Will a US ally get a nuke before 2027?

Prediction markets put the probability at 6%: Will a US ally get a nuke before 2027. Currently, markets see this as unlikely (6% YES). More worrying for European allies has been the evident indifference of the United States to the consequences of its actions.

What’s Happening

The question of whether a US ally get a nuke before 2027 has moved from theoretical to actively debated as Washington signals a reduced commitment to European security. US Secretary of Defense Pete Hegseth told European partners to be ready by 2027 to defend themselves without American help, a shift that European capitals have read as an existential prompt given a nuclear-armed Russia that invaded Ukraine. Analysts note the immediate threat perceived in Europe stems less from a weakened Iran than from Moscow's demonstrated willingness toward cross-border aggression, sharpening debate over independent deterrence.

France remains central to any near-term scenario in which a us ally get a nuke capability expands on the continent. President Emmanuel Macron visited a French nuclear submarine base in February 2026 and is weighing revisions to France's deterrence doctrine before elections choose his successor in 2027. Any extension of the French umbrella would not create a new arsenal but could reshape how existing warheads are shared. The United Kingdom's deterrent, by contrast, remains tethered to Washington via its Trident dependency, limiting how quickly a fully autonomous European posture could emerge absent a major policy shift.

Structurally, the odds that a us ally get a nuke outright before 2027 remain constrained by timelines and treaty commitments. Modernization of US gravity bombs across six European bases in Germany, Belgium, Italy, the Netherlands and Turkey was completed in early 2025, and additional warheads may have been deployed to the UK as it rejoins NATO nuclear sharing. Australia's path to hosting US nuclear operations is projected for the early 2030s, well beyond the window. Near-term developments point toward sharing arrangements and forward deterrence rather than any ally fielding an independent weapon before the deadline. [ETH Zurich CSS, Jul 25]
