Inside FSKAX: The Top 15 and the AI Trade

A company-by-company read of the 15 largest FSKAX holdings from their most recent quarterly reports: how profitable they are, why, their position in AI and chips, whether AI is paying off yet, and their exposure to the data-center buildout now facing its first US permitting moratorium.

Why this analysis exists

FSKAX is marketed as owning the whole US market, but it is market-cap weighted, so a handful of names dominate it. These top 15 companies are ~39.7% of the entire fund, and roughly 34.4% of the fund sits in AI-exposed names (about 27.2% in the AI/chip core). That means FSKAX is, to a first approximation, a leveraged bet on the artificial-intelligence capital-expenditure cycle. The purpose here is to pressure-test that bet at the company level and answer one question directly: what happens to these holdings if the AI trade re-concentrates in a few winners, or if the data-center buildout that underwrites it slows - a risk that just became concrete when New York imposed the first statewide moratorium on hyperscale data centers on July 14, 2026.

Takeaways first

  1. FSKAX is an AI-capex fund in disguise. ~39.7% of the fund is these 15 names and ~34.4% is AI-exposed. When people say they own "the total market," most of the money is really riding on this one theme.
  2. The buildout is still accelerating, not slowing. Every hyperscaler raised 2026 capital-expenditure guidance - Microsoft ~$190B, Amazon ~$200B, Alphabet $180-190B, Meta $125-145B - and all describe themselves as capacity-constrained. NVIDIA guided to $91B of revenue next quarter. As of these reports there is no visible slowdown.
  3. But the whole chain leans on a handful of buyers. NVIDIA books ~54% of revenue from three customers; Broadcom depends on six custom-silicon customers; AMD's and Micron's growth rides on the same names (Meta, OpenAI, Oracle, Microsoft, Amazon, Google). This is exactly the "re-concentration" risk you flagged - and it cuts both ways.
  4. Profits are real, and mostly concentrated in a few segments. The money is made in cloud (AWS ~$14.2B of Amazon's operating income; Azure +40%), advertising (Google Services, Meta Family of Apps), and now memory (Micron). Several names carry margins at or near historic peaks.
  5. The moratorium is a leading signal, not yet an earnings hit. None of the megacaps disclose a New York hyperscale project; flagship builds are in Ohio, Louisiana, Wyoming and Texas. So NY reads as an early warning of Northeast and potentially spreading permitting risk, rather than a present dent in results. One name, ExxonMobil, is positioned to benefit from data-center power demand.
  6. Watch the memory cycle. Micron's ~85% gross margin is historically extraordinary and, on any prior pattern, a cycle-peak marker. Peak margins in a deeply cyclical business are a reward and a warning at the same time.

Scorecard: the top 15 at a glance

Ordered by weight in FSKAX (Alphabet's two share classes consolidated). "Rating" is exposure to the data-center buildout and the moratorium wave.

6.96% of FSKAXDemand-levered
AI/chip core  ·  Latest report: Fiscal Q1 FY2027 (ended Apr 26, 2026, released May 20, 2026)
Profitability

Revenue $81.6B, +85% YoY. GAAP net income $58.3B; operating income $53.5B. Gross margin 74.9%, operating margin ~65.6%, net margin ~71.4%. No China H20 charge this quarter; Q2 guide assumes zero China data-center compute.

Why profitable

Data Center revenue $75.2B, +92% YoY = ~92% of total; within it, compute $60.4B (+77%) on the Blackwell 300 ramp plus InfiniBand / Spectrum-X / NVLink networking. Edge Computing (gaming, pro-viz, auto) $6.4B (+29%). The moat is the CUDA software ecosystem plus a full rack-scale system.

AI & chip outlook

Q2 FY2027 guide: revenue $91.0B ±2%, gross margin ~74.9%. Blackwell shipping at scale with 'extended' lead times; Vera Rubin begins shipping fiscal Q3 FY2027. CEO Huang calls the AI-factory buildout 'the largest infrastructure expansion in human history.'

Is AI paying off?

NVIDIA's revenue is everyone else's AI capex, so it is the purest read on the trade. Hyperscalers are ~50% of data-center revenue (~$37.9B, +115% YoY). Concentration risk (10-Q): three direct customers = 21%, 17%, 16% of revenue (~54% combined). If the buildout pauses, the hit is fast and concentrated here.

Data center & moratorium risk

A leveraged bet on continued data-center construction. NY's July 14, 2026 moratorium on facilities ≥50 MW, plus any spreading permit-pause trend, would lengthen already-extended lead times and could turn deferrals into cancellations. NVIDIA discloses no state-level exposure (UNCONFIRMED), and its forward guide is still accelerating, so no slowdown is visible yet.

