The Two-Headed Dragon: Investing in the AI Infrastructure Arms Race and the New Private Markets
The single, dominant global investment thesis in 2025 is a dual-focus strategy driven by two profoundly interconnected forces: the transformative, infrastructure-intensive rise of Generative Artificial Intelligence (GenAI), and the continuous structural shift of capital into Private Markets.
The world's most sophisticated investors—from family offices to sovereign funds—are rapidly deploying capital into assets that both power the AI revolution and provide a crucial buffer against global volatility. The result is a fundamental rewriting of asset allocation, where high-growth, high-profit opportunities now largely reside in illiquid, private asset classes.
Pillar 1: The AI Infrastructure Arms Race
GenAI has shifted from a technological concept to a capital-intensive utility, creating an unprecedented global arms race focused on the foundational, physical assets that underpin its function. This focus on infrastructure spending is where the most significant capital flows are concentrated.
The Compute and Power Bottleneck
The demand for processing power from GenAI and large language models has triggered a trillion-dollar surge in data centre construction and accelerated computing globally. Major global technology firms are collectively committing hundreds of billions of dollars towards building AI-enabled data centres. Projects like the massive Stargate Initiative, a $500 billion private-sector plan to build the world's largest AI infrastructure network, underscore the scale of this capital deployment.
Venture Capital Dominance: The AI sector now commands an extraordinary share of global risk capital. In the first half of 2025, AI startups captured 53% of all global VC funding (Source: EY, H1 2025 data), with average deal sizes for late-stage companies more than tripling. The focus has decisively shifted from funding abstract innovation to funding startups that can demonstrate enterprise adoption and profitability by integrating AI into existing workflows (e.g., in fintech, healthcare, and manufacturing).
The Private Equity Play: Private Equity (PE) firms are largely avoiding the riskiest startup bets, instead deploying capital into tangible data infrastructure investments—a less volatile way to capitalise on the AI boom. PE deal value involving data centre targets more than doubled in 2024 and is on track for another strong year in 2025.
Pillar 2: The Structural Shift to Private Capital
While tech remains the largest growth engine, the private asset classes that fund and house this growth offer portfolio protection and income stability. This structural shift is cementing private markets as a permanent feature of sophisticated global investment strategies.
Growth in Private Credit and Real Assets
Private Credit Dominance: Private credit (non-bank corporate lending) is a fast-growing pillar of global portfolios, with projections suggesting it could hit $2.8 trillion by 2028. Its appeal is simple: it offers strong, floating-rate yields that are less correlated with public markets. However, this growth is not without risk; investors must be mindful of potential systemic risks, such as tighter financial conditions putting pressure on weaker borrowers, and the looming maturity wall of high-yield bonds and leveraged loans set to come due in 2026–2027, which will test the market's credit quality.
Targeted Real Estate & Infrastructure: Investors are heavily allocating to real assets that support secular themes. This includes digital infrastructure, energy transition assets (to feed the power-hungry data centres), and logistics. Private infrastructure remains a critical shelter against persistent inflation and public equity volatility globally.
Balancing the Bullish Outlook with Risk
While the opportunity is immense, investors should maintain a nuanced view. The primary challenge facing the AI infrastructure build-out is capacity constraints. Data centre vacancy rates in primary markets are at record lows, and scaling AI requires solving real-world challenges around power grids, supply chains, and specialised talent. The financial appetite for AI may create isolated volatility, especially if a large, leveraged private deal falters due to the highly specific nature of its financing or infrastructure execution.
The most successful wealth management strategies blend this bullish, theme-driven growth with cautious risk management, using private credit for income and real assets for stability.
The investment thesis is clear: the AI revolution is largely a private capital story. The world's capital is not merely betting on AI models; it is financing the massive physical and financial architecture required to run them.
