Underdog Fantasy New User Deposit Match by State

Underdog Fantasy is offering a first-time deposit match for new users as of August 31, 2026, with the size of the Bonus Funds depending on where you play. Eligible players in CT, HI, ID, IA, LA, ME, MT, and WA can claim a 100% match up to $250 in Bonus Funds.

In other states with an Underdog product - AL, AK, AZ, AR, CA, CO, DE, DC, FL, GA, IL, IN, KS, KY, MA, MD, MI, MN, MS, MO, NE, NH, NJ, NM, NC, ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WV, WI, and WY, the offer is a 50% first deposit match up to $1,000 in Bonus Funds. That extra bankroll arrives just before the 2026 NFL regular season starts on Wednesday, September 9, when the Patriots visit the Seahawks, followed by the 49ers-Rams game in Australia and a packed Sunday-Monday Week 1 slate.

How to Use Underdog Bonus Funds for NFL Week 1 and Beyond

New users can put the match to work immediately on Week 1 Best Ball drafts, Pick’em cards, and other fantasy contests without committing as much of their own cash to opening-week projections. After the first slate, the same Bonus Funds can seed more Best Ball teams for the rest of the season, cover midweek injury-driven Pick’em entries, and keep players active through bye weeks and late-season races.

Bonus Funds typically apply to qualifying fantasy entries, often require a 1x playthrough, and may expire within a limited window such as 14 days, so the most effective strategy is to use them on Week 1 contests and then roll winnings into later drafts and weekly slates. Availability, products, and exact terms vary by state, so confirm the current offer in the Underdog app before depositing.
