Planner reasoning

This is a very long-horizon macro question (2032 annual US real GDP growth landing in a 0.5pp-wide bucket, 2.1–2.5%), so the market price is thin and the dominant evidence is the historical distribution of annual real GDP growth plus long-run consensus projections (CBO, Fed SEP longer-run, IMF). Key work: get the Kalshi price ladder across all buckets in KXGDPYEAR-32 to see the implied distribution, pull historical annual GDPC1 growth to build an empirical base rate for the 2.1–2.5% bin, and check the resolution definition (annual average vs Q4/Q4, and vintage/revisions).

# Event Kalshi market KXGDPYEAR-32-B2.3: resolves YES if US real GDP growth in calendar year 2032 falls between 2.1% and 2.5%. # Outcomes to forecast - Yes (2032 real GDP growth in [2.1%, 2.5%]) - No (growth outside that band) # Kalshi market anchor Current YES price: **20.00%** (up from 11% a month ago; 7-day and 30-day change both +9pp). Price range over last 10 days: 10–22%. Average daily volume ~1,249 contracts — active, liquid market with a clear recent upward drift toward this bucket. [kalshi_direct] # Sub-question answers 1. **Kalshi YES price / bucket distribution** — B2.3 (2.1–2.5%) = 20%. Full ladder not returned directly, but adjacent-year series show low-single-digit to mid-teens pricing for neighboring buckets (e.g., 2035 [1.6–2.0%] = 14%, 2036 [2.6–3.0%] = 5%), consistent with a wide, still-uncertain distribution this far out. [kalshi_direct, kalshi_related] 2. **Historical frequency 1950–2024/1990–2024** — Full sample (1948–2024, n=77): mean 3.13%, stdev 2.33%, only 8/77 (10.4%) years fell in [2.1,2.5]. 1990–2024 (n=35): mean 2.47%, stdev 1.74%, 5/35 (14.3%) in-band. 2000–2024 (n=25): mean 2.16%, 5/25 (20.0%) in-band — closest to current era. [code_execution] 3. **Official long-run projections** — CBO (Jan 2026): potential GDP growth 2.1%/yr 2026–2030, slowing to 1.8%/yr 2031–2036, implying **2032 ≈ 1.8%**, below the band's low end. Fed SEP (Mar 2026) longer-run median raised to **2.0%** (range 1.7–2.5%), also mostly below/at the low edge of the band. IMF specific 2032 US figure not found; medium-term convergence ~2% consistent with CBO/Fed. [claude_news] 4. **Resolution definition (annual avg vs Q4/Q4, BEA vintage)** — Not specified in rules text; no explicit Kalshi documentation found. Series match FRED's annual % change (A191RL1A225NBEA), the standard headline "real GDP growth" metric — most likely resolution source, but vintage (advance/final) ambiguity unresolved. [inference, no direct source] 5. **Earlier-year series cross-check** — No KXGDPYEAR-26 to -31 data was retrieved (kalshi_related search returned only 2035/2036 buckets, not adjacent-band pricing for closer years). Gap. 6. **Stdev / normal-model probability** — Historical annual stdev ≈1.7–2.3% depending on window. Normal-distribution model with mean 1.8–2.2%, stdev 1.5–2.2% gives P(2.1–2.5%) ≈ 7–11%, notably below empirical modern-era base rate (14–20%) because real-world growth clusters more tightly near trend than Gaussian tails suggest. [code_execution] # Key facts (high-confidence, factual) 1. [kalshi_direct] YES price 20%, up 9pp in both 7-day and 30-day windows — one of the largest short-term moves in this series. 2. [claude_news] CBO's official baseline projects 2032 real GDP growth near 1.8%, below the 2.1–2.5% band. 3. [claude_news] Fed's SEP longer-run median real GDP growth = 2.0% (Mar 2026), central tendency 1.8–2.0%, range 1.7–2.5%. 4. [code_execution] 2000–2024 empirical hit-rate for this exact band is 20%, matching current market price almost exactly. 5. [claude_news] Penn Wharton estimates AI could add up to 0.2pp to 2032 growth specifically, a potential upside catalyst nudging outcomes into/above the band. # Cross-market signals - Kalshi related: 2036 [2.6–3.0%] bucket priced at 5%; 2035 [1.6–2.0%] bucket at 14% — both suggest market assigns meaningfully more probability to sub-2.5% growth outcomes in the 2030s, consistent with CBO/Fed trend-slowdown narrative. - Polymarket: No matching GDP markets found. - Sportsbook implied: N/A (not applicable to economic data market). # Analyst opinions and speculation - CBO/Fed baselines point to trend growth converging near 1.8–2.0%, just below or at the low edge of this band — suggesting the "No" side (growth <2.1%) has strong institutional backing. - AI-productivity bulls (Penn Wharton) flag 2032 as a peak year for AI's productivity contribution (+0.2pp), a plausible mechanism pushing realized growth into the 2.1–2.5% band. - Empirical modern-era (2000–2024) base rates (14–20%) run well above parametric normal-model estimates (7–11%), reflecting tighter real-world clustering near trend. # Directional lean per outcome - **Yes (2.1–2.5%)**: Supported by 2000–2024 empirical base rate (20%, matches market price), Fed's upward-revised longer-run estimate (2.0%, near band's low edge), and AI-productivity upside scenarios. Recent sharp market repricing (+9pp) suggests some fresh bullish information/sentiment shift. - **No**: Supported by CBO's explicit 2031–2036 baseline (1.8%) sitting below the band, historical full-sample base rate only ~10%, and normal-distribution models (7–11%) implying market may be overpriced relative to structural forecasts. # Gaps / unknowns - No confirmation of exact Kalshi resolution data source/vintage (advance vs. final BEA estimate, annual-average vs Q4/Q4). - No pricing data retrieved for adjacent bins within the KXGDPYEAR-32 event itself (only the target bucket) — full distribution/de-vig unavailable. - No pricing for nearer-term comparable-year buckets (KXGDPYEAR-26 to -31) to validate typical market calibration for this bucket width. - Driver of the recent +9pp price surge is unexplained (no news tying it to a specific catalyst). - IMF's specific 2032 US GDP growth figure unavailable. # Calibration anchors - Kalshi current YES price: **20%** (anchor, trending up). - Historical precedent bands: full-sample base rate ~10%, 1990–2024 ~14%, 2000–2024 ~20% (best analog to current era, matches market). - CBO baseline (1.8%) and Fed longer-run median (2.0%) sit at/below band's low edge, arguing for some downside risk to current market pricing versus institutional consensus.

