Kalshi partners with brokerage Alpaca as it tries to build its international audience. Published Mon, Aug 31 20268:00 AM EDT Listen 2min Key Points * Kalshi is looking to expand its international business through a partnership with brokerage and financial infrastructure startup Alpaca. * Alpaca, which reaches more than 14 million brokerage accounts globally, will now feature Kalshi's event contracts in its financial infrastructure. * The move will allow brokerages in countries around the world who use Alpaca's technology to connect to Kalshi's event contracts, after necessary local approvals are received. A supporter checks the gambling site 'Kalshi" just before State Assembly member, Alex Bores (D-NY) gives a speech to supporters at his watch party at The Freehand Hotel after conceding the congressional race to Micah Lasher who will replace Rep Jerry Nadler (D-NY) in NY's 12th Congressional District on June 23, 2026 in New York City. Prediction market platform Kalshi is working with brokerage and financial infrastructure startup Alpaca to bring its event contracts to an international audience. Individuals and businesses who use Alpaca's brokerage infrastructure will now have access to Kalshi's event contracts using the same technology utilized on the former's platform to trade other assets. It comes after Alpaca registered with the Commodity Futures Trading Commission to become a U.S.-licensed futures commission merchant, a brokerage that facilitates orders to buy or sell derivatives contracts, earlier this month. Alpaca moved forward with a move into prediction markets because it has seen demand from its users for access to event contracts, chief brokerage officer Tony Lee told CNBC in an interview. "Our mission is really to open up financial services to as many people around the world as possible, and you really have to go where the customer demand is," Lee said. That global potential is what made a partnership with Alpaca appealing to Kalshi, vice president of business development Max Crowley said. Alpaca has partnerships with more than 300 financial institutions and reaches 14 million brokerage accounts globally. As Kalshi seeks to go international, Crowley said having Alpaca's technology for brokerages in countries around the world to build on top of will make getting their prediction markets online in other markets happen faster, once local regulatory approval is received. "They're a trusted brand, they're technology forward, their customers love working with them," Crowley said. "It's going to take us a lot of time to build the business globally, but this technical partnership enables that." The partnership is Kalshi's latest move to go global. In June, it partnered with Canadian financial firm Wealthsimple to bring its markets north of the U.S. border. Alpaca also has 83,000 monthly users of its Application Programming Interface, which allows individual developers to build their own personal software for trading assets. CNBC has reported about the lengths individual prediction market traders go to gain an edge against other traders, many of whom have developed personalized automated software. Yoshi Yokokawa, co-founder and CEO of Alpaca, also acknowledged that it will take time for Kalshi's event contracts to scale internationally. But he said the potential crop of new traders that may come represents a major opportunity for prediction markets. "As that scales," Yokokawa said. "I think it should be pretty meaningful for event contracts as an asset class in general." Disclosure: CNBC and Kalshi have a commercial relationship that includes customer acquisition and a minority investment.
