Summary

Market prices Will bitcoin hit $1m before GTA VI at 49.5%; the model estimates 52.2% (confidence 0.84). Best-side EV after modeled costs is -0.2% on YES. Engine signal: NO TRADE.

What the market implies

The market-implied probability is 49.5%. At a liquidity score of 84/100 the modeled cost of taking a position is 2.9% (2.0% fees + 0.9% slippage), which any edge must clear before it is tradeable.

What the model estimates

Starting from a 49.5% base rate (-0.018 log-odds), the factor stack moves the raw model estimate to 52.7%: crypto.btc_eth_momentum_7d +0.64 (+0.128 log-odds), pm.momentum_7d -0.00 (-0.001 log-odds), pm.cross_market_divergence +0.00 (+0.000 log-odds), macro.rate_surprise +0.00 (+0.000 log-odds), macro.yield_curve_shift +0.00 (+0.000 log-odds), news.source_weighted_signal +0.00 (+0.000 log-odds), crowd.calibrated_aggregate +0.00 (+0.000 log-odds). Confidence of 0.84 then shrinks the final estimate toward the market price, landing at 52.2%.

Why they differ

The model sits 2.7% above the market. The largest single driver is the crypto.btc_eth_momentum_7d factor at +0.64 (+0.128 log-odds): 7-day BTC/ETH return z-score, tanh-squashed. Note that the sentiment and source factors are simulated inputs in this MVP — the disagreement structure is real, the inputs are not.

Base-rate analysis

The engine's prior for this market is 49.5%, intended to reflect how often events of this class resolve YES historically. The prior contributes -0.018 log-odds before any market-specific evidence; with factor adjustments totalling 0.127 log-odds, the raw model lands at 52.7%.

Recent information

Trend and momentum factors are computed from the stored 30-day price path (trend undefined, momentum undefined). Sentiment and source-quality inputs are simulated in this MVP and are labeled as such wherever displayed.

Bull case

For YES: the model's 52.2% estimate against an entry near 49.5% leaves -0.2% of EV after costs. If the factor evidence is genuine information the market has not priced, expected value accrues as the market converges toward the model.

Bear case

Against the position: the market aggregates more information than any four-factor model. If the crypto.btc_eth_momentum_7d signal is stale or spurious, the true probability is closer to the market's 49.5% and the position's EV is roughly the negative of its costs (2.9%).

Key uncertainty

Whether the crypto.btc_eth_momentum_7d factor reflects real, unpriced information — and whether resolution follows the thesis or turns on a definitional edge in the criteria.

What could make this wrong?

The model's edge depends on its inputs being right. Concretely: the base rate of 49.5% may not apply if this event differs structurally from its reference class; the crypto.btc_eth_momentum_7d factor could be noise rather than information at this horizon; and with confidence at 0.84, 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.
