A 28,000-set round trip between Car and his declared alt. A second account that repeatedly crossed his orders. The orders, signatures and money movements are now checked against primary chain records.

On November 25, 2025, Car’s main wallet and b4k9xj2wh2 matched complementary orders on Israel strike on the West Bank by December 31? They opened 28,000 complete YES/NO sets and closed all 28,000 just 404 seconds later.
| Leg | UTC | Car | b4k9xj2wh2 | Combined |
|---|---|---|---|---|
| Open / mint | 15:32:53 | 9,240 USDC.e paid 28,000 YES received | 18,760 USDC.e paid 28,000 NO received | 28,000 USDC.e locked |
| Close / merge | 15:39:37 | 8,400 USDC.e received 28,000 YES sold | 19,600 USDC.e received 28,000 NO sold | 28,000 USDC.e released |
| Net | 6m 44s | −840 USDC.e | +840 USDC.e | 0 USDC.e Both outcome holdings unchanged |
56,000 USDC.e is the sum of opening and closing collateral turnover. It counts each economic leg once. It is not a claim that a volume or rewards counter credited that amount.
Both successful receipts contain only their two orders. We independently rebuilt all four EIP-712 order digests, matched them to the emitted hashes and recovered Car’s 1f64… and b4’s eff41… keys. Twelve archival balance reads confirm their cash and both outcome holdings before the opening transaction and after the closing transaction. An independent transfer-window check covers the holding interval.
Car publicly identified b4 as his alt in February and September 2026. Those admissions postdate these trades. A separately verified 11 USDC.e setup payment, actually signed by Car on April 1, 2025, establishes their funding relationship before the November trades.

Its official profile was created on September 12, 2025 at 18:10:13.056876 UTC. At 18:11:59, proposer key 0xbbcab…41f90 (W6) sent it 1,000 USDC.e. That was 105.943124 seconds after profile creation. At 18:43:03, W6 sent another 2,000 USDC.e, bringing the funding to 3,000 USDC.e. The refill arrived just before the final five cycles.
Eight days earlier, Car had authorized 700 USDC.e to W6. All three actual funding authorizations are independently recovered, including the 2,000 USDC.e refill. These funding links do not establish that the same specific 700 funded the later 1,000 payment.
From 18:14:09 to 18:47:13 UTC, CarComboCup and Car completed 12 mint-and-merge round trips across three markets. All 24 successful transactions contain only their two orders. All 48 actual order signatures recover Car’s known key and CarComboCup’s 0x44fceb465cf1ced769c3a50d5b511095cdae4f57.
Each paired opening and closing contribution cancels the new outcome inventory. The trades shifted 1,601.50 USDC.e net from CarComboCup to Car. The account’s cash ledger closes: 0 + 3,000 funding − 1,601.50 trading cost = 1,398.50 USDC.e remaining. Before the refill it held 478.50; immediately afterward, 2,478.50. Archived balances confirm these figures. The bounded cash and exchange-fill queries cover 18:01:29–18:58:31 UTC and contain exactly the two funding credits and the same 24 trading transactions.
CarComboCup does not appear in the eight-wallet collection Car disclosed. Its human ownership remains unresolved. Repeated trades and funding support a substantial network link; they do not by themselves identify the person controlling its key.

What these transactions establish.
The b4 case establishes a concrete self-matched round trip between Car and an account he publicly declared as his alt. This is a strong self-dealing and wash-trading indicator: it created settled turnover while restoring the group’s cash and market exposure, apart from an internal 840 USDC.e shift.
Polymarket’s archived 2025 terms, updated August 26, already prohibited wash trading, fictitious trades and arranged transactions without genuine competition. Identical archived text before and after both trading dates confirms the historical rule context. The wash-trading clause turns on knowingly avoiding genuine market risk.

The primary records establish the self-matches and the cash flows. Subjective purpose, CarComboCup’s human ownership, rewards capture and a formal rules decision remain open. The original public dataset supplied the leads; this report independently verifies them rather than claiming first discovery. Neither case identifies the DebugBear drainer.
