The Black Market in Fisch usually only appears on real‑life weekends and has a 75% chance to spawn every 15 minutes while it is active, staying up for about 10 minutes each time.

Quick Scoop

  • The Black Market is a limited-time weekend shop, not an always-on feature.
  • During Friday night through Sunday, the game repeatedly rolls a spawn chance roughly every 15 minutes, with about a 75% chance each roll that a Black Market instance appears.
  • When it does spawn, it remains available for around 10 minutes before disappearing again, so players often server-hop or camp during those windows.

Many current guides and forum-style articles emphasize treating weekends as “hunt time,” checking in regularly every 15 minutes or watching for server- wide announcements and Discord alerts to avoid missing a spawn.

TL;DR: On weekends, expect a possible Black Market roughly every 15 minutes, but each one only sticks around for about 10 minutes, and spawns are not guaranteed.
