Unusual Whales partners with Siebert Financial to launch new ETFs built on political trading data

Unusual Whales, the market intelligence platform best known for tracking what members of Congress buy and sell, is joining forces with Siebert Financial to create a new lineup of exchange-traded funds. The partnership pairs Unusual Whales’ political trading data and options flow analytics with Siebert’s brokerage infrastructure and roughly $19 billion in assets under management.

What the deal looks like

Siebert Financial Corp. (NASDAQ: SIEB) brings nearly six decades of Wall Street credibility to the table. The firm has been a presence on the New York Stock Exchange since 1967 and services over 176,000 retail accounts through its brokerage and advisory operations.

Unusual Whales was founded around 2019-2020 and built its following by scraping public disclosures and surfacing patterns in political trading, unusual options activity, and institutional money flows. The company has amassed more than 5 million followers on X.

Neither company disclosed specific fund strategies, ticker symbols, expense ratios, or a launch timeline. Those details will presumably surface through future regulatory filings with the SEC.

Unusual Whales already knows this playbook

This is not the first time Unusual Whales has ventured into the ETF space. The platform previously launched politically themed funds, including the NANC Democratic Trading ETF and a Republican counterpart, built on the premise of mirroring congressional stock trades.

The STOCK Act of 2012 requires lawmakers to disclose securities transactions, but enforcement has been inconsistent, and the disclosures often arrive weeks after trades are executed. Unusual Whales built its brand by aggregating those filings and making them searchable.

The new partnership with Siebert suggests Unusual Whales is looking to expand beyond its earlier politically themed offerings. The announcement referenced not just political data but also options flows and institutional activity, hinting at a broader product suite.

Why this matters for the ETF landscape

Legislation to ban or restrict congressional stock trading has been introduced repeatedly in recent sessions, though none has passed. If stricter rules eventually take effect, the underlying data powering these ETFs could change significantly, or even disappear.
