Bitcoin News Today: Redefining Risk: IBIT's $100B Leap Challenges Traditional Finance

BlackRock's iShares Bitcoin Trust (IBIT) is on the brink of a historic milestone, nearing $100 billion in assets under management (AUM) as of early October 2025. The ETF, launched in January 2024, has surged to become the firm's most profitable product, generating an estimated $244.5 million in annual revenueBlackRock Bitcoin ETF (IBIT) nears $100 Billion in AUM^[1]. This growth is attributed to Bitcoin's price rally-surpassing $125,000 in late September-and robust institutional and retail inflows. IBIT now accounts for over half of all U.S. spot Bitcoin ETF inflows, with $97.8 billion in AUM as of October 6IBIT Turns Into BlackRock’s Biggest Moneymaker Yet^[2].

The fund's trajectory has outpaced traditional benchmarks. Whereas Vanguard's S&P 500 ETF (VOO) took over 2,000 days to reach $100 billion, IBIT is projected to achieve the same in less than 435 daysBlackRock’s Most Profitable ETF (IBIT) Is a Nearly $100-Billion Giant^[3].

However, the ETF's success has introduced market risks. Large inflows into IBIT and other Bitcoin ETFs have amplified price volatility. For instance, a $3.9 billion transfer of dormant Bitcoin wallets in early October triggered $620 million in liquidations, causing a 4% drop in Bitcoin's priceWhale Awakening: $3.9 Billion Bitcoin Shift Triggers $620 Million Liquidations^[5].

The ETF's profitability also raises structural questions. BlackRock earns 0.25% in fees on IBIT's AUM, directly linking its revenue to Bitcoin's performance. While this model has proven lucrative, it exposes the firm to downside risks if Bitcoin faces prolonged corrections. Additionally, the fund's dominance-outpacing older, larger BlackRock ETFs like the iShares Russell 1000 Growth ETF (IWF)-highlights a shift in investor priorities toward digital assetsU.S. BTC ETFs See $1B Inflows, Seen 6 Times Before^[7].
