🤝 NBIS $14M LEAP Call SOLD — Collecting Premium at the $300 Wall While Street Plays Catch-Up

📅 June 15, 2026 | 🔥 Unusual Activity Detected

Updated 2026-06-16: Next-day OPRA OI resolves the "could be a close" flag — the Jan-2027 $300 call OI ROSE 8,127 → 10,172 (Δ +2,045 ≈ the 2,100 sold). This is a genuine fresh sell-to-open (overwrite/income), NOT a long holder closing.


🎯 The Quick Take

At 11:31:07 today, a desk crossed a ≈$14M single-leg block on Nebius Group (NBIS)selling 2,000 January 2027 $300 calls against a stock trading ≈$254.19. The seller collected ≈$71.25 per share in premium, pocketing roughly $14M in credit. The $300 strike sits ≈18% above today's spot and squarely on the biggest call gamma wall in the chain. With analyst consensus PTs averaging ≈$244 — now below the current price — this looks most like a classic overwrite: a large holder selling upside they don't expect to need, banking premium on a name that has already run ≈175% YTD.


📊 Company Overview

Nebius Group (NBIS) is an Amsterdam-based AI cloud and GPU data-center infrastructure company — the direct competitor to CoreWeave and a pure-play GPU neocloud:

  • Market Cap: ≈$66.8B
  • Sector / Industry: Information Technology — AI Cloud Infrastructure / GPU Data Centers
  • What they do: Nebius rents GPU compute capacity to AI companies and hyperscalers at massive scale. They are not just a bare-metal GPU rental shop — they run a full-stack software platform, making them stickier than most GPU-cloud competitors. Their two anchor customers are Meta (≈$27B deal) and Microsoft (≈$17-19B deal). NVIDIA has an equity stake and gave Nebius first-mover access to Vera Rubin NVL72 chips — the next-generation compute hardware that underpins the Meta deal starting early 2027.
  • Recent performance: Up ≈175% YTD in 2026 after a blowout Q1 where revenue surged 684% YoY to $399M. Stock pulled back from an all-time high near $280 and today surged back to ≈$261 — making this a natural spot for a sophisticated holder to trim upside via a call sale.

Flow type: 🤝 Single-Leg Block Cross — a pre-arranged negotiated block. A broker matched a seller and a known counterparty off the open book. This is NOT an urgent directional sweep, NOT a panic move. A desk deliberately structured this to collect $14M in premium.

Key number to internalize: the $71.25 option price is extraordinary — it means someone paid roughly 28% of the stock's current value just for the right to buy NBIS at $300 by January 15, 2027. That's how expensive these options are. And the SELLER is the one who collected that $71.25 per share.


✅ RESOLVED — Next-Day OI Confirms a Fresh Short (2026-06-16)

LegPre-print baseline (EOD 2026-06-12)Resolving (EOD 2026-06-15)ΔVerdict
Jan-2027 $300C (sell)8,12710,172+2,045OPEN — sell-to-open (STO) confirmed

The next-morning OPRA snapshot resolves the ambiguity: open interest rose from 8,127 to 10,172, a +2,045 gain that matches the 2,100 calls sold. A rising OI on a SELL confirms a sell-to-open — a genuine fresh short (an overwrite collecting premium ≈18% above spot). The same-day "could be a long holder closing" possibility is now ruled out: this is new short interest, an income/neutral overwrite, not a position being unwound.


🤓 What This Actually Means — Plain English

Let's slow down and decode this one, because it's the opposite of what most options flow alerts look like.

Selling a LEAP call = collecting premium, not betting on direction. When someone SELLS a call option, they receive the premium upfront. In this case, $71.25 per share × 2,000 contracts × 100 shares = ≈$14.25M deposited into the seller's account on day one. But the seller also takes on a cap — if NBIS rallies above $300 by January 15, 2027, they owe the buyer the difference. If NBIS stays below $300, the seller keeps the entire $14M and the option expires worthless.

Why $300 and why now? The $300 strike is ≈18% above the ≈$261 spot. Here is the two most likely reads:

If this is an opening (new short call): The seller is running an overwrite strategy — selling calls against a long stock position to generate income. This is one of the most common institutional strategies in the world for a stock that has already run hard. Translation: "I own NBIS, I've made a lot of money, I don't think it clears $300 by January, so I'll collect $14M and cap my upside there." The math supports this view — the average Street price target is ≈$244, which is actually below today's price. If the people who follow this stock every day think it's worth $244, selling the $300 call at $71.25 looks very well-priced.

If this is a closing (long-holder cashing out): The seller bought the $300 LEAP calls months ago when NBIS was much lower. NBIS has now surged ≈175% YTD, the options are worth $71.25 (a massive gain from wherever they were bought), and the smart move is to sell now and lock in. This is called Sell to Close — taking profits on a winning long-call position.

