It depends on several factors
1) you have so assume that the waters are of equal volume
2) it depends on the shape of container.
3) it depends on the temperature of the hot water and the cold water.
some people on this forum are saying that hot water freezes faster, it is possible depending on the amount of water, temperature and shape of container
here is why
if you have a plate of boiling water, and then a plate of cold water not not really close to the freezing point, the boiling water will evaporate, meaning that there will be a lot less warm water. less water to cool down, means faster temperature change. Basically for all the hot water people, they are saying that the water lost to evaporation will make the difference, because of the different volume. the heart of this theory is like this, a cup of warm water will freez faster than an ocean of cold water if they are subjected to the same cooling force.
why does the shape of the container matter? if the water is in test tubes, there is less evaporating surface and not a lot of the hot water would evaporate so the cold water will freez first.
however, in general, the cold water will freeze first, it is possible that the hot water will freeze first but it is less likely

Cold water freezes quicker, but hot water in a container that collects condensation on the outside will freeze quicker than cold water in the same container (or pipe).

It is not quite as simple as that.
If the hot water has boiled off any dissolved gases then it can cool faster and freeze quicker than a colder water that still has a lot of gases dissolved in it.
Dissolved gases can interfere with the freezing process and the formation of crystals of ice.

Cold water since it requires less energy to lower its temperature to the freezing point.

hot water and I forgot why but this is right for sure
