US stocks rallied in after-hours trading on Tuesday night and bitcoin hit a new record as Wall Street digested early presidential election results.

Futures on the Dow jumped more than 600 points, while the S&P 500 jumped by a half percentage point as early election results streamed in on Tuesday night. The US dollar index hit its highest point since July.

Cryptocurrencies, which are considered part of the so-called Trump trade, jumped on Tuesday, as well. Bitcoin surpassed $74,000, hitting an all-time high on Tuesday night. Its previous record was set in early March. Former President Donald Trump has voiced his support of cryptocurrencies in the past.

Dogecoin, the volatile cryptocurrency championed by Elon Musk, a high-profile backer of Trump, bounced more than 20% over the last day.

While Trump led Vice President Kamala Harris in early returns, several key battleground states were yet to be called Tuesday night.

Yet, with the race between Harris and Trump exceptionally tight, economists warn of potential volatility ahead, especially if results take days — or even weeks — to finalize. In 2020, it took several days to declare Joe Biden the winner, while the 2000 election between George W. Bush and Al Gore famously dragged on for more than a month.

The Dow closed 425 points higher on Tuesday, or 1%; the S&P 500 gained 1.2%; and the tech-heavy Nasdaq climbed 1.4%, all underscoring investor optimism as Americans cast their ballots.

Historically, stocks have often risen on Election Day. This marks the sixth-straight Election Day gain for the S&P 500 and Nasdaq.

“The market appears to be in an anticipatory relief rally now that the election is here,” said Louis Navellier of Navellier & Associates in a note to investors Tuesday. “While it’s still anyone’s call on where the chips will fall on the election, putting it behind in either direction is a relief.”

The prospect of a delayed or contested result could amplify market swings.

“With Election Day finally here, expect more market volatility, particularly if the wait for a result is long or contested. Political divisiveness presents a risk to investor sentiment,” said Adam Turnquist, chief technical strategist for LPL Financial.

“Though having gone through the ‘hanging chads’ of the Bush vs. Gore election in 2000, legal challenges, recounts, and the January 6 experience, perhaps markets are battle-tested for election chaos,” Turnquist added.

As results begin to pour in, sectors of the market could react differently based on the leading candidate. A Harris lead could drive gains in green energy and manufacturing stocks, given expected pushes for infrastructure spending, clean energy and social programs. However, tech and finance may face greater regulatory scrutiny. A Trump lead would favor energy, finance and industrial sectors, with investors anticipating continued tax cuts and a lenient regulatory stance, said Turnquist.