Alpaca launches Business Accounts for Broker partners. Alpaca is excited to announce that Business Accounts are now available for its broker partners through Alpaca's Broker API. Eligible partners can now onboard legal entities, including LLCs and S-Corps, and authorized signers through a structured, API-native workflow, designed to streamline onboarding and support business account trading. Why Alpaca is expanding Business Account support. Many broker-dealers are seeing increased demand for business account onboarding. However, onboarding business accounts has traditionally relied on manual document collection, fragmented compliance workflows, and support-intensive reviews that don't scale.[1] These operational challenges create friction for customers, increase costs for brokerages, and leave significant room for modern, automated onboarding solutions. Alpaca's Business Accounts streamlines the onboarding process through a fully structured, API-native workflow. Partners can now submit and manage multiple party types, including legal entities, and authorized signers, through the API, with KYB tied to the entity and KYC to each individual. The result is a single, automated workflow that supports programmatic onboarding of business accounts through a single workflow. The benefits of Broker API Business Accounts. Minimal integration. Its Business Account solution is built on the same Broker API infrastructure, so you can leverage the same integration, tech stack, and systems you already use and maintain. Automated onboarding and lifecycle management. Business onboarding is designed to support a streamlined workflow similar to individual account onboarding, with fewer manual document processes. Partners can submit required data through the API, submit verifications, and manage the full lifecycle from account opening through ongoing updates through a single integration. Business Account documentation and onboarding workflows will also be available through Alpaca's MCP Servers for Broker API, enabling engineering and operations teams to explore endpoints and test workflows without digging through documentation manually. Scalable by design. As partner volumes grow, Business Account workflows scale without requiring operations support for each account, meaning onboarding can be faster, continually updated, and managed programmatically at any volume. How Business Accounts work with Alpaca's Broker API. Alpaca uses a party-centric model, enabling entities to be submitted as a data object through the API with explicit fields for legal entity type, ownership percentages, UBO relationships, and authorized signer roles. The onboarding follows an API-first workflow: * Submit and update the legal entity and authorized signers as structured data * Post KYB for the legal entity and KYC for each individual through the API * Create the legal parties and then pass the legal entity party ID to the primary_account_holder_id, and per-account agreements with signer_party_id * Any changes to business and party records are managed through the same API, with key fields automatically triggering an account review flow Trade confirmations, monthly statements, and tax reporting forms are generated automatically in the legal entity's name, so partners do not need to build separate document handling workflows.For more information on its Business Trading Accounts, please read its Broker API Docs. What's next. Business Accounts are a critical step in Alpaca's product roadmap to support institutional trading. As Alpaca expand its support, Alpaca will continue to build out features and enhancements in collaboration with its partners. "The complexity of onboarding business accounts has been an ongoing barrier in the industry. Paperwork, compliance requirements, and manual systems created a real barrier between brokers and their users," said Hakan Bayraksan, Senior Director of Product at Alpaca. "We've engineered an API-first system that reflects how entities and compliance teams think about ownership and verification, so that our partners can expand their addressable market without rebuilding their stack. With this launch, we've removed a key structural barrier." Eligibility. Business Accounts are available to partners who have been approved for KYB and KYC reliance. Partners not yet approved will need to complete this approval process before enabling business account onboarding. Get started. For prospective partners, please reach out to Alpaca's Sales team at [email protected] or fill out the form below. For existing partners who are looking to integrate Business Accounts or would like to run KYB and KYC reliance, please contact your Customer Success Manager or email [email protected].

Gate follows Binance into US equities with 10,000 stocks and ETFs. Thursday, 13/08/2026 | 08:26 GMT-7 by Tareq Sikder * The firm expands into US equities with Alpaca's brokerage and custody infrastructure. * The company launches gStocks, tokenized US stocks, and explores AI tools for retail investors. Alpaca has partnered with cryptocurrency platform Gate to support its launch of US stocks and exchange-traded funds, initial public offering allocations and tokenized stocks. Gate's move follows a broader push by cryptocurrency exchanges into traditional equities. In June, Binance added 7,000 US stocks to its platform, with Alpaca providing custody, dividend processing and corporate-action support. The trend is giving retail investors and traders on crypto platforms access to a wider range of traditional market products. Alpaca supports Gate's US stock launch. Under the partnership, Gate users can access more than 10,000 US-listed stocks and ETFs through Gate Stocks. Eligible users can also request allocations in US IPOs. Alpaca provides the brokerage infrastructure for these products, including the brokerage functions needed to support trading in the underlying securities. The partnership also supports Gate's launch of gStocks, its tokenized US stock offering. Alpaca said its infrastructure handles the custody and settlement of the underlying shares. Yoshi Yokokawa, co-founder and CEO of Alpaca, said the company's infrastructure is designed to help "financial platforms expand into global markets." "We believe the future of investing lies in connecting digital assets and traditional finance," said @Han_Gate, Founder and CEO of Gate. "Alpaca's infrastructure helps Finance Magnates Ltd. broaden access to US markets, bring multiple asset classes together within the Gate ecosystem, and give its... - Alpaca (@AlpacaHQ) August 13, 2026 Gate develops AI tools for traders. Gate said the launch is part of its expansion beyond digital assets into traditional financial markets, wealth management, payments, Web3 and artificial intelligence. The partnership allows users to access stocks and cryptocurrencies through the same platform. Gate is also developing AI tools for retail investors, professional traders and developers to analyse markets and manage assets. Coinbase, MEXC Expand Beyond Digital Assets The move is part of a shift among crypto exchanges towards offering traditional financial products. Earlier this year, Coinbase outlined plans for a multi-asset platform covering cryptocurrencies, equities, derivatives and prediction markets. It described the model as an "Everything Exchange" operating across several asset classes. MEXC also entered the US stock market with RealStocks, giving users access to US-listed shares and dividends through a licensed brokerage partner.

