Market liquidity functions as a public good — but it is being provided by a private monopolist whose interests do not align with retail investors.
Liquidity in public markets reduces transaction costs for everyone, enables price discovery, and facilitates efficient capital allocation. These are public benefits. When a single private firm captures 40% of retail order flow, the concentration creates accountability obligations that go beyond maximizing Griffin personal wealth.
