On secondary markets sites such asStubHubandVivid Seats, the cheapest tickets for the sold-out stops at thehome of the 49erson Friday and Saturday, July 28-29, start at around $1,000 for the section farthest from the stage. But prices skyrocket from there.

• Taylor Swift at Levi’s Stadium:How to navigate the venue during Eras Tour concerts

As of Tuesday, July 25, seats in the 400 section, located on the stadium’s outer rim, ranged from $1,126 for a spot behind the stage to $1,770 for a spot hovering above the middle of the venue (with some costlier exceptions). That’s before the fees.

For fans hoping to get up close toSwiftduring the three-hour show, floor seats come at a premium. Prices for these coveted spots range from $2,608 for seats opposite the stage to a staggering $6,241 right up against the catwalk. Some resellers are even attempting to fetch more than $21,000 for their tickets, which were originally sold for anywhere between $49 to $449.

And they are going fast, with the inventory on offer quickly shrinking in real time.

Last month the Better Business Bureauissued a warningabout a surge of Swift ticket scams, saying that due to the unusually high demand for her Eras Tour dates, there has been an uptick in reports of people getting duped by fake passes, primarily when payments are made through peer-to-peer platforms like Zelle or Venmo.

The agency advises going through a verified reseller rather than trying to score tickets off Craigslist and social media sites or purchasing them outside Levi’s Stadium. It also warned that some scammers are hacking social media accounts to impersonate friends who are selling tickets. The BBB recommends reaching out to known acquaintances directly to ensure a legitimate transaction.

One Swift fan reported a typical ploy to theBBB Scam Tracker说,“卖家告诉我她是一个验证eller and that she was an admin in the Facebook group. The transaction took place over Zelle. After the transaction occurred, the seller failed to send me the tickets and failed to send me a refund.”

The agency recommends using a credit card with buyer protection rather than a debit card or cash transfer app for added security.

Ticket sales for the 32-year-old Grammy Award winner’s tour — her first in nearly five years —descended into chaosin November when a record-breaking presale event abruptly crashed the Ticketmaster website. The company later admitted it didn’t have enough remaining tickets to continue general sales.

Following the debacle, the Justice Department opened an antitrust investigation into Live Nation Entertainment, the owner of Ticketmaster.
