Alpaca Raises $135M for Agent-First Brokerage Rails

Alpaca raised $135 million in equity led by Peak XV, the company announced Thursday morning, and paired it with roughly $300 million in debt from Payward (Kraken's parent) and BMO for a $435 million total package. The pitch is narrow and specific: Alpaca is not selling a trading app, it is selling the regulated plumbing that lets an AI agent place a real order in a real market. That is the bet, and the money says the plumbing is where the margin is.

• $135M equity led by Peak XV, with major participation from Elefund and returning backers Opera Tech Ventures (BNP Paribas Group's VC arm) and Unbound.
• No new valuation was disclosed. January's $150M Series D set the mark at $1.15 billion, and Alpaca chose not to print a fresh number six months later.
• Monthly active API users grew nearly 4x in six months, which Alpaca ties directly to its expanded agentic capabilities. Revenue has doubled year over year for three straight years.
• The debt is the tell. Roughly $300M in credit, mostly from a crypto exchange's parent company, is inventory financing for tokenized markets, not runway.

What did Alpaca actually announce?

Two things stacked into one press release. The equity piece is $135 million led by Peak XV, with Elefund taking a major position and existing investors Opera Tech Ventures and Unbound returning. The credit piece is the larger and stranger half: roughly $300 million in debt financing, primarily from Payward, the parent company of the Kraken exchange, alongside BMO. Add them together and Alpaca is announcing $435 million, which is the number the company leads with.

What Alpaca says it will do with it: accelerate "agent-first brokerage and API-first prime brokerage infrastructure." Strip the phrasing and it means letting institutions build products that reach across traditional equities and onchain markets through one integration, with AI agents as first-class callers rather than a bolted-on feature.

Why raise again just six months after a Series D?

January's Series D was $150 million led by Drive Capital at a $1.15 billion valuation. Coming back for $135 million in July is fast, and the absence of a new valuation number is the most informative thing in the release. Companies that repriced upward say so. Alpaca did not.

The charitable read, and the one the growth figures support, is that this is not a markup round at all. Alpaca reports monthly active API users up nearly 4x in six months and revenue doubling year over year for three consecutive years. It also spent the first half of 2026 buying regulatory surface: an IFSCA-regulated broker-dealer and payment service provider in GIFT City, India, plus UK and European regulated entities, completing passporting across all 30 EEA countries. Licences and acquisitions cost cash on a schedule that does not wait for a tidy valuation conversation.

What is the debt actually for?

This is the part most coverage will skim, and it is the most revealing. A $300 million credit facility is not how you fund engineers. Debt of that size, sitting at a company whose business is holding the underlying stocks that back tokenized equities, is balance-sheet capital. Alpaca says it has surpassed $1.5 billion in assets under custody for the real shares backing tokenized equities. Every tokenized share someone mints has to be collateralized by an actual share Alpaca holds, and buying those shares takes capital that equity investors price expensively and lenders price cheaply.

That the money comes primarily from Payward is the second signal. Kraken's parent is not a passive credit desk. It is a counterparty with a direct interest in tokenized equities existing at scale and clearing through infrastructure it has a relationship with. The financing and the commercial strategy are the same move.

What it means for the market

Alpaca is private, so there is no ticker to track directly, but the exposure is real and named. BMO (NYSE: BMO) and BNP Paribas (EPA: BNP), through Opera Tech Ventures, are both regulated banks putting capital into tokenized-equity infrastructure, which is a useful read on how large institutions are positioning rather than pontificating on the theme. Interactive Brokers (NASDAQ: IBKR) is the incumbent Alpaca has openly framed itself against, and the metric to watch is not Alpaca's headline raise but whether API-delivered brokerage volume starts showing up as pricing pressure.

The signal for investors is the missing valuation. A company growing API usage 4x in six months that declines to print a new number is either being disciplined about dilution or meeting a market that has cooled on fintech multiples since January. Both are plausible; the next round tells you which. For context on how this sits against the year's largest checks, see our Funding Tracker and the ranked Biggest AI Funding Rounds.

Who does this actually affect?

Three groups. Developers building agentic trading tools get a regulated venue that treats an agent as a legitimate caller instead of a terms-of-service violation, which is the genuine unlock here. Institutions get one integration spanning traditional and onchain markets, which is the whole reason Alpaca can charge infrastructure prices. And incumbent brokerages get a competitor whose distribution is other companies' products, which is a harder thing to out-market than a rival app.

The group this does not obviously help is retail. Alpaca sells to the companies that sell to you. A better agent-first backend shows up in your life as somebody else's feature.

Our take

The interesting thing here is not the $135 million, it is the shape of the package. Alpaca raised roughly twice as much debt as equity and did not reprice itself, which is the behavior of a company that needs a balance sheet rather than a headline. That is a more honest posture than most of what crosses the funding wire, and it fits the business: custodying real shares against tokenized ones is a capital problem before it is a software problem.

The "agent-first" framing deserves more skepticism than it will get today. Every brokerage API can claim agents call it, because agents can call anything with an HTTP endpoint. What would make the claim substantive is regulatory clarity on who is liable when an autonomous agent places a bad trade, and nobody, Alpaca included, has answered that. The 4x API growth is real and impressive. Whether it is agentic or just ordinary developer adoption riding a good narrative is precisely the number Alpaca chose not to break out.
