The next debate was already held on May 28, 2026, at 6 p.m. between Rodney Glassman and Warren Petersen, so there does not appear to be a currently scheduled next debate in the sources I found.

What’s known

  • The May 28 debate was confirmed by multiple Arizona outlets.
  • Reporting around June 5 also refers to that event as a televised debate that had already happened.
  • I did not find a later, officially announced rematch or follow-up debate in the results available to me.

Timing

  • Arizona’s primary election is July 21, 2026, which may be why coverage around Glassman and Petersen is still active.
  • If you meant “when is the next debate after the May 28 one,” I couldn’t verify another date from the available public coverage.

Quick note

If you want the most useful follow-up, the answer is: no later debate date is currently confirmed in the public coverage I found.
