Yves right here. Rajiv Sethi focuses on the chance that PredictIt must wind down operations, and the messiness and gaming alternatives that can outcome from having to shut out contracts that expire after PredictIt ends operations. He mentions solely in passing that this occasion would additionally shutter the final vital on-line election prediction market. There’s quite a lot of enthusiasm for prediction markets as soothsayers, however that could be as a lot because of the disastrous state of polls because the supposed virtues of prediction markets (pollsters have quite a lot of issue getting anybody to reply questions, and their calling lists are skewed in the direction of landlines, as in previous farts).
Prediction markets work greatest after they characterize the citizens nicely. The rationale the Brexit betting markets have been so fallacious (they predicted a Stay win by 6 factors the evening earlier than the vote) is that in playing, the “votes” are weighted by {dollars}, or right here kilos, as the whole wagered for both sides. However the precise variety of bettors favoring Brexit was a lot bigger than Stay bettors!
As Barry Ritholtz wrote in 2008:
Through the years, I’ve been vital of prediction and futures markets. Specifically, the precise methods sure events misuse them (i.e., politics).
Nevertheless, I’m an enormous believer that markets can generate precious financial and investing information that may be fairly useful when dealt with appropriately…
In every of those circumstances, we’re counting on markets which might be deep, various and buying and selling in greenback volumes measured in trillions. That is a part of my criticism about future markets: They’re skinny, buying and selling volumes are anemic, the greenback quantities in danger are pitifully small. Thus, these markets are topic to failure at occasions.
Certainly, the excuse making for the failure of the futures market started virtually as quickly because the New Hampshire major ended (see Why the On-line Prediction Markets Blew New Hampshire, Prediction markets are forecasting instruments of comfort that feed on superior indicators, and so forth.)
None of those actually checked out what makes futures markets work, how they will fail, and what their strengths and weaknesses are. This morning, I wish to delve into some the issues these markets can have, why they fail, and what worth they do supply.
First, Let’s begin by reviewing among the extra spectacular prediction market failures:
• Iowa Major 2004 (Howard Dean vs everybody else)
• 2006 GOP Senate Retention
• New Hampshire Major 2008 (Obama vs Hillary)
Within the space of politics, I’m in settlement with Dan Gross, who wrote “these are much less futures markets than immediate-past markets.” In different phrases, bettors basically combination polling information that’s already out — somewhat than forecasting the unknown future.
Relating to politics, its not as if the Iowa digital market or Intrade gamblers have any particular perception or inside information. They don’t “know” something — as people or collectively — that the remainder of the general public (insiders included) don’t already know. They’re all studying the identical newspapers, blogs, polls, and so forth., and responding to no matter broad narrative occurs to be popping out that day or week. They reply simply as some other focus group would, off of the identical data the citizens has.
I typically consider the political futures markets as a spotlight group unto themselves. Right here’s the place issues get actually fascinating: When the group is one thing much less consultant of the goal market, they get it fallacious with alarming frequency. Certainly, the nearer the merchants are as a bunch to the goal choice makers/voters, the higher their monitor report.

The prediction market PredictIt has been working beneath a no-action letter from the CFTC since 2014. This permission has now been withdrawn, and the alternate has been ordered to liquidate all open positions by February 15 of subsequent 12 months:
The Commodity Futures Buying and selling Fee’s Division of Market Oversight (DMO) at the moment introduced it’s withdrawing CFTC Letter No. 14-130 efficient instantly. When DMO issued the letter on October 29, 2014, it took a no-action place with respect to the operation of a not-for-profit marketplace for sure occasion contracts and the providing of such contracts to U.S. individuals by Victoria College of Wellington, New Zealand… DMO has decided that Victoria College has not operated its market in compliance with the phrases of the letter and consequently has withdrawn it… all associated and remaining listed contracts and positions comprising all related open curiosity in such market must be closed out and/or liquidated no later than 11:59 p.m. (EDT) on February 15, 2023.
Permission to function was primarily based on the satisfaction of 9 situations, a number of of which the CFTC alleges have been violated. It’s not clear what the exact nature of the violation was, however the situations for continued operation have been the next:
DMO granted the aid primarily based upon the representations of the College that the proposed occasion contract market would:
- be small-scale and not-for-profit;
- be operated for educational and analysis functions solely;
- be overseen by college on the College, with out receipt of separate compensation;
- supply occasion contracts consisting of two submarkets for binary possibility contracts regarding political election outcomes and financial indicators;
- be restricted to five,000 merchants per contract, with an $850 funding restrict per participant in any contract;
- not supply brokerage providers or cost commissions to members;
- make the most of a third-party service supplier to carry out know-your-customer (“KYC”) due diligence on its members;
- solely cost these charges essential to cowl the achievement of the KYC course of, regulatory compliance, and primary bills to function the proposed occasion contract market; and
- restrict promoting to media retailers the place there’s a excessive chance of reaching these desirous about the subject material of its occasion contracts, supplied that such promoting prominently discloses that the platform is unregulated, experimental, and being operated for educational functions.
