The account was created Monday by Steve Sisolak, the Clark County Commission Chair from Las Vegas.
It's considered the deadliest mass shooting in modern U.S. history.
"I'm truly overwhelmed by the outpouring of donations to the Las Vegas Victims' Fund from all over America", Sisolak wrote on Twitter. "The first thing when we got up [on Monday] morning, everybody, personally, got it together and made sure anybody they know or love was OK".
It won't be just the Raiders sending money, as the NFL Foundation will match the Raiders' donation.
The initial terror of an active shooter situation is over but as hundreds recover, the need for life saving blood is increasing.
Blood has a shelf life, officials say, so it is important that donations are given on an ongoing basis.
Dozens of walk-in donors showed up at Bonfils Blood Center Monday after learning about the deadly mass shooting in Las Vegas- ready to give blood.
"We mourn with the families of those who perished and hope for the speedy recovery of the more than 400 people who were reported injured", Foreign Affairs Chief Alan Cayetano said in the statement. She explains in the simulations, about 20 volunteers act as though they are victims, allowing those in the trauma center to practice evaluating and treating patients quickly.
