Musician Taylor Swift and NFL star Travis Kelce got married over the weekend, hosting a celebration with nearly 1,000 friends and family at Madison Square Garden. While the event itself won't move the needle for Madison Square Garden Entertainment (MSGE), the venue's owner, the real financial story might be what happens next: a potential film or docuseries about the wedding.

Swift has a track record of turning her life into content. Her concert film, "Taylor Swift: The Eras Tour," grossed $267 million worldwide in partnership with AMC Entertainment Holdings (AMC). Now, signs suggest the wedding was also captured on camera. Entertainment Weekly reported that signs at Madison Square Garden indicated a film shoot was in progress, and guests were told they would be filmed. Tight non-disclosure agreements banned cell phones at the reception, meaning the only footage likely belongs to Swift and Kelce's own camera crew.

So what happens to that exclusive footage? The couple might just want a personal keepsake, or they could release it as a wedding favor. But the more likely scenario is that the event was filmed with an eye toward a theatrical or streaming release—a movie or docuseries that could be huge.

If that happens, the big question is: who gets the rights? Swift has two obvious partners. AMC helped launch the Eras Tour film into theaters worldwide, making it a natural fit for a wide theatrical release. On the streaming side, Walt Disney Co (DIS) landed the streaming rights to that concert film and also produced the six-episode "Taylor Swift: The End of an Era."

Both companies had a presence at the wedding. According to Variety, several Disney executives were on the guest list, including former CEO Bob Iger, Head of Live Action Films David Greenbaum, and Disney President Dana Walden. That doesn't mean they were there to oversee filming, but it shows how close Disney has become to Swift—she even sang an original song for the recently released "Toy Story 5."

AMC CEO Adam Aron also attended and shared a lengthy account of the event in a since-deleted social media post, as reported by Deadline. "It was such a privilege to be THERE," Aron tweeted. Some of the details he shared may have gone beyond what the happy couple wanted public—and might have violated the spirit of the NDAs. Time will tell if that deleted post hurts AMC's chances of landing the rights.

For now, investors can watch both AMC and Disney as potential beneficiaries of whatever comes next. Whether the wedding ends up in theaters or on streaming, the Swift-Kelce brand is a powerful one—and the company that partners with them could see a nice boost.
