SpaceX and xAI combination lifts orbital AI exposure inside The Private Shares Fund (PRIVX, PIIVX, PRLVX)

SpaceX has acquired xAI in a transaction completed on February 2, 2026, and Liberty Street Advisors, Inc., adviser to The Private Shares Fund (PRIVX, PIIVX, PRLVX), has disclosed that the combined SpaceX–xAI entity now represents 18.51 percent of total fund holdings as of February 10, 2026. The portfolio shift materially increases the Fund’s exposure to the convergence of aerospace infrastructure and artificial intelligence, concentrating capital in what could become an early-stage orbital computing platform.

The announcement reframes SpaceX not only as a launch and satellite connectivity provider but as the backbone of an emerging space-based data center thesis. By integrating SpaceX’s launch cadence and Starlink’s global satellite constellation with xAI’s generative artificial intelligence models, including Grok, the combined entity moves toward a vertically integrated compute infrastructure stack that extends beyond terrestrial data centers.

Why does the SpaceX acquisition of xAI matter for orbital computing and space-based data center economics?

The strategic rationale centers on what Elon Musk has described as orbital computing, a concept that aims to relocate portions of high-intensity artificial intelligence workloads into space. The premise is straightforward but ambitious: space offers near-vacuum conditions and extreme temperature differentials that could theoretically reduce cooling costs and improve energy efficiency for compute-intensive clusters.

Data center economics on Earth are increasingly constrained by power availability, cooling infrastructure, and local grid limitations. Hyperscale operators face rising land, water, and regulatory pressures. If SpaceX can deploy modular compute units in orbit using its own launch systems, it could bypass some terrestrial bottlenecks. The integration with Starlink would then provide low-latency connectivity pathways to route data between orbital nodes and ground-based users.

The addition of xAI strengthens this thesis because artificial intelligence model training and inference are the principal drivers of next-generation compute demand. By owning both the transport layer and the AI layer, SpaceX could theoretically optimize hardware, deployment cadence, and network routing for its own artificial intelligence workloads.

However, the economics remain speculative. Launch costs, hardware resilience in radiation-heavy environments, latency constraints, and orbital debris management all introduce engineering and regulatory complexity. Orbital data centers would need to demonstrate not only technical feasibility but cost competitiveness relative to increasingly efficient terrestrial facilities powered by renewables or nuclear energy.

How does the 18.51 percent weighting in The Private Shares Fund alter concentration risk and return asymmetry?

For The Private Shares Fund, the immediate implication is portfolio concentration. At 18.51 percent of assets, the combined SpaceX–xAI position represents a high-conviction allocation. The Fund’s top ten holdings account for 49.24 percent of assets as of February 10, 2026, placing nearly half of capital in a concentrated group of late-stage private growth companies including SpaceX, GrubMarket, Nanotronics, Tradeshift, Dataminr, Motive Technologies, Databricks, EquipmentShare, Upgrade, and Betterment.

This level of concentration is not unusual for private market vehicles that target asymmetric returns. However, it does increase idiosyncratic risk. SpaceX is already one of the most valuable private aerospace companies globally, and layering xAI’s generative artificial intelligence ambitions onto that base amplifies both upside optionality and execution risk.

From a portfolio construction perspective, Liberty Street Advisors appears to be signaling confidence in the long-duration infrastructure thesis around space connectivity and artificial intelligence. Kevin Moss, Managing Director of Liberty Street Advisors and Portfolio Manager of The Private Shares Fund, indicated that the merger represents the foundation of future infrastructure. He suggested that placing artificial intelligence in orbit could overcome terrestrial power and cooling constraints and unlock unprecedented scale.

The key question for investors is whether this is an incremental evolution of SpaceX’s business model or a structural expansion into a new, capital-intensive vertical. If the orbital computing thesis materializes, the return profile could be nonlinear. If it stalls at the proof-of-concept stage, the valuation impact may depend more on SpaceX’s core launch and Starlink economics than on artificial intelligence ambitions.

What competitive and regulatory factors could determine whether orbital AI infrastructure scales or stalls?

Competition in artificial intelligence infrastructure is intensifying. Publicly traded hyperscalers are investing billions in custom silicon, data center campuses, and renewable energy procurement. Private artificial intelligence developers are securing long-term compute contracts with established cloud providers. Against that backdrop, SpaceX must prove that space-based compute can deliver differentiated performance or cost advantages.

Regulatory oversight will also play a decisive role. Expanding satellite constellations has already drawn scrutiny from international space agencies and environmental bodies concerned about orbital congestion and light pollution. Introducing compute clusters into orbit could add another layer of oversight, particularly around spectrum allocation, cross-border data governance, and cybersecurity.

Geopolitical considerations are equally relevant. Space-based infrastructure intersects with national security interests. Governments may view orbital data centers as strategic assets or potential vulnerabilities. Export controls, launch licensing, and cross-border data flows could complicate deployment.

Operationally, the integration of xAI into SpaceX raises cultural and technical alignment questions. Aerospace engineering cycles and artificial intelligence model development operate on different timelines and risk profiles. Synchronizing hardware deployment with rapidly evolving artificial intelligence architectures will require disciplined capital allocation and clear prioritization.

For The Private Shares Fund, these uncertainties translate into a long-dated option on orbital infrastructure rather than an immediate earnings catalyst. Private market valuations may not reprice daily, but eventual liquidity events or secondary transactions will reflect market sentiment around both aerospace and artificial intelligence cycles.

How does this portfolio shift position The Private Shares Fund relative to broader private market AI exposure in 2026?

Private market investors in 2026 face a different artificial intelligence landscape than in earlier hype cycles. Capital has become more selective, favoring infrastructure, foundational models, and defensible data moats over speculative application layers. By increasing effective exposure to SpaceX–xAI, The Private Shares Fund aligns itself with a capital-intensive, infrastructure-first thesis rather than a software-only narrative.

This positioning differentiates the Fund from vehicles that focus primarily on venture-stage generative artificial intelligence startups. Instead, it emphasizes a vertically integrated stack that spans launch systems, satellite connectivity, and model development. The combination creates exposure to aerospace cash flows through launch and Starlink subscriptions, alongside high-growth artificial intelligence potential.

The risk is that both businesses are capital heavy. Launch vehicles require continuous investment in research, manufacturing, and safety. Artificial intelligence model development demands sustained spending on compute and talent. If capital markets tighten or private valuations compress, funding large-scale orbital compute experiments could strain resources.

Nonetheless, the strategic coherence is clear. If artificial intelligence demand continues to outpace terrestrial infrastructure capacity, alternative compute geographies, including space, may attract serious institutional capital. In that scenario, early exposure through a concentrated private fund allocation could prove advantageous.

The Private Shares Fund’s disclosure of its top holdings reinforces its identity as a gateway to late-stage private technology leaders. With nearly half of assets in its top ten positions, performance will likely hinge on execution at a handful of companies rather than broad diversification. Investors evaluating the Fund must therefore be comfortable with concentrated bets on transformative infrastructure themes.
