5 Fastest-Growing Space Stocks to Buy Now

1. AST SpaceMobile, Inc. (NASDAQ:ASTS)

AST SpaceMobile, Inc. (NASDAQ:ASTS) is one of the fastest-growing space stocks to buy now. On June 17, AST SpaceMobile announced the successful orbital launch of BlueBirds 8, 9, and 10 from Cape Canaveral aboard a Falcon 9 rocket. The launch is directly relevant to the growth story because the satellites expand the company’s direct-to-device broadband constellation, which is designed to connect standard smartphones without extra hardware. AST said the satellites measure about 2,400 square feet and are designed to deliver nearly double the peak data speeds of its first Block 1 BlueBird satellites.

The launch progress also gives context to AST SpaceMobile’s first-quarter growth. On May 11, the company reported Q1 2026 revenue of $14.7 million, up from $718,000 a year earlier, driven by gateway deliveries and milestone achievements. The revenue base remains early, but the latest launch keeps AST’s commercialization path tied to actual satellite deployment rather than only future network targets.

AST SpaceMobile, Inc. (NASDAQ:ASTS) is building a space-based cellular broadband network designed to connect standard mobile phones directly to satellites.
