Sports betting on OVERDOG
This is the whole sports catalog in one place: which sports have boards, which competitions sit under each one, what you can bet on a single match, and where the season-long markets live. Every sport below has its own page, and under most of them sit pages for a league, a tournament or a tour.
The structure is the same everywhere. A sport page lists its competitions; a competition page lists its fixtures; a fixture opens the full market menu for that match. Season-long questions — who wins the title, who makes the playoffs — sit in their own futures pages instead of being buried under a fixture. Esports run on the same machinery on their own hub.
Betting is entertainment, not income — stake only what you can afford to lose.
Every sport on the board
OVERDOG carries soccer, tennis, baseball, basketball, American football, MMA, cricket, golf, hockey, Formula 1, boxing, rugby league, table tennis, volleyball, darts, lacrosse, pickleball, chess and cycling, plus a separate esports catalog. Each has its own page; which of them have a live board at any given moment depends on the season, and the depth of that board varies as much as its existence does.
The deepest boards
Soccer is the largest board on the site by a wide margin, and the one where the competition tree runs deepest — the UEFA Champions League, the Europa League and the Conference League, the Premier League, La Liga, Serie A and the Bundesliga, MLS and Liga MX, Copa Libertadores and Copa Sudamericana, and a long tail of domestic cups. Tennis is the next deepest and the most continuous: the ATP and WTA tours run through most of the year, past the Australian Open, Roland-Garros, Wimbledon and the US Open, with ITF and doubles draws underneath. Baseball runs MLB alongside the KBO in Korea, NPB in Japan and the CPBL in Taiwan, so the board spans four countries from spring through late autumn.
The North American leagues
American football runs the NFL through to the Super Bowl, with college football and the CFL alongside it. Basketball carries the NBA and the WNBA, college basketball through March Madness, and international qualifying, so there is a board in summer as well as winter. Baseball runs to the World Series and hockey to the Stanley Cup. These are seasonal by nature — a league sitting between campaigns has few or no fixtures listed, and its page fills back up when the season returns rather than being taken down.
Combat sports, motorsport and the long tail
Combat sports run on the UFC for MMA plus marquee boxing cards. Motorsport centres on the Formula 1 drivers' and constructors' championships, with markets on individual race weekends around them. Golf spans the PGA Tour, the DP World Tour, LIV and the LPGA, and the men's four majors sit across those calendars. Cricket covers international fixtures alongside franchise T20 — the IPL, the Caribbean Premier League, the Pakistan Super League — in Test, one-day and T20 formats. Rugby league runs the NRL and Super League, and the tail continues through table tennis, volleyball, darts, lacrosse, pickleball, chess and cycling. A smaller sport gets the same order-book pricing as a marquee one; what it does not get is the same depth of markets or the same liquidity behind them.
Esports has its own hub
Esports sit on a separate hub rather than inside this catalog, because the competition structure is different — circuits and majors rather than domestic leagues. League of Legends and Counter-Strike 2 carry the deepest boards, followed by Valorant and Dota 2, with Mobile Legends, Honor of Kings, Overwatch, Call of Duty, Rainbow Six Siege, StarCraft 2, Rocket League and PUBG listing when their circuits run. The share mechanic and the on-chain settlement are the same as on the sports side.
Competitions, not just sports
A sport is rarely the unit anyone actually wants — the Champions League, the NFL and the IPL are, so the catalog carries a competition layer under every sport. The larger the sport, the deeper it runs: soccer alone carries domestic leagues, continental cups and national cups across most of the football-playing world, while cricket splits into internationals and franchise T20, basketball into the NBA, the WNBA, college and FIBA qualifying, and golf into four separate tours.
A competition page lists that competition's fixtures with their live prices and links each one through to its own market menu. Where a sport's unit is a tour or a one-off rather than a league — tennis, golf, motorsport, boxing — the same layer carries the tour or the event instead, so the path from a sport to a specific match is the same everywhere. Every sport links to its own page from here, and each sport page lists the competitions currently trading under it.
Market types differ by sport
The bet menu is not the same on every board. A soccer match and a UFC fight are priced with different question sets, because the sports resolve differently, and the catalog reflects that instead of forcing one template across everything.
Moneyline, spreads and totals
The three markets that appear across most sports are the match winner, the handicap, and the over/under on a combined total. Soccer adds the draw as a third outcome, tennis has no draw at all, and the totals line varies by sport — goals, points, runs, games or rounds. Halves and periods carry their own versions on the sports where they make sense, so a first-half total or a first-five-innings result is priced separately from the full match.
Player props and sport-specific markets
Beyond the core three, each sport has markets that only exist there. Basketball prices points, rebounds and assists on individual players. Baseball has no-runs-first-inning, first-five-innings lines and extra innings. Soccer has exact score, both teams to score and team totals, in the match and in each half. UFC cards price the method of victory and whether a fight goes the distance. Tennis prices the set winner, the first set, set games and whether the match is completed. Cricket prices the toss, the top batter and the most sixes.
Season-long outrights and futures
Outrights get their own pages here instead of being buried under a fixture. These are the season-long questions: the Formula 1 drivers' championship, the Super Bowl winner, the World Series, the Stanley Cup, an NBA conference, a golf major, the T20 World Cup, a Champions League winner. Every sport that has them carries them as a separate board.
They behave differently from a match market and the pages are built for that. A futures market can stay open for months, its price moving with every result along the way, and you can sell the position back into the book before it resolves, as long as someone is bidding. It is also the part of the catalog that does not empty out between seasons: when a league has no fixtures listed, its title, playoff and award markets are still trading, which is why a sport can look quiet on the schedule and still have plenty on the board.
Where every price on this page comes from
Every number on every board in this catalog comes from the Polymarket exchange. OVERDOG is an access layer over it — a verified builder on Polymarket's own register, not a bookmaker — so it does not set a line anywhere in this catalog, on any sport, at any level of the tree. It makes no claim to be licensed or regulated in any jurisdiction, and whether you can use it depends on your local laws. Markets settle on-chain on Polygon through a decentralized oracle, and anyone can audit how one resolved.
One order book behind every sport
Each outcome trades as a share that settles at one dollar if it happens and at zero if it does not, so its price reads directly as the market's implied probability. Because the price is set by traders posting orders rather than by a bookmaker's margin added on top, there is no vig inside it. That is a statement about how the price is built and nothing more — it never implies a bet will win, and it is not a claim that betting here is free. The same mechanism runs the deepest soccer board and the thinnest darts market; what changes between them is liquidity, not pricing model.
The cost of a sports bet
A bet costs a flat 1% OVERDOG fee plus Polymarket's own fees, shown together before you commit, with no separate bookmaker margin underneath. Our share is the same 1% on every sport, from the deepest soccer board to the thinnest darts market. There are no promotions, no bonus balances and no rollover conditions here, and winning does not change what you pay or get an account limited, because the counterparty is another trader in the same book rather than a house.
