Quick Take
U.S. spot Bitcoin ETFs are close to surpassing $2 trillion in cumulative trading volume less than two and a half years after launching in January 2024.
BlackRock’s iShares Bitcoin Trust, known as IBIT, continues to dominate the spot Bitcoin ETF market, holding a 73.7% share of trading volume as of June 11.
The milestone comes as Bitcoin ETFs face mounting outflows, weaker market sentiment, and a sharp decline in the Bitcoin price from its October all-time high.
Spot Bitcoin ETFs Approach Historic $2 Trillion Milestone
U.S. spot Bitcoin exchange-traded funds are on track to cross $2 trillion in cumulative trading volume, marking one of the biggest milestones for crypto ETFs since their launch in January 2024.
Cumulative trading volume for U.S. spot Bitcoin ETFs reached $1.99 trillion as of June 11. Based on recent daily trading volumes of around $2 billion to $5 billion, the funds could pass the $2 trillion mark as early as Friday.
The growth has been rapid. Spot Bitcoin ETF trading volume first crossed $100 billion in March 2024, only two months after launch. By April 2024, the figure had doubled to $200 billion as Bitcoin climbed toward its then-record high near $74,000.
Bitcoin ETF Trading Surged After Trump’s Election Victory
Momentum accelerated again after Donald Trump’s pro-crypto U.S. presidential election victory in November 2024. Bitcoin moved to fresh all-time highs, while spot Bitcoin ETFs quickly surpassed $500 billion in cumulative trading volume.
The sector then continued to expand through 2025. U.S. spot Bitcoin ETFs reached $750 billion in cumulative volume in February 2025 before crossing the $1 trillion level around one year ago.
Now, with the $2 trillion mark within reach, spot Bitcoin ETFs have become some of the most actively traded ETF products in the world. Their trading activity places them alongside major traditional ETF names such as the Vanguard S&P 500 ETF, VOO, and the Invesco QQQ Trust, which tracks the Nasdaq-100 Index.
Bitcoin ETFs Outpace Ethereum, Solana, XRP and Hyperliquid Funds
The scale of U.S. spot Bitcoin ETF trading remains far ahead of newer crypto ETF products.
Spot Ethereum ETFs, which launched in July 2024, have generated $466.3 billion in cumulative trading volume so far. Solana ETFs have reached $10.5 billion, while XRP ETFs have recorded $4 billion. The more recent Hyperliquid ETFs have generated $838.6 million in cumulative trading volume.
This gap shows that Bitcoin remains the leading asset for institutional crypto ETF demand, even as more digital asset ETFs enter the U.S. market.
BlackRock’s IBIT Dominates Spot Bitcoin ETF Market Share
BlackRock’s iShares Bitcoin Trust, IBIT, remains the clear leader among U.S. spot Bitcoin ETFs.
IBIT started with around 22% of the market’s trading volume share at launch, when Grayscale’s converted GBTC fund still had an early advantage. Since then, BlackRock’s fund has grown its dominance significantly.
As of June 11, IBIT accounted for 73.7% of spot Bitcoin ETF trading volume.
BlackRock also leads by assets under management. U.S. spot Bitcoin ETFs now hold more than $76 billion in total AUM, with IBIT responsible for around $49 billion of that amount.
IBIT Became One of the Fastest-Growing ETFs Ever
IBIT has also set major records in the broader ETF market.
According to Bloomberg Senior ETF Analyst Eric Balchunas, IBIT became the fastest ETF to reach $70 billion in assets under management. The fund achieved the milestone in just 341 trading days.
That was five times faster than the previous record holder, SPDR Gold Shares, known as GLD, which took 1,691 trading days to pass $70 billion in AUM.
By comparison, spot Ethereum ETFs currently hold around $8.8 billion in combined assets under management.
Bitcoin ETF Outflows Increase During Bear Market
Despite the major trading volume milestone, U.S. spot Bitcoin ETFs are now facing pressure from growing investor withdrawals.
Since launch, the funds have recorded $53.9 billion in cumulative net inflows. BlackRock’s IBIT has been the strongest contributor, bringing in $62.2 billion in net inflows on its own.
However, the overall total has been reduced by more than $26.8 billion in net outflows from Grayscale’s higher-fee converted GBTC product.
The current bear market has also changed investor behavior. Since Bitcoin reached its all-time high near $126,000 on October 6, spot Bitcoin ETFs have seen $7.6 billion in net outflows. Year-to-date, the funds have recorded $3 billion in net outflows.
That includes a recent 13-day negative streak totaling $4.3 billion, one of the longest outflow periods since spot Bitcoin ETFs launched.
Ethereum ETFs Also See 2026 Outflows
Spot Ethereum ETFs have performed strongly since launch, with $11.2 billion in cumulative net inflows. BlackRock’s ETHA has led the category.
However, Ethereum ETFs have also come under pressure in 2026. They have recorded $1.1 billion in net outflows so far this year, including a 17-day outflow streak worth $900 million that ended on June 3.
This shows that the broader crypto ETF market is still closely tied to investor sentiment, Bitcoin price trends, and macro market conditions.
Bitcoin Price Drops Sharply From October High
Bitcoin traded at around $63,750 on Friday. The cryptocurrency was up 1% over the previous 24 hours but remained under heavy pressure over longer timeframes.
Bitcoin is down 21% over the past month, 27% year-to-date, and around 50% from its all-time high near $126,000 in October.
Bitwise Head of Research Europe André Dragosch said the recent sell-off was mainly driven by roughly $2 billion in weekly exchange-traded product net outflows. He estimated this was equal to around 50,000 BTC being effectively sold into the market over a short period.
BlackRock Prepares New Bitcoin Income ETF
BlackRock is also moving forward with another Bitcoin-related ETF product.
On Thursday, the asset manager filed a Form 8-A for its new iShares Bitcoin Premium Income ETF. The proposed fund aims to combine spot Bitcoin exposure with yield generation by actively selling call options on IBIT shares and Bitcoin ETP indices.
Bloomberg ETF analyst Eric Balchunas said the filing suggests the fund’s launch could be imminent.
Bitcoin ETFs Remain a Key Institutional Crypto Gateway
The upcoming $2 trillion cumulative trading volume milestone highlights how quickly U.S. spot Bitcoin ETFs have reshaped the crypto investment market.
Even with rising outflows and weaker Bitcoin price action, the products remain a major gateway for institutional Bitcoin exposure. BlackRock’s IBIT continues to dominate both trading volume and assets under management, while the wider spot Bitcoin ETF market remains far ahead of Ethereum, Solana, XRP, and Hyperliquid ETF products.
For investors, the next key question is whether Bitcoin ETF outflows will continue during the bear market or reverse if market sentiment improves.
