JPMorgan Chase has agreed to a massive sponsorship deal with Madison Square Garden worth at least $30 million a year, which stands as the most lucrative annual building/team sponsorship agreement to date.

Multiple sources confirmed the top-level deal valued at $300 million over 10 years or more in securing rights to almost every asset in the Garden, which is undergoing an $800 million phased renovation with final completion expected by 2013.
