Financial arrangements between the two parties must be made public. The team had requested the contents of the deal be sealed. A Guggenheim spokesman said there were no plans to appeal the ruling.
The team was sold in 2012 for $2 billion. McCourt and Guggenheim will share profits from a joint venture as part of the deal.
The ruling is part of a divorce case in which McCourt's ex-wife wants a $131 million settlement thrown out because she believes she was misled about the team's value.
McCourt's attorney declined comment.
