Will any new animal species of at least 1kg be discovered before 2028?
Prediction market on manifold. Living species. At least one specimen must break 1kg. (For aquatic species, this ignores the weight of water that can be easily removed, e.g. wringing out a sponge.) In order to resolve YES, the scientific community must come to recognize it as a distinct species in between market creation and close. If there was a debate over whether to consider a variation a different species, that doesn't count.
