Cohort comparison at a glance
Every figure below comes from the official DIANA announcement for that round. Selection rates are approximate upper bounds because NATO publishes several applicant totals as rounded minimums.
| Round | Announced | Companies | Countries | Applicants | Selection rate |
|---|---|---|---|---|---|
| 2024 | November 2023 | 44 | 19 | 1,300+ | ~3.4% |
| 2025 | December 2024 | 72 | 20 | 2,600+ | ~2.8% |
| 2026 | December 2025 | 150 | 24 | 3,600+ | ~4.2% |
| Warfighters | July 2026 | 10 | 6 | 427 | ~2.3% |
| 2027 | Not publicly available | ||||

Methodology and limitations
Cohort totals are taken from the DIANA announcement for each round. Company records are tracked individually only where a company is publicly identifiable, so tracked records can be lower than the announced total for a round.
Applicant counts published as rounded minimums are shown exactly as NATO states them, and derived selection rates are therefore upper bounds.
Alliance Tech Tracker is independent and unofficial and is not affiliated with or endorsed by NATO or DIANA. Where a value is not published, records show "Not publicly available" rather than an estimate. See the full methodology.
