Xiaomi hasn’t released its Marshmallow update plans yet, but we highly doubt if the Chinese manufacturer would push the Android 6.0 update to its budget line smartphone Redmi 1S anyway, so if you want the freshest release of Android running on your Redmi 1S (in pure vanilla flavor), know that an unofficial build of CM13 is now available for the device.
Developer rebelos over at xda has only recently released an unofficial build of CM13 for the Redmi 1s that you can install right now and get Marshmallow.
This Redmi 1S CM13 ROM is in early development stage at this moment so it comes with certain bugs and issues. However, major functionalities like RIL, Camera, WiFi, Bluetooth, SD Card and Audio are all working good.
You can grab the Redmi 1S CM13 ROM from the download link below and simply install it using a custom recovery along with Marshmallow Gapps (also linked below).

Since CM13 is an AOSP based ROM, you will also need to flash a Marshmallow compatible Gapps package separately to get Google services like Play Store on CM13. Get it from the link below:
