Esports betting with crypto

Bet on esports with crypto at real exchange prices. OVERDOG lists match, map, handicap, total and tournament markets across the major competitive titles, priced by traders on Polymarket's order book rather than by a bookmaker padding the line. Fund with Bitcoin, Ether or a stablecoin, skip the identity check, and settle on-chain.

That makes OVERDOG an esports betting site of a specific kind: an access layer to an exchange, not a sportsbook. The live board above previews the open matches; this page explains the markets and the money.

Betting is entertainment, not income — stake only what you can afford to lose.

How to bet on esports with crypto

To bet on esports with crypto, deposit a supported coin, pick a market and buy shares at the exchange price, with no identity check at any step. Bitcoin, Ether, Solana, BNB, USDT and USDC all work; each converts to the same dollar unit, so your coin changes how you fund, not what you win.

Sign-in uses Google or Telegram, and you can export your wallet and withdraw anytime.

Deposit a supported coin; it converts to Polymarket's US-dollar stable unit on Polygon, which every position is priced and settled in.
Pick a market — the match winner, a map handicap, a total — and buy shares at the order-book price.
Confirm once you see the cost: a flat 1% OVERDOG fee plus Polymarket's own fees.
Sell early at the current price, or hold to settlement, where each winning share redeems for one dollar, then withdraw back to crypto.

Open the markets

Esports odds and lines: the markets on the board

Esports odds come in a small set of market types that repeat across titles: the series result, single maps or games, handicaps, totals, in-game props and outrights. Every outcome is a share on Polymarket's order book that redeems for one dollar if it wins, and the odds show its current buying price in decimal form. The board above carries the live numbers.

Match winner

The match winner settles on the series result: who takes a best-of-one, a best-of-three (BO3) or a best-of-five. It is the esports moneyline, the headline market on almost every event and sometimes the only one. Each side trades as its own share, priced as the market's estimate of that side taking the series.

Map and game winner

Most series also list a winner for each map or game — Map 1, Map 2 and onward — since a favorite can drop one and still take the series. Shooters count maps; the MOBAs count games. That ladder usually stops one map short: whoever wins the decider wins the series, so it rarely gets a market of its own.

Map and series handicaps

A map handicap, also called a series handicap (a game handicap in the MOBAs), gives one side a head start on the series score. A favorite at -1.5 maps must win by two or more; the underdog at +1.5 covers by winning or losing by one. The line does not always widen with the format: at -1.5 in a best-of-five, a sweep is no longer needed. Round-based shooters can add a rounds handicap per map, its line set match by match.

Totals: maps and rounds

Totals ask how long or how close, not who. Total maps is a bet on series length: over 2.5 in a best-of-three means it reaches a decider. The round-based shooters can add a rounds total per map, and the MOBAs can list kill totals game by game. Lines sit on the half, so a total never lands exactly on the number.

In-game props: kills and objectives

Props settle on something inside a game rather than the result: which side draws first blood, whether both teams take a major objective, whether total kills finish odd or even, or whether a game produces a rare multi-kill. Most are simple Yes-or-No questions, and they vary by title — the MOBAs carry the widest range, some titles none.

Tournament winners and other outrights

Outrights price a whole event rather than a match: who wins a league split, a major or a world championship. Each contender trades as its own Yes or No market, and prices move as results land. Other outrights cover qualification for a championship and annual awards; a title's futures page lists the open ones.

Live esports betting

Live esports betting here means trading on Polymarket's order book while the match plays out. Prices move as rounds, teamfights and objectives fall, and each buy fills at the best price sellers are asking at that moment or not at all — there is no line to be moved against you.

A sportsbook sets and moves its own in-play line. On an exchange the live price is simply where buyers and sellers last met, so it moves as fast as the traders following the match.

Cashing out is selling: any position can go back to the book before settlement, in full or in part, at the price buyers are paying then. Take-profit and stop-loss orders sell at a level you set and run on the server, so they fire even with the page closed.

Which esports you can bet on here

You can bet on the major competitive titles across the main esports genres, each with its own page of matches and a deeper guide. Genre sets the market shape: MOBAs count games, round-based shooters count maps and rounds, and a battle royale runs mostly on outrights.

