World's Largest Bitcoin ETF Sees 5 Trillion Won Vanish Amid Bitcoin Correction

iShares Bitcoin Trust ETF (NASDAQ: IBIT) closed at $50.76 on the 20th, plunging 6.42% from the previous day.

With a market capitalization of about $70.2 billion (approximately KRW 90 trillion), IBIT saw roughly $4.2 billion (around KRW 5 trillion) evaporate in a single session. Trading volume surged to 38.67 million shares amid heavy selling pressure.

Managed by BlackRock, IBIT surpassed $40 billion in net inflows by January 2025 and broke through $60 billion in assets under management within a year of its launch. By January 2026, it had absorbed more than 70% of all funds flowing into U.S. spot Bitcoin ETFs, further cementing its market dominance.

According to BlackRock’s filings, as of January 16, 2026, IBIT’s assets under management stood at about $74.5 billion, driven by recent Bitcoin price gains and continued ETF inflows.

Launched in January 2024 as BlackRock’s first U.S.-listed spot Bitcoin ETF, IBIT is designed to track the spot Bitcoin price index, offering investors a convenient way to gain Bitcoin exposure through their brokerage accounts. Since its debut, it has outpaced competing products to become the largest Bitcoin ETF and is regarded as one of the fastest-growing ETFs ever, thanks to its aggressive capital inflows.
