final rationale
Mean of 5 draws (0.74, 0.74, 0.75, 0.72, 0.65). (0) Not yet resolved: the market resolves on full calendar-2026 performance, so the remaining ~70 trading days through Dec 31 still matter; the resolution-source fetch failed, but FRED shows the S&P 500 at 7,764.7 on 2026-09-21 (+13.4% price vs the 6,845.5 year-end 2025 close, ~+14.5% total return) while gold sits ~$4,307 vs a ~$4,318–4,333 year-end 2025 baseline, i.e. roughly flat-to-slightly negative YTD; multiple independent trackers (chartrow, Motley Fool, equiti) corroborate a 10–14pp equity lead. (a) ~3.3 months / ~70 trading days remain. (b) Status quo: S&P TR is ahead by ~10–14pp, so if nothing changes the market resolves Yes. (c) NO scenario: the freshly started Fed hiking cycle, stretched valuations and narrow breadth trigger a 10–15% equity selloff while gold, supported by record ETF/central-bank buying, rallies back toward Goldman's $4,900 target — a ~15–20pp relative swing is plausible given gold's own 25% intra-year range. (d) YES scenario: trend continuation, with hawkish Fed rhetoric pressuring non-yielding gold and equities holding near record highs. A zero-drift normal model with gap-volatility ~2%/day gives σ≈16% over the remaining window; z≈0.65–0.9 implies ~75–82% for Yes, and the ~56% calendar-year base rate for stocks is a mild tailwind. The Kalshi anchor is 63%, but it fell 15 points over 30 days in a thin market (56 contracts/day) while the fundamental gap actually widened (gold −7.4% in the month), so I treat the drop as noise/positioning and shade toward the model but keep meaningful weight on fat-tail reversals and possible baseline/source differences, landing at 0.74.

Planner reasoning
This is a year-to-date relative performance question: S&P 500 Total Return vs gold for calendar 2026, with ~3 months left. The key structured data are current YTD levels of both assets (FRED has SP500 and gold price series; earnings_data can give SPY/GLD proxies), the Kalshi price anchor, and related markets on S&P year-end levels and gold prices for cross-checking. Code execution can compute the current YTD gap from returned numbers and, given historical volatility, the odds of the gap flipping over the remaining period.

Research loops, bottom lines
- current state: As of Sept 22, 2026, the S&P 500 (price ~7,765, record-high territory with 25+ ATHs in 2026) is up roughly 13-15% total return for calendar 2026, while gold (~$4,300-4,350) is essentially flat to slightly down for the year after retreating ~7% from its January 28 all-time high near $5,589 — meaning the S&P is currently comfortably ahead of gold for the 2026 period that the market resolves on, consistent with the Kalshi market's own probability having risen to ~65% favoring S&P outperformance by
- base rate: The long-run base rate modestly favors stocks over gold in any given calendar year (~56% S&P wins vs ~44% gold wins across 55 years, and post-election years skew even more toward stocks at roughly 14-of-24), and the current 2026 in-year trend (S&P +12–13% vs gold +3% YTD) already sits solidly in the "stocks win" camp with over three months left to the deadline — though 2025's extreme gold outperformance is a reminder that large reversals are historically possible within a single year.
- yes case: The most likely path to YES is simply the continuation of the current trend already in evidence: S&P 500 total return is up roughly +11–12.5% YTD through mid-September 2026, while gold is essentially flat-to-slightly-negative YTD (having given back its entire January-to-February spike from ~$5,600 to ~$4,300), and rising Fed-hike expectations are an active headwind for non-yielding gold into Q4 — a combination that would need to reverse dramatically (e.g., a sharp equity selloff or a renewed gol
- no case: The S&P 500 currently holds a large (~10 percentage-point) YTD lead over gold, but a freshly begun Fed hiking cycle, historically-linked bear-market precedent, stretched equity valuations, narrow market breadth, and resurgent gold ETF/central-bank demand all provide plausible pathways for gold to claw back the gap before the January 1, 2027 close, meaning NO is not a fringe outcome despite the current trend favoring YES.

