Herfindahl-Hirschman Index

The Herfindahl-Hirschman Index is a standard measure of market concentration calculated by squaring the market share of each firm competing in a market and then summing the resulting numbers. In crypto derivatives, it helps quantify the competitive landscape of exchanges or asset dominance.

A result closer to zero indicates a highly competitive market with many small participants, while a result closer to ten thousand indicates a monopoly or extreme concentration. Regulators and analysts use this index to determine if an exchange ecosystem is becoming too centralized.

It provides a clear numerical threshold to evaluate the potential for anti-competitive behavior. By tracking changes in this index, one can observe shifts in market power as new protocols gain traction or established ones lose dominance.

This metric is fundamental for risk management when assessing counterparty risk across different platforms.
