Howlin' Wolf has brought a lawsuit against StubHub. The music venue in New Orleans is taking action. It involves speculative ticket sales. Tickets were sold on StubHub before the venue confirmed them. StubHub functions as an online ticket resale marketplace. Speculative sales take place when sellers advertise tickets they don't own yet. Howlin' Wolf claims this happened without approval. No more details have so far been given. The lawsuit seeks to address this kind of early listing. StubHub permits resales, but this case challenges the timing of listings.
