The fantasy platform is giving new customers a 50% first-deposit match worth up to $1,000 plus a free survival-style contest entry as Big Ten play resumes Friday.
Underdog Fantasy is promoting a new-customer offer tied to Friday night's Big Ten matchup between Indiana and Northwestern. New users who sign up with the code YAHOOBONUS receive a 50% match on their first deposit, worth up to $1,000 in bonus funds, along with an entry into a free-to-play survival contest called Keep Your Million.
The deposit match requires a minimum of $10 to activate. Because the match rate is 50%, a deposit of $2,000 is needed to receive the full $1,000 in bonus funds. A $500 deposit, for example, would return $250 in bonus money. The bonus funds are not directly withdrawable and are subject to a one-time playthrough requirement before any withdrawal.
Keep Your Million is free to enter and does not require a deposit. Players begin with a virtual pot valued at $1,000,000. Each round presents a higher-or-lower question based on a player projection, and the full balance must be allocated between the two sides. The process runs for up to 20 rounds, and whatever balance survives is awarded as Underdog bonus funds rather than cash.
The offer is available to new customers in roughly 40 states plus Washington, D.C., with eligibility varying by location. The standard minimum age is 18, though it rises to 19 in some states such as Alabama and Nebraska, and to 21 in Arizona, Massachusetts and Virginia. Underdog also operates a separate prediction market with its own list of eligible states.
On the field, Indiana enters Big Ten play in strong form. The reigning national champion opened the season with three lopsided wins over non-conference opponents and is heavily favored against Northwestern, which arrives off a dominant win over Colorado.
Yahoo's associated pick'em analysis highlighted three player projections for Friday's game. The selections favor Indiana quarterback Josh Hoover going over 245.5 passing yards, Northwestern quarterback Aidan Chiles finishing under 174.5 passing yards against a stout Indiana defense, and Indiana running back Turbo Richard landing under 89.5 rushing yards because of the team's depth at the position.
Hoover built a reputation as a high-volume passer during his time as the starter at TCU, and the analysis suggested Indiana coach Curt Cignetti could lean on his arm Friday night.
The offer's details were verified as of September 25, 2026. Underdog directs customers concerned about their play to national and state problem-gambling helplines, including 1-800-GAMBLER and the National Council on Problem Gambling at ncpgambling.org.
