Rose filed paperwork with the campaign finance board in December to begin raising money for a possible run.
However, on Sunday morning, Rose announced via Twitter that he will not be a candidate looking to succeed current NYC Mayor Bill de Blasio.
Rose said he will not be going anywhere in the fight to make NYC and the United States live up to their promise.
"I urge every candidate to recognize that across the five boroughs no one believes that City Hall is on the side of the working class. People are scared and unsure if the New York they love will still exist in the years to come. The next mayor can't just balance the budget, he or she must build a social contract that leaves no one behind. New York City can set the governing example for the rest of the world," Rose said in a statement.
The congressman lost to Republican Nicole Malliotakis in a highly contentious race for the New York district that includes Staten Island.

Just weeks ago, former Democratic presidential candidate Andrew Yang filed paperwork with New York City's Campaign Finance Board, indicating he has formed a mayoral campaign committee and is exploring a run.
That follows Brooklyn Borough President Eric Adams throwing his hat in the ring.
Other possible names running for the spot include former de Blasio chief council Maya Wiley, former sanitation commissioner Kathryn Garcia, former Bloomberg and Obama administration member Shaun Donovan, former nonprofit executive Dianne Morales, former Veterans' Services Commissioner Loree Sutton, and former Citigroup executive Ray McGuire.
