Researchers have developed new methods to evaluate the forecasting abilities of large language models (LLMs) by addressing issues of data leakage and calibration. One approach, Hindcast, replays prediction markets from a specific past date, preventing models from accessing post-event information or training data that includes future outcomes. Another study probes LLMs' internal representations to assess their calibration and the faithfulness of their reasoning. This research found that internal activations provide a more reliable signal for calibration and can act as lie detectors, revealing that forecasts are often determined before the reasoning process begins.
