Ainvest Option Flow Digest - 2026-05-28: ≈$115M Across 13 Names — Twin $21M Semicap Put Hedges, a $25M Seagate Short-Call Roll, a Defense Drone Call, and a Tape Full of Negotiated Crosses (Not Sweeps)

A calm read of where large options money went today — and what it actually means. Today's standout: two $21M downside-protection blocks on the biggest chip-equipment names (KLAC + LRCX) printed the same day — a coordinated semicap-cycle hedge, not a crash call. Just as important, 11 of today's 13 prints were negotiated block crosses (a known counterparty on the other side), not aggressive lit-market sweeps. Only MSFT and SMTC were genuine sweeps. Two late adds round out the tape: a defense-drone recovery bet (KTOS) and a multi-year private-equity hedge (CG). Read the mechanism, not just the dollar headline.

✅ OI UPDATE (2026-05-29) — we ran the next-day open-interest double-check. The OPRA open-interest snapshot reflecting 2026-05-28 EOD is in, and it resolved every provisional flag from yesterday. 11 of 13 names confirmed exactly as written (genuine opens). Two changed: (1) STX inverted — the "bullish diagonal" was actually a short-call roll (the $650 call closed a short, OI 2,353→1,539; the $900 call opened a new short, OI 521→2,014); its section below is corrected. (2) SMTC's $240 leg confirmed open (OI 17→593) but its $150 leg did not register net-new open interest (678→609). This is exactly why we tell you to come back the next morning — the tape alone can mislabel deep-ITM, size-below-OI prints, and the OI snapshot is the ground truth.

The Quick Read

We tracked roughly $115M of net options premium across 13 tickers (net/structural — several are spreads or financed structures where the gross dollar figure overstates the real bet). The clear themes:

• 🛡️ Twin semicap put hedges ($42M combined): KLAC — 1,500 of the Aug 21 $1,740 puts for $21M (spot ≈$1,957). LRCX — 7,500 of the Aug 21 $290 puts for $21M (spot ≈$319). Both printed as single-leg block crosses, both expiries straddle the names' late-July/early-Aug earnings. Two desks (or one) bought downside protection on the two biggest chip-equipment names on the same day. This is hedging the semicap factor — AI-capex-peak risk, China export controls, the 2027 WFE-downcycle debate — NOT a single-name short. Honest read: a put buy alone is equally consistent with protecting a large long; the coordinated twin is the tell.

• 🔄 A $25.5M Seagate short-call ROLL (updated — the read inverted): STX — 1,752 Jun-18 $650 calls + 1,752 Jul-17 $900 calls, net ≈$25.5M, printed as a stock+option combo. ✅ The 2026-05-29 OI snapshot resolved this — and it was NOT a fresh bullish bet. The $650 call BUY closed an existing position (OI fell 2,353 → 1,539) and the $900 call SELL opened a new short (OI rose 521 → 2,014). So a desk that was short the June $650 calls — now ≈$221 in-the-money as STX ripped to ≈$871, facing near-certain assignment — bought them back and rolled the short up to July $900. It's a short-call/overwrite roll up-and-out: mildly bullish (the cap moved up $250) but fundamentally premium management on a short position, not new long conviction. Most of the $25.5M was the cost of exiting the deep-ITM short.

• ⚡ The only two real sweeps: MSFT — $9M of Jun-26 $440 calls bought aggressively (lifting the offer) into Build 2026 (Jun 2-3), an oversold-mean-reversion bet (MSFT ≈−14% YTD). SMTC — $2.4M of Jan-2027 $150 + $240 calls swept after a blowout AI-interconnect quarter.

• 🐋 Bullish single-name LEAPs / blocks: IREN $8.1M three-leg (Jan-2028 $110 LEAP + short Jun-5 $62/$65 puts) — a continuation of yesterday's convertible-cap play. NET $5.3M Jan-2027 $290 LEAP. INTC $4.3M Dec-2027 $150 LEAP. IBM $3.4M Aug $295 call.