League of Legends counts its series in games, all on the same map, with kill totals and props on dragons, barons, inhibitors and multi-kills. Dota 2 shares that shape, adding first blood, Roshan and barracks props. Mobile Legends and Honor of Kings bring the format to phones, with game winners and totals.

In CS2, teams pick and ban their way through a map pool, and each map typically carries a rounds handicap, a rounds total and odd-or-even props. Valorant follows the same map-and-rounds pattern. Rainbow Six Siege, the attack-and-defend shooter, lists match and map winners, the map handicap and total maps.

Call of Duty series switch game mode from map to map, and Overwatch rotates map types with different objectives, so both center on match and map markets. StarCraft II is the one-on-one outlier, a real-time strategy duel with match, map, handicap and total-maps markets. Rocket League, the car-soccer title, lists game winners within each series.

PUBG breaks the head-to-head mold: a battle royale lobby scored on placement and kills across many matches, so its markets lean toward outrights on who wins an event.

Why these esports odds carry no vig

These esports odds carry no vig because no bookmaker sets them. Each price comes from Polymarket's order book, where traders take opposite sides of the same market, so nobody builds a cut into the quote.

A sportsbook prices both sides of a match so their implied chances add up to more than a fair book would; that overage, the vig, is its edge on every bet. Paste a bookmaker's line into OVERDOG's no-vig calculator to see how much of the price is the book's cut.

What trading here costs is separate and disclosed before you confirm: a flat 1% OVERDOG fee plus Polymarket's own fees. No-vig describes the price, not the result — it never makes a bet more likely to win.

Betting esports on Polymarket with OVERDOG

OVERDOG is an access layer to Polymarket, the prediction-market exchange: your esports orders go to its order books, and every market settles on-chain on Polygon, where a winning share redeems for one dollar. Results come from the exchange's oracle, not OVERDOG, so no one here can void a market or re-grade a result.

Your orders trade against other traders, never against the house, so winning consistently never gets an account limited or closed. You can export your wallet after re-authenticating and withdraw anytime — we can't freeze you — and the settlement proof page shows how to check any resolution yourself.

FAQ

What is esports betting?

Esports betting is wagering on professional video game competitions: who wins a series, a map or a whole tournament, and what happens inside the games. It works like sports betting, with the bet types adapted to maps, rounds and kills. On OVERDOG those bets trade on an exchange, at prices other traders set.

Is esports betting legal in the US?

It depends on the state: some allow esports wagering at state-authorized sportsbooks, others restrict it, and checking the law where you live is your responsibility. OVERDOG is not a sportsbook and does not serve US residents into the global order books, because the global Polymarket exchange it routes to does not open new positions from the US. This is not legal advice.

How are esports betting odds calculated on an exchange?

No bookmaker calculates them. Each outcome is a share that pays one dollar if it wins, and its price is wherever buyers and sellers on Polymarket's order book meet — the market's implied probability. Decimal odds equal one dollar divided by the lowest asking price, and they move as traders react to drafts, form and results.

How do esports betting payouts work here?

Each winning share redeems for one dollar at settlement, so your payout in dollars equals the number of winning shares you hold. A lower price buys more shares per dollar staked, which is what longer odds mean. You can also sell before the result at the current price.

What is the house edge in esports betting, and is there one on an exchange?

The house edge is the cut a bookmaker builds into its odds, so the implied chances add up to more than a fair book. On an exchange no house takes the other side, so no edge sits in the price. You still pay a flat 1% OVERDOG fee plus Polymarket's own fees, and the spread between buyers and sellers.

What is a round handicap in esports betting?

A round handicap is a spread on rounds won on one map, offered in the round-based shooters. A side at -3.5 must win the map by more rounds than the line; the side at +3.5 covers by winning the map or losing it by fewer. Lines vary by match and sit on the half, so the bet cannot tie.

Can I bet on esports live with crypto?

Yes. Esports markets keep trading while a match plays out, so you can buy in after the first map, add to a position or sell before the end at the current price. Funding is the usual crypto deposit, with no identity check. Live prices move fast, so check yours before you confirm.

Is there an esports betting app?

There is nothing to download. OVERDOG runs in the web browser, on a phone as well as a desktop, with the same board, betslip, deposits and withdrawals on both. Open the site in your phone's browser, sign in, and every esports market is a tap away.
