Yeah, I think the budget on all of them is supposed to be around $150M-$200M.
Of course don't let the large budget like that make fool you into thinking everything should be the same as the movies. The movies get those budgets for 2-2.5 hour films. These shows are getting these budgets for 5.5-6 hours, meaning that you have to expect things to be scaled down a bit like we've seen. A two-hour film with a $200M budget is going to be able to afford a lot more than a $200M show that has to spread that budget over 6 hours - basically the equivalent of making 3 theatrical movies on the budget of one.
