NATO member states finally agreed, in the recent 2025 Summit, to a serious increase in defense spending as they committed to spending 5% of their GDP by 2035. This agreement signals a significant shift in the Alliance’s posture which could reshape global arms markets, defense supply chains, and transatlantic economic relations. While the move is framed as a collective investment in shared security, the question looms large: Who will benefit from this surge in military spending?
What the 5% Commitment Means
The new pledge breaks down as 3.5% of GDP is dedicated to core military defense which includes personnel, weapons systems, ammunition, and operations. The rest 1.5% of GDP will be directed to cyber defense, infrastructure, critical resilience, and related technologies. This agreement builds on the 2% GDP minimum agreed in 2014, which many member states have not met yet. Full compliance with the 5% target is expected by 2035, with a review slated for 2029.
This development came with the pressure of the President Trump, who states afterwards that the agreement is a great victory for American workers and defense manufacturers. Why? Because a significant portion of this new spending will probably flow straight into the American defense industry.
