Sub-questions (Fermi decomposition)

What was MercadoLibre's total items sold in full-year 2025 and the Q4 2025 quarterly run-rate?
What has the year-over-year growth rate in items sold been over the last 4-8 quarters (e.g., 2024 ~1.8B, 2025 ~?)?
What growth in items sold would be required in 2026 to exceed 3.6B, and how does that compare to analyst/company expectations for 2026 unit or GMV growth?
Did MercadoLibre report any acceleration drivers in 2026 (e.g., lower free-shipping thresholds in Brazil, Argentina recovery, Mexico expansion) that could boost unit growth to 50%+?
How does Kalshi price the adjacent thresholds in the KXMELIA-28JANITEMS ladder (e.g., 3.0B, 3.3B, 3.9B), and does the implied distribution align with the 3.6B price?
Has MercadoLibre already reported any 2026 quarterly results (Q1-Q3 2026) showing the year-to-date items sold pace?

Planner reasoning

MercadoLibre reports items sold (GMV units) quarterly; 2024 was ~1.8B items and 2025 ran roughly 25-30% higher (~2.3B). Reaching 3.6B in 2026 would require ~55%+ growth over 2025, which is well above recent trends, so the key questions are the actual 2025 run-rate, 2026 guidance/analyst growth expectations, and how Kalshi prices the item-count ladder.

