# September 11 conspiracy theory evolution > Live situation record from CLSTR: https://clstr.news/situations/september-11-conspiracy-theory-evolution > Updated: 2026-09-10T21:36:23.000Z. Sources: 7. Developments: 2. Twenty-five years after the September 11 attacks, various conspiracy theories continue to circulate. Some groups, such as the ‘Truth Movement’, claim the United States government withheld information to facilitate an authoritarian regime, often arguing that explosives were used to collapse the Twin Towers. Official investigations by the National Institute of Standards and Technology (NIST) have countered these claims, stating that heat from jet fuel weakened the steel enough to trigger collapses without the need for explosives. As the 25th anniversary approaches, there has been a documented rise in antisemitic narratives related to the attacks. Organizations like the Anti-Defamation League (ADL) have noted that the number of tracked antisemitic 9/11 conspiracy theories increased from 35 in 2022 to 68 in 2025. These evolving theories often use coded language or caricatures on social media to evade moderation and have begun utilizing artificial intelligence to manufacture synthetic ‘proof’ to support claims blaming Jewish people or Israel. ## Timeline ### 2026-09-10: Antisemitic 9/11 conspiracy theories resurface ahead of 25th anniversary Antisemitic conspiracy theories regarding the 9/11 attacks are resurfacing and evolving through social media and AI-generated content as the 25th anniversary of the event approaches. 2 sources. https://clstr.news/cluster/antisemitic-911-conspiracy-theories-resurface-ahead-of-25th-anniversary ### 2026-09-10: 9/11 conspiracy theories persist 25 years after attacks Twenty-five years after 9/11, conspiracy theories persist despite NIST findings that structural weakening, not melting steel or explosives, caused the Twin Towers' collapse. 5 sources. https://clstr.news/cluster/911-conspiracy-theories-persist-25-years-after-attacks --- Cite as: September 11 conspiracy theory evolution.
