Inside the Cosmobet Sportsbook
Cosmobet's sportsbook covers 30+ sports with deep pre-match and live markets. Football fans get every major league from the Premier League to Serie A and the Champions League, alongside top tennis, basketball, cricket, MMA and esports coverage. In-play betting runs 24/7 with live odds, cash-out on most singles, and competitive prices on accumulators, BTTS, player props and Asian handicaps.
Sports & Markets
Coverage runs across more than 30 sports, with football taking the deepest schedule. League markets stretch from the Premier League and Champions League through domestic cups and Europe's other top divisions, while tennis follows the tour calendar from Grand Slams down to smaller events. Basketball, cricket, MMA and esports each carry dedicated markets, so a bettor can move between sports without leaving the account. Market availability depends on the sport and the stage of the competition.
Popular Bet Types
Singles are the simplest: one selection on one event, settled on that result alone. Accumulators combine several selections into a single wager, and every leg must land for the bet to pay. Both-teams-to-score asks whether each side will find the net, regardless of who wins. Player props focus on an individual's contribution — shots, cards or other stats — rather than the final score. Asian handicaps apply a goal or point spread that removes the draw as an outcome and evens up mismatched sides. Each type appears across the sports listed above, though not every market is offered on every event.
Live Betting & Cash-Out
In-play markets run around the clock, with odds adjusting as the action unfolds rather than sitting static until kickoff. Bettors can back the next goal, the next point or the outcome of a specific phase while an event is live. Cash-out is available on most singles, allowing a wager to be settled before an event ends — securing a return on a winning position or limiting a loss on one that has turned — instead of waiting for the final whistle. Availability and value vary by market and moment.
