While the spot market spent Friday nursing its Hormuz headache, somebody in the options market was quietly building the most aggressive bullish position we have seen this month. Per CoinDesk's July 18 reporting, block trades on Deribit accumulated 20,000 contracts of the $70,000 bitcoin call expiring July 31, paired with the sale of 20,000 contracts of the $72,000 call on the same expiry. Total notional value: roughly $2.5 billion. The structure is a bull call spread, and its message is precise in a way that outright call buying never is. Whoever placed it expects bitcoin to climb from the current $64,000 area toward $70,000 within two weeks, does not expect it to run much past $72,000, and wanted the position cheap enough to size enormously.
The date is not an accident. July 31 sits two days after the Federal Reserve announces its rate decision on July 29, the anchor event we flagged in our July pivot piece at the start of the month. This is a Fed trade wearing an options costume.
What the spread actually says
A bull call spread is the options market's way of saying "up, but not to the moon". Buying the $70,000 call alone would pay without limit on any rally, but the premium on a two-week out-of-the-money option is expensive. Selling the $72,000 call against it hands back all the upside above that level in exchange for a much lower net cost. The result is a defined bet: worthless if bitcoin stays below $70,000 at expiry, maximum payout if it settles above $72,000, with a straight line between the two. Deribit's chief commercial officer Jean-David Pequignot confirmed the pattern, noting "This week we have seen some large blocks in BTC topside call spreads" in the exchange's flow.
Size and precision are what separate this from retail lottery tickets. Per CoinDesk, flow of this scale and repetition usually reflects institutional positioning, since the capital required and the exact strike selection are not how small accounts behave. From spot near $63,866 when the trade was reported, the lower strike requires roughly a 10 percent rally in under two weeks. That is a demanding move, but it is the same distance bitcoin covered in the opposite direction earlier this month, when it fell from the mid-$60,000s to under $58,000 before recovering. Two-week 10 percent swings are simply what this market does in 2026.
The calendar this bet lives on
The macro setup gives the bulls a real case. June's inflation data showed a sharp deceleration, with core prices flat, the print that fueled Tuesday's relief rally. Fed funds futures put the odds of a hold at the current 3.5 to 3.75 percent range in the 75 to 80 percent zone, which means a cut is priced as a live minority outcome rather than a fantasy. If the Fed cuts, or holds while signaling September easing, a squeeze toward $70,000 is exactly the kind of move crypto produces when positioning is caught lean.

The case against is the one we wrote up on Saturday. The Hormuz disruption is now priced as a duration event, not a headline event, and a persistent oil premium is precisely the ingredient that could harden the Fed's language even with June's inflation cooling. The spread's cap at $72,000 quietly acknowledges this tension: even the bulls behind a ten-figure position are not paying for outcomes beyond a 13 percent rally. They are betting on relief, not on a new regime.
What we are watching
Our read is that the trade is most useful as a sentiment instrument. It tells us serious money considers the July 29 meeting the month's decisive moment and leans toward a bullish resolution, while capping its own optimism. For the tokens on our airdrop tracker, the implication cuts both ways: a Fed-driven rally into early August would hand new distributions their first friendly backdrop in weeks, while a hawkish surprise lands right as Grass claimants receive USDC on July 22 and decide whether to hold or rotate. Watch the July 31 expiry either way. When $2.5 billion in options settles two days after a Fed decision, the pin risk around $70,000 to $72,000 can shape the tape all by itself. None of this is financial advice, and a spread this size can be hedged, rolled or unwound long before we ever learn who placed it.
