πͺ COIN's $19.7M Two-Expiration Call Trade, Resolved β Only the Hedged October Leg Was New Money
π August 10, 2026 | π€ Negotiated Floor Block
π Updated 2026-08-11 pre-market β the next-day OPRA open interest resolved both legs, and one inverted. The October $150 calls opened exactly as predicted (345 β 9,858, +9,513 against a 9,425-lot print, inside our published 9,700β9,800 window). The August $160 calls did not: open interest fell 13,002 β 11,501, where an opening would have pushed it toward β22,000. That leg was not new bullish money, so the provisional BTO label is retired. See the β RESOLVED box.
π― The Quick Take
A desk positioned $19.70 million of Coinbase call options at 11:23:35 ET today β 9,425 contracts of the October $150 calls and 9,425 contracts of the August $160 calls, both bought at the same moment as one negotiated package. It printed as a floor block (a manually worked trade with a known counterparty on an exchange floor), not a lit sweep, so there's no urgency here β a broker matched two sides who'd already agreed on price. And the twist: the bigger leg, the October $150 calls, came attached to a paired stock position in the equity tape, which means part of this package is delta-hedged rather than a pure upside bet. We'll walk through exactly what that means below.

π° The Trade, Plain English
Two call legs, same 9,425-contract size, same timestamp, printed together as one package:
- Bought 9,425 October 16 $150 calls for $16.73M β this is the larger leg, and it's the one with a paired stock position attached in the equity tape.
- Bought 9,425 August 21 $160 calls for $2.97M β the smaller, nearer-dated leg.
Combined debit: β$19.70M paid, with COIN trading around $148.90 at the time of the print.

β RESOLVED β One Leg Opened Exactly as Predicted, the Other Went the Other Way
Updated 2026-08-11 pre-market. Resolving OPRA snapshot timestamped August 11 (reflects the August 10 close); baseline is the August 10 snapshot (reflects August 7 β before this print).
| Leg | Baseline (Aug-10) | Resolving (Aug-11) | Ξ | Print size | Ξ as % | Day vol | Our published prediction | Verdict |
|---|---|---|---|---|---|---|---|---|
| Oct-16 $150 call (bought) | 345 | 9,858 | +9,513 | 9,425 | +100.9% | 9,603 | "9,700β9,800" | β OPEN (BTO) β confirmed |
| Aug-21 $160 call (bought) | 13,002 | 11,501 | β1,501 | 9,425 | β15.9% | 10,194 | rise to β22,000 or fall | π NOT AN OPEN β was BTO β³ |
The October leg landed on our number. Open interest rose from 345 to 9,858 β a gain of 9,513 against a 9,425-lot print, inside the 9,700β9,800 window we published (the small overshoot is other flow at the same strike). That leg is a proven, brand-new position.
The August leg resolved on the closing side of the fork, and this is the correction that matters. We wrote that if this leg were opening, open interest would rise toward β22,000, and if closing, it would fall. It fell β 13,002 to 11,501. So the default BTO label was wrong: on net, this print did not add open interest to the $160 strike. Buying a call closes a position when the buyer was short it to begin with, and net open interest at the strike declined by 1,501 even as 10,194 contracts changed hands on the day.
Read the size honestly, though: this is a partial, muddy result, not a clean close. Open interest fell by only 1,501 against a 9,425-lot print β roughly 16%. The bulk of the print transferred contracts between holders rather than creating or retiring them. The defensible statement is: the August $160 calls were not new bullish money. Any framing of that leg as "a bet COIN clears $160 in 11 days" is retracted.
π€ What This Actually Means β Plain English
Here's the honest read, leg by leg:
The October $150 calls are a proven fresh position β but they're not a clean directional bet. Because this leg carries a paired stock trade in the equity tape, the buyer (or the desk executing on their behalf) also moved shares alongside the calls. When an options position ships with a stock leg attached like this, it typically means some or all of the option's delta is being offset β the package is engineered for a specific risk profile (financing, a synthetic structure, a hedge against an existing position, or a controlled way to gain exposure with less directional punch) rather than a straightforward "I think COIN goes up" wager. We genuinely don't know the buyer's exact motive β that detail lives with the broker and the client, not on the tape β but the presence of a paired stock leg is the single most important nuance here, and it argues against reading this as a simple bullish call purchase.
The August $160 calls were the pure directional piece β and the open interest says they were not new money. There's no stock leg attached to this one in the same way. On the day we could not prove open versus close; the next-morning snapshot showed open interest falling 13,002 β 11,501. That rules out the reading we flagged as conditional β this was not a fresh bet that COIN clears its nearest heavy resistance ($160, see the gamma section below) within 11 days. It was, on net, chips coming off a prior position, with most of the print transferring between holders rather than retiring outright.
Order type honesty: the classifier defaulted both legs to BTO (bought to open). The October leg confirmed β open interest rose 9,513 against a 9,425-lot print. The August leg did not: open interest fell 1,501, so the BTO default was wrong there and has been retired. This is exactly why the provisional marker existed, and exactly why a classifier default should never be published as a fact.
Bottom line, now resolved: this was an engineered, two-expiration options package with a hedged core (Oct $150C + stock, confirmed opened) and an August wing that turned out not to be new directional exposure at all β not a straightforward "someone's betting big on Coinbase" headline, and less bullish than even our cautious version implied. A buyer stepping into calls here is also leaning against a stock that's down more than a third year-to-date and over half in the past year, in a name with 3.36 beta β worth remembering before reading too much conviction into the dollar figure.
π Technical Setup
Year-to-Date Chart

