Pro features — the Opportunities Scanner, Strategy Builder, Calibration Edge overlay, and unlimited watchlist — require an active Pro subscription.

Refund requests must be submitted to info@fieldestimate.org with your account email and reason for cancellation. Refunds are issued to the original payment method within 5–10 business days.

Refunds are not available after the 30-day window, in cases of account termination for Terms violations, or for team subscription seat adjustments within an active billing period.

8. AI-Generated Content

Nature of AI outputs

Field Estimate uses Anthropic's Claude AI model to synthesize news briefings, suggest causal factors for forecasts, generate historical reference classes and base rates, match prediction market contracts to daily news, and produce weekly trend analyses. All AI-generated content is informational only and may contain errors, omissions, inaccuracies, or outdated information. The AI synthesizes and summarizes source material; it does not independently verify facts.

AI outputs are provided as analytical starting points to support your own research and judgment. They are not a substitute for primary source journalism, professional research, or expert analysis. AI-generated analysis should not be relied upon as financial advice, investment advice, trading recommendations, or any other form of professional advice.

No guarantee of completeness

Briefing coverage reflects what is available in search results at the time of generation. AI-suggested causal factors and reference classes are not exhaustive. The Service does not comprehensively monitor world events and may not capture all significant developments in a given region or topic area on any given day.

AI limitations

AI-generated content may occasionally reflect inaccuracies present in source material, generate plausible-sounding but incorrect information, or fail to distinguish between unverified claims and confirmed facts. We make no warranty as to the accuracy, completeness, or timeliness of any AI-generated content. Users should verify important information through primary sources before acting on it.

Your data and AI processing

Your configured preferences (regions, countries, topics) and forecast context (question text, causal factors) are passed to the AI model as inputs. Briefing content and market contract descriptions are processed through OpenAI's embedding model for semantic search and trend analysis. This data is processed by Anthropic and OpenAI subject to their respective privacy policies and data processing agreements. We do not knowingly transmit other personally identifying information to these AI providers.

9. Forecasting Tools and Prediction Market Data

Research Workspace

The Research Workspace provides a structured methodology for geopolitical forecasting research. AI-suggested causal factors, reference classes, and base rates are analytical aids, not definitive assessments. You are responsible for your own forecasting conclusions.

Prediction market data

The Service displays live contract prices from Polymarket, Kalshi, and PredictIt, as well as community forecast data from Metaculus and Manifold, for informational and research purposes only. Field Estimate is a research tool, not a trading platform, exchange, or broker. No trades are executed on this platform. No funds are held by this platform. We do not facilitate, execute, or recommend trades on any prediction market. Prediction market prices reflect the views of those markets' participants and are not endorsed or verified by us.

Prediction market data may be delayed, incomplete, or inaccurate. We make no warranty as to the timeliness, accuracy, or availability of any market data displayed. Users who wish to trade on prediction markets should visit the respective platforms directly.

Brier scores and calibration

The Forecast Journal tracks your calibration using Brier scores and resolution outcomes. These metrics measure the accuracy of your probability estimates over time. Historical calibration data shows tendencies, not guarantees of future accuracy. Calibration scores are personal performance indicators and should not be interpreted as endorsement of any particular forecast, outcome, or trading position.

Risk scores

Any risk scores, probability estimates, or confidence indicators displayed within the Service are informational only and are not recommendations. They reflect algorithmic outputs or user-entered values and should not be treated as advice to take or avoid any position on any prediction market or financial instrument.

Economic data

The Economics Dashboard displays macroeconomic indicators from FRED (Federal Reserve Economic Data). This data is publicly available and is displayed for informational context only. We do not guarantee its timeliness or accuracy beyond what FRED provides.

10. Third-Party Data Sources and Attribution

Field Estimate aggregates data from multiple third-party sources to power its research tools. The following data providers are used:

  • Polymarket — prediction market contract prices and metadata
  • Kalshi — prediction market contract prices and metadata
  • PredictIt — prediction market contract prices and metadata
  • Metaculus — community forecast aggregation and probability estimates
  • Manifold — community forecast aggregation and probability estimates
  • Tavily — multilingual news search (English, Arabic, Farsi, Hebrew) for briefing generation
  • FRED (Federal Reserve Economic Data) — macroeconomic indicators for the Economics Dashboard
  • Anthropic (Claude AI) — AI model for content synthesis and analysis
  • OpenAI — embedding model for semantic search and trend clustering

Field Estimate does not own, edit, endorse, or guarantee the accuracy of any third-party content or data. Source links and attributions are provided where available for your reference.

We are not responsible for the content, privacy practices, or terms of service of any third-party data provider, news publisher, prediction market, or website linked in the Service.

11. No Professional or Financial Advice

All content provided through the Service — including briefings, AI-suggested causal factors, reference classes, prediction market prices, Brier scores, risk scores, economic indicators, community forecasts, and trend analyses — is for general informational and research purposes only and does not constitute:

  • Financial, investment, or trading advice or recommendations;
  • Solicitation or endorsement of any prediction market position;
  • A recommendation to buy, sell, or hold any contract on any prediction market;
  • News media analysis or finished research products;
  • Legal advice or legal analysis;
  • Medical or health advice;
  • Any other form of professional or expert advice.

You should not rely on the Service to make financial decisions, trading decisions, or any other decisions requiring professional judgment. We expressly disclaim any liability arising from reliance on any content provided through the Service.

12. Prediction Market Risk Disclosure

Prediction markets involve risk of loss.If you choose to trade on prediction markets, you do so independently and at your own risk. Field Estimate does not execute trades, hold funds, manage accounts, or provide access to any prediction market. Users who wish to participate in prediction markets should visit the respective platforms directly (e.g., Polymarket, Kalshi, PredictIt) and review those platforms' own terms of service, risk disclosures, and applicable regulations.

Past performance of any forecast, calibration score, or prediction market contract is not indicative of future results. Market data displayed on Field Estimate is for research purposes only and should not be the sole basis for any trading decision.

Users must be of legal age and must comply with all applicable laws and regulations in their jurisdiction regarding prediction markets, including any restrictions on participation, trading, or wagering.
