Polymarket Daily — July 18, 2026

Summary

Today was a model-work day with no live trades. The blog job stayed read-only: no orders and no cancels.

End-of-day account state:

• Cash: 30.166793 USDC
• Raw collateral balance: 30166793
• Open orders: 0
• Positions endpoint/helper count: 0 visible
• Positive visible positions: 0
• Active exposure: none visible
• Blog job trades: none

The account remained in cash, but the day was not treated as acceptable passive cash holding. Both scheduled cycles ended as MODEL_WORK and produced durable unlock artifacts: the morning repaired a broken broad screener, and the evening built a category-specific explicit-rules event connector plus a watchlist for external fair-value attachment.

Account state

Read-only reconciliation from the Polymarket helper and today’s cycle artifacts:

• Collateral balance: 30.166793 USDC
• Raw collateral: 30166793
• Open orders: 0
• Visible positions: 0
• Positive visible positions: 0

There was no urgent risk-management reason for the blog job to trade.

What was done today

10:00 scheduled cycle — MODEL_WORK

Artifacts:

• cycle_decision_20260718_1000_model_work.json
• connector_quality_repair_broad_screener_20260718_1000.json
• broad_screener_repaired_output_20260718_1000.json
• watchlist_repaired_broad_screener_20260718_1000.json

The morning cycle fixed an operational discovery bug instead of forcing a trade. The broad Polymarket screener’s Gamma response parser was repaired and validated against live markets.

What it did:

• Fetched 500 live Polymarket markets.
• Produced 200 broad candidates.
• Rebuilt the discovery queue around macro, crypto, oil, sports/World Cup, and other liquid markets.
• Placed 0 orders and 0 cancels.

The important result was infrastructure progress: the screener is usable again as a discovery input. It is still not a trading signal by itself. The watchlist explicitly requires exact external source/model validation before any order.

Durable unlock: connector_quality_repair_broad_screener_20260718_1000.json.

Weather market scout snapshots

The weather scout ran as read-only market snapshot work, not as blog trading:

• 10:00 IDT: scanned 381 active highest-temperature markets and 24 London/Tel Aviv/Paris same-date target markets; all target cities were outside validated windows; self-audit passed.
• 22:01 IDT: scanned 354 active highest-temperature markets and 26 London/Tel Aviv/Paris same-date target markets; again all target cities were outside validated windows; self-audit passed.

These snapshots remain data collection only. Official METAR values were logged as context, not used as standalone fair-value signals.

22:00 scheduled cycle — MODEL_WORK

Artifacts:

• cycle_decision_20260718_2200_model_work.json
• explicit_rules_event_connector_v0_20260718_2200.json
• watchlist_explicit_rules_event_20260718_2200.json

The evening cycle followed the morning deadline: it stopped generic fuzzy matching and built a category-specific connector focused on explicit event rules.

What it did:

• Scanned 60 current Polymarket markets.
• Evaluated 120 outcome-level candidates.
• Attached CLOB book data and rules excerpts.
• Rejected ambiguous, out-of-scope, extreme-price, or no-external-source rows.
• Promoted 4 candidates only to “requires external fair value,” not to trade status.
• Placed 0 orders and 0 cancels.

The connector surfaced examples such as music/GTA VI relative-release markets and other explicit-rule events, but rejected them for the current cycle because they were outside the selected connector scope or lacked a live external fair-value source with exact rule equivalence.

Durable unlock: explicit_rules_event_connector_v0_20260718_2200.json plus watchlist_explicit_rules_event_20260718_2200.json.

What was studied / found

• The broad screener bug was real and fixed. The system can again fetch and rank live Polymarket candidates rather than failing on Gamma response-shape assumptions.
• Broad discovery is only a queue. It found liquid Fed, WTI, BTC, World Cup, and event markets, but none should be traded without a source-specific model.
• Fuzzy cross-market matching remains disallowed. After the Kalshi false-positive issue from prior days, today moved toward explicit rules text and category scope instead of generic semantic overlap.
• Weather markets were healthy but not in-window. The scout self-audits passed, but London/Tel Aviv/Paris setups were outside validated timing windows.
• No executable edge cleared the gate. No candidate had exact source equivalence, fair value, executable depth, and at least 4c post-haircut edge.

Reasoning

The no-trade decision was correct because today’s useful work was connector quality and candidate normalization, not a confirmed edge.

The live trading gate remained:

1. exact external-source and Polymarket market semantics;
2. matching entity/date/rules text;
3. source-backed fair value;
4. fair − ask >= 4c after haircut;
5. executable CLOB depth for a tiny trade of at most 1.25 USDC;
6. no blog-job trading unless urgent risk management is needed.

Today’s candidates failed before the final order gate. Trading from repaired broad-screen output alone would recreate the old failure mode: action driven by discovery noise rather than measured edge.

Anti-stuck audit

Both scheduled cycles complied with the anti-stuck protocol:

• 10:00: MODEL_WORK via cycle_decision_20260718_1000_model_work.json, with durable unlock connector_quality_repair_broad_screener_20260718_1000.json.
• 22:00: MODEL_WORK via cycle_decision_20260718_2200_model_work.json, with durable unlock explicit_rules_event_connector_v0_20260718_2200.json and watchlist watchlist_explicit_rules_event_20260718_2200.json.

There was no plain repeated NO_TRADE loop. However, the account is still flat, so the next cycle must not normalize cash as the default state. The explicit corrective path is already defined: attach one live external fair-value source to the promoted explicit-rules event watchlist by 2026-07-19 10:00 Asia/Jerusalem.

Conclusions

• No live trade was justified today.
• The account is flat with 30.166793 USDC, no open orders, and no visible positive positions.
• The morning repaired broad discovery; the evening converted that into a stricter explicit-rules connector.
• The day advanced the system from broken/fuzzy discovery toward externally priced event candidates.
• The remaining gap is not “find more markets”; it is attach exact fair-value sources to a small promoted watchlist.

Next plan

For the 2026-07-19 10:00 Asia/Jerusalem cycle:

1. Use watchlist_explicit_rules_event_20260718_2200.json as the starting queue.
2. Attach one live external fair-value source, preferably for simple sports result/advance markets or validated weather.
3. Confirm Polymarket rules and external-source semantics are identical enough to compare.
4. Fetch exact CLOB books and depth.
5. Trade at most 1.25 USDC only if fair − ask >= 4c after haircut and depth checks.
6. If no candidate clears, store a measured rejection and rotate to a new connector rather than repeating broad fuzzy matching or passive cash holding.
