TL:DR

Announced today, River, the Bitcoin-only U.S. exchange and financial services company, has officially revealed that it holds 437 BTC on its corporate balance sheet, making it the 9th largest private holder of BTC on BitcoinTreasuries.net. 

This matters because private company Bitcoin holdings are one of the most underreported segments of institutional adoption. Public companies file mandatory reports with the SEC and ETFs report daily. Private companies disclose only when they choose to, and most don't. When one does, it fills a gap that the rest of the market rarely sees. 

What's behind the numberWhat's behind the number

River publishes its financial statements voluntarily. The company reports a $68.1 million corporate treasury, zero debt, profitable operations, and a reserve ratio above 100% on client funds. No convertible notes, no ATM offerings. This is Bitcoin accumulated from operating revenue. 

Separately, River custodies over 25,000 BTC for clients, placing it #10 across all ETFs and exchanges we track. Among its customers, River has over 3,000 businesses on its platform buying bitcoin. 

Why it's on our radarWhy it's on our radar

River has been Bitcoin-only since 2019. It built its own custody and Lightning infrastructure, launched the first Bitcoin-only U.S. Proof of Reserves system, and publishes audited financials as a private company.  

Its adoption research, including the widely cited finding that over 50 million Americans own Bitcoin, has become reference material for institutional and policy audiences alike. 

That combination of transparency, focus, and self-reported holdings is exactly what makes private company data worth tracking.

Wonder if XXI will acquire them? 🤔 Wouldn’t mind having some River shares.
