Research Archive & Corrections.
Published research, material revisions, and corrections behind MSR Decode’s July 2026 Polymarket wallet forensics, dated and permanently accessible. The recurring monthly leaderboard audit and forward-tested ledger described below were retired on August 26, 2026; material corrections were recorded here as they were identified, dated, without altering the original entry. Nothing below is edited after the fact — corrections are appended, never erased.
30 wallets audited · 4 profit claims checked · 1 confirmed · 3 refuted · 16 items in our public register of unreconciled numbers and corrections
Each figure is computed from a published artifact rather than kept as a tally, and the pre-publish gate refuses this page if the two disagree: the scorecard, the weather-bot reconciliation, the BNB ledger, and the register. Two of the sixteen are resolved and stay listed; entries leave that file by being reconciled, never by being deleted. Not every one is a mistake of ours — some are numbers we rely on that we cannot reconcile.

What actually went live this cycle, in order.
The Leaderboard Scorecard — July 2026 cycle
Audited Polymarket’s top 25 wallets by 30-day profit. 10 of 25 earned a Real-edge, copyable rating at launch; the dated Jul 16 re-stamp entry in Section 02 below moved four of them to Insufficient evidence, and the standing count is 6 of 25. Re-run monthly. Read the scorecard →
Reconstruction Workpaper published — methodology v1 frozen
Every per-wallet reconstruction error published, spec recon-error-v1 frozen the same day. Headline: median gap 5.1 points, aggregate 98.7% of displayed dollars, across the 10 wallets in the structural set — and 15 of 25 refused rather than guessed. Read the workpaper →
Two case files published
The Leaderboard Autopsy — a top wallet’s celebrated “edge” decomposed, fill by fill, into redemption arbitrage a copier could never have captured. Sample Decode: myzbsq — a $249K → $1.22M World Cup bet reconstructed to 99.6% of Polymarket’s displayed profit (MSR’s cleanest case, a closed single-market wallet) and classified a one-shot, not a repeatable edge. Autopsy → · myzbsq →
Evidence-confidence gate shipped
A second, independent label — Verified / Provisional / Insufficient data — grades fetch completeness separately from the six-way verdict, so a copyable stamp can no longer imply a complete fetch it doesn’t have. Of the 25 as shipped: 6 Verified, 4 Provisional, 15 Insufficient data. (Correction, Aug 4, 2026: three of those labels have moved to Provisional under the gate’s own rule — the split now reads 3 / 7 / 15; see U12 below.) See the rule →
Prospective Copyability Ledger launched
Every Real-edge verdict now gets one ledger entry: follower-accessible prices frozen at entry, outcomes published at 24h / 7d / 30d — gains and losses alike. Cohort 1 froze 6 entries on Jul 19; the d7 checkpoint published on schedule Jul 26, 2026, and the d30 checkpoint followed Aug 19, 2026, about 1.2 days late — cohort 1’s ledger is now complete. Read the ledger →
Case file: the BNB 5-minute wallet
The viral wallet that turned $449K into $1.37M in 3.1 hours, reconstructed to the cent: net realized $917,311.53, matching the viral “~$917k” claim to within $311.53. Read the case →
Method report: an endpoint default that undercounted fills, corrected
An integrity check initially flagged three top-leaderboard wallets for $926,462.58 of profit on positions they never paid for. Polymarket’s /trades endpoint defaults to takerOnly=true, so it silently returns only part of a wallet’s fills — and in markets with no order book that hides nearly all of them. Re-fetched properly, the 50 largest flagged markets within each of the three wallets — 150 of the 4,725 flagged, not a pooled ranking — reconciled 150 of 150. All three traders were ordinary. Read the corrected method report →
The d7 ledger checkpoint published on schedule
Cohort 1’s 7-day outcome came back identical to the 24-hour marks: hot2trot $1,475 (+47.5%), highnetworth $1,665 (+66.5%) on a simulated $1,000 each, the other four flat because they had nothing a follower could buy. Every copyable position had already resolved by the roughly 26-hour checkpoint (computed 2h late per the ledger) — so the copyable window on this cohort was days shorter than a week; this checkpoint bounds the window rather than measuring it, a limitation of the checkpoint interval published as one. Read the checkpoint →
