The Sharp Report: A Daily Digest of Smart Money on Polymarket and Kalshi
One briefing that turns yesterday's sharp moves, insider flags, and cross-exchange divergences into a two-minute read.
How do you keep up with sharp money on Polymarket and Kalshi?
Prediction markets never close. Polymarket runs on-chain around the clock, and Kalshi lists hundreds of contracts across politics, economics, weather, and culture. By the time a retail trader notices that a market has moved from 40 cents to 60 cents, the sharp traders who pushed it are already positioned and often already trimming. Watching every market by hand, on two exchanges, in every timezone, is not a workflow. It is a full-time job that no one actually does well.
The deeper problem is signal buried in noise. A basic polymarket tracker or kalshi tracker that streams every fill gives you volume without meaning. Thousands of trades cross every hour, and the overwhelming majority carry no information. What you want to know each morning is narrow and specific: which markets did smart money actually touch while you slept, which wallets with a real track record added risk, and where the same event is priced differently on two exchanges. Everything else is just scroll.
The Sharp Report exists to answer exactly those questions and nothing else. Instead of asking you to babysit a Live Feed all day, it compresses the previous 24 hours of activity into a single briefing built around what sharp traders did, not what the crowd did. You read it once, you know where to look, and you get on with your day.
What is the Sharp Report daily digest?
The Sharp Report is a once-a-day briefing. Every morning it assembles four things and presents them in a format you can read in about two minutes. First, yesterday's biggest sharp moves: the markets where high-conviction, high-track-record trading meaningfully shifted the price. Second, new insider flags: fresh signals of unusually concentrated or well-timed positioning worth a second look. Third, the widest cross-exchange divergences: outcomes that Polymarket and Kalshi are pricing differently right now. Fourth, Master Wallet performance: how the wallets the platform tracks most closely actually did over the last day.
Each of the four sections is a shortlist, not a firehose. The digest does not try to show you everything that happened. It surfaces the handful of items that cleared a bar and links each one back to the tool where you can dig in. A sharp move links into the market's full history, an insider flag links into the wallet or flow behind it, and a divergence links into the Divergence & Arbitrage view so you can see both sides of the spread. The digest is the index; the deeper tools are the chapters.
It helps to remember what you are actually reading about. On both exchanges you are buying and selling shares in a specific outcome, and a share pays one dollar if that outcome happens and zero if it does not. So a market trading at 60 cents is a live, tradable price on a real event, and a sharp move from 45 to 60 is a statement that informed traders think that outcome became meaningfully more likely. The Sharp Report is a daily map of where those statements were loudest.
How does the Sharp Report find sharp moves and insider flags?
The engine underneath the digest is the Sharp Score, a rating that grades traders on the quality and consistency of their history rather than on a single lucky call. When the report ranks yesterday's moves, it is not ranking by dollar size alone. A large trade from an unproven account is noise; a moderate trade from a consistently accurate one is signal. Sharp moves are the markets where high-Sharp-Score activity did the pushing, which is why a quiet 8-cent shift can outrank a loud one that only the crowd was chasing.
Attribution works differently on each exchange, and the report is honest about that split. Polymarket settles on-chain, so wallet addresses and their positions are public. That is what makes a genuine polymarket whale tracker possible: the platform can follow specific wallets across markets, score them, and flag when a proven one loads up. Kalshi does not expose individual trader identities, so the report never names a person or pretends to. There it surfaces anonymous flow, meaning aggregate patterns in how contracts are being traded, and treats that flow as a signal in its own right without attaching it to any human.
Insider flags are the report's way of marking positioning that looks unusual before it looks obvious. Think sudden concentrated buying into a single outcome, conviction that runs ahead of the visible news, or a wallet quietly rebuilding a position it just closed. A flag is a prompt to investigate, not a verdict. The cross-exchange divergence section is more mechanical: it lines up comparable outcomes on Polymarket and Kalshi and ranks them by how far apart the two prices sit, so the widest, most actionable gaps float to the top of your morning read.
