Planner reasoning

eBay's annual GMV has been roughly $73-75B in recent years, so hitting $92B in 2026 would require ~20%+ growth — far above eBay's recent low-single-digit GMV growth. The key research is establishing the current GMV run rate, 2025 quarterly trends, company guidance, and analyst expectations, plus the market's own price as anchor.

# Event Will eBay Inc. report Above $92 billion gross merchandise volume (GMV) for full-year 2026? # Outcomes to forecast - Yes (2026 GMV > $92B) - No (2026 GMV ≤ $92B) # Kalshi market anchor **Current YES price: 12%** (KXEBAYA-28JANGMV-92000000000.0). 7-day change: -2pp; 30-day change: +4pp. Avg daily volume ~986 contracts; 21-day price range 2%–14%. Market has drifted up over the month but pulled back recently — reflects modest, non-trivial probability being priced despite guidance implying a miss. # Sub-question answers 1. **FY2024/2025 GMV?** — FY2024 GMV was $74.7B (up 2% as-reported) [eBay IR]. FY2025 GMV rose ~7% YoY to $79.57B [MarketplacePulse]. 2. **Recent quarterly growth trend?** — Accelerating sharply: Q1'25 FX-neutral growth was ~2%, rising to Q1'26 GMV of $22.2B (+18% as-reported, +14% FX-neutral) and Q2'26 GMV of $22.4B (+15% YoY) [Octagon AI, Yahoo Finance, Investing.com]. Six-quarter trend shows consistent acceleration. 3. **Management guidance/analyst forecasts for 2026?** — After Q2'26 beat, eBay raised FY2026 GMV growth guidance to 11.5%–12.5% (up from prior 7%–7.5%) [Yahoo Finance]. Applied to the $79.57B 2025 base, this implies FY2026 GMV of roughly **$88.7B–$89.5B**, below the $92B strike at both ends. 4. **Structural drivers (Depop, AI, FX)?** — Depop acquisition closed July 30, 2026 ($1.4B cost), expected to add 1.5–2.5pp to GMV/revenue growth, with 2H26 growth accelerating by "double digits" for that unit [Quartr, Yahoo]. This is already embedded in the raised guidance, not incremental upside beyond it. 5. **Growth required for >$92B?** — From the $79.57B 2025 base, need ~+15.6% YoY growth minimum to clear $92B (vs. guided 11.5–12.5%). A code-execution model using an older/lower base ($73–76B) found required growth of +19.5–26% needed, 5.7–7.2 std devs above historical trend, yielding near-zero organic probability — though this analysis appears to use a stale/lower base than the confirmed $79.57B 2025 figure and predates the guidance raise. 6. **Adjacent Kalshi strikes?** — No related eBay/GMV markets found (kalshi_related and Polymarket both returned zero matches), so no cross-strike distribution is directly observable. # Key facts (high-confidence, factual) 1. [eBay IR] FY2024 GMV: $74.7B (+2% YoY as-reported). 2. [MarketplacePulse] FY2025 GMV: $79.57B (+7% YoY). 3. [Yahoo/Investing.com] Q1'26 GMV $22.2B (+18%); Q2'26 GMV $22.4B (+15%). 4. [Yahoo Finance] FY2026 guidance raised to 11.5–12.5% GMV growth post-Q2 beat — implies ~$88.7–89.5B full-year GMV. 5. [Investing.com] Q3'26 guidance: $22.0–22.4B GMV, 10–12% FX-neutral growth (consistent with full-year guide, not accelerating further). 6. [Quartr/Yahoo] Depop contributes ~1.5–2.5pp to growth, already factored into raised guidance. # Cross-market signals - Kalshi related: No other eBay GMV strike markets found; series appears to have only no-signal entries. - Polymarket: No matching markets. - Sportsbook implied: N/A (not applicable to this event type). # Analyst opinions and speculation - Claude-news synthesis: summing Q1+Q2 actuals (~$44.6B) plus Q3 guidance midpoint (~$22.2B) leaves ~$66.8B through 3 quarters; hitting $92B would require a Q4 of ~$25.2B (~25%+ YoY), far above the 10-12% guided pace — framed as a "stretch, above guidance" outcome. - Code-execution Monte Carlo (using a lower/stale ~$73-76B base and historical ~1-5% growth) estimated <1% probability, though this likely understates 2026's actual accelerating trajectory since it doesn't reflect the confirmed $79.57B 2025 base or the guidance raise. # Directional lean per outcome - **Yes (>$92B)**: Supported only by continued acceleration surprise (Depop upside, holiday season outperformance, FX tailwind) beyond raised guidance; opposed by explicit management guidance (11.5-12.5%) implying $88.7-89.5B, and Q3 guidance showing no further acceleration beyond ~10-12%. - **No (≤$92B)**: Strongly supported — official guidance, quarterly run-rate, and required Q4 growth (~25%+, historically unprecedented) all point to a shortfall versus $92B. # Gaps / unknowns - No confirmed Q4 2026 guidance or actual figure yet (event resolves on full FY2026 report, likely early 2027/2028 filing window per close date). - No adjacent Kalshi strike ladder to triangulate implied distribution shape. - Discrepancy between code-execution's lower baseline (~$73-76B) and confirmed $79.57B 2025 actual suggests the near-0% Monte Carlo estimate is likely too extreme/stale. # Calibration anchors - Kalshi current YES price: **12%** (anchor). - Guidance-implied 2026 GMV (~$88.7-89.5B) sits below strike; gap to $92B is ~$2.5-3.3B (~3-4pp of growth above high end of guidance) — a plausible but not high-probability beat, roughly consistent with low-teens Kalshi pricing rather than near-zero.

