XPRIZE Wildfire Drones Detect Blazes in 10 Minutes but Fail to Extinguish Them
XPRIZE Wildfire awarded satellite and drone teams, but neither track claimed its grand prize after suppression systems failed to extinguish Alaska's blaze.
Summary
The $11 million XPRIZE Wildfire ended September 23, 2026, without awarding either grand prize. One track required every fire in an Australian zone detected within 10 minutes; another required autonomous detection and extinguishing of a high-risk fire among decoys in rural Alaska within 10 minutes. It drew 45 qualified space entries and over 300 response teams; 911 discovery averages at least 15 minutes.
At New South Wales Rural Fire Service tests in April 2026, no team won Minderoo Foundation's $3.5 million prize. SIRIUS Wildfire Alliance won $500,000 for optical and radar satellite detection and spread modeling; Team Snuffed, $250,000 for auditable, uncertainty-aware tools; MyRadar, DeepFire and Mayday.AI, $100,000 each, with Mayday.AI adapting volcanic-ash algorithms to detect smoke through clouds. OroraTech launched dedicated fire satellites in March 2025; Google-backed FireSat launched its first microsatellites in July 2026.
At June 2026 tests near Nenana, all three finalists detected fire across 386 square miles within 10 minutes; two deployed drones, but none extinguished it. Anduril Industries won $1.2 million and Lockheed Martin's $1 million fastest-detection prize with an AI thermal Sentry Tower, surveillance swarm and retardant-dropping Ghost-X. Dryad Networks won $800,000 using 170 solar gas sensors, an observation drone and Silvaguard Suppression Drone; AURA Foresight won $500,000 with AI, off-the-shelf gear and DJI drones assembled within weeks by UK-Australian teams meeting first in Alaska. Since the April 2023 launch, fires killed at least 102 in Lahaina, caused $140 billion in Los Angeles losses, and forced over 320,000 evacuations in Spain and France. Organizers will support deployments and consider a follow-up.
Positives
- All three autonomous-response finalists detected the target fire across 386 square miles in under 10 minutes.
- SIRIUS Wildfire Alliance won $500,000 for combining optical and radar satellite data with fire-spread modeling.
- Anduril Industries secured $2.2 million using Sentry Tower, a surveillance swarm and the Ghost-X suppression drone.
- Dryad Networks coordinated 170 solar gas sensors, an observation drone and the Silvaguard Suppression Drone.
- OroraTech and Google-backed FireSat launched dedicated wildfire satellites in March 2025 and July 2026, respectively.
Risks & concerns
- Neither XPRIZE Wildfire track awarded its grand prize because no finalist met every detection and suppression requirement.
- None of the three Alaska finalists fully extinguished the target fire, despite all detecting it within 10 minutes.
- Typical wildfire discovery through a 911 call still takes at least 15 minutes, allowing fires more time to spread.
- Los Angeles' January 2025 fires destroyed almost 12,000 homes, killed 31 people and caused an estimated $140 billion in losses.
- Wildfires forced more than 320,000 evacuations in Spain and France during 2026 and threatened NASA infrastructure near Madrid.
