Planner reasoning

This is a Kalshi question on MercadoLibre's reported annual 'items sold' metric for FY2026, reported in the Q4 2026 earnings release (~Feb 2027). The key is the historical trajectory of MELI's items sold (2022–2025) and the implied growth rate needed to exceed 3.0 billion in 2026. Market price on Kalshi is the anchor; earnings data and news fill in the quantitative base.

# Current state FY2025 items sold were reported at 2.429 billion (up 36% YoY from FY2024's 1.787B), per MELI's Q4'25 shareholder letter (SEC 8-K). Q1 2026 results (reported May 2026) showed items-sold growth accelerating further, with trailing-twelve-month items sold near 2.7B as of Q1'26. The market requires FY2026 full-year total to exceed 3.0B — a ~23.5% YoY increase over the 2.429B 2025 base, which recent quarterly trends suggest is achievable or likely to be exceeded. # Timeline of key events - 2023: Items sold grew 22% YoY for FY23; Q4'23 growth reached 29% YoY (confirmed, SEC 8-K). - 2024-02: FY2024 shareholder letter shows FY2024 items sold = 1.787B (confirmed, SEC/company). - 2025-Q1 (reported 2025-05): Items sold rose 28% YoY to 492M for the quarter (confirmed, MELI IR). - 2025-Q2: Items sold rose 31% YoY, driven by Mexico acceleration and lower Brazil free-shipping threshold (confirmed, company release). - 2025-Q3 (reported 2025-10-29, SEC 8-K): Brazil/Mexico items-sold growth accelerated to 42% YoY (confirmed). - 2025-Q4 / FY2025 (reported ~2026-02): FY2025 items sold = 2.429B total; Q4'25 items sold = 752M, up 43% YoY (accelerated from 39% in Q4'24) (confirmed, SEC 8-K/shareholder letter). - 2026-05-07: Q1 2026 results show items sold up 56% YoY (Brazil-led), FX-neutral GMV +38% YoY; trailing-12-month items sold ~2.7B (reported, BusinessWire/Quartr). - 2026-05 to 2026-07: Multiple analyst pieces (Motley Fool, Yahoo/StockStory) frame MELI's growth as accelerating despite stock volatility post-Q1 print (reported/speculative commentary, not primary data). # Event Will MercadoLibre report Above 3.0 billion items sold for FY2026 (resolves via FY2026 annual reporting, close 2028-03-31)? # Outcomes to forecast - Yes (>3.0B items sold in 2026) - No (≤3.0B items sold in 2026) # Kalshi market anchor Current YES price: **89%** (KXMELIA-28JANITEMS-3000000000.0). 7-day change: -1pt; 30-day change: -6pt (drifted down from ~95-98% range). Avg daily volume: 842 contracts. Price range over 12 data points: 88-98%. Market has softened modestly but remains strongly YES-leaning. # Sub-question answers 1. **FY items sold 2022-2025**: FY2024 = 1.787B; FY2025 = 2.429B (confirmed, SEC 8-K/shareholder letter). FY2023 implied ≈1.46-1.57B depending on source; FY2022 implied ≈1.10B (code_execution estimate, not directly sourced). Quarterly 2025: Q1=492M, Q2≈752M cumulative-implied, Q3 (Brazil/Mexico +42% YoY), Q4=752M (43% YoY). 2. **YoY growth trend**: FY2025 grew 36% YoY over FY2024. Contrary to code_execution's decelerating-trend assumption, actual quarterly data shows *acceleration* through 2025 (Q4'24 39% → Q4'25 43%) and further acceleration into Q1'26 (56% YoY reported for items sold, claude_news/BusinessWire). 3. **Required 2026 growth**: From 2.429B base, exceeding 3.0B requires ~+23.5% YoY growth — well below the 36-56% growth rates observed in the most recent quarters. 4. **Metric definition changes**: No evidence found of a redefinition of "items sold"; company continues reporting it consistently alongside GMV in shareholder letters (claude_news). 5. **Macro/competitive factors**: Lower free-shipping thresholds in Brazil, Mexico share gains, and logistics network expansion (Mercado Envios, 96% managed network, 76% delivered within 48hrs per Q1'26 letter) are cited as accelerants; no Shein/Temu/Amazon countervailing pressure was found in research (silent). 6. **Kalshi distribution**: Only the >3B bucket was retrieved (89%); no adjacent-threshold data found (polymarket_related returned 0 matches; kalshi_related returned only this same market). # Key facts (high-confidence, factual) 1. [SEC 8-K, stocktitan] FY2025 items sold = 2.429B; FY2024 = 1.787B (36% YoY growth). 2. [SEC 8-K Q3'25] Brazil/Mexico items-sold growth accelerated to 42% YoY in Q3'25. 3. [BusinessWire/Quartr, 2026-05-07] Q1'26 items sold +56% YoY; trailing-12-month ≈2.7B as of Q1'26. 4. [Kalshi direct] Current YES price 89%, down from 95-98% range over past 30 days. # Cross-market signals - Kalshi related: no adjacent threshold markets found (only the >3B bucket itself surfaced). - Polymarket: no matching markets (0/100 scanned). - Sportsbook implied: N/A (not applicable to this event type). # Analyst opinions and speculation - Multiple Motley Fool/Yahoo pieces (2026-05 to 2026-07) are bullish on MELI's growth trajectory post-Q1'26, citing "fastest revenue growth in almost four years" and market-share gains (reported, directionally supports Yes but is stock-commentary, not a direct items-sold forecast). - Motley Fool (2026-07-26) suggests market may be mis-focused on wrong metrics, implying underlying volume growth is stronger than price action suggests. # Directional lean per outcome - **Yes**: Supported by accelerating actual growth (36% FY25, 43% Q4'25, 56% Q1'26 YoY) against only a 23.5% growth requirement; trailing-12-month already at 2.7B by Q1'26. Kalshi at 89% reflects this strength. - **No**: Supported only by a generic mean-reversion/deceleration prior (code_execution's model assumed slowing growth, yielding 15-30% Yes probability) — but this model relied on stale/lower 2025 base assumptions (2.3-2.5B) inconsistent with the actual reported 2.429B and ignored the Q1'26 acceleration data, weakening its credibility. # Gaps / unknowns - No official 2026 full-year guidance number cited directly by management (only quarterly trend data). - Full Q2-Q4 2026 data not yet available (event resolves after FY2026 close). - Adjacent Kalshi thresholds (e.g., >2.5B, >3.5B) not retrieved, limiting distribution-shape inference. # Calibration anchors - Kalshi current YES price: **89%** (primary anchor). - Required 2026 growth (+23.5%) is below trailing recent quarterly growth rates (36-56%), supporting a Yes lean modestly above or in line with Kalshi's 89%. - Precedent: MELI has beaten prior-year growth expectations in 6 of last 8 quarters cited, with no deceleration below 28% YoY since 2024.

