The battle between the world’s largest Bitcoin ETF issuers has entered a dramatic new phase. While Grayscale continued selling Bitcoin this week, BlackRock moved in the opposite direction with aggressive accumulation. The contrast surprised traders and reignited discussions about institutional confidence in Bitcoin’s long term future.
Fresh market data revealed that Grayscale sold nearly $62.3 million worth of Bitcoin since Monday. At the same time, BlackRock purchased more than ten times that amount. The asset management giant added roughly $623.5 million worth of BTC during the same period. This massive buying activity pushed BlackRock Bitcoin holdings above an incredible $64.85 billion.
The scale of BlackRock’s accumulation continues turning heads across the crypto industry. The company now controls nearly 3.87% of the entire Bitcoin supply. That number highlights how quickly Wall Street firms are gaining influence over the digital asset market. Many analysts now believe institutional accumulation could become one of BTC strongest bullish catalysts in 2026.

BlackRock’s iShares BTC Trust has emerged as one of the strongest forces in the crypto ETF sector. The fund continues attracting massive capital while competitors struggle to keep pace. Recent numbers show the company dominating weekly BTC ETF inflows by a huge margin.
Investors appear drawn toward BlackRock’s scale, reputation, and operational strength. Many institutional firms prefer established financial giants when entering emerging markets like crypto. That trust factor continues helping BlackRock absorb billions in fresh BTC exposure.
The recent buying spree also shows how quickly ETF demand can impact Bitcoin markets. BlackRock purchased over $623 million worth of BTC in just a few days. Such aggressive accumulation reduces available circulating supply and increases pressure on sellers.
While BlackRock attracted billions in fresh demand, Grayscale continued seeing outflows from its Bitcoin products. The company sold approximately $62.3 million worth of BTC since Monday, extending a trend that started months ago.
Many investors continue rotating out of Grayscale products due to fee structures and competition from newer ETFs. Lower cost alternatives now dominate investor attention. BlackRock especially benefits from this migration trend because of its strong brand recognition and aggressive expansion strategy.
Grayscale once dominated institutional BTC investing. However, the market changed quickly after spot Bitcoin ETFs entered mainstream finance. Investors now have multiple choices with lower fees and higher liquidity.
Bitcoin’s fixed supply remains one of its most powerful features. Only 21 million BTC will ever exist. As institutions continue buying aggressively, available supply on exchanges may shrink further.
BlackRock already controls nearly 3.87% of the total BTC supply. That figure becomes even more significant when combined with holdings from other major ETF issuers. Together, institutional funds now own substantial portions of circulating Bitcoin.
Reduced exchange supply often creates stronger upward price pressure during periods of rising demand. If buying activity accelerates while supply remains constrained, Bitcoin prices could react sharply.
BlackRock’s latest buying spree delivered another powerful signal to the crypto market. While Grayscale sold millions in Bitcoin, BlackRock accumulated more than ten times that amount. The contrast highlighted the growing dominance of institutional capital inside digital asset markets.
The surge in Bitcoin ETF inflows also demonstrated how quickly traditional finance continues embracing Bitcoin exposure. Institutional investors increasingly treat BTC as a strategic long term asset rather than a speculative trade.

Aptos Foundation and Aptos Labs have committed $50 million to Aptos development, with a particular focus on AI agent infrastructure and research, including support for two products it shipped last year to meet rising demand for onchain AI agent activity. Those products include Decibel, an AI-powered onchain order book and perpetuals exchange that launched on the Aptos mainnet in February, and Shelby, a decentralized storage protocol that seeks to support the workloads of AI agents, the Aptos Foundation said on Thursday.“Autonomous agents are already transacting onchain at frequencies no human can match, routing to whatever venue is fastest, most consistent, and least gameable,” it said.Aptos joins a growing number of crypto protocols seeking opportunities in supporting the agentic AI economy. Aptos said there is a need to build infrastructure that offers sub-second finality and systems that “run 24/7 with no human to escalate to.”AI agents can act as personal assistants for people, both at home and in the workplace, completing everyday tasks on their behalf, whether it be booking a flight, making a shopping purchase or executing a high-level trade onchain.The Aptos ecosystem’s “full stack” plan for markets and machines. Aptos NetworkLast month, Coinbase CEO Brian Armstrong predicted there will be “more AI agents transacting online than humans very soon,” echoing comments from Circle CEO Jeremy Allaire in January that “literally billions of AI agents” will be transacting onchain in three to five years.The World Economic Forum is expecting a boom too, having predicted in January that AI agents could become a $236 billion market by 2034, a 43-fold rise from its $5.4 billion market size in 2024.AI agents use blue-chip stablecoins to transactOn Wednesday, Amazon Web Services said it integrated Coinbase’s x402 payments protocol into Amazon Bedrock AgentCore to allow AI agents to make USDC (USDC) payments and access services through AWS-managed payment controls. A week earlier, crypto wallet startup Oobit launched a Visa-supported virtual card for AI agents to make online purchases in USDt (USDT) on behalf of businesses. The foundation said the Aptos (APT) token would play a central role in the ecosystem’s AI agent economy by being burned in transactions, required to access advanced AI agent features, and staked to improve performance.

Aptos Labs founding engineer Sherry Xiao, told Cointelegraph that Confidential APT could help businesses hide the salaries of employees who are paid onchain, as well as conceal treasury movements, settlement flows and trading strategies that competitors could otherwise see.
