That $99M horse's ratings aren't desirable. I very much doubt anyone will buy that horse for so much, considering comparable horses are being offered for $5,000 or less. I see a bunch of comparable stallions that are being offered for just $1,500. So, no. No one is going to buy that horse for so much.
Remember, a horse is only worth as much as someone is willing to pay. You can try to sell a horse for as much as you want, but if no one buys it, then the horse is not actually worth that much.