1. Both forecasters converge tightly (93%/92%) just above Kalshi's 89%, but neither explores why the market itself has drifted down 6-9 points over 30 days despite accelerating fundamentals — this divergence between market action and data deserves more explicit scrutiny (e.g., is there information the market has that the brief doesn't, like FX/currency devaluation risk in Brazil/Argentina that could suppress unit volumes even as GMV grows)? 2. Neither forecast addresses the arithmetic sensitivity fully: TTM ~2.7B as of Q1'26 means only ~300M incremental items needed over three quarters (Q2-Q4'26) versus a 2025 comparable base of ~1.937B for those same quarters — implying required growth is closer to single digits, not "mid-teens" as Forecast 2 states, which suggests both may be *underestimating* the true Yes case rather than overestimating it. 3. Both cite "Temu/Shein/Amazon competitive pressure" as a residual No-case driver, but the brief explicitly states "no Shein/Temu/Amazon countervailing pressure was found in research (silent)" — this is treating an absence of evidence as a live risk without justification, inflating the No probability artificially. 4. Neither forecaster addresses currency/macro risk specific to LatAm (Argentina inflation/devaluation, Brazil FX swings) which could distort GMV-based commentary but also potentially affects logistics capacity or reported unit counts if promotional/free-shipping thresholds are adjusted — this is a plausible tail scenario absent from both rationales. 5. Both treat the Kalshi price as a fuzzy anchor to nudge only slightly above (89%→92-93%) rather than interrogating whether the required growth math (only ~23.5% YoY, well below trailing 36-56% rates with accelerating not decelerating trend) justifies a much higher probability (e.g., mid-to-high 90s) — the "modest nudge above market" approach may reflect anchoring bias rather than the strength of the data itself. 6. Neither forecast discusses the resolution timing risk: the event closes 2028-03-31, two years after FY2026 ends, so there's ample buffer for restatements or definitional clarifications, but also no discussion of what happens if MELI changes reporting format (e.g., stops breaking out "items sold" separately from GMV) — the brief flags this as a genuine unknown ("No official 2026 full-year guidance number cited directly by management") that neither forecast weights as a distinct tail risk beyond a passing mention.

94% (medium confidence)

Yes: 94% No: 6%

Doing the arithmetic cleanly: FY2025 = 2.429B with Q1'25 = 492M, so Q2-Q4'25 = 1.937B; Q1'26 at +56% ≈ 767M, leaving ~2.233B needed in Q2-Q4'26, i.e., only ~15% YoY growth versus 40-56% actually being posted — Forecast 2's 'mid-teens' framing is correct and the critique's 'single digits' claim mis-uses the TTM figure. Even a severe deceleration to the low-to-mid teens clears 3.0B, and the trend is accelerating (Q4'25 +43%, Q1'26 +56%) with structural drivers (Brazil free-shipping threshold, Mexico share gains, logistics buildout). The critique is right that residual competitive pressure from Temu/Shein is asserted without evidence and that anchoring at 89% may understate the math, so I move slightly above both forecasters. I retain ~6% for genuine tails: a sharp LatAm macro/FX shock, a change in how 'items sold' is disclosed or defined, or ambiguity in the resolution source.
