On May 13, 2026, Bloomberg senior ETF analyst Eric Balchunas shared a set of data on X that quickly ignited debate across the global asset allocation landscape. Since March of this year, BlackRock’s spot Bitcoin ETF—iShares Bitcoin Trust (IBIT)—has significantly outperformed the world’s largest gold ETF, SPDR Gold Shares (GLD), with IBIT leading by a remarkable 33 percentage points.
The divergence in capital flows is equally striking. During the same period, IBIT recorded a net inflow of roughly $4.2 billion, while GLD saw a net outflow of about $9 billion. Combined, this resulted in a capital flow gap of approximately $13 billion. This isn’t a routine sector rotation—it signals a structural shift in capital migration.
From Synchronized Gains to Divergence: Tracing the Timeline of This Rotation
To grasp the deeper significance of these numbers, we need to revisit the macro landscape of Q4 2025.
At that time, global central banks were expected to ease policy amid heightened geopolitical tensions, leading to a rare scenario where both gold and Bitcoin rallied in tandem. In December 2025, Bitcoin hit a historic high of about $126,000, while gold also surged within a strong upward channel. Both assets were driven by the same macro logic—a growing demand for alternatives to fiat currency credit systems.
In January 2026, market dynamics shifted dramatically. According to World Gold Council data, global gold ETFs saw a record monthly net inflow of around $19 billion, with assets under management (AUM) soaring to a historic peak of roughly $669 billion. Meanwhile, Bitcoin ETFs experienced net outflows that continued a multi-month trend. Escalating geopolitical conflict bolstered gold’s traditional safe haven narrative, while Bitcoin, having corrected sharply from its historic high, was increasingly categorized as a risk asset and subsequently reduced in portfolios.
The real turning point came in March. On March 4, GLD saw a single-day outflow of about $3 billion—the largest redemption in nearly two years. At the same time, Bitcoin ETFs ended four consecutive months of net outflows by mid-March, flipping to net inflows. U.S. spot Bitcoin ETFs attracted roughly $1.32 billion in net inflows for the month.
From March through May, the divergence accelerated. Bitcoin ETFs continued to post net inflows, with U.S. spot Bitcoin ETFs seeing about $2.44 billion in net inflows in April—the strongest monthly performance of 2026 so far. After global gold ETFs recorded a historic $12 billion net outflow in March, there was some recovery in April driven by Asian market demand, but North American institutional selling remained prominent.
Behind the 33 Percentage Points: Dissecting the Structural Divergence Between IBIT and GLD
As of May 14, 2026, Gate market data shows Bitcoin trading at approximately $79,116.7, down about 2.34% over 24 hours, up 11.76% in the past 30 days, and up 14.09% over the last 90 days. Its market cap stands at roughly $1.58 trillion, commanding a 57.17% market share.
IBIT, now the world’s largest spot Bitcoin ETF, managed assets totaling about $61.91 billion as of early May. While GLD’s AUM remains far larger, the directional difference in capital flows has become a crucial signal.
The table below summarizes the key milestones and data points of this rotation:
| Milestone | Bitcoin ETF Capital Flow | Gold ETF Capital Flow | Key Events |
|---|---|---|---|
| Q4 2025 | Inflows slowed | Continued net inflows | Bitcoin hits historic high near $126,000 |
| Jan 2026 | Overall net outflow | Global gold ETF net inflow of ~$19 billion | Gold ETF AUM reaches historic peak of ~$669 billion |
| Late Feb 2026 | Inflows turn positive | Outflows accelerate | Iran conflict escalates, capital begins to shift |
| Mar 4, 2026 | Sustained inflows | GLD single-day outflow of ~$3 billion | GLD sees largest single-day redemption in nearly two years |
| March 2026 | Net inflow of ~$1.32 billion | Global gold ETF net outflow of ~$12 billion | First positive monthly net inflow for Bitcoin ETFs in 2026 |
| April 2026 | Net inflow of ~$2.44 billion | Asian-driven recovery | IBIT accounts for over 70% of monthly inflows |
| May 2026 (mid-month) | Continued net inflows | Institutional demand remains weak | IBIT leads GLD by 33 percentage points |

Looking at asset growth trajectories, IBIT reached $70 billion in AUM in just 341 trading days, while GLD took 1,691 days to hit the same mark. This comparison isn’t about short-term capital battles—it highlights a fundamental difference in how institutions are adopting these assets within their allocation frameworks.
