Bitcoin ETFs Snap Inflow Streak as Missouri Reserve Law and Market Slide Hit

US spot Bitcoin ETFs broke a nine-day inflow streak on Friday, posting $201.8 million in net outflows as Bitcoin slipped back below $78,000. Total fund assets fell to $97.6 billion after briefly crossing $100 billion on Thursday. Despite the single-session reversal, August net inflows remained positive at $3.3 billion, underscoring the broader institutional appetite that has built throughout the month.

Altcoin ETF categories held up better than their Bitcoin counterparts, with Ether and XRP funds continuing to attract fresh capital even as Bitcoin consolidated. The wider crypto market dropped 2.9% on Saturday to a total capitalization of $2.72 trillion, with trading volume at $97.6 billion. Bitcoin's dominance held firm at 57.4% even as prices slipped to around $77,803, reflecting a market still digesting its sharpest three-week rally since 2023.

Missouri Launches State Bitcoin Reserve Under New Law

Missouri became the latest US state to formalize a Bitcoin reserve strategy when House Bill 2080 took effect on August 28. The law creates a Cryptocurrency Strategic Reserve Fund under the state treasurer, funded entirely through voluntary donations. Acquired Bitcoin must remain in offline cold storage for a minimum five-year holding period, barring any transfer or sale during that window.

The statute also protects independent node operators and staking participants, and complements existing Missouri rules that eliminated capital gains taxes on Bitcoin transactions. The move adds Missouri to a growing list of US states that have moved to codify Bitcoin holdings at the government level, signaling that the state-level reserve trend sparked earlier in the cycle is gaining legislative momentum heading into the final months of 2026.

The macro backdrop for both stories remains unsettled. Federal Reserve Chair Kevin Warsh addressed the Jackson Hole Symposium on August 28, with traders watching closely for any signal on the rate path. US inflation remains above the Fed's target, keeping higher-for-longer rate expectations in play. Bitcoin initially advanced from $64,000 to above $80,000 following the US Treasury's expansion of long-dated bond buybacks, a liquidity move that pressured the dollar and stoked inflation concerns that typically benefit hard-asset narratives.
