Blatter's spokesman, Thomas Renggli, tells The Associated Press the suspended FIFA president has hired space at world soccer's former headquarters at Sonnenberg in Zurich for the 11 a.m. (1000 GMT) event.
The FIFA ethics committee is expected to give rulings in the cases of Blatter and Michel Platini earlier Monday.
Blatter and Platini risk bans of at least several years for a rules-breaking conflict of interest.
The case centers on Platini's $2 million payment from FIFA approved by Blatter in 2011 as uncontracted salary for working as a presidential adviser from 1999-2002.
Both deny wrongdoing.
Blatter attended his ethics hearing at FIFA on Thursday. Platini boycotted his hearing on Friday.
