Unusual Whales and Siebert Financial Announce Strategic Partnership to Launch New Series of ETFs

MIAMI and NEW YORK, Aug. 18, 2026 (GLOBE NEWSWIRE) -- Siebert Financial Corp. (NASDAQ: SIEB) (“Siebert”), a diversified financial services company, and Unusual Whales, a financial data and market intelligence platform, today announced a strategic partnership to develop and launch a series of exchange-traded funds (ETFs).

The partnership brings together two distinct strengths:

• Unusual Whales provides access to a different layer of market intelligence, including political trading disclosures, options activity, market flows and other forms of “shadow data” that can reveal activity and trends beyond traditional financial research; as well as a highly engaged follower base across social media, newsletters and exclusive chats, with more than 5 million followers on X/Twitter alone.
  
• Siebert provides the financial expertise, infrastructure, and market relationships needed to develop investment products and bring them to investors, thanks also to its circa $19 billion in Assets Under Management and more than 176,000 retail customer accounts.
  

Together, the companies intend to transform these insights into ETF strategies that give investors new ways to participate in themes and market activity that have historically been difficult to identify or access through traditional investment products.

“We are incredibly excited about what we can build with Unusual Whales,” said John J. Gebbia, CEO of Siebert Financial. “They have built a powerful window into parts of the market that investors increasingly want to understand, from political trading activity to signals that often sit outside traditional research. Siebert brings a solid financial infrastructure, 59 years of experience, and execution capabilities to turn those insights into real investment products. We believe the ETFs coming from this partnership can be unlike anything currently available to investors.”

Unusual Whales has built a large following by making complex and often hard-to-find market information easier for investors to access and understand. Its platform tracks areas including congressional and political trading disclosures, unusual options activity, institutional flows and other market signals that can provide a different perspective on where capital is moving.

“We built Unusual Whales around a simple idea: retail investors shouldn’t be the last ones to know what’s happening in the market. If politicians are trading, potential insiders are placing large bets, or unusual options activity is bubbling up beneath the surface, regular people deserve the tools to see it too,” said Matt Saincome, CEO of Unusual Whales. “This partnership with Siebert allows us to take insights pulled from our tools, data, and worldview and package them into more easily accessible ETFs with a partner who knows how to build, launch, and scale financial products at scale.”
The collaboration is designed to bridge the gap between market intelligence and investable products. The partnership also reflects Siebert’s broader strategy of combining its established financial infrastructure with emerging technology, data and new forms of market access.

Additional information regarding individual ETF strategies, regulatory filings and anticipated launch dates will be announced separately.
