The historical baseline for assassination attempts against Donald Trump has shifted from sporadic security breaches to frequent, lethal engagements. On July 13, 2024, Thomas Matthew Crooks wounded Trump at a rally in Butler, PA, the first such event for a major candidate in decades. This was quickly followed by a second attempt on September 15, 2024, involving Ryan Wesley Routh at a Florida golf course. By 2026, the tempo increased significantly. On April 25, 2026, Cole Tomas Allen fired shots at the White House Correspondents’ Dinner, and on May 23, 2026, Nasire Best opened fire at a White House checkpoint. Historically, presidential security threats often cluster around periods of intense domestic political division or foreign conflict, both of which are present in the 2026 landscape due to the midterm elections and the outbreak of war with Iran in February 2026. These events have moved the risk profile from a ‘low-probability, high-impact’ event to a recurring security challenge characterized by DOJ-level indictments for ‘Attempted Assassination.’
My analysis of the timeline for the next assassination attempt against Donald Trump is driven by an unprecedented escalation in both the frequency and characterization of security incidents between 2024 and 2026. Prior to mid-2024, such attempts were statistically rare. However, the period from July 2024 to May 2026 has seen at least four incidents officially or legally characterized as assassination attempts (Butler, PA; West Palm Beach; Washington Hilton; and the White House checkpoint). This represents a base rate of approximately two qualifying attempts per year.
The prediction of 19th September 2027 as the median date balances three distinct risk phases. First, a high-intensity ‘near-term’ risk exists through the summer of 2026. This is fueled by copycat dynamics following the May 23, 2026 shooting and a series of high-exposure public events, most notably the ‘UFC Freedom 250’ on the White House lawn on June 14, 2026. This event, involving 4,000 guests in a temporary outdoor structure, contradicts typical security protocols and provides a concentrated window of opportunity.
Second, a ‘medium-term’ risk persists through the 2026 midterm elections and into 2027. This phase is heavily influenced by geopolitical factors, specifically the 2026 Iran war which began in February 2026. The IRGC’s documented history of murder-for-hire plots (e.g., Asif Merchant and Farhad Shakeri) suggests that state-sponsored attempts will continue as long as regional conflict remains active.
Third, a ‘long-term’ background hazard accounts for the remainder of Trump’s term. While security typically hardens following successful or near-successful attempts, the extreme political polarization in the U.S. ensures a steady stream of lone-actor threats. My weighting considers that while security measures (like the proposed $1 billion White House ballroom) will eventually reduce vulnerability, the arrival rate of threats remains high. The median date reflects the point where the cumulative probability of these multiple threat vectors (state-sponsored, lone-actor, and copycat) reaches 50%. The forecast acknowledges that while another attempt is more likely than not, the Secret Service’s elevated protective posture and the disruption of plots (like the March 2026 conviction of Asif Merchant) provide a significant counter-force that prevents these incidents from occurring even more frequently.
Will there be an overt physical incident against Trump between 2026-05-28 and 2026-08-12 that authorities or major outlets call an “assassination attempt”? Forecasters agree the baseline historical rate for presidential assassination attempts is very low, but everyone raises the near-term risk because Trump experienced two official attempts in 2024 and DOJ charged an April 2026 case as an “attempt to assassinate,” showing clustering is possible. They stress the question requires both an overt act and official or broad media characterization, so many nearby shootings, perimeter breaches, and threats (which are elevated) will not qualify. The panel points to concentrated hazard spikes around highly public, pre-announced Freedom 250 events—especially the late-June/July National Mall dates and the July 4 celebration—while noting major security hardening after the April incident likely reduces exposure for controlled venues. Most forecasters place substantial probability on no qualifying event by Aug. 12 but assign a meaningful minority probability (~14–15%) to a qualifying attempt, with remaining risk spread across the window. They recommend watching DOJ/FBI/Secret Service language and major outlets for official classification within 14 days, and monitoring whether Trump attends less-controlled events (hotels, golf courses, route details) which elevate vulnerability.
Forecast: Probability distribution:
We are forecasting the first post-2026-05-27 incident that is officially (or by 3+ specified major outlets) characterized as an “assassination attempt/attempted assassination” against Donald J. Trump. This is a high bar: many security incidents, threats, or perimeter breaches will not qualify unless authorities/news explicitly use the required terminology within the stated timeframe.
Across the team forecasts, the key disagreement is the in-window probability (by 2026-08-12). Forecasters 1, 2, and 4 implicitly place F(2026-08-12) around ~25–40%; Forecaster 3’s written reasoning aligns with a large open-tail but their percentile table mistakenly piles mass at the upper bound (which would represent resolution on the deadline date, not “after”).
Using the team’s base-rate logic (multiple prior officially-termed attempts over ~2 years) gives a rough Poisson-style expectation of ~0.3–0.4 attempts over a 76-day window, i.e. ~25–35% chance in-window. I adjust slightly upward within that band for clustering/copycat risk and Trump’s likely summer public exposure, but downward for (i) strong protective adaptation and (ii) the strict “must be called an assassination attempt” resolution filter. Net: I center on ~30–40% probability of a qualifying incident by 2026-08-12, with the remainder in the open-after tail.
