Spot ETF net inflows of $2.39 billion for the single week have pushed $BTC back into the spotlight. Breaking down the five-day rhythm of capital flows, the distribution of liquidity shows a subtle discontinuity: inflows of $999 million on Monday, dropping to $715 million on Tuesday, then steadily fading to $134 million on Friday. The buy-side nearly halved day by day, with the first day consuming more than 40% of the week’s incremental gains.

This kind of funding trajectory—strong at the start and weakening afterward—bears a very pronounced concentrated replenishment characteristic. Compared with the prior week’s extreme contraction to just $6.21 million, this round of expansion quickly erased the previous shortfall, with IBIT alone absorbing about $1.2 billion. Although the total weekly trading value of nearly $15 billion has driven the year-to-date cumulative net inflow back into positive territory at $925 million, the spot price has not yet broken out decisively in one direction.

The real test lies in whether the depth and continuity of liquidity can be maintained. After the last time a single-week capital pulse of a similar magnitude appeared, the market afterward fell into a prolonged consolidation. Now, if the spot channel cannot re-stabilize the buy-side slope after the decline in the second half of the week, the “vacuum” of follow-through after the tide of concentrated replenishment retreats will be the challenge the market must face next.
