"In the end, I believe that we will win", he wrote. Now it's time to bring Florida together'. "I remain humbled by your support and the great honor the people of Florida have shown me as I prepare to serve as your next governor", he said in his statement, inviting Gillum "to join me in the days ahead in a conversation about the future of our great state". More than 8 million voters cast ballots in the race.
Mr Gillum, who was attempting to become the state's first black governor, had vowed to keep in the race until every single vote was counted.
Gillum was still trailing DeSantis by 33,683 votes, according to the official recount.
But by Thursday's 3 p.m. deadline, when the results of a statewide machine recount were due, DeSantis still maintained a margin wide enough to avoid triggering a further manual recount, essentially ensuring his status as governor-elect.
If that line earned Gillum viral praise and national recognition, his indirect connections to an FBI investigation into public corruption in Tallahassee was a drag on his campaign, which at times struggled to explain Gillum's relationship with a former lobbyist and friend and his run-ins with an undercover federal agent.
After Gillum initially conceded the contest on election night, his subsequent calls for every vote to be counted echoed similar appeals from fellow Democrat U.S. Senator Bill Nelson.More news: Pilots unions criticise Boeing for withholding safety information

Trump has repeatedly charged that Florida's elections were marred by vote fraud, but state and local authorities have said there is no evidence of wrongdoing.
Both parties and their supporters filed multiple lawsuits challenging the process, with Republicans urging a strict standard on which votes were counted while Democrats contested rules that they saw as disenfranchising voters.
"This was not just about an election cycle". Snipes did insist that the ballots were still in the elections building.
Counties across the state are in the middle of a hand recount for two statewide races including the race for U.S. Senate. Once that recount was complete, if the differences in any of the races are 0.25 percentage points or less, a hand recount is ordered.