Accordingly, I place p40 just past the upper bound (encoding substantial open-tail mass), and spread the post-bound percentiles out to 2026-08-31 (the max usable past-upper date) without stacking at the deadline.
An amateur forecast is likely to (a) treat any serious security incident as an “assassination attempt,” overstating in-window probability, and/or (b) anchor to the administrative deadline by stacking percentiles at 2026-08-12 (misrepresenting “after the window” as “exactly on the deadline”). This forecast explicitly accounts for the question’s narrow characterization criterion and represents “no qualifying incident by the deadline” correctly by placing much of the distribution strictly past 2026-08-12. Confidence in improvement is moderate: the event is inherently hard to forecast, but proper handling of the resolution filter and open-tail semantics is a clear advantage.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the main reasoning is that Trump faces an elevated short-term threat environment compared with historical norms, but another qualifying assassination attempt is still far from certain.
The collective view is that another assassination attempt is plausible but not dominant in the near term. The recent spike in incidents and Trump’s public schedule push risk upward, but improved protection and the short time window keep the probability well below certainty.
— Iteration 2 — Across the forecasts, the reasoning is driven by a few recurring themes:
The collective view is that another attempt is plausible but still not the modal outcome in the near term. The strongest arguments for an earlier event are the recent pattern of attempts and upcoming public exposure; the strongest arguments against are the historically low base rate, the difficulty of predicting lone-actor violence, and the possibility that security improvements prevent an incident.
— Iteration 3 — Across the forecasts, the main reasoning pattern is that the risk is treated as elevated relative to a normal baseline, but still constrained by the rarity of a qualifying assassination attempt and by tighter security.
The unified view is that recent incidents and Trump’s 2026 schedule increase near-term risk, but improved protection and the rarity/definition threshold for a qualifying attempt keep the forecast highly uncertain and heavily skewed with a long tail into future years. If another attempt occurs soon, the likeliest timing is around a major summer 2026 public event; otherwise, the event may simply not occur within the near-term resolution window.
The rationales broadly agree on a forecasting tension between an extraordinarily elevated physical threat environment and the strict definitional requirements necessary for an incident to officially qualify.
Elevated Threat Profile and Catalysts Forecasters note that while historical base rates for presidential assassination attempts are exceptionally low, the recent frequency of attacks against Donald Trump represents a significant anomaly. This elevated risk is compounded by a psychological “contagion effect” stemming from a cluster of highly publicized security incidents in early 2026. Furthermore, the immediate forecast window aligns with severe risk multipliers, including polarizing political flashpoints (such as impending Supreme Court rulings and midterm elections) and an unusually exposed summer schedule featuring massive outdoor events like the July 4th Semiquincentennial and “Freedom 250” celebrations. Active intelligence regarding state-sponsored plots and domestic extremism further sustains this high baseline hazard.
Security Enhancements and Definitional Constraints Despite the heightened threat, the rationales emphasize that the strict resolution criteria act as a strong mitigating factor. To be officially categorized as an “assassination attempt” by authorities or major media, an attacker must typically commit an “overt act” or “substantial step” demonstrating specific intent. In response to recent attacks, the Secret Service has drastically fortified protective perimeters with advanced countermeasures and militarized deployments. Forecasters argue that these upgraded defenses are highly likely to intercept hostile actors before they can cross the legal threshold of an overt act. Consequently, while general security breaches or thwarted plots remain highly likely, the stringent definitional threshold significantly suppresses the expected rate of officially recognized attempts.

The research compiles documented incidents from July 2024 through May 24, 2026, noting five serious security incidents involving Donald Trump: the July 13, 2024 Butler, PA shooting (shooter Thomas Matthew Crooks killed by Secret Service; FBI found he acted alone), a September 15, 2024 arrest of Ryan Wesley Routh near Trump’s golf club, an April 25, 2026 breach and shooting at the Hilton during the White House Correspondents’ Dinner (Cole Thomas Allen), an unexplained armed shooting near the White House on May 5, 2026, and the May 24, 2026 May 24 incident (Nasser Best firing from a bag near a White House barrier and being neutralized). From July 2024–May 2026 (~23 months) the research counts 4–5 serious incidents, equivalent to ~2.6 incidents per year (average inter-incident interval ~4.6 months) with recent clustering (April and May 2026) and the most recent incident occurring four days before the forecasting window began.
The research identifies primary threat vectors and risk factors: transnational plots linked to Iran (e.g., the conviction of Asif Merchant in March 2026), domestic lone actors with mental-health issues, and security vulnerabilities around large events and perimeter failures (noted concerns about the 2026 World Cup, G7 summit timing, and hotel/exterior security gaps). It reports that prediction markets had tracked assassination-related questions historically (Polymarket) but did not find active markets forecasting timing of the next attempt. The research also lays out definitional criteria for labeling an event an “assassination attempt” (official designation by Secret Service/FBI/DOJ within 14 days or by 3 of 7 major news outlets), notes that official and media classifications vary across incidents, and lists key uncertainties and data limitations (changes in security posture, incomplete public schedule of appearances, lack of active timing markets, and potential source biases).

