Unusual Whales started from a specific mission: exposing congressional insider trading. That origin shapes everything about the platform. What began as one person’s project to track how members of Congress trade stocks has expanded into a comprehensive options flow platform covering live options data for every transaction on every US ticker, dark pool and institutional data, real-time charting, unusual activity alerts, and one of the most detailed congressional trading trackers available to retail investors. The platform is run by a small team that has never taken outside funding. That independence is stated directly in the documentation and is part of how the platform presents itself.
Three paid tiers exist: Free Shamu (free), Buffet’s Buffet ($32/month or $384/annually), and Super Buffet ($42/month, with triannual and lifetime options available). The docs make clear that pricing information is subject to change and traders should verify the current pricing page before subscribing.
Credibility Check
Company: Unusual Whales (legal entity not publicly named in site documentation) Contact: support@unusualwhales.com (billing), dev@unusualwhales.com (API support) Address: Not disclosed on the website or in documentation Founded: 2020 (per documentation describing congressional tracking work) Trustpilot: Profile exists but has 0 reviews, unclaimed as of April 2026 Press: Referenced in documentation as covered by financial media; the congressional trading reports have received significant press attention
No physical address is disclosed anywhere in the public-facing site or documentation. The legal entity name does not appear in the documentation. No founder or team members are named publicly on the site, though the documentation describes the platform as having started from one person’s work on congressional trading data. The docs explicitly state the team has never taken outside funding and describe themselves as a small team building affordable tools for retail traders.
Unusual Whales has no Trustpilot reviews. The profile is unclaimed. For a platform with a public Discord community and multiple subscription tiers, the absence of any independent review record on Trustpilot is notable.
What Makes Unusual Whales Distinct
Most platforms in this category were built around options flow from the start. Unusual Whales was built around financial transparency. The congressional trading tracker is not an add-on feature. It is the platform’s founding purpose, and it remains one of the most developed implementations of STOCK Act disclosure tracking available to retail traders. Annual congressional trading reports from Unusual Whales have been cited in financial media coverage, with the 2024 report tracking performance across congress members and finding that only 32.2% beat the market in 2025.
That transparency mission carries through the rest of the platform. The options flow tool covers every transaction for every ticker across all US exchanges. The dark pool feed surfaces off-exchange and institutional transaction data. Insider trades and ETF flows are tracked alongside the congressional data. The underlying philosophy is that information previously available only to professionals should be accessible to anyone willing to look at it.
For traders interested specifically in unusual options activity and flow, that philosophy means the platform casts a wide net rather than filtering aggressively to surface only the most significant trades.
Options Flow Feed
The flow tool tracks every options trade placed across the entire US stock exchange. The documentation describes it as presenting all of this information in an easily readable table that can be customized to show data in multiple ways: daily put and call skews, flow by ticker, flow by sector, and daily sentiment on specific strikes.
Buy/sell side determination is explained directly in the FAQ. Side is inferred from where the transaction occurred relative to the bid/ask spread. If the transaction occurred at or closer to the current bid price, it is assumed the contract was sold. If at or closer to the ask price, it is assumed the contract was bought. The docs explicitly note this is an assumption, and that not all BUY orders are Buy to Open and not all SELL orders are Sell to Open.
Calls labeled bearish and puts labeled bullish appear in the feed. The FAQ addresses this clearly: a call labeled bearish means a large portion of activity on that strike was on the bid side; a put labeled bullish means the same. These labels assume trades are opening positions rather than closing ones.
Free users see flow data but with a delay. Buffet’s Buffet subscribers get flow data with a 15-minute delay. Super Buffet subscribers get live data feeds.
The platform also includes a Market Tide tool providing a high-level options overview showing real-time sentiment, net premium flow, and institutional positioning across major indices. Market Tide is described as tracking overall market direction through options activity, complementing the granular per-ticker flow with a macro-level view.
For traders specifically comparing options flow tools, the review of FlowAlgo and Cheddar Flow covers platforms with more focused flow products.
Unusual Options Alerts
Unusual alerts are generated by an algorithm that flags certain options chains due to their unusual nature. The docs state clearly that there is no human element behind the alerts. They are not recommendations to buy. Entry and exit decisions are entirely up to the trader.
Alerts are sent between 10am and 4pm EST. They are available on the website alert feed, on the mobile application, and in the Discord server.
