The U.S. Open is in its final weekend. A men’s champion will be crowned on Sunday, with Roger Federer taking on Novak Djokovic in a battle between the top two players in the world.
The tournament takes place at the USTA Billie Jean King National Tennis Center in Flushing, Queens and the event reportedly brings $750 million to the New York City economy, according to several studies. What goes into that substantial sum?
The most recent study of the U.S. Open’s economic impact, which was performed by consulting firm AKRF in 2010, “found that the tournament generates approximately $756 million in direct revenue for the tri-state area—more than any other sports or entertainment event in any city in the United States,” according to a spokesperson from the United States Tennis Association.
“We think that … has probably exceeded $800 [million] at this point,” said USTA Chief Operating Officer Danny Zausner during an interview with Fortune at his office inside Arthur Ashe Stadium, the U.S. Open’s biggest show court, which boasts a 17,000 fan capacity. “We know that the two main factors for that are 16% of fans are coming from international locations and, in total, 40% of fans are coming from outside of the tri-state area.” That means tennis fans spend several days in New York City, stay in hotels, eat at local restaurants, and, of course, fly in and out of the state.
The U.S. Open employs 7,000 seasonal workers to ensure the event runs smoothly. These people hold jobs in food services, security, and ticketing. Also factored into the tournament’s economic earnings: transportation to and from the event, including those taking the 7 train and paying Metro Card fares and paying for Long Island Railroad tickets. Some 60% of the more than 700,000 fans that attended in 2014 took public transportation. Then there’s money paid to the state via sales tax, rent to the city, and construction, which includes an ambitious $600 million project to expand the grounds.
Looking back and forward
This year’s event marks the 100th year since the first tournament was played at the Westside Tennis Club, the predecessor to the current location, although there was a tournament first played for men in 1881.
Along with the grounds expansion at the U.S. Open, the USTA has ambitious plans to construct a new office in Orlando, Florida, moving away from the current location in White Plains, New York. The USTA is calling it the “new home for American tennis,” and it will include a facility with over 100 tennis courts where the organization’s player development and community tennis departments will be based. It’s scheduled to be built during the fourth quarter of 2016. The project is a collaboration with Tavistock Group, a private investment company.
The new facility couldn’t come at a better time for the USTA, which has been struggling to boost the number of active players, especially among youth.
So, it looks like the USTA is set to have one foot in New York and the other in Florida, following in the footsteps of many of the organization’s elderly Queens neighbors. “We’re investing quite a bit of money to transform the home of the U.S. Open over the next five years to become the greatest tennis center in the world. With Lake Nona, we see that being the home of American tennis,” said Dave Haggerty, former chief executive of the USTA. “But the Open has a cherished history here in New York and with the investments were making, certainly the Open continues. But the training for a lot of Americans who may be playing at the Open, or in junior events, or national events, can take place in Lake Nona.”
