Quick Answer
Esports prediction markets can cover Dota 2 Internationals, CS Majors, League of Legends Worlds and per-tournament or per-match outcomes. Opinion has listed esports markets, but catalog and liquidity change by event. This guide explains the mechanics and the checks users should make in the live order book before choosing a venue.The trading mechanics are similar to other prediction markets, but esports contracts require extra attention to patches, rosters, formats and resolution sources.
What Counts as an Esports Prediction Market
A prediction-market contract tied to an esports outcome — tournament winner, match result, map-level result, in-tournament prop. Examples:- “Will Team Liquid win The International 2026?”
- “Will G2 Esports advance from CS Major group stage?”
- “Will the LoL Worlds 2026 finals go to 5 games?”
- “Will the Dota 2 TI 2026 winner be from China?”
Why Esports Markets Are Different
Esports contracts require checks that do not always appear in traditional sports markets:- High match cadence. A tournament can contain many matches in a short period, so market availability and resolution timing can change quickly.
- Game patches. A balance update can change the competitive context after a market is created.
- Roster volatility. Substitutions, transfers and eligibility decisions can affect both expectations and the exact settlement rule.
- Format details. Online versus LAN play, map vetoes and best-of-three versus best-of-five series are materially different contract contexts.
How to Compare Esports Platforms
Coverage changes quickly, so use this as a venue checklist—not a permanent ranking:
Opinion has listed markets for titles and events including:
- The International (Dota 2) — winner, group, per-series markets
- CS Majors — winner, advancement, per-match
- League of Legends Worlds — winner, region winner, per-match
- Valorant Champions — winner, per-match
- Mobile esports leagues (PUBG Mobile, Mobile Legends — varies by region)
Major Esports Events to Check
Large events can attract prediction markets, but schedules and catalogs change. Verify the organizer’s current event page before relying on a date or assuming a contract is listed.
High-profile events may draw more attention, but the presence of a market does not guarantee deep liquidity or tight pricing.
Fees, Spread and Price Impact
Do not compare an esports sportsbook’s embedded margin with a prediction market’s headline fee alone. The prediction-market cost can also include the bid/ask spread and price impact, which can be material in a thin match or map market. On Opinion, the current published policy charges takers0%–1%; makers are not charged. The current minimum order is $5 and the minimum fee is $0.25. The exact preview depends on the market, price, order size and discounts. Verify it in the live app and the official fee documentation.

Per-Match vs Tournament-Winner Markets
Per-match and tournament-winner markets have different time horizons:- A per-match contract usually covers one match or series
- A tournament-winner contract remains open across the event
- Different matches can be affected by the same roster, patch or bracket, so their outcomes are not inherently independent
- Actual close and resolution timing depends on the contract rules, official result source and any review period
Research Factors to Check
Before treating two esports prices as comparable, verify:- Patch version. Confirm which game version applies and whether a scheduled update falls before the match.
- Roster status. Check confirmed starters, substitutes and tournament eligibility.
- Series format. Best-of-three and best-of-five contracts have different rules and time horizons.
- Venue and schedule. Online versus LAN play, travel and back-to-back matches can change the information participants consider.

A Note on Regulation and Local Rules
Esports prediction markets exist in a different regulatory landscape than traditional sports books, particularly in jurisdictions that license sportsbooks but haven’t addressed prediction markets explicitly. Check your local rules before trading; availability varies.Where Opinion Fits
Opinion has listed markets across major esports titles, while other venues may list overlapping headline events. Because the live catalog and depth change by tournament, compare the exact market and order book instead of treating a historical category snapshot as a permanent ranking.

What to Watch
Esports prediction markets move differently from traditional sports markets — patches, roster swaps, and online-only formats inject specific kinds of volatility:- Patch days. A balance patch can re-price every market in a game overnight. Check the patch schedule before holding positions through one.
- Roster swaps. A mid-season transfer can change how participants price a team; the size of the move depends on the player, format and liquidity.
- Online vs LAN format. Confirm the venue and whether a contract’s wording covers a format change.
- Map veto and series length. Best-of-three and best-of-five series are different contexts; read the exact match and settlement terms.
