It happened at around 12:35am at an address on Chicago's South May Street.
Four of those injured are said to be in a critical condition, while the other victims are said to be stable.
CNN reports that the victims range in age from 16 to 48.
Police say two people are being questioned.

He explained: "We had an incident where there was a party.
"Inside, there was a dispute, and shots were fired... several shots.
"People started to spill out, and as they spilled out more shots were fired... [and] more shots were fired at another location."
