📋 Executive Summary

Seven long-term investors gathered to decide between MercadoLibre (MELI) and Nu Holdings (NU)—two Latin American giants blending commerce and finance. The question: Which compounds shareholder value more predictably through 2035?

  • 🏆 Winner: MercadoLibre (MELI) — 4 votes. Its dual marketplace-fintech model, consistent 16.6 % ROIC, and self-funded reinvestment make earnings more forecastable than any bank credit cycle.

  • 🥈 Runner-Up: Nu Holdings (NU) — 3 votes. Its 33 % ROE and explosive customer growth signal strong momentum, but leverage and macro sensitivity cloud long-term certainty.

  • ⚠️ Dividing risk: whether fintech lending growth can scale without destabilizing defaults.

  • 💡 Surprising insight: even Buffett conceded NU could mature into a “regional Visa,” though he still preferred MELI’s predictability.

  • 🔢 Most decisive metric: MELI’s sustained $8.6 B free cash flow, proving durability; NU’s shorter profit history demanded faith.

Bottom line: in emerging markets, longevity and self-funded growth outweigh speed. MercadoLibre’s flywheel turns quietly, reliably; Nu’s brilliance dazzles but depends on credit weather that no one can model a decade ahead.


PART 1: THE CONTENDERS

Buffett: “Both are incredible stories. MercadoLibre moves every parcel and payment across Latin America; Nu gives people banking they never had. One monetizes commerce, the other monetizes trust. Before we choose, let’s see the numbers.”

Metric NU Holdings (NU) MercadoLibre (MELI)
Current Price $15.19 $1 777.00
Market Cap $72.8 B $100.8 B
Revenue (TTM) $11.52 B $26.2 B
EPS (TTM) data not available $40.97
P/E Ratio 36.9× 48.5×
ROIC (TTM) data not available 16.6 %
ROIC (5 Y Avg) data not available data not available
Operating Margin data not available 12 %
Net Margin 17.1 % 7.9 %
ROE (TTM) 33 % 49 %
Free Cash Flow $2.07 B $8.61 B
Debt/Equity 0.45 data not available

Buffett: “There you have it: Nu smaller, faster, and more profitable on paper; MercadoLibre bigger, steadier, with proven cash generation. Which of those traits matters most ten years out?”


PART 2: BUSINESS QUALITY & MOATS

Munger: “Start with predictability. Banks die from tiny errors in credit quality; marketplaces die from competition. I’d rather battle rivals than credit contagion. Nu’s glamour hides fragility—every percentage point of default wipes out capital. MercadoLibre earns on what people already want to buy and ships what’s inevitable.”

Kantesaria: “True, Charlie, but MELI isn’t invincible; its fintech arm lends too. Yet its moat is geometric—commerce drives payments; payments feed commerce. Nu’s moat instead comes from cost and data: zero branches, precise behavioral lending. The deeper question is structural: can Nu’s data turn into a toll on regional transactions, like Visa’s?”

Tepper: “Dev, that toll only prints money if macro stays stable. Brazil and Argentina rarely oblige. Nu’s margin depends on rates below crisis levels. MELI’s marketplace cash flow hedges currency shocks because buyers and sellers transact locally. That self-hedge matters more than fintech spread income.”

Vinall: “David, let’s not dismiss youth’s advantage. Nu’s built 131 million customers in a decade—insane velocity. Switching banks in Latin America is paperwork hell. Commerce can switch platforms overnight; banking cannot. That friction is economic gravity, even if credit risk lurks.”

Pabrai: “Robert, friction helps survival but not necessarily returns. MELI’s at $100 billion market cap—hard to triple. Nu’s smaller pond means asymmetric upside if it executes. For me, asymmetry trumps moat size.”

Prasad: “But Mohnish, asymmetry counts only if survival is probable. Banking evolves faster than retail. Structures that demand constant reinvention die young. MELI’s ecosystem—physical goods plus payments—adapts naturally. Nu’s must reinvent credit continuously.”

Buffett: “Pulak, I agree. Commerce is habitual; lending is behavioral. MELI still relies on buying goods, a timeless act. Nu relies on human optimism about debt. I can project purchases further into the future than sentiment about borrowing.”


PART 3: FINANCIALS & TRACK RECORD

Munger: “The numbers confirm the intuition. MercadoLibre climbed from barely breaking even a decade ago to $26 billion revenue and $8.6 billion free cash flow today—proof of scalability. At its historical growth rate around 12 %, $40.97 EPS compounds to roughly $127 in ten years. Slap on a conservative fifteen-times multiple—call it a near-doubling without stretching imagination.”

Kantesaria: “Charlie, that’s steady math, though MELI’s real magic is reinvestment quality: 16.6 % ROIC. If they reinvest half of earnings, value compounds near eight percent plus growth—around mid-teens annually. Nu’s story is shorter but striking: 33 % ROE last year, net income from a loss of $364 million in 2022 to $1.97 billion in 2024. Let’s normalize that—assume 15 % growth for a decade and modest multiple; EPS could triple. Yet credit provisions can swing those profits violently.”

