Spot Bitcoin ETFs record $457M inflows as institutions re-engage
U.S. spot Bitcoin ETFs posted a combined $457 million in net inflows, marking their strongest single-day intake in more than a month. The surge signals renewed institutional interest, supported by easing expectations around interest rates and a more favorable macro backdrop. Investors appear increasingly confident in gaining regulated exposure to Bitcoin through exchange-traded products, as market sentiment improved and risk appetite strengthened across digital assets.
Fidelity’s Wise Origin Bitcoin Fund (FBTC) led the advance, attracting approximately $391.5 million in fresh capital. BlackRock’s iShares Bitcoin Trust (IBIT) also recorded solid demand, adding around $111.2 million on the day. According to Farside Investors’ daily ETF flow tracker, the strong inflows highlight a clear concentration of institutional buying into the largest and most liquid Bitcoin ETF offerings.
Why it matters now
The fresh bid arrives after alternating inflow/outflow days in late November and early December. Since launch, cumulative net inflows have topped $57B, and category assets hover a little above $112–$113B, signaling continued long-only participation even after recent drawdowns.

Spot Bitcoin ETFs record $457M inflows: how it stacks up
Cumulative net inflows (since Jan. 2024): >$57B.
Category AUM (Dec. 17): ~$113B (tracker estimate).
Leadership concentration persists: FBTC and IBIT dominate daily flow tables.
Macro backdrop: rates and policy signals
In a national address marking his first year of a second term, President Donald Trump said he intends to nominate a Fed chair who favors “lower interest rates by a lot,” aligning with a broader narrative of easing into 2026. Such guidance typically supports risk assets.
On-chain context: overhead supply and fragile demand
Glassnode reports ~6.7M BTC in loss (7D-SMA), the most this cycle, with resistance overhead and a “true market mean” support zone near $81,300 a setup consistent with selective spot demand and defensive derivatives positioning.
Context & Analysis
Analysis: The combination of renewed ETF demand and an easing-bias narrative has historically buoyed crypto beta. Yet, Glassnode’s elevated loss-bearing supply implies rallies can be uneven until overhead supply is absorbed or new liquidity pushes price convincingly above resistance. Near-term, flow leadership remains concentrated in FBTC and IBIT, so any reversal in those two can quickly swing totals day to day.
Conclusion
The spot Bitcoin ETF market has just recorded its strongest single-day performance in more than a month, signaling a pickup in investor interest. Growing expectations of potential rate cuts and easing financial conditions could continue to support positive ETF inflows. As macro pressure softens, sentiment around regulated Bitcoin exposure appears to be improving among both institutional and long-term investors.
However, despite the constructive flow outlook, market volatility is likely to remain elevated. Bitcoin’s price action is still reacting to important on-chain resistance and support levels, while broader macroeconomic news and policy signals continue to influence short-term direction and trader behavior across the market.
