officer Sarah Friar.

Federal frontier model oversight

▪The White House forced Anthropic to pull its Claude Mythos and Fable 5 models offline under national security and emergency export control directives.
▪President Donald Trump signed an executive order on June 2, 2026, establishing a voluntary framework for government cybersecurity teams to assess advanced AI models for 30 days before public release.

Market volatility concerns

▪News of OpenAI's potential IPO delay sank the stocks of SoftBank Group Corp. and memory chipmaker Kioxia.
▪OpenAI's IPO timing considerations are influenced by recent market turbulence, including SpaceX's June 11, 2026 IPO which surrendered most of its debut gains.