report: current state
- [2025-12-31] S&P 500 closed calendar-year 2025 at 6,845.50, up 16.39% for the year; this is the baseline start-of-2026 level relevant to the "for the period of 2026" resolution wording.
Stocks posted a four-session losing streak, although the declines were mild and the S&P 500 still locked in a 16.39% gain for the year, its third straight double-digit annual advance.
- [2026-01-28] Gold hit its 2026 all-time intraday/spot high.
Gold's all-time high is $5,589.38 per ounce, reached on January 28, 2026.
- [2026-05-19 to 2026-05-27] The Kalshi market itself ("Will the S&P 500 outperform gold this year?", strike/expiration Jan 1, 2027) saw its implied "Yes" (S&P wins) probability jump sharply from 35% to a peak near 65% in late May, even though gold had outperformed on a trailing-12-month basis at the time.
The probability of the S&P 500 outperforming gold rising from an initial 35.0% to a recent high of 65.0%. The trend is defined by two sharp price increases in late May. A significant 19.0 percentage point spike occurred around May 19, followed by a 9.0 percentage point jump around May 22.
- [2026-05-27] As of that date, gold's medium-term trailing performance was still ahead of stocks (a legacy of 2025's rally), but the market/model already gave the S&P the edge for the 2026 calendar year specifically.
Both the model and the market expect the S&P 500 Total Return Index to achieve a higher annual return than Gold, with no compelling evidence of mispricing.
Model put S&P at 71.3% vs Gold 28.7%, market at 65%/36%.
- [2026-08-04] S&P 500 returned to a record closing high of 7,737, ending a two-month, ~5% pullback, as Dow topped 54,000 for the first time.
The S&P 500 closed at a record high Tuesday, supported by strong corporate earnings, a rebound in tech shares and traders embracing hopes for progress on reopening the Strait of Hormuz. The S&P 500 surged 1.79% to close at 7,737 points, its first record high in two months.
- [2026-08-06] By early August the S&P had already logged 25 record closes in 2026.
The S&P 500 has closed at an all-time high 25 times this year as of Tuesday's close, according to data I pulled from the Bloomberg Terminal.
- [2026-09-21] S&P 500 closed at 7,764.70, up 1.49% on the day.
The S&P 500 climbed 1.49% to end at 7,764.70, while the Nasdaq Composite gained 2.26% for a record close of 27,122.09 — its first since June.
This puts the index roughly 13.4% above its Dec 31, 2025 close of 6,845.50 in price terms alone (total return higher still with ~1.3-1.5% dividend yield).
- [2026-09-22] Gold fell to $4,307.63/oz, down 0.81% on the day, down 7.40% over the trailing month, and roughly flat to slightly negative versus its Dec 31, 2025 close of $4,318.18.
Gold fell to 4,307.63 USD/t.oz on September 22, 2026, down 0.81% from the previous day. Over the past month, Gold's price has fallen 7.40%, but it is still 14.44% higher than a year ago.
- [2026-09-10] Bank forecasts for gold's year-end level (Goldman $4,900, JPMorgan $4,500 for Q4, BofA $4,360, HSBC $4,560 average) all sit at or modestly above the current spot price, but well below the earlier-2026 peak near $5,589.
Goldman Sachs holds a year-end target of $4,900. JPMorgan projects a Q3 average near $4,300 and a Q4 target of $4,500. Goldman Sachs ($4,900), JPMorgan ($4,500 for Q4), Bank of America ($4,360), and HSBC ($4,560 average) all still sit at or above gold's current price.
- [2026-09-10] Gold ETF demand remains strong (World Gold Council data), a bullish structural factor for gold even as price has stalled recently.
The World Gold Council reported on September 9 that global gold-backed ETFs took in $18 billion in August, the second-largest monthly inflow on record. Holdings rose 121 tonnes to an all-time high of 4,189 tonnes, and total ETF assets climbed 16% to $615 billion.
- [2026-09-18] U.S. equities remain near highs but choppy; S&P was around 7,651 mid-September before rallying further by Sept 21, while Treasury yields and Middle East oil-supply concerns are near-term swing factors for both assets.
The main stock market index of United States, the US500, rose to 7651 points on September 18, 2026, gaining 0.17% from the previous session. US stock indices closed mixed on Friday as Treasury yields rebounded, rekindling concerns about a deteriorating macroeconomic backdrop.
BOTTOM LINE: As of Sept 22, 2026, the S&P 500 (price ~7,765, record-high territory with 25+ ATHs in 2026) is up roughly 13-15% total return for calendar 2026, while gold (~$4,300-4,350) is essentially flat to slightly down for the year after retreating ~7% from its January 28 all-time high near $5,589 — meaning the S&P is currently comfortably ahead of gold for the 2026 period that the market resolves on, consistent with the Kalshi market's own probability having risen to ~65% favoring S&P outperformance by late May 2026.

