Bitcoin Grinds Higher Past $64K as IBIT Call Positioning Concentrates at $38 Strike; XRP Funding Leads Majors

Bitcoin traded at $64,742 midday Thursday, up 1.17% over 24 hours, as IBIT options positioning showed call-heavy skew with a P/C open interest ratio of 0.676 and heavy call open interest stacked at the $38 and $40 strikes. The tilt sits alongside the tightest funding print among majors on ETH at just +2.18% annualized, pointing to selective conviction rather than broad-based positioning.

Market Pulse

Majors traded green across the board with modest intraday ranges. Bitcoin held $64,742 on a 1.89% session range, ether printed $1,919.50 (+0.44%), solana $74.67 (+1.32%), and XRP $1.092 (+1.67%). Funding rates on Binance perpetuals ran positive but uneven: XRP annualized at +10.95%, BTC at +9.89%, SOL at +6.30%, and ETH lagging at +2.18%. The ETH funding softness alongside its narrower 24-hour gain suggests less speculative leverage rebuilding on that leg of the trade.

Options Positioning

IBIT (underlying $36.17) shows the cleanest institutional read: P/C open interest of 0.676, IV30d at 36.7%, with top call OI concentrated at the $38 strike (59,796 contracts) and $40 strike (58,562). Put OI clusters at $35 and $30, consistent with delta hedging rather than defensive positioning. FBTC skews further call-heavy at 0.485 P/C OI, though its top put strike at $40 carries 16,819 contracts of OI — a structural floor bid worth flagging.

On the ether side, ETHA runs a heavier 0.832 P/C OI ratio with elevated IV at 51.1%, and top put OI at the $16 strike (50,312 contracts) sits directly at call OI's mirror — a classic pinning setup into expiry. ETHE stays call-dominated (0.155 P/C OI). BSOL and XRPC volumes remain thin, with XRPC's 0.017 P/C OI ratio pointing to almost purely directional call exposure.

Narrative

The tape is running without a single dominant catalyst. Wire coverage flagged Citadel positioning for a surprise Fed rate hike against a market pricing a hold — a divergence that could explain the muted ETH funding versus firmer BTC and XRP bids. Separately, InflowScan data shows BlackRock registered an $89.83 million reversal in bitcoin exposure per morning reporting, adding texture to yesterday's settled flow print. Ethereum-specific commentary remained cautious, with analysts flagging fading bullish momentum despite the asset holding key support.

Afternoon Watch

Stablecoin supply contracted overnight — USDT down $627.7M and USDC down $346.9M per InflowScan data. A continued drawdown into the afternoon would historically be associated with dry-powder deployment rather than fresh sidelining.
IBIT $38 call OI concentration into month-end: any close near that strike this week would put dealer gamma dynamics in focus.
Fed speaker calendar and any incremental commentary following the Citadel rate-hike positioning story — the divergence between hedge-fund positioning and market pricing is the session's underlying tension.