• 🐻 Contrarian / bearish / hedge: BSX $9.1M bull call spread + short put — a fallen-angel recovery bet (BSX crashed ≈−47% YTD after two guidance cuts). NKE $2.8M Jan-2027 $42.50 put — downside/hedge on Nike near an 11-year low. CG $2.1M Jan-2028 $40 LEAP put — a multi-year hedge over the private-equity cycle on Carlyle (Q1 GAAP loss, two downgrades, −19% YTD); most likely insurance over a long position, not an aggressive short.

• 🚀 Defense: KTOS $1.2M Aug $85 call (≈30% OTM) — a bullish mean-reversion bet on Kratos, which popped ≈15% today on a WSJ report the Trump admin may take stakes in US drone makers. Honest nuance: Kratos was NOT named in that report (it targets cheap FPV attack drones, not the Valkyrie), so today's pop is a sentiment headline, not a Kratos contract. The $85 strike sits below the Street's $93-116 target after KTOS fell ≈58% from its January high.

A large print shows what one participant did with size — not what will happen. Today's two biggest tickets are protective put hedges, and most of the rest are negotiated crosses with a counterparty on the other side. None of this is "urgent buying pressure." Read the open/close direction and the structure; size so a total loss of premium wouldn't hurt; never chase a print after the move already happened.

Today's Flow at a Glance

Premium figures match each detailed analysis. For spreads/financed structures (STX, BSX, IREN) the net debit is what's at risk, well below the gross dollar headline. The two semicap puts ($21M each) are premium paid for protection.

The Whale Lineup

1. 🛡️ KLAC + LRCX — Twin $21M Semicap Put Hedges (The Day's Real Story)

See the coordinated semicap-factor hedge →

• What's happening: Same day, two of the biggest chip-equipment names each drew a $21M put block. KLAC: 1,500 Aug $1,740 puts (spot ≈$1,957, ≈11% OTM), OI was 0 = fresh. LRCX: 7,500 Aug $290 puts (spot ≈$319, ≈9% OTM). Both single-leg block crosses.
• Why it's a factor hedge, not a short: Both names are parabolic (LRCX +282% YTD post-split; KLAC at all-time highs, +154% over 12 months) and share identical risks — AI/HBM-capex peak, China export controls, the openly-debated 2027-2028 WFE downcycle. A single adverse headline hits both. Buying puts on both = hedging the theme. Both expiries straddle the names' Q4 earnings (KLAC ≈Jul 30, LRCX ≈Aug 5).
• Honest read: A put buy alone doesn't prove a directional short — it's equally consistent with a desk protecting a large long semicap book into earnings. Morgan Stanley downgraded KLAC to Equal-weight on valuation, which adds a bearish data point, but the cleanest interpretation is risk management at a cycle high.

2. 🔄 STX — $25.5M Seagate Short-Call Roll (✅ OI-confirmed: a roll, not a bullish bet)

See the structure →

• What's happening: 1,752 Jun-18 $650 calls (≈$44.6M, deep ITM at spot ≈$871) + 1,752 Jul-17 $900 calls (≈$19.1M credit), net ≈$25.5M. Printed as a stock+option combo block (hedged/facilitated).
• ✅ Open/close RESOLVED (2026-05-29) — and it inverted: the $650-call BUY reduced open interest (2,353 → 1,539, Δ−814) = a buy-to-close of an existing short; the $900-call SELL added open interest (521 → 2,014, Δ+1,493) = a sell-to-open of a new short. So this is a short-call roll, not a bullish diagonal. The desk was short the June $650 calls, that short went ≈$221 in-the-money as STX ran to ≈$871 (near-certain assignment), so they bought it back and re-wrote the short up at July $900.
• The engineering: the desk lifted its cap from $650 to $900 and pushed it out from June to July, financing part of the buy-back with the new $19.1M credit. The new short $900 leg expires Jul 17 — one day after Q4 earnings (Jul 16) — so the desk is again short calls directly over the earnings binary, now at $900 instead of $650.
• The read: mildly bullish as an adjustment (you only pay $25.5M net to lift your own ceiling if you want more room) but the posture is still short calls / capped — overwrite income management, not fresh long conviction. The bullish-conviction interpretation has the sign of the trade backwards.
• The backdrop: Seagate is the sole at-scale HAMR supplier (44TB Mozaic drives shipping to hyperscalers), nearline capacity sold out through 2026. The median analyst PT (≈$771) sits below spot — consistent with a desk that wants to keep selling the upside above $900 rather than buying it.

