This summer, online bank SoFi Lending signed a 20-year deal to have its logo adorn the new $2.6 billion NFL stadium that is scheduled to open next year in Inglewood, Calif. In Las Vegas, discount airline Allegiant will do the same to the Raiders’ stadium, which is also scheduled to open next fall. Although terms were not released for that deal, Raiders owner Mark Davis hinted a week after the announcement that it was a 30-year agreement. If that is the case, both deals will buck the recent trend of shorter contracts, according to Wasserman.
