Today is the fifth day since the 2026 FIFA World Cup kicked off, and the tournament has produced its first major upset. Spain, a tournament favorite with a squad valued at €500 million, was held to a 0-0 draw by a 40-year-old goalkeeper from Cape Verde worth just €50,000. Netizens joked: How can a human foot possibly beat the "foot of Buddha"?

To all the fans who bet on tournament favorite Spain, I have to ask: How are your hearts and wallets holding up?

Favorites stumbling, dark horses emerging, stoppage-time daggers—this 48-team World Cup has barely begun, and it's already slapping the "on-paper strength theory" hard in the face. In other words, underdogs overcoming favorites, the weak defeating the strong—perhaps that is the true charm of competitive sports.

So here's the question:

Have you ever cheered for your team and predicted scores in your group chats?

Have you ever participated in predictions, either offline or on regulated platforms?

In fact, the kickoff of this World Cup spectacle isn't just a battle among 48 teams on the pitch; it's also a head-to-head battle among several prediction products.

If you open Polymarket, you'll find it has prominently placed a World Cup entry with a golden soccer icon in its top navigation. Click further, and the entire tournament's matches, play methods, bracket charts, and maps are laid out in a row.

Currently, regarding World Cup predictions, there are roughly three different types of prediction methods: first, traditional official sports lotteries; second, traditional online betting platforms; third, emerging crypto prediction markets, which can be further divided into more mature ones like Polymarket and Kalshi, and new on-chain projects like Opinion and Predict.fun.

While all are predicting the World Cup, superficially answering the same question—who will win?—the underlying product logic, transparency, compliance paths, and user experience cannot be lumped together.

Next, Biteye will deliver a sharp review, from solid to shoddy, of the overall experience of betting on the 2026 World Cup across four different channels and multiple platforms.

First, the "From Solid to Shoddy" Table

To prevent everyone from getting dizzy amidst jargon like odds, contracts, and payout indices, let's first rank them directly from solid to shoddy across five dimensions:

One-sentence sharp review:Polymarket is the trending search list for World Cup markets, with Opinion close behind; Predict.fun is the best at handing out rewards for World Cup event operations on BNB Chain; Kalshi is the exchange that watches the game in a suit; traditional betting platforms are the fully-loaded, time-tested betting supermarkets; and the sports lottery is the officially stamped viewing condiment.

1️⃣ Market Expression: Can I understand what it's selling?

If you're new to World Cup predictions, the odds on traditional betting platforms might leave you a bit confused.

Traditional betting platforms use the most classic odds language, like +450, +850, +1000. Veteran players might get it instantly, but new users might stare blankly for three seconds first—these numbers look tempting, but why do I have to solve such complex math problems? Similarly, the profit mechanism of China's sports lottery is essentially still an odds menu, requiring a round of conversion rather than presenting an intuitive market price.

Whether it's veteran prediction platforms like Polymarket and Kalshi, which calls itself an event contract exchange, or newcomers like Opinion and Predict.fun, the communication advantage of prediction markets lies in not needing to convert odds or understand a bunch of market jargon. Instead, they turn the World Cup into a visible, real-time probability curve.

For example, Spain at 16¢, France at 16¢, Portugal at 11¢—this corresponds to the market believing their championship probabilities are roughly 16%, 16%, and 11%. If the Spain you backed at this moment ultimately wins the championship, you'll capture the multiple increase from 16% to 100%, roughly 6.17 times.

This market language is very friendly for newcomers wanting to participate in World Cup predictions. It's not so much that it makes betting easier, but rather that it makes it easier to judge the direction of market sentiment.

At the same time, data from this type of prediction market is naturally suited for media citation, because it turns the subjective judgment of "which team is stronger" into a real-time price voted on with money.

This round is more complex and heavily dependent on user habits. Tentative ranking by communication attributes:

Solid: Polymarket / Kalshi / Opinion / Predict.fun, where probability is the price, best suited for communication.

Above Average: /

NPC: /

Shoddy: The odds menus of traditional betting platforms/sports lotteries are not friendly to newcomers.

2️⃣ Transaction Transparency: Can I see how others are betting?

Understanding the price is just the first step. What's truly critical is: How did this price come about?

This is also the deadliest blow dealt by emerging prediction markets to the traditional bookmaker model. While prediction market data doesn't necessarily represent the "truth," at least we can intuitively see how the market is trading.

Polymarket publicly displays price, volume, order books, liquidity, price curves, and market heat. Kalshi, Opinion, and Predict.fun are similar, all showing market data, transactions, and price changes. In comparison, due to compliance requirements, Kalshi's data resembles formal financial reports more, while Opinion and Predict.fun are more like complete tournament specials within new on-chain projects.

Traditional betting platforms are different. Bettors can see payout indices or odds, but it's hard to see the actual transaction volume behind a specific market, how funds are flowing, or what the market depth really is. Traders place bets more by trusting the platform's reputation. This isn't to say they lack liquidity, but the real problem is: this liquidity is not transparent to ordinary users. It's like eating delicious braised chicken but worrying if it's made from frozen pre-made ingredients.

China's sports lottery has macro-level regulation, so outrageously manipulative bookmaker schemes are basically non-existent. However, behind every market's odds lies an opaque, inscrutable black box.

So this round's sharp review is simple:

Solid: Polymarket / Kalshi / Opinion / Predict.fun, the foundation of prediction markets.

Above Average: /

NPC: China's sports lottery, officially endorsed, massive volume, but the process is invisible.

Shoddy: Traditional betting platforms, completely black box.

3️⃣ Variety of Play: Can I choose to bet on the details I like?

If we're comparing who's best at creating gimmicks, traditional betting platforms are still the old hands.

