Will Natural gas price on Oct 22, 2026 at 5:00 PM EDT close above $3.150?
6 seats worked this question alone; the panel agreed within a few points, so no debate was run. Code ran every test and computed the number. How the desk works
Judged by Kalshi KXNATGASD-26OCT2217-T3.150 settlement at 2026-10-22: If the close price of the 1-minute candlestick for natural gas on October 22, 2026 at 5:00 PM EDT is above 3.150 USD/MMBtu, then the market resolves to Yes.
The dispute that matteredAll six analysts agree directionally within 0.01-0.03, but F lands at 0.03 vs 0.01 for B/C. The substantive point is not direction but how much residual probability to reserve for an unmodeled discrete shock (supply disruption, data surprise) not visible in the backward-looking return distribution. Resolved by letting the pooled estimate (0.02) sit between the two clusters: F's reasoning (explicit rejection of causal drivers plus acknowledgment of model uncertainty) merits weight commensurate with its broader domain coverage rather than being averaged away, while the tail-event calculation itself is sound and not literally zero.
Synthesis
- Last settled close 2026-10-21 = $2.79/MMBtu
- Six-session price path declining from 3.198/3.236 down to 2.79, with acceleration in the final two sessions
- Daily log-return sample (n≈123-171): mean ≈0-0.1%, sd ≈2.64-2.74%, max observed single-day move = +8.68%
- 95th percentile single-day return in-sample ≈ +4.36%
- ADF test on price level: p=0.63 (fails to reject unit root/non-stationarity)
- HDD/CDD regression on returns: p=0.57 (insignificant), sign-unstable under leave-one-out and across regimes
- Calibration-weighted log-odds pooling across six analysts producing the committee point estimate of 0.02
- Empirical return distribution moments (mean, sd, skew, kurtosis, percentiles) fit to the historical daily-return sample
- Bootstrap 95% CI for mean daily return of [-0.45%, +0.37%], centered near zero with no detectable drift supporting a large one-day rally
- A move from $2.79 to above $3.150 requires a log-return of ~+12.1-12.9%, roughly 4.4-4.8 empirical standard deviations given sd of ~2.66-2.74%
- Momentum is negative and accelerating, arguing against a near-term mean-reverting bounce
- The required move exceeds the single largest daily move in the 123-171 day sample (+8.68%), placing it outside empirical support
- The -0.91 correlation cited by one analyst (n=12, autocorrelation 0.95) is most likely spurious/confounded trend co-movement rather than a usable causal lever
- Probability that natural gas settles above $3.150 at 5:00 PM EDT on 2026-10-22 is approximately 0.02, 95% credible interval [0.01, 0.04]
- Expected one-day log-return of the underlying is approximately 0 (no detectable drift), consistent with settlement remaining near the $2.70-2.90 range absent a shock
- If a YES contract on this strike is priced efficiently near the committee probability, expected return of taking either side is approximately zero; mispricing materially above this level would represent a short-YES edge
- Whether a discrete supply/demand shock between 11:30 UTC and 5:00 PM EDT on 10/22 could produce an outsized move not captured by the backward-looking return distribution
- Whether the true tail shape of natural gas returns is fatter than the observed 123-171 day sample suggests, since the sample may lack a prior analog of a genuine supply-shock day
- Whether the six analysts' near-identical sd/momentum calculations constitute independent confirmation or are largely one duplicated line of evidence from a shared price series
- The actual current market-implied price for this contract is not observed in the evidence provided, so any trade recommendation is conditional on a separately-checked market price
| Commodities Analyst (A) | 0.16 | High domain relevance but weakest calibration (Brier 0.286); evidence duplicates the shared price-series/sd calc used by most others, limiting marginal independent information. |
| Weather Analyst (B) | 0.14 | Decent calibration (Brier 0.287, acc 0.53) and adds one distinct test (ADF non-stationarity), but weather relevance is secondary here since no weather evidence was actually cited; discounted for redundant return-distribution evidence. |
| Public Markets Analyst (C) | 0.21 | Best calibration in panel (Brier 0.257, acc 0.536), highest router weight, directly relevant domain for a settlement question. Weighted up for calibration quality despite overlapping evidence. |
| Quantitative Researcher (D) | 0.17 | Adds genuinely independent evidence: bootstrap CI on mean daily return and empirical max-move check (required move exceeds max observed historical move). Mid-pack calibration. |
| Positioning Analyst (E) | 0.12 | Lowest confidence and weakest accuracy in panel; evidence nearly identical restatement of others' sd-multiple argument with no new data source. |
| Causal Skeptic (F) | 0.20 | Only analyst to explicitly test and reject a causal weather-demand driver and flag a likely spurious correlation; broadest domain relevance. Slightly higher P1 (0.03) reflects appropriate reserve for unmodeled shocks. |
- If the officially settled natural gas price at 5:00 PM EDT on 2026-10-22 is above $3.150, this consensus is falsified.
