Planner reasoning

This asks whether eBay's full-year 2026 GMV exceeds $92B, which requires understanding eBay's recent GMV trajectory and growth rate. eBay's annual GMV has hovered in the $73-75B range recently, so $92B would require substantial growth—making the market anchor and eBay's reported financials the key inputs.

# Current state eBay reported Q1 2026 GMV of $22.2B (+14–18% YoY depending on source). Management raised full-year 2026 guidance to 7–7.5% FX-neutral GMV growth. Resolution requires full-year 2026 reported GMV to exceed $92B. # Timeline of key events - **2026-02-18** [confirmed] Q4 2025 earnings call: FY2025 GMV ~$79.57B; ~6% YoY growth; management signals continued momentum [Motley Fool transcript] - **2026-04-29** [confirmed] Q1 2026 earnings: GMV $22.2B, up 14–18% YoY; full-year GMV guidance raised to 7–7.5%; Q2 guidance 8–10% with expected deceleration [Yahoo Finance, DigitalCommerce360] - **2026-ongoing** Depop acquisition pending close by end-2026; expected to add ~1 pp to FX-neutral GMV growth [Yahoo Finance] --- # Event Will eBay report above $92 billion gross merchandise volume in full-year 2026? # Outcomes to forecast - **Yes**: Full-year 2026 GMV > $92B - **No**: Full-year 2026 GMV ≤ $92B # Kalshi market anchor **Current YES price: 9%** (KXEBAYA-28JANGMV-92000000000.0) - 7-day change: +4pp | 30-day change: +1pp - Avg daily volume: 1,703 contracts | Range: 3%–10% over 11 days - Recent upward drift likely driven by strong Q1 2026 beat, but market still prices low probability # Sub-question answers 1. **FY2024 and FY2025 GMV?** — FY2024: $74.67B; FY2025: ~$79.57B (+~6–7% YoY) [Marketplace Pulse, Motley Fool Q4 2025 transcript] 2. **Recent YoY GMV growth trend?** — FY2022: –15.7%, FY2023: –1.0%, FY2024: +1.9%, FY2025: ~+6.5%. Trend is recovery from 2021–2023 trough but still well below COVID peak. [Marketplace Pulse, code analysis] 3. **Management 2026 guidance?** — Full-year 2026 FX-neutral GMV growth guided at 7–7.5% (core) + ~1pp from Depop = ~8–8.5% total; Q2 expected to decelerate to 8–10% YoY [Yahoo Finance Q1 2026 earnings summary] 4. **Growth required to exceed $92B from 2025 base?** — ~+15.6% from $79.57B base; management guiding only 7–7.5%, roughly half the required rate [calculated] # Key facts (high-confidence, factual) 1. [Marketplace Pulse] FY2025 GMV: ~$79.57B; FY2024: $74.67B 2. [Yahoo Finance] Management FY2026 guidance: 7–7.5% FX-neutral GMV growth (ex-Depop) 3. [Yahoo Finance] Depop acquisition adds ~1pp to GMV growth when closed (expected end-2026) 4. [DigitalCommerce360] Q1 2026 GMV: $22.2B, +14–18% YoY (blowout quarter vs. guidance) 5. [Code analysis] At guided 7.5% + 1pp Depop (~8.5%), implied FY2026 GMV: ~$86.3B — $5.7B short of $92B 6. [Code analysis] Achieving $92B requires ~+15.6% growth from $79.57B base; eBay's historical single-year peak was +10.9% (2019→2020 COVID boost) 7. [Marketplace Pulse] eBay's all-time GMV peak was ~$100B in 2020; has never recovered to that level post-COVID # Cross-market signals - **Kalshi related**: No other eBay GMV markets found in related series; only this ticker active - **Polymarket**: No data found - **Sportsbook implied**: N/A # Analyst opinions and speculation - [Seeking Alpha] eBay outlined 10–12% GMV growth target for Q1 2026 specifically while advancing C2C strategy via Depop - [Yahoo Finance] Q2 deceleration expected as company laps prior-year marketing efficiencies and bullion volumes normalize - [fibre2fashion] Q1 beat driven partly by gold/silver bullion volumes and focus categories (collectibles, motors, fashion +24% combined); sustainability of 18% pace uncertain # Directional lean per outcome - **Yes (>$92B)**: Q1 2026 blowout (+18%) is a positive signal; if growth sustains near 15%+ for remaining 3 quarters, possible. Depop adds upside. Favorable macro for secondhand goods. - **No (≤$92B)**: Management explicitly guided only 7–7.5%; Q2 expected deceleration to 8–10%; even full-year 8.5% yields only ~$86B. No historical precedent for 15%+ growth absent COVID. Structural share loss to Amazon, Temu, Shein ongoing. # Gaps / unknowns - Q2–Q4 2026 actual results not yet available (Q1 is only reported quarter) - Depop acquisition timing and contribution size uncertain - Macro uncertainty (tariffs, European weakness) could pressure international GMV - Whether Q1 bullion/collectibles boom is durable or one-time # Calibration anchors - **Kalshi current YES price: 9%** (primary anchor) - At management guidance midpoint (7.25%), FY2026 GMV ~$85.3B — 7.7% below threshold - Required growth (~15.6%) exceeds eBay's best-ever modern growth rate (~10.9%) - Statistical model (normal distribution on recent growth) implies ~0.01% probability; Kalshi's 9% price implies meaningful model uncertainty premium - Q1 annualized run-rate: $22.2B × 4 = ~$88.8B — still below $92B even if all quarters matched Q1's pace

