US spot Bitcoin ETFs recorded eight consecutive days of net inflows last week, pulling in approximately $2.39 billion — the largest weekly total since October 2025, according to fund flow data. The inflow streak has pushed cumulative net inflows since the products' January 2024 launch to roughly $57.5 billion, with total assets across the category approaching $108 billion.

BlackRock's iShares Bitcoin Trust (IBIT) and Fidelity's FBTC have absorbed the bulk of the new capital. The sustained pattern marks a reversal from earlier stretches in 2026, when the ETF complex experienced repeated net outflows. Eight straight sessions of positive flows point to a durable shift in positioning rather than a single large allocation moving the total.

The price of Bitcoin itself has not followed. The asset trades in the $83,000 to $84,000 range, roughly 34% below its October 2025 peak near $126,000. That divergence between institutional inflows and spot performance frames the current market structure: capital is entering the asset class at the fastest weekly pace in months while the price remains rangebound.

Options positioning compounds the disconnect

Derivatives markets tell a more aggressive story than spot. Open interest in IBIT options has expanded significantly since late 2024, and recent activity shows heavy concentration at $90,000 and $95,000 call strikes. Traders are effectively treating the current price zone as a floor rather than a ceiling.

That clustering has mechanical consequences. When large volumes of options settle around specific strikes, market makers hedge their exposure by trading the underlying asset, and those hedges tend to pull prices toward the strikes — a dynamic known as gamma pinning. The current buildup between $85,000 and $90,000 appears to be contributing to Bitcoin's reluctance to break out of its range in either direction.

There is a recent precedent. In December 2025, a record $24 billion notional options expiry produced similar pinning dynamics: the sheer weight of outstanding contracts compressed volatility and limited directional movement until the expiry cleared. The present configuration is a smaller version of the same effect.

Patient capital versus leveraged flow

The gap between the flow data and the price chart partly reflects who is buying. ETF purchasers are not the same cohort as leveraged spot traders. Many institutional allocations are strategic, long-duration positions that do not chase short-term price action — capital that accumulates on weakness rather than buying breakouts. Nearly $60 billion in cumulative net inflows and $108 billion in total assets indicate deepening institutional footing, even as spot sits more than a third below its high.

The operational takeaway for desks is that flow data and price action are currently transmitting different signals, and the derivatives market is the mechanism reconciling them. Until the concentrated call positions resolve, hedging pressure will likely continue to contain realized volatility.

The next major options expiry cycle is the key date to watch. If the $90,000-plus calls expire worthless, market makers will unwind their hedges, potentially freeing price movement in either direction. If Bitcoin pushes into the $85,000 to $90,000 zone before those expirations, the same hedging dynamics could accelerate the move as dealers buy the underlying to stay neutral.