Why are the options so expensive? The $71.25 price on an option that is still $46 out-of-the-money tells you the market is pricing in enormous potential moves. The implied volatility on NBIS is very high — the options market is saying NBIS could move 30-57% by September alone (more on this in the implied move section). That high IV is exactly why an overwriter would want to sell these calls: when implied vol is elevated, premium collection is at its most lucrative.

The honest bottom line on direction: The tape tells us a seller collected $14M on the $300 LEAP call. It does not tell us if this is bullish (a long-holder taking gains), bearish (a short-call bet), or neutral (a covered-call overwrite on existing stock). We frame it conditionally. Next-day OI resolves it.


📈 Technical Setup / Chart Check-Up

YTD Performance

NBIS YTD Chart

NBIS has been one of 2026's most explosive AI names. Up ≈175% YTD, the stock has been on a rocket ship since the Meta deal was announced in March. After an all-time high near $280, shares pulled back and today ripped back toward ≈$261 on ≈9.4M shares — well above average volume.

Key observations:

  • 📈 Up ≈175% YTD — outperforming most AI infrastructure peers, including CoreWeave
  • 🎢 Very high volatility: the stock has swung dramatically with each catalyst (Meta deal, Q1 earnings, analyst upgrades)
  • 🎯 Consensus PT (≈$244) now below the current price — the Street is playing catch-up to a stock that has outrun their models
  • 👀 Today's surge back toward $261 (from $232 prior close) is a natural trigger for profit-taking or overwriting

Gamma-Based Support & Resistance

NBIS Gamma S/R

Current Price: ≈$261.3

The gamma map for NBIS is clearly spread across a wide chain, reflecting the high-IV / high-momentum character of this name. A few key walls stand out from the data:

🟠 Call Gamma Walls (Resistance Above Price):

  • $300 — Very Strong Call Gamma Wall. This is the single largest net-positive gamma node in the entire chain above the current price. Call GEX at $300 is the dominant feature at ≈14.8% above spot. This is the exact strike the seller targeted — and the reason the market maker community would be short gamma here, creating mechanical resistance. Getting through $300 would require strong fundamental news to overcome the hedging pressure.
  • $280 — Moderate Resistance. Another notable call gamma cluster ≈7.2% above spot. This was the stock's prior all-time high region. The market maker positioning suggests $280 is a near-term ceiling before $300 becomes relevant.
  • $270 — First Overhead Speed Bump. Lighter but present call gamma just ≈3.3% above today's print — the first level where upward momentum starts to slow.

🔵 Put Gamma Walls (Support Below Price):

  • $250 — Strong Support. The $250 strike carries significant put gamma — market makers will tend to buy dips here, making it a natural sticky level. A hold above $250 keeps the bull trend intact.
  • $240 — Next Key Support. Another large call+put gamma node at $240. The $240 zone is where multiple gamma concentrations overlap, making it meaningful floor territory if $250 cracks.
  • $220 / $200 — Deeper Support Zones. Meaningful gamma presence at $220 and $200 from the put side. These would only come into play on a significant drawdown.

Translation for traders: NBIS is stacked with gamma walls. The $300 call wall is essentially the natural ceiling for a January 2027 LEAP seller — not because $300 is impossible, but because the gamma structure makes it mechanically sticky. The $250 and $240 levels are your first meaningful support floors.


Implied Move Analysis

NBIS Implied Move

The options market is pricing enormous uncertainty into NBIS. This stock is one of the highest-IV names in the AI infrastructure space:

  • 📅 Weekly (exp 2026-06-18, 3 days): ±11.65% (±$30.40) → Range $230.42 – $291.22
  • 📅 Monthly (exp 2026-07-17, 32 days): ±31.98% (±$83.40) → Range $177.42 – $344.22
  • 📅 Quarterly (exp 2026-09-18, 95 days): ±57.15% (±$149.05) → Range $111.77 – $409.87
  • 📅 LEAP (exp 2027-01-15, ≈7 months): implied range $41.29 – $480.35

The $71.25 option price now makes complete sense. The options market is saying NBIS could plausibly trade anywhere from $177 to $344 by the July expiration alone — and the $300 strike is inside the quarterly probability cone. For a seller collecting $71.25, they need NBIS to stay below $300 by January to keep the full premium. The seller is counting on the stock NOT clearing ≈18% upside while IV eventually compresses.

The key insight: the monthly implied move upper range is $344.22 — which means $300 IS within the market's monthly probability cone. This is a high-premium sale precisely because the $300 strike isn't "safe" on a risk-of-assignment basis. The seller is being paid $71.25 for real uncertainty.


