That is a prediction. It is not a statement. I made a similar bet with my wife. The difference is in intent.

There are people like Charlie Ward that say things like, "This already happened yesterday and I'm the only one who knows about it. Also, I spoke with my super secret insider, and he told me this super top secret information that I'm now telling you and the whole world." "Dr." Ward makes statements of fact that are in the moment unprovable, intended to make himself look like an authority, likely to purposefully mislead.

Jaun said "I think this will happen by this day." I have zero problem with that. He made it clear it was his prediction, not something he knows from some external source that told him so.
