Creating your own markets is coming in Phase 2 - starting June 1st. The only reason we are delaying it because we are not charging any fees yet.

In an LMSR/AMM (Automated Market Maker) you need subsidize a market with initial liquidity. If you don't charge fees, you're basically running the market in loss in a thinly traded markets. So far we've been running all out markets in loss.

That being, if we introduce market creation by users without any fees - there will be no incentive for the creators. No one would want to create the markets at loss.
