More than 200 tickets were sold on the opening day of the 2018 NBA basketball playoffs, bringing the total number of tickets sold in the four-day event to more than $6 billion.
The tickets were mostly sold through lottery sites including Ticketmaster, Ticketmaster.com and StubHub.
The number of winners was not disclosed but the site said it expects to sell more than 100 million tickets.
“We are seeing record numbers of ticket buyers and are seeing more and more families coming in to buy lottery tickets for their kids and grandchildren,” said Craig Johnson, CEO of the Lottery Commission of the United States.
The lottery sites have been hit by a recent surge in ticket sales.
In September, TicketMaster.com recorded its first annual loss since the dot-com crash of 2000.
In a statement, the company said it had shut down its website to prevent the potential for further disruption.
The site is the largest seller of tickets in the U.S. and has been criticized by lawmakers and regulators.
Last year, a federal judge ruled that Ticketmaster had engaged in unfair business practices by refusing to provide refunds to consumers and by limiting the number of games offered to the public.
In June, the National Association of Ticket Distributors (NATA) urged federal regulators to block Ticketmaster from offering a lottery to the general public.
The National Association for the Advancement of Colored People also urged the Federal Trade Commission to block the company from operating a lottery site.
“The NATA strongly opposes the lottery sites and the unfair practices they engage in,” the group said in a statement.
The U.K.-based lottery site Ticketmaster was one of the first to close in May, but it continued to sell tickets on a limited basis, with tickets available online through the site.
In October, the U-K.
government announced that it was ending its participation in the site because of the company’s failure to comply with an earlier ruling by the National Lottery.
Last month, a U.C.L.A. study found that only about one-third of tickets purchased online were returned in full by the end of 2020.
