GENEVA, June 8 - Spending on nuclear weapons among the nine states that possess nuclear arms rose sharply in 2025, reaching a total of $119 billion, according to a report published by the International Campaign to Abolish Nuclear Weapons (ICAN).
The increase of 19% from 2024 marks the highest level of spending recorded by ICAN since it began tracking annual nuclear arms expenditure in 2020. The campaign group said the aggregated figure covers the expenditures of the United States, Russia, China, France, Britain, India, Pakistan, North Korea and Israel.
ICAN's breakdown shows that the United States remained by far the largest single spender on nuclear arms, allocating $69.2 billion in 2025 - more than the combined totals of the other eight nuclear-armed states. That represented the largest year-on-year rise among the countries tracked, a 22% increase.
The report noted that the U.S. increase forms part of a broader uptick in military spending alongside programs to rebuild elements of its nuclear arsenal.
China was the second-largest spender, with expenditure rising 7% to $13.5 billion. Britain moved ahead of Russia to become the third-largest national spender on nuclear arms, increasing its outlays by 17% to $12.6 billion. Russia's nuclear spending also rose, by 6%, to $9.5 billion.
ICAN, the 2017 Nobel Peace Prize laureate, advocates for the complete elimination of nuclear weapons. The group's reporting on annual nuclear arms expenditure is intended to track trends in national investments in nuclear capabilities.

ICAN's dataset covers the nine states known to possess nuclear weapons and is aimed at revealing spending trends rather than providing policy recommendations. The report's figures highlight an upward trajectory in allocated funds for nuclear capabilities in 2025 compared with the prior year.
Observers of defense budgets and markets may use this data to assess how government resource allocations are shifting within national defence priorities, particularly in relation to nuclear modernization and broader military spending increases.