How do you trade with the daily digest?
Treat the Sharp Report as a shortlist that tells you where to spend your attention, not a set of orders to copy. Start your session with it. Read the four sections, then pick the two or three items that overlap with markets you already understand. Domain knowledge is your edge on top of the signal: a flagged move in an event you can reason about is worth ten in a market you would only be guessing at. The digest narrows the field from thousands of markets to a handful; you still choose which handful deserves your capital.
From there, go one level deeper before you act. Click a sharp move through to its full price history and check whether the high-Sharp-Score activity is still on the same side or has already reversed. Click an insider flag through to the wallet or the Kalshi flow behind it and judge whether the pattern is convincing. For a divergence, open the Divergence & Arbitrage view and confirm the two contracts really resolve the same way before you assume the gap is free money, because near-identical wording can still hide different settlement rules.
Then wire the report into the rest of the toolkit so you are not only reacting once a day. Set Alerts on the specific wallets or markets the digest surfaced, so if a Master Wallet adds to a position at noon you hear about it in real time instead of tomorrow morning. Keep the Live Feed open when you are actively trading a flagged market. And size every position yourself. The report can tell you a proven trader leaned into an outcome; it cannot tell you how much of your bankroll that is worth, and it should never set your size for you.
Is copy trading prediction markets profitable?
The honest answer is that copy trading prediction markets is not a guaranteed strategy, and any tool that tells you otherwise is selling you something. Following smart money can be a real edge, but the edge lives in how you use the information, not in mirroring fills. The Sharp Report is built around intelligence, not blind copying. It shows you what informed traders did so you can form your own view, apply your own knowledge of the event, and decide independently. A signal you understand is tradable; a signal you copy on faith is just someone else's trade with your money on it.
Every performance number in the product carries the same caveat, and it is not boilerplate. Master Wallet results and any backtested figures describe what happened in the past. Past performance does not guarantee future results, and simulated or hypothetical results are exactly that: hypothetical. A wallet with a strong record can be early, wrong, or trading on information you do not have and cannot replicate in time. Sharp traders are sharp because they are right more often than the crowd, not because they are right every time, and their losing days are part of the same record as their winning ones.
The realistic way to think about it is that the digest raises the average quality of the ideas you look at, and disciplined execution does the rest. Position sizing, resolution-rule checks, liquidity, and knowing when to pass all sit with you. No feature in the Sharp Report, and nothing on this platform, promises profit. What the report offers is a faster, better-filtered starting point than staring at raw order flow, and a repeatable way to spend your research time on the moves that actually carried information.
What are the limits of the Sharp Report?
The first limit is cadence. The Sharp Report is a daily digest, so by design it looks backward at the last 24 hours. It is not a real-time instrument, and it will not catch a move that happens two hours after it publishes. If your style is intraday or you are trading fast-resolving markets, the digest is your morning orientation, and the Live Feed plus Alerts are the tools that keep you current for the rest of the day. Use the report to decide what to watch, then let the real-time tools tell you when it moves.
The second limit is the ceiling on attribution itself. On Polymarket, wallet tracking is powerful but imperfect: sophisticated traders split activity across addresses, and a public position never tells you the private thesis, the hedge on another venue, or the exit plan behind it. On Kalshi there is no trader-level identity at all, so the report works from anonymous flow and deliberately stops short of naming anyone. Cross-exchange divergences carry their own trap, since two contracts that read alike can settle on different rules, and a gap that looks like arbitrage can be a genuine difference in what each market pays out.
The last thing to keep in front of you is what these instruments are. They are exchanges where you trade shares in outcomes, and a share pays one dollar if the outcome happens and nothing if it does not, which means every position can go to zero. Smart money can be wrong, thin markets can move against you on your own order, and no digest removes that risk. The Sharp Report is a research and monitoring tool that sharpens your inputs. The judgment, the sizing, and the decision to trade remain entirely yours.
