Planner reasoning

This is a numeric corporate-metric question: whether Carnival's FY2026 available lower berth days (ALBDs) exceed 97.3 million. The key is the historical ALBD trajectory (FY2023-FY2025 actuals) plus Carnival's own FY2026 capacity guidance and newbuild/retirement schedule, which the company reports explicitly in earnings releases. I'll anchor on the Kalshi market ladder (other strikes in the same event imply a distribution) and supplement with earnings/news research and arithmetic extrapolation.

# Current state Carnival Corp is roughly two-thirds through FY2026 (fiscal year ends Nov 30, 2026) with actual Q1 and Q2 ALBD figures already reported showing modest (+0.5% to +2.0%) YoY capacity growth. The Kalshi contract resolves based on Carnival's officially reported full-year 2026 ALBD figure (expected in the FY2026 10-K/Q4 earnings release, likely Dec 2026); no final FY2026 total exists yet. # Timeline of key events - 2025-09: New Princess Cruises ship enters service, adding FY2026 Q1 capacity (confirmed, SEC 10-Q ccl-20260228.htm). - 2025-Q3 (Aug): P&O Australia ship exits fleet; Seabourn exit noted in FY2025 filings, pressuring FY2025 Q3 ALBD down 2.5% YoY (confirmed, 10-Q ccl-20250831.htm). - 2025-summer: Carnival decided to redeploy away from previously planned Q1 2026 Arabian Gulf voyages (confirmed, 8-K). - 2025-Dec: FY2026 guidance issued — net yields +~2.75%, adjusted costs ex-fuel/ALBD +~3.1% (constant currency), implying low-single-digit capacity growth (confirmed, 8-K a20261qearningsrelease8-k.htm). - 2026-Q1 (through Feb 28, 2026): ALBDs +0.5% YoY, driven by new Princess ship, offset by P&O Australia exit and more Europe dry-dock days (confirmed, 10-Q). - 2026-Q2 (through May 31, 2026): ALBDs 24.7M (+2.0% YoY); six-month cumulative 48.4M vs 47.8M (+1.2%) (confirmed, 10-Q ccl-20260531.htm). - 2026-06-23: Q2 FY2026 earnings — record revenues/yields; company reiterating/raising guidance (confirmed, PRNewswire/8-K). - 2026-07-10: Steel cut for new "Carnival Destiny" mega ship; no FY2026 delivery impact (delivery years away) (confirmed, Maritime Executive). - 2026-06-25: Newbuild programme extended into 2030s, incl. new AIDA ships for FY2030/2032 — no FY2026 capacity effect (confirmed, PRNewswire/travelextra). # Event Will Carnival Corporation's full-year 2026 reported Available Lower Berth Days (ALBD) exceed 97.3 million? # Outcomes to forecast - Yes (Above 97.3 million) - No (97.3 million or below) # Kalshi market anchor Current YES price: **77%** (KXCCLA-28JANALBD-97300000.0). 7-day change: -2pp; 30-day change: +1pp. Range over past 25 days: 76%-87% (has drifted down from a peak near 87%). Avg daily volume: 331 contracts (thin but consistent). This is the consensus to beat. # Sub-question answers 1. **FY2023/24/25 ALBDs** — Exact full-year totals not directly retrieved; only quarterly/YoY deltas available. Estimated trajectory (code_execution model): FY2023 ~89.3M, FY2024 ~92.0M, FY2025 ~94–96M (mid-estimate ~94.5–96M), reflecting a ~2–3% historical annual growth rate. **Gap: precise 10-K figures not confirmed.** 2. **FY2026 guided/implied growth** — Dec 2025 guidance implied low-single-digit capacity growth (cost/yield guidance framed around ~2.75-3.1% metrics, not a direct ALBD % line). Actuals to date: Q1 +0.5% YoY, Q2 +2.0% YoY, H1 cumulative +1.2% YoY (SEC 10-Qs). At ~1.2-2% growth off a ~96M FY2025 base, FY2026 would land ~97.2-98.0M — straddling the 97.3M threshold. 3. **Ship entries/exits FY2026** — One new Princess ship (delivered Sept 2025) adds capacity into FY2026; P&O Australia ship exited (FY2025/26 transition); no major FY2026 newbuild deliveries beyond that (next big ship "Carnival Destiny" — steel cut July 2026, delivery post-2026). AIDA newbuilds not due until FY2030/2032 (claude_news, gdelt_news). 4. **Kalshi ladder / distribution** — Only this single strike (97.3M) surfaced in related-market scans; no adjacent strikes found to triangulate the full distribution. Market's 77% YES suggests the central estimate for FY2026 ALBD sits somewhat above 97.3M, but not with high confidence (price range 76-87% shows meaningful uncertainty/repricing). 5. **Dry-dock/geopolitical risks** — Explicitly flagged: more Europe dry-dock days scheduled in 2026 (drag on ALBD); Arabian Gulf Q1 2026 voyage redeployment (mix shift, not necessarily ALBD-reducing) (SEC 10-Q/8-K). No Red Sea/Caribbean capacity-loss events reported. 6. **Historical guidance accuracy** — Not directly quantified in research; company has a track record of hitting/slightly beating "SEA Change" targets 18 months early (news-journal.com, June 2026), suggesting operational execution has recently trended better than plan, a mild positive signal for capacity/yield delivery. # Key facts (high-confidence, factual) 1. [SEC 10-Q] FY2025 H1 ALBD = 47.8M (Q1 23.6M, Q2 24.2M). 2. [SEC 10-Q] FY2026 H1 ALBD = 48.4M (Q1 +0.5%, Q2 24.7M/+2.0% YoY); cumulative H1 growth +1.2%. 3. [SEC 10-Q] FY2025 Q3 ALBD fell 2.5% YoY due to ship exits (Seabourn, P&O Australia); nine-month FY2025 ALBD still +0.9% YoY. 4. [PRNewswire/news-journal] Carnival topped Q2 FY2026 guidance, exceeding "SEA Change" 2026 targets 18 months early. 5. [Kalshi direct] YES price 77%, down from a 30-day high of 87%. # Cross-market signals - Kalshi related: No adjacent ALBD strikes found to build a full probability curve; only this single market surfaced. - Polymarket: No Carnival/cruise-specific markets exist; unrelated "cruise" keyword hits were Iran-ceasefire markets (irrelevant). - Sportsbook implied: N/A. # Analyst opinions and speculation - code_execution model (independent estimate): P(ALBD>97.3M) weighted ~71%, noting the threshold sits almost exactly at a 3% YoY growth scenario off FY2025 base — highly sensitive to exact growth rate achieved. - Financial media (Fool.com, Insidermonkey) generally bullish on Carnival's 2026 operating momentum but do not address ALBD specifically. # Directional lean per outcome - **Yes (>97.3M)**: Supported by record Q2 results, guidance beats, positive H1 cumulative growth (+1.2%), one incremental Princess ship, and Kalshi's 77% pricing. - **No (≤97.3M)**: Supported by decelerating quarterly growth pattern in FY2025 (Q3 -2.5%), added Europe dry-dock days in 2026, ship exits (P&O Australia, Seabourn), and no major FY2026 newbuild deliveries beyond the single Princess ship — H1 growth of only +1.2% is below the ~3% pace implied to clear the threshold from a ~94-95M FY2025 base. # Gaps / unknowns - Exact FY2025 full-year reported ALBD (needed as the base for FY2026 comparison) not directly confirmed from 10-K. - No H2 FY2026 (Q3/Q4) actuals yet; full-year outcome hinges on Q3/Q4 dry-dock schedule and any further redeployment. - No adjacent Kalshi strikes to infer full market distribution shape. # Calibration anchors - Kalshi current YES price: **77%** (primary anchor). - Historical ALBD growth has run ~2-3%/year; FY2026 H1 actual growth (+1.2%) is running below that historical average, a mild bearish signal relative to the 77% price. - Independent model estimate: ~65-75% probability range, roughly consistent with Kalshi pricing.

