NASA ETF Holdings: Guide to Space Industry Stocks

SpaceX's Starship completed its eighth orbital test flight in May 2026, marking a milestone that sent shockwaves through aerospace investment portfolios. Institutional and retail investors watching NASA ETF holdings noticed immediate portfolio shifts as exposure to commercial space vendors tightened. The convergence of federal spending, private innovation, and public market appetite has turned space exploration from a niche sector into mainstream investment territory.

Exchange-traded funds focused on space and aerospace have grown substantially since 2024. These funds track companies contracted to NASA, the Department of Defense, and emerging private spaceflight operators. Investors seeking investing in space now have multiple vehicles, each with distinct holdings and strategic weightings.

Core Holdings in Space-Focused ETFs

The largest space ETF products maintain concentrated positions in a handful of established defense contractors and emerging aerospace firms. Boeing Defense, Space and Security remains a significant holding, despite ongoing quality and schedule challenges in its NASA contracts. Lockheed Martin, Northrop Grumman, and Raytheon Technologies anchor the traditional aerospace segment.

Newer entrants command growing allocations. Companies including SpaceX (where available through secondary markets or parent company exposure), Axiom Space, and Relativity Space appear in thematic fund prospectuses. Smaller suppliers like Intuitive Machines, which landed lunar cargo for NASA in February 2024, have become fixtures in sector-specific portfolios.

David Rubenstein, chairman of The Carlyle Group, stated in an April 2026 aerospace conference: "The space economy is no longer speculative. We are seeing institutional capital flow into sustainable, contract-backed businesses that serve NASA and commercial customers alike."

• Lockheed Martin - navigation systems, launch vehicles, lunar infrastructure
• Northrop Grumman - satellite systems, missile defense, orbital servicing
• Boeing Defense - Starliner crew transport, SLS core stage production
• Collins Aerospace - life support, avionics, pressurized modules
• Axiom Space - commercial space station modules and services
• Relativity Space - 3D-printed rocket components

Why NASA Contracts Drive Valuations

NASA stock exposure through ETFs is fundamentally tied to government procurement. The 2026 fiscal year allocated $28.4 billion to NASA operations, a 3.2% increase from 2025. Approximately 18% of that budget flows to commercial partners and contractors, translating into multi-year revenue visibility for portfolio companies.

The Artemis program alone commits $10+ billion annually through 2030, supporting lunar lander development, spacesuit manufacturing, and life-support systems. These are fixed-price development contracts, reducing commodity-like volatility that plagues some sectors. Contract awards and milestone payments create predictable cash flows that institutional investors prize.

Commercial space station development accelerates as the International Space Station approaches the end of its operational window. Companies building orbital habitats and docking modules for both government and private clients benefit from dual revenue streams. Aerospace stocks exposed to this transition showed 12-18% gains in the first quarter of 2026.

How to Access Space Industry Returns

ETF holdings allow retail investors to own fractional interests in aerospace supply chains without buying individual stocks. The Procure Space ETF (UFO), launched in 2021, holds approximately 40 companies with average weighting around 2-3% per position. The ARK Space Exploration and Innovation ETF (ARKX) maintains a more concentrated portfolio of roughly 35 holdings, with positions exceeding 5% for core bets.

Expense ratios typically range from 0.65% to 0.75% annually, moderate compared to actively managed mutual funds. Most offer daily liquidity and can be held in standard brokerage accounts, 401(k) plans, and IRAs. Share prices reflect intraday space industry sentiment, with significant swings around NASA announcements, launch schedules, and earnings reports.

Performance varies by fund strategy. Broad aerospace exposure funds returned 8.3% year-to-date through May 2026, slightly outpacing the S&P 500. Concentrated thematic space funds showed wider ranges: some up 18% while others lagged by 2-3%, reflecting different bets on startups versus established contractors.

Prospective investors should review each fund's prospectus to understand concentration risk, expense structure, and exposure to international suppliers. Some ETFs include companies like Airbus and Arianespace, adding European aerospace diversification. Others focus exclusively on US-domiciled firms with direct NASA relationships.

The space investment landscape in 2026 reflects maturation of what was once speculative. Government commitments, private capital deployment, and technological breakthroughs have created a durable industry segment. Whether accessed through individual stock selection or pooled ETF vehicles, aerospace and space exposure now occupies a recognized place in diversified investment portfolios.
