Nate's Food Company (NHMD)

[shotsky]

There isn't just one spread. Each MM has its own spread. What you see at your brokerage is what that brokerage advertises - typically the MM that the brokerage hands off to. Here's what etrade has for now:
NHMD
NATE S FOODS CO COM
$0.0015+0.0001 (+7.14%)
Bid x Size
$0.0013 x 32,626,077
Ask x Size
$0.0015 x 19,214,547
That means they will BUY up to 32,626,077 at $0.0013
That means they will SELL up to 19,214,547 at $0.0015
That is not the only spread, it is the only one that Etrade shows.
If any trader makes a trade that falls within that window, the MM must execute the trade. And, because they are willing to buy more than they are willing to sell, they need more shares, because they anticipate higher demand and a rising price.
Those trades by those quantities are called tranches. MMs can and do change their spreads between tranches.
