U.S. spot Bitcoin exchange-traded funds recorded $457 million in net inflows in a single day, marking their strongest daily performance since mid-November, according to data from SoSoValue.
The move highlights renewed institutional engagement with Bitcoin through regulated investment vehicles, even as derivatives markets reflect a more defensive stance.
Fidelity’s FBTC led the inflows with $391 million, while BlackRock’s IBIT added $111 million. Total assets held across U.S. spot Bitcoin ETFs have now surpassed $112 billion, accounting for approximately 6.5% of Bitcoin’s total market capitalization, with cumulative net inflows exceeding $57 billion.

Despite the strong inflows, not all funds participated equally. ARK 21Shares’ ARKB and Bitwise’s BITB posted modest outflows, underscoring selective positioning rather than broad-based accumulation across all ETF products.
Derivatives Signal Caution Ahead of Record Options Expiry
However, signals from the derivatives market suggest a more cautious near-term outlook. According to Glassnode, Bitcoin is approaching its largest-ever options expiry while spot prices remain range-bound.
Options market data suggests cooling participation and reduced bullish conviction, with lighter trading volumes and continued demand for downside protection.
At-the-money implied volatility now sits near 44%, down more than 10 volatility points from recent highs, suggesting the market is pricing in more contained price action.
Meanwhile, options skew remains firmly in put territory, signaling that downside risk continues to be priced more aggressively than upside exposure.
Glassnode also notes that dealer positioning has turned long gamma into year-end, a dynamic that can mechanically suppress spot price volatility as hedging flows dampen directional moves. This environment has favored carry trades, with volatility sellers benefiting as implied volatility compresses following the latest Federal Open Market Committee meeting.
On-chain data adds another layer of complexity. A significant portion of Bitcoin supply remains held below acquisition cost, pointing to pockets of fragility in spot demand. From a technical perspective, analysts identify resistance between $93,000 and $120,000, with structural support forming near $81,000.
Why This Matters
Strong ETF inflows show institutions are building Bitcoin exposure, but cautious positioning in options markets suggests traders remain wary of near-term price moves as the market approaches a key volatility reset.

A Bitcoin spot ETF (exchange-traded fund) allows investors to gain exposure to Bitcoin without holding the cryptocurrency directly. The ETF tracks the spot price of Bitcoin, providing a regulated and convenient way for institutions and retail investors to invest.
When money flows into Bitcoin ETFs, it increases demand for Bitcoin, which can put upward pressure on the price. Large inflows, like $457M in one day, indicate strong institutional interest.
An options expiry is the date when options contracts (rights to buy or sell Bitcoin at a set price) must be settled. Large expiries can affect Bitcoin’s price, as traders adjust positions, hedge risks, and rebalance portfolios.
Put skew occurs when puts (options to sell) are priced higher than calls (options to buy). It indicates that the market is pricing in more downside risk than upside potential, showing cautious sentiment.
