I\u2019m not sure anyone really knows which will be more accurate for World Cup 2026<\/strong> match outcomes, Polymarket<\/strong> and Kalshi<\/strong> or conventional sports bookmakers. It\u2019s not even clear that one will outperform the other on average. But, at least in principle, the crowd-forecasting and prediction market algorithms can be more accurate than the bookmaker algorithms. For some exceptions where bookmakers still have the edge, see the final sections of this article. Betting will always depend on uncertain (and sometimes unfair) events. But, fortunately, not all uncertain events are created equal, and bookmakers do not read minds.<\/p>\n

The pricing model gap: house margin vs crowd consensus<\/h2>\n

This market-based approach to pricing is innovative and, for some areas, highly effective. Sportsbooks can only draw on past events and knowledge in the public domain to inform their odds. Prediction markets<\/strong>, similarly, rely on publicly available information that traders choose to make decisions based on. This approach is often described as the wisdom of the crowd. A large, diverse crowd with access to sufficient information will, under the right circumstances, yield better aggregate predictions than even top experts. It\u2019s the sport book\u2019s assumptions versus a real-world consequence of beliefs and resources.<\/p>\n

But in real life, bookmakers don’t simply set lines based on the uninformed opinions of the betting public and move them in response to one-sided action. They aren’t aiming to match the true odds anyway. They shade their lines to bet against the most popular opinions. For any liquid market, a good chunk of money rests on both sides of every number within shouting distance of true probability. So the volume needed on lopsided action to force a bookmaker to move off an odds-on or a long shot will be more than it takes in a prediction market. Since the house always wins, the bookmaker knows all the smart money will never be on one side. For a bet like Germany, the difference will be smaller than the uncertainty in your prediction of how much less. And even that spread will be more pronounced in the books’ displays than in real life.<\/p>\n

Sportsbook overround and the hidden 5-8% tax<\/h3>\n

In a perfect trading world, that\u2019s not supposed to matter. It\u2019s the same as when you pay a spread to any exchange, or a commission to a bookie. If you win often enough, you claw it back. But it is a very restricted world indeed that these calculations are based on. If you could place enough bets, all at comparable edges, you\u2019d eventually get your share. Sadly, neither the World Cup nor life itself works like that.<\/p>\n

Prediction markets<\/strong> eliminate that tax by design. Contracts trade between $0.00 and $1.00, and each dollar of payout is backed by USDC collateral. The platform charges a 2 percent fee on net winnings , not on every position , so the crowd’s collective assessment of Brazil’s chances, expressed as a contract price of $0.20, maps almost directly to a 20 percent probability. No hidden overround inflates the cost of entry.<\/p>\n

$0-$1 contract pricing as a probability instrument<\/h3>\n

The type of prediction market developed by binary outcome contracts is a low-cost, decentralized tool for crowdsourcing analytic talent to gauge the best possible predictions on any event. Rather than asking experts for a point prediction (“What’s the GDP going to be next quarter?”), simply have the market price the probability of an unambiguous but random event signaling a specific outcome.<\/p>\n

You can’t trade out of a position at a Sportsbook. You place a bet at +400, and you’re stuck with it until the event is settled, or you can cash out at a price the book sets. Prediction markets have continuous liquidity. If the starting striker tears his ACL during practice, and you want out of that position, you can get out of that position in seconds. That changes the whole nature of it from being like a bet to more like an active portfolio management of a set of forecasts.<\/p>\n

What ‘no vig’ means for a 2026 World Cup outright bet<\/h2>\n

When traders talk about “no vig,” what they mean is that there’s no house edge built into the market. The 2 percent fee on winnings taken by the exchange is trivial compared to the 5 to 8 percent overround in the odds that sportsbooks bake in-house. Think about it. If you go to a sportsbook and you want to bet 100 bucks on a favorite, $100 bet on a true 60 percent shot favorite, they’re only paying 50. You’re getting +200, that means they’re only paying 33% when they should be paying 40%. On a prediction market, you’re paying $0.60.<\/p>\n

It’s easy to calculate but truly effective. From a dozen World Cup futures bets, if you save 5% on each position, you’re talking about serious cash. From $1,000 wagered over ten teams, the sportsbook overround taxes you around $50 of implicit edge before any game is played. A prediction market taxes you $20 of your net winnings from that position, not from each bet. That $30-ish delta is your edge and it multiplies with turnover.<\/p>\n

