Key Findings
- Short-term arbitrage strategies drive over half of US Bitcoin ETF inflows, signaling weak long-term investor interest.
- Declining funding rates reduced arbitrage appeal, triggering $552 billion in ETF outflows.
- Just $17.5 billion (44%) of $38.6 billion inflows reflect genuine long-term Bitcoin holdings.
Arbitrage Strategies Dominate Bitcoin ETF Inflows
A 10x Research report indicates that 56% of Bitcoin ETF inflows stem from carry trades—buying spot Bitcoin via ETFs while shorting futures to exploit price gaps. Markus Thielen, Head of Research, notes:
"This suggests far weaker demand for Bitcoin as a long-term asset than media narratives imply."
Hedge funds and trading firms dominate holdings in ETFs like BlackRock’s IBIT, prioritizing yield spreads over directional exposure.

Why Arbitrage Appeal Is Fading
- Narrowing spreads: Declining funding rates slashed profitable opportunities.
- Position unwinding: Hedge funds exited non-viable trades, causing $552 billion in outflows.
- Market-neutral impact: ETF sell-offs were offset by futures purchases, stabilizing Bitcoin prices near $95,600.
Post-Election Shift Toward Long-Term Holdings
Since the 2025 US election, long-only Bitcoin buying has risen, though arbitrage still overshadows it. Institutional interest persists—Goldman Sachs increased iShares Bitcoin Trust holdings to $2.05 billion, calling it a "paradigm shift."
