Facebook was abuzz with election comments and conversations. Twitter was a key information source for those following updates. The New York Times reported that, by 10pm local time, 40 million posts had been sent about the election.
Australian politician Pauline Hanson called the election results early, tweeting that her door would always be open to 'Mr President' Donald Trump.
Australian Prime Minister Malcolm Turnbull seemed less enthused.
US comedian Sarah Silverman tweeted 'Putin's gonna win this thing', referencing Mr Trump's admiration for Russian president Vladimir Putin.
Talkshow host Ellen DeGeneres said she supported Hillary Clinton, no matter the result.
The hashtag #Trumpaggedon began to gain traction, with some trying to find silver linings in the situation.
Social media flooded
The election day began positively for the Clinton campaign, with many polls picking Mrs Clinton as the winner and the country's first female president.
Early on, Mr Trump alleged the polls were rigged, and a senior Trump advisor was quoted as saying, "It will take a miracle for us to win."
Mr Trump's supporters remained optimistic. His daughter, Ivanka Trump, shared a photo shortly after she voted for her father, a moment she said was "surreal".
As the day progressed, and more of the US turned red, however, Mrs Clinton's supporters began to express their dismay at the prospect of Mr Trump's presidency.
