The rapid growth of Islamic banking in Indonesia has intensified competition between incumbent and digital Islamic banks. However, studies examining their strategic interactions remain limited. This study analyzes the competition between Bank Syariah Indonesia (BSI) and Bank Aladin Syariah (BAS) using a Game Theory approach to identify optimal strategies based on profitability, efficiency, and intermediation indicators. A descriptive-quantitative method was employed using 2025 secondary financial data, including Return on Equity (ROE), Operating Expenses to Operating Income Ratio (BOPO), and Financing to Deposit Ratio (FDR), which were transformed into a payoff matrix and analyzed using POM-QM for Windows Version 5. The results indicate that BSI adopts a dominant Profit Strategy (A1), while BAS selects a Growth Strategy (B1). The equilibrium occurs at (A1, B1) with a game value of 4, indicating a pure strategy equilibrium and an asymmetric competitive structure in which BSI maintains a relative competitive advantage. A key finding is that digitalization alone no longer provides a unique competitive advantage, as both banks have implemented digital transformation initiatives. Instead, competitive superiority depends on the ability to convert digital capabilities into sustainable profitability, efficiency, and value creation. These findings contribute to the understanding of competitive dynamics in Islamic banking and provide strategic implications for digital Islamic banks pursuing sustainable growth.
