Joe Biden has won battleground New Hampshire while US President Donald Trump leads in all-important Florida.
New Hampshire was the first swing state called by NBC News while the others remain too close or too early to call.
Trump was leading Biden in Florida with 51.2 percent to 47.8 percent with 94 percent of the expected vote in.
North Carolina is a neck-and-neck race with 49.8 percent for Trump and 49.0 percent for Biden with 89 percent of the expected vote in.
In Texas, a conservative stronghold that became surprisingly competitive, Trump was ahead 51.1 percent to 47.5 percent with 80 percent of the expected vote in.
But Biden leads in Arizona, where the Democrat had 53.7 percent to Trump's 45 percent with 75 percent of the expected vote in.
The critical Rust Belt states like Pennsylvania and Michigan are expected to be slower to count and release results.
In Florida, Biden is underperforming Hillary Clinton in Miami-Dade County, the state's biggest and home to a large Cuban-American community that Republicans had targeted.
But Biden is running better than Clinton did in 2016 in other counties.
Trump has to win Florida to have any real shot at re-election, most analysts agree, while Biden has multiple paths to victory that do not include the state, his campaign aides have noted, such as winning back Upper Midwest states Trump flipped four years ago and where Biden has been leading in polls.
After millions of door-knocks, TV ads and a record-shattering $14 billion spent, a tense and stressed-out nation is waiting for the results an unprecedented presidential election to see whether Trump will get another four years in the White House or be replaced by his Democratic challenger.
Polls have now closed in all of the 13 swing states where the presidency will be decided: Arizona, Florida, Georgia, Iowa, Michigan, Minnesota, New Hampshire, Nevada, North Carolina, Ohio, Pennsylvania, Wisconsin and Texas.
Early NBC News exit polls show the economy, racial justice and Covid-19 are top concerns while the vast majority of voters said they made up their minds a while ago and just four percent said they decided whom to vote for in the past week, down from 13 percent who were late-deciders in 2016.
