Why Hypersight exists
Poll-only models fail in predictable ways: thin samples, house effects, late breaks,
and races where the average never moves even as money and ads do. Single-signal
stories (cash rankings, generic ballots, one flashy poll) overfit the last narrative.
Hypersight was built to be a rigorous multi-signal engine — accuracy- and
recency-weighted polls where they exist, FEC-backed finance and ad pressure where
they matter, and partisan structure as a baseline — trained and tested walk-forward
so we never peek at the cycle we score.
How a race is scored
-
Identify the contest. House
ST-##
or Senate state for the cycle (e.g. 2026).
-
Load signals. Live/weighted polls, FEC receipts, independent
expenditures, lean/incumbent, engagement proxies, and optional markets.
-
Blend & calibrate. A full-signal model turns features into
P(Dem win). Close races up-weight money and ads.
-
Publish. Map color, rating band, projection seats, and the
weights modal you open by clicking a district or state.
On the map: hover for a snapshot; click for the full signal
breakdown (weights, direction, model drivers). That modal is the same stack described
below.
Signals & approximate weights
When all core inputs load, the blend is roughly:
-
40%
Polls
Accuracy × recency × sample-size weighted average — not a flat mean of pollsters.
-
18%
Money raised
FEC candidate receipts for the cycle (Dem share of major-party haul).
-
15%
Ad spend
Independent expenditures + campaign disbursement proxy for air/digital pressure.
-
10%
Lean & incumbent
District/state partisan baseline and whether the seat is open or held.
-
8%
Digital / grassroots
Engagement proxy from campaign and outside spending patterns.
-
5%
Enthusiasm & favorability
National mood and net favorability when available.
-
4%
Demographics & party committees
Structural shifts plus DNC/RNC-style committee capacity share.
Close races adapt. When the race is tight (roughly |margin| under 6 points),
Hypersight up-weights money and ads so late fundraising and IE waves can move the call.
Markets (e.g. Polymarket) and third-party presence layer on when data exists.
What Solid, Lean, and Toss-up mean
Ratings come from Democratic win probability. They are confidence bands, not guarantees.
Map colors use the same scale as these bands: blue for Dem favorites,
brand green for toss-ups, red for GOP favorites.
Solid D / R≥ ~95% for the favorite
Likely~85–95%
Lean~65–85%
Tilt~55–65%
Toss-up~45–55%
A Solid rating usually means polls, money, ads, and partisan lean all
point the same way with a large edge. High confidence under current data — not a promise
that nothing can change.
Past performance (walk-forward)
We train only on prior cycles and score the next one — the same constraint a real
forecaster faces. Headline House/Senate results:
~93%
All seats with full finance signals
94–96%
Polled races with a clear margin (≥5–8 pts)
~84%
All races with usable polls
~69%
Competitive / toss-up band — still hard
On a 2024 holdout (model fit only through 2022), Hypersight correctly called about
95% of House and Senate seats in our
feature set. Close actual races (two-party vote near 50%) remain the stress test —
accuracy falls into the mid‑70s there, which is where multi-signal blends earn their keep.
Where multi-signal beat a simple average of polls
Many public forecasts still start from a flat average of surveys. That “poll average”
is useful — and it is only one channel. Hypersight accuracy- and recency-weights every
poll, then blends finance, ads, and structure so a noisy mid-pack average does not get
the final word.
Below are walk-forward holdouts (model trained only on prior cycles). In each
case a simple two-party poll-average forecast pointed at the wrong winner; Hypersight’s
multi-signal probability pointed at the eventual winner. Retrospectives on public
features — not election-night posts.
2018 · Indiana Senate
Poll average slight Dem · Hypersight strong R · GOP flipped the seat
Aggregated two-party poll share sat essentially at a toss-up / thin Dem edge
(~50%). Hypersight’s blend put Democrats near ~31% to win. Mike Braun defeated the
Democratic incumbent — the multi-signal call, not the poll average, had the winner.
2018 · TX-07
Poll average slight R · Hypersight strong D · Dem flipped the seat
Simple poll averages hovered just under 50% Dem (a soft Republican lean). The full
stack pushed a clear Democratic probability. Democrats took the district — again
matching Hypersight over the poll-mean favorite.
2020 · AZ-06
Poll average slight Dem · Hypersight R · GOP held
Survey averages put Democrats a hair over 50%. Hypersight stayed Republican on the
blend of polls, money, ads, and lean. The seat stayed with the GOP — wrong favorite
if you stopped at the poll average.
2022 · WI-03
Poll average Dem · Hypersight R · Van Orden won
Two-party poll/forecast share averaged Democratic. Multi-signal probability favored
Republicans. The Republican carried the district — a clean miss for a poll-mean
call and a correct multi-signal one.
2024 · CA-13
Poll average ~ coin flip · Hypersight Dem · Dem won
Available two-party forecast shares sat near 50%. Hypersight’s full blend pushed a
clear Democratic probability and matched the razor-thin certified result.
Bonus · 2018 NV Senate · 2022 NV Senate
Poll average soft R lean · Hypersight Dem · Dem held
In both cycles Nevada’s poll averages sat a tick under 50% Dem. Hypersight stayed
firmly Democratic and the Democratic nominees won — another pattern where the mean
of surveys understated the eventual winner.
Why this matters. An average of polls is a forecast of what pollsters
measured — not always of what voters will do. Hypersight keeps surveys (weighted
properly) and refuses to stop there.
Limits & honesty
No model calls every toss-up. Special elections, scandal, nominee quality, and late
ad blitzes can move races after a snapshot freezes. Jungle primaries and multi-candidate
fields need care. Photos and names come from FEC and public legislator data and can lag
filings.