- [2026-05-27] A quantitative market-analysis (Octagon, tracking the actual Kalshi market) notes the S&P 500 outperformance probability has already risen sharply:
the price chart for this market indicates a strong upward trend, with the probability of the S&P 500 outperforming gold rising from an initial 35.0% to a recent high of 65.0%. The trend is defined by two sharp price increases in late May.
https://www.octagonai.co/markets/financials/match-ups/annual-return-s-p-500-total-return-vs-gold
- [2026-05-27] The same model-based analysis put the S&P 500 as favorite over gold:
Both the model and the market expect the S&P 500 Total Return Index to achieve a higher annual return than Gold, with no compelling evidence of mispricing.
Its outcome table gave the model 71.3% to S&P 500 vs 28.7% to gold at that time. https://www.octagonai.co/markets/financials/match-ups/annual-return-s-p-500-total-return-vs-gold
- [2026-05-27] Bullish equity catalysts cited include a raised sell-side target: the report notes "Goldman Sachs projects strong S&P 500 returns by 2026, driven by anticipated AI-led earnings growth," with Goldman having raised its S&P 500 year-end target to 8,000. https://www.octagonai.co/markets/financials/match-ups/annual-return-s-p-500-total-return-vs-gold
- [2026-09-10] Gold's near-term momentum has stalled amid hawkish Fed rhetoric raising rate-hike odds, which is a headwind for a non-yielding asset:
Gold holds near $4,380 as hot August PPI lifts September hike odds toward 60%... the mixed print pushed September hike odds to roughly 60% by the morning of September 10.
https://goldsilver.com/industry-news/article/gold-price-outlook-september-2026/
- [2026-09-22] Fed officials' hawkish tone is actively pressuring gold lower even as of the report date:
Gold fell toward $4,300 an ounce on Tuesday, extending losses from the previous session as hawkish comments from Federal Reserve officials strengthened expectations for further US interest rate hikes. On Monday, Chicago Fed President Austan Goolsbee said the central bank must account for persistent supply shocks, while St. Louis Fed President Alberto Musalem said additional increases may be needed to bring inflation toward the Fed's target.
https://tradingeconomics.com/commodity/gold
BOTTOM LINE: The most likely path to YES is simply the continuation of the current trend already in evidence: S&P 500 total return is up roughly +11–12.5% YTD through mid-September 2026, while gold is essentially flat-to-slightly-negative YTD (having given back its entire January-to-February spike from ~$5,600 to ~$4,300), and rising Fed-hike expectations are an active headwind for non-yielding gold into Q4 — a combination that would need to reverse dramatically (e.g., a sharp equity selloff or a renewed gold breakout above $5,000+) for gold to catch up by January 1, 2027.
NOT FOUND: An authoritative, single official S&P 500 Total Return Index level vs. an official LBMA/COMEX gold benchmark calculated identically over the exact May 19, 2026–Jan 1, 2027 market window (the question's specific measurement period); precise Kalshi market pricing/probability as of September 22, 2026 (only late-May 2026 data was available in the sources found).