Your forecasting window is extremely narrow—just 76 days from May 27, 2026 23:38:08 UTC to August 12, 2026 12:00:00 UTC. Critically, the most recent confirmed incident occurred just 4 days before your question opened.
2024:
2026:
From July 2024 to May 2026 (~23 months), Trump experienced 4-5 serious incidents that were officially characterized or met the threshold for assassination attempts. This translates to approximately 2.6 attempts per year or roughly one attempt every 4.6 months [1][2][3][4][9].
Polymarket tracking of Trump assassination-related questions:
September 2024 - “Fact Check: Was it an attempt on Trump?” (regarding Florida golf incident)
Volume: $86,107
Resolved: Yes (100% probability) [16]
July-August 2024 - “Fact Check: Was it a rogue actor?” (regarding Butler shooting)
Volume: $1.06 million (highest engagement)
Resolved: Yes - shooter acted alone (100% probability)
Polymarket reported 94% one-month accuracy [18]
Key Observation: While Polymarket has tracked assassination-related questions with substantial liquidity (up to $1M+), I did not find active prediction markets specifically forecasting when the next attempt will occur or probability of an attempt within your forecast window.
Your resolution criteria require official characterization as “assassination attempt” by:
Precedent: The May 24, 2026 incident was labeled by DOJ as “second attempted assassination” [9], showing official bodies are willing to use this terminology. However, not all security incidents receive this classification—the May 5 incident appears less clearly characterized [2].
This research provides you with the empirical foundation, but the forecast itself remains highly uncertain given the unprecedented frequency of recent events combined with the very narrow 76-day window immediately following a May 24 incident.
Conditioning on the question not being annulled, and treating dates after 2026-08-12T12:00:00Z as representing the censored outcome >2026-08-12T12:00:00+00:00.
(a) Time left until outcome is known.
From the opening timestamp, the incident window lasts 76 days, 12 hours, 21 minutes, 52 seconds, ending 2026-08-12T12:00:00Z. If an incident occurs at the very end of the window, the characterization rule could take up to 14 more days, so final resolution could take until about 2026-08-26T12:00:00Z.
(b) Outside view.
The broad U.S.-presidential-assassination-attempt base rate is very low, but Trump is a poor fit for that broad base rate. A more relevant Trump-specific base rate counts official/near-official attempts on 2024-07-13 in Butler, 2024-09-15 in Florida, and 2026-04-25 at the White House Correspondents’ Dinner. The FBI explicitly treated Butler as an assassination attempt, DOJ later described Routh’s Florida incident as an attempted assassination, and DOJ charged Cole Tomas Allen with attempting to assassinate President Trump for the April 2026 incident. (fbi.gov)
A crude 3-event-in-~22-month Trump-specific rate gives roughly 1.5–1.7 qualifying attempts/year, implying about 27–30% in a 76.5-day window under a Poisson model. The research assistant’s broader “4–5 serious incidents in 23 months” reference class implies about 2.6/year, or roughly 42% in this window, but that includes events that may not satisfy this question’s strict characterization rule.
(c) Inside view.
Upward updates: recent incidents are clustered; the April 2026 dinner incident was officially charged as an assassination attempt; and DOJ says an Iranian-linked operative was convicted in March 2026 after a foiled plot to murder U.S. politicians or officials, with DOJ statements naming Trump as a possible target. (justice.gov)
Downward updates: after each serious incident, protection and scrutiny should intensify; many threats or armed incidents do not meet the official “assassination attempt” threshold; and the May 23/24 White House checkpoint shooting was publicly described by AP/Secret Service as a man firing near a checkpoint, not clearly as a Trump assassination attempt under the resolution standard. (apnews.com)
(d) Outcome if nothing changed.
If the current security posture and threat-detection environment simply hold, the modal outcome is no qualifying incident before 2026-08-12T12:00:00Z, resolving as >2026-08-12T12:00:00+00:00.
(e) Outcome if the current trend continued.
If the April–May clustering continued without mean reversion, I would expect another serious incident in late June to mid-July 2026, but I only partly weight that because violent-event clusters often trigger security responses and media attention that change attacker behavior and protective protocols.
(f) Experts and markets.
I did not find a direct, liquid prediction market for “another Trump assassination attempt by August 2026.” The closest markets I found were retrospective/fact-check-style markets around prior attempts rather than forward timing markets. (polymarket.com)
Security reviews after Butler emphasized both serious past failures and subsequent reforms, so the expert/security-institution signal is mixed: the risk is real, but the protective apparatus is actively adapting. (abcnews.go.com)
(g) Unexpected low/earlier scenario.
A copycat or ideologically motivated lone actor attempts an overt attack very soon after the recent publicity, and official sources quickly characterize it as an attempted assassination.
(h) Unexpected high/later scenario.
Heightened protection and earlier interdiction convert would-be attacks into arrests, threat cases, or non-qualifying security incidents, so nothing meeting the strict wording occurs before the cutoff.
Rationale.
