The study sample included 95% of banks in the GCC banks market from UAE, kingdom of Bahrain, Kuwait and KSA through 6 years.

Market power hypothesis included structure-conduct-performance hypothesis and traditional efficiency hypothesis .these hypotheses were tested using linear regression as return on assets (ROA) were tested as an indicator of profitability and it also tested concentration and market share.

The results showed that in some countries, Islamic banks are concentrated whereas the advanced analysis of the relation between concentration and performance showed that traditional banks are the ones who benefit from its concentration in achieving high returns.
