Research and intelligence for the selected market:
AI-powered analysis of the selected market. The intelligence brief appears at the top with edge assessment, timeline, momentum, smart money, data quality, and contrarian view. Below that: verdict (STRONG YES through STRONG NO), confidence score with bar, summary, key factors, and news impact with directional arrows. A Deep Analysis button upgrades to the premium model for higher-quality reasoning.
All barometers use the same methodology: filter markets by sector, group into zones via keyword matching, calculate volume-weighted YES% as the score, and display top 4 markets per zone. Click any market row to select it.
AI-powered market intelligence, scenario analysis, and recommendation engine. Three modes:
The Models tab derives an estimated true probability by combining 11 independent signal sources. Each source shifts the estimate away from the market price when evidence supports it:
| Source | What it measures | Max shift |
|---|---|---|
| AI Verdict | Directional lean from AI analysis, weighted by confidence | +/- 8% |
| 7-Day Price Change | Recent price momentum direction (clamped) | +/- 5% |
| Whale Sentiment | Net whale flow: accumulating vs distributing | +/- 1.5% |
| Holder Conviction | YES/NO holder balance ratio | +/- 1% |
| Smart Money Edge | Institutional flow direction and conviction score | +/- 1.5% |
| Depth Imbalance | Order book bid/ask ratio | +/- 2% |
| Volume-Price Divergence | Volume vs price trend mismatch (early reversal signal) | +/- 2% |
| Buy Pressure Trend | Recent buy/sell ratio vs historical | +/- 2% |
| Holder Rotation | Cross-reference of holder balance with whale flow direction | +/- 2% |
| Momentum Direction | BULLISH/BEARISH/FLAT classification | +/- 2% |
Confidence scales with the number of available sources. 8+ sources = full confidence. Fewer sources = proportionally reduced shift. Final estimate is clamped between 1% and 99%.
Optimal bet sizing: f* = (bp - q) / b. Four levels: Full Kelly (max growth), Half Kelly (recommended), Quarter Kelly (conservative), and Empirical Kelly (uncertainty-adjusted). Signal classification: STRONG MODERATE MARGINAL NO EDGE
Empirical Kelly applies a CV (coefficient of variation) haircut to Half Kelly: f_empirical = f_half * (1 - CV_edge). More confirming signals = lower CV = sizing closer to theoretical. Fewer signals = higher uncertainty = more conservative sizing. Based on institutional methodology from Becker (2025) prediction market microstructure research.
Based on empirical analysis of 72.1M+ trades (Becker 2025). Markets under 10% implied probability are flagged as Longshot Bias Zone: 1-cent contracts win only 0.43% vs 1% implied (-57% mispricing). Takers buying YES at extreme low probabilities lose at systematically elevated rates. Markets 10-20% get a moderate warning. Markets above 90% get a favorite bias flag. This is the calibration bias that hedge funds exploit.
Every trade has a maker (limit order) and taker (market order). Research proves takers exhibit negative excess returns at 80 of 99 price levels. The order book now shows taker cost classification (LOW/MODERATE/HIGH) based on spread width. Wide spreads mean market orders cost more edge. Use limit orders when possible.
1,000-5,000 simulations (tunable) of bounded random walk price paths in [1%, 99%]. Box-Muller normal distribution with antithetic variates and stratified sampling for variance reduction (~4x effective quality). Outputs a 20-bucket histogram, percentile ranges (5th/25th/50th/75th/95th), paths above 50%, mean and standard deviation. Note: this simulates price noise, not resolution outcomes -- real-world events determine if a market resolves YES or NO. Volatility sourced from enriched data when available, falls back to calibration default.
EV per dollar wagered for both YES and NO sides. ROI calculation, breakeven probability, and edge detection (fair value minus market price).
Daily price erosion toward resolution. Daily theta (cents/day), implied annualized volatility, time value remaining, and convergence rate.
Information-theoretic edge metric shown in the EV card. KL = p*log(p/q) + (1-p)*log((1-p)/(1-q)) where p = model estimate and q = market price. Unlike flat edge (model - market), KL auto-adjusts for extreme prices: moving from 5% to 15% is a bigger information shift than 50% to 60%. Signal levels: STRONG KL > 0.05, MODERATE KL > 0.02, WEAK KL < 0.02.
Live pre-trade calculator in the Book tab. Type any dollar amount and instantly see your real volume-weighted average fill price by walking actual order book levels. Shows BUY YES (crossing asks) and SELL YES (hitting bids) side by side. Each side shows: VWAP vs best price, total shares acquired, slippage percentage (LOW < 2%, MOD 2-4%, HIGH > 4%), and a level-by-level breakdown showing how your order eats through the book. Flags PARTIAL when the book can't fill your full order. Essential for estimating real execution cost before entering a position.
