Smart Money Intelligence
The Polymarket Smart Money Index tells you what the sharpest traders are doing right now.
The PSMI is a proprietary 0–100 index built by Polycopy that measures the real-time activity and confidence of the top-performing wallets on Polymarket. It distills thousands of trading signals into a single, actionable number — so you can see at a glance whether smart money is buying aggressively, sitting on the sidelines, or moving to risk-off.

What is the PSMI?
A real-time pulse check on Polymarket's most successful traders.
Polymarket's prices tell you what the crowd believes. The PSMI tells you what the best performers within that crowd are actually doing with their money.
Polycopy's data warehouse continuously monitors 6,000+ of the top-performing wallets from the Polymarket leaderboard. The PSMI synthesizes their trading patterns into four signals — momentum, velocity, quality, and conviction — and outputs a single 0–100 score that updates every 30 minutes.
When the PSMI is high, top traders are actively buying with confidence. When it drops, they're pulling back, selling, or sitting on the sidelines. It's the difference between knowing what the market price is and knowing what the sharpest participants think about that price.
Why it matters
Market prices are efficient. But they don't tell you who's trading.
A 65¢ contract means something different when the best traders on the platform are aggressively buying versus when they're quietly selling. The PSMI captures that distinction.
Market price alone
Tells you the crowd's consensus probability. Efficient but anonymous — you don't know if the latest volume is from whales or retail, conviction buys or hedges.
PSMI + market price
Adds a layer of smart money intelligence. You see not just the price, but whether top performers are actively aligned with it, skeptical of it, or ignoring the market entirely.
The four signals
Four signals, one score.
The PSMI is built from four weighted signals (Momentum 40%, Velocity 25%, Quality 20%, Conviction 15%), each normalized to 0–100. Together they answer: how are the best traders behaving right now?
Momentum (40%)
Are profits accelerating?
Compares the daily P&L rate of the top 100 traders this week against their 30-day average. A score above 50 means profits are accelerating — top traders are earning faster than their recent baseline. Below 50 means deceleration. This uses a log scale, so the score responds smoothly to large swings.
Velocity (25%)
How actively are they trading?
Compares the 7-day daily trade frequency of the top 100 traders against their 30-day daily run-rate. A spike in velocity means top traders are placing more trades than usual — they see enough opportunity to deploy capital faster. Above 50 = more active than baseline.
Quality (20%)
What % of active traders are profitable?
Of the top 100 traders who were active in the last 7 days (placed at least one trade), what percentage are in profit? Inactive traders are excluded so the metric reflects current market skill, not stale data. When quality is high, success is broad-based — not concentrated in a few outliers.
Conviction (15%)
Are they buying or selling?
Measures the buy-to-sell ratio of the 30 most recent large trades on Polymarket (over a rolling 6-hour window). High conviction means large players are net buyers — they believe current prices undervalue outcomes. Low conviction (more sells than buys) indicates they're reducing exposure.
How it's calculated
From raw trades to a single number.
Each signal is independently normalized to 0–100, then combined into a weighted average. The result is a score that's comparable across time periods and market conditions.

PSMI
62
0–100
Each signal is normalized to 0–100, then combined using weights: Momentum (40%), Velocity (25%), Quality (20%), Conviction (15%). Momentum is weighted highest because profit acceleration is the strongest leading indicator of smart money confidence. A single signal spike can't dominate the score — it has to be confirmed by other signals to push the PSMI into extreme territory.
Reading the gauge
What different PSMI levels mean.
The PSMI ranges from 0 (extreme bearish/risk-off) to 100 (extreme bullish conviction). Here's how to interpret each zone.
80–100
Very Bullish
Top traders are buying aggressively with high conviction. Historically correlates with strong market moves.
60–79
Bullish
Smart money is net positive and active. Solid conditions but not extreme.
40–59
Neutral
Mixed signals. Top traders are neither strongly buying nor selling. Wait for confirmation.
20–39
Cautious
Smart money is pulling back. More selling than buying, or reduced activity overall.
0–19
Risk-Off
Extreme caution. Top traders are significantly reducing exposure. Rare but important.
The data warehouse
Why it matters where the data comes from.
The PSMI is only as good as the data behind it. Polycopy's warehouse tracks the right wallets and the right signals.
6,000+
top-performing wallets tracked from the Polymarket leaderboard
50+
market categories analyzed across politics, sports, crypto, and more
30min
refresh interval — the PSMI updates every half hour with fresh data
24/7
continuous monitoring of trade activity, positions, and P&L
The wallets in the data warehouse are selected from the Polymarket leaderboard based on realized performance — not just volume or activity. This means the PSMI reflects the behavior of traders who have actually demonstrated skill, not just noisy activity.
The warehouse captures data that the public Polymarket API doesn't expose: niche-level P&L, win rates per category, trade sizing patterns, and temporal activity trends. This proprietary data is what makes the PSMI possible.
How to use it
The PSMI is a compass, not a GPS.
It tells you the general direction smart money is moving. It does not tell you exactly which trade to make.
Market context
Use the PSMI alongside the Odds Tracker and market-specific data. A high PSMI during a major event (election, crypto event) is more actionable than during quiet periods.
Trend, not snapshot
A PSMI of 55 that's been rising for 3 days tells a different story than a 55 that just dropped from 75. Watch the direction as much as the number.
Combine with Copy Score
The PSMI tells you about market-wide smart money sentiment. Copy Score tells you about individual trade quality. Together they give you a fuller picture.
Practical example
You see a trade with a Copy Score of 78 (strong). You check the PSMI and it's at 72 and rising — top traders are actively buying across the platform. This is a higher-confidence setup than seeing the same Copy Score during a PSMI of 25 (risk-off). The PSMI doesn't change the trade quality, but it tells you the environment that trade is happening in.
PSMI vs market price
What the PSMI adds that prices don't.
Market prices reflect consensus. The PSMI reveals whether the most successful participants agree with that consensus or are positioning against it.
Smart money is aggressively positioning despite stable prices — they may see something the market hasn't priced in yet.
PSMI confirms the rally — top traders are aligned with the price move. Higher confidence in the trend.
Divergence: prices rising but smart money is pulling back. The rally may lack substance.
Neutral on both sides. No strong signal from smart money — patience may be warranted.
Key insight
The most interesting PSMI readings are divergences — when the PSMI disagrees with market prices. A high PSMI during a falling market suggests smart money sees value. A low PSMI during a rally suggests the move may not be sustainable. These divergences are where the PSMI adds the most unique information.
Limitations
What the PSMI cannot do.
Transparency about limitations is part of the design.
Not predictive
The PSMI describes current smart money behavior, not future price movements. Even top traders get it wrong. Past patterns don't guarantee future outcomes.
Aggregate, not specific
The PSMI is a market-wide signal. It doesn't tell you which specific market smart money is targeting. Use it with market-specific analysis for that.
Lag exists
The PSMI updates every 30 minutes. In fast-moving markets, the signal may lag the actual behavior by up to half an hour.
Not a trading recommendation
Like Copy Score, the PSMI is an indicator. It helps you see more clearly, but it does not tell you to buy or sell. Always use your own judgment.

Risk disclaimer
Trading carries real risk.
The PSMI and supporting signals are informational tools. They help you think more clearly about market conditions, but they do not guarantee performance.
Past performance of tracked wallets does not guarantee future results. Even the most successful traders experience losing streaks.
The PSMI is an aggregate indicator. Individual market outcomes may diverge significantly from the overall smart money trend.
Polycopy does not provide financial advice. Use the PSMI as context for your own decision-making, not as instruction.