BOTTOM LINE: The S&P 500 currently holds a large (~10 percentage-point) YTD lead over gold, but a freshly begun Fed hiking cycle, historically-linked bear-market precedent, stretched equity valuations, narrow market breadth, and resurgent gold ETF/central-bank demand all provide plausible pathways for gold to claw back the gap before the January 1, 2027 close, meaning NO is not a fringe outcome despite the current trend favoring YES.
NOT FOUND: The exact official Kalshi resolution source/base date convention (e.g., whether the "period of 2026" is measured from Jan 1, 2026 or from the May 19, 2026 market-open date) was not locatable in a fetched primary Kalshi rules page; also could not confirm the live current Kalshi contract price/probability as of September 22, 2026.

(0) Not yet resolved: the market resolves on full calendar-2026 performance, so the remaining ~70 trading days through Dec 31 still matter; the resolution-source fetch failed, but FRED shows the S&P 500 at 7,764.7 on 2026-09-21 (+13.4% price vs the 6,845.5 year-end 2025 close, ~+14.5% total return) while gold sits ~$4,307 vs a ~$4,318–4,333 year-end 2025 baseline, i.e. roughly flat-to-slightly negative YTD; multiple independent trackers (chartrow, Motley Fool, equiti) corroborate a 10–14pp equity lead. (a) ~3.3 months / ~70 trading days remain. (b) Status quo: S&P TR is ahead by ~10–14pp, so if nothing changes the market resolves Yes. (c) NO scenario: the freshly started Fed hiking cycle, stretched valuations and narrow breadth trigger a 10–15% equity selloff while gold, supported by record ETF/central-bank buying, rallies back toward Goldman's $4,900 target — a ~15–20pp relative swing is plausible given gold's own 25% intra-year range. (d) YES scenario: trend continuation, with hawkish Fed rhetoric pressuring non-yielding gold and equities holding near record highs. A zero-drift normal model with gap-volatility ~2%/day gives σ≈16% over the remaining window; z≈0.65–0.9 implies ~75–82% for Yes, and the ~56% calendar-year base rate for stocks is a mild tailwind. The Kalshi anchor is 63%, but it fell 15 points over 30 days in a thin market (56 contracts/day) while the fundamental gap actually widened (gold −7.4% in the month), so I treat the drop as noise/positioning and shade toward the model but keep meaningful weight on fat-tail reversals and possible baseline/source differences, landing at 0.74.

(0) Not resolved: the comparison runs through Dec 31, 2026; the resolution-source read failed (S&P DJI 403, LBMA page uninformative), so current state comes from FRED and news trackers. (a) ~100 calendar days / ~70 trading days remain. (b) Status quo strongly favors YES: FRED shows S&P 500 at 7,764.7 on 2026-09-21 vs 6,845.5 at end-2025 (+13.4% price, ~+14.5% total return), while gold is ~$4,307 vs ~$4,318-4,333 year-end 2025 (flat to slightly negative), a lead of roughly 14-15 percentage points; multiple sources (chartrow, Motley Fool, Equiti, TradingEconomics) corroborate S&P +11-13% vs gold ~0-3% YTD. (c) NO requires a sharp Q4 equity drawdown (the Fed just began a hiking cycle, valuations are stretched, oil/Iran risk) coinciding with a gold rally back toward $4,900-5,000; given gold's realized daily vol (~1.5-1.8%) and S&P's (~1%), the gap's ~70-day standard deviation is roughly 15-18pp, so a 14-15pp reversal is about a 1-sigma event (~15-22%). (d) YES simply needs the current trend to hold, helped by hawkish Fed rhetoric pressuring non-yielding gold. The Kalshi anchor is 63%, but it has fallen 15 points in 30 days on ~56 contracts/day even as gold dropped 7% and the S&P hit new highs, which looks like thin-market noise rather than information; a zero-drift model on the actual gap gives ~78-85%, and I shade toward the market for tail/resolution-convention risk (e.g., measurement window ambiguity), landing at 74% YES.

