“They Are Not Long Bitcoin”
Hayes factors to the ETF’s largest holders, hedge funds and financial institution buying and selling desks, together with companies like Goldman Sachs, and argues they’re primarily engaged in what’s referred to as a foundation commerce.
Right here’s the way it works:
- Funds purchase IBIT ETF shares
- Concurrently quick CME Bitcoin futures
- Seize the yield distinction between the ETF and futures (the premise)
- Use the ETF shares as collateral for the futures quick
In response to Hayes:
“They are not long Bitcoin. They only play in our sandbox for a few extra points over Fed Funds.”
This has develop into much more widespread in 2025 as US charges have fallen, with the Federal Reserve chopping charges 3 times this 12 months, decreasing yields throughout conventional markets and making arbitrage alternatives extra engaging.

Why ETF Inflows Can Be Deceptive
When the premise is excessive sufficient, hedge funds rush into the commerce, creating the looks of enormous institutional inflows.
When the premise compresses, because it has a number of instances all through 2025, those self same establishments unwind the commerce, inflicting sharp ETF outflows.
Hayes says this dynamic creates a harmful phantasm, and it performs out like this:
When the premise spikes → ETF inflows surge → “Institutions are buying Bitcoin!”

What Modified in 2025
Earlier this 12 months, Bitcoin rose steadily whilst greenback liquidity tightened underneath the incoming Trump administration and US Treasury issuance surged. ETF inflows and shopping for from digital asset trusts helped offset the liquidity drag.
However Hayes argues that that section could also be over.
- A number of digital asset trusts (DATs) have traded under NAV this autumn.
- The ETF foundation commerce has develop into much less engaging as futures spreads narrowed.
- Hedge funds have decreased their positions, triggering noticeable outflows throughout the ETF advanced for weeks at a time.
With these synthetic demand drivers fading, Hayes says Bitcoin lastly has to answer the underlying macro atmosphere once more.

“Bitcoin Must Fall” — Hayes on Quick-Time period Strain
In response to Hayes:
“Bitcoin must fall to reflect the current short-term worry that dollar liquidity will contract or not grow as fast as the politicians promised.”
In different phrases:
ETF flows pushed Bitcoin up when liquidity didn’t justify it.
Now these flows are gone, and liquidity nonetheless issues. His message for late 2025 is blunt:
- Most ETF inflows had been arbitrage, not long-term institutional perception.
- BlackRock’s greatest ‘holders’ aren’t lengthy Bitcoin, they’re lengthy the premise.
- The unwind of these trades is now affecting Bitcoin’s value.
For retail buyers, the lesson is easy:
ETF flows let you know extra in regards to the futures curve than institutional conviction.
