It's no surprise that Serena Williams helped sell out the women's final thanks to the history she could make by attempting to win all four major tennis titles in a calendar year. In fact, it was the first time that happened before the men's final sold out.
Now, it appears that the Serena effect has also helped push ticket prices to double in price (and at one point earlier this week they were three times as much) since the beginning of the tournament, according to data from SeatGeek, a ticket research firm. Of course, it's no lock that Williams advances to the final, as she plays Roberta Vinci of Italy in the women's semis at the tournament on Friday.
Per the company when pressed for updated information: "The median listing price for the Women's Final on our site is currently $1,186, still more than double the median listing price of a ticket before the tournament started. ($587)."
Chris Leyden, a content analyst for the firm, told Fortune, "With Serena Williams chasing the first Women's Grand Slam since 1988, it should come as no surprise that demand has continued to increase throughout the tournament."
He added that for fans who want to sit courtside, tickets are going for at least $3,000 each. Meanwhile, the get-in price for the women's final, which takes place on Saturday, is $351. Leyden expects that price to surge once again depending on if Serena makes it to the final.
Interestingly, however, the price remains less than a ticket for the men's final, which could pit Novak Djokovic against Roger Federer. According to SeatGeek, "The average resale price [for the women's final] is holding steady at $495, which is still cheaper than the Men's Final ($609) and the Men's Semifinals ($560)."
