A couple of points:

  1. You don't agree to "buy it today", you "agree to buy" it today. Both exchange of payments and assets take place in the future

  2. The price of a future isn't determined by prediction any more than the asset is. The price of a future is given explicitly by the price of the underlying, suitably adjusted for cost of carry and cost of financing

First, that's not true, technically speaking. The price of the future is whatever the market clears at. Arbitrage is a strong force that keeps the future and the underlying prices in a certain relationship, true, but only under certain (though common) conditions. Second, here we are talking about NGDP futures and with them specifically there is no arbitrage against the underlying because the underlying is just an economic number that you cannot buy and warehouse. So in this particular case the price of the future is purely prediction-based.

How much appetite would there be for shorter windows on the Open Threads? Having one every 4 days would have some advantages:

  • The material would be spread out more evenly through time, rather than having the majority of the posts in the first few days of a new thread
    • The start day would vary over time

I am not sure if you are aware, but the OTs have been a monthly rather than weekly event for years until a few months ago. At any rate, I am generally not convinced that a further reduction is needed, as it will 1. It might make people even more confused as to when to post them 2. It is generally becomes more 'spammy 'and 3. The benefits of a further reduction are questionable.
