Woofun AI reports that a sharp reversal in momentum occurred on July 13, as Bitcoin ETFs experienced significant capital flight that erased recent gains, with FBTC and IBIT emerging as the primary drivers of this negative shift.

The financial impact was immediate and substantial, with net outflows reaching $424.7 million in a single session. This figure more than doubled the $197.4 million accumulated during the preceding five trading days. Consequently, the cumulative balance for the period spanning July 6 through July 13 settled at negative $227.3 million. This outcome effectively failed the initial follow-through test required to confirm a break from the previous eight-week outflow streak.

Woofun AI data shows the specific mechanics behind these withdrawals remain opaque regarding seller identity, potentially involving retail investors, financial advisers, or institutions. It is also unclear whether every dollar exiting a Bitcoin ETF corresponded to an immediate sale on the open market. The concentration of losses in FBTC and IBIT suggests the prior week's positive total was driven by a single fund rather than a broad-based rebound in ETF demand.

To offset Monday's $424.7 million outflow, the funds must attract an equivalent amount over the remaining sessions to finish the week flat. Matching the previous week's $197.4 million net inflow requires generating $622.1 million in new capital. The distribution of these potential inflows across issuers will be critical; a broad rebound would signal genuine demand recovery, whereas another negative week or isolated gains would indicate that the first positive week in nine was merely a pause in the broader outflow trend.
