US spot Bitcoin ETFs logged a $1.039 billion net outflow in the trading week of May 11–15, breaking a six-week run of net inflows that had pulled sustained institutional capital into the asset class. Every major US spot BTC fund participated in the reversal.
Why it matters
The streak was the clearest signal of structural US institutional bid since launch; one down week doesn't erase it, but it does reset the narrative. The simultaneous $255 million weekly net outflow from spot Ethereum ETFs compounds the read — risk-off across the complex, not a single-fund rotation.
Market impact
The two majors bled while the newer products gained ground: spot SOL ETFs pulled a $58.12 million net inflow and spot XRP ETFs added $60.50 million, the first meaningful institutional pulse for both wrappers. Watch next week's flow tape — a second consecutive outflow prints would shift the read from "positioning" to "trend."

What should investors watch after this outflow week?
The next weekly flow tape is the key signal: a second consecutive net outflow would shift the read from short-term positioning to a developing trend, while a return to net inflows would mark the latest week as noise.
