Story summary

A study released on October 21, 2026, by NewsGuard found that X Community Notes, a user-generated verification system introduced by Elon Musk’s X in late 2022, failed to flag 93.1% of false claims related to the US midterm elections. The study identified dozens of posts on X spreading misinformation, including baseless allegations of election fraud, yet only 13 were tagged with Community Notes. These uncorrected posts garnered millions of interactions before the November 3 midterm elections. Researchers have long questioned the effectiveness of such crowdsourced fact-checking programs in combating misinformation.