I anchor on the Trump-specific base rate rather than the general presidential base rate because the recent history is plainly anomalous. The narrow-window Poisson estimate from strict official attempts is around 30%, while including serious but not necessarily qualifying incidents pushes toward 40%+. I move somewhat upward from the strict base rate because of recent clustering and persistent threat signals, but not all the way to 50% because the resolution criteria are stringent and immediate post-incident security is likely elevated. My implied probability of a qualifying incident by the cutoff is about 37–38%, so the median lies after the range maximum.

(a) Time left until outcome is known: about 90 days. The event window ends at 2026-08-12T12:00:00Z, but because classification can occur up to 14 days after an incident, final resolution could require waiting until 2026-08-26T12:00:00Z. Conditioning on the question not being annulled.
(b) Outside view: The most relevant base rate is Trump-specific rather than all-presidents. Since 2024-07-13, there have been several serious attempts/incidents, with clearly qualifying attempts on 2024-07-13, 2024-09-15, and 2026-04-25, plus additional armed/gunfire incidents near Trump in 2026. The research assistant’s surfaced rate of roughly 4–5 serious incidents in about 23 months implies about 2–3 per year, or roughly a 35%–45% Poisson chance over this 76-day window. The stricter “officially characterized as assassination attempt” base rate is lower, closer to 25%–35%.
(c) Inside view: I update upward from ordinary presidential-assassination base rates because Trump is an extreme outlier: DOJ officially charged the 2026-04-25 White House Correspondents’ Dinner suspect with attempting to assassinate the president, and AP reported that the 2026-05-23 White House checkpoint shooting was the third gunfire incident near Trump in the prior month. (justice.gov) I also update upward from evidence of organized foreign plotting: DOJ said Asif Merchant, an IRGC-linked operative, was convicted in 2026-03 for a foiled plot involving political assassinations including President Trump. (justice.gov) I update downward because security posture should be unusually high after the recent incidents, and Reuters/ABC reported immediate reassessments/reviews of Trump event security after the 2026-04-25 shooting. (investing.com) I also discount incidents that are merely threats, breaches, or gunfire near protected zones but are not officially/news characterized as assassination attempts.
(d) Outcome if nothing changed: No qualifying new incident occurs, resolving as later than 2026-08-12T12:00:00Z.
(e) Outcome if the current trend continued: The recent clustering would imply a qualifying event in the first half of the window, roughly 2026-06-15 to 2026-07-15.
(f) Expectations of experts and markets: I do not have a credible liquid market price for this exact question. Expert/security commentary is mixed: the recent incidents are treated as evidence of elevated risk, but the same incidents are also prompting tighter security reviews and changes, which should reduce near-term exposure.
(g) Unexpected low outcome scenario: A lone-actor/copycat attempt is already in motion and reaches the overt-act threshold at a near-term public appearance or protected-site perimeter, leading officials or at least three specified news organizations to call it an attempted assassination within 14 days.
(h) Unexpected high outcome scenario: Security changes sharply reduce public exposure and intercept threats before an overt act occurs; future arrests are categorized as threats, plots, or security incidents rather than “attempted assassination,” so the question resolves after 2026-08-12T12:00:00Z.
Rationale: I anchor on the Trump-specific recent base rate, not on the very low historical rate for presidents overall. A simple 2–3 serious-events/year base rate gives a material but not majority probability over 76 days. I then adjust upward for the unusually recent cluster and demonstrated official willingness to use “attempted assassination” language for the 2026-04-25 incident. I adjust downward for the strict resolution criteria, immediate security hardening, and likely regression from an unusually dense cluster. My net forecast is about a 38% chance of a qualifying incident on or before 2026-08-12T12:00:00Z; dates after 2026-08-12 in the percentiles represent the right-tail/no-qualifying-incident-by-cutoff state.

I continue to condition on not annulled. Annulment is still negligible: a qualifying physical incident against Trump would almost certainly be publicly date-verifiable.
I accept the critic’s central correction: my earlier forecast still leaned too much on treating the recent Trump-specific cluster as a stable, homogeneous rate. The April 25, 2026 WHCD attack is a strong qualifying data point: DOJ explicitly indicted Cole Tomas Allen for attempting to assassinate President Trump, and described the attack as him rushing a Secret Service checkpoint and firing a shotgun while Trump was present. (justice.gov) But the May 23, 2026 White House checkpoint shooting is weaker as an input to the “true attempt” rate: AP’s account frames it as a man opening fire near/toward a White House security checkpoint, with relatively sparse public evidence on intent and no equally direct attempted-assassination charge in the basic reporting. (apnews.com)
I still do not go all the way to a very low estimate, because the resolution rule is broad in practice. It is not asking only whether a competent targeted assassination plot occurs; it also counts overt violent incidents if DOJ/FBI/USSS or enough major outlets apply “attempted assassination” language. Recent official language around Trump-related attacks has been direct, including DOJ/FBI language for both the 2024 Routh case and the 2026 WHCD case. (justice.gov) So “wording risk” is real and increases the chance that a marginal perimeter incident qualifies.
