Live results first. Backtest second.
Live figures are a trailing 30-day production log of first signals — recorded and scored automatically against final market resolution. Validation figures are out-of-sample across 15,000+ consecutive BTC 15-minute markets. Nothing is excluded from either set.
Live — 30-day rolling production average85.9%
Live production results, trailing 30 days. First signals — confidence above the model's threshold, with a positive edge — recorded live before resolution.
Backtest · first signal per market (8,085 markets)88.5%
Methodology. Each signal carries a model-confidence score, isotonically calibrated per time slot and assigned at issuance. A signal fires when that calibrated confidence clears a fixed threshold set ex-ante, with a minimum edge over the market price, applied uniformly — signals are designated before resolution, never selected afterward. "First signal" is the earliest fired signal in each market. The live signal policy additionally holds a market's final two minutes to a near-certainty bar: signals there resolve correctly ~98–99% of the time but are economically negligible at those prices, so the live policy declines them. Trimming those easy wins is why the live figure sits below the backtest — a deliberate trade of headline accuracy for economic honesty.
† Backtest figures are simulated, out-of-sample results and do not represent actual trading. Live figures are a complete production signal record, not trading results. Past performance is not indicative of future results. Trading event contracts involves substantial risk of loss. Individual results will vary materially.

Frequently asked.
01What is SpectralEdge?
SpectralEdge is a research-signal service for prediction markets. It reads BTC 15-minute markets in real time and signals YES or NO when confidence and edge are high, trained on patterns from 15,000+ historical markets.
02Does SpectralEdge place trades for me?
No. SpectralEdge is a signal service — a clear YES or NO signal when confidence and edge are high. You decide whether to act on a signal, and you place any trade yourself, in your own Kalshi account.
03How accurate are the signals?
Live, trailing 30-day production average: the first signal per market — confidence above the model's threshold, with a positive edge — resolved correctly 85.9% of the time. Out-of-sample backtesting across 15,000+ markets under the same signal policy. Signals fire on isotonically calibrated, per-time-slot confidence against a fixed ex-ante threshold — designated before resolution, never selected after. Backtest results are simulated and not a promise of future performance. Always apply your own judgment before trading.
04How fast are signals, and how often?
A fresh read every 5 seconds in real time, from market open through to resolution — so you're never waiting on the next read.
05Which markets does it cover?
BTC 15-minute prediction markets today. More liquid prediction markets are being added as the Cotes signal stack expands.
06Where do I actually place trades?
On Kalshi, in your own account. Each signal links straight to the relevant market, so you can place the trade there yourself.
07Do you ever hold my funds?
No. Your money always stays in your own Kalshi account, under Kalshi's custody. SpectralEdge doesn't connect to your Kalshi account, and Cotes never holds, accesses, or moves your funds.
08How much does it cost?
Start with a free trial — full access to every signal. After the trial, a paid subscription applies.
09Should I act on every signal?
Not necessarily. Treat each signal as a fast, data-backed read — check the market, your size, and the timing before you trade. The final decision is always yours.