🎪 Catalysts

Already Happened (Context for the Trade)

Q1 2026 Blowout Earnings — The Reason NBIS Has Run 175% (Reported May 13, 2026)

Meta ≈$27B Deal (Announced March 16, 2026) According to CNBC's reporting and Nebius's own newsroom, Meta committed ≈$12B of dedicated GPU capacity (including first-mover NVIDIA Vera Rubin NVL72 deployment, delivering early 2027) plus up to $15B in additional capacity options. This is a structure that turns backlog directly into revenue — not a letter of intent.

Microsoft ≈$17-19B Deal (Sept 2025, Expanded Since) As disclosed in SEC filings, the Microsoft deal carries ≈$17.4B through 2031, expandable to ≈$19.4B, from the Vineland, New Jersey data center. According to The Motley Fool's analysis, the combined Meta + Microsoft potential backlog exceeds $46B — extraordinary for a company with ≈$877M in TTM revenue.

NVIDIA Equity Partnership NVIDIA made a significant equity investment in Nebius and granted them among the earliest access worldwide to GB300 and Vera Rubin NVL72 systems. This isn't just a vendor relationship — it's a strategic alignment that gives NBIS a hardware moat.

Analyst Upgrades — Street Still Catching Up


Upcoming Catalysts (The Runway Through January 2027 Expiry)

Q2 2026 Earnings — Expected Late July to Mid-August 2026 📅 Per Investing.com's tracker, Q2 results are expected ≈late July (Q2 2025 was reported August 7, 2025; exact date not yet company-confirmed). Key watch items: AI-cloud ARR trajectory toward the $7-9B exit-target; EBITDA margin durability; any new hyperscaler wins. This is the biggest binary event before January 2027 expiry.

Vera Rubin NVL72 Deployment Ramp (2026) Management's first-mover NVIDIA Vera Rubin deployment is the execution milestone that underpins the Meta capacity delivery starting early 2027. Any delay = negative catalyst. On-time delivery = continued stock momentum.

Capacity Milestones — 800-1,000 MW Connected by YE2026 Nebius plans to exit 2026 with 800-1,000 MW of connected data-center capacity (up from ≈170 MW at end-2025). Each site energization is a discrete positive catalyst.

Additional Financing Rounds Management signaled intent to raise mid-single-digit billions more in debt/asset-backed structures near-term to fund the $20-25B CapEx. Terms and potential dilution are watch items — bad terms could weigh on the stock.

New Customer/Contract Announcements Management reported a record pipeline and larger deal sizes. Any additional hyperscaler or sovereign-AI wins would extend the ≈$46B backlog and trigger further analyst target upgrades.


🎲 4-Reader Interpretation

🚀 YOLO Trader

This trade isn't for you to copy directly — selling naked calls is one of the riskiest plays in options (theoretically unlimited loss if NBIS goes to $500). But there's a flip side: if you're bullish on NBIS and you think it clears $300 by January, you can BUY the same NBIS Jan-2027 $300C that this seller just collected $71.25 for. You'd pay $71.25 per share (≈$7,125 per contract). NBIS needs to clear ≈$371 at expiry for you to break even — a 42% move from here. High risk, high reward, and you need the AI capex cycle to keep ripping through January. The quarterly implied move to $409 puts that in the probability cone, but it's far from guaranteed.

📊 Swing Trader

The $280 gamma wall (the prior all-time high) is your near-term ceiling to watch. If NBIS reclaims and holds above $280, the mechanical resistance there clears and the path to $300 opens up. A near-term swing: watch for confirmation above $265-$270 first (lighter overhead gamma), then assess momentum into earnings (late July/August). The $250 level is your line in the sand — a close below $250 removes the key put-gamma support and opens the door to $240. The earnings print is a binary event; trim exposure into it, not through it.

🛡️ Premium Collector

This is your trade in spirit. The seller collected $71.25 on the $300 call — an extraordinarily high premium for an ≈18% OTM strike. If you own NBIS stock and want to run the same overwrite strategy at a smaller scale: the $280 or $290 strikes for August or October expiry are the natural levels to sell against. You give up upside above your strike but collect meaningful premium given NBIS's elevated IV. The risk: if NBIS rips through $280 on a massive Q2 earnings beat, you get capped. Size the overwrite conservatively — maybe 20-30% of your position — so you still participate in a continued rally.

🌱 Entry-Level / Beginner

Here is the plain-English translation: someone who likely owns a lot of NBIS stock (or NBIS call options) just got paid $14M to accept a ceiling. They said: "I'll give up any profits above $300 per share by January 2027, in exchange for $14M right now." Think of it like a landlord renting out an option to buy their house at $300 — the tenant pays $14M rent upfront. If the house never hits $300, the landlord keeps the $14M and still owns the house. If it hits $300, the landlord has to sell at that price (but they've already made $14M plus the gain from wherever they bought). This strategy is called a covered call overwrite and it's one of the most common ways big institutions generate income on stocks they already own. The risk is that NBIS does actually go above $300 — and then the seller misses out on additional gains above that level.


