Two wallets drove $117,000 in cartel-arrest trading volume

Their roughly $172 combined loss concealed much larger individual gains and losses. Separate checks found no trading in two specified pre-announcement windows.

  4. What this calculation covers
  5. Evidence and corrections

Two wallets generated $117,153.35 in displayed trading volume across two cartel-arrest contracts while losing $171.71 combined in MSR’s original blockchain reconstruction. One lost roughly $33,751 and the other gained roughly $33,579. Their nearly offsetting results explain why the combined cost was small; they do not show that either wallet faced little individual risk. Original transaction reconstruction

The pair traded matching Yes and No shares. A complete pair covers both answers and has $1 of backing, so creating it and later returning it can add volume while leaving combined cash nearly unchanged. Money can also move from one member’s result to the other as the prices of the two outcomes change. Volume counts that activity; the final combined result measures what remained after the recorded flows.

Evidence explained

The two cash results almost canceled

Combined−$171.71$117,153.35 displayed volume
Work it through

−$33,750.93 + $33,579.22 = −$171.71

The combined cost is about 0.147% of displayed volume. Volume is cumulative trading activity, not starting capital.

Ten shared transactions supplied most of the original activity

The same wallets appeared on opposite sides of ten shared transactions in the Ricardo Ruiz Velasco and Juan Carlos Valencia González arrest markets. MSR checked all 28 executions against Polygon’s ledger. After removing the pair’s activity, only $410.95 and $704.62 of other trading remained in the two contracts. The original broader review covered 1,849 fills across eight markets and checked 668 transactions. Coverage and reconstruction

The $171.71 combined loss was about 0.147% of displayed volume, roughly 15 cents per $100 traded. That is a cash-cost-to-volume comparison, not a return on invested capital. It leaves peak positions and the amount each wallet needed outside the calculation.

Two announcement checks answer a separate timing question

Questions raised by security analyst Alex Goldenberg and newsletter author Matthew Wein prompted a separate review of law-enforcement disclosures. For the April 27, 2026 capture of Audias Flores-Silva, MSR used a Mexican federal security official’s 20:20:03 UTC post as the public disclosure and checked it against wire coverage. The contract recorded no trades in the preceding hour. Its largest trade over the preceding 24 hours was $28.40. April event and counting window

The first buy came ten minutes and seventeen seconds after the post. Eight trades totaling $585.61 moved the price from 34 to 99 cents during the disclosure hour. That is observed post-disclosure activity, rather than evidence of trading before the announcement.

The separate August test found no trades in four named markets between the prior day’s sealed indictments and the public announcement.

At disclosure, 490.23 Yes shares were outstanding with a then-current value of $74.49. Hypothetically buying all at that value and later receiving $1 per share would leave $415.74 before costs. MSR did not observe that trade. The largest actual gain by a pre-disclosure holder was $100.94, and the wallet had first appeared during the market’s opening week.

For the August 5 charges-and-rewards announcement, four named contracts recorded no trades between the prior day’s sealed indictments and the public announcement. The next 72 hours contained one $4.50 buy, placed more than an hour after the press conference began. Three subjects had already appeared in public reports; only one was a new disclosure in this comparison. These checks apply to the named markets and windows, rather than a general conclusion about insider trading. August event and limits

The pair recurred, but the later totals remain unreconciled

An August 27 update found the pair again after displayed volume in the Juan Reyes Mejía González market rose from roughly $200 to $33,300. It supplied 99.4% during a 189-second August 25 episode. MSR also found an earlier Hugo Gonzalo Mendoza Gaytan episode and a separate Eurovision market with $22,494.94 over 166 seconds. Later episodes

The name check distinguishes Juan Reyes, “R-1,” from Ramón Ángel Álvarez Ayala, reported as “El R1.” The Juan Reyes trades preceded the August 26 announcement by a day. MSR found no Juan Reyes-specific news in that trading window, which does not establish what the wallets knew or why they traded.

Work it through

−122.61 − 41.83 − 102.85 + 357.00 = +89.71 dollars

The first two rows total $117,069.56 in volume and −$164.44 cash, differing from the original reconstruction. Eurovision is outside this table.

The later API reconstruction gave $117,069.56 in volume and a $164.44 combined loss for the original two contracts, compared with $117,153.35 and $171.71 in the blockchain reconstruction. The reason for those differences remains unresolved. Neither set is silently substituted for the other. Across four cartel episodes, the later reconstruction showed a positive combined result of $89.71; that wider population cannot replace the original two-contract loss.

The recurring paired trades, the two announcement checks and the unresolved reconstruction differences are distinct findings. Keeping their markets, periods and measurement bases explicit preserves what each establishes without assigning controllers or trading purpose. Unresolved questions

Calculation details

The original review covered 1,849 fills across eight markets and checked 668 transactions. The pair appeared in 10 of one wallet’s 12 transactions across the original two contracts, whose displayed totals were about $61,000 and $59,000. Detailed acquisition and reconciliation procedures remain in MSR’s workpapers.

Correction record

Aug 26, 2026 — wording clarification. The word “manufactured” was removed from the headline and copy, which now describe the observed mechanics. Transaction counts, volume, net-cost figures and conclusion are unchanged. Section 06 summarizes the attribution scope. See the research archive.
Aug 26, 2026 — wording clarification. The headline and citation string changed from “no insider trading found” to “no pre-public trading found in two tested events”, matching the report’s two-event scope. Transaction counts, displayed volume and net-cost figures are unchanged. Section 06 summarizes the attribution scope. See the research archive.
