ORBX vs ROKT

ORBXCGlobal X Space Tech ETF

ROKTAState Street SPDR S&P Kensho Final Frontiers ETF

In short

ORBX Space investing usually carries a 0.75% toll. ORBX charges 0.50% for a global basket of roughly 40 companies spanning launch systems, satellites, orbital transport and space tourism. The whole launchpad, not one slice of it.

ROKT Most space funds stop at the atmosphere. ROKT plays both frontiers: rockets and satellites plus the hardware that explores the deep sea, wrapped in an AI-informed S&P Kensho index running since 2018.

Stated mandate

ORBX ORBX seeks to track, before fees and expenses, the price and yield performance of the Global X Space Tech Index. It invests in companies benefiting from commercialization of the global space economy across launch systems, space technology and components, orbital transport, satellite-enabled services, and space exploration or tourism.

ROKT The fund seeks to track the S&P Kensho Final Frontiers Index, targeting companies whose products and services support innovation in outer-space and deep-sea exploration through an AI-informed, quantitative index methodology.

Why people hold it

• ORBX At 0.50%, it undercuts the 0.75% sticker worn by UFO, ARKX and NASA. Same theme, smaller toll.
• The index reaches across the whole stack: launch systems, space components, orbital transport, satellite-enabled services, exploration and tourism. Not a pure rocket bet.globalxetfs.com
• Rules-based, index-tracked and global, holding roughly 40 names. That package lands in the upper tier of the small space-ETF field.

• ROKT 0.45% a year, the cheapest sticker in this cohort: ORBX runs 0.50%, while UFO, ARKX and NASA each charge 0.75%.
• The index bolts the S&P Kensho Space Index onto the deep-sea exploration names from the Kensho Drones Index, so orbit and ocean floor arrive in one ticker.ssga.com
• Trading since 2018 under the SPDR roof, and one of the strongest implementations in the space-theme group on cost, portfolio and staying power.
• Roughly 40 stocks, refreshed on the index's annual reconstitution, with cash paid quarterly.ssga.com

Worth knowing

• ORBX Concentration cuts both ways: about 40 stocks in one young industry, so swings run wider than a broad-market fund.
• Launched in 2026, so there is little history to judge it by and the asset base is still building.
• Income is not part of the design; this is a growth theme, not a payout sleeve.

• ROKT Trades lightly next to mainstream ETFs and carries a modest asset base; wider bid-ask spreads are the usual trade-off at that size.
• Two frontiers in roughly 40 names is a concentrated slice of the market that can move very differently from a broad index.
• The deep-sea sleeve means this is not a pure space bet: part of the portfolio never leaves the water.ssga.com
