Wow that's BIG!

I played Fanduel for a couple years, I'm cheap, so small time bets. Then I switched to DraftKings. DK also has free offers, none that large, some are invite a friend, both get something, free bet, but they also have a new player, similar offer bet $500 and get 500 DK dollars. Which means you can bet those, but you can't withdraw them as cash. However if you win the bet, you will still get the matching DK Dollars.

I play fantasy sports all year long. NFL through the Fall and Winter, NASCAR from Spring into Fall. No sports betting in Wisconsin, so I get all those offers from both and delete them, because I'd have to drive to IL to be in a legal location. I'm not going to drive 100 miles to place a bet.

Here's what I see. If you win, no bonus. They will match any bet up to $3,000 if you lose. Here's their words and my bold.

New FanDuel customers who register through this post will receive the No Sweat First Bet offer. Their qualifying Super Bowl wager can be any amount specified within the offer’s terms and up to $3,000. A winning ticket will nullify the offer and trigger a regular cash payout. However, a loss signals FanDuel Sportsbook and rewards you with bonus bets equal to your original stake.

Up to, so you could bet $100 and get a matching $100 if you lose, anything up to $3,000.

DK has a $5 new member get $200 in bonus bets. The two of them are always offering these matching funds kind of things, for new members, but not up to $3,000. That's a good one.
