Elon Musk's Grok chatbot disseminated false information regarding the deadlines for several US states’ 2024 presidential ballots, raising questions about its sources and tendency to "hallucinate" false "facts".

Citing an X post by a conservative pundit as its source for the information, Grok incorrectly stated that presidential ballot deadlines had passed in nine states, including Alabama, Indiana, Michigan, Minnesota, New Mexico, Ohio, Pennsylvania, Texas, and Washington. 

The chatbot also wrongly claimed that presumptive Democratic nominee and Vice President Kamala Harris had missed the ballot deadline, and suggested that President Joe Biden's name could not be replaced on these states' ballots due to passed deadline - which is false.

In reality, US states do not start printing ballots until after both party conventions, and the Democratic Party will formally nominate its nominee through a virtual roll call vote.

Minnesota Secretary of State Steve Simon reportedly traced the misinformation to Grok and tried to inform X about the issue, but received no response.
