ROKT vs UFO

ROKTAState Street SPDR S&P Kensho Final Frontiers ETF

UFOCProcure Space ETF

In short

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.

UFO UFO buys the space economy through a purpose-built benchmark, VettaFi's Space Index (formerly S-Network's), holding roughly 50 companies worldwide instead of leaning on a broad aerospace-and-defense proxy.

Stated mandate

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.

UFO The fund aims to track the performance of the VettaFi Space Index, previously known as the S-Network Space Index, before accounting for fees and expenses.

Why people hold it

• 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

• UFO Rules-based, not vibes-based: exposure comes from a published space index, the VettaFi Space Index, so the roster follows index methodology rather than a manager's hunches.
• Global mandate, not a US-only roster, so satellite and launch names listed overseas are in scope.
• Roughly 50 holdings keeps the theme concentrated rather than diluted across hundreds of tangentially related names.
• A billion-dollar-plus fund that trades actively for such a narrow theme, which generally means easier entries and exits than a thin thematic sleeve. Upper half of its space peer group.

Worth knowing

• 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

• UFO 0.75% a year sits at the space-cohort median, and cheaper index routes exist: ROKT at 0.45%, ORBX at 0.50%.
• One theme, about 50 stocks. Contract wins, launch schedules and satellite demand drive the whole portfolio, so moves can be sharper than a broad global equity fund.
• Distributions arrive once or twice a year at most. This is structured as a thematic equity holding, not an income vehicle.
