Bitcoin is trading near USD 86,000 ahead of a major derivatives event that could reshape short-term market conditions. Nearly USD 16 billion in Bitcoin options will expire on Deribit on September 25. Meanwhile, wallets holding 100 to 1,000 BTC continue adding coins as traders watch key strike levels.
The expiry matters because options positioning can influence Bitcoin’s price behavior before contracts settle. Market makers regularly buy or sell the cryptocurrency and related instruments to balance their exposure as prices change.
Those hedging flows can absorb part of a market move under certain positioning conditions. As a result, realized volatility may stay lower ahead of a large expiry, even while substantial exposure remains open.
Wallets holding between 100 and 1,000 BTC have accumulated 113,950 Bitcoin since July 15, according to Santiment. Their combined holdings have increased 2.22% to 5.24 million BTC.
The accumulation continued while Bitcoin recovered and briefly touched USD 87,000 earlier this week. The cryptocurrency later retraced and stabilized near USD 84,000 before moving around USD 86,000. Santiment has monitored this wallet group for five years. Its historical data shows that periods of strong accumulation have often occurred before or alongside stronger Bitcoin price moves.
The latest buying therefore shows that larger holders continued accumulating during the recovery. It also means the recent price move has not relied only on retail participation. Still, the source of the broader recovery remains important. Trace Finance co-founder Bernardo Brites said the pace of the rebound partly reflected a short squeeze.
Brites said the larger question concerns where fresh capital is entering the market. He also cautioned against treating the move as evidence of a broad return in risk appetite.
Nearly USD 16 billion in Bitcoin options open interest will expire on September 25. Calls account for approximately USD 9.6 billion, while puts represent about USD 6.4 billion. A notable amount of call open interest sits near the USD 90,000 and USD 100,000 strike prices. Those levels therefore contain substantial options positioning as the expiry approaches.
Still, call open interest does not automatically represent a direct bet on higher Bitcoin prices. Traders also use calls within spreads, hedging strategies, and market-making positions.
Instead, the data identifies areas where derivatives exposure has accumulated. As Bitcoin moves toward major strikes, changes in option values can require market makers to adjust their hedges.
This process can involve buying or selling Bitcoin and related instruments. The size and direction of those adjustments depend on how market makers hold and hedge their exposure. Therefore, price behavior before the expiry may partly reflect derivatives mechanics rather than only changes in demand for Bitcoin itself.

Bitcoin's recent stability does not necessarily mean the underlying market has become less volatile. Options positioning can influence how strongly prices react before contracts expire.
Market makers continuously adjust their exposure as Bitcoin moves. Depending on their positioning, those transactions can absorb some buying or selling pressure and reduce realized price swings.
The structure changes once the September 25 contracts expire. Some positions disappear, while others may move into contracts with later expiration dates. As this exposure resets, the hedging activity linked to the expiring contracts can also decline. Bitcoin may then respond differently to a new wave of spot buying or selling.
Brites also connected Bitcoin's recent strength with a wider macro backdrop. He pointed to a rate hike, oil near USD 100, and elevated yields during the rally. He said some investors may view Bitcoin as a hedge against inflation, fiscal pressure, and geopolitical risk rather than a simple bet on easier monetary conditions.
This distinction adds another element to the market structure surrounding the expiry. Bitcoin enters September 25 with large options exposure, continued whale accumulation, and sizeable positioning around USD 90,000 and USD 100,000.
Bitcoin enters the September 25 expiry with nearly USD 16 billion in options exposure and sustained buying from 100-to-1,000-BTC wallets. The expiry could alter market-maker hedging flows, while accumulation and macro-driven demand remain important factors for traders tracking the next price move.
