The global nuclear energy renaissance and Small Modular Reactor (SMR) market is valued at USD 120.0 billion in 2025, anchored by primary financial data from major value-chain leaders including EDF, Constellation Energy, GE Vernova, Rolls-Royce, Cameco, and BWX Technologies.
The market is projected to reach USD 206.9 billion by 2031, representing a 1.72× expansion (72.4% absolute growth). This trajectory reflects a compound annual growth rate (CAGR) of 9.5%, making it the fastest sustained growth rate recorded across all major energy infrastructure verticals in the current forecast cycle.
The structural, 24/7 non-interruptible, and gigawatt-scale power demands of AI training and inference have established tech giants (Microsoft, Google, Amazon, Meta) as primary nuclear procurement drivers. Committed to securing over 10 GW of capacity through 2031, these hyperscalers view nuclear as the only viable, dispatchable, zero-carbon generation source capable of meeting their needs without economically prohibitive battery storage.
Remaining the dominant application by market share, this segment is valued at USD 57.6 billion (42% share) in 2025 and is forecast to grow to USD 86.9 billion by 2031 at a 7.1% CAGR, driven by steady revenue streams from the existing global reactor fleet.
Driven by decarbonization mandates in hard-to-abate sectors, this segment is growing at a 13.7% CAGR. Key catalysts include China's HTGR-PM-200 commercial precedent, X-energy’s high-temperature (935°C) Xe-100 reactor capabilities, and the integration of nuclear-derived hydrogen into the US DOE Clean Hydrogen Production Standard.
As the largest industrial segment, Construction & Engineering commands USD 42.0 billion (35% share) in 2025, growing to USD 62.1 billion by 2031 (6.7% CAGR). While it experiences a modest market share dilution to 30% due to the rapid rise of SMRs, the segment remains robustly anchored by large-scale global projects:
Asia-Pacific stands as both the largest and fastest-growing regional market, set to expand from USD 50.4 billion (42% share) in 2025 to USD 95.2 billion (46% share) by 2031 at an 11.2% CAGR. Key country-level drivers include:
The geopolitical and commercial landscape of the nuclear renaissance is defined by intense sovereign competition over technology exports. Three primary entities lead the race to secure global sovereign nuclear programs:
