Billionaire hedge fund managers are quietly rotating out of one of Wall Street’s most beloved growth stories and into a niche BlackRock vehicle tied to Bitcoin. The shift pits the steady, cash‑gushing power of Amazon against a speculative bet that a single exchange‑traded fund could ultimately climb as much as 13,500%, according to some of the most aggressive forecasts in the market. I want to unpack what is actually changing in these portfolios, why the numbers behind both sides of the trade matter, and how realistic that kind of upside really looks.
At the center of the move is a simple but dramatic trade: sell Amazon, buy a BlackRock ETF that holds Bitcoin. On one side is a company that Wall Street expects to grow earnings at a brisk but comprehensible pace, and on the other is a structure whose potential returns depend on a volatile digital asset and a long runway of institutional adoption. The contrast between those profiles tells investors a lot about how some of the richest market participants are thinking about risk, reward, and the next decade of returns.
Why billionaire hedge funds are trimming Amazon
The first part of the story is not that Amazon has suddenly become a bad business, but that some billionaire managers see better risk‑reward elsewhere. In the third quarter, reporting shows that In the period, hedge fund billionaires Philippe Laffont and Steven Schonfeld sold Amazon stock and added to other positions, signaling a willingness to reduce exposure even to a dominant platform company. Philippe Laffont and Steven Schonfeld are not momentum chasers; they are known for concentrated, research‑heavy bets, so when they lighten up on a core name like Amazon it suggests a deliberate reallocation rather than a short‑term trade.
That reallocation has now extended into a more specific pivot away from Amazon and toward a BlackRock vehicle tied to Bitcoin. Separate disclosures show that in the third quarter, two hedge fund billionaires sold Amazon, listed on NASDAQ under the ticker AMZN, and increased their holdings in the iShares Bitcoin Trust, a move detailed in coverage that notes how such managers can be useful sources of inspiration for other investors. The fact that these billionaires are willing to swap a stake in Amazon for more exposure to a Bitcoin Trust signals a belief that the upside in digital assets, accessed through a BlackRock ETF wrapper, outweighs the relatively more predictable growth of a Big Tech staple.
Amazon’s growth story is still powerful
None of this means the underlying Amazon thesis has collapsed. Wall Street still expects the company to deliver robust profit expansion as it leans on cloud computing, advertising, and logistics scale. Analysts project that Amazon’s earnings will increase at 19% annually over the next three years, a pace that would be enviable for almost any large‑cap stock and that supports the idea of continued compounding for patient shareholders. Those expectations, laid out in detail by Wall Street research, underscore that the recent selling is about relative opportunity, not a collapse in fundamentals.
From my perspective, a 19% earnings growth trajectory for a company of Amazon’s size is exactly the kind of profile that long‑term institutional investors usually prize. It offers a blend of scale, diversification across e‑commerce and cloud, and a track record of reinvestment that has already reshaped industries from retail to streaming. When billionaire managers walk away from that in favor of a far more volatile asset, they are effectively saying that even strong compounding is not enough if they believe another vehicle can deliver orders of magnitude more upside. That is a high bar, and it sets the stage for why the BlackRock ETF has captured their attention.
The BlackRock Bitcoin ETF and the 13,500% claim
The ETF at the center of this rotation is the iShares Bitcoin Trust, a BlackRock product that gives investors exposure to Bitcoin through a regulated, exchange‑traded structure. For hedge fund managers who want crypto exposure without dealing directly with wallets or exchanges, it is a clean way to plug digital assets into a traditional portfolio. According to reporting on the third‑quarter moves, two billionaire managers sold Amazon and added to positions in this iShares Bitcoin Trust, effectively using a mainstream ETF to express a high‑conviction view on Bitcoin’s long‑term trajectory through a BlackRock vehicle.
The eye‑catching part of the story is not just that billionaires are buying a Bitcoin ETF, but the magnitude of the upside some analysts are willing to entertain. Several Wall Street analysts expect the market value of Bitcoin to eventually reach $50 trillion, implying more than 13,500% upside from recent levels if those projections prove accurate. I see that figure as a theoretical ceiling rather than a base case, but it explains why an ETF that simply tracks Bitcoin can be framed as a vehicle with venture‑style return potential, especially when compared with a mature giant like Amazon.
Tom Lee’s 3,000% Bitcoin thesis and what it implies
Within that spectrum of bullish views, Tom Lee at Fundstrat Global Advisors has become one of the most cited voices. Tom Lee at Fundstrat Global Advisors argues that Bitcoin’s price could hit $3 trillion in the long run, which implies more than 3,000% upside for the cryptocurrency itself. If Bitcoin were to climb that far, the iShares Bitcoin Trust and similar ETFs would likely see their net asset values rise in tandem, turning today’s allocations into potentially transformational wins for early institutional buyers.
From my vantage point, the Tom Lee framework helps explain why a 3,000% scenario and a 13,500% scenario can coexist in the same conversation. The lower figure can be seen as a more conservative, though still extremely optimistic, path based on increased adoption, while the higher number reflects a world in which Bitcoin captures a much larger share of global wealth. For billionaire hedge fund managers, even a fraction of that upside can justify reallocating capital from a company like Amazon into a BlackRock ETF that tracks Bitcoin, especially if they believe the downside is cushioned by growing mainstream acceptance of digital assets.
How everyday investors should read the billionaire pivot
Watching billionaires sell Amazon and buy a Bitcoin ETF can be both tempting and misleading for individual investors. On one hand, these managers have access to research, risk models, and trading infrastructure that most people do not, and their willingness to move into the iShares Bitcoin Trust signals real conviction about the asset class. On the other hand, their portfolios can absorb far more volatility than a typical retirement account, and they can change course quickly if the thesis breaks, something smaller investors often struggle to do.
For me, the key takeaway is not that everyone should dump Amazon and chase a potential 13,500% gain, but that the market is entering a phase where even established growth stocks are being weighed against highly speculative alternatives. Amazon still has a credible 19% earnings growth outlook, backed by its scale and diversified revenue streams, while the BlackRock ETF tied to Bitcoin offers a lottery‑ticket style payoff that depends on scenarios laid out by analysts like Tom Lee and others who see multi‑thousand‑percent upside. The rational response is to treat these billionaire moves as one input among many, stress‑test your own risk tolerance, and remember that what makes sense for Philippe Laffont and Steven Schonfeld in a multi‑billion‑dollar fund may not be appropriate for a smaller, more conservative portfolio.
There is also a psychological dimension that I think is easy to overlook. When high‑profile managers rotate into something as volatile as Bitcoin through a BlackRock ETF, it can create a sense of urgency or fear of missing out among less experienced investors. Yet the same disclosures that highlight their enthusiasm for the iShares Bitcoin Trust also show that they are willing to exit even beloved names like Amazon when the numbers no longer fit their models. That discipline, not the specific trade, is the part of the billionaire playbook that is most worth emulating.
