According to research by the Stockholm International Peace Research Institute (SIPRI), global military spending, based on current prices, reached US$2.9 trillion in 2025.
Calculated at constant prices, global military spending in 2025 equivalent to US$2.77 trillion, representing a 2.9% year-on-year (yoy) increase compared to 2024.
This figure also marks the largest military spending record in SIPRI history. SIPRI believes this phenomenon is driven by growing insecurity in many countries.
"Rearmament and heightened insecurity fuel widespread spending increases," SIPRI stated in a press release (April 27, 2026).
"Global military spending rose again in 2025 as states responded to another year of wars, uncertainty and geopolitical upheaval with large-scale armament drives," they said.
Of the 149 countries listed in the SIPRI database, 106 countries increased military spending in 2025, while only 43 decreased.
Selected by region, the highest increase occurred in Europe, where military spending grew by 14% (yoy) in 2025.
Military spending growth in Africa reached 8.5% (yoy), Asia-Oceania grew by 8.1% (yoy), and the Middle East grew by 0.1% (yoy).
Conversely, military spending in the Americas decreased by 6.6% (yoy) in 2025. This was partly influenced by cuts in US military financial aid to Ukraine.
However, according to Nan Tian, ??Director of the SIPRI Military Expenditure Program, the US budget will increase again.
"Spending approved by the US Congress for 2026 has risen to over US$1 trillion, a substantial increase from 2025, and could rise further to US$1.5 trillion in 2027 if President Trump’s latest budget proposal is accepted," Nan Tian said in a press release (April 27, 2026).
