Why this is not actionable
The model can still be informative here, but one or more gates blocks a trade call.

Why this read matters
The model may disagree with price, but the gates say the disagreement is not actionable right now.

Why the engine declines to trade this market
- - No edge after fees and slippage — the market price is fair within costs.
Declining to trade is a feature: most markets are priced fairly within costs, and the risk gates run before any edge is considered.
Market-implied vs model probability
Factor attribution
The model estimates a 2-point higher probability than the market, primarily driven by 7-day price momentum.
| FACTOR | SIGNAL | WEIGHT | LOG-ODDS ΔLog-odds contribution measures how much each factor shifted the model's probability estimate in log-odds space — the mathematically correct way to stack independent evidence. Formula: Δlog-odds = weight × signal. Positive values push the probability up; negative values push it down. Log-odds are converted back to probability via the logistic function at the end. | DIRECTION | DESCRIPTION |
|---|---|---|---|---|---|
| Historical base rate | 50% | — | 0.000 | Neutral | Historical frequency for this kind of event — the prior before any market-specific evidence. |
| Cross-market divergence | —This factor was not available for this market. No approved cross-venue link exists for this market. | 0.20 | — | — | Whether the same event is priced differently on another venue. A gap may signal an opportunity or a structural difference. |
| 7-day price momentum | +0.04 | 0.35 | +0.014 | Neutral | 7-day drift of the market's own implied probability — sustained moves carry information. |
| BTC/ETH 7-day momentum | —This factor was not available for this market. This factor applies to crypto markets only. | 0.20 | — | — | 7-day Bitcoin or Ethereum return, normalized. Applied to crypto-category markets only. |
| Rate surprise | —This factor was not available for this market. This factor applies to Fed, CPI, and macro markets only. | 0.25 | — | — | 2-year Treasury yield reaction in the 48 hours after the most recent scheduled release — a proxy for how markets interpreted the data versus expectations. |
| Yield curve shift | —This factor was not available for this market. This factor applies to Fed, CPI, and macro markets only. | 0.15 | — | — | 30-day change in the 10-year minus 2-year Treasury spread. A flattening curve signals tightening expectations; steepening signals easing. |
| News signal | —This factor was not available for this market. No news signal available for this market in the past 14 days. | 0.25 | — | — | Reliability-weighted direction of relevant news from the past 14 days. Official sources (filings, agency statements) carry more weight than commentary. |
| Crowd forecast | —This factor was not available for this market. Insufficient forecasters to compute crowd signal. Requires at least 5 calibration-weighted estimates. | 0.20 | — | — | Calibration-weighted average of user probability estimates. Only applied when 5 or more weighted forecasters have submitted estimates. |
| Model probability | 50.3% | Prior: 50% · Market: 48.0% | |||
| Confidence (λ)Confidence λ (lambda) controls how much weight to give the model vs. the market. Formula: p_final = λ·p_model + (1−λ)·p_market. λ is derived from data quality, factor agreement, and liquidity. When inputs are weak, the model shrinks toward the market — not toward 50%. | 0.78 | Final: 49.8% = λ·model + (1−λ)·market | |||

Scenario treeEngine template
Node probabilities are conditional on the parent; hover for cumulative path probability. Leaf EV is per $1 YES contract at the current price, before fees (fee-adjusted EVs in the table on the left).
| Path | Path prob. | YES pays | EV (YES, after costs) |
|---|---|---|---|
| Print at or below threshold > Clearly below (≥0.2pp) | 27.4% | $1 | +48.9c |
| Print at or below threshold > Just at / rounding-dependent | 22.4% | $1 | +48.9c |
| Print above threshold | 50.2% | $0 | -51.1c |
Root-implied probability 49.8% reconciles with the model's 49.8% (±1pt invariant).
Why this mattersTemplate (no LLM key)
A 1.8% probability gap at a 48.0% price translates to -1.3% expected value per dollar of payout exposure after costs on the YES side. EV — not the raw probability gap — is the comparable number: the same gap is worth very different amounts at 50¢ and at 92¢.
What could make this wrongTemplate (no LLM key)
The model's edge depends on its inputs being right. Concretely: the base rate of 50.0% may not apply if this event differs structurally from its reference class; the pm.momentum_7d factor could be noise rather than information at this horizon; and with confidence at 0.78, the model itself concedes meaningful estimation error. The risk engine also flags: No edge after fees and slippage — the market price is fair within costs.
- - Risk score 33/100 — composite of liquidity, volatility, time-to-resolution, data quality and category risk.
- - Factor agreement 1.00: factors broadly agree, but shared blind spots are possible.
- - Data quality 0.54 (simulated input in MVP).
- - Simulated model values — this brief demonstrates structure, not live research.
Description
Resolves based on the BLS CPI release for May 2026 data. The model sees a slight edge but not enough for a directional trade.
Resolution criteria (verbatim, with analyzer flags)
analyzed by heuristicResolves YES if the Bureau of Labor Statistics reports Core CPI (excluding food and energy) below 2.8% year-over-year for May 2026.
Resolves Sat, 20 Jun 2026 03:48:52 GMT. The contract pays on these exact criteria, not on the thesis.

Live open-market tracking
Since the first stored model read on 2026-06-09, the market has moved from 48.0% to 48.0%.
This is a directional diagnostic for unresolved markets, not final performance. Resolved outcomes still determine the official live record.
Data quality54/100 - weak
Missing: Cross-market divergence, Rate surprise, Yield curve shift, News signal, Crowd forecast
When features are unavailable, the model increases uncertainty and weights the final estimate closer to the market price. Lower data quality does not mean the market is wrong. It means the model is being appropriately humble.
