According to Matt Hougan, citing FarsideUK data, August ETF flows show BTC ETFs at net outflows of approximately $800 million and ETH ETFs at net inflows of about $4.0 billion (source: Matt Hougan on X, Aug 28, 2025; data source: FarsideUK). Hougan characterized this as a relentless bid for ETH, underscoring sustained demand in ETH-listed funds (source: Matt Hougan on X, Aug 28, 2025). The resulting $4.8 billion monthly flow differential in favor of ETH is a trade-relevant datapoint for tracking relative demand in the ETH BTC pair and ETF-driven spot liquidity, based on the FarsideUK figures referenced by Hougan (source: FarsideUK via Matt Hougan on X, Aug 28, 2025).
