Kalshi just crossed its first international border — not through regulatory conquest but through a franchise model. XP Inc supplies 4.8 million clients and local compliance. Kalshi supplies the technology. The same pattern that globalized payment rails, exchanges, and SaaS is now globalizing prediction markets.
On March 9, Bloomberg reported that Kalshi has partnered with XP Inc. — Brazil's largest independent broker-dealer — to offer event contracts to Brazilian investors. It is Kalshi's first expansion outside the United States. The contracts cover Brazilian economic outcomes: inflation and interest rates. XP handles local distribution, client relationships, and regulatory compliance through its US brokerage arm. Kalshi supplies the trading technology and market design.
Kalshi co-founder Luana Lopes Lara described the logic: "It makes sense for us to go through these international partners. They already have the customers and the brand."
The sentence contains the entire thesis. Not we will build a Brazilian prediction market. Not we will navigate Brazilian regulation. We will go through partners who already have what we don't — local trust, local compliance, local distribution — and supply what they don't have: a new category of financial instrument.
The Model
The franchise model is not new. It is the dominant pattern by which financial infrastructure crosses borders.
Visa does not operate in two hundred countries because it built two hundred subsidiaries. It licensed its network to local issuers who handled regulatory compliance, customer acquisition, and merchant relationships. Visa supplied the rails. The local partners supplied everything else. CME Globex did not build trading floors in Tokyo, London, and Singapore. It provided electronic matching technology. Local exchanges connected their participants. SWIFT does not employ bankers in eleven thousand institutions across two hundred countries. It provides a messaging standard. Each institution implements it within its own regulatory framework.
The pattern has three invariant features. First, the technology provider supplies the instrument — the product design, the matching engine, the risk model, the settlement logic. Second, the local partner supplies the access — client relationships, regulatory standing, distribution infrastructure. Third, the regulatory navigation happens at the local level, within the local partner's existing framework, rather than through the technology provider obtaining a new license in every jurisdiction.
Kalshi and XP are executing this pattern precisely. Lucas Rabechini, XP's head of financial products, noted that the contract payoff structures "resemble derivative products familiar to XP's existing client base." The framing is deliberate. Event contracts are not being introduced to Brazil as a new category. They are being introduced as a variation on an existing one — derivatives that XP's 4.8 million active clients already understand and already trade.
The Classification
The regulatory signal from Brazil is as significant as the commercial deal.
Brazil's CVM — the equivalent of the SEC — authorized B3, the country's stock exchange, to introduce a new class of event-based derivatives in Q1 2026. The products are binary options on economic underlyings: the US dollar exchange rate, the Ibovespa index, bitcoin. Will the dollar fall below five reais on a specific date? Will the Ibovespa surpass a threshold in May? Future plans include GDP and IPCA inflation index contracts.
The classification is critical. CVM framed these products as derivatives — financial instruments regulated under securities law — not as gambling regulated under gaming law. B3 characterized the decision explicitly: "The world of derivatives is increasingly approaching the frontier of the predictive market." The statement positions prediction markets as an evolution of existing financial infrastructure, not an invasion from an adjacent industry.
This is the same classification battle that played out in the United States, but with the opposite trajectory. In the US, the path ran through courtrooms. Tennessee called event contracts swaps. Massachusetts called them bets. The CFTC spent years oscillating between prohibition and governance. The classification was contested, litigated, and resolved piecemeal over half a decade.
In Brazil, the classification arrived before the litigation. CVM made the determination as a regulatory act, not a judicial one. By the time the products reach Brazilian retail investors, they will already be categorized — derivatives, regulated by the securities authority, integrated into the existing financial framework. The regulatory question that consumed years of American bandwidth was resolved in Brazil before the first contract traded.
There is an access restriction that reveals how seriously the classification is taken. B3's initial event-based derivatives are limited to professional investors with financial assets exceeding ten million reais — roughly $1.9 million. This is not a consumer gambling product with guardrails. It is a sophisticated financial instrument with accreditation requirements. The restriction will likely loosen — B3 has indicated it will seek approval for retail access — but the starting point defines the category. In the United States, Kalshi launched retail-first. In Brazil, the same instrument class launches institutional-first. The product is the same. The onramp is different. Both converge on the same destination: prediction markets as standard financial infrastructure.
The Simultaneity
What makes the Brazil expansion structurally significant is not the deal itself. It is the timing relative to every other axis of expansion.
In the twelve months preceding this partnership, prediction markets expanded along four axes simultaneously. Each was covered in this series as it occurred. Together, they describe a category that is no longer experimenting with acceptance — it is scaling across every dimension that financial infrastructure scales across.
Institutional integration. Tradeweb made a minority investment in Kalshi and will pipe prediction market probabilities into its rates and credit marketplaces — the same terminals that institutional bond traders use daily. The New Plumbing documented this as the moment prediction markets entered the institutional data stack. Coinbase announced prediction markets powered by Kalshi. CNBC signed a multiyear deal to display Kalshi probabilities in on-screen graphics.
Regulatory normalization. The CFTC withdrew its proposed ban on political and sports event contracts. Chairman Michael Selig outlined a four-part regulatory agenda to "support the responsible development of event contract markets." On March 9 — the same day as the XP announcement — the CFTC submitted an advanced notice of rulemaking to the Office of Management and Budget. The Withdrawal documented the pivot from prohibition to governance. The rulemaking submission is the next step: from governance posture to governance framework.
