Doubt versus Suspect

[Tom]

Hello

Please see below:

1- I doubt he has some money.
2- I suspect he has some money.

Could you please shed some light on it?

Good morning, Tom

It's basically a question of positive vs negative point of view:

NEGATIVE:
1- I doubt he has some money. =
My feeling is that he probably does not have any money.
(You should also use any in your original sentence! --> I doubt he has any money.)

POSITIVE:
2- I suspect he has some money. =
My feeling is that he probably has some money.
(The word some is correct in this sentence.)