Vinall: “Let me extend MELI’s projection precisely. Starting $40.97 EPS, ten years at 12 % gets $127. If confidence returns and the market rewards stability with 25× earnings, we reach roughly $3 175 per share—1.8× return, about 6 % annual. If momentum holds at 15 %, EPS ≈ $165 and price ≈ $4 125—2.3× total, 8.7 % yearly. Reasonable upside without betting on miracles.”

Tepper: “Robert, you’re assuming capital stays patient. Latin volatility punishes optimism; 25× exit feels rich. Cut it to 15× and total return slips to 1.4×. The edge may come from timing—buying during political panic, not at stability.”

Pabrai: “Exactly. Nu fits the asymmetric template better. Price $15, say earnings triple by 2035. With a compressed 20× terminal multiple, we hit $36 — 2.4×. Add five years of compounding, roughly 3×. That’s my ‘heads I win, tails I don’t lose much.’ MercadoLibre can’t deliver that math; too big.”

Prasad: “But Mohnish, math without resilience is fantasy. Nu’s high ROE stems from leverage; MELI fuels growth through free cash flow. No oxygen from the outside. In biological terms, MELI photosynthesizes; Nu breathes borrowed air.”

Buffett: “And organisms that feed themselves survive longer. Nu’s EPS surge looks great—but one credit squeeze tells if it’s built on sand. MELI’s cash consistency reminds me of AmEx—a network funded by its own float and customer loyalty.”

Munger: “Second-order thinking, Warren: high banking returns invite competitors. As Nu grows, incumbents cut fees, digitalize fast, and returns normalize. Commerce has many rivals too, but MELI’s logistics web resists imitation. Competition erodes banks faster than delivery networks.”


PART 4: VALUATION & RETURN COMPARISON

Metric NU Holdings (NU) MercadoLibre (MELI)
Current Price $15.19 $1 777
Today’s EPS data not available $40.97
Growth Rate (10 Y) 15 % assumed 12 %
Projected EPS (10 Y) data not available (≈ 3× current net income) $127
Exit Multiple 20× 25×
Projected Price ≈ $36 $3 175
Total Return ≈ 2.4–3× 1.8×
Annualized Return ≈ 9–10 % 6 %
Implied Growth (from P/E) ~15 % ~17 %

Vinall: “At 48× earnings, the market assumes ~17 % annual EPS growth for MELI—above its 12 % history. Nu’s 36× implies ~15 % growth—closer to plausible. Expectations reflect optimism about MELI’s fintech margins expanding faster than reality.”

Munger: “Hence no margin of safety. Both priced for perfection. Waiting for dislocation beats paying up.”

Kantesaria: “True, but MELI’s quality justifies a partial premium. Even if growth slows, reinvestment at mid-teens ROIC keeps intrinsic value compounding. It’s the same logic that sustains Visa and MSCI at premium valuations.”

Tepper: “Valuation dances with sentiment. MELI’s down 10 % since research—a healthier entry level. If Latin credit conditions tighten and fear spikes, I’ll swing. Nu’s roughly unchanged; less reward waiting.”

Prasad: “Still, adaptability trumps sticker price. MELI’s integration—physical commerce and fintech—absorbs shocks better. Nu’s mono-line lending magnifies them. Investors get volatility either way; only one has structural ballast.”

Buffett: “So you pay 48× for visibility or 36× for velocity. For me, visibility wins. Inverting uncertainty, the slower business yields the more reliable return.”


PART 5: RISKS & SCENARIOS

Munger: “Imagine 2035—regulators crack down on fintech lending after defaults. Nu’s credit tap tightens; growth halts; valuation halves. First-order: profits vanish; second-order: depositor trust evaporates. That’s extinction pattern.”

Kantesaria: “The inverse could occur too—machine-learning underwriting slashes losses; fintech rivals collapse; Nu evolves into infrastructure layers like Visa. Then second-order effect—MELI’s merchant fees face pressure as Nu’s rails undercut them.”

Tepper: “Macro always interferes. Inflation spikes lift funding costs for both, but MELI’s commerce offsets currency by local pricing. Nu’s loan book concentrated in Brazil—systemic exposure. MELI earns cross-border diversification.”

Vinall: “Execution complexity risk: MELI’s logistics expansion may overshoot—if capex dilutes ROIC below 8 %, compounding engine stalls. That’s the thesis killer. They must grow soberly.”

Pabrai: “Currency collapse risk alone can halve U.S.-dollar returns. I want optionality to escape such exposure; smaller, nimble fintech fits that. Nu can pivot faster than MELI’s infrastructure-heavy model.”

Prasad: “Culture risk matters too. MELI’s founder Marcos Galperin has guided since 2000—continuity breeds discipline. Nu’s youth makes succession uncertainty real. Founder DNA often decides survivability through disruption.”

