As the battle between the prediction markets and the gambling industry intensifies, two professional papers from opposing camps this month may have prematurely revealed the direction of this regulatory game. Former Carl Xi Chief Regulatory Officer and current Senior Advisor to the Chairman of the U.S. Securities and Exchange Commission, Eli Mishori, published a working paper titled "Information Asymmetry and Event Integrity in Prediction Markets: A Framework for the CFTC," systematically categorizing the information advantage in prediction market transactions into four types, advocating for distinctly different regulatory treatments for different types of non-public information. Subsequently, Jon Russell, a long-time executive in the sports betting industry at William Hill, Ladbrokes, and Betway, responded with a paper titled "From Classification to Detection" — he stated that he did not intend to overthrow Mishori's framework, but directly pointed out that this meticulously constructed classification system is almost useless at the enforcement level. Russell's original words were quite harsh: The classification system can only tell you what to look for, not how to find it.
Mishori's Four-Tier Information Advantage Framework: From Theft to Skill
In his paper, Mishori constructed a gradient of information advantage from explicitly prohibited to explicitly allowed. The top red line is the use of stolen or illegally obtained non-public information, which should be explicitly prohibited, and any exchange that allows such transactions is rewarding crime and punishing law-abiding traders. The bottom green area is skill-based information obtained through the trader's own analysis or research, which should be explicitly allowed. The real challenge lies in the two gray areas in between.
The first is non-public proprietary information, i.e., information held by traders directly involved in the underlying events. Mishori argues that such transactions should generally be allowed without additional disclosure obligations, for a straightforward reason — the architecture of financial markets inherently includes traders who hold their own non-public information, just like corporate executives trading their own stocks, which is not an alien distortion of the market but a part of its structure. The second is non-public third-party information, i.e., event information obtained indirectly through relationships. Mishori believes that such transactions can be allowed but must be accompanied by sufficient market-level disclosure to make participants aware of the potential presence of relationship-based information advantage counterparts in the market before entering.
Mishori separated event manipulation from information issues. He believes that personnel-based prohibitions — prohibiting athletes, coaches, referees, election officials, etc., from trading due to their ability to manipulate event outcomes — are highly effective in combating result manipulation, but this should be categorized separately from information asymmetry issues. Using this framework to analyze the recent case of an American soldier arrested for insider trading related to the alleged ousting of Venezuelan President Maduro, the soldier's use of non-public proprietary information for trading is legal within the framework, but given his participation in the actual raid and his ability to manipulate event outcomes, he should be excluded from trading based on personnel prohibition principles.
Russell's Rebuttal: Classification Cannot Replace Detection Infrastructure
Russell's response precisely hit the weakest link in Mishori's framework. He used a specific scenario to illustrate the problem: employees of a game show may have non-public information about which contestant will be eliminated, but employees of a third-party telephone company responsible for compiling voting data might also have this information, and these two sources of information are almost impossible to associate and identify in the monitoring system. The market can only see price fluctuations and abnormal order flow patterns; non-public status is not something that can be directly observed by the monitoring system, only inferred from imperfect deductions — inferring what the market should know at a certain moment and whether a particular bet exceeds this knowledge boundary.
Russell's deeper criticism points to a recurring cycle within the prediction market industry. Twenty years ago, the regulated sports betting market also experienced shocks from information asymmetry, insider trading, and integrity risks. Today's prediction markets are essentially re-walking the path of sports betting, which had already solved these problems through trial and error twenty years ago. From data subscription sources, alert logic to information sharing agreements with event stakeholders, and investigation procedures, this set of detection infrastructure that makes rules executable took twenty years to build in the sports betting field, and in the current debate on prediction market policies, these are almost completely absent.
PASA Official Website continues to track the evolution of global prediction market regulatory frameworks and technical standards, noting that the core tension in this academic debate lies not only in who can provide more accurate information classification but also in who has the implementable detection capability. As CFTC Chairman Michael Selig initiates the process of formulating rules for prediction markets, this institution, currently with only one sitting commissioner, is facing comprehensive monitoring challenges from finance, politics, sports, and popular culture. Russell's concluding remarks are thought-provoking: Mishori has constructed a legal framework, but the layer of detection infrastructure that makes this framework executable is the most urgently needed puzzle piece in the prediction market industry right now.