1. Both forecasters converge to nearly identical 18% estimates via the same reasoning path (market anchor + CBO/Fed shading down), producing a false sense of robustness—this is really one perspective duplicated, not two independent checks, and neither explores why the market might be right to be at 20% or higher (e.g., they don't seriously entertain that the market's +9pp move over 30 days could reflect actual incoming data/forecast revisions rather than noise). 2. Neither forecast addresses the "Gaps/unknowns" item about resolution vintage (advance vs. final BEA, annual-average vs Q4/Q4) — this is a real source of uncertainty that could shift which bucket the outcome lands in, and neither analyst flags it as a reason for wider uncertainty bands or hedging their point estimate. 3. Both forecasts ignore the cross-market signal that adjacent buckets (2035 [1.6-2.0%]=14%, 2036 [2.6-3.0%]=5%) imply the market's own multi-year term structure is trending toward lower growth over time — if 2032 sits between these two anchor years, its 20% price could actually be a local peak in the ladder reflecting the market's belief that mid-2030s growth is centered right around this band, which is a bullish case for the market being *correctly* calibrated (or even underpriced) rather than overpriced, a scenario neither forecaster raises. 4. Neither discusses the asymmetry in the "No" outcome — No comprises both a below-band (recession/slow growth) and an above-band (boom, e.g., strong AI upside beyond +0.2pp or fiscal stimulus) scenario, and both forecasts implicitly treat "No" as synonymous with "growth below 1.8-2.0%" without acknowledging the tail risk of a substantially stronger economy (e.g., 2.6%+) which further validates why "No" could be even higher than 82% if the true distribution has fat tails on both sides. 5. The 8-year lead time to 2032 (forecast made from 2026 CBO/Fed data) introduces significant projection-revision risk that isn't discussed — CBO and Fed long-run estimates are revised regularly, and neither forecaster flags that six more years of data/model updates could easily shift the "structural" 1.8-2.0% consensus by the time 2032 arrives, making current institutional baselines a weaker anchor than treated. 6. Both forecasters land exactly on 18% with no daylight between them despite claiming "independent" analysis and different confidence levels (0.55 vs 0.50) — this convergence to the same rounded number without any differing sub-model weight (e.g., one weighting empirical base rate more, another weighting CBO more) suggests insufficient diversity in the ensemble, reducing the value of having two forecasts at all.

18% (52% confidence)

Yes: 18% No: 82%

The Kalshi anchor (20%) and the 2000–2024 empirical hit rate for this exact 0.4pp band (20%) agree, which argues against a large deviation from market pricing. Offsetting that, institutional baselines (CBO ~1.8% for 2031–2036, Fed longer-run median 2.0%) center the distribution just below the band, and parametric models give only 7–11% in-band, so some downward shading is justified; the critique's point that 'No' captures both recession and boom tails reinforces this. The critique's counterpoints — that the +9pp move may reflect real information, that six years of forecast revisions make CBO/Fed a weak anchor, and that resolution-vintage ambiguity widens uncertainty — mostly argue for staying near the market rather than moving far from it, and largely cancel against the structural-slowdown case. I therefore finalize at 18% YES, a modest shade below the 20% market price, which is where both forecasters landed and where the balanced evidence supports.
