Key Highlights

  • The anticipated public listing of the world's leading private launch operator represents a potential re-rating event for all three ETFs covered in this report, each via a structurally distinct mechanism.
  • UFO carries the highest probability of forced inclusion at maximum weighting due to its narrow space-Revenue index methodology; it is the most direct proxy available to public market investors today.
  • ARKX offers active management flexibility that allows day-one Acquisition of IPO shares without index rebalance lag, complemented by retail sentiment dynamics that have historically amplified NAV moves in ARK products.
  • ITA provides the broadest Liquidity and the most conservative entry point, with inclusion justifiable on defence contract revenue classification once the company lists above material AUM thresholds.
  • In our assessment, smart institutional money is already rotating into these vehicles as positioning proxies; historical precedents from comparable high-profile private-to-public transitions support this read-across.

Executive Summary

The prospective public listing of the world's most valuable private aerospace company — and separately, the potential listing of its broadband satellite division — constitutes what our analysts regard as the single most anticipated IPO catalyst in the space economy sector since the commercial launch industry emerged as an investable theme. For investors who cannot access the company through secondary private market channels, three Exchange-traded funds currently listed on US exchanges offer structurally differentiated exposure pathways: UFO, ARKX, and ITA.

This report assesses each fund across five dimensions: index methodology and inclusion probability, portfolio construction and current holdings, AUM and liquidity characteristics, active-versus-passive management implications for IPO-day positioning, and the price impact mechanism through which the catalyst would transmit into fund performance. We assign Morningstar Analyst Ratings of Bronze to UFO and ITA, and a Neutral rating to ARKX, reflecting the differences in process quality, fee structure, and Risk-Adjusted Return potential over a full Market Cycle — independent of the IPO catalyst discussed herein.

UFO — Procure Space ETF: The Pure-Play Candidate

Fund Overview and Index Methodology

UFO tracks the S-Network Space Index, a rules-based benchmark that requires constituent companies to derive a meaningful and verifiable proportion of their revenue from space-related commercial activities. The index's narrow mandate — launch services, satellite Manufacturing and operations, ground systems, and related enabling infrastructure — makes it structurally the most likely vehicle to include the target company at a material weighting upon any public listing.

The mechanics are important to understand. Passive Index Funds do not exercise discretion over inclusion. When the index rules are satisfied — typically a combination of Capitalisation/">Market Capitalisation threshold, liquidity screen, and revenue classification — the fund's authorised participants will execute buy orders to bring the portfolio into alignment with the revised benchmark. Given the commercial launch Market Share commanded by the company in question, revenue classification as space-derived is not in doubt. The question is purely one of timing and market capitalisation eligibility, both of which a successful IPO would immediately resolve.

Portfolio Construction and Current Holdings

In its current composition, UFO holds a concentrated set of publicly listed space-economy names spanning satellite operators, earth observation companies, and launch-adjacent infrastructure providers. Names including Iridium Communications, SES Global, and Maxar Technologies represent the fund's current expression of the space revenue theme. These are solid, if largely mature, businesses. The addition of a company with the growth profile, revenue scale, and market share dominance of the anticipated listing would represent a qualitative step-change in the fund's underlying Earnings power.

The current weighting structure also means that a high-market-cap entrant would necessarily displace existing holdings, compressing their weights and concentrating the fund in the new addition. For investors entering UFO as a pre-IPO positioning vehicle, this concentration effect is a feature rather than a bug: it means that a successful listing translates directly into a significant portfolio event.

AUM, Liquidity, and the Amplification Effect

UFO is a small fund by conventional AUM standards. This has two implications that cut in opposite directions. First, the lower the AUM, the greater the price-impact of large inflows relative to the underlying NAV. If retail and institutional investors pour Capital into UFO in anticipation of the index inclusion, the ETF's Market Price can trade at a premium to net asset value — a dynamic that has been observed in thematic ETFs during periods of concentrated speculative interest. Second, lower AUM means that the fund's ability to absorb the index-mandated purchase of a large-cap new entrant is constrained relative to a larger fund; authorised participant creation activity may be elevated.

Our Morningstar Bronze rating for UFO reflects the strength and clarity of its index methodology, offset by concerns about the fund's expense ratio relative to peers and the concentration risk inherent in a narrow thematic mandate. On a standalone, cycle-neutral basis, UFO is a reasonable vehicle for investors who believe in the long-term commercialisation of the space economy. The IPO catalyst, if it materialises, represents a non-recurring upside event layered on top of that base thesis.

