Joe Biden, on 264 electoral college votes, leads Donald Trump on 214. The winner needs 270.
Latest projections: Biden to win the US battleground states of Wisconsin and Michigan.
No projected winner yet in four battleground states (Georgia, Nevada, North Carolina, Pennsylvania) or in Alaska, a Republican stronghold. Vote counting continues in all.
Trump campaign files legal challenges in Georgia, Michigan, Nevada and Pennsylvania, and says it will seek a recount in Wisconsin.
Biden predicted victory in a speech on Wednesday night, but stopped short of an outright declaration.
Earlier, Trump called the results "phenomenal" for him, stating that he believes he has won the election, even though several states had yet to be called.
Biden has a record number of votes and three million more than Trump. But that doesn't guarantee him victory.
Trump is so far projected to win several key swing states including Florida, Texas, Ohio and Iowa.
