BlackRock’s bitcoin ETF has quietly pulled off something few Wall Street watchers expected: it’s outperforming one of the most trusted benchmarks in traditional investing. The BlackRock bitcoin ETF returns since its 2024 debut have edged past those of Vanguard’s S&P 500 fund, according to Bloomberg data cited by senior ETF analyst Eric Balchunas, a comparison that says as much about crypto’s arrival on Wall Street as it does about bitcoin’s price swings.
Summary
Key takeaways
- BlackRock’s iShares Bitcoin Trust (IBIT) has returned 71% since launching in January 2024, compared with 66% for Vanguard’s S&P 500 ETF over the same stretch.
- IBIT now manages $61.4 billion in assets, making it the largest bitcoin ETF by far, ahead of Fidelity’s Wise Origin Bitcoin Fund at nearly $11 billion.
- The fund launched after the SEC approved 11 spot bitcoin ETFs in 2024, ending a decade of rejected applications.
- Investors poured over $2.8 billion into bitcoin ETFs between August 17 and 27, 2026, the strongest inflow stretch since October.
- Bitcoin recently touched $81,281 before slipping to around $77,539, still up nearly 30% over the past month.
BlackRock Launches Leading Bitcoin ETF in 2024
BlackRock’s entry into the bitcoin ETF market wasn’t just another product launch — it was the moment regulators finally let one of the world’s biggest asset managers put crypto exposure inside a familiar, regulated wrapper. That shift reshaped how everyday investors could access bitcoin, and it set the stage for the performance numbers now turning heads on trading desks.
SEC Approval Unlocks Spot Bitcoin ETFs
None of this would have happened without a regulatory green light. The Securities and Exchange Commission approved 11 spot bitcoin ETFs in 2024, clearing a path that had been blocked for roughly a decade despite repeated applications from asset managers. This approval marked a genuine turning point in how US regulators treated crypto-linked products, effectively opening the gates for institutional-grade bitcoin investment inflows through traditional brokerage accounts.
IBIT Launch and Market Position
BlackRock’s iShares Bitcoin Trust (IBIT) began trading in January 2024, and it wasted little time establishing itself as the dominant player. The fund now manages $61.4 billion in assets, according to BlackRock’s own figures, dwarfing every other bitcoin ETF on the market. For context, the second-largest, Fidelity’s Wise Origin Bitcoin Fund, holds nearly $11 billion — less than a fifth of IBIT’s size. BlackRock itself oversees more than $15 trillion in total assets globally, a scale that helps explain why its entry into crypto sent ripples through the industry back in 2023 when the application first surfaced.
IBIT Outperforms Vanguard’s S&P 500 ETF Since Launch
Since its debut, IBIT has returned 71%, edging out the 66% total return posted by Vanguard’s S&P 500 ETF (VOO) over the identical period. That’s a modest gap on paper, but it carries outsized symbolic weight: a fund tracking a volatile digital asset has beaten one tracking America’s most established stock index, at least by this measure of iShares Bitcoin Trust performance.
Comparative Returns and Volatility
The two funds got to similar destinations through very different journeys. Balchunas described the contrast vividly, noting that reaching a 70% return with IBIT felt like riding a rollercoaster, while VOO’s climb was comparatively smooth. That’s a fair characterization of how bitcoin-linked products behave: sharp swings up and down, versus the steadier, more predictable path typical of a broad equity index fund. Investors chasing the headline return figures need to reckon with that difference in ride quality, not just the destination.
Expert Analysis on Performance Dynamics
Balchunas, BlackRock’s senior ETF analyst, put it directly in a post shared this week: “Hard to believe IBIT is beating VOO since inception but it’s true… altho it’s close. And to be fair, IBIT’s path to 70% looks like the El Toro roller coaster at Great Adventure (I needed two Advil last time I rode that thing) while VOO was a walk in the park in comparison.” The comment underscores a broader point about bitcoin ETF SEC approval and its aftermath — regulated access didn’t tame bitcoin’s volatility, it simply gave more investors an easy way to ride it, day-to-day trading swings included.
Investor Interest and Market Impact
Money has kept flowing back into bitcoin funds even as prices bounce around, and that steady demand is a big reason the BlackRock bitcoin ETF returns story keeps gaining attention. Renewed inflows in recent weeks suggest institutional appetite hasn’t cooled despite bitcoin’s price pulling back from its recent highs.
Bitcoin ETF Inflows and Trading Activity
Between August 17 and 27, 2026, investors funneled more than $2.8 billion into bitcoin ETFs — the largest wave of bitcoin investment inflows since October, when the coin hit a fresh all-time high. That momentum showed up again on a single trading day in early September, when US-listed spot bitcoin ETFs recorded $216.7 million in net inflows, reversing $201.8 million in outflows from the prior session, according to data from SoSoValue. IBIT alone accounted for $205.9 million of that total — roughly 95% of the entire category’s daily inflow, per Farside Investors. Fidelity’s fund added $6.9 million, Grayscale’s Bitcoin Mini Trust picked up $9.4 million, Bitwise’s fund gained $4.3 million, and Morgan Stanley’s Bitcoin Trust added $3.6 million. VanEck’s fund was the lone outlier, shedding $13.4 million. That single-session snapshot shows just how concentrated demand remains around BlackRock’s product, even when the broader category sees mixed flows.
Bitcoin Price Trends in 2026
Price action explains part of why investors keep circling back. Bitcoin reached as high as $81,281 recently before slipping on renewed selling pressure, with the price recently sitting around $77,539 — a dip of nearly 1% over 24 hours. Zoom out, though, and the bigger picture looks different: bitcoin has climbed nearly 30% over the past month, marking its strongest run in three years. That kind of rally tends to pull fresh capital toward ETFs like IBIT, reinforcing the fund’s lead over rivals and, by extension, its favorable comparison against traditional benchmarks like Vanguard’s S&P 500 fund.