Replacement, Preservation, or Diversification: Three Narratives in the Asset Debate
There are three main narrative frameworks driving the current debate over this rotation, each with significant tension.
Narrative 1: Bitcoin is replacing gold as the preferred tool for "devaluation hedging"
A Nomura survey published in April 2026 found that nearly 80% of institutional investors plan to allocate 2% to 5% of their portfolios to cryptocurrencies. This data underscores a deepening recognition among institutions of crypto assets as strategic, long-term holdings.
Narrative 2: Gold remains a more reliable safe haven; Bitcoin’s "digital gold" story is still unproven
Not all institutions buy into the asset rotation thesis. Goldman Sachs recently maintained its year-end gold price forecast at $5,400 per ounce, citing strong central bank demand and lower long-term volatility compared to Bitcoin. Analysts noted that gold surged in 2025 while Bitcoin declined, suggesting that gold remains the safer choice in the current macro environment.
Narrative 3: This isn’t "replacement"—it’s "diversification." The two assets are moving toward distinct functional roles
This perspective argues that gold and Bitcoin aren’t locked in a zero-sum competition, but instead respond differently to the same macro variables. When markets lean toward risk aversion, gold tends to outperform; when liquidity is abundant and risk appetite rises, Bitcoin shows greater elasticity. BlackRock analysis points out that the correlation between gold and Bitcoin has dropped to just 0.10, indicating that their roles in portfolios are diverging rather than overlapping.
From Fringe to Mainstream: How This Rotation Is Reshaping the Crypto Industry
This capital rotation is structurally impacting the crypto industry on three levels.
First, Bitcoin ETFs are solidifying their status as a standalone asset class. As of early May 2026, total net assets in U.S. spot Bitcoin ETFs surpassed $100 billion. This scale has elevated Bitcoin ETFs from "niche alternative products" to standard components in institutional asset allocation. Nomura’s survey shows nearly 80% of institutional investors plan to allocate 2% to 5% of their portfolios to crypto assets over the next three years, suggesting the inflow potential is far from exhausted.
Second, asset allocation frameworks are undergoing generational change. The traditional "60/40" stock-bond model’s alternative asset exposure is evolving from gold-only to a dual structure of "gold + Bitcoin." IBIT reached the milestone that took GLD 1,691 days in just 341 trading days—a speed difference that not only reflects product demand, but also signals a paradigm shift in how a new generation of investors perceives store-of-value assets.
Third, the capital structure of the crypto market is being passively optimized. This rotation’s inflows are mainly entering through spot ETF channels, rather than on-chain leverage or derivatives. This means new positions are likely to have longer holding periods and lower risk tolerance. Compared to the leverage-driven volatility seen in the 2024–2025 cycle, today’s ETF-dominated inflows are more "allocation capital" than "trading capital." This provides a firmer price floor for Bitcoin, but also suggests short-term explosive moves may be less pronounced than in previous cycles.
Conclusion
$13 billion—the figure cited by Bloomberg ETF analyst Eric Balchunas—quantifies the capital flow gap between GLD and IBIT in this rotation. Its significance isn’t about declaring victory for one asset class, but rather marking a deeper shift: institutional investors are no longer framing decisions around "whether to buy Bitcoin," but are actively comparing and dynamically rebalancing between "allocating to gold or Bitcoin."
As of May 14, 2026, Bitcoin is quoted at about $79,116.7 on Gate, up roughly 14.09% over the past 90 days, with a market cap of $1.58 trillion. Gold prices have retreated from their historic highs above $5,600 seen from 2025 to early 2026. The trajectories of these two assets in Q2 2026 reveal a structural divergence—not short-term noise, but a signal that the landscape of store-of-value assets is being redrawn.
For market participants, the key question is no longer "Is Bitcoin digital gold?" but rather: In today’s macro environment, what proportion of your portfolio should be allocated to Bitcoin versus gold? The $13 billion shift may be just the opening chapter in a generational reallocation of assets.