Profitability

Revenue $109.9B, +22% YoY. Operating income $39.7B; operating margin 36.1%. Net income $62.6B, +81% (boosted by ~$36.9B of pretax equity-security gains, so operating income is the cleaner read). Google Cloud $20.0B, +63%; Cloud operating margin 32.9% (vs 17.8% a year ago).

Why profitable

Search advertising is the engine: Google Services revenue $89.6B (+16%), segment operating income $40.6B (Search & other $60.4B +19%; YouTube ads $9.9B +11%). Cloud is the second lever, with operating income tripling year over year.

AI & chip outlook

8th-generation TPU (TPU 8t = 3x the processing of 7th-gen Ironwood; TPU 8i = 80% better performance per dollar). Gemini 3.1 Pro; Gemma 4 downloaded 50M+ times. Will be among the first to offer NVIDIA's Vera Rubin NVL72. First-party models process 16B tokens/minute via API, up from 10B.

Is AI paying off?

Revenue from gen-AI products grew ~800% YoY; Cloud backlog ~$460B (more than doubled QoQ); Gemini Enterprise paid users +40% QoQ. Q1 capex $35.7B; full-year 2026 capex guidance raised to $180-190B, with 2027 to 'increase meaningfully.'

Data center & moratorium risk

Management said Cloud 'revenue would have been higher with more capacity' - a real near-term constraint. Specific data-center sites and any NY/Northeast projects are not disclosed (UNCONFIRMED). The $180-190B capex is a bet that demand keeps outrunning supply.

AI-exposed  ·  Latest report: Fiscal Q2 2026 (ended Mar 28, 2026, released Apr 30, 2026)
Profitability

Revenue $111.2B, +17% YoY. Net income $29.6B; EPS $2.01 (+22%). Operating margin 32.3%; gross margin 49.3%. Products gross margin 38.7% vs Services gross margin 76.7%.

Why profitable

iPhone leads the top line (March-quarter record $57.0B), but the margin engine is Services (76.7% gross margin): ~28% of revenue yet ~43% of gross profit. The moat is pricing power over a locked-in installed base.

AI & chip outlook

Apple runs its AI servers on its own Apple Silicon (not NVIDIA/AMD) for Private Cloud Compute. Apple Intelligence is now active on 80%+ of eligible devices; a ~$1B Google Gemini deal will power a revamped Siri targeting a fall iOS 19 launch. R&D jumped ~34% YoY to $11.4B.

Is AI paying off?

No standalone AI revenue line; management frames AI as 'incremental' spend, not a separate P&L. Capex stays light at ~$14.3B for 2026 (estimate) versus the five hyperscalers' collective ~$660-690B. Monetization is indirect (device upgrades, Services attach) and not yet separately quantified (UNCONFIRMED).

Data center & moratorium risk

Not materially relevant. Apple runs limited first-party data centers and buys partner GPU capacity rather than building ≥50 MW campuses, so NY's moratorium does not target its footprint. Any exposure is indirect (partner-hosted compute cost/latency). UNCONFIRMED that Apple has any ≥50 MW NY project.

Why profitable

Two engines: Productivity & Business Processes $35.0B (+17%, Microsoft 365 Commercial Cloud +19%) and Intelligent Cloud $34.7B (+30%, Azure the driver). More Personal Computing $13.2B (-1%) is the soft spot.

AI & chip outlook

AI business run rate reached $37B annualized, +123% YoY. Custom silicon (Maia 200, Cobalt) is deployed; added ~1 GW of capacity in the quarter. Multi-model strategy (OpenAI + Anthropic usage doubled QoQ). Explicitly 'capacity-constrained through 2026.'

Is AI paying off?

Signal: $37B AI run rate and Azure +40% (above ~35% consensus). Cost: capex plus finance leases $31.9B, +49% YoY; forward guidance >$40B next quarter and ~$190B for calendar 2026 (+~61%, including ~$25B from higher memory pricing). Management frames the assets as supporting 'monetization over the next 15 years.'

Data center & moratorium risk

~$190B of 2026 capex with no pullback; a Cheyenne, Wyoming expansion was announced in April. No Microsoft-owned NY hyperscale project is disclosed (the flagged Somerset, NY site belongs to TeraWulf, not Microsoft), so direct NY exposure is limited (UNCONFIRMED); the moratorium reads as a broader Northeast permitting-risk signal.

Profitability

Net sales $181.5B, +17% YoY. Operating income $23.9B (13.1% margin, a record). Net income $30.3B includes a $16.8B non-cash Anthropic gain, so operating income is the truer read. AWS $37.6B (+28%, fastest in 15 quarters); AWS operating income $14.2B, ~37.8% margin.

Why profitable

AWS produced $14.2B of the $23.9B total operating income (~59%) on just 21% of sales. Retail runs thin (North America ~8% margin, International ~3.5%). AWS is the profit engine.

