What this index is

The WW3 Chance Index is a weighted probabilistic signal aggregator. It ingests geopolitical news from major international sources every 2 hours, classifies each event using an AI model, assigns a numerical escalation weight, and computes a composite probability score.

It does not predict the future. It measures the current density and direction of escalatory signals across active global conflict zones — and translates that into a single, trackable number.

This is a data signal tool. It is not intelligence analysis, military assessment, or a prediction service. The methodology is designed to be transparent, reproducible, and conservative.

Data sources

The index ingests RSS feeds from the following sources, checked every 2 hours:

BBC World
Reuters
CNN World
Al Jazeera
Sky News
France 24

Articles are deduplicated by URL hash. Only articles relevant to military conflict, diplomatic relations, weapons, or geopolitical tension are processed. Irrelevant articles (sports, entertainment, domestic politics) are discarded.

Event classification

Each relevant article is passed to an AI classifier (Gemini 2.0 Flash) with a fixed scoring prompt. The classifier assigns:

Weight calibration

The weight scale is anchored to real-world severity. These are fixed reference points used to train consistent classification:

WeightEvent type
+3.0Nuclear weapon used, or direct credible nuclear threat with military posture
+2.0Direct strike on sovereign territory by a major power (US, Russia, China)
+1.5Major chokepoint closure (Hormuz, Bosphorus) or carrier group deployment
+1.0Confirmed airstrike, missile launch, or cross-border military incursion
+0.5Major military mobilisation or formal war declaration
+0.3Significant escalatory rhetoric from head of state or defence minister
+0.1Minor proxy skirmish, localised incident, unconfirmed reports
0.0Routine exercise, diplomatic statement, or unverified claim
−0.3Ceasefire announcement or peace talks initiated
−0.5Confirmed diplomatic backchannel or mediator engagement
−1.0Troop withdrawal, military stand-down, or formal agreement signed
−2.0Major peace deal or conflict resolution

Index calculation

The global index is computed from all events in the last 72 hours. Recent events are weighted more heavily using exponential time decay:

decay(event) = weight × e^(−0.03 × hours_ago)
rawScore = Σ decay(all events in 72h window)
probability = 1.5 + (clamp(rawScore, 0, 50) / 50) × 28

The half-life of any event is approximately 23 hours — meaning an event scored at +1.0 will contribute +0.5 to the index the following day, and approximately +0.25 two days later.

The output is mapped to a range of 1.5% to 29.5% under normal conditions. Values above 30% are reserved for confirmed nuclear events or direct superpower military engagement — thresholds that have never been triggered in the post-Cold War era.

What the numbers mean

RangeInterpretation
0–5%Background geopolitical noise. Normal tension levels, no major active escalation vectors.
5–15%Elevated. Active military posturing or significant diplomatic failure in at least one major zone.
15–30%High alert. Multiple zones escalating simultaneously with direct superpower involvement.
30%+Critical threshold. Reserved for nuclear use, direct US-Russia or US-China kinetic conflict.

Limitations

This index has deliberate limitations you should understand:
