Liquidity

Liquidity is the make-or-break factor for player-versus-player products. A poker site with deep liquidity offers more tables, larger tournaments, and faster game starts; a thin poker site offers limited options and slow game starts. The dynamic creates strong network effects: large poker networks attract more players, which attracts more players. The result is significant concentration in poker, with PokerStars (now part of Flutter) and a small number of competitors holding outsized share globally. The same dynamics apply to betting exchanges (Betfair being the dominant example), peer-to-peer skill gaming, and DFS contests. Cross-border liquidity sharing has been a major regulatory issue for poker in particular: regulated markets that pool liquidity (the Southern European poker network combining France, Italy, Spain, and Portugal) offer better product quality than single-market liquidity, but regulatory frameworks vary on whether pooling is permitted. The historical drift toward isolated national poker markets has been one of the headwinds for poker GGR in Europe.
