Sygnum CIO Fabian Dori is pushing back on the dominant narrative around recent bitcoin ETF outflows, arguing that on-chain and market data do not support the theory that investors are selling BTC to raise cash for anticipated IPOs like SpaceX and Anthropic. Bitcoin's selling pressure drove the asset to a 2026 low below $60,000 in early June, more than 50% off its all-time high of nearly $125,000 set last October.

Why it matters

If the IPO-rotation thesis were correct, exchange balances would show unusual outflow patterns and stablecoin market capitalisation would likely contract as capital left the crypto ecosystem. Neither is happening, Dori says. Exchange flows remain broadly normal, stablecoin supply shows little meaningful contraction, and higher-risk crypto products are still attracting inflows — all inconsistent with a broad exit from digital assets.

The strongest counter-evidence, Dori argues, comes from derivatives. CME bitcoin futures open interest has declined in tandem with ETF redemptions, a relationship that points toward the unwinding of cash-and-carry arbitrage positions rather than equity reallocation. In a cash-and-carry trade, institutions buy spot BTC — often via an ETF — while simultaneously shorting BTC futures to capture the premium. When that premium narrows or funding rates deteriorate, traders unwind by selling spot and closing futures shorts, generating ETF outflows that look bearish but are mechanically neutral.

Market impact

"Open interest and funding rates moved very positively together over the same period," Dori told CoinDesk.

Frequently asked questions

  1. What is a cash-and-carry arbitrage trade in bitcoin ETFs?

    Institutions buy spot BTC through an ETF while shorting BTC futures to capture the premium between the two prices. When that premium narrows, they unwind both legs simultaneously — selling the ETF and closing the futures short — which produces outflows that are mechanical rather than directionally bearish.

  2. Why does CME open interest declining alongside ETF outflows matter?

    The parallel drop in CME bitcoin futures open interest and ETF redemptions is Dori's key evidence: if investors were rotating into IPOs, futures positioning would not necessarily fall in tandem. The correlation instead points to coordinated unwinds of paired spot-futures arbitrage positions.

  3. How low did bitcoin fall in 2026 and what drove the sell-off narrative?

    Bitcoin dropped below $60,000 in early June 2026, its lowest level of the year and more than 50% below its all-time high of nearly $125,000 set in October 2025. The dominant narrative attributed the decline to investors selling BTC to raise cash for anticipated IPOs including SpaceX and Anthropic.
