Why it matters

02

Market read

03

What to watch

Context

Fidelity's Bitcoin ETF (FBTC) recorded $201.04 M of outflows, accounting for a major share of the total $643 M outflow.

Expected impact

likely pressure as investors exit the fund

Evidence & confidence

Substantial net redemption reduces assets under management and can trigger NAV decline.

$ARKBBearishMedium confidence
Context

ARK's Bitcoin ETF (ARKB) lost $129.55 M, contributing to the overall outflow concentration.

Expected impact

likely pressure as redemptions outweigh inflows

Evidence & confidence

Redemptions are sizable relative to recent inflows, suggesting short‑term weakness.

$GBTCBearishMedium confidence
Context

Grayscale Bitcoin Trust (GBTC) saw $53.32 M withdrawn, reflecting broader ETF outflow trends.

Expected impact

Evidence & confidence

Even smaller outflows add to market sentiment of risk aversion after the Binance hack.

$BITBBearishLow confidence
Context

Bitwise Bitcoin ETF (BITB) recorded $25.72 M of outflows, the smallest among the five highlighted funds.

Expected impact

likely pressure as net redemptions erode assets

Evidence & confidence

Outflow size is modest, but market‑wide sentiment could still affect price.

Market effects

Crypto‑related ETFs face heightened redemption risk, potentially spilling over to other digital‑asset funds.
