5 scheduled closes did not land — the daily index publish was due at 10:37 UTC on 2026-09-23 and the newest print on file is still 2026-09-22. The reading below is carried forward from that date and does not describe today.
Readings below are the last that settled; none has been carried forward, restated or interpolated to cover the gap. Every row states its own date and wears its own age. How the desk publishes
W.E.T. Artist Culture Index 6mo
v1StandingExperimentalStanding32 input(s) were quarantined by sentinel/v1 before this close and are excluded from the reading above.
- The "artist" axis stops appearing in culture titles: the selector then admits fewer than 6 markets and the index prints nothing rather than a level over a roster that no longer states the thesis.
- Weight coverage falls below the declared floor of 95%, at which point the published state is insufficient_data and no value is printed — never a value carried forward from the last close that had one.
- A published axis starts framing this board. No axis frames a majority of it today (polarity frames 0 of 6, severity frames 0 of 6, threshold frames 0 of 6), and that measurement is what put this worldview on a side-symmetric lens; a composition whose sides become readable is a different index and belongs to a successor spec rather than to an edit of this one.
How this reading was constructed (7)
- universe: resolved by universe/v1 over 9403 candidate canonical event(s) from the `tape-text` source (
${m.title ?? ''}${m.marketRef}), admitting 75. Rejections by reason: keyword-miss 9310, horizon-outside-window 18. - universe: the declared 60–200d horizon window (axis 8) was APPLIED and removed 18 event(s) that every other selector admitted. A member resolving outside the window this index publishes is not a member of this index's horizon, whatever else it is.
- universe: 9310 event(s) missed the keyword screen on the `tape-text` source, which carries
${m.title ?? ''}${m.marketRef}and NOT the venue subtitle, tag or series the nomination pool sees. That count is the UPPER BOUND on what the richer string could have added here; it is published rather than estimated, because the tape cannot supply the text that would settle it. - eligibility: 57 of 75 admitted event(s) left the roster on the spec's own declared eligibility (minVolume 250, maxSpread 0.1, price 0.02-0.98) — by reason: price-below-floor 55, below-min-volume 2. An ineligible market is out of the universe; a member the close could not price stays in it and is counted against κ.
- orientation: the declared `polarity` framing axis (§3.3) was re-read on this tape and took NO force [undetermined:coverage], framing 0 of 18 members and holding 0 of them NO. The declared polarity axis frames 0 of 18 members (0%), under the published 50% bar, so it takes no force today and no member is flipped by it. An axis that frames a corner of the board would state a direction for members it never read. This is the spec's own invalidation condition, measured rather than assumed. The axis is re-read at every close rather than frozen into a declared side table, so a roster whose contracts resolve and are replaced is oriented by the rule this spec published rather than by one evening's reading of it (cultivation-orientation/v3).
- orientation: because the declared `polarity` axis took no force today, every member not named in `sideRules.declaredSides` and not matched by a keyword list is held on the venue's own YES framing. That reads the board's LISTING CONVENTION rather than this index's thesis, and it is the state the spec's own invalidation conditions name — published here rather than left to look like a decision the axis made.
- no published document file was found for this spec, so the byte comparison had nothing to compare against and only the recompile legs ran. The whitepaper is compiled per request by /methodology/<slug>, which is a publication lag rather than a ledger fault — but the ABSENCE is published here, because an unsupplied optional parameter is invisible on the row and that invisibility is what let this leg go unrun.
The governed close level above is divisor-chained: it tracks how the desk’s reading of this perspective has moved since 2026-08-14, and it survives a roster change because the divisor absorbs it. It is not a basket total return.
The basket total return below is a position book: it holds a fixed set of contracts from its own inception and reports what that book did, marks and settlements included. A roster change starts a new book rather than being absorbed.
They share a base of 1,000 and nothing else. Expect them to differ, and read the one that answers your question — the chained level for “where does this perspective stand”, the book for “what would holding it have done”.

Equal notional from each holding’s inception mark, re-marked at the two-sided mid. Percentages only, size-blind — never a cash figure and never a performance claim.
Cost to cross is the weighted half-spread at the touch on the newest mark tape: what entering at the quote rather than the midpoint would have cost. It is the price of the FIRST unit and says nothing about the tenth — the resting size beside each holding is published so a reader can judge whether their own size fits. It is not deducted from any return above.
A published measurement of what these markets did together. Not an account, not directly investable; W.E.T. never handles orders.

Indicative tape · 7 sessions
133 hourly readings since 2026-09-22 · not the governed closeINDICATIVEHourly readings that reprice the roster and frozen weights of the last governed close — only prices moved. Each one was computed and recorded at the timestamp it carries; nothing here is reconstructed from venue history. They carry no sentinel screen, enter no ledger and join no checksum chain, and a refused hour breaks the line rather than being drawn through. The daily WET Close is the official value.
Daily close
28d published · interactive28 published close(s) — 0–100 (Low support → High support). Drag to pan, scroll to zoom. One slot per published close, not one per day: dates on the axis are real, the spacing between them is not. 12 day(s) inside this window published no close and are not drawn at all. For the calendar-true spacing, read the chart below. Drawn as a line, not candles: a daily close carries no open, high or low, and a candle would assert an intraday range nobody observed.

WARTI · at a glance
- What it is
- 18 culture markets carrying the "artist" axis across polymarket, every one resolving inside six months, tracked as one composition.
- High vs low
- Higher = the markets are more torn — prices across the composition sit closer to a coin flip. Lower = more decided, in EITHER direction: a basket priced at 5% and one priced at 95% both read low. A reading of market prices, not a W.E.T. forecast.
- Who cares
- Anyone tracking how artist is being priced across venues on a composition of at least 6 markets resolving inside 200 days.