ARKX — ARK Space Exploration and Innovation ETF: The Active Flexibility Play

Fund Overview and Active Management Mandate

ARKX is an actively managed ETF operating under the Investment framework developed by ARK Investment Management. Unlike UFO and ITA, it is not bound by an index methodology or a quarterly rebalance schedule. The Portfolio Management team can acquire newly listed shares on the first day of trading, respond to intraday price movements, and build a position at any weighting they deem appropriate — unconstrained by the passive mechanics that govern the other two funds covered in this report.

This flexibility is the fund's primary structural advantage in the context of a high-profile IPO. In the scenario where the target company lists and Demand from institutional investors creates an allocation shortage in the book-build, actively managed funds that participate in the IPO allocation process may receive shares at the Offer Price before retail investors can access the Secondary Market. ARK's track record of participating in high-profile technology listings, and the public commentary from the firm's investment team regarding the transformative potential of the commercial space and satellite broadband industries, makes ARKX a natural candidate for early and aggressive positioning.

The Retail Sentiment Layer

ARK funds carry a retail following that is, in our assessment, unique among ETF managers in terms of its engagement intensity and responsiveness to holdings disclosures. ARK publishes its daily portfolio transactions publicly, and the disclosure of a significant new position — particularly one as anticipated as this — generates retail inflows that are not fully explained by the underlying NAV change. This creates a reflexive dynamic: ARK buys the stock, discloses the holding, retail investors buy ARKX, ARKX premiums expand, which further validates the thesis in the retail investor community.

This dynamic has been observed in ARKX previously and is not a speculative assertion. It is a repeatable behavioural pattern associated with the ARK Brand. For investors who understand it and position accordingly — entering ARKX before the disclosure rather than after — it represents a return source that is distinct from the fundamental case for the underlying holding.

Morningstar Neutral Rating: Process Quality Considerations

Our Neutral rating on ARKX reflects concerns that are separate from the IPO catalyst discussion. The fund's expense ratio is elevated relative to index-based alternatives. Its historical tracking of the space economy theme has included periods of significant drawdown driven by holdings outside the core thesis. And the active management process, while flexible, introduces manager concentration risk that passive vehicles do not carry. Investors should weight these structural characteristics appropriately alongside the tactical opportunity that the anticipated listing represents.

ITA — iShares U.S. Aerospace and Defense ETF: The Liquid Large-Cap Pathway

Fund Overview and Index Methodology

ITA tracks the Dow Jones U.S. Select Aerospace &Amp; Defense Index, a market-capitalisation-weighted benchmark covering US-listed companies in the aerospace and defence industry. Its current holdings include the largest US defence contractors and aerospace primes, including companies involved in missile systems, avionics, aircraft manufacturing, and government services. It is the most liquid and largest-AUM fund among the three covered in this report.

The investment thesis for ITA as a SpaceX listing proxy rests on a revenue classification argument. The anticipated listing candidate derives a substantial and well-documented proportion of its revenue from US government contracts — Department of Defense launch services, national security satellite delivery missions, and related government programmes. This revenue profile satisfies the index's classification criteria for aerospace and defence exposure, and at the market capitalisation expected at listing, the company would likely enter the index as a top-five constituent by weight.

The Classification and Timing Question

The principal uncertainty for ITA inclusion is classification timing rather than eligibility. The Dow Jones index methodology applies standard GICS (Global Industry Classification Standard) coding, and the GICS committee's assignment of an aerospace and defence classification — as opposed to a technology or industrials classification — will determine which index and therefore which ETF receives forced buying. Our base case is that the defence contract revenue weight tips the classification toward aerospace and defence, but this is not guaranteed and represents the primary inclusion risk for the ITA thesis.

For investors who prefer the liquidity profile and lower Volatility of a large-cap aerospace and defence fund over the more concentrated, smaller-AUM alternatives, ITA offers the most conservative entry point among the three Options. The IPO upside is less amplified than UFO's, and the active timing advantage is absent relative to ARKX, but the lower tracking error and tighter bid-ask spreads make it a more appropriate vehicle for institutional-size positions.

Morningstar Bronze Rating

Our Bronze rating for ITA reflects the fund's strong process quality, competitive expense ratio, and well-established index methodology. On a standalone basis, ITA is among the more efficiently structured sector ETFs in the US Equity universe. The IPO catalyst adds a non-base-case upside scenario that could result in a material short-term re-rating, particularly given the fund's size and the corresponding scale of index-mandated purchases that a large-cap addition would require.

Comparative Analysis: Which Fund Best Fits Your Objective?