1. Both forecasters lean heavily on an unconfirmed FY2025 base (~94-96M) and a straight-line annualization of H1 growth (+1.2%), but the brief explicitly flags FY2025 Q3 fell -2.5% YoY due to ship exits — this creates an easier H2 comp that could push growth well above the H1 rate, an upside dynamic neither forecast quantifies with a concrete H2 estimate (they only gesture at "2-3% toward H2"). 2. Neither forecast addresses the sensitivity/asymmetry point raised in the brief that the threshold "sits almost exactly at a 3% YoY growth scenario" — given this knife-edge positioning, a wider spread or more explicit scenario-weighting (e.g., P(growth<1%), P(1-2%), P(2-3%), P(>3%)) would be more informative than a single point estimate converging near consensus. 3. Both forecasters shade slightly below the 77% Kalshi anchor (74% and 72%) for essentially the same stated reason (unconfirmed base, sub-trend H1 growth), producing redundant, correlated forecasts rather than independent triangulation — neither explores whether Kalshi's own drift from 87%→77% over 30 days might reflect information they're missing (e.g., a specific H2 dry-dock disclosure) versus just noise in a thin (331 contracts/day) market. 4. Neither forecast considers the "beat guidance" signal (Fact 4: Carnival topped Q2 guidance and exceeded SEA Change targets 18 months early) as directly bearing on the probability of exceeding capacity/yield targets — this execution-beat pattern is a positive lean that both forecasts mention only in passing without translating into upward pressure on their Yes probability. 5. Both estimates cluster tightly (0.72-0.74) with the same reasoning, suggesting anchoring bias to Kalshi/each other rather than independent modeling; given how many key unknowns remain unresolved (unconfirmed FY2025 base, no H2 actuals, no adjacent strikes to infer distribution shape), a starker range or higher uncertainty (e.g., wider confidence intervals, more No-side probability given the arithmetic straddle) would better reflect the genuinely unresolved state of evidence. 6. Neither forecaster explicitly addresses the Arabian Gulf redeployment (mix-shift away from planned voyages) as a potential ALBD-neutral vs ALBD-reducing event — the brief notes this is "not necessarily ALBD-reducing" but leaves ambiguity that could matter for Q1's soft +0.5% figure and hasn't been resolved by either analysis.

75% (53% confidence)

Yes: 75% No: 25%

Bottom-up reconstruction: FY2025 full-year ALBD likely ~95.3–96.0M (H1 47.8M, Q3 down 2.5% on ship exits, Q4 roughly flat), so clearing 97.3M in FY2026 requires ~1.5–2.0% full-year growth. H1 FY2026 delivered +1.2% (48.4M), leaving H2 needing ~2.0–2.5% — achievable given genuinely easier comps (FY2025 H2 absorbed the P&O Australia/Seabourn exits) and a full-period contribution from the new Princess ship, but not assured given extra Europe dry-dock days and no further FY2026 deliveries. The critique is right that the easier H2 comp is a real upside dynamic both forecasters under-weighted, and that Carnival's recent guidance-beating execution leans mildly positive; these offset the sub-trend H1 print that motivated both to shade below market. Given the arithmetic straddle and thin-market noise (77% after drifting from 87%), I settle essentially at the Kalshi anchor rather than below it, with meaningful No mass reflecting the knife-edge base uncertainty.
