Key Takeaways
  • • Unusual Whales has ended its partnership with Subversive Capital Advisor on two congressional trading ETFs (NANC and GOP), with Subversive ceasing its advisory role effective August 2, 2024, and is now partnering with Siebert Financial to launch a new series of ETFs based on political trading data.
  • • The Subversive Congressional Democrats Trading ETF (NANC) has accumulated $195–$260 million in assets under management since its February 2023 launch, significantly outperforming the Republican-focused GOP fund, despite charging expense ratios of 0.72–0.74%—substantially higher than traditional index funds.
  • • The ETFs track publicly disclosed stock trades by members of Congress and their families under the STOCK Act, mirroring congressional portfolios to provide retail investors access to legislative trading activity as a market intelligence signal.
  • • Siebert Financial's new partnership with Unusual Whales combines the latter's market intelligence platform—which tracks congressional and political trading disclosures, unusual options activity, and institutional flows—to develop enhanced ETF offerings for institutional and retail investors.
  • • The shift from Subversive to Siebert represents a strategic realignment in the political trading ETF space, with Tidal Financial reportedly assuming operational responsibilities following the original partnership dissolution.
Summary
Unusual Whales, the retail-focused platform known for aggregating and publicizing congressional stock trading disclosures, has formally dissolved its partnership with Subversive Capital Advisor on two politically themed ETFs and announced a new strategic collaboration with Siebert Financial to develop a fresh series of ETF products. Regulatory filings confirm that Subversive Capital ceased its advisory role effective August 2, 2024, though the announcement was made public via social media channels more recently.

The original ETFs—the Subversive Congressional Democrats Trading ETF (ticker: NANC) and the Subversive Congressional Republicans Trading ETF (ticker: GOP, originally KRUZ before rebranding in March 2025)—launched in February 2023 to significant market attention. Both funds operationalize a straightforward concept: members of Congress must disclose their equity purchases under the STOCK Act, and those disclosures are public record. The ETFs convert this data into actively managed portfolios that track the buying patterns of Democratic and Republican legislators respectively. NANC has substantially outperformed GOP in asset accumulation, holding an estimated $195–$260 million compared to GOP's smaller asset base. Both funds charge expense ratios between 0.72% and 0.74%, a premium significantly higher than passive S&P 500 index alternatives that typically charge 0.03%–0.10%, reflecting their active management and concentrated portfolio construction.

Unusual Whales' new partnership with Siebert Financial combines the former's proprietary market intelligence platform—which tracks congressional and political trading disclosures, unusual options activity, institutional flows, and related market signals—with Siebert's ETF infrastructure and distribution capabilities. This collaboration aims to develop and launch an enhanced series of politically focused ETF products, broadening Unusual Whales' reach beyond its core retail audience. The transition follows Tidal Financial's assumption of certain operational responsibilities related to the existing funds.

The strategic realignment underscores persistent investor demand for alternative data sources and non-traditional portfolio construction methodologies. Congressional trading data remains a legitimate, legally accessible intelligence source for market participants seeking edge through legislative positioning signals, though the historical performance and tax efficiency of such concentrated portfolios remain open questions for institutional evaluation.
