The schedule for talks and list of all (not just invited) presenters* at #ICM2026 is now on the web site.  https://www.icm2026.org/ The web interface is a little clunky, maybe there will be a conference phone app for participants.

*I am still planning to attend and give a short talk - after seriously considering the well-known petition and call for boycott, an ethical quandary which I would rather not hash out on social media.

I have registered for ICM 2026 in Philadelphia at the end of July! If you'll be there and would like to meet up at some point for hallway track or food or drinks, please get in touch!

The 2026 ICM (International Congress of Mathematicians) will be held in July in Philadelphia, where I live. I'd like to attend.

The ICM allows a regular participant to co-register an “accompanying person”. I'd like to be an “accompanying person”.

If you plan to attend and would be willing to register me as an accompanying person, please DM me. I would of course pay the registration fee. I will also, if you like, treat you to dinner.

I am a middle-aged computer programmer, formerly a math major, who has retained a serious interest in mathematics.

Please circulate this notice to potentially interested parties.

Statement from the @AustMS about #ICM2026

"To the International Mathematics Union,

The Australian Mathematical Society calls upon the IMU to reconsider Philadelphia in the USA as host venue for the 2026 ICM due to potential difficulties for international delegates to obtain visas to attend, the potential risks to international delegates arising from the activities of the USA’s Immigration and Customs Enforcement officers, and the potential dangers arising from the involvement of the host nation in current warfare.

Yours sincerely,
Aidan Sims
President of the Australian Mathematical Society
(May 1, 2026)"

Prof. Susanna Zimmermann has been invited to speak at the International Congress of Mathematicians — the most influential conference in mathematics.
She is the first woman from the University of Basel to receive this distinction. Her work advances the study of algebraic groups acting via birational transformations.
