Joe Biden is leading Donald Trump in the state of Pennsylvania.
If the former vice president goes on to win the battleground state - which is worth 20 electoral votes - he will have surpassed the 270 Electoral College votes required to carry the White House.
The Democratic candidate holds a nearly 6,000-vote advantage.
Associated Press has said that the contest is still too early to call as votes are still being counted.
However, Decision Desk HQ has projected that Mr Biden has won Pennsylvania.

Democrat Joe Biden is now leading President Donald Trump in the battleground state of Georgia.
Victory in the state would take him over the 270 threshold of electoral college votes needed to win the White House.
By Friday morning, Mr Biden overtook Mr Trump in the number of ballots counted in the battleground, a must-win state for Mr Trump that has long been a Republican stronghold.
Mr Biden now has a 1,097-vote advantage.
The contest is still too early for The Associated Press to call.
Thousands of ballots are still left to be counted, many in counties where the former vice president was in the lead.
An analysis showed that Mr Biden’s vote margins grew as counties processed mail ballots cast in his favour.
There is a potential that the race could go to a recount.
Under Georgia law, if the margin between Mr Biden and Mr Trump is under half a percentage point of difference, a recount can be requested.
