In order to take part in the Nevada debate, he had to poll above double digits in four national polls recognized by the Democratic Party.
On Tuesday, an NPR/PBS NewsHour/Marist poll found he had support from 19% of those surveyed, BBC reported.
The ex-New York mayor is not competing in the first four nomination contests.
Bloomberg, 78, has instead chosen to enter the race on March 3, known as Super Tuesday, when 14 states will vote.
He came in second place in the NPR/PBS NewsHour/Marist poll. Bernie Sanders came in first with 31% support nationally and Joe Biden was in third place with 15%.
"Mike is looking forward to joining the other Democratic candidates on stage and making the case for why he's the best candidate to defeat Donald Trump and unite the country," Bloomberg's campaign manager Kevin Sheekey said in a statement.
Billionaire businessman Bloomberg has spent hundreds of millions of dollars on television, radio and digital advertising for his campaign.
According to CNN, he has a campaign operation involving more than 2,000 aides in New York and across the country.
Bloomberg has been accused by rival candidates Elizabeth Warren and Bernie Sanders of trying to buy the election. He has denied the claims and has offered to fund the Democratic effort to beat Republican President Donald Trump even if he does not win the nomination.
During a Democratic dinner in Nevada on Saturday, Sanders said: "I got news for Mr. Bloomberg, and that is the American people are sick and tired of billionaires buying elections."
During the debate Bloomberg is expected to face tough questions over some of his policies as mayor.
He was criticized over his support for the "stop and frisk" policy that saw a disproportionate number of black or Latino people questioned and searched by police officers.
He has issued apologies, however Joe Biden has vowed to challenge him on the policy.
Democratic candidate Amy Klobuchar said she thought Bloomberg should be on the debate stage. She told NBC's Meet the Press: "He can't hide behind the airwaves. He has to answer questions."
