Kalshi and Alpaca announced a partnership on August 31, 2026, that would put Kalshi event contracts into Alpaca’s brokerage infrastructure for financial apps and institutions. The deal uses Alpaca’s API distribution model and Alpaca Derivatives LLC’s futures commission merchant registration, while Kalshi supplies the exchange, contracts and clearing.
What did Kalshi and Alpaca announce?
The companies said Alpaca will support access to CFTC-regulated event contracts through its brokerage infrastructure, powered by Kalshi. The announcement matters because it moves prediction markets further into the same API channels that fintech apps already use for stocks, options, fixed income and crypto, rather than treating event contracts as a standalone destination.
Alpaca framed the arrangement as a product expansion for its partners and builders. Kalshi framed it as distribution: Max Crowley, Kalshi’s vice president of business development, said in Alpaca’s announcement that the partnership expands access to Kalshi markets in the United States and abroad. That is a commercial claim from one of the parties to the deal, not evidence by itself that overseas launches are imminent.
The announcement identifies several functions in the proposed stack. Alpaca will support custody, money movement, statements and account management. Kalshi will provide the regulated marketplace, listed event contracts and clearing services. Alpaca said builders will be able to use existing order, position, activity and market-data interfaces extended for event contracts.
The important regulatory detail is narrower than saying Alpaca itself is a CFTC-registered firm. Alpaca’s August 17, 2026, announcement said Alpaca Derivatives LLC, an Alpaca subsidiary, registered with the Commodity Futures Trading Commission as a futures commission merchant and became a member of the National Futures Association. Alpaca’s August 31 disclosure lists Alpaca Derivatives LLC’s NFA ID as 0576042.
Is Alpaca Derivatives already operating as an FCM?
No. Alpaca’s own disclosure says Alpaca Derivatives LLC has not yet commenced regulated business operations as a futures commission merchant. That distinction makes the partnership an infrastructure and distribution announcement, not proof that Alpaca-powered event-contract trading is already live across its partner base.
An FCM typically handles customer-facing futures intermediation functions, including customer funds and account records. In this arrangement, Alpaca said Alpaca Derivatives would handle custody, money movement, statements and account management for event contracts, while Kalshi would remain the regulated marketplace and clearing provider.
For developers already using Alpaca’s Broker API, the pitch is operational simplicity: adding a new product category through familiar API workflows. The actual rollout still depends on Alpaca Derivatives beginning regulated FCM operations and on customers meeting eligibility, market-availability and jurisdictional requirements described in Alpaca’s disclosures.
That disclosure language is doing real work. Alpaca said availability depends on Kalshi’s listed markets, regulatory requirements and geographic eligibility, and added that the material is not an offer to open an account where Alpaca is not authorized to do business. For a cross-border brokerage infrastructure company, those limits are central to how much the announcement changes in the near term.
Why does Alpaca’s distribution network matter?
Alpaca has scale in brokerage infrastructure, but the numbers should be stated precisely. In its January 14, 2026, Series D announcement, Alpaca said it had partnered with over 300 organizations in more than 40 countries and supported millions of brokerage accounts at financial institutions and fintechs. It did not say every one of those organizations was a financial institution.
The same January announcement said Alpaca raised a $150 million Series D led by Drive Capital at a $1.15 billion valuation. Participants included Citadel Securities, Opera Tech Ventures, MUFG Innovation Partners, DRW Venture Capital, Kraken and other investors. Alpaca also said it secured a $40 million line of credit.
For Kalshi, Alpaca offers a business-to-business path into apps that may already have brokerage customers, compliance operations and market-data interfaces. That does not automatically convert Alpaca’s full partner list into Kalshi distribution. It does give Kalshi a way to pursue integration through infrastructure used by fintechs and institutions, rather than relying only on direct customer acquisition.
Alpaca’s own materials describe a multi-asset brokerage stack covering stocks, ETFs, options, crypto, fixed income and, through this partnership, event contracts. That positioning fits a broader industry pattern: prediction-market venues are trying to appear less like niche forecasting sites and more like regulated financial-market products that can sit beside other tradable instruments.
What can users trade through the integration?
Alpaca’s announcement described Kalshi event contracts tied to real-world outcomes, including elections, economic indicators and cultural events. It also said Kalshi markets trade around the clock and that payouts would be credited through Alpaca’s FCM stack after Kalshi settles resolved contracts.
Kalshi is a CFTC-regulated prediction market exchange in the United States, and its event contracts pay based on specified outcomes. The model is simple at the contract level: traders buy positions linked to whether a stated event occurs, and settlement follows the rules of the listed market. The complexity sits in regulation, distribution, customer eligibility and market integrity.
Alpaca’s announcement cited more than $40 billion in trading on Kalshi in July, according to Kalshi data. It also cited Bernstein estimates, reported by CNBC, that total prediction-market volume could reach $240 billion in 2026 and $1 trillion by 2030. Those figures are useful context, but the cited July number comes from Kalshi and the forward projections come from market estimates, not regulatory filings.
How does this fit with Kalshi’s international push?
Kalshi announced in June 2026 that it was expanding into Canada through Wealthsimple, the Toronto-based investing platform. The Alpaca partnership points in the same direction, but through an infrastructure provider rather than a single consumer investing app.
The cross-border angle is the most commercially ambitious part of the deal. Alpaca says it works with organizations in more than 40 countries, and Kalshi’s Crowley said the partnership is meant to expand access in the United States and around the world. Alpaca’s disclosure, however, says availability remains tied to listed markets, regulatory requirements and geographic eligibility.
That leaves the immediate milestone clear: the market should watch for the first live Alpaca-powered Kalshi deployment, not just the partnership announcement. Alpaca has not named the first partner app or first non-U.S. market expected to offer Kalshi contracts through the integration.
What is the competitive context?
Kalshi is not pursuing distribution in a quiet market. Polymarket has also moved toward a regulated U.S. structure: a CFTC industry filing identifies QCX LLC doing business as Polymarket US as a designated contract market, with designated status dated July 9, 2025. That makes any simple description of Polymarket as only an offshore, unregistered competitor incomplete.
Polymarket is also drawing large reported financing interest. Forbes reported on September 1, 2026, citing Bloomberg and other reports, that 1789 Capital, where Donald Trump Jr. is a partner, was leading a new Polymarket funding round at a $21 billion valuation, with Polymarket expected to raise $1 billion and 1789 Capital expected to invest about $300 million. Forbes described the financing as a reported new round, not a completed close.
For Kalshi, the Alpaca partnership is therefore less about announcing prediction markets as a category and more about proving distribution. The company already has direct brand recognition and a regulated U.S. exchange. The next question is whether event contracts can become a product that other financial apps embed, monitor and service at scale.
The next concrete milestone is operational: Alpaca Derivatives LLC beginning regulated FCM business and the companies naming the first Alpaca partner or market where Kalshi event contracts become available through the integration.
