"I am pleased to say preparations are running on schedule," Liberty Media CEO Greg Maffei said in a call with Wall Street analysts.
"Despite inflationary cost pressures, we expect no change in revenue and profitability assumptions that we laid out previously. We are increasing CapEx [capital expenditure] estimates for the paddock building and track work.
"We remain confident in the return profile of this incredible project, which will support the incremental capital investment that we are making."
Liberty's chief financial officer Brian Wilding revealed the paddock building is 85 per cent complete, with an overall outlay of around $400m expected.
Ahead of the race, Red Bull boss Christian Horner shared his excitement.
"That race is going to be insane," Horner said. "I've never known so much hype around a sporting event as a race on Saturday night down the Strip in Las Vegas.
"Everybody I meet says 'oh, I want to be in Vegas.' That weekend will be insane."