⚠️ Risk Factors

Options trading involves substantial risk. Here are the specific risks for this trade and for NBIS broadly:

This Call Sale Could Be Very Poorly Timed The $300 strike sits inside the monthly implied move upper range ($344.22). If Nebius delivers another blowout quarter in August or announces another hyperscaler deal, the stock could rip through $300 and keep going. The seller would be forced to cover or deliver shares at $300 — capping gains at exactly the wrong moment. NBIS has already moved ≈12% in a single session today.

The Bottom Line Is Still Loss-Making Adjusted net loss was $100.3M in Q1 2026 — GAAP net income included ≈$621M from non-cash/non-operating items. The business is investing massively and burning cash at the operating level. A $20-25B CapEx plan against ≈$9.3B in cash means heavy debt and potential equity dilution ahead, including a possible 25M-share ATM program.

Customer Concentration — Two Counterparties Control ≈$46B of Backlog Microsoft + Meta dominate the contracted revenue pipeline. Any renegotiation, delivery slip, or hyperscaler decision to insource GPU capacity would be a material negative for the stock — and for a short-call holder, that kind of de-rating would only be partially offset by the premium collected.

Valuation Has Outrun the Street Per Foreign Policy Journal's analysis (June 5, 2026) and Simply Wall St, fair value models have whipsawed dramatically. The consensus PT of ≈$244 from Benzinga's tracker now sits below the current price — meaning if the Street is right, the stock should pull back, not rally to $300.

Insider Selling Has Been Persistent Analysts have flagged persistent insider selling alongside the YTD run-up — a yellow flag for anyone considering aggressive long positioning.

NVIDIA / Supply Dependency The entire Nebius thesis is predicated on NVIDIA delivering Vera Rubin NVL72 at scale and on time. Any NVIDIA supply chain disruption or next-generation chip delay would ripple through Nebius's capacity commitments and backlog delivery dates.

What the OPRA Tape CANNOT Tell Us: We know the mechanism (single-leg block cross), size (2,000 contracts), price ($71.25), and direction (SELL, credit). We do NOT know the seller's identity, whether they own the underlying stock (making this a covered call vs. a naked short), their existing portfolio context, their cost basis, or their stop-out level. We interpret the tape; we don't read minds.


🎯 The Bottom Line

Here's the deal: a desk just collected ≈$14M in premium by selling the January 2027 $300 LEAP call on Nebius Group — a stock trading ≈$261 after running ≈175% YTD.

The most logical read is an overwrite / premium collection strategy: a sophisticated holder, sitting on massive NBIS gains, sold upside at a strike (≈18% above spot) that the Street doesn't believe in (consensus PT ≈$244 is below today's price), while collecting $71.25 of elevated implied volatility premium. Whether it's an opening short or a long-call holder cashing out, the economics are attractive for the seller today.

But we are provisional on this. Size (2,000) is below prior OI (8,100). Come back tomorrow morning at ≈06:30 ET for the OPRA overnight OI update — that resolves the open vs. close question definitively.

What to watch:

  • 📅 Tomorrow ≈06:30 ET: OPRA OI snapshot — OI up ≈2,000 = new opening short; OI down ≈2,000 = long-holder closing
  • 📅 This week (June 18-19): NBIS is heading into a triple witch expiration. Weekly implied move is ±11.65% (range $230.42–$291.22) — expect elevated volatility
  • 📅 Late July / mid-August 2026: Q2 2026 earnings — the biggest binary event before the January 2027 expiry. An upside surprise could threaten the $300 seller's cap; a miss is the seller's best friend
  • 📅 2026 CapEx pacing and Vera Rubin delivery news: each capacity milestone is a discrete catalyst
  • 📅 January 15, 2027: NBIS Jan-2027 $300C expiration — the moment of truth

If you own NBIS stock: The $280 gamma wall (prior all-time high zone) is your near-term upside target to watch. The $250 put-gamma support level is your line in the sand to the downside. The overwrite strategy embodied in this trade is worth considering if you have a large NBIS position and want to collect premium while waiting for Q2 earnings.

If you're watching from the sidelines: The ≈12% intraday move today suggests elevated single-session volatility. The $250 level on a pullback offers a better entry against gamma support than chasing the rally at $261. Earnings in late July/August is the key catalyst to position for.

If you're bearish: The $280 gamma wall is the natural level where upward momentum slows mechanically. A failure to hold above $261 on a close basis would be a near-term technical negative.

A ≈$14M LEAP call sale at the $300 gamma wall, against a stock up ≈175% YTD with a consensus PT below the current price — methodical, patient, and premium-driven. The thesis is: "I've already made a lot. Let me take some off the top."