1. Both forecasters treat the Q1 annualized run-rate (~$88.8B) as a ceiling, but fail to account for the seasonal skew in eBay's GMV: Q4 is historically eBay's largest quarter due to holiday shopping, meaning a Q4 with even modest acceleration above Q1's pace could push the annual total meaningfully above the Q1×4 estimate. Neither forecaster quantified whether a Q4-weighted seasonal pattern could close the ~$3B gap. 2. Both forecasters accept management's 7–7.5% guidance as highly credible, but Q1 came in at 14–18% — roughly double the guided rate. The brief notes this as a "blowout quarter," yet neither forecaster explicitly stress-tests the scenario where Q1 is not an anomaly but signals a sustained re-acceleration driven by bullion/collectibles and focus categories, which would materially raise the Yes probability above 9%. 3. The Depop contribution is under-analyzed. Both forecasters note ~1pp from Depop, but the brief says the acquisition is "expected to close by end-2026," meaning Depop GMV may contribute for only a fraction of the year. Neither forecaster adjusted downward for the possibility that Depop adds far less than 1pp on a full-year basis if it closes in Q3 or Q4. 4. The statistical model cited in the brief ("normal distribution on recent growth implies ~0.01% probability") is dramatically below Kalshi's 9%, yet both forecasters land near 7% without reconciling this 700x gap. The correct diagnosis — that Kalshi's premium reflects model uncertainty and fat tails (e.g., M&A, macro tailwind) — is acknowledged but not quantitatively incorporated into either rationale. 5. Neither forecaster addresses the FX translation risk explicitly. Management guides "FX-neutral" growth at 7–7.5%, but reported GMV (what the resolution condition measures) could be materially different if the dollar strengthens against the euro and pound, where eBay has large exposure. A stronger dollar would widen the gap to $92B further, making Yes even less likely on a reported basis.

6% (50% confidence)

Yes: 6% No: 94%

The arithmetic gap is decisive: $92B requires ~15.6% growth from the $79.57B FY2025 base, more than double management's raised 7-7.5% guidance plus ~1pp Depop. Even annualizing the Q1 blowout ($22.2B×4=$88.8B) falls short, and Q4 seasonality would need to be extraordinary to close a ~$3-6B gap. FX translation risk cuts against reported GMV, and Depop likely contributes less than a full year. Both forecasters and the critique's upside scenarios don't overcome this, so I settle slightly below the Kalshi 9% anchor at 6%.
