The Las Vegas Convention and Visitors Authority reports there are $9bn in projects either in the planning stages or under way.
New money is coming in to take over what Union Gaming analyst Bill Lerner calls "the boneyard" of abandoned projects up and down the Strip.
"We're projecting over 40 million visitors for 2014," said Rossi Ralenkotter, president and CEO of the LVCVA. That would mark the third record year in a row.
Even so, overall spending is still only 77 per cent of what it was pre-recession. "Even when parts of the economy seem to be doing better, gaming revenues continue to falter," said Deutsche Bank analyst Andrew Zarnett.
The latest figures through November show $5.8bn in gambling revenue coming into Las Vegas Strip casinos for the year, a four per cent jump, but they remain down in the rest of Nevada.
