• China is the world's top producer of indium, making up 70% of global output as of 2024.
• Since China introduced export restrictions on InP, the average price for a 6-inch InP wafer has surged 250% to $5,000.
• InP is in high demand as it is a core material with no substitute in the new technology that data centre developers are turning to - using light through optical fibres, or photonics.