# Current state MercadoLibre's 2026 full-year "items sold" figure will not be finalized/reported until Q4 2026 earnings (expected Feb 2027), well before the market's March 2028 close. The resolution depends on total company-wide 2026 units, not any single quarter or one-country data point. As of the latest disclosed data (Q1 2026), consolidated company-wide items sold for 2026 has not been explicitly reported — only a Brazil-segment breakout (+56% YoY) is available, alongside an EPS miss for Q1 2026. # Timeline of key events - 2024-Q4: Items sold 525.5M, +27% YoY (confirmed, Quartr/MELI IR). - 2025-Q1: Items sold 492M, +28% YoY (confirmed, MELI IR). - 2025-Q2: Items sold 550.1M, +31% YoY (confirmed, MELI IR release). - 2025-Q3: Items sold 635M, +39% YoY (confirmed, MELI IR release). - 2025-Q4: Items sold ~751M (est.), +43% YoY, implying FY2025 total ~2.4B items (reported/estimated, levelheadedinvesting + mexicobusiness.news; exact company-stated unit figure not directly quoted). - 2026-Q1 (reported 2026-05-07/08): Brazil segment items sold +56% YoY, GMV +38% FX-neutral, fastest revenue growth in ~4 years (confirmed, Businesswire); but consolidated Q1 2026 EPS ($8.23) missed estimates ($8.50) and operating margin (6.9% vs 7.7% est.) disappointed, stock fell ~12% (confirmed, CNBC 2026-05-08). Company-wide items-sold total for Q1 2026 not disclosed in available research. # Event Will MercadoLibre report Above 3.6 billion items sold in full-year 2026? # Outcomes to forecast - Yes (Above 3.6B) - No (3.6B or below) # Kalshi market anchor Current YES price: **24%**. Trend: +15% over 7 days, +16% over 30 days (started as low as 7%), average daily volume ~679 contracts over 10 data points — indicating rising but still minority-probability sentiment, likely driven by strong Q1 2026 Brazil growth data despite the EPS miss. # Resolution source Not run / not present in research (no dedicated resolution_source fetch). # Sub-question answers 1. **FY2025 items sold and Q4 run-rate** — FY2025 items sold ≈2.4B (sum of quarterly figures: 492M+550.1M+635M+~751M est.); Q4 2025 run-rate ~751M units/quarter (+43% YoY), per MELI IR releases and levelheadedinvesting (est.). 2. **YoY growth trend (last 4-8 quarters)** — Accelerating: Q4'24 +27%→Q1'25 +28%→Q2'25 +31%→Q3'25 +39%→Q4'25 +43% (claude_news/MELI IR). 2023→2024 full-year growth was ~22.6%, 2024→2025 ~28-36% depending on base assumption (code_execution vs claude_news). 3. **Growth required for 3.6B in 2026** — Needs ~50-57% YoY growth from a 2025 base of 2.3-2.4B items (code_execution: 56.5% from 2.3B; claude_news: ~48% from 2.43B). This exceeds even the fastest recent quarterly pace (43% in Q4'25) by a meaningful margin; no formal company unit guidance exists for 2026 (claude_news). 4. **2026 acceleration drivers** — Q1 2026 Brazil segment showed items sold +56% YoY and GMV +38% FX-neutral, described as fastest revenue growth in ~4 years, attributed to strategic investments/market share gains (Businesswire, 2026-05-07). No explicit mention of free-shipping threshold cuts, Argentina recovery, or Mexico expansion as named drivers in available research. 5. **Kalshi ladder alignment** — Only the 3.6B bucket data was returned; no data on 3.0B/3.3B/3.9B adjacent buckets from kalshi_related tool (0 matches found). Cannot directly verify distribution consistency, but code_execution's simulated distribution (mean 2.87B, 90% CI 2.58-3.19B) implies the market's 24% YES price is far more bullish than a naive historical-trend model, which assigns <1% probability to exceeding 3.6B. 6. **2026 quarterly reports already released** — Only Q1 2026 has been reported (as of research date); Q2/Q3 2026 not yet available. Q1 2026 showed consolidated EPS miss and margin compression, but strong Brazil-specific unit/GMV acceleration (CNBC 2026-05-08; Businesswire 2026-05-07). # Key facts (high-confidence, factual) 1. [MELI IR/claude_news] FY2025 items sold ≈2.4B, up from ~1.79B in 2024 (~34-36% YoY). 2. [claude_news] Quarterly YoY items-sold growth accelerated each quarter in 2025: 28%→31%→39%→43%. 3. [code_execution] Reaching 3.6B in 2026 requires ~50-57% YoY growth — roughly 1.3-2x the fastest 2025 quarterly pace. 4. [CNBC 2026-05-08] Q1 2026 consolidated EPS ($8.23) missed estimates ($8.50); operating margin fell to 6.9% vs 7.7% expected; stock fell ~12%. 5. [Businesswire 2026-05-07] Brazil segment (largest market) saw items sold +56% YoY in Q1 2026 — an acceleration if representative of the whole company, but only one segment's data is confirmed. # Cross-market signals - Kalshi related: No adjacent-threshold data found (0 related markets returned). - Polymarket: No MercadoLibre/MELI markets found. - Sportsbook implied: N/A (not a sports event). # Analyst opinions and speculation - code_execution's statistical model (lognormal simulation, 25% mean/8% std growth) assigns <0.1% probability to exceeding 3.6B — implying the 24% Kalshi price is far more optimistic than a naive trend extrapolation. - Levelheadedinvesting and mexicobusiness.news frame 2025 growth as record-setting and accelerating, supporting bullish narratives, but neither explicitly forecasts 2026 unit totals. - MELI does not issue formal unit-sales guidance (claude_news), leaving 2026 projections speculative. # Directional lean per outcome - **Yes (>3.6B)**: Supported by accelerating YoY trend (28%→43%) and strong Q1 2026 Brazil segment (+56%) suggesting momentum could continue; Kalshi price has risen sharply (7%→24% in 30 days). Opposed by: required growth (~50-57%) is unprecedented for the company, EPS miss/margin compression in Q1 2026 signals cost pressure that could constrain aggressive volume-chasing, and no confirmed company-wide (not just Brazil) acceleration to that magnitude. - **No (≤3.6B)**: Supported by historical growth ceiling (~40-45% max quarterly rate), lack of formal guidance, quantitative modeling showing this as a statistical tail event, and mixed Q1 2026 results (margin miss). Opposed by: recent trend acceleration and Brazil data point suggesting further upside surprise is plausible. # Gaps / unknowns - No confirmed company-wide (consolidated, not just Brazil) items-sold figure for Q1 2026 or later 2026 quarters. - No visibility into Kalshi's adjacent bucket pricing (3.0B, 3.3B, 3.9B) to validate implied distribution shape. - Exact 2024 and 2025 full-year items-sold totals are estimates/back-calculations, not confirmed single-figure company disclosures. # Calibration anchors - Kalshi current YES price: **24%** (up from 7% a month ago — anchor, reflects rising but still minority sentiment). - Historical precedent: quarterly items-sold growth has never exceeded ~45% YoY in recent data; achieving 50-57% full-year growth would be a record-breaking acceleration beyond any observed quarter.

