Global data centre investment surges $235bn, outpacing oil, renewables and property — UNCTAD

Why $235bn flooded into data centre construction while renewables slid $37bn

Foreign direct investment flows are being rewritten by the digital economy. According to the UN Conference on Trade and Development's World Investment Report 2026, announced greenfield projects and international project finance deals show that data centres have become the new heavyweight of global capital. Between 2024 and 2025, investment commitments into data centre construction rose by roughly $235 billion — a figure that dwarfs gains in every other major sector tracked by the report.

The oil and gas industry, still a cornerstone of energy investment, added $38 billion in new FDI over the same period, while the semiconductor sector — often portrayed as the front line of the technology arms race — attracted just $13 billion of fresh investment. These numbers are not small in absolute terms, but they look modest next to the data centre boom, underscoring how infrastructure for artificial intelligence and cloud computing is now competing directly with traditional heavy industries for capital.

The momentum in data centres stands in sharp contrast to the reversals seen elsewhere. Industries tied to global value chains and general infrastructure each contracted by $55 billion in new FDI announcements. Renewable energy investment, which had been on a long upward trajectory, fell by $37 billion — an outcome the report's authors described as curious, given the parallel surge in power-hungry digital infrastructure. Real estate lost $31 billion, and critical minerals, essential for the energy transition, slipped by $5 billion.

The report paints a picture of an investment landscape in transition: capital is concentrating in the physical backbone of the AI era, while sectors that might be expected to benefit from that expansion — particularly clean energy and the raw materials that feed technology supply chains — are seeing investors step back.

What the UNCTAD investment shift means for tech, energy and real assets

The AI-fuelled data centre land grab

The $235 billion jump is not an accident. It reflects the scramble to build the server farms that train large language models, power cloud services and process the data torrent generated by connected devices. Hyperscale operators are competing for land, grid connections and construction capacity at a pace that has no modern parallel. The UNCTAD figures confirm that this is now the single largest theme in global capital expenditure — and it is still accelerating.

A critical detail in the numbers is that the surge in data centre investment has not, so far, pulled renewables along with it. On the contrary, green energy FDI contracted by $37 billion. That disconnect suggests developers are securing power where it is available — often from existing fossil fuel grids — rather than waiting for new solar or wind farms to come online. It may also indicate that the sheer urgency of data centre delivery is overriding clean energy commitments in the short term.

Why oil and gas still attract capital

Oil and gas added a respectable $38 billion, confirming that the fossil fuel sector has not been abandoned by international investors. The figure may partly reflect the energy security concerns that have driven new liquefied natural gas terminals and upstream projects. For data centre developers, the continued flow of money into hydrocarbons is significant: it means there is still a plentiful — and often politically expedient — source of baseload power for new digital infrastructure, at least where renewable capacity is lagging.

Semiconductors: a slower investment cycle

The $13 billion increase in semiconductor FDI is far from trivial, but it underscores a different rhythm. Chip fabs require years to plan and build, and much of the recent government-backed capacity expansion (through the US CHIPS Act and EU Chips Act) was already accounted for in earlier years. The UNCTAD data suggest that the next wave of chip investment has yet to be reflected in international project finance, potentially creating a mismatch between data centre demand and the supply of advanced processors.

Winners and losers in the new FDI order

The $55 billion drop in value chain and general infrastructure investment points to a hard choice: capital that might once have funded ports, roads or industrial parks is now being redirected to server halls. That reallocation carries consequences for emerging economies that depend on traditional infrastructure FDI for growth. The simultaneous retreat from renewables and real estate adds to the picture of an investment climate that is concentrating risk as well as opportunity.

It is important to note that these are announced project values, not completed spending. Some projects may be delayed or cancelled. However, the size and direction of the shift are so pronounced that the trend is unmistakable. The digital backbone is now the global economy's primary investment magnet, and sectors that cannot demonstrate a direct link to that demand story are struggling to attract fresh capital.

Strategic imperatives for data centre operators, energy planners and governments

For data centre developers and hyperscale operators:

• The 23% contraction in renewable energy FDI means power purchase agreements (PPAs) tied to new solar and wind capacity are likely to become scarcer and more expensive in the near term. Secure long-term electricity contracts now, including hybrid deals that blend fossil-fuel baseload with renewable certificates, to lock in costs before grid constraints intensify.
• The $38 billion still flowing into oil and gas signals that natural gas-fired backup and peaking plants will remain a pragmatic bridge. Plan site selection around existing gas infrastructure and pipeline capacity, not just fibre.
• With value chain and general infrastructure investment down $55 billion, the supply of construction materials, heavy equipment and skilled labour for large-scale builds could tighten. Pre-committing to suppliers and developing modular construction approaches will be critical to avoid project delays.

For renewable energy companies and investors:

• The $37 billion drop in announced renewables FDI is a warning that project finance is not automatically flowing to the sector, even as power demand from data centres explodes. To reverse the trend, developers must position their projects as essential infrastructure for the digital economy, not just climate assets — for example, by co-locating solar farms directly with data centre campuses or offering 24/7 clean power solutions through battery storage.
• Governments and development finance institutions should note that the critical minerals segment lost $5 billion; this threatens the supply chain of metals needed for batteries and turbines. De-risking mining and processing projects in stable jurisdictions could unlock capital that is currently sitting on the sidelines.

For governments and economic development agencies:

• The data centre boom is a double-edged sword. Attracting server farms without a parallel plan for power generation and grid upgrades can lead to electricity price spikes and political backlash. Use the UNCTAD data to justify fast-tracked permitting for renewable and gas generation that is explicitly tied to data centre demand, creating a visible pipeline for investors.
• The $55 billion contraction in general infrastructure FDI means traditional public-private partnerships may struggle to compete with digital projects for international capital. Consider blending data centre investment requirements with local infrastructure upgrades — for example, requiring developers to contribute to grid reinforcement or road access as a condition of site approval.
• Semiconductor FDI expanded by only $13 billion, even as AI compute demand soars. Industrial policy aimed at chip self-sufficiency should be calibrated against this modest investment appetite; overly ambitious fab projects risk under-delivery if private capital remains focused on the faster-returning data centre segment.
