The debut of spot bitcoin ETFs in the U.S. marked a watershed moment for the digital asset industry, with early data revealing strong investor interest and significant capital movement. On their first trading day, Bitwise’s BITB and Fidelity’s FBTC led the pack in inflows, while Grayscale’s GBTC experienced a relatively modest outflow—far less than many had feared. BlackRock’s IBIT also attracted solid demand, though initial figures may not yet reflect its full momentum.
Record-Breaking First-Day Activity
According to preliminary data compiled by BitMEX Research and cited by Bloomberg, Bitwise’s bitcoin ETF (BITB) saw the largest net inflow on day one, bringing in $238 million** in net assets. Fidelity’s FBTC followed closely behind with **$227 million in inflows, signaling strong retail and institutional appetite for competitively priced, transparent spot bitcoin exposure.
BlackRock’s iShares Bitcoin Trust (IBIT), despite expectations of dominating early trading due to the firm’s massive asset management footprint, recorded $110 million in inflows—ranking third among the new entrants. However, experts caution that these figures may be incomplete.
Eric Balchunas, ETF analyst at Bloomberg Intelligence, noted on social media that many issuers released only preliminary data ahead of Friday’s market open, with final numbers potentially delayed until later in the week. He suggested that some of IBIT’s Thursday inflows might not appear until Friday’s reporting cycle, meaning BlackRock could see upward revisions.
Grayscale’s GBTC Outflows Milder Than Expected
Grayscale’s Bitcoin Trust (GBTC), which transitioned from a closed-end fund to an open-ended ETF on January 11, faced intense scrutiny ahead of its conversion. Analysts widely predicted massive outflows as investors gained the ability to redeem shares for underlying BTC for the first time.
Instead, GBTC saw just $95 million in outflows on day one—a surprisingly restrained figure given its pre-ETF premium and the expectation of arbitrage-driven selling pressure. This suggests that while some investors took profits or shifted capital to lower-fee spot ETFs, a substantial base of long-term holders remained committed.
James Butterfill, head of research at CoinShares, commented that the full picture of capital flows may not be clear until early the following week, as settlement processes and reporting lags affect real-time data accuracy.
“Total net flow for the day into the new ETFs was $625.8 million. Bitwise was the victor for day one.”

Historic Trading Volume Signals Market Maturation
Beyond inflows and outflows, trading volume underscored the historic nature of the launch. Spot bitcoin ETFs collectively generated $4.6 billion in trading volume on their debut day, according to Bloomberg Intelligence analyst James Seyffart.
Grayscale’s GBTC and BlackRock’s IBIT led in trading activity, reflecting both brand recognition and high investor engagement. Eric Balchunas called it “easily the biggest Day One splash in ETF history,” surpassing even major traditional fund launches.
For context, ProShares’ bitcoin futures ETF (BITO), which launched in October 2021 near the peak of the crypto bull market, recorded $1 billion in trading volume and $570 million in inflows on its first day. While BITO remains active, recent data from K33 Research shows it experienced outflows of approximately 3,000 BTC (~$140 million) just before the spot ETF launch—likely as investors rotated into more efficient spot-based alternatives.
Why Spot Bitcoin ETFs Matter
Spot bitcoin ETFs represent a transformative shift in how mainstream investors access cryptocurrency. Unlike futures-based ETFs, which track bitcoin futures contracts and carry roll costs, spot ETFs hold actual bitcoin on their balance sheets. This direct exposure appeals to long-term investors seeking simplicity, transparency, and lower tracking error.
Their approval by the SEC after years of hesitation signals growing regulatory acceptance of digital assets as legitimate investment vehicles. These products allow investors to gain exposure to BTC, the largest and oldest cryptocurrency, through conventional brokerage accounts—no wallets, private keys, or exchanges required.
Standard Chartered analysts project that spot bitcoin ETFs could attract $50 billion to $100 billion in inflows throughout 2025 alone, driven by institutional adoption and increasing retail participation.

Frequently Asked Questions
What is a spot bitcoin ETF?
A spot bitcoin ETF is an exchange-traded fund that directly holds physical bitcoin (BTC) rather than futures contracts. It allows investors to gain exposure to bitcoin's price movements through traditional brokerage platforms without needing to buy or store crypto directly.
Why did Grayscale’s GBTC only lose $95 million?
Despite fears of massive redemptions after GBTC became an ETF, outflows were limited due to a combination of long-term holder loyalty, tax implications of selling, and gradual market absorption of sell pressure. Many investors may prefer holding over redeeming at this stage.
Which bitcoin ETF had the highest first-day inflow?
Bitwise’s BITB led with $238 million in net inflows on day one, followed by Fidelity’s FBTC with $227 million. Both outpaced BlackRock’s IBIT, which reported $110 million—though delayed reporting may adjust this figure upward.
Do spot bitcoin ETFs hold real bitcoin?
Yes. Unlike futures-based ETFs like BITO, spot bitcoin ETFs purchase and securely store actual BTC on behalf of shareholders. This direct ownership model enhances transparency and reduces counterparty risk.
How much trading volume did bitcoin ETFs generate on debut?
Collectively, spot bitcoin ETFs achieved $4.6 billion in trading volume on their first day—a record for any new class of ETFs—and signaling strong market confidence and liquidity.
Are more bitcoin ETFs expected in 2025?
While nine spot bitcoin ETFs launched simultaneously in January 2025—including those from Valkyrie, Ark Invest, and VanEck—the current lineup is expected to remain stable unless new applications are approved. Competition will likely focus on fee reductions and marketing.