Champion market, handicap, over/under, correct score, half-time/full-time, corners, yellow cards, player goals, Golden Boot, parlays, same-game parlays, in-play betting, early cash-out... Traditional betting platforms dissect almost every detail of a World Cup match into dazzling items on a betting supermarket shelf.

This is also the strongest and most dangerous aspect of traditional betting platforms: the more play methods there are, the easier it is for users to feel "there's always one angle I can understand." But for the betting platform, the finer the play methods, the longer users stay, the higher the transaction frequency, and the greater the profit.

China's sports lottery isn't lacking either. During the World Cup, play methods like champion, champion/runner-up, win-draw-loss, correct score, total goals, and half-time/full-time basically cover the prediction needs most familiar to Chinese-speaking users.

In comparison, Kalshi is catching up in this direction, starting to offer more event contracts like single matches, over/under, and both teams to score.

Polymarket, on the other hand, is more restrained, focusing on core markets like champion, advancement, and single-match winners. For instance, as of June 15, the trading volume for the World Cup champion prediction on Polymarket has already exceeded $2 billion. In contrast, liquidity for split markets like over/under and handicaps for individual matches is generally low, and corresponding markets for traditional soccer parlay bets spanning several matches are rare.

Opinion and Predict.fun are more proactive among new on-chain platforms, both featuring markets for champion, group stage, knockout stage, Golden Boot, top assists, and more.

So for this round:

Solid: Traditional betting platforms, the betting buffet.

Above Average: Opinion / Predict.fun, actively seizing market share.

NPC: Kalshi, adding dishes / Sports lottery, the official set menu is sufficient.

Shoddy: Polymarket, the signature dish is strong, but the menu is limited.

4️⃣ User Access & Compliance: How do I get in & can I get out?

This point is especially important for users in Chinese-speaking regions.

The advantage of the sports lottery is its clear compliance identity and familiarity within the Chinese context. In daily life, you can't walk far without seeing an outlet bearing the sports lottery sign. But its disadvantage is also obvious: you can't just open a webpage and participate; formal channels still emphasize physical offline outlets.

The access logic for Polymarket, Opinion, and Predict.fun is more Web3. Wallets, stablecoins, on-chain assets—relatively convenient for those with a crypto background; but for ordinary fans, wallets, private keys, USDC, and regional restrictions are all barriers. At the same time, all three face the issue of compliance for crypto prediction markets.

In comparison, Kalshi leans more towards the logic of US-compliant financial accounts. Its rules are clear, championing the regulated event contract route, but KYC, regional, and account requirements mean it's not a product designed for all global users.

Traditional betting platforms appear to have many entry points in many regions, but they also have the most problems: geographical restrictions, deposit/withdrawal risks, account risk control, and uneven platform compliance. Even if some markets in Europe and America have mature licensing systems, users in Chinese-speaking regions need to exercise caution.

So, the most important thing isn't which platform is the most thrilling to bet on, but:

Where does the money come in from?

How are the results settled?

Can the money get out?

Who can you turn to if the platform has issues?

This round:

Solid: China Sports Lottery — the most formal and familiar in the Chinese-speaking world, but requires offline channels.

Top-tier: Polymarket/Opinion/Predict.fun — crypto-user friendly, with barriers for ordinary users, and compliance yet to be tested.

NPC: Kalshi — access limited to U.S. users only, with clear compliance.

Bottom-tier: Traditional betting platforms — deposit/withdrawal and compliance risks require the most vigilance.

5️⃣Event incentives: Should I bet more for the rewards?

As a rising star in on-chain prediction markets, Predict.fun invested $2 million in a dedicated incentive campaign during the World Cup. It ran the Predict Cup on BNB Chain for the World Cup, offering a generous prize pool and using Fan Points, team lineups, leaderboards, and round-based rewards to create a series of on-chain World Cup activities.

This is very attractive to users: you’re not just predicting match outcomes, but also chasing points, climbing the rankings, and earning rewards.

Traditional betting platforms also went all out for the World Cup — after all, it’s a fan carnival that comes once every four years, and traffic is practically equivalent to revenue.

Meanwhile, Polymarket, Kalshi, and Opinion’s focus remains on the market itself: price, volume, order books, and dissemination. They did not create separate incentive programs for the World Cup.

The Sports Lottery emphasizes public welfare and rational purchasing. Although it often runs promotions, in the Chinese-speaking context it is not appropriate to expand into traffic-driving introductions.

But amid the excitement, it’s worth asking one more question: Am I enjoying the game, or trading for points? Am I watching the odds, or being pushed along by the leaderboard?

This round:

Solid: Predict.fun — the most aggressive World Cup-specific operations.

Top-tier: Traditional betting platforms — the golden period of the World Cup.

NPC: Polymarket / Kalshi / Opinion — incentives are not the main selling point.

Bottom-tier: Sports Lottery — emphasizes rationality and public welfare attributes.

Summary

The 2026 World Cup has placed several sets of product logic on the same table.

China Sports Lottery says: The match can be a spectator interaction within the framework of an official public welfare lottery.

Traditional betting platforms say: The match is a highly mature entertainment product.

Polymarket says: The match is a real-time fluctuating probability market.

Kalshi says: The match is a regulatable event contract.

Opinion says: An on-chain prediction market can also be done like a full-fledged tournament feature.

Predict.fun says: The World Cup isn’t just about betting lines; it can also be an on-chain points game.

But what may truly be worth paying attention to is not who can replace whom, but that World Cup betting lines are transforming from closed-odds products into an open, real-time, and shareable information market.

Sports is just the stage. The bigger business is humanity’s eternal desire to price the future, and to price their own judgment.
