1 scheduled close did not land — the daily index publish was due at 10:37 UTC on 2026-09-15 and the newest print on file is still 2026-09-14. 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
Retired for vagueness · no longer on the board
This index was published under the desk’s current standard and withdrawn from the board by amendment v1.3 §10, which holds a universe to the bar the thesis has always been held to: a universe that declares only a category makes no claim any market could falsify. Its methodology, its inverse twin and its failure ladder were all compiled — the declaration of what it was about is what did not hold up. It is still published and its dated history is intact, but it is not part of the listed suite and should not be quoted as a current W.E.T. index. It returns to the board the day a committed spec declares a universe that names its subject — the bar it was refused by (`universe-names-no-subject`). Compiling a methodology is not the missing piece and never was. See the published suite →
W.E.T. Midterm Control Index
v1SlateMonthlyAs of Sep 14, 2026 · last moved Sep 13, 2026 · scale 0–100 (Map settled → Battleground)
How contested the 2026 midterm map is, across every race the market prices.
Retired — read instead: the published W.E.T. index suite. no like-for-like successor is published yet. This reading declared the `elections` category plus one venue tag and no vocabulary; its tag screen rejected 38 of 57 candidates on the measured board, which is real narrowing but reaches only one venue’s questions and leaves every other venue admitted whole. The chamber-control question is a good index and the desk intends to publish one — named to the chambers and seats it prices. This page and its full history remain published for continuity.

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.

Daily close
33d published · interactive33 published close(s) — 0–100 (Map settled → Battleground). 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.

The view this index measures
Every W.E.T. index tracks a question someone can hold a view on. This one is mapped to this question in the Worldview thesis map. Answering one places you on its continuum; this index is what that answer is measurable against.
How contested are the 2026 midterms?
Decided early, quiet cycleContested to the wire
Where do you stand? The Worldview builder asks from this same set of questions and matches your answers to the W.E.T. indexes that measure them.

- What it is
- The battleground gauge — how much of the 2026 map is still genuinely in play.
- High vs low
- Higher = more of the map is a genuine toss-up. Lower = the map is largely settled.
- Who cares
- Campaign desks and political reporters who need one number for how contested the midterm map is.
