On May 22, 2023, an AI-generated image of an explosion at the U.S. Pentagon went around Twitter.

The image was convincing enough that many people believed it to be real,  

and the stock market reacted accordingly. The S&P 500 index shed $500 billion 

in value in the hours following the image's release. 

The fake explosion image was created by a user on the social media platform Discord. 

The user, who has not been identified, used an AI program to generate the image. 

The image was then shared on Twitter, where it quickly went viral. 

The image was so convincing that many people believed it to be real.  

Some people even took to Twitter to express their condolences to the victims of the explosion. 

However, it soon became clear that the image was fake. 

The Pentagon released a statement saying that there had been no explosion at the building.