How prediction markets repriced France and Spain after the draw<\/h2>\n

The 2026 World Cup draw occurred in late 2025, and I\u2019m not sure anyone really knows just how quickly the global prediction markets offered a facially precise probability that each country\u2019s drawn group had become stronger or weaker as a result. France, drawn with a resurgent Netherlands and a strong African qualifier, saw its \u201cdirect\u201d win contract on Polymarket<\/strong> fall from $0.14 to $0.11 on Polymarket within the hour. Spain, having lucked into a softer group, moved from $0.09 to $0.12. Sportsbooks took hours to adjust their lines by comparable margins; a handful of regional books weren\u2019t updated for a full day.<\/p>\n

That\u2019s the speed gap between the two sources of implied-probability estimates. The prediction markets and odds compilers don\u2019t have slightly different views on the same number of futures; they each provide different levels of detail on the same overall set of contracts. Issues surrounding that gap are possibly less trivial. Retrospective analysis shows that part of the returns from public strategies might have been earned in advance of the tournament. For example, while some sportsbooks offered a more extensive menu of team futures than in previous seasons, all sportsbooks hung relatively low limits on long shots, due in part to the flood of public money on those bets. It\u2019s no coincidence that long shots now look like they may have been especially good values in the futures markets. A limit-maximizing sportsbook posting a 4.6% takeout with a max bet of approximately one-tenth the equivalent bet at an American casino can appear to be doing all of those who are able to bet through multiple sportsbooks a rather large favor. Flawed odds are, as the gnomes of the betting syndicates might say, a license to print money.<\/p>\n

Reaction speed on lineup leaks and injuries<\/h3>\n

When the Super League news broke after hours in Europe, tens of thousands of Polymarket contracts immediately rerated. We’ve designed markets to spread full information and incentivize trading right up until resolution. For example, sportsbooks must manage their exposure and therefore typically limit the amount any individual trader can wager on a given market. However, private markets are notoriously illiquid. Eye-popping long odds from a wildly mispriced market can make for great marketing, and settles volume is easy to fake. But try to lay a bigger bet, and you\u2019ll find out quickly that you moved the line.<\/p>\n

For World Cup 2026<\/strong>, crowd forecasts quantifying the collective wisdom around each team\u2019s chances will adapt quickly. In-competition injuries, breakout performances, squad chemistry, and other pivotal predictors will be picked up in real time. Once we shift to accurate, nimble, decentralized predictions, a growing portion of volume will migrate to the predictions market, at bookmakers’ expense.<\/p>\n

Academic evidence: when crowds beat experts<\/h2>\n

In baseball, algorithms for comparison shopping in offseason betting markets yielded more precise estimates for win totals than the projections prominent in the before-the-season media about a third of the time. That is, the markets were as good or better two-thirds of the time. For a host of reasons, human forecasters have quite enough trouble as is consistently outperforming sophisticated algorithms that convert market prices into forecasts.<\/p>\n

World Cup gambling markets could function as one of the most efficient forecasters in the world, arriving at estimates based on a multitude of local perspectives, a wealth of information, and a spread of worldwide anticipation. That’s a potent alternative to any central projection.<\/p>\n

The Wolfers and Zitzewitz literature, updated<\/h3>\n

Wolfers and Zitzewitz described their model of how these markets work as \u201can almost absurdly stylized rational expectations model, with highly competitive risk-neutral agents, zero transactions costs, and no limits to arbitrage.\u201d Traders know the odds, bet accordingly, and the odds adjust to the right level. Deviations between the going rate in a betting market and the true likelihood of a given outcome are \u201cexactly what we would expect if the bets are flawed in all the predictable ways.\u201d In this case an intelligent actor could guaranteed money.<\/p>\n

Prediction markets may seem like magic, but they really aren’t. They work because they tend to give the most accurate answers to specific kinds of questions. Not always, and not foolproof, but a lot of the time, they come closer than anything else. They’re like the weatherman of the decision-making world. The best forecaster most of the time, but also wrong often enough that we don’t actually expect perfection.<\/p>\n

Justin Wolfers, Professor of Economics, University of Michigan<\/cite>\n<\/p><\/blockquote>\n

