During his injury-shortened 2013 season, Jeter arranged a
partnership with Simon & Schuster to form an imprint called
Jeter Publishing. He called it "the blueprint for post career".
It will begin publishing nonfiction books for adults, children's
picture books, elementary grade fiction, and books for children
who are learning to read. Eventually, the partnership could lead
to film and television productions.
On October 1, 2014, Jeter's new website, ThePlayersTribune.com,
appeared online; it was billed as "a new media platform that
will present the unfiltered voice of professional athletes,
bringing fans closer to the games they love than ever beforeā.
It was reported by the Tampa Bay Business Journal in March 2015
that Jeter had partnered with Concessions Tampa to bid for a
space within the Tampa International Airport, and plans to open
a restaurant named after his website.
Jeter also serves as a brand development officer for Luvo Inc.
and has investment interests in multi-channel video network
company, Whistle Sports Network. He explored purchasing the
Buffalo Bills football team in 2014.
In July 2017, Jeter engaged in the bidding for ownership of the
Miami Marlins. In August 2017, Jeter and Bruce Sherman finalized
a deal to purchase the Miami Marlins. The sale was completed in
September 2017, following unanimous approval of the other 29 MLB
team owners. Though Jeter only owns a 4% stake in the franchise,
he was named chief executive officer of the team, and
controlling owner Bruce Sherman entrusted him to oversee
day-to-day operations of the team.
