It was a monumental first year for spot bitcoin ETFs—one that reshaped the investment landscape and accelerated mainstream adoption of digital assets.
Time flies when you’re breaking records. Believe it or not, it’s been one full year since the U.S. Securities and Exchange Commission (SEC) made its historic decision to approve spot bitcoin exchange-traded funds (ETFs) for listing in the United States.
On January 11, 2024, a new era in financial markets began as 11 spot bitcoin ETFs launched simultaneously. Flagship funds like the iShares Bitcoin Trust (IBIT) and the Fidelity Wise Origin Bitcoin Fund (FBTC) opened the door to direct, regulated exposure to bitcoin for millions of retail and institutional investors.
This approval marked the culmination of a long, tumultuous journey—one filled with rejections, lawsuits, and evolving regulatory perspectives. But once the floodgates opened, demand surged beyond expectations.

The Long Road to Approval
The story of spot bitcoin ETFs begins over a decade ago, with the Winklevoss Bitcoin Trust filing in 2013—when bitcoin traded for just $90.
That early attempt, like dozens that followed, was rejected by the SEC. Regulators cited concerns over market manipulation, investor protection, and the lack of robust surveillance mechanisms across cryptocurrency exchanges.
“Rules and surveillance to prevent manipulative techniques do not exist on all of the exchange venues where digital currencies trade,” said former SEC Chairman Jay Clayton in 2018, summarizing the agency’s long-standing resistance.
For years, the door remained firmly shut—until Gary Gensler took over as SEC Chair in 2021.
Gensler, a former MIT professor with deep knowledge of blockchain technology, signaled a shift. While still cautious, he acknowledged that certain crypto-based financial products could meet regulatory standards—if structured properly.
That openness led to the approval of bitcoin futures ETFs in October 2021, with the launch of funds like ProShares’ BITO. But while these were a step forward, they weren’t the real prize.
Investors and issuers wanted spot bitcoin ETFs—funds that hold actual bitcoin on the blockchain through secure custodians, offering direct ownership without expiration dates or roll costs.
Despite this demand, Gensler continued to resist—until a pivotal legal turning point changed everything.
The Legal Catalyst: Grayscale vs. the SEC
In June 2022, the SEC rejected Grayscale Investments’ application to convert its Grayscale Bitcoin Trust (GBTC) into a spot ETF. GBTC had operated for years as a private trust with limited liquidity and a premium/discount structure that frustrated investors.
Grayscale didn’t back down. The company sued the SEC—and won.
In August 2023, a U.S. appeals court ruled that the SEC’s denial was arbitrary and inconsistent, especially given its prior approval of futures-based ETFs. The court ordered the regulator to reconsider Grayscale’s application.
That decision created a domino effect. Rather than face more legal challenges, the SEC began approving other spot bitcoin ETF applications—including those from BlackRock, Fidelity, and Ark Invest.
By January 2024, the dam had broken.
Explosive Growth After Launch
When spot bitcoin ETFs finally launched on January 11, 2024, skeptics wondered: Was this too late?
Bitcoin was already trading near $46,000—up nearly 500x from its 2013 price—and many feared investors were buying at the peak.
They were wrong.
Over the next 12 months, bitcoin surged past $108,000**, more than doubling in value. By early 2025, it stabilized around **$94,000, driven in large part by relentless institutional demand funneled through ETFs.
Total inflows into spot bitcoin ETFs exceeded $37 billion** in their first year. Combined with price appreciation, this pushed total **assets under management (AUM)** to **$107 billion—a staggering milestone.
The standout performer? iShares Bitcoin Trust (IBIT).
Launched by BlackRock, IBIT attracted $38 billion** in net inflows and reached **$52.5 billion in AUM, becoming:
- The fastest ETF in history to hit $10 billion in assets
- The fastest to reach $50 billion
- A serious contender for the title of fastest ETF to $100 billion
The only record it missed? Reaching $1 billion in AUM. IBIT took four days—two days longer than BITO’s record-setting two-day sprint. But context matters: IBIT faced immediate competition from 10 other new entrants, while BITO had no rivals at launch.

GBTC’s Historic Outflows
One of the most dramatic storylines of the past year was the massive outflow from Grayscale Bitcoin Trust (GBTC).
Once the dominant vehicle for bitcoin exposure—with $28.5 billion in AUM built over 11 years—GBTC saw its fortunes reverse overnight.
Why?
- High fees: GBTC charged a 1.5% expense ratio, far above competitors like IBIT (0.12%) and FBTC (0% initially).
- Arbitrage unwinding: Many investors bought GBTC at a discount to net asset value (NAV), betting on an ETF conversion. Once approved, they exited for profits.
- Migration to lower-cost options: Investors flocked to cheaper, more efficient ETFs.
For 78 consecutive days, GBTC bled assets. By May 2024, it recorded its first daily inflow—but not before losing $17.5 billion**. Over the full year, outflows totaled **$21.5 billion.
Yet even with this hemorrhage, the broader spot bitcoin ETF ecosystem thrived—recording net inflows of $37.1 billion.
What’s Next? Future Milestones Ahead
With $107 billion in AUM, U.S.-listed spot bitcoin ETFs now represent nearly 6% of bitcoin’s total market capitalization—a significant footprint for just one year.
And momentum shows no signs of slowing.
In the first week of 2025 alone, investors poured another $1.7 billion into these funds.
Looking ahead, IBIT and others are poised to achieve new milestones:
- First ETF to $100 billion in AUM—a title currently held by bond and equity giants.
- Surpassing the SPDR Gold Trust (GLD), which manages around $75 billion—proving digital assets can rival traditional safe-haven investments.
- Expanding globally, as other regulators observe U.S. success and consider their own approvals.
