Roundhill Investments launched its Space & Technology ETF (MARS) on March 5, 2026, targeting companies directly tied to the growth of the commercial space economy. The actively managed fund aims to provide investors with concentrated exposure to pure-play space firms focusing on launch, satellite operations, and space-enabled data services.

As of the ETF’s inception, the top three holdings are Rocket Lab (10.33%), AST SpaceMobile (9.99%) and EchoStar (8.99%), while Planet Labs (5.59%), Globalstar (5.48%) and Viasat (5.12%) round out the top six. The fund holds ten primary space-related names, with individual weights ranging from 3.98% to 10.33%, and is non-diversified to maintain focused exposure.

Industry analysis forecasts the global space economy to grow from $630 billion in 2023 to $1.8 trillion by 2035, driven by declining launch costs, expanded satellite networks and rising demand for space-based data. This projection underscores long-term opportunities across the space value chain, including commercial launch services, satellite broadband and geospatial intelligence.

Investors should note risks inherent to space and technology companies, including reliance on government spending, supply chain disruptions, cybersecurity threats and rapid obsolescence. Additional risks stem from concentrated sector exposure, emerging-market volatility and intensive capital requirements characteristic of aerospace and satellite businesses.
