Prediction Market Auditability
Verifiable records for event-market operators, compliance teams, data vendors, and researchers. Tamper-evident audit trails for the predictions, market snapshots, and resolution actions that drive event markets.
CertifiedData supports auditability. It does not certify outcomes, ensure compliance, or evaluate fairness. What it does is produce machine-verifiable evidence of what the platform claimed and when.
Why prediction markets need audit trails
Markets close quickly, evidence does not
Event markets resolve over hours, days, or weeks. The record of what the market showed and when it showed it must outlast the market itself — often for audit windows measured in years.
Resolution is the highest-stakes step
When an outcome is recorded, settlement follows. The resolver action — and the evidence reference behind it — becomes the canonical record of what happened. Without signing and timestamping, that record can be revised.
Operators publish snapshots to many audiences
Market state at a point in time is shown to traders, to regulators, to data vendors, to media. Without a signed snapshot, every audience sees what the operator chooses to render — at the moment of rendering.
Forecast models behind markets need lineage
If an AI model produces forecasts that feed market signals or settlement logic, the model version, input data, and approval events all need to be traceable to the published market record.
What gets certified
Five complementary layers. Each is independently verifiable. Together they form a complete audit trail for AI-driven event markets.
Each AI-generated forecast that feeds market signals is certified at issuance. The forecast cannot be revised after the outcome is observed.
Certified predictions →The complete daily set of AI-generated forecasts is bundled into a manifest certificate, preventing selective disclosure.
Daily prediction manifest →Market data at a point in time — price, volume, open interest, liquidity — is canonicalized, hashed, and signed. The snapshot becomes a verifiable artifact independent of the platform's mutable APIs.
Certify market snapshots →When a market resolves, the resolution payload — outcome, resolver identity, evidence reference, rules hash — is certified. The settlement record is bound to the evidence it cited.
Certify resolution records →The decision events behind every market action — resolver approvals, model updates, manual overrides — are appended to a tamper-evident decision log. CertifiedData proves the record; Decision Ledger proves the process.
Decision Ledger →Who uses prediction market audit trails
| Audience | CertifiedData surface |
|---|---|
| Event-market operators | Certified market snapshots + signed resolution records + Decision Ledger lineage. |
| Compliance teams | Certificate transparency log + Decision Ledger audit trail. |
| Market data vendors | Certified market snapshot receipts with public verification URLs. |
| Researchers and academics | Public certificate registry + daily manifest certification. |
| Institutional traders | Direct verification via /verify, no platform account required. |
What CertifiedData does and does not claim
- Pre-outcome timestamping of predictions
- Tamper-evident records of market state
- Signed resolution payloads with evidence references
- Independent verification by any party
- Provable provenance for AI forecasts
- Predictions are accurate or profitable
- Market resolution is correct
- The platform is regulator-approved
- Compliance with any specific jurisdiction
- Gambling-license eligibility
The certificate proves the record. Whether the record is right, fair, or compliant is a separate question that requires separate evaluation.
