New Hampshire legalized sports betting through HB 480 in 2019, and the New Hampshire Lottery awarded a single statewide mobile contract to DraftKings, which launched on December 30, 2019 with then-Governor Chris Sununu placing the first legal wager. DraftKings is the exclusive online sportsbook in New Hampshire and pays the Lottery 51% of mobile gross gaming revenue (and 50% of retail revenue), one of the highest revenue-share rates in the country, with proceeds directed primarily to the state education trust fund. The original contract runs for six years with options for two two-year extensions. The minimum betting age is 18, one of the lowest in the U.S. legal sports betting market, and bettors must be physically located in New Hampshire.
Regulatory Body: New Hampshire Lottery Commission · Legal since December 2019 · Tax rate: 51% on revenue (to the state via lottery contract)
The best sportsbooks combine competitive odds, a broad betting market selection, and a mobile app that performs under pressure — especially during high-traffic events like NFL Sunday or March Madness. Start by comparing the juice (or "vig") on standard spreads and moneylines: a sportsbook consistently charging -115 instead of -110 is costing you meaningful money over time. Evaluate the live betting interface separately from pre-game — many books have strong pre-match offerings but laggy in-game experiences. Withdrawal options and processing times are often overlooked until you have a balance to cash out, so research them before you sign up.
Legal sports betting in New Hampshire operates within a framework set by state law and enforced by a gaming commission or equivalent regulatory body. When you place a bet, your position is against the sportsbook's lines, which are set to attract balanced action and guarantee a margin for the operator. For every wager, you are paying a small commission embedded in the odds — this is the vig. Understanding this is fundamental: the house always has a built-in edge. Licensed operators in New Hampshire are required to use geolocation software to verify you are physically within state borders when placing each bet.
Having accounts at two or three sportsbooks and comparing odds before placing each bet — a practice called line shopping — is one of the most straightforward ways to improve your long-term results. The difference between -110 and +100 on the same side of a bet is significant compounded over hundreds of wagers. Most experienced bettors maintain at least two accounts specifically to ensure they are not leaving value on the table. Line movement also provides information: a line that moves sharply before a game often reflects sharp-money action, which can be a useful signal when evaluated in context.
Betting on your favorite team is a persistent mistake — emotional attachment distorts analysis. Chasing losses by increasing bet size after a losing streak is another, and it accelerates bankroll erosion. Parlays are the most aggressively marketed bet type because they carry the highest margin for the sportsbook; occasional small parlays are fine for entertainment, but making them a primary strategy is a losing proposition. Finally, ignoring unit sizing in favor of betting varying percentages of your bankroll based on confidence is a form of gambler's fallacy.