COIN has been in a sustained downtrend through 2026, down β36.6% year-to-date and β52% over the trailing 52 weeks, with a 52-week range of $139.11β$402.16. The stock hit a fresh 52-week low of $139.15 in early August following the Q2 earnings miss, and it's been grinding along the bottom third of that range since.
Gamma-Based Support & Resistance

With COIN near $149.85, the gamma map shows:
π΅ Support below spot:
- $149 β Moderate strength, essentially right at the current price
- $145 β Moderate strength, β3.2% below spot
- $140 β Moderate strength, β6.6% below spot
π Resistance above spot:
- $150 β Strong, essentially at-the-money right now β this is exactly where the October $150 call leg struck, meaning that position opened almost right on top of the nearest overhead wall
- $155 β Strong, β3.4% above spot
- $160 β Strong, β6.8% above spot β this is the single largest resistance level on the board, and it's exactly where the August $160 call leg is struck
The alignment is notable either way you read it: the October $150 calls opened right at the market's current pin level, while the August $160 calls are targeting the heaviest resistance wall in the chain. The $160 leg did not turn out to be a genuine new opening position β open interest fell (see the β RESOLVED box above) β so the "buyer betting COIN clears the toughest overhead level within 11 days" reading does not apply.
Implied Move

The options market is pricing in:
- Weekly (Aug 14, 4 days): Β±7.5% (Β±$11.19) β range $138.68 β $161.06
- Monthly OPEX (Aug 21, 11 days β matches the $160 call leg): Β±11.4% (Β±$17.12) β range $132.75 β $166.99
- Triple Witch (Sep 18, 39 days): Β±21.4% (Β±$32.02) β range $117.85 β $181.89
- October 16 OPEX (67 days β matches the $150 call leg): implied range roughly $109.31 β $190.43
Two things worth noting: the August $160 strike sits comfortably inside the market's own 11-day implied-move upper bound ($166.99), so the options market isn't pricing that strike as a moonshot β it's a real, if uncertain, possibility. And the October $150 strike is essentially at-the-money, well inside the wide 67-day implied range, which is consistent with a hedged, lower-conviction structural position rather than a lottery-ticket bet.
πͺ Catalysts
β οΈ Read the calendar carefully β the two expirations in this trade cover very different windows
August 21 expiration (the $160 call leg): essentially no scheduled company catalyst inside it. The Senate is in recess until September 14, so even the dominant regulatory storyline is quiet through this contract's life. What can move COIN before August 21 is largely macro and unscheduled: bitcoin and ether price action, U.S. rate-cut expectations, and continued analyst reaction to the Barclays downgrade to Underweight ($140 target) and Weiss Ratings' downgrade to Sell in early August. This contract is, in practice, a crypto-beta and volatility-decay instrument, not a catalyst play.
October 16 expiration (the $150 call leg): captures the CLARITY Act vote and September FOMC β but NOT earnings. On August 8, 2026, Senate Majority Leader John Thune filed cloture, scheduling a procedural vote on the CLARITY Act (digital asset market structure bill) for September 15, 2026 at 2:15 p.m. ET. That vote needs 60 votes to succeed β with Republicans holding 53 seats, at least seven Democrats or independents would need to cross over β and unresolved sticking points include ethics provisions, illicit-finance language, and Senator Josh Hawley's deposit-flight objections. The September 15β16 FOMC meeting also falls inside this contract's life, as does the βSeptember 21 S&P 500 quarterly rebalance. What this contract does NOT cover: Coinbase's expected Q3 2026 earnings, estimated at βOctober 29, 2026 (unconfirmed) β roughly 13 days after the October 16 expiration. Anyone assuming this October contract "covers earnings" is wrong on the calendar.
What already happened (context for the setup)
- Q2 2026 earnings, July 30, 2026 β a double miss. Revenue of $1.22B (β19% Y/Y) versus $1.29B consensus, and GAAP EPS of β$1.36 versus β$0.01 expected β the company's third consecutive GAAP loss. Shares fell β5% after hours and later touched a 52-week low of $139.15.
