10 Fastest-Growing Space Stocks to Buy Now

7. Redwire Corporation (NYSE:RDW)

Redwire Corporation (NYSE:RDW) is one of the fastest-growing space stocks to buy now. On June 4, Redwire said it won a contract from Astrobiome Space to launch its first space agriculture mission using Redwire’s Greenhouse system on the International Space Station, described as the world’s first commercial space greenhouse. The mission will grow strawberries and test Astrobiome’s soil-enhancement product, giving Redwire another customer use case for microgravity research and life-support technologies. For this growth screen, the relevance is less about the undisclosed contract size and more about how the award extends Redwire’s infrastructure base into commercial biological research.

The award sits on top of a stronger first-quarter growth profile. On May 6, Redwire reported first-quarter 2026 revenue of $97.0 million, up 57.9% year over year, with a record backlog of $498.1 million and a 1.92 book-to-bill ratio. Gross margin improved to 26.6%, although the company remained unprofitable. The growth case is tied to rising contract activity across space infrastructure and microgravity research.

Redwire Corporation (NYSE:RDW) is an integrated space and defense technology company that provides space infrastructure, autonomous systems, microgravity research platforms, deployable structures, sensors, and related mission-critical technologies.
