Longbridge, the brokerage powered by artificial intelligence (AI), is scaling up its presence in Singapore with a bold mix of 0 fee trading, advanced fintech infrastructure and advanced-grade tools made accessible to retail investors. The brokerage, founded in 2019, has seen rapid regional traction. Its latest campaign — "0 Fees for US, HK, and SG Stocks*" — positions it as the only brokerage in Singapore currently offering lifetime 0 commission trading across the three major global markets.
Xu Shengyu, CEO of Longbridge Securities Singapore, says: "Singapore's vibrant and dynamic market, Longbridge, is bringing an AI-driven trading experience to local investors through advanced fintech innovation. Our '0 Fees for US, HK and SG Stocks*' promotion reflects our commitment to lowering entry barriers and delivering better investing services."
The campaign builds on Longbridge's earlier lifetime 0 commission policy for the United States and Hong Kong markets. With the latest expansion in May, the same benefits have been extended to Singapore-listed stocks. New Singapore-based clients who meet the promotion criteria will enjoy waived commissions and platform fees across US, Hong Kong and Singapore. The initiative targets new users in a highly competitive market dominated by traditional bank brokerages and emerging fintech players.
Technological backbone
A core differentiator for Longbridge is its proprietary, cloud-native trading infrastructure. Unlike legacy platforms that rely on traditional data centres, Longbridge has built its system from scratch on public cloud architecture, integrating proprietary middleware for fast iteration and scalable performance.
“Our cloud-native system, built on public cloud infrastructure and proprietary middleware, offers high performance, scalability, cost-efficiency and high availability,” Xu explained. “The system is regarded as highly advanced within the industry.”
The platform delivers execution speeds of 6 milliseconds, supports microsecond-level market data refresh rates, and scales dynamically in response to trading volume surges. Longbridge has invested over $250 million to develop this infrastructure.
This technological edge supports improved superior uptime and responsiveness, particularly under high-load scenarios, a pain point for several incumbent platforms that have experienced outages of 10 hours or more.
What sets Longbridge apart is its infrastructure and how it leverages AI to democratise investing. Its flagship AI assistant, PortAI, is a real-time, finance-specific tool based on large language models (LLMs). It enables investors to access detailed stock insights, news summaries, advanced-grade analysis and automated trading assistance.
“PortAI was introduced on the Longbridge app as early as April 2023, making us the leading broker in the industry to release an AI assistant,” says Xu. “PortAI leverages tools inspired by advanced methodologies to support retail investors, helping them interpret market developments, such as earnings reports and industry chain data, and providing in-depth data analysis.”
PortAI supports real-time data across 35,000 stocks, 500 indices and 77 industries via chatbot and summary modes within the app. Based on internal system records, PortAI has been accessed over one million times globally in 2024. Integration with LLMs from OpenAI and DeepSeek enabled the tool to evolve into a multi-function assistant capable of summarising financial documents, responding to market queries and executing trades via LongPort’s Model Context Protocol (MCP).
“By generating market analyses and integrating with APIs, the intelligent assistant enhances decision-making efficiency and helps simplify the investment process,” says Xu. “Users can query their portfolio holdings, profit and loss status or historical trades simply through natural language.”
For developers and quantitative traders, Longbridge also offers LLM Text, a tool that uses natural language prompts to generate trading strategy scripts. “With this upgrade, professional developers can now integrate the full set of LongPort OpenAPI documentation into AI coding environments,” Xu adds.
Seamless experience across markets
Longbridge’s single multi-currency account offers access to more than 32,000 instruments globally, including stocks, ETFs, options, REITs, CBBCs and mutual funds. The platform supports trading in the United States, Hong Kong and Singapore markets, with added features like 24-hour US Overnight Trading and fractional share capabilities.
In 2024, Longbridge introduced over 120 new product features and rolled out 17 major app updates. New capabilities included Chart Trading, which allows users to place orders directly on chart interfaces, and Grid Trading, an automated strategy that lets users buy low and sell high within a predefined price range.
“Our proprietary Longbridge Pro desktop platform provides high-performance charting with dozens of technical indicators and drawing tools,” says Xu. “Chart Trading enables them to quickly respond to market volatility and capitalise on opportunities.”
The firm has also invested in risk management capabilities, especially for US options traders. Longbridge’s system supports advanced 0DTE (zero days to expiry) strategies, making it a preferred platform for options-savvy investors.
Trust remains a priority for Longbridge, which differentiates itself further by offering proactive user protection. In 2024, when an NYSE technical glitch caused erratic Berkshire Hathaway Inc Class A share movements, Longbridge generously offered support to affected clients by offering a compensation.
“At the heart of our strategy is a shared understanding across the Longbridge team: Always stand with our users,” Xu said. “This drives us to focus relentlessly on improving the user experience and ensuring investor needs are fully met.”
In another instance, Longbridge responded to a service outage from an external trading provider by intervening directly to validate and honour pending user trades — an uncommon move in the sector. This was a one-off, discretionary action based on the specific circumstances, and may not apply in all future cases.
Such initiatives have helped the firm secure over US$150 million ($192.74 million) in strategic investment from global financial institutions. It holds licences from regulators, including the MAS in Singapore, the SEC and FINRA in the US, and the SFC in Hong Kong.
Market outlook
According to the firm's data, Longbridge recorded a threefold growth in user asset scale and doubled its global user base in the past year. Order volume surged nearly 10-fold y-o-y, reaching 11.55 million in 2024. According to data from TradeGo, Longbridge in Hong Kong climbed from outside the top 500 to 32nd in broker rankings within three years, positioning it as the fastest-growing fintech brokerage in the city.
Singapore remains a key growth market. “We aim to deliver a seamless trading experience to more users in Singapore through our innovative products,” Xu says. “As investing becomes an integral part of daily life for more people, we hope every interaction with Longbridge serves as a meaningful exchange between investment and life.”
Future development plans include expanding PortAI’s predictive analytics capabilities, enhancing localisation for Singapore-based users, and exploring new market offerings. Xu notes that Longbridge will continue to prioritise user-centric innovation and technological excellence.
“Whether through continuous product innovation or our lifetime 0 commission policy, Longbridge's goal is to lower the barrier to entry for investing — enabling more people to participate in the markets,” he adds.
