Donald Trump will become the 45th US president after a stunning victory over Democrat Hillary Clinton, the Associated Press news agency reports.
The Republican nominee’s projected victory came down to a handful of key swing states, despite months of polling that favoured Mrs Clinton.
The battlegrounds of Florida, Ohio and North Carolina cleared the way for his Brexit-style upset.
Global markets plummeted, with the Dow set to open 800 points down.
Mr Trump’s projected victory in Wisconsin put him over the 270 out of 538 electoral college votes needed to win the White House.
The US president-elect took to the stage at his victory rally in New York and said: “I just received a call from Secretary Clinton. She congratulated us on our victory.”
“Hillary has worked very hard and very hard over a very long period of time and we owe her a major debt of gratitude for her service to this country,” Mr Trump said. “Now it is time for America to bind the wounds of division.”
“It is time for us to come together as one united people.”
“I pledge to every citizen of our land that I will be president for every American. And that is very important to me,” said Mr Trump.
“For those that have chosen not to support me in the past, of which there were a few people, I’m reaching out to you for your guidance and you help so we can work together and unify our great country.”
“I expect to have great, great relationships” with other countries, Mr Trump said.
“No dream is too big; no challenge too big. America will no longer settle for anything less than the best. We must reclaim our country’s destiny and dream big and bold and daring.
“I will always keep America first,” he said.
