Resolution Criteria This market will resolve based on official statements from law enforcement, court documents, or credible reports that definitively establish the motives behind Brian Thompson's assassination. Multiple answers may resolve YES if multiple motives are established.

• "Radical Leftism" resolves YES if evidence shows the attack was primarily motivated by far-left ideology or anti-capitalist extremism

• "Personal tragedy" resolves YES if the assassin or their family member experienced documented harm from UnitedHealthcare policies/decisions that motivated the attack

• "Business" resolves YES if the motive was related to business dealings, corporate rivalry, or financial disputes, either with respect to Brian Thompson personally or UnitedHealthcare

• "Mental health crisis" resolves YES if official reports indicate the attacker's primary motivation was related to mental illness or psychosis

• "Targeted hit/contract killing" resolves YES if evidence shows the assassination was a paid hit or professionally orchestrated murder

• "Personal conflict" resolves YES if the motive stemmed from personal grievances between the assassin and Thompson

If no compelling evidence exists that a motive was a substantial factor in the assassin's actions by December 31st 2025, or by the conclusion of a trial if such occurs and is likely to present novel information as to motives, remaining outstanding motives will be resolved NO.

Please feel empowered to add your own options.

Possible clarification from creator (AI generated):

• For the Personal tragedy option, the tragedy must have been experienced directly by the assassin themselves, not by someone who hired them

• If the assassin was hired by someone who experienced a personal tragedy, this would resolve as Targeted hit/contract killing only

• If the assassin both suffered a personal tragedy AND was being paid, both options could resolve YES if there is evidence for both motives

• Update 2024-10-12 (PST) (AI summary of creator comment): - For the Personal tragedy option, the assessment will be based on the assassin's subjective experience and perception of events, not an objective measure of harm

  • Normal bureaucratic processes that caused significant distress to the assassin can qualify as a personal tragedy

  • If the wrongful denial of claims option resolves YES, the Personal tragedy option will automatically resolve YES

• Update 2024-10-12 (PST): - The option 'An attempt to change the incentive structure' will resolve YES if there is:

  • Direct evidence of intent to alter incentives for healthcare CEOs

  • OR substantial evidence of intent to influence CEO behavior through fear or threats to 'business as usual' (AI summary of creator comment)

• Update 2024-10-12 (PST) (AI summary of creator comment): - For the Mental health crisis option, an insanity plea would resolve YES

  • A mental health crisis does not need to be the primary motivation - it only needs to be one of the primary motivations

• Update 2024-13-12 (PST): - Drug-induced psychosis will be considered part of the Mental health crisis option (AI summary of creator comment)

• Update 2024-13-12 (PST) (AI summary of creator comment): - Radical leftism will resolve YES if motives are based on:

  • Ideology supporting collectivization of means of production

  • Support for expropriation/redistribution of wealth

  • Extra-legal revolution for leftward economic shift

  • Membership in DSA or explicit agreement with DSA principles

  • Radical leftism will resolve NO if motives are based on:

  • Support for European-style socialized healthcare

  • General social democracy or welfarism

  • Belief that corporations should be socially beneficial

• Update 2024-13-12 (PST) (AI summary of creator comment): - For the Radical Leftism option, advocating for stakeholder capitalism, corporate regulation, or corporate social responsibility will not qualify as radical leftist motives

  • The use of radical/extreme tactics (like assassination) does not automatically make the underlying political beliefs radical for resolution purposes

• Update 2024-17-12 (PST) (AI summary of creator comment): - For the Mental health crisis option, the resolution will use a broader definition of acute mental health as a motive, rather than the technical/clinical definition of a mental health crisis

  • The assessment will not be strictly limited to official clinical criteria for what constitutes a mental health crisis

• Update 2024-18-12 (PST) (AI summary of creator comment): - The Mental health crisis option has been renamed to Mental illness to better reflect that mental health related motives do not need to be concentrated in an acute period

  • Mental health issues only need to be one of the contributing factors, not necessarily the primary motivation

  • A clinical/technical definition of mental health crisis will not be used for resolution

• Update 2024-18-12 (PST) (AI summary of creator comment): - For the Mental illness option (formerly Mental health crisis), the resolution will use a broader definition similar to severe persistent mental illness, rather than requiring an acute crisis period

  • The assessment will not be strictly limited to clinical/technical definitions

  • Mental health issues only need to be one of the primary motivations, not necessarily the sole primary motivation

• Update 2024-19-12 (PST) (AI summary of creator comment): - For the Mental illness option, resolution will be based on a holistic and qualitative judgment by the creator

  • Appeals can be made to moderators if traders strongly disagree with the creator's resolution
