What the 2026 NATO Ankara Summit Means for European Defence Investment

The 2026 NATO Summit in Ankara took place one year after Allied leaders agreed a major change in defence investment policy at the 2025 Summit in The Hague. Under that commitment, Allies aim to invest 5% of GDP annually in defence and security-related expenditure by 2035. At least 3.5% is intended for core defence requirements, while up to 1.5% can cover areas including critical infrastructure, network protection, civil preparedness, resilience, innovation and the defence industrial base.

Ankara therefore did not establish a new spending target. Its significance was in showing how the Alliance intends to translate that commitment into capabilities and industrial output. Ahead of the Summit, NATO Secretary General Mark Rutte said that European Allies and Canada were already investing around 4% of GDP in defence and security. NATO also reported that European Allies and Canada had increased investment in core defence requirements by more than US$139 billion in nominal terms in 2025.

The Summit added a more concrete demand signal. Allied leaders announced more than US$50 billion in new procurements and committed to expanding collective manufacturing capacity, accelerating innovation and reducing defence trade barriers among Allies. NATO also highlighted requirements across integrated air and missile defence, deep precision strike, uncrewed systems, advanced technologies and intelligence capabilities.

For investors, headline defence budgets provide only part of the picture. The more relevant question is where higher public expenditure is actually being converted into procurement programmes, production requirements and multi-year demand that companies can address.

Rising defence budgets do not automatically translate into additional military capability. The pace of delivery increasingly depends on whether European industry can add production capacity, secure critical components, recruit skilled workers and strengthen supply chains quickly enough to meet new orders. For investors, these constraints can help determine where additional spending is likely to create sustained demand and where industrial bottlenecks may limit growth.

The Ankara Summit placed industrial scale directly within NATO’s implementation agenda. NATO launched an Innovation Scale-Up Package built around three areas: signalling Allied demand, mobilising private capital and facilitating manufacturing. The Alliance also introduced the NATO Engine, designed to connect companies that need additional manufacturing capacity with factories able to provide it, alongside the NATO Front Door for Industry, intended to simplify access to procurement opportunities and other forms of engagement with NATO.

This widens the investment lens beyond large defence primes. Growing production requirements can affect companies across components, electronics, advanced materials, autonomous systems, software, cyber security, logistics, industrial machinery and other enabling technologies. The additional 1.5% component of NATO’s 5% commitment also extends the relevant investment universe into areas such as critical infrastructure, network resilience, civil preparedness, innovation and the defence industrial base.

At the same time, higher aggregate spending does not mean that every company exposed to defence will benefit equally. Investors still need to understand where capability demand is concentrated, how procurement works in individual markets, whether a company can meet defence standards and production requirements, and whether public commitments are translating into contracts relevant to its products.

One of the clearest investment signals from Ankara was NATO’s effort to increase the role of private finance.

At the NATO Summit Defence Industry Forum on 7 July, the Alliance launched a Call to Action encouraging financial institutions to increase lending and equity investment across defence, security and resilience. The initiative was welcomed by institutions including Banco Santander, Barclays, BNP Paribas, Citi, Deutsche Bank, NatWest, PKO Bank Polski, Danske Bank, the Business Development Bank of Canada and the NATO Innovation Fund. NATO reported that these institutions had collectively already mobilised US$217 billion for defence and security.

The Innovation Scale-Up Package goes further by calling on private capital providers to increase allocations to companies developing and manufacturing technologies for Allied defence, support additional manufacturing capacity and facilitate cross-border investment. It also identifies a role for governments in providing clearer demand signals, supporting joint procurement, using public financial institutions to reduce investment constraints and developing public-private co-investment models.

This does not remove the characteristics that have historically made defence difficult for some private investors. Procurement cycles can be long, demand remains closely connected to governments, export restrictions and security requirements can affect market access, and political decisions can materially change programme timing. Ankara nevertheless showed that NATO now expects private capital to play a more direct role in expanding defence production. The Alliance is explicitly linking access to finance with the ability of smaller and non-traditional suppliers to move from product development into larger-scale manufacturing.