The three funds are not mutually exclusive, and they serve different investor objectives within the same thematic thesis. The following framework may assist investors in determining appropriate allocation:

For maximum IPO sensitivity with concentrated space exposure: UFO. The index methodology virtually guarantees inclusion, the small AUM amplifies inflow effects, and the narrow mandate means the new entrant would represent the single most important holding in the portfolio. The trade-off is higher expense ratio and limited Diversification.

For day-one positioning flexibility and retail sentiment Leverage: ARKX. Active management removes the rebalance delay, the ARK disclosure dynamic creates a retail inflow Kicker, and the portfolio management team's publicly stated conviction in the space economy thesis makes early and meaningful positioning likely. The trade-off is higher management fees and manager concentration risk.

For institutional-size, liquid exposure with a conservative risk profile: ITA. The largest AUM, tightest spreads, and most established index process make it the appropriate vehicle for investors who want category exposure without the volatility amplification of smaller thematic funds. The trade-off is a more diluted thesis and classification uncertainty at the point of index reconstitution.

Historical Precedents: What Prior Large-Scale IPOs Tell Us

Investors assessing the plausibility of pre-IPO ETF re-ratings have several historical analogues to draw on. In each case, ETFs with clear mechanical exposure to a forthcoming high-profile listing experienced speculative inflows ahead of the event, followed by index-driven mechanical buying at the time of inclusion.

The pattern observed in ride-sharing sector peers ahead of major platform company listings, in hotel and travel ETFs ahead of the major home-sharing platform's public debut, and in electric vehicle ETFs ahead of the Chinese EV manufacturers' listings on US exchanges, all support the thesis that informed positioning ahead of index inclusion events generates Alpha for investors who act before the announcement rather than after it.

In each case, the magnitude of the pre-event move was positively correlated with the anticipated size of the listing relative to the AUM of the relevant fund, the specificity of the fund's mandate to the listing candidate's industry, and the degree to which institutional investors lacked alternative public market proxies. All three of these conditions are satisfied to a high degree in the current case.

Key Risks to the Thesis

  • IPO delay or cancellation: The listing timeline for both the core launch Business and the satellite broadband division remains publicly unconfirmed. An extended private market Holding Period, or a decision to raise further capital privately, would defer the catalyst indefinitely.
  • GICS classification risk: An unexpected technology or communications sector classification for ITA could redirect forced buying to different funds and ETFs not covered in this report.
  • Valuation risk at listing: If the IPO prices at a significant premium to fundamental Fair Value and subsequently de-rates, ETFs with mandated inclusion will hold a declining asset. This is not a pre-IPO risk but a post-inclusion one.
  • ARK position sizing risk: ARKX's active mandate provides no guarantee that the portfolio management team will allocate at the scale assumed in the bullish scenario. A modest or delayed position would underperform the passive inclusion dynamic.
  • Thematic de-rating: Broader space economy sentiment could deteriorate in the period between current positioning and any listing announcement, reducing the inflow dynamic that supports pre-IPO ETF re-ratings.

Frequently Asked Questions

Can retail investors buy shares in the target company today?

No. The company in question remains privately held. Accredited investors may have limited access through secondary private market platforms, but these routes carry high minimum investment thresholds, limited liquidity, significant counterparty risk, and are not available to most retail participants. UFO, ARKX, and ITA represent the primary practical pathways available through standard brokerage accounts.

Which of the three ETFs has the highest probability of including the stock post-listing?

UFO has the highest mechanical probability, as its index mandate is exclusively focused on space-economy revenue and the listing candidate's revenue profile satisfies the inclusion criteria unambiguously. ITA inclusion is probable but carries GICS classification uncertainty. ARKX is not subject to index rules and therefore 'inclusion' depends on an active portfolio management decision — which, given public commentary from the investment team, we consider likely but not guaranteed.

Does the S&P 500 inclusion pathway matter for these ETFs?

It matters indirectly. If the listing company achieves the market capitalisation and profitability thresholds for S&P 500 inclusion — which at the valuation levels discussed in private market transactions would likely occur quickly — the resulting passive buying from broad-Market Index funds would provide a floor under the stock price and reduce post-listing volatility. This benefits all three ETFs' post-IPO holding experience, even though S&P 500 ETFs themselves are outside the scope of this analysis.

How should investors size a position in these ETFs given the uncertain IPO timeline?

Given the timeline uncertainty, position sizing should reflect the probability-weighted return of the catalyst materialising within the investor's holding period, adjusted for the carrying cost of the ETF's expense ratio during any delay. For investors with a two-to-three year horizon and tolerance for thematic volatility, a modest satellite position in UFO or ARKX is defensible on the space economy thesis alone, with the IPO event as an asymmetric upside case. ITA is appropriate for investors who want the exposure at lower tracking risk and are comfortable with the thesis being more diluted.
