The data comes from the Stockholm International Peace Research Institute, which publishes an annual report tracking military expenditure worldwide. The headline finding: the United States, China and Russia together accounted for $1,480 billion, 51% of the global total.
The US dip and what comes next
Despite topping the global rankings, American military spending actually fell in 2025. At $954 billion, the figure was down 7.5% from 2024, largely because no new financial military assistance for Ukraine was approved during the year, unlike the previous three years, when a combined $127 billion was cleared.
That said, the US continued investing in nuclear and conventional capabilities to maintain dominance in the Western Hemisphere and deter China in the Indo-Pacific, both identified as priorities in the country's new National Security Strategy. SIPRI noted that 2026 data is expected to show a steep reversal, driven by the costs of the US-Iran war.
Europe: The sharpest surge since the Cold War
Europe was the biggest driver of the global increase. Regional expenditure climbed 14% to $864 billion, with NATO members' rearmament driving the sharpest annual growth in Central and Western Europe since the end of the Cold War.
Russia's spending rose 5.9% to $190 billion, representing a military burden of 7.5% of GDP. Ukraine, now the world's seventh largest military spender, raised its outlay by 20% to $84.1 billion, equivalent to 40% of GDP. The 29 European NATO members collectively spent $559 billion, with 22 of them allocating at least 2% of GDP to defence.
Germany led the group with spending up 24% year-on-year to $114 billion, crossing the 2% GDP threshold for the first time since 1990 and reaching 2.3% in 2025. Spain's military budget rose 50% to $40.2 billion, taking its military burden above 2% of GDP for the first time since 1994.
Asia and Oceania: Largest increase since 2009
Military expenditure across Asia and Oceania totalled $681 billion in 2025, up 8.1%, the region's largest annual jump since 2009. China, the world's second-largest military spender, increased its outlay by 7.4% to $336 billion, marking its 31st consecutive year-on-year rise as its military modernisation programme continued uninterrupted. SIPRI noted that a renewed anti-corruption campaign in military procurement did not appear to constrain spending.
Japan's military expenditure rose 9.7% to $62.2 billion, equal to 1.4% of GDP and the highest share since 1958. Taiwan increased spending by 14% to $18.2 billion, or 2.1% of GDP, its largest annual rise since at least 1988, as the People's Liberation Army intensified military exercises around the island.
Pakistan's military spending rose 11% to $11.9 billion, widening the gap with India, which outspends its neighbour by more than seven to one.
The Middle East: Mostly up, Israel down
Military expenditure across the Middle East was estimated at $218 billion in 2025, marginally above 2024 levels. Israel's spending fell 4.9% to $48.3 billion, reflecting lower intensity in the Gaza conflict following the January 2025 ceasefire with Hamas, though its outlay remains 97% higher than in 2022.
Turkey's military budget rose 7.2% to $30 billion, driven in part by operations in Iraq, Somalia and Syria. Iran's spending fell for the second consecutive year, down 5.6% in real terms to $7.4 billion, a decline SIPRI attributed to annual inflation of 42%, even as nominal spending rose.