A second development reinforced this direction. Separately from NATO’s formal structures, the leaders of Canada, Albania, Belgium, Greece, Latvia, Luxembourg, Romania, Türkiye and Ukraine announced in Ankara their intention to establish the Defence, Security and Resilience Bank (DSRB). The proposed multilateral institution is designed to mobilise public and private capital, reduce financing costs and support industrial capacity, with operations targeted to begin as early as 2027.

The DSRB remains an emerging initiative rather than an Alliance-wide financing mechanism, and several major NATO economies were not among the initial participating countries. Its relevance for investors lies less in its current scale than in the type of financing problem it is intended to address: governments are looking for additional structures capable of connecting strategic defence requirements with larger pools of long-term capital.

The implications of this shift extend beyond weapons manufacturing. NATO’s spending framework explicitly includes expenditure related to infrastructure, resilience, networks, innovation and the defence industrial base, while the Ankara industrial agenda placed greater emphasis on the capacity to produce and sustain military capabilities at scale. That creates potential investment relevance across defence and dual-use technologies, advanced manufacturing, logistics, cyber security, communications, energy resilience and critical infrastructure.

The broader security environment reinforces this emphasis on resilience. The Ankara Declaration identifies Russia as a long-term threat to Euro-Atlantic security and refers to strategic competition, persistent instability, hybrid threats and recurrent shocks as features of the wider security environment. Allies also reaffirmed long-term support for Ukraine and pledged €70 billion in military equipment, assistance and training for 2026.

For investors, this makes geographic exposure, supply-chain dependence, production location and access to trusted markets increasingly relevant to company assessment. Defence businesses may benefit from stronger demand while simultaneously facing restrictions around ownership, exports, technology transfer and procurement eligibility. Companies operating across several jurisdictions can also encounter different national procurement systems and industrial policies despite the broader NATO framework.

The result is an investment environment in which public spending provides an important demand signal, but the commercial opportunity still depends on how individual companies are positioned within procurement systems, industrial supply chains and national regulatory frameworks.

The Ankara Summit strengthened the evidence that Europe’s defence build-up is developing into a long-term industrial and capital-allocation theme. The 5% commitment provides a policy framework extending to 2035, while Ankara added substantial procurement announcements, new measures aimed at expanding industrial capacity and a stronger emphasis on private financing. For investors, however, these developments still need to be assessed at the level of individual markets, technologies and companies rather than treated as a uniform sector-wide growth story.

Several factors deserve particular attention for investors. Announced defence budgets become commercially relevant when they are converted into funded programmes and contracts that companies can actually address. Higher demand also creates value only where businesses are able to expand production at the required pace and quality. Opportunities are not limited to large prime contractors: specialised suppliers, component manufacturers and technologies that help remove production bottlenecks can also benefit from the build-up. At the same time, procurement rules, security requirements, foreign investment screening, export controls and national industrial preferences can affect market access even when underlying demand is strong. NATO’s new demand signals, industrial initiatives and procurement announcements are intended in part to improve the connection between capability requirements and industrial delivery.

The growing role of private capital introduces another set of questions. Investors need to assess which financing mechanisms can genuinely improve companies’ access to capital, which businesses can scale without becoming dependent on one procurement programme, and whether stronger links between government demand and private financing can support sustainable commercial models. NATO’s Call to Action and Innovation Scale-Up Package indicate that these financing questions are now being addressed directly within the Alliance’s defence-industrial agenda.

Key developments to watch after Ankara include the implementation of the more than US$50 billion in announced procurements, national pathways towards the 5% spending commitment, the implementation of the Innovation Scale-Up Package and NATO Engine, further development of financing mechanisms such as the DSRB, and the extent to which additional capital reaches smaller suppliers and defence technology companies alongside established contractors.

Ankara reinforced a broader shift already under way in European defence. Governments are committing more capital, but the investment opportunity will ultimately depend on which companies can convert that demand into contracts, production and repeatable growth. For investors, the useful question is therefore not simply how much Europe will spend on defence, but where that spending is likely to create durable commercial demand.