3. ⚡ MSFT — $9M Aggressive Call Sweep Into Build 2026

See the day's most urgent bullish print →

• What's happening: 9,889 Jun-26 $440 calls bought at $9.10 (≈$9M), spot ≈$426. Crucially, this was a genuine lit-market sweep (the buyer lifted the offer) — not a negotiated cross like most of today's tape. That makes it a stronger directional signal.
• The catalyst: Microsoft Build 2026 (June 2-3) sits inside the Jun-26 expiry. Q4 earnings (Jul 28) are after expiry — so this is a Build + oversold-mean-reversion bet, not an earnings play. MSFT is ≈−14% YTD on the $190B capex shock; consensus PT ≈$565.
• The risk: Theta. A 29-day, 3%-OTM call with the catalyst on day 5 — if Build underwhelms, the clock runs mercilessly. The capex overhang is structural and Build won't fix it.

4. 🐋 IREN — $8.1M Three-Leg Bullish Block (Convertible-Cap Continuation)

See the $110.30-cap play, day two →

• What's happening: BUY 4,000 Jan-2028 $110 LEAP calls (≈$11.1M) + SELL 4,006 each of Jun-5 $65 and $62 puts (≈$3M credit), net ≈$8.1M.
• The thesis: The $110 strike = IREN's convertible capped-call cap price of $110.30 from the May 12 $2.6B converts. The same LEAP was bought yesterday — this is a deliberate "ride the convertible cap" add. The short near-ATM Jun-5 puts (no earnings before then) are aggressive bullish financing.
• The risk: Short puts = obligation to buy at $62-65 if IREN dips by Jun 5. Still ≈77% Bitcoin-mining revenue (BTC drawdown risk). JPMorgan Underweight $46 vs Cantor $99 — a wide split.

5. 🐻 BSX — $9.1M Contrarian Recovery Bet On A Fallen Angel

See the bull call spread + short put on a −47% name →

• What's happening: BUY 102,200 Dec $67.5 calls + SELL 102,200 $85 calls (a bull call spread) + SELL 20,440 $40 puts (financing/floor), net ≈$9.1M. (An earlier identical block at 11:04 was cancelled — only the 11:07 block is genuine.)
• The setup: Boston Scientific crashed ≈−47% YTD from $109 to ≈$49 after two guidance cuts and a first-ever WATCHMAN volume decline. This is a contrarian recovery bet — profit if BSX climbs back toward $67.5-$85 by December, with the short $40 put setting an "I'd own it here" floor. Dec expiry straddles both Q2 (Jul 29) and Q3 (≈Oct) earnings — the two prints that could flip the narrative.
• The risk: Two-sided. Management's credibility took a hit; the $40 short put means real downside obligation if the slide continues.

6-9. 🐋 The Bullish LEAPs — NET, INTC, IBM, SMTC

• NET — $5.3M Jan-2027 $290 LEAP: "Cloudflare for AI" re-rate bet. Record Q1 but stock fell ≈24% on a 20% "agentic-AI-first" layoff; recovered to ≈$225. Rich (≈30x P/S), CEO sold $32.6M mid-May, needs ≈29% upside.
• INTC — $4.3M Dec-2027 $150 LEAP: Long-horizon Intel turnaround bet (+230% YTD on gov/SoftBank/NVIDIA stakes + 18A). Honest catch: 14A volume slipped to 2028/2029 (after the LEAP expires), zero committed external 14A customers, insiders selling, stock ≈30% above avg PT.
• IBM — $3.4M Aug $295 call: Contrarian value-reset on 2026's worst mega-cap (≈−25% YTD). $295 ≈ Street avg PT; Q2 ≈Jul 22 inside expiry. But IBM beat in Q1 and still fell 6% — a 12%-OTM single-event call is a high bar.
• SMTC — $2.4M Jan-2027 $150 + $240 calls (⚡ sweeps): Aggressive AI-interconnect bet after a blowout Q1 FY27 (CopperEdge 1.6T active-copper cables shipping to a US hyperscaler). $150 = delta-heavy continuation; $240 = convexity above the Street-high PT. ✅ 5/29 OI: the $240 convexity leg confirmed as a fresh open (OI 17→593); the $150 strike did not register net-new OI (678→609), so lean on the confirmed $240 leg for the signal.

