How Trump and the U.F.C. Transformed the White House Lawn for a Fight

It was back in late May that construction began on the towering, claw-like superstructure that now sits complete on the South Lawn of the White House, ready to stage Ultimate Fighting Championship bouts on Sunday, President Trump’s 80th birthday.

The spectacle is estimated to cost more than $60 million, according to Mark Shapiro, who is the president of U.F.C.’s parent company, TKO Group Holdings. (Mr. Trump purchased between $15,000 and $50,000 worth of stock in TKO weeks ahead of this event at the White House that he has been promoting for months).

Here’s a look at the fighting arena.

The Claw

The Claw is a 600-ton steel arch built in Belgium. Jumbo-sized and star-spangled, with huge television screens hanging from every corner, it coexists strangely with the rest of its environs.

It towers over the old willow oaks and magnolia trees planted long ago by past presidents on the gentle slope of the South Lawn. It towers over the White House itself. Spectators seated in the topmost section on Sunday night will be on eye level with the Truman balcony.

The Octagon

This is the Octagon, the caged ring in which men will beat one another to a pulp.

The cage is an eight-sided feat of marketeering, its every angle prominently displaying the name of some sponsor who’d paid big bucks to have their brands juxtaposed against the ultimate backdrop.

Among them: Live Trade on Polymarket, Bud Light, Pit Boss Grills, Total Wireless, Morgan & Morgan (“Dial #Law”) and Toyo Tires. “Crypto.com” is carved into each metal step leading into the ring.

The Venue

The Claw is not all. That venue can only fit a little more than 4,000 people, so a space for a watch party capable of hosting more than 70,000 people has been set up on The Ellipse, which is the park just south of the White House gates.

Back on the White House lawn, just behind the Claw, there are large tents set up. On Saturday afternoon, the day before the fight, a crew of six motocross riders will be performing stunts on the lawn, including backflips 45 feet in the air.