- If a verifiable discrete news event (pipeline outage, EIA storage surprise, extreme cold alert) occurs before 5:00 PM EDT 10/22 and the committee did not update probability in response, the forecast process should be flagged as having ignored material new information.
- If the realized intraday move for 10/22 exceeds 3 standard deviations relative to the stated sd (~2.7%) in either direction, the volatility assumption underlying this estimate should be re-examined for future horizons.
- ADF non-stationarity test on the price level (Analyst B, s3)
- Bootstrap 95% CI on mean daily return and explicit max-historical-move comparison (Analyst D, s2/s4)
- HDD/CDD regression tested and rejected as a causal driver, with instability diagnostics (Analyst F, s3-s5), plus flagging of a likely spurious high correlation (s6)
Applicable to a short-horizon (1-day), range-bound-to-trending natural gas pricing regime with no major scheduled catalysts (e.g., EIA storage report, extreme weather event) identified in the evidence window; would not apply if a discrete catalyst between now and settlement is confirmed, in which case the volatility and distributional assumptions underlying this estimate would need to be discarded in favor of event-specific analysis.
The core sd-multiple/tail-probability argument assumes the historical 123-171 day return distribution is a reasonable proxy for tomorrow's conditional distribution; it does not explicitly model regime shifts, discrete jump risk from news/weather shocks, or the possibility that the empirical sample underrepresents rare supply-side events. No analyst had access to the actual market-implied (Kalshi) price, so the trade recommendation is conditional rather than directly actionable from this evidence alone.
The seats
Commodities Analyst2%
0% Unconditional probability that a single daily return draws a +12.9% move given observed return distribution (mean~0.1%, sd~2.67%, n=123)
Natural gas is notoriously volatility-prone around shoulder-season weather surprises and storage report revisions; a single bullish EIA storage miss or an unexpected early cold snap forecast (d3/d4/d5 weather proxies show declining but still nonzero HDD-type readings) could trigger an outsized single-day squeeze, especially if the market is already oversold after six straight down days (RSI-style mean reversion). The 4.8-sigma estimate assumes a stable Gaussian-like regime, but nat gas return distributions are fat-tailed and regime-dependent; the actual historical frequency of >10% one-day moves in Henry Hub is higher than Gaussian models imply, especially during October-November withdrawal-season repricing.
- Price has fallen steadily from 3.198 (10/14) to 2.79 (10/21), a -12.8% six-session decline, with the most recent close already 2.79 — 0.36 below the 3.150 threshold.
- Daily return series shows persistent negative prints in the last 4 of 6 sessions (-0.0186,-0.0311,-0.0584 most recent), indicating accelerating downside momentum, not reversal.
- Return sd ≈2.67%, mean≈0.1%/period; a move from 2.79 to >3.150 requires +12.9%, roughly 4.8 standard deviations above the mean — essentially a tail event under the empirical distribution even accounting for the modest positive skew (0.29) and kurtosis (0.56).
If the Kalshi KXNATGASD-26OCT2217-T3.150 1-minute candle close at 2026-10-22 5:00 PM EDT is reported at or above 3.150 USD/MMBtu, this forecast is falsified; conversely if it closes materially below (e.g., <2.95), it is strongly confirmed.
- d1's last value (2026-10-21=2.79) is the most recent observed settlement/closing price prior to the as_of timestamp (2026-10-22 11:30 UTC, i.e., pre-market for the Oct 22 session).
- d2 return series sd (~2.67%) is a reasonable proxy for one-session volatility in the underlying index used for Kalshi settlement.
- No major scheduled data release (e.g., EIA storage report) between as_of and 5pm EDT settlement is assumed already partially priced into recent decline; no information on any pending catalyst is available.
- Kalshi settlement index tracks the front-month NYMEX/Henry Hub proxy closely enough that the d1 series is representative.

Given the last observed close of 2.79 (10/21), a settlement above 3.150 by 5pm EDT on 10/22 requires a same-day move of roughly +12.9%, which is far outside the empirical daily volatility of this series. Combined with persistent negative return momentum and softening weather-demand proxies, the base case is a close well below 3.150.