PredictIt maintains that it violated none of those situations. In an electronic mail to merchants, the alternate argues that it “disagrees with the Fee’s choice and maintains that each one lively markets should not solely throughout the phrases of the No-Motion letter however are additionally in keeping with Fee interpretations conveyed to us over the previous eight years.”
If the alternate actually is to close down in a number of months, an vital unresolved query considerations the decision of markets that reference occasions past February 2023. There are numerous of those, with very lively buying and selling within the presidential nomination markets for the 2 main events, and the end result of the 2024 presidential election.
For instance, think about the marketplace for the Democratic nomination, the place Gavin Newsom (for some cause) is buying and selling at 20 cents to the greenback, behind Joe Biden however forward of Kamala Harris. The market is successfully assigning to him a chance of one-in-five of being the nominee. Right here is the historical past of costs on this contract over the previous 90 days:
There was an enormous spike in buying and selling on June 14, with about 40,000 contracts altering arms at a worth of 5 cents apiece. Somebody who purchased 10,000 contracts on that date paid $500, and these contracts at the moment are price $2,000. However because the occasion won’t be resolved by February 2023, what’s to turn out to be of this place?
The alternate must work out a way of liquidating these contracts forward of the listed termination date. One risk that may be dominated out instantly is the reversal of all transactions in such markets. Such reversal would basically undo all trades, so the (hypothetical) dealer in query would get a $500 refund and the contracts would vanish from their account. This isn’t potential—for instance, this dealer might nicely have offered off all contracts at varied costs within the interim, withdrawn all funds, and closed out their account.
So what might the alternate do? It might halt buying and selling in some unspecified time in the future (with or with out discover) and liquidate all contracts on the worth of final commerce. However there are two issues with this. It might end in folks making an attempt to control the value of the final commerce in ways in which would end in extra favorable decision for them. And it might end in some very unusual costs—for instance the sum of all contracts within the nomination markets might significantly exceed 100 cents to the greenback. This occurs anyway every now and then, because of the payment construction on the alternate, however the impact can be amplified dramatically as folks attempt to recreation the system of their favor. The same old arbitrage-based mechanisms that hold costs roughly in keeping with possibilities can be weakened since there isn’t any assure that eventual decision will fulfill the legal guidelines of likelihood.
So there’s an actual drawback right here, and it’s not clear how the alternate will cope with it. Given the uncertainty, I count on that there shall be a surge of withdrawals, and folks with notional income will liquidate now and money out. However others would possibly see a chance within the midst of frantic and chaotic buying and selling. When Intrade shut down all of a sudden 9 years in the past, accounts have been frozen and withdrawals halted. I count on that this time the closure shall be extra orderly.
However right here the factor—with PredictIt gone there shall be no complete market-based forecasting system for elections in the US. Kalshi is CFTC authorized and controlled however hasn’t but entered this area. The pioneering Iowa Digital Marketsare nonetheless in operation however with very restricted quantity and protection. Mannequin-based forecasters similar to FiveThirtyEight are round, after all, however it will likely be a bit more durable to judge their efficiency relative to markets. So if there’s an excellent rationale for shutting down this alternate, I hope the CFTC will make it specific in some unspecified time in the future.
In an earlier publish, I made the purpose that prediction markets are uncommon amongst on-line platforms in facilitating viewpoint range, by creating sturdy incentives for individuals who disagree with one another to work together:
Individuals actively search data that largely confirms their current beliefs, and social media platforms accommodate and intensify this demand. Prediction markets play an fascinating and traditional position on this atmosphere. They encourage folks with opposing worldviews to work together with one another in nameless, credible, and non-violent methods. In a way, they’re the other of echo chambers. A market with homogeneous beliefs would haven’t any buying and selling quantity, or would entice these with totally different opinions who’re drawn by what they understand to be mispriced contracts.
Whereas most on-line platforms facilitate and deepen ideological segregation, prediction markets do precisely the other. They supply financial reinforcement to those that get it proper, and pressure others to query their assumptions and predispositions. Whereas greatest often known as mechanisms for producing forecasts by way of the knowledge of crowds, additionally they carry opposing worldviews into direct and consequential contact with one another. This can be a helpful perform in an more and more segregated digital ecosystem.
In reality, there’s a actual sense during which PredictIt gave us advance warning about January 6. Virtually a month after the 2020 election, after a decisive variety of states had licensed their vote totals, the alternate was nonetheless giving the incumbent a one-in-eight probability of successful reelection. A typical interpretation on the time was that markets had gone haywire. The reality is that there was data on the market, unseen by most of us, that there was a serious shock in retailer.
