When Texans star JJ Watt set up an online fundraiser to help Houston in the aftermath of Hurricane Harvey he hoped to raise $250,000. Now just a few days later, it's raised $8.5 million and quickly on its way to $10 million.

Watt revealed the exciting news Wednesday evening on Twitter after appearing on the Ellen DeGeneres Show earlier in the day.

Ellen announced that Walmart would be contributing $1 million to Watt's effort.

"Can't speak enough to the goodness in humanity, to everybody helping out," Watt said Wednesday night.

Watt donated $100,000 himself when the YouCaring fundraiser first went online.

"That's our city. It's very tough to watch our city get hit by such a bad storm and not be there to help with the recovery," Watt said. "I know these recovery efforts are going to be massive."

He said he wanted to start a fundraiser to help people get back on their feet. "Houston, we're in this together," Watt said in a description of his donation on the fundraising page.

The initial goal was smashed within hours, so Watt raised the goal to $500,000 and has kept raising the bar since.
