TMT is an acronym that can refer to several different concepts or organizations, depending on the context. The most common uses appear in finance and science, where a brief, sector-wide or project-specific designation helps keep discussions concise.

Technology, Media and Telecommunications. In market analysis and investment reporting, TMT stands for the combined Technology, Media and Telecommunications sectors. It is used to describe trends, valuations, and activity across software and hardware, internet and digital services, telecommunications networks, film and television, publishing, and digital advertising. Analysts may group companies into TMT to discuss growth prospects, regulatory risk, or consolidation activity across these related industries.

Thirty Meter Telescope. TMT also refers to the Thirty Meter Telescope, an international astronomical observatory project aiming to build a 30-meter optical and infrared telescope. The project is led by the TMT International Observatory and seeks to advance high-resolution observations of distant galaxies, star formation, and exoplanets. Proposed sites have included Mauna Kea in Hawaii and Roque de los Muchachos on La Palma in the Canary Islands. The project has faced regulatory, legal, and cultural challenges that have delayed construction and affected timelines.
