## Market Share Squared

Market Share Squared is the mathematical core of the Herfindahl-Hirschman Index, where the percentage of market share for each entity is multiplied by itself. This process gives disproportionate weight to larger firms, effectively highlighting the impact of dominant players on the overall market structure.

In the context of digital assets, this calculation is used to emphasize the influence of major exchanges on total trading volume. By squaring the shares, the metric captures the exponential increase in market power that occurs as one entity gains more dominance.

It is a precise way to differentiate between a market with many medium-sized players and a market with one or two massive entities. This approach is standard in regulatory and economic analysis to assess the health of competitive environments.

It serves as a diagnostic tool for identifying markets that are structurally biased toward centralization.
