Currently when you create a Yes/No market, it always starts out being initialized to 50%, even if you as the market creator know that the probability is highly skewed towards 0% or 100%.

Currently this can only be rectified by the market creator buying additional shares after market creation to better reflect the true probability.

This market will resolve Yes if by end-of-year 2023 Manifold adds an option at Market creation time to initialize a Yes/No market to something other than 50/50. It still counts if this costs the market-maker additional mana.

This market is about what can be done via the app and website GUI, not about what can be done via the API.
