U.S. spot bitcoin ETFs took in roughly $550 million across Monday and Tuesday, according to fund flow data, with the bulk of it landing in a single session. Monday's haul was $526.60 million. Tuesday added $23.16 million. The two-day total puts bitcoin funds back in the green after a stretch of uneven flows.
The split matters. Nearly all of the money came in on one day, and Tuesday's figure is small enough to read as a rounding error next to Monday's. That's not a broad, steady bid — it's one big allocation followed by a quiet tape.
A lopsided two-day tally
ETF flow data is reported a day in arrears, which is why the Tuesday print only surfaced now. The $526.60 million from Monday is the number that moves the needle. Tuesday's $23.16 million barely registers against it.
Issuers don't break out which funds captured the money in the headline figures. What's clear is the direction: net positive for bitcoin products, and decisively so on Monday.
Ether funds can't stop the bleed
The picture flips for ether ETFs. Outflows persisted through the same window, with no sign of the reversal that bitcoin funds managed. The gap between the two is widening — bitcoin products are attracting fresh capital while ether products keep shedding it.
Nobody's calling it a rotation yet. But when one asset's funds are pulling in half a billion dollars over two days and the other's are still leaking, the contrast is hard to ignore.
Solana's 12-session slide
Solana extended its losing streak to 12 consecutive sessions. That's the longest stretch of the three and the most one-directional. Twelve straight sessions of outflows is a pattern, not a blip.
The three data points together tell a simple story: money is concentrating in bitcoin ETFs and leaving almost everything else. Whether that holds past this week is the open question. Flow data for Wednesday and Thursday will show if Monday's big number was a one-off allocation or the start of something steadier.
