Mark Davis is upping the ante in his bid to move the Oakland Raiders to the desert of Las Vegas.

The Oakland Raiders owner has made a $500 million pledge to push forward with the plan to build a stadium in Sin City, several media outlets have reported. The proposed 65,000-seat domed stadium will reportedly cost a cool $1.4 billion and will be built on a 42-acre lot a few blocks away from the Strip.

Davis has been working with casino operator Las Vegas Sands, along with its partner Majestic Realty, to sell the NFL stadium to the Southern Nevada Tourism Infrastructure Committee. During last week’s meeting, the stadium backers rolled out more specifics: the total private contribution will amount to $650 million—$500 million from Davies and $150 million from other partners—while the public share would be $750 million.

Las Vegas Sands President and COO Rob Goldstein told the tourism committee the stadium will give the city not only “a chance to attract an NFL franchise,” but even “bring some of the greatest events in the world that don’t come here today,” according to News3LV.
