Eye-watering amount Taylor Swift has reportedly made the NFL since she started dating Travis Kelce

The 'Taylor Swift' effect is doing more than increasing friendship bracelet sales.

Wherever Swift goes, money follows. The 'Bad Blood' hitmaker wrapped up her record-breaking Eras Tour last year, which boosted most countries' economies while she was there.

According to Love Money, Swift's tour was estimated to have increased the Mexican economy by $52 million, while Australia's is thought to have seen a whopping $558 million boost.

The average Aussie-based Swiftie reportedly spend around $900 on tickets, accommodation, travel, merchandise, and dining, said Angel Zhong, an Associate Professor of Finance at RMIT University.

And it seems Swift's had a similar effect on the NFL in the wake of her ongoing romance with Kansas City Chiefs footballer, Travis Kelce.

The celebrity pair are believed to have started dating sometime in 2023 and went public with the relationship in September of that year.

Ahead of this weekend's highly anticipated Super Bowl, which will see the Chiefs go head-to-head with the Philadelphia Eagles, experts have looked into how much money Swift's frequent appearances at NFL games have injected into the American football league.

According to MarketWatch, between September 2023 to January 2024, Swift created $366,753,290 in total equivalent brand value for the NFL.

And it didn't stop there. From the day after the 2024 AFC Championship through January 27, Swift is said to have an estimated $634,304,163 in brand value.

These two figures added up come in at over $1 billion.

Speaking on the impressive amount of cash Swift has brought in for the NFL, Eric Smallwood, president of Apex Marketing Group, said: "The ‘Swift Effect’ and the corresponding media exposure continued for the NFL and the Chiefs prior to the start of the 2024 NFL season.

"The media blitz continued as the Chiefs kept winning games and were featured on national broadcasts, leading into the playoffs and now the Super Bowl."

Smallwood went on: "Taylor was visible at games, and those appearances garnered media attention from sports-media outlets and those entertainment media outlets not normally covering the NFL."

With Kelce and Swift's blossoming romance in mind, some people have hedged their bets that the sports star might propose to the singer at tomorrow's Super Bowl.

He was asked during a press conference if he plans on giving her an engagement ring, to which Kelce replied: "A Super Bowl ring? Next question."

That doesn't sound like a no to me...