10. 🐻 NKE — $2.8M Bearish/Hedge Put Near An 11-Year Low

See the Nike downside bet →

• 6,500 Jan-2027 $42.50 puts (spot ≈$45). Nike ≈−30% YTD, near an 11-year low; turnaround dragging, China ≈−20%, ≈$1.5B tariff hit. The long-dated put spans three earnings prints (Q4 FY26 Jun 25, Q1/Q2 FY27). Honest counterweight: the 2026 FIFA World Cup (Jun 11-Jul 19) is a ≈$1.3B tailwind inside the window.

Read It By Your Style

Not recommendations — just how disciplined approaches might think about today's tape. Risk control first.

• 🎲 YOLO / event trader: MSFT is the cleanest event play — an aggressive sweep into Build 2026 (Jun 2-3), defined risk = premium, but theta is brutal after day 5. SMTC's $240 convexity leg is the high-octane lottery (≈53% OTM). Both are premium-fully-at-risk; size ≤1%.
• 📈 Swing trader: IBM and NET are catalyst-dated directional views into July earnings. STX is NOT a directional template — the OI proved it's a desk rolling a short call (closing the June $650 short, re-writing July $900); it tells you a sophisticated desk expects $900 to cap the stock into July, not that it's loading up long. The semicap puts (KLAC/LRCX) are hedges, not swings.
• 💵 Premium collector: Today's lesson lives in the structures. BSX and IREN sold options to finance bullish bets (short $40 BSX puts, short $62/$65 IREN puts); STX is the purest premium-collection example of all — a desk rolling a short call up-and-out ($650→$900), staying short the upside to keep harvesting premium. Each short leg carries a real obligation (assignment, capped upside). The semicap put buyers (KLAC/LRCX) are on the other side of that trade — paying for protection.
• 🌱 Just getting started: Two lessons today. (1) A "put buy" is not automatically a crash call. KLAC and LRCX's $21M puts are most likely insurance on winning longs, not bearish bets. (2) Mechanism matters. 9 of today's 11 prints were block crosses — a broker matched two parties off the open order book, so there's a known counterparty and it's deliberate positioning, NOT urgent buying pressure. Only MSFT and SMTC "swept" the lit market (a stronger directional signal). When you see a big premium number, ask: was it bought or sold, opening or closing, swept or crossed?

Upcoming Catalysts — Event vs. The Option That Plays It

Risk & Reminder

Large prints look like signals; they're often one institution rebalancing a book. Five things to remember:

1. Open/close + mechanism beat the dollar headline. Today's two biggest prints are protective puts (hedges), and 9 of 11 are negotiated crosses with a counterparty on the other side. None of it is "urgent buying."
2. A put buy ≠ a crash call. KLAC/LRCX's $21M puts are most likely insurance on large semicap longs at a cycle high — not bearish conviction.
3. Spreads and financed structures overstate the headline. STX's "$44.6M" buy leg is really a ≈$25.5M net roll (and most of that was the cost of closing a short, per the next-day OI); BSX's gross is ≈$25.5M but ≈$9.1M net. Read the net debit — and the open/close direction.
4. Sweeps are rarer and stronger. Only MSFT and SMTC lifted the lit-market offer today — that urgency is a cleaner directional tell than a negotiated block.
5. Long-dated LEAPs need time AND a re-rate. NET ($290), INTC ($150), IBM ($295) all need both multiple expansion and clean execution — most OTM LEAPs expire worthless.

Read every detailed analysis, never copy without doing your own homework, size so a total loss of the premium wouldn't hurt, and remember the best traders are the most patient — not the most reactive.