FY2025 items sold sum to ~2.43B, so 3.6B requires roughly 48% full-year growth versus a Q4'25 peak of +43% and an accelerating quarterly trend (28%→31%→39%→43%). Q1 2026 Brazil items sold +56% suggests consolidated growth near 45-50% is plausible, and a back-of-envelope path (~740M/825M/940M/1.09B) lands right around 3.55-3.6B, making this a genuine coin-flip-adjacent threshold rather than the <1% tail a naive 25%-growth model implies. Sustaining ~48% through tough Q3/Q4 comps while margins are compressing (Q1 EPS miss, 6.9% op margin) is a real headwind, and only one segment's unit data is confirmed. Kalshi at 24% (up from 7%) has priced in the Q1 momentum; I lean slightly above the anchor given Brazil's outsized weight and sub-50% growth already nearly sufficient.

FY2025 items sold sum to ~2.43B (492M+550M+635M+~751M), so >3.6B requires roughly 48-50% full-year growth sustained across 2026 against progressively tougher comps (Q4'25 base already +43%). The trend is clearly accelerating (28%→31%→39%→43%) and Q1 2026 Brazil items sold grew +56%, implying consolidated Q1 growth plausibly near the required ~50% pace, which is why Kalshi has re-rated from 7% to 24%. However, the company has never posted a quarter above ~45% consolidated growth, margin compression and the EPS miss may limit how aggressively MELI subsidizes volume, and Q2-Q4 must hold near record growth rates with no company unit guidance to lean on. I anchor near the Kalshi 24% price with a slight tilt up for the strong Brazil datapoint, landing at 25% Yes.

No	78%

FY2025 items sold were ~2.4B (492M+550M+635M+~751M), so 3.6B requires ~50% full-year growth in 2026, above the peak observed quarterly rate of 43% in Q4'25. The trend is accelerating (28%→31%→39%→43%) and Brazil, MELI's largest segment, posted +56% items sold in Q1 2026, which makes ~50% consolidated growth for early 2026 plausible, but sustaining that pace through Q3-Q4 against much tougher comps (the free-shipping-threshold-driven acceleration laps in H2) and amid margin pressure that drew a 12% stock drop is a stretch. The Kalshi anchor of 24% (up from 7%) already reflects the strong Brazil print; I stay near it, shading slightly lower given the naive-trend model puts this deep in the tail and no consolidated 2026 unit figure confirms company-wide acceleration to the required level.

The Kalshi YES price is 24%, but exceeding 3.6B would require roughly 50-57% growth from the estimated 2.3-2.4B FY2025 base. Although quarterly growth accelerated through 2025 and Brazil posted 56% growth in Q1 2026, that result covers only one segment and does not establish company-wide growth at the required rate. The target exceeds the fastest recent consolidated quarterly pace of about 43%, while the Q1 EPS miss and margin compression add execution risk. I therefore move modestly below the market anchor while retaining meaningful upside probability for continued acceleration.

Yes	21%
No	79%

The 24% Kalshi YES price is the primary anchor, reflecting sharply improved sentiment after Brazil’s Q1 2026 items sold grew 56% YoY. However, reaching 3.6B requires roughly 50–57% full-year growth from the estimated 2.3–2.4B 2025 base, above every recent consolidated quarterly growth rate despite 2025’s acceleration from 28% to 43%. The Brazil result makes the threshold plausible, but no consolidated Q1 unit figure confirms that other markets matched it, while tougher second-half comparisons and margin compression create downside risk. I therefore move modestly below the market anchor, while assigning materially more upside probability than the naive historical model’s sub-1% estimate.

Q1 2026 Brazil items sold +56% suggests consolidated growth near 45-50% is plausible, and a back-of-envelope path (~740M/825M/940M/1.09B) lands right around 3.55-3.6B, making this a genuine coin-flip-adjacent threshold rather than the <1% tail a naive 25%-growth model implies.
