Alpaca has rolled out US IPO access through its Broker API, giving broker partners a powerful new tool to let their clients participate in fresh American stock offerings. The feature expands on the platform’s existing support for trading shares immediately after they debut publicly, opening doors to early-stage investment chances that were long out of reach for most everyday investors.
The timing could hardly be better. With high-profile private firms such as SpaceX, OpenAI, and Anthropic widely expected to go public in the coming months, demand for IPO participation is rising fast.
For years, retail investors around the world have struggled to secure allocations in US initial public offerings, which underwriters traditionally reserved for large institutions and wealthy clients.
Alpaca’s new capability aims to tear down those barriers and help partners serve a broader audience.
Market momentum supports the move. According to recent data, the global IPO landscape rebounded strongly in 2025, with 1,331 deals raising a total of $177 billion—a 44 percent jump from the previous year.
In the United States alone, 216 companies listed, generating $47.4 billion in proceeds.
That represented a 23 percent increase in deal count and a 44 percent rise in capital raised compared with 2024. Sectors drawing the most excitement included artificial intelligence, cryptocurrency, digital assets, aerospace, and defense.
Partners who integrate the service stand to gain several clear advantages. First, offering IPO access sets them apart in a crowded market by giving retail users a chance to invest at the earliest public stage rather than waiting for secondary trading.
Second, major IPO events often spark broader interest in investing, helping brokers attract and retain new accounts.
Third, the added trading activity around new listings can boost order flow and long-term client engagement.
From a technical standpoint, Alpaca designed the experience to fit neatly into existing equity trading workflows.
Partners receive detailed deal information in advance, including company names, proposed tickers, prospectuses, price ranges, and expected listing dates. End users can then submit dollar-denominated conditional buy orders.
They retain the ability to adjust or cancel those orders right up until the day before the IPO; after that point, the orders become firm.
Once the offering closes, shares move through the Depository Trust & Clearing Corporation (DTCC) and are automatically journaled into customer accounts, appearing ready for trading when the market opens on IPO day.Integration is deliberately straightforward.
Orders are placed through the same familiar Broker API endpoint used for regular stock trades.
Real-time updates arrive via Server-Sent Events, and Alpaca supplies all necessary regulatory details without extra fees or complicated manual processes.
The result is a clean, unified experience that lets partners launch the feature quickly.
“As US IPO volumes return to levels not seen in years, global investors are showing they want more than just broad-market exposure—they want to participate from the very beginning of a company’s public journey,” said Hitoshi Harada, co-founder, chief product officer, and chief technology officer at Alpaca.
“We built this capability to meet that demand and give international investors a seat at the table from day one.”
Alpaca, a self-clearing US broker-dealer headquartered in the United States, powers brokerage infrastructure for fintechs and institutions in more than 40 countries.
The company currently supports over 10 million accounts and offers access to stocks, ETFs, options, fixed income, crypto, and additional embeddable finance tools. With this IPO launch, Alpaca continues to strengthen its position as a provider of brokerage technology.
