"Yes, I'm making a movie to get us out of this mess," the award-winning provocateur said on Twitter alongside a link to an article about the film on Variety magazine's website.
According to the site, film producers Bob and Harvey Weinstein have acquired the global rights to the film through one of their companies, Fellowship Adventure Group, which produced Moore's "Fahrenheit 9/11."
When contacted by AFP, The Weinstein Company, the Weinstein brothers' US film studio, said they were unable to comment.
The name of the leftist filmmaker's latest documentary stems from the date the results of last year's presidential election were finalized, November 9, 2016. The vote itself took place the day before.
It comes more than a decade after Moore first shot to fame with "Fahrenheit 9/11," a political documentary about the presidency of George W. Bush in the aftermath of September 11 and the wars in Afghanistan and Iraq. The film earned him the Palme d'or prize at the Cannes film festival in 2004.
During the 2016 presidential election, Moore sought to mobilize public opinion against Trump and was one of the very few public figures to say the then-candidate stood a strong chance of winning.
Three weeks before the election, he rushed out a surprise documentary, "Michael Moore in Trumpland," an ode to Democratic candidate Hillary Clinton that he made in just 12 days.
In late July, the 63-year-old -- also known for lambasting capitalism, large corporations and assault weapons -- will make his debut on stage in the US with a one-man-show on Broadway that returns to the theme of Trump's rise to the White House.