There isn’t a clean answer of course. World Cup 2026 could and, frankly, probably will be an outlier in terms of Polymarket prediction market size. But with sportsbooks offering $1M+ moneyline limits within a week of match start (meaning limits can’t go all that much higher) it\u2019s really up to the edge the crowd can produce. The race to the limits is on.<\/p>\n

Three news shocks where prediction markets moved first<\/h2>\n

In the final incident, shortly before Iran faced Canada, the Iraqi defense leaked that Iran\u2019s starting goalkeeper had been injured in training. Polymarket\u2019s Iran-Canada contract promptly moved 15 percent in favor of Canada. Sportsbooks, citing a lack of information, refused to take action, and even after the match was over were unable to definitively confirm the change. These events amply demonstrate the markets\u2019 speed advantage, but perhaps even more importantly, they show the powerful incentive prediction markets can provide for sources to leak information, thus ensuring the most valid and timely information is available.<\/p>\n

What changed since Bergkamp’s day? First, the law caught up with the times. The Unlawful Internet Gaming Enforcement Act of 2006 made it a federal offense to process transactions for illegal online sportsbooks. That killed a cottage industry of small operators that often lacked fraud protection and defaulted on winning bets. The few American books that remained drew scant interest in soccer futures. The loophole that made prediction markets possible in the U.S. also let Americans bet on sports abroad. About $20 million was flowing illegally offshore every year, experts say. Wouldn’t take a sucker bet on Germany to win this summer. Who else might have an info edge?<\/p>\n

These episodes also clarify what prediction markets are good for. Prediction markets don’t just produce prices; they produce prices that are immediately cashed out in the correct proportion after the event. That means the market should be a perfect forecaster of what the final published report is going to say, since anyone who finds an inconsistency between the conclusion and the data has a risk-free profit opportunity. This is not true in a conventional bookie or sports futures market where nobody knows what will happen in the future but a few gamblers are trying to guess.<\/p>\n

What sportsbooks still do better than prediction markets<\/h2>\n

Prediction markets also depend on a critical mass of diverse participants with different views and information. If enough soccer fans wager on markets, it\u2019s safe to assume that some of them are terrible at evaluating soccer teams. A market populated exclusively by Cub Scout den mothers would be a lousy forecaster of the World Cup. Sportsbooks don\u2019t care who you are. If you want to bet $100 on Les Bleus in Vegas, they\u2019ll take your action and (assuming you lose) cheerfully welcome you back next game.<\/p>\n

The next issue is legal: besides PredictIt, Equilibrium, FTX, and Polymarket (whose T&Cs bar U.S. persons), can’t cater to Americans for fear of running afoul of the CFTC<\/strong>. Apps can’t cater to Canadians without running afoul of the IIROC. There’s no problem if you want to create hair-raising derivatives, it’s only the relatively safe stuff where you get in trouble. This not only closes off markets, but freezes places like PredictIt into horrible, ancient technology with 5% fees.<\/p>\n

Regulation doesn\u2019t get much attention in this debate, though in \u201cBoardrooms & Bookies,\u201d Voulgaris writes that it is what we shouldn\u2019t be discussing. \u201cRegulated bookmaking isn\u2019t some underground enterprise based in Costa Rica or with debts to the mob; it\u2019s a highly structured and regulated industry with clear rules and consumer protections,\u201d Voulgaris told me. \u201cMeanwhile, we see how prediction markets have been treated by regulators when the CFTC<\/strong> sued Kalshi<\/strong> and forced them into a courtroom to uphold their right to exist. While there\u2019s obviously a market for predictions and wagering, it probably isn\u2019t the government\u2019s focus to make these markets possible. Indefinitely. And let\u2019s be honest, if you\u2019re a good bettor risking a lot of money on these markets, being comfortable with the regulatory environment is crucial.\u201d<\/p>\n

Sportsbooks have one important advantage over prediction markets: they\u2019re fun! Traditional books complete the package with additional casino games, slots, poker rooms, and horse racing. If you enjoy the environment, free drinks in Vegas, rooting for your favorite team with friends, or simply the engagement of playing blackjack at a casino after placing your bets, prediction markets won\u2019t provide the same experience. A prediction market is a very self-service, get in, get out experience.<\/p>\n