The distinction between premium and free alerts is explained in the FAQ. When the algorithm detects unusual activity, it places the alert into one of two queues. The premium alert queue takes priority over the free queue. If the premium queue is full, alerts go to the free queue. Premium users receive all alerts with zero delay. Free users receive only free alerts with a 5-12 minute delay. The docs note there is nothing fundamentally different about premium and free alerts.
Stock alerts and SPAC alerts are also available in addition to options alerts, accessible in the same alert feed on the website, mobile app, and Discord.
Dark Pool and Institutional Data
Dark pool data is available through the platform, covering off-exchange trading activity and large block trades executed on Alternative Trading Systems. The documentation describes real-time dark pool and institutional transaction data as part of the platform’s core offerings alongside the options flow feed.
The API documentation confirms dark pool endpoints cover recent dark pool trades and per-ticker dark pool trade history. Lit flow (on-exchange trades) is tracked separately from dark pool activity. The platform also provides open interest change feeds, showing how open interest shifts over time across the market and for individual tickers.
For institutional positioning, the platform tracks 13F filings from hedge funds and investment firms, surfacing what major institutions are buying and selling across their portfolios. ETF inflow and outflow data is also tracked, covering ETF-level positioning shifts.
Congressional Trading Tracker
The congressional trading tool is the platform’s most distinctive feature and its founding purpose. It tracks disclosures filed under the STOCK Act, which requires congress members and their immediate families to report stock trades within a statutory disclosure window. Members have up to 45 days to report, meaning the data is not real-time.
Unusual Whales publishes annual congressional trading reports. The 2024 report and the 2025 report are confirmed from the site. The 2025 report noted that only 32.2% of congress members beat the market, included analysis of trading patterns during tariff volatility and crypto legislation, and tracked record STOCK Act violations. These annual reports have received mainstream financial media coverage.
The politics section of the platform covers House trades, Senate trades, SCOTUS investing, and corporate lobbying. The congress tracker shows per-member trading dashboards, late filings, and recent trades. Per the API documentation, politician portfolio endpoints cover annual disclosures, portfolio holders by ticker, politician lists, and recent trades. This depth of congressional trading data is not available in this form on any other platform reviewed in this category.
Live Charting
The platform includes live charting for all US stocks with a variety of preloaded technical indicators. The documentation confirms VWAP, Bollinger Bands, and Ichimoku Clouds are among the available preloaded indicators. Price alerts for different types of price movement can be set within the charting tool.
The chart also integrates flow data directly. Options flow activity for any ticker can be viewed alongside the price chart, including a time-and-sales view for any individual options contract.
Options Profit Calculator
An interactive options profit calculator is included in the subscription tooling. Trades found in the flow feed can be plugged directly into the calculator without leaving the platform. The calculator allows traders to model the profit and loss of any options position before entering it.
Futures and Crypto Coverage
Unusual Whales covers futures market data including major indices (S&P 500, Nasdaq), commodities (Oil, Gold), and Forex pairs. CFTC futures data is also included. Crypto whale transactions are tracked as a separate data category, with recent crypto whale trade feeds available.
The API documentation confirms crypto endpoints for whale transactions, recent whale trades, crypto pair OHLC candles, and crypto pair state. This coverage extends the platform beyond pure equity options into a broader market data tool.
Mobile Application
Native iOS and Android applications are available. The docs describe the mobile app as providing enhanced access for Buffet’s Buffet subscribers and full access for Super Buffet subscribers. Alerts are accessible via the mobile application for all subscriber tiers. The free tier has a more limited mobile experience.
Discord Community and Bot
The Discord server is free to join at discord.gg/unusualwhales. Subscribers can link their Discord accounts in the platform settings to gain access to subscriber-only channels. All subscribers regardless of tier have access to the same subscriber channels once linked. The subscriber channels include: a channel directory with basic resources, the premium unusual options feed, a questions channel for platform and trading questions, general subscriber chat, a flow discussions channel for sharing and discussing flow findings, and a market chat channel.
A Discord/Twitter bot is also available for sending alerts to external Discord servers. The bot provides commands for receiving various types of options information directly in any Discord server.
