Your children would either have the blood group A or blood group B. This is because each of you would pass half of your genes on to the child. Every trait that we exhibit has two alleles for it in the body. The dominant one is exhibited in the trait and the recessive one stays in the gene and may be passed on to the child. If it finds another recessive allele, the trait will surface. Some alleles are co-dominant, that is they both show up.
This is the case for blood group AB. You have the alleles A and B. A and B are both dominant and O is recessive. This means that whenever A or B are present, they will show up, while to be a blood group O, you would need both O and O  since O is recessive.
Therefore, your genetic make up for blood group is AB and your wife's is OO.
When you have a child, you will either pass down A to the child or B. Your wife
may pass down either of the O's too.

Let's look at a simple cross diagram to explain the probability of your
children's blood groups:

  You   Your Wife

Blood Group   AB   O
Alleles   AB   OO
Gametes   A   B   O   O
Offspring alleles    AO   AO     BO    BO
Blood groups   A   A     B   B

Hence, there is a 50% chance of your child having the blood group A and 50%
chance of it being blood group B.

Now, let's come to the rhesus factor. The rhesus factor is what the positive
and negative in a blood group represents. It show the presence (+) or absence
(-) of an antigen marking on blood cells. Positive rhesus parents can have
either a positive rhesus child or a negative rhesus child. There is no
If, however, you both were rhesus negative, then all your children  would
also have been rhesus negative.
So, you can have children with the following blood groups:

Your child can only inherit A or B from you and has to inherit o from mum , so child will be either A ( Ao) or B ( Bo) . It cannot be AB or O, nor can it be pure breeding for its A group or its B group.
Regarding the rhesus factor, your baby can only be rhesus negative if both of you are carriers for the negative factors and even then because of the mendelian 3/4 ratio it will most likely be RH pos

I think it would be ab positive.

The child's blood group must be A or B, rhesus factor could go either way.
