Defence stocks have emerged as clear beneficiaries in the current geopolitical landscape; however, the broader investment narrative is beginning to extend beyond just weapons manufacturers. Increased military expenditures are being allocated toward drones, cybersecurity, aerospace, and surveillance. Concurrently, the prevailing geopolitical pressures are compelling governments to enhance their investments in energy security, electricity grids, data centers, and critical infrastructure.

Global military expenditure reached $2.89 trillion in 2025, reflecting a 2.9% increase in real terms and marking the 11th consecutive annual rise, according to figures cited by Vijay Valecha. Expenditure beyond the United States increased by 9.2%, whereas military spending in Europe surged by 14%, reaching a total of $864 billion.
