Bitcoin's options market on Deribit has developed a striking concentration of bullish positioning: the $70,000 and $72,000 call strikes have together accumulated a notional open interest of nearly $5 billion — approximately 18% of the platform's total $28 billion in BTC options open interest — making them the two most popular contracts on the exchange. At the $70,000 strike, approximately 39,000 calls are active versus 3,800 puts. At the $72,000 strike, roughly 37,900 calls stand against only 1,200 puts. The heavily skewed call-to-put ratios reflect an unambiguously bullish positioning structure. But the catalyst that Orbit Markets identified as a primary driver of this positioning — Clarity Act optimism — is fading rapidly. Polymarket odds of the Clarity Act being signed into law in 2026 fell to 38% from 51% earlier this week after Senate Majority Leader John Thune said he does not expect the Senate to pass the bill before August recess.
The $5 Billion Structure — Bull Call Spreads Dominate
The $5 billion notional open interest concentration at two adjacent strikes is not random accumulation — it reflects a specific and deliberate options strategy executed at scale. Laevitas identified the dominant structure as a bull call spread: buying the $70,000 call and simultaneously selling the $72,000 call. The bull call spread limits the buyer's maximum profit to the difference between the two strikes — $2,000 per Bitcoin — while reducing the net premium paid versus buying the $70,000 call outright. It is the classic options structure used when a trader has high conviction that price will reach a moderate upside target within a specific timeframe rather than an unlimited upside bet.
The scale of this structure is what makes it analytically significant. Laevitas noted that the bull call spread accounts for approximately 49% and 50% of total call open interest at the $70,000 and $72,000 strikes respectively — meaning roughly half of the $5 billion notional concentration at these two levels is a single coordinated strategic position rather than organic retail accumulation from thousands of individual trades. A single trader or coordinated group has built a position representing approximately $2.45 billion notional exposure specifically targeting Bitcoin reaching $70,000-$72,000 by the July 31 expiry.
A separate trader or group purchased a large number of $70,000 calls outright, paying $3.4 million in premium to gain pure upside exposure. Calendar spreads — designed to profit from volatility changes between short and near-term expiries — round out the notable recent trades, suggesting that sophisticated participants are also positioning for the BVIV's rise from 37.5% to 40% to continue or for the FOMC meeting to produce a significant volatility event.
The Clarity Act Catalyst — From 51% to 38% in One Week
Jimmy Yang, co-founder of Orbit Markets, identified the primary driver of the $70,000-$72,000 call concentration: "Earlier this month, we saw decent demand for BTC topside calls, with the 31 July $70,000 and $72,000 strikes being particularly popular. A lot of this positioning was driven by expectations that the CLARITY Act could be passed before the end of the month."
The Clarity Act — which would establish clear regulatory jurisdiction between the SEC and CFTC over digital assets — has been the most consequential pending piece of US crypto legislation since the Bitcoin ETF approvals. The White House's agreement to ethics package wording earlier this week had lifted Polymarket odds toward 51% for a 2026 signing. That optimism has now reversed sharply: Senate Majority Leader John Thune said he does not expect the Senate to pass the bill before the body adjourns for its August recess, sending Polymarket odds from 51% to 38% in approximately 24 hours.
Yang confirmed the market impact directly: "In the last 24 hours, the market has dialed back those expectations, leading to unwinding of some of these bullish bets." The unwinding of Clarity Act-driven $70,000-$72,000 call positions is the specific mechanism behind any Bitcoin weakness that cannot be fully explained by oil's move above $100 or the 13th consecutive night of US-Iran strikes — there is a second simultaneous headwind from regulatory optimism being repriced lower.
The Call-to-Put Ratio — What 10:1 and 32:1 Mean
The call-to-put ratios at the two concentrated strikes are the most direct measure of the options market's directional bias. At $70,000: 39,000 calls versus 3,800 puts is approximately a 10:1 call-to-put ratio. At $72,000: 37,900 calls versus 1,200 puts is approximately a 32:1 call-to-put ratio. These are not ratios that reflect a balanced market hedging against both upside and downside — they reflect a market with overwhelming directional conviction that Bitcoin will reach these levels within the July 31 expiry window.
The 32:1 ratio at $72,000 is particularly significant because the $72,000 strike is the short leg of the bull call spread — the level at which the spread's maximum profit is realized. A 32:1 call-to-put ratio at the profit ceiling of the dominant spread structure means the market is pricing essentially no downside hedging need at $72,000 within the July 31 window. Either the spread sellers are expressing confidence that $72,000 will not be reached — in which case they collect the premium from the spread buyers — or the call buyers are expressing confidence that $72,000 will be reached and the spread will pay out in full.
The July 31 Expiry — Four Trading Days and Five Macro Events
The July 31 expiry that the $70,000-$72,000 positioning targets is four trading days away — and those four days contain the most concentrated macro event calendar Bitcoin has faced in the current recovery. The FOMC decision arrives July 29. Big Tech earnings — Microsoft, Meta, and Amazon all reporting — arrive this week alongside Alphabet's results from Wednesday. Oil is above $100 with no ceasefire and Trump signaling he is not ready to negotiate. Section 301 tariffs on 99.4% of US imports went into effect Friday. The Clarity Act's Senate passage before August recess now looks unlikely at 38% Polymarket odds.
For the $70,000-$72,000 bull call spread to pay out by July 31, Bitcoin needs to rise approximately 7.7% from its current $64,971 to $70,000 — a move that would require at minimum a dovish FOMC surprise and a stabilization of oil from $100. Against the backdrop of oil at triple digits, 13 nights of Iran strikes, and the Clarity Act catalyst fading, the path to $70,000 by July 31 has narrowed materially since the positioning was established.
The $3.4 million premium paid for the outright $70,000 call exposure represents real capital at risk. If Bitcoin does not reach $70,000 by July 31, both the bull call spread and the outright call position expire worthless — transferring the premium paid to the sellers of those options. The Clarity Act unwinding Yang described is the first sign that some of that positioning is being closed before expiry rather than held to the outcome.
The Broader Signal — What $5 Billion in Bullish Options Means for Bitcoin
Despite the Clarity Act headwind and the deteriorating macro environment, the existence of $5 billion in notional open interest concentrated at $70,000-$72,000 provides meaningful information about institutional conviction at these price levels. Sophisticated options traders do not build $5 billion notional positions targeting strikes that are 8-10% above current prices without a specific thesis for why those levels will be reached. The thesis was the Clarity Act plus a dovish FOMC plus a chip rebound — three catalysts that were all plausible simultaneously earlier this week.
One of those three catalysts — Clarity Act by July 31 — has been largely removed by Thune's statement. The other two — FOMC and chip rebound through Big Tech earnings — remain live. Whether $70,000 by July 31 is achievable with two of three original catalysts still in play is the specific question the options market will be repricing in real time as FOMC communication and Big Tech earnings results arrive over the next 72 hours.
