The Monte Carlo/trend analysis anchors the central and tail estimates of the daily peak, while news tools adjust for whether a major exercise-driven surge (upside) or continued pause (downside) is likely; these correlated factors blend via weighted average into a final numeric distribution.

Sub-questions (4)

sq1
Will the peak single-day PLA aircraft incursion in July-August 2026 exceed the historical median peak (around 30-40 aircraft) implied by the base-rate spreadsheet?
Establishes the baseline distribution of daily peaks from historical data, anchoring the central estimate.
w=0.35
sq2
Will there be a major military exercise or political escalation (e.g. Joint Sword-style drill, high-profile Taiwan/US event) during July-August 2026 that drives a large surge?
The record peaks (70+, even 100+) occur during named large-scale exercises, so this drives the upper tail of the distribution.
w=0.30
sq3
Will the recent trend of reduced/paused PLA ADIZ activity persist into July-August 2026, suppressing the daily maximum?
The description notes noticeable pauses that could keep peaks lower than the upward trendline suggests.
w=0.20
sq4
Will the multi-year upward trendline in PLA activity continue such that the 2026 peak exceeds prior-year summer peaks?
Captures secular growth in incursion intensity that would push the peak higher year-over-year.
w=0.15

Rationale

(a) The question resolves after Aug 31, 2026, roughly two months of daily observations, so it's a max-over-~62-days statistic. (b) Status quo: with the recent noted pause and US-China thaw, a quiet summer might still produce at least one elevated day of ~30-45 aircraft, as even suppressed periods have occasional surges. (c) The multi-year upward trend and Monte Carlo simulations suggest a central peak in the 45-60 range, though the fit is weak (r=0.2). (d) Base rates: normal-month single-day peaks run ~30-45; named large-scale drills (Joint Sword-style) push peaks to 70-150+, which under the 60.5 cap would resolve at the maximum. (e) Low scenario (p10): the pause persists amid US-China détente (Xi's Sept White House visit, arms-sale delays), keeping the summer max around 22-25. (f) High scenario (p90): a Trump-Lai call or Taiwan political provocation triggers a large exercise, driving a single-day count above 60, capped at the range ceiling. Given the escalation triggers coexisting with détente signals, I center the distribution around the mid-40s with wide tails, placing meaningful mass near the 60 cap to account for the drill tail.

## Question
What will be the highest daily number of PLA aircraft tracked by Taiwan's Ministry of National Defense in Taiwan's air-defense identification zone (ADIZ) in July-August 2026?

## Description / Resolution Criteria
## Description
As an early warning system for its defense, Taiwan carefully tracks an air-defense identification zone, with a typical recent map being as follows (in this case a report of 10 crossing into the ADIZ airspace): 

![](https://www.mnd.gov.tw/NewUpload/202606/1150625_%E8%87%BA%E6%B5%B7%E5%91%A8%E9%82%8A%E6%B5%B7%E3%80%81%E7%A9%BA%E5%9F%9F%E6%B4%BB%E5%8B%95%E7%A4%BA%E6%84%8F%E5%9C%96_212012.jpg)

Base rate information can be found at the /PLATracker Taiwan ADIZ Violations spreadsheet [here](https://docs.google.com/spreadsheets/d/1qbfYF0VgDBJoFZN5elpZwNTiKZ4nvCUcs5a7oYwm52g/edit?gid=905433190#gid=905433190), and daily numbers can be conveniently tracked at Taiwan's official [MOD X account](https://x.com/MoNDefense). According to /PLATracker, the numbers show an upward trendline over the past few years: 

![](https://cdn.metaculus.com/user_uploaded/Screenshot_2026-06-25_at_4.50.33PM.png)There have lately been noticeable [pauses](https://tsm.schar.gmu.edu/all-quiet-in-the-taiwan-strait-explaining-the-recent-drop-in-pla-aircraft-activity-around-taiwan/) in PLA activity around the ADIZ, however, creating a murky situation to predict. 

`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 44245, "question_id": 44254}}`

## Resolution Criteria
This question resolves as the highest number of PLA aircraft accused by Taiwan's Ministry of National Defense (MND) of having been detected in Taiwan's de facto ADIZ for any date after June 30, 2026 and before September 1, 2026, as reported by the MND at its [Regional Dynamic List ](https://www.mnd.gov.tw/news/plaactlist)portal. 

## Fine Print
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44245) which opened on 2026-06-26 20:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.

## Range
The answer must be a number in [-0.5, 60.5] (units: aircraft).

## Sub-question decomposition (planner)
- (w=0.35) Will the peak single-day PLA aircraft incursion in July-August 2026 exceed the historical median peak (around 30-40 aircraft) implied by the base-rate spreadsheet?  — Establishes the baseline distribution of daily peaks from historical data, anchoring the central estimate.
- (w=0.30) Will there be a major military exercise or political escalation (e.g. Joint Sword-style drill, high-profile Taiwan/US event) during July-August 2026 that drives a large surge?  — The record peaks (70+, even 100+) occur during named large-scale exercises, so this drives the upper tail of the distrib
- (w=0.20) Will the recent trend of reduced/paused PLA ADIZ activity persist into July-August 2026, suppressing the daily maximum?  — The description notes noticeable pauses that could keep peaks lower than the upward trendline suggests.
- (w=0.15) Will the multi-year upward trendline in PLA activity continue such that the 2026 peak exceeds prior-year summer peaks?  — Captures secular growth in incursion intensity that would push the peak higher year-over-year.

## Required pre-forecast walkthrough

Before giving percentiles, address these explicitly in your rationale:
  (a) The time left until the question resolves.
  (b) The outcome if NOTHING changes from today (the status quo value).
  (c) The outcome if the CURRENT TREND continues.
  (d) The expectations of experts / markets / base rates.
  (e) A plausible scenario that produces a LOW outcome (near p10).
  (f) A plausible scenario that produces a HIGH outcome (near p90).

## Calibration guidance

- **Be humble about tails.** Good forecasters set WIDE 90/10 intervals to account for unknown unknowns. Narrow tails get punished by the log score far more than slightly-biased medians.
- **Status quo anchoring.** The p50 should be close to the status quo value unless you have strong evidence of a trend.
- Don't pile mass at one value — if you're tempted, widen the spread by 20-50%.
- **Anchor on markets/experts.** If liquid market prices, analyst forecasts, or community percentiles appear in the evidence, center your distribution on them and widen — don't override a liquid market without specific evidence it lacks.

(b) Status quo: with the recent noted pause and US-China thaw, a quiet summer might still produce at least one elevated day of ~30-45 aircraft, as even suppressed periods have occasional surges. (c) The multi-year upward trend and Monte Carlo simulations suggest a central peak in the 45-60 range, though the fit is weak (r=0.2). (d) Base rates: normal-month single-day peaks run ~30-45; named large-scale drills (Joint Sword-style) push peaks to 70-150+, which under the 60.5 cap would resolve at the maximum. (e) Low scenario (p10): the pause persists amid US-China d\u00e9tente (Xi\u0027s Sept White House visit, arms-sale delays), keeping the summer max around 22-25. (f) High scenario (p90): a Trump-Lai call or Taiwan political provocation triggers a large exercise, driving a single-day count above 60, capped at the range ceiling. Given the escalation triggers coexisting with d\u00e9tente signals, I center the distribution around the mid-40s with wide tails, placing meaningful mass near the 60 cap to account for the drill tail."
