The $11 million XPRIZE Wildfire competition ended without either grand prize being awarded, exposing the gap between detecting a fire quickly and stopping it. One track required teams to find all fires across a large area of Australia within 10 minutes. The other required an autonomous system to locate and extinguish a high-risk fire in rural Alaska within the same period while ignoring decoys.
No space-based team satisfied every condition for the $3.5 million grand prize. SIRIUS Wildfire Alliance received $500,000 for a system combining optical and radar satellite data to detect fires and model their spread. Team Snuffed received $250,000 for an auditable approach that represented uncertainty for firefighters.
In Alaska, all three finalists detected the target in under 10 minutes, and two deployed suppression drones. None fully put out the fire. Anduril won $1.2 million after using thermal sensors, computer vision, surveillance drones and a larger drone carrying fire-retardant balls. Dryad Networks placed second with 170 solar-powered gas sensors and two drone stages.
The trials show that early alerts are becoming practical, but autonomous suppression remains constrained by payload, geography and response time. Organizers are now focusing on helping agencies test promising systems in real deployments rather than treating a competition result as proof of operational readiness.
