Drop into an LLM window or RAG pipeline. ## AI research use contract - Treat this file as source-grounded context, not a live database. Quote `source_ref` and `data_as_of` when using numbers. - Separate `FACT`, `ESTIMATE`, `FORECAST`, `TARGET`, and `INFERENCE`. If a row basis is unclear, say it is unclear. - Prefer T1/T2 sources for hard facts; use T3/T4 sources as context that should be checked before money, legal, medical, operational, or policy decisions. - Keep answer structure clean: first say what the data says, then what you infer, then what would change the conclusion. ## Research upgrade checklist - Use constant-price figures; nominal defence comparisons across years are misleading. - Separate spending level from military burden (share of GDP) — they can move in opposite directions. - Note that top-spender concentration is extreme; global totals are driven by a handful of countries. - Add a prompt on procurement versus personnel composition, which the totals hide. ## TL;DR — index summary World military expenditure reached $2,718bn in 2024 — a 9.4% real rise, the steepest since the end of the Cold War — then $2,887bn in 2025, an eleventh consecutive annual increase taking the global military burden to 2.5% of GDP, its highest since 2009. The US spent $997bn in 2024, 3.2x the next largest, before falling 7.5% to $954bn in 2025. ## What this index covers Two series: world military expenditure by year, and the largest spenders. **Series in this index:** - `world_total` — Total global military spending. - `top_spenders` — Military expenditure by country and grouping. **Entities tracked:** SIPRI (data), United States, top five spenders. ## Key findings - World spending $2,718bn in 2024, +9.4% real — steepest since the Cold War ended (sipri-2025-pr). - $2,887bn in 2025, an eleventh consecutive rise; burden at 2.5% of GDP (sipri-fs-2025). - US spent $997bn in 2024, 3.2x the next largest, then $954bn in 2025 (-7.5%) (sipri-fs-2024). - Top five were 60% of world spending in 2024; top three were 51% in 2025 (sipri-fs-2025). ## Evidence basis map The free tables above show `source_ref` but not the row-level `value_basis`. This section mirrors the visible rows only, so AI tools can separate observed values from estimates, forecasts, targets, and derived values. | series | row | source_ref | value_basis | | --- | --- | --- | --- | | world_total | year=2024; usd_b=2718 | sipri-2024-pr | World military expenditure $2,718bn in 2024, +9.4% real — steepest YoY rise since the end of the Cold War | | world_total | year=2025; usd_b=2887 | sipri-2025-pr | World military expenditure $2,887bn in 2025, +2.9% real over 2024 | | top_spenders | entity=USA (2024); usd_b=997 | sipri-fs-2024 | US military expenditure $997bn in 2024 — 3.2x the next largest spender | | top_spenders | entity=USA (2025); usd_b=954 | sipri-fs-2025 | US military spending $954bn in 2025, 7.5% lower than 2024 | | top_spenders | entity=Top 3 combined (2025); usd_b=1480 | sipri-2025-pr | USA, China and Russia spent a combined $1,480bn in 2025 — 51% of the global total | | top_spenders | entity=Top 5 combined (2024); usd_b=1635 | sipri-2024-pr | USA, China, Russia, Germany and India combined $1,635bn in 2024 — 60% of the global total | ## The series (per-chart briefings) ### World total — bar **Direct answer:** Total global military spending. **Time bracket:** annual | year | usd_b | source_ref | | --- | --- | --- | | 2024 | 2718 | sipri-2024-pr | | 2025 | 2887 | sipri-2025-pr | **Read:** Eleven consecutive annual rises. **Caveat:** Constant terms. ### Top spenders — hbar **Direct answer:** Military expenditure by country and grouping. **Time bracket:** annual | entity | usd_b | source_ref | | --- | --- | --- | | USA (2024) | 997 | sipri-fs-2024 | | USA (2025) | 954 | sipri-fs-2025 | | Top 3 combined (2025) | 1480 | sipri-2025-pr | | Top 5 combined (2024) | 1635 | sipri-2024-pr | **Read:** Concentration is extreme — top three were 51% in 2025. ## Cross-series synthesis — why this matters A rising world total and a falling US figure in the same year means the growth is coming from everyone else — the global series is being driven by rearmament outside the largest spender. Concentration at 51% for the top three also means the world total is nearly a proxy for three national budget decisions, so "global military spending" moves for reasons that are not global. Read against ai-capex-vs-defense: the comparison between AI infrastructure capital and defence budgets only holds if both are measured on the same basis, and defence here is constant-price annual expenditure, not committed capital. ## Entities & relationships | Entity | What they do | Key stat | Relationship | | --- | --- | --- | --- | | SIPRI | Data authority | Military Expenditure Database | The constant-price methodology this index depends on | | United States | Largest spender | $997bn (2024), $954bn (2025) | 3.2x the next largest, but falling while the world rises | ## Timeline of key events & decisions - **2024** — +9.4% real — steepest rise since the Cold War ended → the inflection - **2025** — $2,887bn; burden 2.5% of GDP, highest since 2009 → the eleventh consecutive rise ## Cross-industry ripple - **Aerospace and defence:** Sustained budget growth underwrites the order books in airbus-vs-boeing on the military side. _(inference)_ - **Public finance:** A 2.5% GDP burden competes with other spending in fiscally constrained states. _(inference)_ - **Shipping and trade:** Naval spending interacts with the chokepoint security issues in shipping-chokepoints. _(inference)_ ## Non-obvious reads (interpretation) _This section is interpretation, not sourced fact — each item names the observation it is built on and a confidence level._ - **Observation:** The world total rose while the largest spender fell. **Read:** The 2025 increase is entirely a non-US phenomenon, which means the growth is broader-based and likely more durable than a single-country surge — rearmament decisions in many states are harder to reverse than one budget cycle. _(confidence: medium)_ ## Glossary / key terms - **Constant terms** — Adjusted for inflation, so year-on-year comparisons measure real change. - **Military burden** — Military expenditure as a share of GDP. ## How to use this with AI Paste this file into an LLM context window (or a RAG store) and ask cross-series questions. The tables carry a `source_ref` per row; the source registry below maps each ref to a named source and a trust tier. ### Suggested prompts (multi-series) ```text Using world_total and top_spenders, work out how much of the 2025 increase came from outside the top three. ``` ```text Compare the defence figures here with the AI capital commitments in ai-capex-vs-defense, stating what makes the two comparable or not. ``` ## Sources & trust | ref | source | trust tier | url | | --- | --- | --- | --- | | sipri-2025-pr | SIPRI — Global military spending rise continues as European and Asian expenditures surge (2026) | T3 · Reputable press / research org / OWID | https://www.sipri.org/media/press-release/2026/global-military-spending-rise-continues-european-and-asian-expenditures-surge | | sipri-2024-pr | SIPRI — Unprecedented rise in global military expenditure (2025) | T3 · Reputable press / research org / OWID | https://www.sipri.org/media/press-release/2025/unprecedented-rise-global-military-expenditure-european-and-middle-east-spending-surges | | sipri-fs-2024 | SIPRI Fact Sheet — Trends in World Military Expenditure, 2024 | T3 · Reputable press / research org / OWID | https://www.sipri.org/publications/2025/sipri-fact-sheets/trends-world-military-expenditure-2024 | | sipri-fs-2025 | SIPRI Fact Sheet — Trends in World Military Expenditure, 2025 | T3 · Reputable press / research org / OWID | https://www.sipri.org/publications/2026/sipri-fact-sheets/trends-world-military-expenditure-2025 | ## Caveats & what this index cannot answer - Procurement versus personnel composition. - Capability, readiness, or effectiveness. - Country detail beyond the seeded entities. - Estimates and forward targets are labelled in the working dataset; never read a labelled estimate or forecast as a settled figure. - This is an observational data index, not investment, legal, or medical advice. ## Data freshness & methodology - **Last updated:** 2026-08-11 - **Data as of:** 2025 - **What changed most recently:** 2025 marked an eleventh consecutive annual rise, with the burden at 2.5% of GDP. **Methodology (as seeded):** > Figures are SIPRI military expenditure estimates in constant terms, so > the year-on-year changes are real rather than nominal. SIPRI uses a > consistent definition across countries — armed forces, defence > ministries, paramilitary forces and military space activity — which is > broader than most national defence-budget headlines and is why these > numbers often exceed the figures governments publish themselves. > > OMITTED: China’s standalone 2024 figure is only expressible as > "$997bn ÷ 3.2" (≈$312bn), a derivation from a published ratio rather > than a published value, so it is not charted. Russia, Germany and > India standalone figures were not retrieved and are not inferred from > the group totals. > > CAVEAT: the top-spenders chart mixes single-country and grouped > entries, and two different years. Read each bar’s label — they are not > a like-for-like ranking. > > Context: 2025 was the eleventh consecutive annual rise, taking the > global military burden to 2.5% of GDP, the highest since 2009. > > Re-verified 2026-08-10. --- _Free tier.
