Unfortunately, Microsoft documentation does not list __int128 as an available data type, confirming its official unavailability. The syntax highlighting feature, while helpful, cannot be relied upon to indicate the existence of data types. Additionally, naming variables or types __int128 should be avoided as it may conflict with potential future compiler usage.

On x64/IPF machines, one might expect register spanning to enable __int128, similar to how __int64 is implemented on 32-bit targets. However, currently, only SIMD types such as __m128 and its variants provide 128-bit functionality within Visual Studio.
