I'm escaping to the one place that hasn't been corrupted by capitalism: Space!

Actor Tim Curry's character said that in a campy 2008 video game, a quote that later became a popular meme. But, sorry Tim, space is now most definitely a focal point for industry, and there are a burgeoning number of exchange-traded funds investing in a range of up-and-coming space technology companies. Ahead of the initial public offering for SpaceX, which is expected to be the biggest in history, a handful of ETFs have gotten exposure to the company. And others, with or without SpaceX, have added or prepped space tech funds. GlobalX, for example, considered the timing of Elon Musk's forthcoming IPO, though the company's new ETF invests much more broadly in the space theme. The company's research showed that there were enough public companies with at least 50% of their revenues tied to space technology to build a pure-play fund, said Lis Agosto, director of product research and strategy at the firm. That fund, the Global X Space Tech ETF (ORBX) launched just over a week ago.

"We've been monitoring the space sector for quite a bit," she said. "We felt that this was the right time."

That fund has 28 holdings, with the largest being in Rocket Lab, Planet Labs, AST SpaceMobile and Firefly Aerospace. It's focused on companies that stand to benefit from the commercialization of the global space economy, including those developing rocket launch systems, mission-critical tech, space tourism and other subcategories. Although there are a few space ETFs on the market, others are on the way. WisdomTree filed late last week with the Securities and Exchange Commission for its Space Economy Fund, and First Trust is prepping its Bloomberg Space Economy ETF.

The existing funds on the market show some of the potential demand:

SpaceX Everywhere: Whether or not index fund investors like it, they will very likely soon have significant exposure to SpaceX, as it may be one of the largest public companies. That may make some investors wonder if their broad-market funds give them a good taste of the space economy. "One of the questions we often get is, 'If I buy SpaceX when it IPOs, do I own the theme?' And the answer is 'no,'" Agosto said. Globax X's new fund, which is passive, allocates to much smaller companies than investors will find in the big index funds, she noted. "To us, a basket approach makes sense," she said. "We're letting the winners play [out] over time."