Alpaca MCP Server: trading tools plus in-context API docs. Alpaca's Trading MCP Server 2.2.1 adds read-only documentation tools so agents can search Trading, Market Data, and Auth API references - operations, parameters, constraints, source links - without pasting docs into the prompt. Setup, verify prompts, and how this fits agent-first broker APIs. * Trading MCP Server now exposes read-only docs tools for Trading API, Market Data API, and Authentication. * Agents can map intent | operation | params/response/constraints + source links inside the same session as market/account/trading tools. * Docs tools do not place or modify orders - use them to review before acting. * Feature ships in v2.2.1; uvx users: alpaca-mcp-server@latest, restart client, new chat. * Pattern for any serious API MCP: tools from OpenAPI + retrieval over the human docs that OpenAPI omits. Broker and market-data APIs are a natural MCP surface: list positions, fetch bars, submit a paper order. The failure mode is familiar - the model has tools but not the manual: bracket vs simple order, replace constraints, options chain shape, auth headers. Builders paste half the docs into the system prompt or hope the model remembers. On 10 Aug 2026 Alpaca shipped documentation access on the same Trading MCP Server that already exposes market data, account, and trading tools. Announcement: Alpaca's MCP Server for Trading API Adds Documentation Access. What shipped. Read-only documentation tools covering: * Trading API * Market Data API * Authentication references Through those tools a connected assistant can search supported API references, pick an operation for a task, and inspect parameters, request shape, response fields, constraints, and source documentation links. They do not change accounts or order state. V2 already built most action tools from OpenAPI (operations, params, schemas). Docs tools add the surrounding intent layer OpenAPI usually lacks: what the operation is for, what can go wrong, what to check before calling it. Why it matters for agent builders. Before vs after | Before | After (docs tools) | | Paste docs into prompt or RAG yourself | Retrieve scoped API context on demand | | Tools without "which endpoint?" reasoning | Intent | documented operation | optional tool call | | Easy to invent fields | Review request against docs + source links | | Docs browse in a browser tab | Same MCP session as trading/data tools | This is the same pattern good Solana agent stacks want: executable tools + authoritative docs retrieval, not tools alone. Related DevRels threads: MCP + payments, Solana developer MCP, protocol "docs as tools." Example prompts alpaca highlights. * Bracket order: show operation, required params, request shape, response fields * Replace order: which operation, constraints, auth requirements * Review a draft order payload against docs; flag missing/unsupported fields; include source links * Option chain: only the docs needed for the operation and inputs * Explain behaviour and constraints without placing or modifying orders Operational habit: start sessions with "use documentation tools only" until the plan is solid, then allow trading tools (preferably paper keys first). Setup. New install. * Alpaca Trading API account + paper API keys * Connect per MCP server docs or alpacahq/alpaca-mcp-server * Restart the MCP client after config save * New chat | docs-only verify prompt (below) Existing V2 users. Documentation access requires Trading MCP Server 2.2.1+. With uvx: uvx alpaca-mcp-server@latest -version # expect 2.2.1 or newer # fully restart MCP client; open a NEW conversation V1 users should migrate to V2 first (see Alpaca's V1 | V2 notes). If docs tools missing: confirm version, full client restart, new conversation, then troubleshooting in their MCP docs. Verify prompt. Find the Alpaca API documentation for replacing an existing order. Return the operation, required parameters, constraints, response fields, and source links. Use documentation tools only. Design takeaway for your own MCP servers. * Generate mutative/read tools from OpenAPI (or IDL) so schemas stay true * Add read-only doc search over the human docs site (and link canonical URLs) * Separate tool classes so agents can be instructed "docs only" before "trade" * Default