Marc Andreessen and Ben Horowitz will host their Clubhouse show "One On One with A & Z" on Monday, August 16, 2021 at 7:00 PM Pacific.

The claim is that Andreessen and Horowitz would host their Clubhouse show 'One On One with A & Z' on Monday, August 16, 2021 at 7:00 PM Pacific. TRUE: the episode, hosted by both of them, took place on Clubhouse at or about that date and time. MOSTLY TRUE: it took place on August 16 with both hosts, but the start time shifted somewhat, or one minor detail differed. MOSTLY FALSE: it was postponed to a later date, or took place without one of the two named hosts. FALSE: a cancellation notice, a statement that it did not happen, or the absence of an episode in a dated episode list for that period shows it was not held.

The podcast feed lists "One on One with A and Z #10" as published on August 25, 2021, and describes it as an excerpt from the Clubhouse show hosted by Marc Andreessen and Ben Horowitz (E1, E2, E5). None of the evidence says which live session the excerpt came from, so it does not show that a show took place on August 16 at 7:00 PM Pacific. The feed is a set of occasional excerpts, not a full dated list of live sessions (E6, E7), so it cannot show that the show was or was not held. Neither outcome is settled by the evidence.
