Sometimes, Market Makers want a larger spread between the bid and ask on volatile price days. They "make a market" buying from a seller even without a current match for that sale and on volatile days they want more "cushion", so they widen the spread. They are constantly looking at their "order book" of buy and sell orders and they set the spread accordingly. That is why when this launches, I won't have a sell order in at close to the current price point, I am not showing them my intents, especially the first day. I will have some sell orders in way higher, in effect, sending them a message, up, up, up to get those shares.
