Below is a completely random collection of market share estimates. I was curious to what’s more interesting; the gap between the #1 & #2 players or the degree to which the overall market is consolidated?

Would you rather invest in a company that operates in a near duopoly or a company that has significantly more market share than their top competitor?

Please comment with any interesting market share dynamics you’re aware of. I think the next step of this analysis would be to compare EBITDA margins among the different cohorts of market concentration. Ideally I would also be able to attach a timeline on how long this relationship has been in place; is this a recent consolidation or have the #1 & #2 players been battling for years?