I now put somewhat more weight on the critic’s security-trough point. After repeated gunfire/security incidents, the Secret Service, FBI, local police, and White House operations have unusually strong incentives to restrict exposure, harden perimeters, and preempt obvious threats. I also agree that the G7/World Cup calendar should not be naively treated as a vulnerability spike: those events are highly planned and heavily secured; the World Cup runs June 11–July 19, and the G7 summit is June 15–17, but maximally visible events may be safer than mundane movements or perimeter incidents. (fifa.com)
My updated actionable probability for a qualifying incident on or before 2026-08-12T12:00Z is about 33–34%, down from 36%. That is still historically enormous, but it better reflects regression, post-incident hardening, definitional fragility, and the possibility that many threats remain threats/arrests rather than overt qualifying acts.
I am also fattening the right tail further. The later percentiles should be understood partly as forced-date stand-ins for “very long time / effectively never” mass: Trump is elderly, exposure may fall, security may improve, and future events may be disrupted before reaching this question’s overt-act threshold.

Reading: strict
The resolution criteria are highly specific and narrow: only incidents explicitly characterized as ‘assassination attempt’ or ‘attempted assassination’ by named official agencies (or 3-of-7 named outlets within a defined timeframe) qualify, and routine security breaches, threats, or arrests explicitly do not — this demands a strict, literal reading where the precise terminology and sourcing thresholds are determinative.

Evidence confidence: medium
medium evidence]Enhanced security posture following the April and May 2026 attacks; Secret Service re-evaluation of protocols; heightened scrutiny and congressional oversight; base-rate survival projection under the 22-month rate puts median next attempt ~3.85 months out (i.e., mid-September 2026, beyond the window); the two recent attempts may have exhausted the near-term pool of lone-offender actors; post-incident security upgrades may deter or prevent a qualifying overt act; the strict characterization threshold means even a serious incident may not officially qualify within 14 days.
Recent acceleration to ~2 qualifying incidents per month (April + May 2026) increases near-term risk; Trump has multiple high-profile public events in the window (July 4 250th anniversary, FIFA World Cup, election rallies); security is described as ‘stretched thin’; DHS has flagged elevated domestic extremist threat; the trend of recent incidents argues against a sudden pause.
medium evidence]The accelerated rate of ~0.5/month (two attempts in April-May 2026) produces a median next-attempt timing of ~1.39 months from late May 2026, placing the median around mid-July 2026 — within the observation window; Trump has major high-profile events in July (July 4 250th anniversary celebrations, FIFA World Cup); these large events present heightened security challenges per expert analysis; the DOJ has demonstrated willingness to officially characterize such incidents rapidly (April 25 indictment filed within 10 days, May 24 filing was near-immediate); lone-offender political violence is described as ‘accelerating’ by researchers.
The recent cluster may be a statistical anomaly, not a sustained rate; security is being reinforced after back-to-back incidents; not every incident receives the official ‘assassination attempt’ characterization (e.g., Feb 2026 Mar-a-Lago); enhanced security for July 4 events may reduce access.
low evidence]If the recent month-to-month cadence (April and May 2026 attempts) continues without interruption, a June 2026 incident is plausible; the threat environment from domestic extremists is described as at its highest level in five years; Trump’s schedule continues to include public appearances; the Secret Service is resource-constrained.
Post-May 24 incident, security scrutiny is at maximum; congressional and public attention is focused on vulnerabilities; the FBI and Secret Service have specifically elevated posture following the cluster; base-rate survival projections under the long-run rate put P(event within 1 month) at approximately 16-18%.
medium evidence]The Feb 22, 2026 Mar-a-Lago breach shows that even a fatal Secret Service shooting of an armed intruder at Trump’s residence was NOT officially characterized as an assassination attempt by FBI/DOJ; the strict resolution criteria require either official agency language or 3-of-7 named media outlets using precise terminology; an incident might be investigated as a mental health crisis, trespassing, or general security breach rather than assassination attempt; Trump was not at Mar-a-Lago during the Feb 2026 incident.
Both the April and May 2026 incidents received rapid official ‘assassination attempt’ characterization, suggesting the DOJ/SS are now quicker to use that language; if any future incident involves a firearm discharge in proximity to Trump, the precedent strongly supports official characterization.
inside_view_v1)Inside View Causal Analysis
Causal chain I’m tracking:
Current state: Two back-to-back officially-characterized assassination attempts in April and May 2026 (29 days apart), elevated domestic extremist threat environment, Secret Service “stretched thin,” no national counterterrorism strategy, Trump explicitly not canceling large public events (July 4, FIFA World Cup, midterm rallies).
Key causal mechanisms:
Elevated base rate → near-term risk: The 22-month base rate is ~0.18/month (4 qualifying incidents since July 2024), but the recent acceleration to ~0.5/month (two incidents in April-May 2026) is the inside-view signal. The brief’s survival projections give P(event by Aug 12) of 29-36% under long-run rate, ~75% under accelerated rate. As an inside-view forecaster, I weight the recent acceleration heavily because: (a) researchers describe lone-offender political violence as “accelerating” (source 12), (b) the threat environment is at its highest in five years (source 37), and (c) structural vulnerabilities (stretched resources, no counterterrorism strategy) persist.
