Devils Heat

What is Devils Heat?

The extent of the revisions vary, but most are somewhat significant with regard to language that is being added or omitted. Proposed changes to Standard 9 (digital pari-mutuel systems), for instance, include mostly small additions, whereas Standard 3 (slot metering systems) has entire sections added and subtracted. Explanatory notes for the edits are frequent throughout all of the proposals.

While Nevada is considered the top gaming state in the US, its regulatory framework related to technology has been seen as slow-moving and cluttered in comparison to other up-and-coming jurisdictions around the US. Ever since NGCB Chair Mike Dreitzer took over last June, modernisation has been a top priority, and these latest revisions are an extension of that.

“We finally got to a point where we said, you know what, let’s drop all our other efforts right now and get these over the finish line and get them up for comment so that we can make sure that we’re current with things,” Jeremy Eberwein, chief of the board’s Technology Division, told iGB.

Strip away the language of contracts, order books and event trading and Bernard Marantelli has a blunt description of what is happening inside US sports prediction markets. “Kalshi is a sportsbook that’s just not allowed to have an in-house risk team,” says the founder of White Swan Data, one of the specialist firms now making markets on prediction exchanges.

The difference is all about the risk function. A sportsbook employs traders to price bets and manage its exposure. An exchange provides an API through which firms compete to quote prices and supply liquidity.

“Here’s an API. Bernard and 88 other people can market-make all these request-for-quotes (RFQs),” Marantelli says. “Some people might come in and just do esports because they’re esports experts. Others do everything. Some focus on same-game parlays. But it’s a sportsbook.”

About Devils Heat

Eilers & Krejcik Gaming (EKG) estimates that bettors will plunk down $40.5 billion on the NFL this season through regulated channels. Traditional sportsbooks are projected to capture $31.7 billion of that total, compared to a handle analog of $8.4 billion for prediction markets—a 79% to 21% split in favor of legacy operators.

Handle analog is a metric used as a cleaner comparison between sportsbooks and prediction markets because the latter’s volume doesn’t compare evenly with sportsbook handle.

Based on its projections, EKG sees the overall sports wagering industry growing 8% year-over-year, outpacing the current baseline growth rate of 5% (a figure that strips out temporary boosts from the 2026 World Cup).