Buffett: “Then behavioral risk—consumer trust. Latin consumers forgive slow delivery; they don’t forgive data breaches. A single cybersecurity scandal can crater Nu faster than economic policy. Predictability comes from habit, not hype.”


PART 6: INVESTOR PICKS

🦅 Buffett’s Pick — MercadoLibre Inc (MELI): “I can sketch MELI’s 2035 earnings on paper with confidence: people buying goods, shipping parcels, paying digitally—inevitable behaviors. Nu’s profits depend on perpetual optimism about debt. A business that self-finances growth at 16 % ROIC and throws off $8 billion FCF resembles the Latin Amazon-plus-AmEx. At today’s price, not cheap but comprehensible; predictability trumps imagination.”

🦉 Munger’s Pick — MercadoLibre Inc (MELI): “Inversion decides. Banks face credit blowups; retailers face rivalry. Competition hurts less than insolvency. MELI survived regional chaos and still compounded cash flow. I’ll wait for cheaper entry, but if I must pick, I’ll choose the one that can’t vanish overnight.”

🎯 Kantesaria’s Pick — MercadoLibre Inc (MELI): “Reinvestment quality rules. The commerce-payments flywheel channels every retained dollar into 16 % returns, creating long-duration compounding. Nu’s results shine now but lack history. Patience with a proven toll bridge beats excitement over a nascent one.”

🦁 Tepper’s Pick — Nu Holdings Ltd (NU): “From a trading lens, Nu’s setup thrills me: smaller cap, rapid growth, investor skepticism ready to unwind. Any easing in rates could double the stock quickly. MELI’s steady compounding is admirable—but lacks asymmetry. I chase dislocations, not serenity, so Nu fits.”

📚 Vinall’s Pick — Nu Holdings Ltd (NU): “I see the compounding machine just starting. Thirty-three percent ROE, minimal capex—cash converts cleanly to profit. Even slowing to 20 % growth sustains 15 % CAGR returns. Founders here are disciplined; innovation widening the moat, not narrowing it. Nu’s phase of acceleration still ahead.”

🔥 Pabrai’s Pick — Nu Holdings Ltd (NU): “MercadoLibre’s $100 B size kills asymmetry. Nu’s $73 B cap offers room. If profits triple and multiple holds near 20×, price = $45 — 3× upside by 2035. Downside—profitable base limiting loss. Small, early, mathematically feasible; fits my ‘heads I win’ rule.”

🌿 Prasad’s Pick — MercadoLibre Inc (MELI): “Evolution favors adaptable species in slow-changing habitats. Commerce changes slowly; banking mutates fast. MELI integrates online and offline economies, thriving through turbulence. Founder continuity adds genetic stability. Quality first, price second—MELI wins the survival test.”


PART 7: THE VERDICT

Investor Pick Core Reason
Buffett MELI MercadoLibre’s commerce flows remain forecastable decades out, built on habits not credit cycles. Its 16.6 % ROIC and $8 B free cash flow prove self-financed durability. Nu’s dependence on borrower sentiment makes its future harder to model.
Munger MELI Applying inversion, avoiding stupidity means bypassing leveraged banks. Marketplace volatility beats credit fragility. MELI’s resilience through Latin chaos demonstrates a moat that withstands macro storms.
Kantesaria MELI Reinvestment quality and dual-platform structure make compounding almost mechanical. At mid-teens ROIC and expanding payments reach, MELI offers durable high-return reinvestment; Nu’s shorter record leaves uncertainty.
Tepper NU Smaller, faster-growing, sentiment-discounted fintech offers asymmetric trade. Rate easing or credit tailwinds can re-rate valuation sharply. MELI’s size limits upside; Nu’s reflexivity amplifies it.
Vinall NU Scaling from 131 million customers with 33 % ROE, Nu enjoys a long runway. Execution discipline and founder alignment sustain high reinvestment returns. Market-implied growth assumptions look attainable, delivering 15 % CAGR potential.
Pabrai NU At 36× and $73 B cap, Nu remains within asymmetric range—triple potential if profits sustain. MELI exceeds $100 B cap; impossible to triple. He favors the smaller, cheaper option with defined upside math.
Prasad MELI Evolutionary durability drives the pick. MELI’s slow-changing commerce base and founder stewardship ensure adaptability through volatility. Nu’s constant innovation requirement raises extinction risk; predictability wins.

Vote Count:

  • MercadoLibre (MELI): 4 votes

  • Nu Holdings (NU): 3 votes

🏆 Winner — MercadoLibre Inc (MELI) — 4 votes

🥈 Runner-Up — Nu Holdings Ltd (NU) — 3 votes

Buffett (concluding): “In fast-growing regions, investors chase speed. We prefer certainty. MercadoLibre earns a small toll on an inevitable activity—buying goods. Nu earns a spread on human optimism. Over decades, predictability compounds more safely than exuberance.”