- Cost discipline was the bright spot. Adjusted expenses fell 9% sequentially after a 14% headcount cut, and Coinbase posted its 14th consecutive quarter of positive adjusted EBITDA ($207.8M), with a record 10.3% share of global crypto trading volume and prediction-markets revenue up 106% quarter-over-quarter.
- Crypto prices are down hard. Bitcoin is β44.1% year-over-year and ether β48.4%, and Coinbase's CFO said industry spot volumes fell more than 20% in the quarter β directly driving the revenue miss.
- The rate-cut paradox. Lower rates tend to help crypto prices, but they also compress the interest Coinbase earns on USDC reserves β roughly $75β80M of annualized revenue at risk per 25bp Fed cut, on Coinbase's 50/50 split with Circle. Coinbase has responded by paywalling USDC rewards for non-subscribers.
π¬ Four Ways to Read This β By Trader Type
π YOLO trader: If you're chasing the $160 call leg specifically, understand you don't yet know whether it's a fresh position or someone closing out β that resolves tomorrow. Even if it is new, it's a bet on clearing the single strongest resistance wall in the chain within 11 days, with no scheduled company catalyst in that window. Sizing this small and waiting for the OI confirmation before adding is the more responsible version of this trade.
π Swing trader: The October $150 calls are the more interesting structural setup β a confirmed fresh position, struck essentially at the money, that lives through the September 15 CLARITY Act vote and FOMC. But remember it's paired with a stock leg, so it isn't a clean read of institutional bullishness; if you want directional exposure into that regulatory window, build your own position rather than assuming this trade validates one.
π° Premium collector: This isn't a premium-selling setup on either leg β both are BUY/BTO calls, meaning the counterparty here collected the premium, not the desk we're analyzing. If you're looking to sell premium against COIN's elevated implied volatility (11.4% over 11 days, 21.4% over 39 days), consider that separately, sized to the stock's 3.36 beta and its still-negative price trend.
π± Beginner: The single most useful lesson from this trade is patience with incomplete information. One leg (October $150C) is provably a new position; the other (August $160C) genuinely cannot be classified yet from today's tape alone. Waiting for tomorrow's open-interest confirmation before drawing conclusions β rather than reacting to the $19.7M headline β is exactly the right instinct here.
β οΈ Honest Limits β What the Tape Cannot Prove
- We cannot see the buyer's identity, broker, or account type. The tape shows contracts and prices, not who's on the other side or why.
- We cannot confirm the August $160 call's open/close status until tomorrow's OI snapshot. Treat any "bullish bet on $160" framing for that leg as provisional until then.
- We cannot see the exact size or direction of the paired stock leg on the October $150 calls, only that a stock+options combination condition applies. That means we can't quantify how much of the option's delta is actually offset β only that it isn't a "pure" long call.
- We cannot know the buyer's underlying motive β hedge, financing structure, synthetic positioning, or a straightforward directional view with a partial hedge attached are all consistent with what the tape shows. Ruling any of these in or out with confidence would be overstating what the data supports.
- Q3 2026 earnings date is unconfirmed (βOctober 29 is a forecast, not a company-issued date), and no probability estimate exists for CLARITY Act cloture passage β do not treat either as settled.
This is options-flow analysis, not investment advice. Options trading involves substantial risk of loss and may not be suitable for all investors. COIN carries elevated volatility (5-year beta 3.36) and is down sharply over the past year β position size accordingly and manage risk before chasing any single print.
Last updated: 2026-08-11 (pre-market) β the next-day OPRA open-interest snapshot resolved both legs. Oct-16 $150C 345 β 9,858 (+9,513): OPEN, inside the published prediction window. Aug-21 $160C 13,002 β 11,501 (β1,501): not an open β the provisional BTO label is retired and every bullish framing of that leg has been withdrawn.
