The longest comes from a team called Texas Triangle, who put forward a proposal that could connect Houston, Austin, San Antonio, Dallas and Laredo with 1,030 km (640 mi) of tube.
Elon Musk, CEO of Tesla Inc. and SpaceX, introduced the hyperloop idea in 2013 and encouraged people and companies to expand on it. That route would run through Columbus, Ohio. A camera stationed above the box will register what you've picked up and automatically charge your credit card, all without ever involving an employee manning the so-called store.
However, it may not be more cost efficient - Hyperloop One found that a 300-mile route between Helsinki and Stockholm would cost around $21bn.
Hyperloop creators will now work with the finalists to analyze their proposals.
Hyperloop One ultimately aims to get three full-scale hyperloop routes up and running by 2021.
A further result of the Global Challenge is a public private partnership with Hyperloop One and the Colorado Department of Transportation (CDOT), with support from AECOM, to begin a feasibility study in Colorado.
"Our successful test this summer made Hyperloop a reality, and now we're ready to bring our Hyperloop system to the world", Shervin Pishevar, co-founder and executive chairman of Hyperloop One said.
International programs include Mexico City to Guadalajara (Team Mexloop), Edinburgh to London (Team HypED), Glasgow to Liverpool (Team Northern Arc), Bengaluru to Chennai (Team AECOM India), and Mumbai to Chennai (Team Hyperloop India).
Asked why the state is taking that step before the others do, Ford said, "I think Colorado is being very progressive in how we look at innovation and bringing technology to try to improve transportation".
If granted and sufficient funds are raised, he says the track could be operational by 2020, the technology could be finalized by 2022 and the first commercial system could be in place between 2025 and 2030.
14-Boulder County, where some are still grumbling over the fizzled promise of local commuter rail, was dealt another transit-related blow Thursday morning.
The Front Range route would allow travelers to reach their destinations within minutes, the Rocky Mountain Hyperloop team said.
