Planner reasoning

This Kalshi market asks about Carnival Corporation's 2026 available lower berth days (ALBD) capacity exceeding 97.3M. ALBD is reported in earnings; I need Kalshi anchor, Carnival's reported/guided capacity, and fleet growth news.

# Event Will Carnival Corporation report Above 97.3 million available lower berth days (ALBD) in FY2026? # Outcomes to forecast - **Yes**: FY2026 ALBD > 97.3 million - **No**: FY2026 ALBD ≤ 97.3 million # Kalshi market anchor **Current YES price: 81%** — up +4pp over 7 days, +5pp over 30 days. Range over observed period: 76–83%. Volume: ~702 contracts/day. Strong upward drift suggests informed buyers are pricing in above-threshold ALBD. # Sub-question answers 1. **Current Kalshi market price** — 81% YES [Kalshi direct]. Trending upward recently. 2. **Carnival's 2025 ALBD and 2026 guidance** — No explicit FY2026 ALBD figure disclosed. FY2024 ALBD ~90.0M (actual); FY2025 estimated ~93–94M based on analyst/model estimates. Q1 FY2026 results (March 2026) confirmed record revenues and strong demand but did not state a full-year ALBD number. [SEC 8-K, Cruise Industry News] 3. **New ships 2025–2026 capacity impact** — Carnival has 6–8 contracted newbuilds across 2025–2027 pipeline (~3,000 berths each), adding ~0.3–0.4% per ship to annual ALBD. Delivery timing is key variable. [code_execution model] 4. **Historical ALBD YoY growth** — FY2023→2024: +4.05%; FY2024→2025 (est.): ~+3.89%. Post-COVID recovery phase; growth deliberately "measured" under PROPEL strategy. [code_execution] 5. **Ship retirements/disruptions** — No specific retirements or major disruptions identified for 2026. PROPEL strategy emphasizes midlife refurbishment, not fleet reduction. Capacity growth intentionally restrained to let demand outpace supply. [SEC 8-K] # Key facts (high-confidence, factual) 1. [SEC 8-K, Mar 2026] Q1 FY2026 revenues record $6.2B; ~85% of 2026 already booked at record prices. 2. [PR Newswire Jun 2025] Carnival exceeded its 2026 SEA Change ROIC/EBITDA-per-ALBD targets 18 months early. 3. [Cruise Industry News] FY2026 adjusted cruise costs ex-fuel per ALBD guided +~3.1% vs. 2025 — implies ALBD denominator is growing. 4. [code_execution] Reaching 97.3M from a 93.5M base requires ~4.06% growth — essentially exactly the historical mean. 5. [code_execution] From 94.0M base (high-end 2025), only ~3.51% growth needed; from 93.0M base, ~4.62% needed. 6. [Kalshi] Market has been rising toward 81% over the past month, implying market participants believe 2025 base is likely closer to the high end. # Cross-market signals - **Kalshi related**: Only market identified is the one being forecast (KXCCLA-28JANALBD-97300000.0) at 81%. No adjacent ALBD bucket markets found. - **Polymarket**: No matching markets found. - **Sportsbook**: N/A. # Analyst opinions and speculation - PROPEL strategy language ("demand outpaces intentionally measured capacity growth") suggests Carnival is deliberately not over-expanding fleet — slight headwind to hitting a growth-dependent threshold. [SEC 8-K] - Strong customer deposit record ($8.5B) and booking trends suggest high utilization, which boosts ALBD indirectly through fewer idle days. [Morningstar/PR Newswire] - Monte Carlo (mean 4.0% growth, σ=0.8%, 2025 base ~93.5M±1M) yields central 2026 ALBD of ~97.24M — just *below* 97.3M, giving ~45–50% probability under neutral assumptions. [code_execution] - The Kalshi market at 81% implies the market believes the 2025 base is likely ~94M+ or growth will modestly exceed historical mean. # Directional lean per outcome - **Yes (>97.3M)**: Supported by strong booking/revenue trends, ~4% historical growth, newbuild pipeline, high fleet utilization, rising Kalshi price (81%). If FY2025 ALBD lands at 94M+, only ~3.5% growth needed. - **No (≤97.3M)**: Supported by "measured capacity growth" strategy, threshold sitting almost exactly at historical mean (coin-flip under neutral model), and risk that FY2025 base comes in at low end (~93M), requiring ~4.6% growth. # Gaps / unknowns - No explicit FY2026 full-year ALBD guidance number publicly disclosed. - FY2025 actual ALBD (year-end Nov 2025) not yet confirmed in research — dominant uncertainty driver. - Newbuild delivery schedule specifics and drydock timing unconfirmed. - Whether "2026" means calendar year or FY ending Nov 30, 2026 affects resolution. # Calibration anchors - **Kalshi current YES price: 81%** (primary anchor; trending up) - **Neutral model estimate: ~45–50%** (from 93.5M base, 4.0% mean growth) - **High-base scenario (~94M 2025)**: ~70–73% probability - **Historical growth range**: 3.9–4.1% recently; threshold requires ~4.1% from midpoint base - Kalshi's 81% implies the market is pricing in a higher-than-neutral 2025 base or growth rate — consistent with the strong Q1 FY2026 operating results

1. Both forecasters discount the Kalshi anchor (81%) by 2–7pp citing the neutral Monte Carlo model (~45–50%), but the brief explicitly flags that the neutral model uses a midpoint 2025 base of 93.5M — while strong Q1 FY2026 operating results, $8.5B in deposits, and rising Kalshi price collectively suggest the market is already pricing a higher-end 2025 base (~94M+), which alone lifts the probability to ~70–73% before any growth premium. 2. Neither forecaster adequately weighs the directional signal embedded in the cost-per-ALBD guidance: the brief notes FY2026 adjusted cruise costs ex-fuel per ALBD are guided +~3.1% vs. 2025, which implies Carnival's own internal planning embeds a growing ALBD denominator — a form of implicit guidance that both forecasters treat only superficially. 3. Both forecasters treat the "measured capacity growth" (PROPEL strategy) language as a headwind without noting the brief's key fact that Carnival exceeded its 2026 SEA Change targets 18 months early — suggesting operational execution has been running ahead of plan, which undermines the bearish read on intentional capacity restraint. 4. The dominant uncertainty driver — the actual FY2025 ALBD (year-end Nov 2025) — is unresolved, yet neither forecaster explicitly models the asymmetry: the brief states the rising Kalshi price implies informed participants believe the 2025 base is near the high end, and neither forecaster assigns explicit probability weights to the low-base vs. high-base 2025 scenarios before aggregating. 5. Neither forecaster flags the calendar year vs. fiscal year (ending Nov 30, 2026) ambiguity noted in the brief as a potential resolution risk — a misalignment could shift ALBD by several percentage points and change the outcome materially. 6. Forecast 2's rationale partially double-counts the Kalshi discount: it invokes the neutral model's coin-flip as justification for discounting to 74%, but the brief is explicit that the neutral model's central estimate (97.24M) is *below* the 97.3M threshold, meaning under the neutral model the correct probability is actually below 50% — not a modest discount from 81%, making a 74% estimate implicitly more bullish on the 2025 base than the rationale acknowledges.

79% (50% confidence)

Yes: 79% No: 21%

Anchoring near the Kalshi market (81%) which has trended up on strong Q1 FY2026 results, 85% booked, and cost-per-ALBD guidance implying a growing denominator. Slight discount for neutral-model risk that the FY2025 base lands at the low end.
