#Calexit is taking over Twitter, as people tweet out the hashtag call for California to leave the rest of the United States following Donald Trump’s surprise victory in Tuesday’s presidential election.

And if #Calexit actually happens, that would make California the world’s sixth-largest economy, ahead of France and India, according to 2015 data from the International Monetary Fund. Here’s exactly what that ranking would look like, if California were not part of the U.S.

Rank Nation GDP (in $USD millions) 1 United States (without California) 15,522,967 2 China 10,982,829 3 Japan 4,123,258 4 Germany 3,357,614 5 United Kingdom 2,849,345 6 California 2,424,033 7 France 2,421,560 8 India 2,090,706 9 Italy 1,815,757 10 Brazil 1,772,589

Additionally, GDP growth in California between 2014 and 2015 far outpaced other states.

There is real support behind the #Calexit movement. Hyperloop One co-founder Shervin Pishevar went on a “tweet storm” on Tuesday night to announce he would fund a legitimate campaign for California to become its own nation. Here are some of his ideas.

His tweets also received support from other prominent tech leaders, including former CEO of Cheezburger Ben Huh and entrepreneur Dave Morin.

A pro-secession website called Yes California has already popped up and is accepting donations.

“In 2016, the United Kingdom voted to leave the international community with their ‘Brexit’ vote,” the site says. “Our ‘Calexit’ referendum is about California joining the international community. You have a big decision to make.”

Texas has also made past attempts at its own #Texit. If a #Texit occurred, Texas would be the 10th biggest nation by GDP, followed by Canada and then South Korea.

Aside from secession talk, many Californians are not taking the news of a Trump victory well. High school students in the San Francisco Bay Area staged a walkout to express concern over the election of Trump.

Peaceful anti-Trump protests formed at UCLA and UC Irvine. And in Oakland, police made some arrests for disobedience and vandalism in a downtown protest.

California has voted for a Democratic majority in both chambers of the state Legislature since 1971 and has elected Democrats to the U.S. Senate since 1992.

So could California actually secede? According to Yes, California, the state could legally secede if an amendment was proposed and approved by two-thirds of the House of Representatives and Senate. If passed, it would be sent to each state legislature to be considered and would need to be accepted by at least 38 of the 50 states to be adopted.

But don’t get too optimistic. Considering amendments have only been made 17 times in our nation’s history (excluding the Bill of Rights), the odds of this happening are low.
