Bitcoin spot ETFs are sending a key turning-point signal: the capital flow cycle has turned positive across the board for the first time, and the market structure has begun to reprice with a more bullish bias.

**Core change:** rolling capital flows have fully recovered. The latest data shows that **all tracked rolling-cycle capital flows have turned positive**, marking the first time in the past few months that they have turned positive in overall synchronized fashion.

This means ETF capital has shifted at the funding end from “intermittent outflows” to: a structure of **sustained net inflows**.

**Leading force:** institutional-led capital returning. Among them, BlackRock’s iShares Bitcoin Trust (IBIT) stands out especially: cumulative net inflows of about **$30 billion**, placing it in the **top 1%** tier by fund flows across all ETFs.

This is no longer just participation, but: **top institutions are reasserting control over marginal pricing**.
