Are sportsbook sign-up bonuses worth claiming?

Yes — first-bet bonuses and deposit matches offer guaranteed +EV when used correctly. A typical offer: "Bet $1000 risk-free" means if you lose, you get a free bet credit (worth roughly 70% of face value). The key: use your first bet on a slight underdog at +odds to maximize expected value. Read the rollover requirements carefully — some bonuses require 5-10x wagering before withdrawal.
