How is BlackRock’s IBIT driving Bitcoin’s momentum?
BlackRock’s IBIT is the largest driver of institutional Bitcoin demand, contributing the biggest share of daily spot ETF inflows and controlling a disproportionate share of options open interest. This concentration has pushed ETF holdings to roughly 6.6% of circulating BTC and reinforced bullish price pressure.
What do ETF inflows and options activity reveal about institutional demand?
ETF inflows show steady accumulation: U.S. spot Bitcoin ETFs recorded $429.96 million in 24-hour inflows, with IBIT contributing $199.43 million. Options metrics are equally telling — Total Open Interest Delta reached $10.65 billion and the Call/Put Ratio climbed to 4.4, indicating heavy bullish positioning.

IBIT options volume surges — what does the derivatives market show?
The options market displayed a pronounced bullish tilt. Total Open Interest Delta reached $10.65 billion at press time, with the Call/Put Ratio near 4.4 — more than four times neutral — signaling that calls far outnumber puts.
IBIT controlled over 95% of this Open Interest Delta, valued near $10.45 billion. By comparison, Grayscale’s exposure stood close to $200 million, according to SosoValue.

Why does IBIT’s ETF dominance matter for price discovery?
IBIT accounted for more than 50% of the U.S. spot Bitcoin ETF market and represented 3.84% of the circulating Bitcoin supply. High concentration in a single product can magnify price moves as large inflows require executing through underlying markets.
Bloomberg analyst Eric Balchunas described the scale as unprecedented, noting that an equity ETF would need roughly $2.2 trillion to match similar ownership of its underlying assets for comparison.
In the past 24 hours, U.S. spot Bitcoin ETFs recorded $429.96 million in inflows, with IBIT contributing $199.43 million. That reinforced its role as the leading driver of institutional demand.

When could broader market data confirm sustained upside?
CryptoQuant data showed the Funds Market Premium flipped positive at a 0.24 reading, reflecting stronger bid pressure. Total ETF holdings hovered near 1.3 million BTC, and daily trading volume topped $4.6 billion.
At press time, Bitcoin traded near $116,228, with $120,000 within reach if momentum persisted and ETF-driven bids continued to absorb available supply.

Frequently Asked Questions
How much of Bitcoin does IBIT hold?
IBIT holds approximately 3.84% of circulating Bitcoin, making it the single largest institutional holder among U.S. spot ETFs and a material force in price formation.
Are ETF inflows driving the current rally?
ETF inflows are a major contributor: U.S. spot Bitcoin ETFs added roughly $430 million in 24 hours, and institutional products like IBIT are absorbing available supply and supporting higher bids.
What do options metrics imply about near-term risk?
A high Call/Put Ratio (about 4.4) and elevated Open Interest Delta ($10.65B) indicate strong bullish bets; however, concentrated positioning can increase short-term volatility on any surprise flows or option expiries.
