The Taylor Swift effect: Travis Kelce merch sales skyrocket

• Stubhub ticket sales for the Chiefs home games increased threefold and Kelce has more than 325,000 new Instagram followers.
• Swift's mega tour across the U.S. this year boosted the economy as fans traveled, booked lodging, and prepared for the concerts.

Driving the news: "On Sunday, Travis Kelce was one of the top 5 selling NFL players and saw a nearly 400% spike in sales throughout the Fanatics network of sites, including NFLShop.com," sports merchandising giant Fanatics told Axios in a statement.

• The Chiefs' game against the Chicago Bears on Sunday was the most-watched NFL on any network last week. It was also the most-watched game among women aged 12-49, according to Front Office Sports.

The big picture: In a 24-hour window after Swift's appearance at the game, Stubhub said ticket sales for Chiefs home games increased threefold compared to the days prior.

• Kelce's surge in popularity has extended to his social media follower count. He gained about 325,000 new Instagram followers over the past week.

• That's more than he gained after winning the Super Bowl earlier this year, Front Office Sports reported Monday.

Zoom out: The NFL has jumped on the internet hype bandwagon, changing its bio description on X, formerly known as Twitter, to "NFL (Taylor's Version)."

• The NFL also made its header photo on its X profile a picture of Swift cheering on the game while sitting next to Kelce's mother, Donna.