Upcoming high-profile events → access opportunities: The July 4 250th anniversary celebrations and FIFA World Cup events specifically present “fresh security challenges” per expert analysis (source 24). These are exactly the kind of large outdoor events that have historically enabled attempts. Trump explicitly refuses to cancel. This pushes probability toward July timing.
Security upgrades → dampening factor: Post-incident security reviews (source 35) and elevated posture (source 33) provide some counterbalance. Back-to-back high-profile incidents create maximum congressional scrutiny. This is a real countervailing force that prevents me from fully adopting the accelerated rate.
Strict characterization threshold → discount: The Feb 2026 Mar-a-Lago incident shows not every serious incident qualifies (sources 40, 43). I apply a ~15-20% discount to overt-act probability to account for incidents that occur but fail the strict characterization threshold.
My blended probability of a qualifying event in the window (~2.5 months):
- Long-run rate gives ~36%; accelerated rate gives ~75%
- I weight the accelerated rate more (60%) because the inside view on political violence trends supports it, but discount somewhat for security upgrades
- Blended: ~0.6×75% + 0.4×36% ≈ 59%, then apply ~15% characterization discount → ~50% overall P(qualifying event by Aug 12)
Temporal distribution of the ~50% probability mass:
- June bins (first two 10-day bins): Low-evidence scenario tagged “low” — immediate aftermath of May 24 incident has maximum security scrutiny. I assign about 6% total to June.
- July bins (July 5–Aug 2): The accelerated-rate median places the next attempt at ~mid-July 2026. This is the peak of outdoor large events (July 4 250th anniversary). Most of the “yes” mass concentrates here — about 22% total.
- Early August bin (Aug 2-12): Still possible, assign ~12%.
- “After Aug 12” (bins 8-12): The remaining ~50% probability.
Distribution across bins:
- Bins 0-7 (in-window): ~50% total
- May 27-Jun 6 (bin_0): ~1% (maximum security post-May 24)
- Jun 6-16 (bin_1): ~2%
- Jun 16-25 (bin_2): ~3%
- Jun 25-Jul 5 (bin_3): ~5%
- Jul 5-14 (bin_4): ~10%
- Jul 14-24 (bin_5): ~12%
- Jul 24-Aug 2 (bin_6): ~10%
- Aug 2-12 (bin_7): ~7%
- Bins 8-12 (after Aug 12): ~50% spread across future
- bin_8: ~20% (next ~2-3 months)
- bin_9: ~12% (Oct-Jan)
- bin_10: ~8% (Jan-Mar 2027)
- bin_11: ~6% (Mar-Jun 2027)
- bin_12: ~4% (after Jun 2027)
outside_view_v1)Reference class: “officially‑characterized assassination attempts against Donald J. Trump” (events DOJ/FBI/USSS label as an “assassination attempt/attempted assassination”, or that meet the 3-of-7‑outlet fallback). Base rate: ~4 such qualifying incidents from ~July 2024–May 2026 → ≈0.18 attempts/month (≈36% chance of a qualifying attempt in the ~2.5‑month window to 2026‑08‑12) (sources 25, 26 in the brief). Adjustment: +0 pp (I do not move the base‑rate terminal probability by more than ±15 percentage points). Rationale for no large adjustment: the brief documents a recent short cluster (April and May 2026 ~29 days apart) that argues for an elevated short‑term hazard (brief cites an accelerated rate ~0.5/month and a blended estimate ~0.3/month), but the evidence strength for a sustained higher rate is medium (the brief tags the time‑to‑event projection and scenarios as medium confidence). Using the outside view, I anchor on the observed base rate (0.18/month) and therefore keep the probability of a qualifying incident by 2026‑08‑12 at ~36% (the brief’s long‑run survival projection numbers: ~35–36% by Aug 12 are reported — sources 26, 30). I note the strict interpretation of the question and resolution criteria: an event must be officially characterized as an “assassination attempt/attempted assassination” by DOJ/FBI/USSS within 14 days or by 3 of the seven named outlets otherwise; not every serious breach or fatal officer‑involved shooting is counted (the Feb 22 Mar‑a‑Lago case was NOT officially characterized as an assassination attempt — sources 40, 43, 44), which reduces effective sensitivity to some kinds of incidents. Allocation across bins: I assume a roughly constant short‑term hazard (outside view, memoryless/near‑constant rate) and therefore divide the 36% mass across the observation window bins (bin_0..bin_7) in proportion to the number of days in each bin (this yields ~0.04675 for 10‑day bins and ~0.04208 for 9‑day bins). The remaining 64% is assigned to later bins (bin_8..bin_12) as follows: a large share immediately after the window (bin_8 = 0.48) and smaller shares for later windows (bin_9 0.08, bin_10 0.05, bin_11 0.02, bin_12 0.01). This reflects the outside‑view expectation that, absent strong evidence for a sustained much higher short‑term hazard, the most likely single outcome is that the next officially‑characterized attempt will occur after the Aug‑12 cutoff, with the greatest mass in the period immediately after the cutoff. Supporting facts cited inline: 4 qualifying attempts in ~22 months → ~0.18/month (sources 25, 26); April 25 and May 24, 2026 incidents were officially characterized by DOJ/FBI as attempts (sources 19, 13) and occurred before the window; Feb 22 Mar‑a‑Lago armed breach was not so characterized (sources 40, 43, 44); security posture described as “stretched thin” and upcoming high‑profile events increase exposure (sources 39, 24). Confidence in evidence: medium (the brief labels evidence/confidence as medium; I therefore keep a moderate concentration inside the window while leaving substantial mass after the window). This is the outside‑view trajectory: anchor to the simple historical base rate, adjust only to reflect uncertainty signaled in the brief, and allocate across the provided date bins proportionally to time within the observation window and with a plausible tail afterward.
