The ninth Democratic presidential debate is set for Wednesday in Las Vegas, and it will feature a new billionaire on the stage.

While Mike Bloomberg qualified to make the debate stage for the first time, Tom Steyer, the other billionaire in the race who's been a frequent presence at the Democratic debates, did not.

The debate is the last before the Nevada caucuses on Saturday.

The event has five moderators — "NBC Nightly News" and "Dateline NBC" anchor Lester Holt; NBC News political director Chuck Todd, moderator of "Meet the Press"; NBC News chief White House correspondent Hallie Jackson, host of "MSNBC Live"; Noticias Telemundo senior correspondent Vanessa Hauc; and Jon Ralston, editor of The Nevada Independent.

Candidates will have 1 minute 15 seconds for answers and 45 seconds for follow-ups at the moderators' discretion.

Who made the stage?

Six candidates qualified for the debate — former Vice President Joe Biden; former New York Mayor Mike Bloomberg; Pete Buttigieg, the former mayor of South Bend, Indiana; Sen. Amy Klobuchar, D-Minn.; Sen. Bernie Sanders, I-Vt.; Sen. Elizabeth Warren, D-Mass.

There were two routes to qualification — hit 10 percent in four different national polls or 12 percent in two Nevada and/or South Carolina polls, or win a pledged national convention delegate in Iowa or New Hampshire.

Biden, Sanders and Warren hit both benchmarks. Bloomberg qualified because of polling, and Buttigieg and Klobuchar got in with delegates. Steyer, who made the stage at the previous five debates, fell short on both avenues.

Where to watch the debate?

The debate will air live on NBC News and MSNBC, and it will stream live on NBC News NOW on OTT devices, NBCNews.com, MSNBC.com, the NBC News mobile app, NBC News' and MSNBC's Facebook pages and online at The Nevada Independent. It will also air live in Spanish on Universo, as well as the Noticias Telemundo mobile app and website and Noticias Telemundo's Facebook page.

When is the next round?

There are three more Democratic debates, including another one this month, ahead of the South Carolina primary Feb. 29. That debate, being held Feb. 25 in Charleston, South Carolina, is co-hosted by CBS News and the Congressional Black Caucus Institute.

The final two debates are in March and April.