Traditional exchange entry. Nasdaq filed with the SEC to list binary options on the Nasdaq-100. Cboe filed to reintroduce binary options, targeting a second-quarter launch. CME hit one hundred million event contracts traded in just eight weeks. Eurex is weighing entry. The Other Door documented the first filings. The subsequent filings confirm the pattern: every major exchange operator now has a prediction market strategy.
Asset class expansion. Kalshi partnered with Bezel, a luxury watch marketplace, to launch watch futures — event contracts on whether specific Rolex and Patek Philippe models will exceed price thresholds. The NHL signed an official data and IP licensing deal. A sports hedging startup, Game Point, partnered with Kalshi to let professional sports teams hedge performance bonus payouts via event contracts — framing the product as an institutional alternative to OTC reinsurance.
Four axes. Geography, institutional adoption, regulatory acceptance, asset class breadth. Each is expanding simultaneously. Each reinforces the others. Institutional integration makes regulatory normalization easier because regulators can point to institutional demand. Regulatory normalization makes international expansion possible because foreign regulators can reference the US framework. International expansion proves the instrument is not a local anomaly. Asset class expansion proves it is not a single-use product.
The Revenue
The commercial trajectory contextualizes the expansion.
Kalshi generated $263.5 million in fee revenue in 2025 — up from roughly $24 million in 2024. A 994 percent increase in a single year. Eighty-nine percent came from sports contracts. Total trading volume reached $22.88 billion. The Super Bowl alone produced $871 million in volume in a single day.
Robinhood, which sources order flow from Kalshi, reported prediction markets as its fastest-growing product line — nine billion contracts traded by over one million customers in its first year. In January 2026, Robinhood and Susquehanna acquired ninety percent of MIAXdx, a CFTC-licensed exchange, to operate their own prediction market infrastructure. The distribution partner became a competitor — the clearest signal that the category has crossed the threshold from novel to essential.
XP's client base adds a specific dimension to the growth arithmetic. XP has 4.8 million active clients and manages R$1.5 trillion — approximately $290 billion — in client assets. Brazil's B3 exchange has roughly four million individual investors with positions in custody. Brazilian retail investors have been reducing direct equity holdings — down twenty-three percent in 2025 — while increasing fixed-income exposure, a rational response to a fifteen percent benchmark interest rate.
Event contracts on Brazilian inflation and interest rates are not competing with equity trading in this environment. They are complementing fixed-income positioning. A Brazilian retail investor already expressing macro views through Selic-linked bonds can now express the same views through event contracts with binary payoffs and defined risk. The addressable market is not new retail investors. It is existing fixed-income investors adding a new instrument to an existing macro toolkit.
The Pattern
The United States has exported financial infrastructure before.
Treasury bonds became the global risk-free rate. The dollar became the reserve currency. Equity markets became the template — listing requirements, disclosure standards, market microstructure all followed American patterns into dozens of jurisdictions. Derivatives followed: options, futures, and swaps standardized in Chicago and New York spread globally through licensing agreements and protocol adoption. Payment networks followed: Visa, Mastercard, American Express exported their rails through local bank partnerships. Crypto followed: Bitcoin, created in the US ecosystem, traded globally within years.
Each export reshaped global finance. Not because the US forced adoption, but because the instrument solved a problem that local markets recognized once the solution existed. Treasury bonds did not need to be imposed on foreign central banks. They were the safest store of value available. Visa did not need to be imposed on foreign banks. It was the most efficient payment network available. Each instrument crossed borders the same way: through local partners who supplied access while the American originator supplied the standard.
Prediction markets are following the same path. The instrument — event contracts with binary payoffs, centrally cleared, regulated as derivatives — was designed in the United States. The regulatory framework was established through American litigation and agency action. The technology was built by American companies. The international expansion is happening through local partnerships, not subsidiary creation.
The difference between an experiment and infrastructure is exportability. An experiment works in one jurisdiction, under one regulatory framework, for one population. Infrastructure works everywhere, adapted to local conditions, through local partners. The Visa network is infrastructure. A pilot program is an experiment. The distinction is not about scale. It is about whether the instrument can survive translation — different regulations, different languages, different market structures, different investor populations — and still function.
Kalshi's event contracts on Brazilian inflation, traded through XP's distribution network, regulated as derivatives by CVM, settled through existing US clearing infrastructure, are the first test of that translation. If the contracts find liquidity — if Brazilian retail investors express macro views through binary payoffs the way American retail investors express political views through them — the instrument has survived its first translation. And an instrument that survives translation is no longer an experiment.
This series has tracked prediction markets through thirteen entries — their epistemic power, legal fragility, institutional integration, moral limits, regulatory pivots, counterparty risks, and the organized opposition they generate. The Export adds the dimension that none of the others could: geographic proof.
A prediction market that exists only in the United States, no matter how large, is a domestic financial product. Thirteen entries documented its growth within that boundary. The fourteenth documents the moment it crossed the boundary — not through regulatory conquest, but through the oldest mechanism of financial globalization: a technology provider and a local partner, each supplying what the other lacks.
The question this series began with — will prediction markets become a standard financial instrument or remain niche? — now has its first international data point. Brazil's CVM classified them as derivatives. XP is distributing them to 4.8 million clients. The CFTC is writing its first formal rules. Nasdaq and Cboe are filing their own versions. Tradeweb is piping probabilities into Bloomberg terminals. Robinhood built its own exchange to operate them.
Every major financial innovation — bonds, equities, derivatives, payment networks, digital assets — followed the same arc. Domestic invention. Regulatory contestation. Institutional adoption. International expansion through local partners. The contestation phase is ending. The expansion phase has begun.
