BTC skew leans up while ETH quietly hedges its downside
Bitcoin sits at $66,180 with a balanced crowd and a positive 25-delta skew, calls carrying the small premium. Ether tells a slightly different story: the tape has been hotter than options price, and the skew tilts fractionally toward downside protection.
Positioning & volatility
| Asset | Funding (blended) | 25Δ skew | Implied / realized vol | Open interest |
|---|---|---|---|---|
| BTC | +2% (HL +7 / OKX -4) | +3.0 | 36.9 / 35.3 | $2.42B |
| ETH | +4% (HL +11 / OKX -3) | -0.6 | 50.8 / 46.1 | $2.00B |
| SOL | +2% (HL +0 / OKX +4) | n/a | n/a / 43.2 | $0.36B |
Funding annualized; negative means shorts pay longs. 25Δ risk reversal in vol points; negative means downside hedged. Snapshots, not positions.
Funding is balanced across all three coins, so nobody is leaning hard either way in the perp books. BTC's 25d skew reads +3.0 with implied at 36.9 against realized 35.3, a market that prices only a touch above the recent tape and slightly favors upside tails. ETH is the more interesting read: skew -0.6 means the downside tail is marginally bid, and implied 50.8 versus realized 46.1 says traders are paying up for calm-looking vol even though the actual moves have been smaller. SOL has no options read, but funding at both venues agrees and realized sits at 43.2.
What the prediction markets believe
Kalshi prices BTC holding above $64,000 at 100%, essentially dead-on fair, so the prediction market and options agree there is no near-term downside scare priced.
On-chain vs Wall Street
The on-chain tokenized names are all pricing an up open, led by CRCL at +437bp and COIN at +291bp over their last closes, with NVDA, GOOGL and TSLA all higher too. That is a broad risk-on lean into the session from the tokenized book.
| Stock | Last close | Token vs last close |
|---|---|---|
| CRCL | $65 | +437 bp |
| COIN | $161 | +291 bp |
| NVDA | $203 | +104 bp |
| GOOGL | $352 | +75 bp |
| TSLA | $370 | +75 bp |
Tokenized equities trade around the clock; gaps are vs the last regular-session close, a read on where the on-chain market prices the open.
Bottom line
Watch whether ETH's small downside skew and cheap-looking implied resolve toward the hotter realized tape or fade back. The tokenized-equity gaps point to a green open on-chain, and BTC's positive skew says the calls are still the ones getting paid a hair more.
