What Happened?
Bitcoin exchange-traded funds (ETFs) in the US recorded a sharp turnaround on Tuesday, pulling in $355 million in net capital. This marks the second-largest single-day net inflow in December and puts an end to a seven-day outflow streak that had weighed heavily on market sentiment.
Leading the charge was BlackRock’s iShares Bitcoin Trust (IBIT), which brought in over $143 million. The inflow comes after IBIT had previously experienced $449 million in outflows since December 23. Other major ETFs, including ARK 21Shares and Fidelity, also saw robust inflows, suggesting a resurgence of institutional demand.

Bitcoin ETFs Break Outflow Streak
The December 30th activity marks a clear shift in investor behavior. According to data from SoSoValue:
- BlackRock (IBIT): $143.75 million inflow
- ARK 21Shares (ARKB): $109.56 million inflow
- Fidelity (FBTC): $78.59 million inflow
- Bitwise (BITB): $13.87 million inflow
- VanEck (HODL): $4.98 million inflow
- Grayscale (GBTC): $4.28 million inflow
None of the ETFs reported selling Bitcoin that day, further underlining the strong demand.
While Tuesday alone accounted for $355 million in inflows, the weekly net flow also turned positive, reaching $335.73 million. December as a whole has been rough, with monthly outflows still totaling $744.49 million, but Tuesday’s surge indicates momentum may be shifting.
Bitcoin Price Hovers Near $89K
The ETF inflows arrived just as Bitcoin briefly crossed the $89,000 mark before settling at $88,729. The price increase, although modest, likely helped reinforce investor confidence.
Bitcoin has traded between $87,000 and $90,000 for most of the past few weeks, failing to break out decisively since December 13. Analyst Ted Pillows commented that the yearly candle may still close in red, but noted that institutional buying zones remain strong.
Ethereum, XRP, Solana Also Show Movement
While Bitcoin ETFs led the day, other crypto-based ETFs also showed signs of life:
- Ethereum (ETH) ETFs had net outflows of $67.84 million, continuing a volatile month.
- XRP Spot ETFs gained $15.5 million in inflows.
- Solana (SOL) Spot ETFs added $5.21 million.
- Dogecoin (DOGE) Spot ETFs saw smaller inflows of $288,130.
These trends suggest that institutional interest isn’t just limited to Bitcoin, though BTC remains the primary vehicle.
CoinLaw’s Takeaway
I’ve seen how fast sentiment shifts in crypto, and this is one of those moments. After a sluggish December and a stream of outflows, Tuesday’s $355 million reversal feels like a wake-up call from institutional investors. BlackRock stepping back in with $143 million is no small feat, and ARK’s record daily inflow speaks volumes too. In my experience, when the giants start moving again, the rest of the market tends to follow. If this momentum keeps up, we could be at the early stages of another strong institutional wave into crypto assets.