The gas price closed Oct 21 at 2.79 USD/MMBtu, roughly 12.9% below the 3.150 strike. Given realized daily volatility near 2.66% (log-return sd), a move of that magnitude in a single trading session is a ~4.5-sigma event, making YES resolution essentially negligible even after accounting for fat tails in the return distribution.
Natural gas closed at 2.79 on 2026-10-21, roughly 13% below the 3.150 strike. Given observed daily return volatility (sd≈2.74%) and a six-session downtrend with accelerating negative daily returns, clearing 3.150 by Oct 22 5PM EDT requires an approximately 4.4-sigma one-day rally against prevailing momentum — a near-impossible move absent a discrete supply/demand shock not visible in this data.
Natural gas closed Oct 21 at $2.79 (d1), down from $2.963 and $3.058 the two prior sessions — a clear 3-day downtrend of roughly -2.3% to -5.8%/day. To settle above $3.150 by 5PM EDT Oct 22, price must rise +12.9% intraday. Daily return distribution (d2/d3, n=123-171) has mean ≈0%, sd ≈2.66-2.74%, and even the empirical max observed return is +8.68% (s2/s3 max). A +12.9% move is ~4.7-4.8 standard deviations from the mean and exceeds the largest single-day move seen in the 123-171 day sample, placing it outside the empirical support of the distribution.
The $3.150 strike is now deep out-of-the-money given the latest observed price of 2.79 (10/21), a required one-day log-return of +12.1% versus a measured daily sd of only 2.64%. Price action shows a persistent down-trend (3.236→3.116→3.058→2.963→2.79 over the last five sessions) with no reversal signal, so both the statistical base rate and the directional momentum argue for a very low YES probability. The market (Kalshi strike price, not observed directly here) should already be pricing this near zero; there is no edge in buying YES at any price above a few cents, and the trade, if anything, is a sell-YES/buy-NO carry play given continued downward drift risk.
The observed price series (d1) shows natural gas in a persistent 7-day downtrend ending at $2.79 on 10/21, roughly $0.36 (≈12.9% log-return) below the $3.150 strike. Given daily log-return volatility of ~2.66% (d2, s1), a move of that magnitude within one trading day is a ~4.5-5 standard deviation event under the empirical distribution — far outside anything seen in the 123-day sample (max observed daily log return = +8.68%, s2). No causal mechanism in the provided evidence supports such a jump: the HDD/CDD regression (s3) is statistically insignificant (p=0.57), unstable under leave-one-out (s4, sign flips), and regime-dependent (s5, sign changes across regimes) — it should not be treated as a reliable driver of a one-day reversal. The strong correlation in s6 (-0.91) is likely spurious: n=12, extreme autocorrelation (0.95), and almost certainly reflects a shared trend/seasonal confound (e.g., both price and the counterpart series drifting together over the sample window) rather than a causal lever that could produce a 13% intraday reversal.

Base rate: for a commodity price series with daily log-return sd of ~2.66-2.74%, a same-day move of the magnitude required here (+12.1-12.9%, ~4.4-4.8 sigma) is, under a normal approximation, an extremely low-probability tail event (well under 1%); even allowing for fat tails (observed kurtosis is only mildly elevated at 0.56), the empirical data show the largest move in the 123-171 day sample was +8.68% — the required move exceeds anything observed in-sample. Starting from that near-zero statistical base rate, the committee's analysts (P0 range 0.01-0.03) made only a small upward adjustment to account for (a) generic fat-tail/jump risk in energy markets, and (b) the small-but-nonzero chance of a discrete supply shock before settlement. Crowding/independence caveat: four of six analysts (A, C, D, E) and partially B essentially re-derive the same calculation — last close 2.79, required log-return ~12-13%, divided by sd ~2.66-2.74% → ~4.5 sigma — from what is almost certainly the same underlying price series. This is effectively one line of evidence, not four independent confirmations. I weighted Analyst C (best calibration, Brier 0.257) and Analyst F (Causal Skeptic, broadest relevance and the only one to explicitly test and reject a causal weather-demand driver) most heavily, and discounted E (weakest calibration, no new evidence). Analyst D's bootstrap CI and max-historical-move check, and B's ADF non-stationarity test, were treated as the only genuinely incremental evidence beyond the shared sd calculation. Top disagreement, resolved above: F's P1=0.03 vs the 0.01 cluster reflects tail-risk reserve for unmodeled shocks rather than a data disagreement; pooled estimate of 0.02 sits between the clusters. Tradeability: This is a well-specified, nearly mechanical volatility-threshold question with high data quality and low novelty — any analyst with the price history and a calculator reaches a similar conclusion — which is exactly the setup likely to already be efficiently priced by the market. The evidence provided does not include the actual current market/Kalshi price for the contract, so I cannot state a confident edge. If the observed YES price is already near a few cents, there is no actionable edge over the 0.02 consensus and the trade should be passed. If the observed YES price is meaningfully above ~5-8 cents (e.g., due to illiquidity or stale pricing), the expression would be: sell/short YES (or buy NO) on the >$3.150 strike, sized small given the binary tail-risk payoff structure and the inability to adjust intraday before the hard 5:00 PM EDT settlement.
