The visit takes place just weeks after Mr. Musk apologized for supporting an antisemitic conspiracy theory and following harsh criticism of how X, the former Twitter, handles antisemitic posts.
Reputable Jewish figures urged Mr. Musk to visit one of the Holocaust’s most significant locations.
Later, at a conference organized by the European Jewish Association (EJA), he will speak about online antisemitism.
During World War Two, Nazi Germany slaughtered at least 1.1 million people at the Auschwitz death camp in occupied Poland. There were about a million Jews. More than 200,000 of them were children and young people, according to the museum.
During a private visit to the location, Mr. Musk placed a wreath and took part in a memorial service that included lighting a candle.
Pictures of him there showed him standing next to Holocaust survivor Gidon Lev, his son on his shoulders.
Advertisers depart
Apple, Disney, and IBM halted advertisements on X due to the backlash following Mr. Musk’s enthusiastic agreement with an antisemitic post.
The businessman responded by accusing the advertisers of trying to “blackmail” him with money and by using foul language to show his contempt for what they were doing.
