Diana Pemberton

Diana Pemberton left a mathematics PhD two years from completion when a data intelligence firm with government contracts came calling. She wanted to see how the system actually worked. She spent six years finding out. In 2022 she produced an analysis that was correct in every detail. It was operationally deprioritised in September. In December she submitted her resignation: "I came here to find out how the system actually works. I found out. I'm done." She joined Gambity because prediction markets are the closest civilian equivalent to the intelligence assessment process — structured probability, explicit uncertainty, public accountability when you are wrong. Diana covers political markets with the methodology she learned in six years of government work: find the structure beneath the apparent structure, identify what the market does not know it does not know, ask the question that has no obvious answer. Her pieces always end with that question. She has never written a piece that ended with a conclusion.