Fits an effective LMSR (Logarithmic Market Scoring Rule) liquidity parameter from the live order book. Shows your price impact at $50, $100, $500, and $1,000 order sizes. Liquidity classification: DEEP (b > 5000, institutional-grade), MODERATE (b 1000-5000), THIN (b 200-1000, significant impact), ILLIQUID (b < 200, your trade IS the price movement). If your order size exceeds 30% of effective-b, your edge is partially illusory because you move the price against yourself.
Sequential Bayesian updating. Starts from a prior (market price or sector base rate) and chains through each signal as a likelihood ratio update via Bayes' rule. Signals: whale flow (LR 1.8 accumulating / 0.55 distributing), momentum (1.5 / 0.67), smart money (2.0 / 0.4), buy pressure (1.6 / 0.5), volume-price divergence (1.7 / 0.55), holder conviction (1.3 / 0.8). The card shows each step of the update chain with colored arrows. Combined LR > 3.0 = strong multi-signal confirmation. LR < 0.3 = strong negative convergence.
Historical frequency anchors for event categories. Used as the Bayesian prior when a sector pattern matches the market question. Examples: incumbent re-election 60%, FDA Phase 3 approval 85%, recession probability 15%, fed rate cut 40%, ceasefire/peace deal 25%, beat economic estimate 52%. When the market price deviates more than 20% from the base rate, a BASE_RATE_NEGLECT warning fires -- the crowd may be ignoring statistical history.
Flags 5 psychological traps that distort market pricing. Each bias gets a severity badge (HIGH / MOD / LOW) and actionable advice:
When 2 or more HIGH-severity flags appear on a market, treat it as a strong caution signal.
AI-generated market intelligence cards. Click the Packs tab in the ALPHA panel to generate a pack of 5 cards on demand.
| Rarity | Quality Score | Multiplier |
|---|---|---|
| Common | < 8 | 1x |
| Uncommon | 8-13 | 1.5x |
| Rare | 14-19 | 2x |
| Legendary | 20+ | 3x |
Quality score = (signal count * 2) + min(10, |edge|) + min(5, kelly/2). Better AI insight = higher rarity. No luck involved.
Each card shows: market question, sector tag, side (YES/NO), entry price, payout multiplier, conviction (1-5 stars), rarity tier, 5-column quant grid (price, fair value, edge %, Kelly %, MC path %), signal badges (MOMENTUM, SMART $, BUY PRESSURE, HOLDERS, VOLUME, WHALE, EDGE, EXPIRING), volume and liquidity stats. Zero AI API cost -- all scoring is deterministic math from Polymarket data.
Foresight simulates parallel futures for the most tradeable prediction markets. Access via the FORESIGHT tab in the ALPHA panel.
When terminal market data is available, Foresight compares its snapshot prices to live prices. Each market card shows price change (cents), and a CONFIRMING or DIVERGING badge indicating whether the live price movement aligns with the AI's directional call.

The Autopsy tab reverse-engineers any trader's strategy on a specific market. It answers: who is trading this market, what are they doing, and should you care?
When you select a market, two things happen automatically:
Click any card or row to deep dive into a wallet's full forensic profile.
Each card gets a tag based on what data sources it appears in and what behavior stands out:
| Tag | Meaning |
|---|---|
| HEDGE | Wallet has both buy and sell volume on this market -- could be arbitrage or position management |
| ACTIVE HOLDER | Appears in both whale trades and holder list -- large position AND still actively trading |
| TOP TRADER | Appears on the global PnL leaderboard -- proven profitable trader across Polymarket |
| WHALE | $5K+ total volume on this specific market |
| HOLDER | Holds YES or NO tokens but hasn't traded recently (passive conviction) |
| TRADER | Active on this market with moderate volume |
The server analyzes trade patterns and assigns one classification per wallet:
| Classification | How it's detected |
|---|---|
| SMART MONEY | 60%+ time-in-profit with disciplined entries (no price chasing). Consistent strategy |
| ACCUMULATOR | Trade size increasing over time while maintaining profitability. Building a large position |
| SNIPER | 5 or fewer trades, 60%+ time-in-profit. High-conviction entries with precise timing |
| ARBITRAGEUR | Bought both YES and NO sides with combined average below $1.00 -- locking in guaranteed profit from mispricing |
| BOT | Sub-minute or sub-2-minute average gap between trades. Algorithmic execution pattern |
| DCA | Very tight price variance across all trades. Systematic dollar-cost averaging |
| BAGHOLDER | Bought at increasingly higher prices and now underwater, or scaling into a losing position |
| RETAIL | No distinctive pattern. Mixed timing and results consistent with casual trading |
When you click into a wallet, the full forensic profile shows:
At the top: the market being analyzed, current market price, the wallet's dominant side (YES or NO), net share count, VWAP, and unrealized P&L in both percentage and dollar terms.
