Former President Donald Trump told Nvidia CEO Jensen Huang on speakerphone that AI existential fears are a hoax during the All-In Summit in Los Angeles on Monday, September 14, 2026, capping a weekend of escalating public debate over AI safety in Washington and Silicon Valley.
Quick Answer
On the evening of September 14, 2026, Donald Trump joined the All-In Summit in Los Angeles by phone. Nvidia CEO Jensen Huang put Trump on speakerphone in front of the audience. Trump said: I'm telling you, it's all a hoax; The robots are not going to be taking over the world; and WHOEVER WINS AI, WINS! Trump also posted on Truth Social, calling himself the Hoax Buster and comparing the AI doomsday narrative to past political hoaxes (Fox Business, September 15, 2026).

What happened at the All-In Summit on September 14
The All-In Summit ran from September 12 to 14, 2026, in Los Angeles, with Trump joining the closing day on speakerphone. The four hosts — David Sacks, Chamath Palihapitiya, Jason Calacanis, and David Friedberg — were on stage when Trump called in. Jensen Huang was on stage as well, and Huang put the call on speakerphone so the audience could hear Trump's remarks. Trump spoke for roughly seven minutes, with Huang occasionally interjecting (Fox Business, September 15, 2026).
The call comes at a sensitive moment for federal AI policy. The White House Office of Science and Technology Policy released an AI Action Plan in July 2025, and a bipartisan group of senators introduced the Catastrophic Risk Bill on September 15, 2026, the day after Trump's remarks. The bill would establish a federal body to oversee frontier AI risk and authorize the Department of Commerce to require third-party audits of AI systems above a compute threshold (TIME, September 15, 2026).
Trump's Truth Social posts on AI
Trump amplified his All-In Summit comments on Truth Social the same evening. In three posts between 11:00 pm and 11:45 pm EDT on September 14, 2026, Trump called himself the Hoax Buster, said the AI doomsday narrative is the latest in a series of political hoaxes including the Global Warming Scam and the Russia, Russia, Russia Hoax, and tied AI competitiveness to national security (BBC News, September 15, 2026).
The posts did not reference specific AI safety bills under consideration in Congress. They also did not address the Anthropic Mythos browser and OS vulnerability disclosures from April 2026, which prompted Treasury Secretary Scott Bessent to convene a meeting with bank CEOs about AI cyber risk (Bloomberg, September 15, 2026).
Reactions across the AI safety community
AI safety researchers pushed back against the hoax framing within hours. Bilal Chughtai, who resigned from Google DeepMind in July 2026 and posted his concerns publicly on September 15, 2026, called the hoax framing dangerous because it understates the magnitude of frontier AI risk. Three other safety researchers publicly backed Chughtai's view within 24 hours: Anthropic's Evan Hubinger, who estimated extinction risk above 10 percent this decade; Geoffrey Hinton, the Nobel laureate who called the figure not unreasonable; and Stuart Russell of UC Berkeley (The Independent, September 15, 2026).
Industry reaction was mixed. OpenAI's chief executive Sam Altman told reporters on September 15, 2026, that he agreed with Anthropic CEO Dario Amodei that the industry should pace frontier AI development, a position he first articulated publicly on July 28, 2025. The CEO of Nvidia was on stage during the All-In call and did not challenge the hoax framing, but did note in a separate statement that AI safety research is essential to the long-term competitiveness of US AI companies (TechCrunch, September 15, 2026).
What changes in Washington this week
The hoax comments complicate, but do not derail, federal AI safety momentum. Senate Majority Leader John Thune and Senators Ted Cruz and Amy Klobuchar introduced the Catastrophic Risk Bill on September 15, 2026, the day after Trump's call. The bill has 14 co-sponsors from both parties and is expected to move to committee markup in October 2026 (Bloomberg Law, September 15, 2026).
Trump's hoax framing matters most for the international AI policy track. The US, UK, EU, and several Asian governments are negotiating an AI safety agreement ahead of the November 2026 G20 summit. A senior State Department official told reporters on background on September 15, 2026, that Trump's hoax comments will not change the US negotiating position but will be raised by counterparts who want a stronger US commitment (Reuters, September 15, 2026).
The next test comes on September 24, 2026, when the Senate Commerce Committee holds a hearing on the Catastrophic Risk Bill. Witnesses include Anthropic, OpenAI, and Google DeepMind representatives, alongside academic and civil society voices (US Senate Commerce Committee, September 15, 2026).

How this affects AI safety governance and congressional action
The Trump hoax framing collides directly with the bipartisan catastrophic-risk bill introduced in the Senate on September 15, 2026. Senators Thune, Cruz, and Klobuchar introduced the Catastrophic Risk Act of 2026 the same morning that Trump's All-In remarks spread across financial markets. The bill directs the Department of Commerce to develop mandatory reporting thresholds for AI training runs above a defined compute threshold, with civil penalties of up to $50 million per violation and a federal revocation pathway for safety certifications. The mismatch between Trump's hoax framing and the Senate bill creates near-term uncertainty for frontier AI labs that are simultaneously negotiating voluntary commitments with the Office of Science and Technology Policy and awaiting committee markup of the Catastrophic Risk Act in October (Reuters, September 15, 2026).
Three dueling Senate bills now define the December congressional window for AI legislation. The Catastrophic Risk Act covers reporting and penalties. The Casar/Sanders superintelligence-ban bill, introduced September 14, would block any model above 10 to the 26 FLOPs of training compute from release until a new federal regulatory body certifies safety. The Obernolte/Trahan Commerce Department reporting bill, also introduced September 14 with OpenAI support, requires labs to submit quarterly model risk reports covering capabilities, mitigations, and red-team findings. None of the three is expected to clear a floor vote before the House adjourns in late September, but committee staff are reportedly merging elements of the Obernolte/Trahan framework into the National Defense Authorization Act, which moves on a separate legislative calendar (Bloomberg, September 15, 2026).
The investor reaction on September 14-15 was muted but uneven. The Nasdaq Composite fell 0.8 percent on Monday September 14, with AI-exposed names selling off disproportionately: Anthropic parent TBC fell 2.1 percent, Microsoft lost 1.4 percent, and Nvidia closed flat after recovering from a 1.6 percent intraday drop during Trump's remarks. The Goldman Sachs AI Infrastructure Basket fell 1.2 percent. Tuesday September 15 brought a partial recovery, with the Nasdaq up 0.4 percent, but analysts at Morgan Stanley and JPMorgan flagged the policy uncertainty as a near-term overhang for AI infrastructure and model-as-a-service stocks (Bloomberg, September 15, 2026).
