Overview
PPA is a broad aerospace and defense equity ETF with $7.64B in assets, tracking established defense contractors and suppliers across the industry. XSPC is a thematic space-economy ETF launched 06/15/2026 with $2.12M in assets, focused on companies involved in space infrastructure and commercial space activities. The fundamental difference is scope: PPA captures the legacy defense industrial base, while XSPC targets emerging commercial space ventures.
How they differ
PPA holds diversified aerospace and defense names—the established, capital-intensive contractors that dominate government spending. XSPC concentrates on companies engaged in space technology, launch services, satellite communications, and related space-economy themes, a narrower and newer sector. PPA's 0.58% expense ratio is 17 basis points cheaper than XSPC's 0.75%, and PPA's $7.64B in assets dwarfs XSPC's $2.12M, reflecting the difference between an established large-cap fund and a micro-cap thematic play. PPA carries a 0.86 beta, indicating less sensitivity to broad market swings than an index with a beta of 1.0.
Who each is best for
PPA: Fits investors seeking steady exposure to aerospace and defense as a core industrials holding, comfortable with mature, government-contracting-dependent businesses and modest dividend income.
XSPC: Designed for investors pursuing concentrated thematic exposure to commercial space development and orbital economy growth, willing to accept micro-cap liquidity constraints and no current income in exchange for sector specificity.
- Government spending dependency for PPA. Defense contractor revenues hinge on federal budget cycles, budget battles, and geopolitical shifts. A major reduction in defense appropriations would pressure valuations across the portfolio.
- Commercial space viability for XSPC. Most companies in the space-economy theme are early-stage or unprofitable. Business models for satellite internet, space tourism, and in-orbit manufacturing remain unproven, and competitive pressures from larger technology firms are rising.
- Sector overlap and valuation divergence. Both funds include space-related holdings, so their returns may track together during space-sector rallies but diverge sharply if commercial space falters while traditional defense spending holds steady—or vice versa. If you're pursuing concentrated bets on the emerging commercial space industry and can tolerate micro-cap volatility and illiquidity, XSPC's focused mandate aligns with that thesis. Verify holdings overlap before combining them, and remember that past performance in either space or defense does not predict future results.
