Bitcoin Slips Below $66K at Midday as IBIT Options Show Long-Dated Call Skew; ETH Funding Runs Hottest

Bitcoin traded at $66,040 by midday Wednesday, off 0.8% over 24 hours, while options positioning in BlackRock's IBIT showed a call-heavy volume tilt (P/C 0.54) anchored by a $140-strike open interest wall of nearly 55,000 contracts — roughly 3.7x the underlying's current $37.69 print. The configuration points to persistent long-dated upside positioning even as spot drifts lower.

Market Pulse

Spot majors are mixed with a soft bitcoin bid. BTC prints $66,040 (-0.78% ↑... correction: -0.78% ↓) on a 1.30% intraday range. ETH holds $1,942.63 (+0.63% ↑) with a wider 2.16% range, keeping the $2,000 handle in view. SOL at $78.46 and XRP at $1.1512 are green fractionally on similar ~2.3% ranges.

Binance perpetual funding tilts modestly long across the complex but with a clear ETH skew: BTC prints +0.0014% per 8h (~+1.6% annualized), while ETH runs at +0.0065% per 8h (~+7.1% annualized) — the hottest reading in the majors. SOL sits at ~+4.3% annualized; XRP is effectively flat. The pattern is consistent with directional longs concentrated in ETH rather than a broad leverage build.

Options Positioning

IBIT (underlying $37.69) shows a session P/C volume ratio of 0.54 against a P/C open-interest ratio of 0.70 — call-leaning intraday flow on a more balanced legacy book. The largest single call-strike concentration sits at $140 (54,819 contracts OI), with additional stacking at $40 and $45. Put OI clusters near $25-$30, framing a wide asymmetric distribution.

FBTC (underlying $57.83) reads more emphatically call-tilted, with P/C volume at 0.21 and top call OI at the near-money $57.5 strike (11,502 contracts). ETHA (underlying $14.57) prints P/C volume of 0.37 and 30-day IV of 49.9% — the elevated IV consistent with the funding-rate signal above. Top ETHA call OI concentrates at $16 (28,383 contracts), just above spot. XRPC stands out for near-zero put interest (P/C OI 0.018) and a 69.7% IV — thin, one-sided book.

Narrative

Wire coverage is dominated by two structural threads. First, stablecoin-market strain: reports of a Balance stablecoin collapse tied to a drained bitcoin vault, alongside broader reserve-model comparisons among 2026 issuers, are keeping counterparty focus on collateral quality. Second, a Benzinga read on the CLARITY Act notes Trump-side acceptance of ethics guardrails, though the piece flags the framework as insufficient without further legislative build-out.

Also circulating: another crypto treasury company signaling BTC sales, and a Benzinga note on MSTR, BMNR and BSTR trading weakness tied to bitcoin's drawdown from prior highs. Nothing in the tape looks like a single-catalyst driver — the softness reads as position-management ahead of afternoon prints rather than headline reaction.

Afternoon Watch

Stablecoin supply drift into the close — USDT market cap has bled $78M over 24 hours to $184.1B, while USDC added $36M to $73.4B, per InflowScan data. A continuation of USDT contraction alongside USDC growth has historically been associated with a rotation in dollar-liquidity venue, not a net dry-powder change.
ETH funding refresh at the next 8-hour print — a sustained reading above +7% annualized would be consistent with prior episodes of ETH-led leverage buildup.