Two forensic notes published
NYC Council opened a public marketing-practices review of four prediction-market platforms; MSR Decode has not independently reconstructed any specific wallet, trade or video named in the reporting that preceded it. Separately, a creator’s viral Polymarket win was reported staged, with more than 50 real accounts said to have made the same bet and lost — rebuilt fill by fill: 48 wallets, none profited. Note 01 → · Note 02 →
Forensic Note 03: a federal insider-trading complaint, reconciled
The CFTC’s complaint against Gannon Van Dyke states its figures as approximations and floors. MSR Decode pulled the named wallet’s complete Polymarket record: the approximations hold, the floors are exceeded, and press-reported prosecution figures reproduce to the dollar. Read the note →
The d30 ledger checkpoint completes cohort 1
Cohort 1’s 30-day outcome matches the 7-day mark exactly: hot2trot $1,475 (+47.5%), highnetworth $1,665 (+66.5%) on a simulated $1,000 each, the other four flat — no copyable position remained open past the 7-day mark to move. Computed about 1.2 days late (see the ledger for why). All three checkpoints (24h / 7d / 30d) are now on the record for every cohort-1 entry. Read the checkpoint →
Program-status update: the July leaderboard program moved to historical status
MSR Decode broadened from a wallet-copyability research program into a general independent prediction-market forensic research desk. As part of that repositioning: the July 2026 Scorecard remains frozen and public; the completed Prospective Ledger (cohort 1) remains public; the wallet-reconstruction Workpaper remains public; MSR Decode is not currently running a recurring monthly Top-25 cycle. This supersedes, from this date forward, the recurring-cycle commitment in Section 03 below (“Monthly scorecard refresh”) and the dataset/API concept referenced there (“Dataset access on request”) — that commercial dataset/API concept is not an active MSR Decode offering; current commissioned services are described on the Capabilities page. Both original entries remain visible below because this archive is append-only. Read the current investigative standard →
Corrections & refusals
Material corrections, dated and append-only, and the wallets refused a rating because the data didn’t support one.
/trades endpoint defaults to takerOnly=true and silently returns only part of a wallet’s fills, which in markets with no order book hides nearly all of them. Re-fetched per-market from /activity, the 50 largest flagged markets within each of the three wallets — 150 of the 4,725 flagged, not a pooled ranking — reconciled 150 of 150, backed by $1,361,899.05 of real buying across those markets. All three traders were ordinary. Read the corrected method report →enable_order_book: false and are matched by Polymarket’s own operator, not an order book. The purchases and reconciliation are unchanged; the mechanism described was not accurate, and was corrected in four places, including a filed CFTC comment that cannot itself be amended.

Only commitments already on the record — nothing new promised here. Both lines below were superseded Aug 26, 2026 by the program-status update in Section 01 above; they are preserved here, not deleted, because this archive is append-only.
Monthly scorecard refresh. The top-25 audit re-runs monthly; the next cycle’s accuracy rule (Superseded Aug 26, 2026 — no recurring monthly cycle is currently running; see the program-status update above. Scorecard →recon-error-v2) is already pre-registered and frozen ahead of the results.Dataset access on request. Structured historical-and-prospective verdicts, including the append-only ledger, remain under evaluation for research, risk & compliance teams — ask about intended use.Superseded Aug 26, 2026 — this dataset/API concept is not an active MSR Decode offering; current commissioned services are described on the Capabilities page.

Nothing above is a new promise. Every line in this section is a date or a policy already published on the page it links to; this page adds no figure and no commitment that didn’t already exist there.