The API
Unusual Whales offers a developer API with 100+ endpoints covering options flow, dark pool, congressional trading, Greek exposure, volatility, stock fundamentals, technical indicators, and more. Connection options include REST, WebSocket, Kafka, and an MCP Server. Historical option trades data is available at $250/month for the full market, with a 10% discount for subscriptions longer than one year.
The API covers 8,000+ tickers based on the developer-facing documentation. Enterprise and professional subscriptions are available upon request at dev@unusualwhales.com. The breadth of the API is substantial, with endpoints for everything from dark pool and flow to prediction markets and crypto whale transactions. For developers building on top of market data, the Unusual Whales API is one of the most comprehensive documented option available at this price point.

Trustpilot and External Validation
Unusual Whales has a Trustpilot profile with 0 reviews, unclaimed as of April 2026. The platform does not appear to have cultivated a public review record on Trustpilot. Given the size of its Discord community and the volume of subscriber activity visible on the platform’s social media presence, the absence of reviews reflects a choice not to actively solicit or curate that channel rather than a lack of user base.
The congressional trading reports have received mainstream press coverage, providing an alternative form of external validation. The platform’s data has been cited in financial journalism.

Bottom Line
Unusual Whales is the right platform for traders who want breadth across data types rather than depth in a single flow product. The combination of live options flow for every US ticker, dark pool data, congressional and insider trade tracking, 13F institutional data, futures, crypto whale transactions, and a developer API under a single subscription is unmatched at this price point.
The congressional trading tracker alone has no equivalent in the category. For traders who want to combine flow analysis with an understanding of how insiders and politicians are positioning themselves, Unusual Whales provides that context in one place.
The weakness is the same as its strength: coverage is extremely wide, which means traders looking for a focused, deeply-filtered flow product with aggressive signal isolation may find the platform less opinionated than alternatives like FlowAlgo or SpotGamma. The free tier is a genuine starting point, not a marketing vehicle, and provides enough access to assess whether the approach fits a specific trading workflow before committing to a paid plan.
FAQ
Is Unusual Whales data real-time?
Super Buffet subscribers receive live data feeds with no delay. Buffet’s Buffet subscribers receive flow data with a 15-minute delay. Free Shamu users see delayed flow data with limited access. The docs state that all live data is subject to the OPRA Nonprofessional agreement, which governs retail access to real-time options data.
How does Unusual Whales determine whether an options trade is a buy or sell?
Side is inferred from transaction price relative to the bid/ask spread. If the transaction occurred at or closer to the current bid, the contract is assumed sold. If at or closer to the ask, it is assumed bought. The docs explicitly note this is an assumption, and that not all buys are Buy to Open and not all sells are Sell to Open. The FAQ advises always verifying via the alert page to confirm buy or sell side.
What is the refund policy?
No refunds are available once payment has been processed, per the terms of service. Plans auto-renew by default. To cancel autorenewal, subscribers must select “End Autorenewal” on the billing page at least 24 hours before the next renewal date. Subscribers who signed up via PayPal must cancel their subscription on the PayPal website directly.
What makes the congressional trading tracker different from other platforms?
Unusual Whales built congressional trading tracking as its founding purpose, not as a supplementary feature. The tracker covers House trades, Senate trades, SCOTUS investing, and corporate lobbying. Annual reports analyzing congressional trading performance are published by the platform. The 2025 report found that only 32.2% of congress members beat the market that year and tracked STOCK Act violation records. Per-member dashboards, late filing tracking, and recent trade feeds are all available within the platform.
What is Market Tide?
Market Tide is Unusual Whales’s high-level options overview tool, showing real-time sentiment, net premium flow, and institutional positioning across major indices. It provides a macro-level directional view built from aggregate options activity rather than per-ticker flow, giving traders a sense of overall market direction through the options market alongside the per-ticker live flow feed.
Does Unusual Whales offer an API?
Yes. The Unusual Whales API provides 100+ endpoints covering options flow, dark pool, congressional trading, Greek exposure, volatility, stock fundamentals, technical indicators, prediction markets, and crypto whale transactions. Connection options include REST, WebSocket, Kafka, and an MCP Server. Historical option trades data is available at $250/month for the full market. Enterprise and professional subscriptions with redistribution licenses are available via dev@unusualwhales.com.
What does the free tier include?
The Free Shamu tier includes limited delayed flow data, the free flow alert feed, delayed unusual options alerts, and public Discord access. No credit card is required to create a free account.