1. Both forecasters converge tightly around 8–11%, essentially anchoring to Kalshi's 12% with minor downward adjustments, but neither explores the tail-scenario math explicitly: even a "beat-and-raise" pattern (as seen in Q1/Q2 where actuals exceeded prior guidance by several points) applied to Q3/Q4 could plausibly push full-year growth into the 13-15% range, not just the guided 11.5-12.5%, which is understated in both rationales' probability mass. 2. Neither forecast interrogates the historical pattern of eBay's own guidance revisions this year — the prior guide was 7-7.5% and got raised to 11.5-12.5% after just one strong quarter, suggesting management guidance has been systematically conservative in 2026; this momentum/beat pattern deserves more explicit weight toward YES than a static "guidance implies $88.7-89.5B" framing suggests. 3. Both forecasters treat Q3 guidance (10-12% FX-neutral) as strong evidence against acceleration, but this is FX-neutral while the strike is nominal GMV — FX tailwinds (mentioned in the brief as a driver) could meaningfully widen the gap between FX-neutral and as-reported growth, which neither forecast quantifies despite flagging it as a factor. 4. Neither forecast addresses the "Gaps/unknowns" caveat that the event resolves on a distant close date (2028-03-31) with no confirmed Q4 2026 or full-year data yet — meaning substantial reporting/actual uncertainty remains that isn't just about growth-rate extrapolation, and this residual uncertainty arguably justifies a wider band than the tight 8-11% clustering. 5. Both forecasters dismiss the Monte Carlo's near-zero estimate as "stale," but neither considers that even after correcting the base to $79.57B, historical volatility/std-dev distance from trend growth might still argue for single-digit probability rather than the low-double-digit numbers chosen — the brief's own "5.7-7.2 std devs" framing (even if base-adjusted) suggests structurally low tail probability that both forecasts may be overweighting via pure guidance-gap arithmetic. 6. Neither forecaster discusses the lack of adjacent Kalshi strikes (fact #6) as a limitation on validating whether 12% is well-calibrated market pricing versus a thinly-traded, low-volume (~986 contracts/day) market prone to noise — both simply treat the Kalshi price as a reliable anchor without discounting for potential mispricing from illiquidity.

11% (70% confidence)

Yes: 11% No: 89%

Management's raised FY2026 guidance (11.5–12.5% growth on the $79.57B 2025 base) implies ~$88.7–89.5B, below the $92B strike, and clearing it requires ~15.6% full-year growth including an unprecedented ~25% Q4. However, the red-team correctly notes upside asymmetries the forecasters underweighted: guidance was already raised sharply once (from 7–7.5%), suggesting conservatism, and the strike is nominal GMV while Q3 guidance is FX-neutral — Q1 showed a 4pp FX tailwind (18% reported vs 14% FX-neutral) that could partially close the gap. These factors justify staying at the Kalshi anchor rather than shading below it as both forecasters did, but the required beat magnitude keeps this firmly a tail scenario. Final: 11% YES, aligned with market pricing.
