Market Trust diligence packet
Will New York City FC win on 2026-05-06?
2 of 6 pillars measured, 2 modeled by fixed rules, 2 not assessed. Certainty reflects how much of this market we measured, not how good the market is.
One of four bands, strongest warning on the right
Too much of the trading came from wallets we cannot yet identify, so participant-flow coverage is uncertain.
Use only as a review target. Current-card issues must clear before this price is used as evidence.

Convexly rates this polymarket market "Will New York City FC win on 2026-05-06?" as Do not cite. Use only as a review target. Current-card issues must clear before this price is used as evidence. Caveat to carry: Too much participant flow is unknown while participant-flow coverage is still pending. This is market diligence, not a trading instruction or proof that the market probability is correct.

Resolution rule
In the upcoming game, scheduled for May 6, 2026 If New York City FC wins, this market will resolve to "Yes". Otherwise, this market will resolve to "No". If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, this market will resolve "No". This market refers only to the outcome within the first 90 minutes of regular play plus stoppage time. The primary resolution source for this market is the official statistics of the event as recognized by the governing body or event organizers. However, if the governing body or event organizers have not published final match statistics within 2 hours after the event's conclusion, a consensus of credible reporting may be used instead.
Rules as stated by the venue, reproduced verbatim; not independently reviewed or endorsed by Convexly.

Audit chainReceipt and verification
Convexly stores the card payload, removes the row_hash field, canonicalizes the remaining JSON, and recomputes the SHA-256 hash. This is the bridge from a readable verdict to a buyer-reviewable audit chain.

Verdict hashImmutable verdict archive
This verdict is archived as a canonical JSON object with a SHA-256 content hash. The hashed payload carries the methodology version (market_trust_card_v0_2), the canary_preview label, and a fixed boundary statement; none of them can be removed without changing the digest.

How to verify this hash
- Fetch the canonical archive bytes: https://www.convexly.app/api/market-trust/v0.2/0x07aa441123aa310a7949312c6233f1d291bd78e1fe5da57c94fa1f4d03c40a4c/archive?venue=polymarket&format=canonical
- Recompute the digest locally, for example: curl -s "https://www.convexly.app/api/market-trust/v0.2/0x07aa441123aa310a7949312c6233f1d291bd78e1fe5da57c94fa1f4d03c40a4c/archive?venue=polymarket&format=canonical" | shasum -a 256
- Compare your digest to archive_sha256 in the JSON response at https://www.convexly.app/api/market-trust/v0.2/0x07aa441123aa310a7949312c6233f1d291bd78e1fe5da57c94fa1f4d03c40a4c/archive?venue=polymarket. Matching digests mean the archived verdict content is byte-for-byte unchanged.
- Cross-check card_row_hash against the stored full-card receipt at https://www.convexly.app/api/market-trust/v0.2/0x07aa441123aa310a7949312c6233f1d291bd78e1fe5da57c94fa1f4d03c40a4c/verify?venue=polymarket.
Stored v0.2 cards are frozen scorecards: a re-score inserts a new row with a new card_id and records the prior receipt in previous_row_hash, and the filed calibration design binds Convexly to never mutate frozen card-time rows. The archive is a deterministic serialization of one stored row, so the same row always reproduces the same archive_sha256.

Market Fitness - pre-trade diligence (experimental)
4 of 6 diagnostics have a derivable observable on this stored card; 2 are insufficient_data. An insufficient_data row means the card lacks that input, not that the check passed.
Depth and slippage at size is a Researcher feature.
The resolution-reliability, manipulation, and basis-risk reads below are open. To see the fill cost at $100 / $1k / $10k and the executability detail, upgrade to Researcher.
Depth durability
heuristic
insufficient data
At-size depth and slippage detail is a Researcher feature. Upgrade at /pricing to see fill cost at size.
Observable: Executability pillar: worse-of(top-of-book spread, modeled price impact) from the latest inspected orderbook snapshot at 2026-08-08T07:30:10.921+00:00
Caveats: derived from a single orderbook snapshot; durability across time is not yet measured on this card; descriptive diagnostic from operator-set scoring that is not calibrated; no interval exists for this value, so none is shown rather than fabricated; gated detail requires researcher
Spread and price impact
heuristic
insufficient data
At-size depth and slippage detail is a Researcher feature. Upgrade at /pricing to see fill cost at size.
Observable: Top-of-book spread (price points) and modeled price impact for a fixed notional, from the latest inspected orderbook snapshot
Caveats: spread cost over a holding period is not modeled; this is a single-snapshot read; descriptive diagnostic from operator-set scoring that is not calibrated; no interval exists for this value, so none is shown rather than fabricated; gated detail requires researcher
Time to resolution
insufficient data
insufficient data
Venue lifecycle status on the card: active. No end date is stored.
Observable: Venue-supplied market end date or close time stored on the card
Missing input: The v0.2 card schema does not store an end date or close time, so time to resolution cannot be derived from this card.
Resolution reliability
heuristic
70 / 100 (descriptive)
Resolution source and rule text are present but not independently reviewed. Resolution rule text is stored on the card.
Observable: Resolution reliability pillar: review of the resolution source (https://www.mlssoccer.com/schedule/scores) and stored resolution rule text
Caveats: resolved-outcome dispute history is not joined on this card; the read covers resolution source and rule text only; descriptive diagnostic from operator-set scoring that is not calibrated; no interval exists for this value, so none is shown rather than fabricated
Concentration exposure
insufficient data
insufficient data
Participant-flow screens flagged concentration, unknown-flow, or low-edge-flow conditions for review.
Observable: Participant-flow concentration from the card's integrity screen: top account flow share, unknown flow share, scored notional share
Missing input: Participant-flow concentration is not measured on this card (no scored participant rollup or no top-account flow share).
Basis-risk note
descriptive
structural note
This market settles as a binary event contract: it pays a fixed amount on one discrete resolution. Offsetting a continuous exposure with a binary payoff leaves residual basis risk by construction, and binary payoffs will generally fail the ASC 815 80-125% dollar-offset band used for hedge-accounting treatment, so a position that works as an economic offset can still be carried as mark-to-market P&L. This is a structural description of the contract type, not a statement about any party's exposure.
Observable: Contract payoff structure (binary event contract) and the resolution rule text stored on the card
Caveats: structural description of the contract type, not accounting or legal advice
Published deliberately as a component table with no single combined number. Read each component against the observable it derives from; an insufficient_data row means the stored card lacks that input, not that the check passed.
These diagnostics describe observable market-quality measurements for one market. They are not investment advice, not a trading instruction, not a recommendation to take or offset any exposure with this or any market, and not a statement about any person or their positions.

Live market integrity read is a Trader feature
Trader ($499/mo) unlocks an on-demand participation-concentration read on any market — HHI of wallet volume shares with a confidence interval on every estimate, plus a round-trip self-churn share, computed live from the current flow tape. Descriptive structure with receipts, not a manipulation call.
Boundary of the packet
This packet is market diligence, not investment advice, not a claim of absolute truth, and not proof that any trader should buy or sell. It answers whether the market price has enough substrate to cite, monitor, discount, or ignore with receipts attached.
