IBIT Volume Skews Call-Heavy as BTC Drifts at $77,259; ETHA Implied Vol Holds Near 50%

Institutional options flow tilted call-heavy on BlackRock's IBIT through Thursday's morning session, with a 0.63 put/call volume ratio and the $50 strike commanding 81,487 contracts in open interest. The positioning skew arrived as Bitcoin drifted to $77,259, down 0.3% on the day, with funding rates across the majors holding modestly positive.

Market Pulse

Bitcoin trades at $77,259, off 0.3% over 24 hours with a 1.88% intraday range. Ether holds $2,134 (+0.2%), Solana $86.51 (+0.4%), and XRP $1.36 (-0.3%), with XRP testing the $1.35 handle that traders have flagged as near-term support. Funding-rate tilt is mildly long on the majors: Binance perpetual funding annualizes to roughly +7.4% on BTC and +5.6% on ETH. SOL and XRP funding sit fractionally negative — consistent with light short bias rather than aggressive positioning. No single asset has cleared its intraday range top, leaving the tape in low-conviction drift.

Options Positioning

The IBIT chain skews unambiguously call-heavy: P/C volume of 0.634 and P/C open interest of 0.718, with the $50 call commanding 81,487 contracts of OI versus 61,818 at the $35 put. FBTC reinforces the same upside lean — P/C volume at 0.107 and the $100 call strike sitting at 10,061 OI. ETHA tells a different story: P/C volume above parity at 1.056 against IV30d of 49.7%, with put OI clustered at $10 and $5 — structurally hedged rather than directional. ETHE's 1.165 P/C volume echoes that defensive ETH posture. BSOL shows the highest P/C volume reading at 1.302, though active contracts are thin at 116.

Narrative

Headline flow is light. Avalanche's tie-up with a Korean QR payment network for stablecoin rails is the morning's most concrete institutional-adjacent print, though it has yet to move AVAX materially. Ripple's CLO weighing in on the CLARITY Act amid Trump veto chatter keeps regulatory risk on the radar for XRP, which is testing $1.35 with $488M in open interest stacked nearby per market commentary. Cardano-related items — Hoskinson targeting Bitcoin DeFi and an internal IO Research governance rift — point to project-specific noise rather than sector beta. Stablecoin supply offers little fuel: USDC added $30M over 24 hours, USDT essentially flat at +$0.2M, suggesting dry powder is parked, not staging.

Afternoon Watch

IBIT call OI concentration at the $50 strike — sustained dealer hedging flows have historically been associated with pinning behavior into expiry.
XRP's $1.35 level — the asset is sitting on it, with options chain (XRPC P/C OI 0.040) showing minimal downside hedging.
ETHA IV30d near 50% versus IBIT at 36.6% — the vol spread suggests the market is pricing ETH as the higher-beta leg into month-end.
