Bitcoin News Today: BlackRock's IBIT Surpasses S&P ETFs, Drives Bitcoin's $100B Milestone in 435 Days

Bitcoin's recent price surge to all-time highs of $126,000 has been fueled by record inflows into spot Bitcoin ETFs, with BlackRock's iShares Bitcoin Trust (IBIT) leading the charge. The fund recorded $3.5 billion in weekly inflows during the first week of October 2025, surpassing total net ETF flows of the top S&P 500 ETFs by 10%. This marks the largest inflow since November 2024 and underscores Bitcoin's growing institutional adoption. IBIT's dominance is further highlighted by its $5.7 billion daily trading volume on October 7, contributing to a $3.24 billion net inflow across all U.S. Bitcoin ETFs for the week. The fund now holds nearly $100 billion in assets under management, growing from inception to this milestone in just 435 days-far outpacing the 2,011 days it took the Vanguard S&P 500 ETF (VOO) to reach the same threshold *BlackRock’s Bitcoin ETF (IBIT) Shatters Records with $3.5B Inflows*^[1].

The surge in ETF inflows has directly correlated with Bitcoin's price action. On October 6, the cryptocurrency briefly touched $126,080 before consolidating around $122,000. Analysts attribute this momentum to thinning liquidity on traditional exchanges and a "supply shock" as whales withdraw BTC for long-term holding. Technically, the $120,000 level has become a critical support, with the 200-day EMA at $107,500 acting as a long-term floor. Institutional demand has also outpaced new Bitcoin supply by 7.4 times, signaling a structural shift in market dynamics *U.S. Bitcoin ETFs Log $1B Inflows Again, a Level That’s Marked Local Tops*^[2].

Bitcoin's ETF-driven rally has outperformed historical benchmarks. Past institutional inflows into products like Grayscale's GBTC influenced prices, but the scale and sustainability of current ETF demand are unprecedented. For instance, IBIT's $1.2 billion inflow on October 6-the second-largest single-day inflow-coincided with a $126,296 price peak. Historically, such inflows have aligned with short-term price tops, as seen in 2024 and 2025. This pattern suggests continued institutional confidence, with IBIT now generating $244.5 million in annual revenue for BlackRock *Bitcoin Shatters Records, Surpassing $125,000 as ETFs Fuel Historic Rally*^[3].

The broader market response to Bitcoin's ascent has been mixed. While the crypto community celebrates the "digital gold" narrative, altcoins have lagged, with Bitcoin dominance remaining elevated. DeFi protocols and NFT projects have seen modest gains, but the primary driver of capital inflows remains Bitcoin's ETF-driven legitimacy. Standard Chartered analysts project Bitcoin could reach $200,000 by year-end if inflows persist, while JPMorgan revised its target to $165,000 *Bitcoin Price: BTC Breaks $125,000 All-Time High as Record ETF Inflows Surge*^[4].

Regulatory and macroeconomic factors further bolster Bitcoin's bullish trajectory. The U.S. government's shifting stance, including President Trump's 2025 executive order on crypto, has normalized institutional adoption. Meanwhile, a weakening U.S. dollar-down 12% year-to-date-has increased Bitcoin's appeal as a hedge. Analysts also note that Bitcoin's volatility has declined from 4.2% (pre-ETF era) to 1.8%, reflecting reduced speculative trading and greater institutional participation *U.S. Bitcoin ETFs Log $1B Inflows Again, a Level That’s Marked Local Tops*^[5].

Looking ahead, the approval of Ethereum and potential Solana/XRP ETFs could expand institutional exposure beyond Bitcoin, triggering broader market rallies. BlackRock's IBIT nearing $100 billion in AUM and the SEC's proactive regulatory approach suggest continued ETF growth. However, risks remain, including regulatory uncertainty or macroeconomic downturns. Most analysts, though, view Bitcoin's current trajectory as a transformative phase for crypto, with $150,000–$200,000 price targets by mid-2026 appearing increasingly plausible *BlackRock Bitcoin ETF Tops S&P 500 Funds With $3.5B Inflows*^[6].
