This study analyzes the investment opportunities and challenges in Indonesia's mining sector amid volatile global commodity prices and shifting macroeconomic conditions in 2025-2026. Despite its strategic role as a source of foreign exchange, state revenue, and downstream mineral industry development, the mining sector's contribution to Indonesia's Gross Domestic Product declined from over twelve percent in 2022 to below nine percent in 2025, becoming the only major economic sector to contract even as national economic growth remained solid. Using a descriptive qualitative method based on secondary data from government publications, stock exchange authorities, and financial media, this study examines the sector's macroeconomic environment, the financial performance of listed mining companies, and the interaction between commodity cycles and monetary policy. The results show divergent performance across subsectors, with gold and nickel producers recording strong profit growth while coal producers faced declining revenue amid weaker global coal prices; despite short-term market corrections, foreign investors continued net buying of selected mining stocks, reflecting sustained long-term confidence. The analysis identifies mineral downstreaming, the global energy transition, digitalization, and government policy support as the main investment opportunities, while global economic uncertainty, commodity price fluctuation, regulatory change, and environmental and governance risks remain the principal challenges. The study concludes that Indonesia's mining sector offers a high-risk, high-return investment profile best suited to investors with a medium- to long-term horizon, and recommends portfolio diversification across commodity subsectors, close monitoring of macroeconomic indicators and regulatory developments, and a gradual investment strategy to manage short-term price volatility
