The Oxford Open is an open tournament written and hosted by Oxford. Its first four iterations were all won by teams from the University of Chicago, which flew out every year to compete. Two of these (2014 and 2015) featured Chicago v. Chicago finals. The earlier of these results led to a heated exchange on Facebook among various members of the British quizzing community, in part because the second-place team was led by then-freshman Morgan Venkus. Since 2017, Oxford Open has been won by British teams.
