5 Fastest-Growing Space Stocks to Buy Now

3. Intuitive Machines, Inc. (NASDAQ:LUNR)

Intuitive Machines, Inc. (NASDAQ:LUNR) is one of the fastest-growing space stocks to buy now. On May 18, Intuitive Machines announced two prime lunar reconnaissance contracts, including a $15.5 million three-year contract for Lunar Reconnaissance Orbiter Camera operations and a $4.5 million three-year contract for ShadowCam operations. The awards support imaging, data storage, analysis, mission support, lunar mapping, and observations of permanently shadowed regions of the Moon, making them closely tied to the company’s lunar data-services strategy.

The contract update fits Intuitive Machines’ broader revenue growth story. On May 14, the company reported first-quarter 2026 revenue of $186.7 million, up from $62.5 million a year earlier, while backlog reached $1.1 billion. That growth was helped by acquisitions and new awards, but the lunar reconnaissance contracts show how the company is trying to build recurring infrastructure and data services around lunar missions, rather than relying only on individual lander flights.

Intuitive Machines, Inc. (NASDAQ:LUNR) is a space infrastructure company that builds spacecraft, connects networks, and operates infrastructure-as-a-service for commercial, civil, and government customers.
