LLMs and prediction markets reveal bias in English news on Ukraine

A new research paper proposes using Large Language Models (LLMs) in conjunction with prediction markets to quantify information bias within text corpora. The study applied this method to 111 Ukraine-related prediction markets, involving approximately 93,000 predictions across four LLM architectures. Findings indicate that English news sources systematically introduce bias in territorial predictions, leading to inaccuracies 64-72% of the time. The research suggests that while supplementing with Ukrainian military-analytical sources can reduce this bias, the distortion originates primarily from the text sources themselves, not the LLMs processing them.

    Belief Propagation in LLM World Models: Measuring Strategic Information Bias with Prediction Markets

    arXiv:2607.20441v1 Announce Type: new Abstract: Every information ecosystem produces beliefs that shape strategic decisions. Both human analysts and AI systems inherit the blind spots of their information sources. We show that LLMs, combined with prediction markets, function as a…
