The Sharp Report: A Rolling Digest of Smart Money on Polymarket and Kalshi

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 when you sit down is narrow and specific: which markets did smart money actually touch while you were away, which wallets with a real track record added risk, where do several of them agree, and where is the same event 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 tracked 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?

The Sharp Report is a standing briefing assembled from feeds the rest of the product already computes. It is not a mailout and not a once-a-day snapshot: the page recompiles from live sources, refreshing while you have it open, and it is dated from the moment the report you are reading was actually built rather than from your clock. What makes it a digest is the framing, not a publishing schedule — everything in it is scoped to the last 24 hours of tracked activity, so it reads like the morning summary even when you open it at midnight.

Five blocks make up the page. At the top, the Master Wallet's last 24 hours: the tracked cohort's PnL, the dollar volume behind it, how many wallets are in the cohort, and the single best-performing sharp of the day. Then the biggest sharp entries, meaning the largest positions opened by tracked wallets in that window — entries only, because a sell is an exit and this section is about where money is being put. Then the markets where three or more tracked wallets hold the same outcome. Then insider signals, which are young wallets holding large, concentrated positions. Then the widest cross-exchange gaps, ranked by what survives of the gap after estimated round-trip costs.

Each block is a shortlist, not a firehose, and each links back to the tool where you can dig in: a wallet name opens that wallet's page, a market opens on the venue, an insider row carries its signal strength, a gap row shows both venues' prices side by side. The digest is the index; the deeper tools are the chapters.

One design rule is worth knowing before you rely on it. Every block is optional and every fallback is empty. If a source is down, that block simply does not render — the report never substitutes placeholder rows and never prints a count it did not actually measure. A short report means a quiet window or a cold source, never a padded one.

How does the Sharp Report decide what counts as a sharp move?

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. The entries block does not rank the whole market's activity by dollar size; it ranks the activity of the wallets that already earned a place in the tracked cohort. A large trade from an unproven account never enters the report at all, which is why a moderate position from a consistently accurate wallet can top a section that a louder trade does not appear in.

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. Kalshi enters the report only through the cross-exchange gap block, as a price on a market, never as a trader.

Insider signals are the report's way of marking positioning that looks unusual before it looks obvious: young wallets taking large, concentrated positions, scored for signal strength. The report labels that block exactly as it should be read — a statistical pattern worth a look, never an allegation about a person. The cross-exchange block is more mechanical: it lines up comparable outcomes on Polymarket and Kalshi and ranks them by what is left of the gap once estimated round-trip costs come out, so a wide sticker gap that fees would erase does not float to the top of your read.

How do you trade with the 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 blocks, 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. Open a sharp entry's market and check whether the price still sits near where the wallet entered, or run it through the Market Analyzer for prices, positioning, and the cross-book gap on one screen. Click an insider flag through to the wallet behind it and judge whether the pattern is convincing. For a gap, open Divergence and Arbitrage and confirm the two contracts really resolve on the same terms before you assume the difference 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 when you happen to open it. Star the wallets it surfaced onto your Watchlist with a note, and add Alerts rules on them so that, while you have a WhaleTracks tab open, their next entry or exit raises a browser notification instead of waiting for your next read of the digest. Keep the Live Feed open when you are actively trading a flagged market. And size every position yourself, with the calculator at /bankroll if it helps. The report can tell you a proven trader leaned into an outcome; it cannot tell you how much of your bankroll that is worth.

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 the window. Every block is scoped to the last 24 hours, so the report is a look backward by construction and it will not tell you about a move that happens after you close the tab. If your style is intraday or you are trading fast-resolving markets, the digest is your orientation and the Live Feed plus Alerts are what keep you current for the rest of the session. 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, which is why the exchange appears in this report only as a price. Cross-exchange gaps 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 third is completeness. Because a failed source drops its block rather than faking one, a thin report can mean a quiet 24 hours or a cold feed, and the page does not always distinguish the two for you. Read a missing section as missing information, not as an absence of activity.

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.
