U.S. spot bitcoin exchange-traded funds logged a modest $4.89 million net inflow on Tuesday, a day when BlackRock's IBIT did the heavy lifting. The fund added $50.20 million, enough to offset outflows from five other bitcoin funds. Ether funds stayed slightly negative, while Solana ETFs drew fresh capital.
IBIT carries the day
BlackRock's IBIT was the clear outlier. It pulled in $50.20 million on Tuesday, a figure that dwarfed the net total for the entire category. Without that single fund, the bitcoin ETF group would have been in the red. The other five funds that saw outflows didn't get named in the data, but the math is straightforward: their combined redemptions came to roughly $45.31 million.
The net number is small — under $5 million — but the split is telling. One fund is absorbing nearly all the demand, while the rest are seeing money walk out the door. That's not a broad-based surge; it's a concentrated bet on a single product.
The rest of the pack
Five bitcoin funds reported outflows on Tuesday. The data doesn't break down which ones, but the pattern is familiar. Since the launch of spot bitcoin ETFs, flows have tended to cluster around the largest, most liquid products. Smaller funds often struggle to hold assets when the market wobbles.
Tuesday's outflows weren't catastrophic. The total net inflow, after all, was still positive. But the fact that five funds bled while one carried the day suggests investors are still picky about where they park their bitcoin exposure.
Ether and Solana diverge
Ether funds remained slightly negative, continuing a recent trend of soft demand. The numbers are small, but the direction is consistent — ether ETFs haven't been attracting the same kind of interest as their bitcoin counterparts.
Solana ETFs, by contrast, attracted fresh capital. The data doesn't specify how much, but the flow is positive. That's a notable divergence: bitcoin and ether are the established assets, yet Solana is the one pulling in new money. Whether that's a blip or a shift is unclear, but it's worth watching.
The next few days of flow data will show whether Tuesday's pattern holds — whether IBIT keeps absorbing demand, whether ether funds stay in the red, and whether Solana's momentum continues.
