MercadoLibre (NASDAQ:MELI) posted a quarter that looks like two different companies stapled together. In its fiscal second quarter of 2026, net revenue and financial income jumped 50% to $10,169 million. Income from operations fell 17% to $683 million. Management described the profit squeeze as a deliberate choice to plow operating leverage back into its value proposition.
MercadoLibre is the region’s best-known online marketplace, plus a lot more. It earns commissions and shipping fees on goods sold, sells ads to merchants, and runs Mercado Pago, a fintech arm that processes payments, holds deposits, and lends money. Brazil, Mexico, and Argentina are its biggest markets.
So the real question is whether investors are watching a company invest in a wider moat, or one that has to pay more just to keep growing. The answer depends on what that spending is actually buying, a dynamic long-term investors weigh when eyeing transformative secular plays like the 10 Stocks That Will Change the World by 2030.
An Ecosystem That Feeds Itself
MercadoLibre’s edge isn’t any single business. It’s how the pieces push customers into one another. Shoppers who pay with Mercado Pago become borrowers, borrowers come back to shop, and sellers follow the traffic. The user numbers show that loop working. Unique active buyers reached 89 million in the second quarter, up from 71 million a year earlier. Fintech monthly active users climbed to 88 million from 68 million.
Advertising is the newest layer. Ad revenue grew 62% on an FX-neutral basis (stripping out currency swings), and the company says Mercado Ads topped a 10% share of Latin America’s digital ad market for the first time. Selling space to merchants who already depend on the platform is the same retail-media logic behind Amazon’s advertising business.
Cheaper Shipping, More Orders
The biggest bet is in Brazil. MercadoLibre lowered its free-shipping threshold there last year, and the payoff is visible in volume. Brazilian items sold rose 56% year over year in the second quarter, while gross merchandise volume (the total value of goods sold) grew 39% FX-neutral.
Company-wide, items sold hit 795 million, up from 550 million. The catch is cost. Higher shipping expenses weren’t fully offset by revenue, which squeezed gross margin. Still, the company says free and slow shipments are now contribution-positive across half of the R$19 to R$79 price range, a sign the cheaper orders are starting to pay their own way.
Lending is the other engine. The credit portfolio passed $16 billion, up 75%, and 2.6 million new credit cards went out during the quarter.

NIMAL (net interest margin after losses) slipped to 20.7% from 23.0% a year ago, but improved 3 percentage points from the prior quarter.
Is MercadoLibre Paying Too Much for Growth?
The skeptic’s case is easy to build. Net income fell 11% to $466 million, and diluted earnings per share dropped to $9.19 from $10.31. Operating margin sat at just 6.7%.
Cash is tighter, too. Adjusted free cash flow came to $214 million after $441 million of capital spending and $2.1 billion poured into the credit book. Net debt rose to $6,425 million from $4,682 million at the end of last year, and last month the company sold $1 billion of 5.850% senior notes due 2036.
That’s a real cost for a growth story. But it’s a funded one: much of the cash is going into loans that earn interest, not into losses.
Cheap Against Its Own Past
MercadoLibre trades at 49.20 times forward earnings, as of October 9. That looks steep next to the sector average of 14.78, and nobody would call it a bargain on that comparison. History tells a different story. The stock’s 5-year average P/E is 91.21, so investors are paying far less for each dollar of expected profit than they typically have.
The forward view hinges on growth. Analysts expect EPS to grow 46.20% in 2027. If that happens, today’s GAAP earnings dip looks like a trough, not a new normal, and the forward multiple starts to look more reasonable. A premium like this is typical of 10 Best Growth Stocks to Buy Now According to Billionaires, but it leaves little room if margins stay pinned near current levels.
Sentiment backs the patient view. Hedge fund interest ticked up, with 107 funds holding the stock in the most recent quarter, up from 102 in the prior one. Short interest sits at 1.63% of the float, suggesting relatively limited bearish positioning.
What Has to Go Right
The evidence suggests MercadoLibre is buying scale, not covering up weakness. Buyers, fintech users, items sold, and ad share are all growing fast, and the stock trades well below its usual multiple.
That makes the setup better suited to long-term growth investors who can stomach a few more quarters of thin margins. If you need steady earnings now, this isn’t that story. What would change the picture is credit: a sustained rise in delinquencies, or NIMAL sliding back while debt keeps climbing, would turn a smart investment into an expensive one.
