The claim has not been independently confirmed through official fund disclosures or verified ETF flow trackers. The reported figure of $136.28 million is attributed solely to a Telegram post, and no additional sourcing or transaction data has surfaced to corroborate it at the time of writing.
What the Telegram Post Claims
The post alleges that the sale occurred through BlackRock’s Bitcoin-related holdings. BlackRock operates the iShares Bitcoin Trust (IBIT), one of the largest spot Bitcoin ETFs in the United States by assets under management.
No transaction hash, wallet address, or on-chain evidence has been provided alongside the claim. Without a verifiable block explorer link or official filing, the reported dollar amount remains unconfirmed.
Traders following Bitcoin ETF activity often monitor daily flow data published by trackers such as Farside Investors, which aggregates net inflow and outflow figures for U.S.-listed spot Bitcoin ETFs. Readers can cross-reference the claimed outflow against that dataset for verification.
Why BlackRock Bitcoin Flow Reports Draw Attention
BlackRock is the world’s largest asset manager, and its entry into the spot Bitcoin ETF market in early 2024 was widely viewed as a turning point for institutional adoption. Any reported movement in IBIT holdings tends to generate outsized attention relative to the dollar amount involved.
Large reported outflows from institutional products can shift short-term sentiment among traders, even before confirmation. This dynamic has played out in previous episodes where headline-driven selling pressure preceded verification of the underlying data, similar to how reports of major Bitcoin movements, such as the Winklevoss twins injecting $100 million in Bitcoin into Gemini, can move market narratives quickly.
The broader context of institutional Bitcoin flows has been a key market theme in 2026. Platforms tracking trading volume trends across prediction markets and ETF dashboards have become closely watched indicators for gauging whether large players are accumulating or distributing.
Verification Gaps Traders Should Watch
The distinction between a social media alert and confirmed market data is critical. Telegram channels frequently circulate unverified transaction claims that are later revised or retracted. Traders acting on unconfirmed reports risk positioning based on incomplete information.
For this claim to be treated as established, market participants would need to see at least one of the following: an official IBIT fund flow disclosure, matching data from an independent ETF flow aggregator, or an on-chain transaction visible on a Bitcoin block explorer such as Mempool.space or Blockchain.com.
Until additional confirmation emerges, the reported sale remains a single-source claim. Developments in institutional Bitcoin custody and transfers, including cases like Lombard Finance’s recent infrastructure changes for BTC-related assets, underscore why verification of large-value Bitcoin movements matters before drawing conclusions about market direction.