Assumptions
- holdingd1's last value (2026-10-21=2.79) is the most recent observed settlement/closing price prior to the as_of timestamp (2026-10-22 11:30 UTC, i.e., pre-market for the Oct 22 session).
- holdingd2 return series sd (~2.67%) is a reasonable proxy for one-session volatility in the underlying index used for Kalshi settlement.
- holdingNo major scheduled data release (e.g., EIA storage report) between as_of and 5pm EDT settlement is assumed already partially priced into recent decline; no information on any pending catalyst is available.
- holdingKalshi settlement index tracks the front-month NYMEX/Henry Hub proxy closely enough that the d1 series is representative.
- holdingThe last observed price in d1 (2.79 on 2026-10-21) is representative of the pre-market/overnight starting level for the Oct 22 settlement window.
- holdingThe empirical daily return distribution (s1) from the trailing ~123-session sample is a reasonable proxy for the volatility regime still in effect on Oct 22.
- holdingNo single, unannounced macro/weather shock between 11:30 UTC and 21:00 UTC (5pm EDT) on Oct 22 is assumed beyond what's embedded in the recent trend/degree-day data (d3, d4).
- holdingDegree-day anomaly series (d3, d4) are too noisy/short-horizon to materially shift the 1-day probability estimate beyond the price-return-based calculation.
- holdingd1 and d2 last-date alignment (2026-10-21) confirms these are daily series, with no higher-frequency intraday data available to detect any pre-market move on 10/22 before the 11:30 UTC as_of snapshot.
- holdingNo major scheduled EIA storage report or extreme cold forecast is assumed between as_of and settlement based on available data (none provided).
- holdingd3 and d4 (likely related futures curve or dollar/rate proxies) show mild declining trend but are not directly incorporated as they lack clear causal linkage in the given data to spot gas price without further context.
- holdingd1's last value ($2.79, Oct 21) is the most recent price anchor before the Oct 22 settlement window
- holdingd2/d3 return series are daily returns on the same or closely related underlying as the settlement price
- holdingNo major scheduled catalyst (e.g., EIA storage report) occurring Oct 22 is known to the analyst beyond what's in the data
- holdingKalshi settlement uses the 1-minute candle close at 5PM EDT, which should track the broader daily price level closely
- holdingd1's last value (2.79 on 10/21) is a reasonable proxy for the current underlying price ahead of the 10/22 5pm EDT settlement window.
- holdingDaily return distribution (d2/s1) is a fair approximation for the remaining intraday move, despite s3 flagging non-stationarity in price levels (differenced series/returns are the correct basis for this estimate).
- holdingNo major scheduled fundamental catalyst (e.g., EIA storage report surprise) occurs between 11:30 UTC and 21:00 UTC on 10/22 that is already reflected in d1/d2 — this is unverifiable from the given data and is the key residual risk.
- holdingd4 (open interest/volume proxy, ~180k-250k range) reflects underlying futures market activity, not Kalshi contract-specific positioning, so it is only a weak crowding proxy for this specific binary market.
- holdingd1's last value (2.79 on 10/21) is reasonably close to the actual price level at the start of the as_of window (10/22 11:30 UTC), i.e., no large unobserved overnight gap has already occurred.
- holdingThe Kalshi settlement series tracks the same underlying front-month futures contract represented in d1/d2/d6.
- holdingDaily log returns are approximately the right scale for assessing the plausibility of a 1-day move, even though the resolution is based on a single 1-minute candle at a specific time (which could in principle be a brief spike, but settlement-at-close framing argues against relying on a transient wick).
