Unusual Whales and Siebert Financial are planning a new lineup of exchange-traded funds built around political trading disclosures, unusual options activity and institutional money flows, extending Unusual Whales' push to turn alternative market data into investable products. Siebert Financial Corp., listed on Nasdaq as SIEB, said on Aug. 18, 2026 that it would contribute its broker-dealer infrastructure, roughly $19 billion in assets under management, more than 176,000 retail customer accounts and nearly six decades of operating history. Unusual Whales, which has operated since 2019 and says it has more than 5 million followers on X and social media, brings the datasets and audience that helped popularize congressional trade tracking and options-flow analysis among retail traders. Siebert shares closed at $2.04, up 5.15% on the day and 21.43% over the past week, though still down 41.88% for the year. The companies did not disclose fund tickers, strategies, fees, launch dates or financial terms, leaving those details to future SEC filings. The announcement also comes as politically themed funds such as the Unusual Whales Subversive Democratic Trading ETF, or NANC, are already trading using disclosures required under the STOCK Act, a structure that depends on delayed public filings and could be affected if Congress ever bans lawmakers from trading individual stocks.