contrarian_v2)Adversarial reading
The bulk of the brief’s quantitative evidence (survival models at sources 21, 26, 30) and structural factors (post-incident security reviews at sources 33/35, elevated posture) pull toward low probability of a qualifying incident inside the ~76-day window under the long-run 0.18/month rate (~36 % by Aug 12, median ~3.85 months out), with the strict characterization rule further inflating the terminal bin.
Counter-evidence found (or absence)
The April–May 2026 cluster (~29 days apart, source 25) and the accelerated-rate survival projection (0.5/month, P(by Aug 12) ≈ 75 %, median mid-July, source 26) directly contradict the long-run consensus; the leaked DHS assessment of record domestic-extremist threat (source 37) and Trump’s July high-profile events (source 24) supply additional counter-weight.
Distribution implications
The medium-strength accelerated-rate evidence shifts material mass forward into bins 4–6 (mid-July peak) relative to a pure long-run-rate allocation, while the medium-strength “fails characterization” scenario (Feb 2026 precedent at sources 40/43) and security-upgrade evidence simultaneously boost the terminal bin (bin_12) above what a naive centroid of the four scenarios would produce.
Strategy: logit_mean • Drafts: 3/3
anchoring_v1The draft rationale explicitly blends the long-run rate (0.18/month, P≈36%) with the recent accelerated rate (0.5/month, P≈75%), weighting the accelerated rate at 60% to produce a blended ~50% P(in-window) — but this is a clear optimistic-end anchor. Two consecutive incidents 29 days apart is a sample of n=2 used to triple the long-run hazard; the modal expectation after a cluster is mean-reversion, not persistence, especially with post-incident security upgrades in place. The blended estimate should weight the long-run rate more heavily (e.g., 70/30 or 80/20 in favor of the long-run rate), producing a P(in-window) closer to 38-42% rather than ~50%. Within the in-window mass, the draft places ~18% on July 5–Aug 2 bins (bins 4+5+6) — treating the mid-July accelerated-rate median as the modal scenario — yet the long-run median of ~3.85 months puts the next attempt in mid-September (outside the window). The modal expectation is thus that the event falls outside the window, not inside it, and the inside-window mass should be concentrated later in the calendar rather than peaked at mid-July.
ceiling_v1The primary structural constraint the draft underweights is the strict characterization ceiling: not every overt incident qualifies — only those officially labeled “assassination attempt” by USSS/FBI/DOJ within 14 days or by 3-of-7 named outlets. Source 40/43 explicitly shows that a fatal Secret Service shooting of an armed intruder at Trump’s residence (Feb 22, 2026) was NOT characterized as an assassination attempt by the FBI, despite Trump being present (actually he was NOT there per source 44, which itself is a key factor in characterization). This means the effective “qualifying incident” rate is materially lower than the raw physical-incident rate. The draft applies only a “~15-20% characterization discount” but then proceeds to spread mass across June/July bins as if the discount is already baked in — yet the terminal bin (bin_8, “after window”) receives only ~24% when the long-run survival model’s P(no event in window) is ~64%, and the Weibull model’s is ~70.7%. The draft’s blended in-window probability of ~50% sits above the upper bound of the long-run model (36%) and only reaches toward the accelerated rate (75%) — but the accelerated rate is based on just 2 data points and is tagged “medium” evidence strength. The structural floor of the terminal bin implied by the conservative base rate alone is ~64%, not ~50%.
math_v1The draft forecast exhibits a significant internal inconsistency between its stated reasoning and its probability distribution. The rationale articulates a 50% overall probability of a qualifying event by Aug 12, 2026 (after applying characterization discounts to a blended 59% estimate), yet the published distribution allocates only 37.3% to bins 0–7 (the in-window bins), with 62.7% going to post-Aug-12 outcomes. The inside-view argument emphasizes the April–May 2026 acceleration cluster, elevated threat environment, and upcoming July 4 events as drivers of mid-July risk, but the allocation of 19.0% to July bins (4–6) understates this causal argument relative to the 24.2% assigned to Aug 12–Oct 28 (bin_8). This distribution skews later than the rationale’s own median timing (mid-July under accelerated rate) and narrative weight.
