VolaIntel vs Quiver Quantitative

The short version

How Quiver Quantitative works

Quiver Quantitative describes itself as an alternative data platform: “Trade smarter with our cutting-edge alternative data platform.”. On Congress trades, its own page explains the method: “We download those disclosures, parse them for stock trades, fetch the stock's performance in the time following the transaction, and calculate each politician's cumulative return from their trades.”

Its menu lists Congress Trading, Insider Trading, Government Contracts, Corporate Lobbying, Institutional Holdings, a Politician Stock Portfolio Leaderboard and a Congress Backtester ("Build and test your own strategies, using Quiver's Congressional trading datasets"). (source). Its backtested results carry the note “The performance results shown are based on historical backtesting and are hypothetical in nature.”

On price: Its Pricing link (quiverquant.com/pricing/) opens the sign-up page; the website plan prices are not shown before you create an account. (source). The API is priced in public: Quiver API Hobbyist: $30.00 a month billed monthly, or $25.00 a month billed annually ($300 a year), including Congress Trading, Congress Stock Holdings and Politician Net Worth, with "No Commercial Use Rights". Quiver API Trader: $75.00 a month billed monthly, or $62.50 a month billed annually ($750 a year), adding Insider Trading, Hedge Fund Activity and ETF Holdings. (source). Its footer says tastytrade pays Quiver Quantitative compensation to recommend tastytrade's brokerage services (a marketing agreement). (source)

How VolaIntel works

VolaIntel is a politician and insider stock-trade tracker: a web and iPhone app from Opie Platforms Inc. that shows the stock trades members of the US Congress disclose under the STOCK Act, corporate insiders on SEC Form 4, large funds on Form 13F and 5% holders on Schedule 13D/13G, plus White House executive orders, with an AI assistant that answers questions from those filings.

Every row links the original filing. Congressional trades show the value range the member reported, and the date it was filed. The filing pages on this site are free to read; the app is VolaIntel Pro at $29.99 a year, and VolaIntel never places trades. See the Congress trading statistics and the trade return calculator.

Where they differ

Quiver gives you more datasets and tools to test ideas against them; VolaIntel gives you fewer sources, read for you, in one feed. A worked example on price: a year of Quiver's API Hobbyist plan is $300 billed annually, as of October 2026, and a year of VolaIntel Pro is $29.99. They are not the same product: the API is raw data for your own code, VolaIntel is an app.

When Quiver Quantitative is the better choice

• You want to backtest strategies on Congress trades, or pull the data into your own code through an API.
• You want datasets VolaIntel does not track, such as government contracts and corporate lobbying.
• You want a Politician Stock Portfolio Leaderboard that ranks politicians' portfolios by return.

When VolaIntel is the better choice

• You want Congress, insider, fund and 5% stake filings in one feed on your iPhone, with alerts for each kind of filing.
• You want a price you can see before signing up: $29.99 a year.
• You want every row linked to the original filing, with an AI assistant that answers from those filings.