examples to paper / sandbox credentials * Never treat model output as compliance or investment advice - Alpaca's own disclaimer applies; same for any agent trading stack Ecosystem context. Alpaca is also pushing a Skills library for AI agents and a Trading API CLI. Docs-in-MCP is the glue between "agent can call APIs" and "agent knows which call is legal." This is equities/options brokerage infrastructure (Alpaca Securities / FINRA/SIPC), not a Solana program - still relevant to DevRels readers building agent toolchains, multi-agent trading demos, or MCP servers for their own APIs. Summary. Alpaca's Trading MCP Server 2.2.1 adds read-only API documentation tools alongside market data, account, and trading tools so agents can resolve intent to documented operations with parameters, constraints, and source links - without stuffing the prompt with manuals. Update with uvx alpaca-mcp-server@latest, restart the client, verify with a docs-only prompt, and keep order tools gated until review is done. For anyone shipping MCP on a real API: OpenAPI tools + docs retrieval is becoming table stakes. Get new articles in your inbox. Technical deep-dives on Solana tooling, infrastructure, and ecosystem. No noise.
PutHouse integrates with Alpaca's Trading API to automate options income strategies. PutHouse is an automated options platform that implements income strategies such as covered call and cash-secured put, managing the process from entry to exit without requiring manual order placement. Instead of manually screening contracts, calculating risk, and placing trades, PutHouse automates screening and trade execution strategy through Alpaca's Trading and Market API, so users can stay invested in stocks and potentially generate options income. Options involve substantial risk and are not suitable for all investors. Covered call and cash-secured put strategies can result in losses, including the loss of principal. Please read Characteristics and Risks of Standardized Options before investing in options. Automated options trading execution. Using Alpaca's APIs and predefined risk-management parameters, PutHouse handles execution automatically, helping investors generate options premium income without needing to manually trade every day. With a covered call strategy, investors can earn upfront income (the premium). In return, they agree to limit some of the stock's upside if the share price rises above the option's strike price. PutHouse evaluates predefined strategies and market inputs using either preset modes or user-defined criteria. The platform also provides AI-generated explanations as a supplemental tool, helping users understand why a trade was placed or skipped and the market context behind each decision. AI-generated outputs may be incomplete, inaccurate, or unavailable and should not be relied upon as the sole basis for any investment decision. Earn 3.30% APY on eligible uninvested cash. For uninvested cash, users may earn interest through Alpaca's High Yield Cash program*, which currently offers an APY of 3.30%. APY is current as of November 4, 2025, variable, and subject to change without notice. Eligibility requirements apply. Cash used to meet option requirements is not eligible for the program. FDIC insurance coverage is subject to applicable program terms and conditions. Systematic risk management. PutHouse leverages Alpaca's Trading API to automatically size trades, place orders, and evaluate factors such as volatility risk premium, relative strength index, and upcoming earnings and corporate events. These parameters are available through preset trading modes and may be customized to align with a user's investment objectives and risk preferences. Why alpaca is the underlying infrastructure. PutHouse chose Alpaca because automation requires more than a brokerage account. It requires reliable technology infrastructure, stocks and options data, and account permissions that support a fully automated experience. Alpaca provides the infrastructure to connect to user accounts, analyze market data and strategy parameters, and place trades programmatically. This allows PutHouse to focus on the user experience and simplify options trading for investors. Contact alpaca. Want to learn more about joining Alpaca's Connect Marketplace?
