Arkham Brings Whale Signal to Futu and Moomoo Trading Apps

By Marcus Bennett

Arkham has partnered with FUTU Holdings to bring on-chain whale tracking and institutional flow data directly into the Futu and moomoo trading apps, under the branded feature Whale Signal. The partnership was announced on November 13, 2026, and targets the retail traders who already buy and sell crypto on those platforms.

The deal puts a specialized crypto-intelligence product inside two of the most widely used retail brokerage apps. That is the core of it. Arkham, known for its blockchain analytics work, is now reaching investors who may never have used a dedicated on-chain tool before.

What does Whale Signal actually do?

The feature lets users follow three kinds of data: whale movements, institutional capital flows, and real-time exchange activity.

Each category answers a different question for a trader.

• Whale movements. Whales, in crypto shorthand, are wallets holding large amounts of a given asset. When they move funds, other traders tend to pay attention.
• Institutional capital flows. These track where bigger, professional money is going.
• Exchange activity. This covers deposits and withdrawals on trading venues — a signal many traders watch for hints of incoming buying or selling.

Arkham says the integration will deliver institutional-grade crypto intelligence to retail investors. The service will likely draw on the company's entity-labeling and monitoring capabilities. That is the part of Arkham's work that attaches real-world names to otherwise anonymous blockchain addresses, turning raw ledger activity into something a retail user can actually read.

So what does this change for the average moomoo user? In practice, it compresses the distance between on-chain data and the trade ticket. Signals that once required a separate analytics platform now sit next to the buy and sell buttons.

Where it will be available

Whale Signal is set to roll out in markets where Futu and moomoo already support crypto trading. Those are primarily the US, Hong Kong, and Singapore.

Futu, also known as Futubull, and moomoo are FUTU Holdings' two trading platforms. The company has been expanding its product lineup, with a particular push into crypto and AI features. This partnership extends that push by adding a data layer rather than another asset to trade.

The three-market footprint matters. It means the feature lands in jurisdictions where the brokerage already cleared the regulatory hurdles for crypto trading, rather than requiring new licensing of its own.

What the announcement leaves out

Neither company disclosed financial terms or revenue-sharing details for the arrangement. The announcement also did not include any new token launch — a notable omission in a sector where partnership news often arrives paired with token mechanics.

That restraint fits the product's positioning. Whale Signal is a data feature, not a market event. Its value depends on execution: how cleanly Arkham's labeling and monitoring pipeline plugs into two brokerage interfaces built for mainstream users.

Why brokerages want on-chain data

The larger story here is distribution. On-chain analytics has mostly lived in tools used by traders, researchers, and institutions. Packaging whale tracking and flow data inside a retail brokerage changes the audience for that information by an order of magnitude.

For Arkham, the deal puts its entity-labeling work in front of Futu and moomoo's user base. For FUTU Holdings, it differentiates two platforms competing on features in a crowded retail-trading market, and it deepens the crypto offering without adding regulatory exposure from listing anything new.

The rollout across the US, Hong Kong, and Singapore will be the test. If adoption holds, expect brokerage apps to treat on-chain intelligence as a standard feature rather than a differentiator.