(0) Not resolved: the comparison is for calendar 2026 and will only be settled after Dec 31, 2026; the resolution-source fetch returned no usable comparison. (a) ~100 calendar days / ~70 trading days remain to the Jan 1, 2027 close. (b) Status quo strongly favors YES: FRED shows the S&P 500 at 7,764.70 on 9/21 vs a 6,845.50 2025 close (+13.4% price, ~+14.5% total return), while gold at ~$4,307 (TradingEconomics 9/22) is flat-to-slightly-negative vs its ~$4,318–4,333 year-end 2025 level, so the S&P TR leads by roughly 14–15pp; even if the venue measured from the May 19 open, the S&P appears ahead. (c) NO scenario: the newly begun Fed hiking cycle, stretched valuations, narrow breadth, and Iran/oil shocks trigger a 10–15% equity selloff while gold catches a safe-haven bid back toward Goldman's $4,900 target — a ~15pp swing that requires roughly a 1-sigma move in the return gap given elevated 2026 gold volatility. (d) YES scenario: trends simply persist — S&P near record highs and hawkish Fed rhetoric weighing on non-yielding gold. A zero-drift model with a ~15pp gap and ~15–18% remaining gap-volatility gives roughly 80–85% for YES; I shade toward the Kalshi anchor of 63% (thin, 56 contracts/day, and its 30-day decline is hard to reconcile with gold falling 7% over the same month) and fat-tail regime risk, landing at 0.75.

(0) The outcome is not already resolved: the fetched LBMA page provides no comparative 2026 performance data and the S&P source returned HTTP 403, so year-end benchmark values still must show the S&P 500 Total Return Index ahead of gold by at least 0.001%. (a) About 100 days remain until the January 1, 2027 close, representing roughly one quarter of trading in which the current gap can change materially. (b) If prices remain near September 22 levels, YES wins comfortably because the research places S&P total return around 12–15% YTD while gold is approximately flat to up only a few percent. (c) NO could result from a sharp equity correction amid high valuations, rate hikes, oil and geopolitical risks, combined with a safe-haven gold rebound toward forecasts such as Goldman's $4,900 target. (d) YES results if equities merely retain most of their current lead while hawkish monetary policy continues restraining non-yielding gold. I anchor on Kalshi's 63% YES price but raise it to 72% because several dated trackers indicate a roughly 10-plus-point current S&P lead; I stop well short of certainty because official benchmark prints and Kalshi's exact gold/base-date convention were not verified, the contract is thin, and gold demand remains strong.

(0) The condition is not already resolved: the fetched LBMA page provides no comparative performance data and the official S&P page was inaccessible, so final full-year returns must still be established through the 2026 year-end close. (a) About 100 calendar days, or roughly 70 trading days, remain until the January 1, 2027 close. (b) If current levels persist, Yes wins comfortably: reports place S&P 500 total return around 12-14% YTD, while gold near $4,308 is approximately flat versus its December 31, 2025 baseline. (c) No could result from a substantial Q4 equity correction alongside a safe-haven gold rally, with stretched stock valuations, a renewed Fed hiking cycle, record gold ETF holdings, and strong central-bank purchases providing a plausible mechanism. (d) Yes results if equities merely hold most of their current gain and gold remains near present levels; even forecasts around $4,500-$4,900 would require stocks to stagnate or decline materially for gold to overtake. I anchor on Kalshi's 63% Yes price and move modestly to 65% because several dated sources independently indicate a roughly double-digit current S&P lead, while retaining substantial No probability because exact official benchmark returns were unavailable and the thin market has recently fallen 15 points.
