XPRIZE Water Scarcity was launched to catalyze a step change in desalination. Through a five-year global competition, the prize mobilizes innovators to reimagine systems, materials, and public engagement strategies that can transform how humanity sources freshwater from seawater.

This report documents the early phases of the competition, including global participation, qualification outcomes, and the technological patterns that emerged from Qualified Teams Testing. It provides a structured analysis of system architectures, energy strategies, economic signals, and technology readiness across the advancing cohort.

The findings reveal a rapidly evolving desalination landscape defined by:

• Integrated hybrid system architectures
• Renewable-native and alternative pressure strategies
• Circular approaches to brine management
• Breakthrough materials and separation methods
• Growing commercialization readiness

Together, these developments signal a shift from incremental optimization toward systemic innovation in seawater purification.