Reviews consumed: 3
The anchoring reviewer and ceiling reviewer both flagged that the draft over-weights the accelerated rate (n=2 cluster) vs. the 22-month long-run rate (~0.18/month → P(in-window) ~36%), and that the characterization filter (Feb 2026 Mar-a-Lago not labeled an attempt by FBI) further reduces the qualifying-incident probability. I accepted these concerns partially: I shifted in-window mass down from ~50% to ~42% and boosted the immediate post-window bin (bin_8) from 24% to ~32%, since the long-run survival model and Weibull both imply 60-70% post-window mass. The math reviewer flagged a distribution-to-rationale mismatch and argued that if the inside-view emphasis on July 4 events holds, July bins should peak higher than bin_8; I partially integrated this by keeping Jul 14-24 (bin_5) as the in-window peak at ~10% and giving July bins (4-6) ~26% total, but I did NOT adopt the math reviewer’s full 73% in-window allocation because anchoring + ceiling reviewers correctly argue the accelerated rate is overweighted. The net effect is a partial shift: in-window probability ~42% (between long-run 36% and inside-view 50%), with July as the peak in-window period but bin_8 carrying the largest single share reflecting the long-run hazard’s median falling outside the window.
[math] Math reviewer argued the rationale’s stated ~50% in-window probability should map to ~50% mass in bins 0-7, and pushed for a ~73% in-window allocation peaked sharply in mid-July.
[ceiling] Ceiling reviewer argued bin_8 alone should be 35-40% based on the Weibull model’s P(no event by Aug 12) ≈ 70.7%.

Model’s Answer:
This question requires an incident to be officially characterized as an “assassination attempt” by the Secret Service, FBI, or DOJ—or by at least 3 of the specified major news outlets within 14 days if no official designation occurs. The window runs from May 27, 2026 23:38:08 UTC to August 12, 2026 12:00:00 UTC (approximately 76 days).
Recent Incident Pattern (2026):
The May 24-25 incident occurred BEFORE the May 27 cutoff and therefore does not count for this question’s resolution.
Frequency Analysis:
Risk Factors:
Protective Factors:
Assumption 1: The accelerated incident pattern continues (~1/30-45 days)
Assumption 2: At least ~50% of security incidents get officially characterized as “assassination attempts”
Assumption 3: Trump maintains his announced public schedule
Earlier Outcome Scenario: If the ~30-45 day pattern holds from the April 26 incident, the next qualifying attempt could occur in late May through mid-June. The ongoing elevated threat environment and Trump’s refusal to curtail public events support this. Likelihood: ~20%
Later Outcome Scenario: If enhanced security measures prove effective, or if the recent uptick was anomalous, or if incidents occur but don’t meet the strict “assassination attempt” characterization criteria, no qualifying event may occur by August 12. The fact that the May 24-25 shooting was NOT characterized as an assassination attempt despite involving gunfire near the White House suggests high evidentiary bar. Likelihood: ~45%

Presidential-assassination attempts are historically rare and constrained by enduring protective architectures and legal bottlenecks.
Those structural limits are offset by elevated exposure from frequent public events, high-profile targeting, and an unusually dense stream of armed approaches.
A recent cluster of charged or publicly reported armed approaches has raised operational pressure on perimeter security and prosecutorial attention.
Rising threat reports and a surge in assessed threat cases increase detection and public visibility even as many approaches are intercepted.
Large public venues and scheduled national events concentrate risk in time and space and create clear inflection windows for attack opportunities.
Each intercepted or charged attempt triggers rapid hardening of routes and checkpoints, which materially reduces near-term success probability.
Key uncertainties include undisclosed disrupted plots, variable event schedules, and whether the Secret Service, FBI, or DOJ will apply the exact ‘attempted assassination’ label.
Outcome sensitivity is high to small-sample clustering and to whether perimeter incidents receive the specific official terminology required for resolution.
Median (P50): No consensus — forecasters diverge on whether an event occurs in the 76-day window (May 28–Aug 12, 2026)
Base rate is thin but elevated. Three assassination attempts against Trump occurred in ~22 months (July 2024–May 2026), implying ~1.6 per year. Over the 76-day window, a Poisson model yields ~27–30% baseline probability. However, only ~50% of armed incidents near Trump receive official “assassination attempt” characterization, which compresses the effective rate.
July 4 National Mall keynote is the highest-risk single event. Trump is scheduled to address 1M+ people at the same venue where a shooting occurred on May 4, 2026. Multiple forecasters identify this as a probability spike, though estimates of its marginal contribution vary (5–15 percentage points).
Active Iranian threat is credible but interdicted. The US killed Khamenei on Feb 28, 2026; Iran vowed revenge; IRGC operative Farhad Shakeri remains at large with documented Trump-targeting plots. This pushes probability upward, but the extent of operational capability on US soil is unknown and may be overstated.
Domestic copycat risk is explicit but uncertain. Three armed incidents occurred in Feb–May 2026; former DHS officials warn of copycat acceleration. However, the characterization threshold filters out incidents that don’t meet the legal/media definition of “assassination attempt.”
Security reviews post-April 25 are underway but unconfirmed. The April 25 incident (Cole Tomas Allen at Correspondents’ Dinner) triggered protocol reviews, but actual implementation of new measures is not yet confirmed, limiting downward adjustment.
Forecasters split on whether the event occurs in-window. Estimates of P(qualifying attempt by Aug 12) range from