VWAP (Volume-Weighted Average Price) is the average price this wallet paid for their shares, weighted by trade size. If someone bought 100 shares at 40c and 200 shares at 50c, their VWAP is (100*0.40 + 200*0.50) / 300 = 46.7c. Compare VWAP to current price to see if the trader is winning or losing.
What percentage of time this wallet has been "in the money" since their first trade. Calculated by checking the price history at every data point after their first trade and comparing to their average entry. Higher = better timing. Below 30% = consistently underwater.
Detects if the wallet traded both YES and NO sides. If the combined average price (YES avg + NO avg) is below $1.00, the wallet is arbitraging -- they locked in a guaranteed profit regardless of outcome. The "edge" is 100% minus the combined average.
Analyzes the time gaps between consecutive trades. Sub-30-second average = BOT. Under 2 minutes = LIKELY BOT. Over 5 minutes = HUMAN. Between = MIXED. Shows both average and median gaps (median resists outliers).
Compares average trade size in the first half vs second half of the wallet's history. INCREASING = scaling up (building conviction or doubling down). DECREASING = scaling down (taking profit or losing confidence). FLAT = consistent sizing.
How the wallet's entry prices changed over time. CHASING HIGHER = buying at progressively worse prices (FOMO signal). DOLLAR COST AVG = very tight price variance across all trades (systematic). DISCIPLINED = varied prices but not trending (opportunistic entries).
Net position direction (YES or NO bias based on buy vs sell volume), VWAP, and unrealized P&L. Positive = currently winning. Negative = currently underwater.
After the rule-based classification, you can request a deeper AI analysis. This sends all 6 metrics to Gemini Flash, which produces a classification, confidence score (1-10), one-line summary, and risk factors. The AI can catch nuances the rules miss, like a sophisticated strategy disguised as retail behavior.
When a market is selected, the enrichment API cross-references price history, trades, holders, and open interest to produce 9 signal categories:
| Signal | What it tells you |
|---|---|
| Momentum | BULLISH/BEARISH/FLAT direction. 7d and 30d price changes. All-time high/low. Slope and acceleration |
| Volume Trend | Rising/falling/stable. Spike detection (3x+ average). Surge and decline ratios |
| Whale Sentiment | ACCUMULATING vs DISTRIBUTING. Net flow dollars. Buy/sell trade counts |
| Holder Conviction | HHI concentration index. Top 3 holder percentage. HIGH/MODERATE/LOW rating |
| Lifecycle | Market age, maturity stage, days to resolution, urgency (CRITICAL/HIGH/MODERATE/LOW) |
| Smart Money | Conviction score (1-10), directional edge signal, institutional flow indicators |
| Volume-Price Divergence | Compares 7d price change vs volume change. Flags: BEARISH_DIVERGENCE, SELLING_EXHAUSTION, BREAKOUT_BUILDING, CONFIRMED_RALLY |
| Buy Pressure Trend | Last 3 days buy/sell ratio vs prior 4 days. Flags: SURGING, BUILDING, FADING, COLLAPSING |
| Holder Rotation | Cross-references YES/NO holder balance with whale net flow. Flags: SMART_YES, SMART_NO, DIVERGENCE |
The CAL tab controls every quantitative parameter. Three presets:
Parameter groups: Monte Carlo (sim count, max days, vol fallback, Brownian multiplier), Kelly (strong/moderate/marginal thresholds), Momentum (slope, vol bounds), Volume (spike multiplier, ratios), Whales (min trade size, accumulation/distribution), Holders (HHI levels), AI (temperature, max tokens, model).
Per-sector overrides let you tune parameters differently for crypto vs politics vs sports. All settings persist to localStorage. Import/export as JSON.
The 3D surface visualizes the full order book as a terrain map. No synthetic noise. Every peak and valley comes from real order data.
Construction: 32 price bins x 16 depth layers. Each order contributes to nearby bins via Gaussian kernel (sigma=0.002, radius=12%). Cumulative slicing: Z=0 shows top 6% of book, Z=max shows everything.
Color encoding: Green = bid-dominant, Red = ask-dominant, Amber = neutral, Blue = deep liquidity layers. Height modulated by holder conviction (HHI) and whale pressure (net flow). Spread gap carved at market price. Liquidity wall pillars at top 3 concentration levels. Holder conviction pillars (YES/NO shares). Cost-to-move-5% markers.
Controls: Drag to rotate. Double-click to toggle auto-rotation. Touch supported.