AI & chip outlook

Amazon's chip business is now a >$20B revenue run rate, growing triple digits; Trainium2 is fully committed and Trainium3 nearly subscribed. It is also deploying 1M+ NVIDIA GPUs (dual-chip strategy). Bedrock customer spend +170% QoQ; a new Anthropic deal is worth >$100B.

Is AI paying off?

AWS AI revenue run rate >$15B in ~3 years. Q1 capex ~$43-44B (single-quarter figure varies by source, UNCONFIRMED); full-year 2026 capex ~$200B (CEO commentary, not formal guidance). ROI language: 'customer commitments for a substantial portion.' Backlog $364B.

Data center & moratorium risk

~$200B of 2026 capex aimed mostly at AWS AI data centers, with growth 'limited by power' and memory costs that 'skyrocketed.' No AWS NY/Northeast project was disclosed (direct exposure UNCONFIRMED); NY's queue held ~25 proposals totaling ~9,340 MW when the moratorium landed.

Why profitable

A dual engine: Semiconductor Solutions $15.0B (68% of revenue, custom AI silicon + networking) and high-margin, recurring Infrastructure Software / VMware $7.2B (32%).

AI & chip outlook

AI semiconductor revenue $10.8B, +143% YoY from custom accelerators (XPUs) and AI networking. Six core custom-silicon customers, named to include Anthropic, Google, Meta and OpenAI. Tomahawk 6 (100-terabit) switch shipping; Jericho fabric. Q3 guide: total ~$29.4B (+84%), AI semi $16.0B (>200% YoY).

Is AI paying off?

AI is ~49% of revenue and climbing fast (Q1 $8.4B to Q2 $10.8B to Q3 guide $16.0B). CEO Hock Tan reiterated AI semiconductor revenue 'in excess of $100 billion in fiscal 2027.'

Data center & moratorium risk

XPU and networking demand is a derivative of hyperscaler buildout, and the six-customer concentration means a pullback by even one large buyer is material. NY's moratorium plus a possible multi-state trend could defer ≥50 MW capacity; Broadcom gave no moratorium-related guidance cut, and magnitude of any exposure is UNCONFIRMED.

Why profitable

The profit lever was automotive gross-margin recovery (16.2% to 21.1%), plus high-margin energy storage (~39.5%) and +42% services. Pressure points: operating expense +37% YoY (AI/R&D and stock comp), regulatory credits down ~36%, storage revenue -12%. Underlying auto strength (19.2% ex-credits) is real.

AI & chip outlook

In-house training clusters Cortex 1 (>100k H100-equivalent) and Cortex 2 (>130k, ramping). FSD approved in the Netherlands; Robotaxi launched in Dallas/Houston in April 2026. The AI5 inference chip taped out April 15, 2026 (~5x AI4, volume 2027); Tesla is adding in-house semiconductor fabrication. Optimus targets volume production in 2026.

Is AI paying off?

Not materially yet. Robotaxi is in limited early operation and FSD revenue is small against the spend; 2026 capex is guided >$25B. Management frames AI, Robotaxi and Optimus as future engines, not current earnings drivers. (Q1 free cash flow was +$1.44B per the SEC filing.)

Data center & moratorium risk

Tesla's compute (Cortex 1 and 2) sits at Giga Texas, a captive AI cluster rather than a merchant data center, and NY's ≥50 MW moratorium targets utility-interconnected facilities. Not materially relevant on the current footprint; a broad multi-state wave is a future siting watch-item (UNCONFIRMED, no NY plans disclosed).

Profitability

Revenue $41.46B, +346% YoY (beat $35.82B consensus). GAAP net income $28.2B; EPS $24.67. Non-GAAP gross margin 84.9%, a record, up from 39.0%. Analyst caveat: ~85% gross margin is historically extraordinary for a memory maker (prior peaks ~45-60%); this is cycle-peak territory, and memory is deeply cyclical, so peak margins carry peak-cycle downside risk.

Why profitable

Pricing and mix in an AI-memory super-cycle. Segment gross margins: Cloud Memory 83%, Core Data Center 87%, Mobile & Client 87%, Auto & Embedded 79%. HBM4 (High Bandwidth Memory) is shipping >$1B and ramping ~2x the pace of HBM3E.

AI & chip outlook

HBM3E and HBM4 are fully booked through calendar 2027, with demand extending into 2028 and HBM4E already oversubscribed. Management sees the HBM total addressable market 'easily crossing $100B in 2027.' Q4 FY2026 guide: revenue $50.0B ±$1.0B, gross margin ~86%.

Is AI paying off?

Decisively yes: data-center revenue ~$25.3B (~61% of total), enterprise SSD ~$5B, and demand 'far above supply.' Q3 net capex $7.1B; adjusted free cash flow $18.3B.

Data center & moratorium risk

The ~61% data-center concentration makes Micron directly geared to the buildout, so a broad slowdown would eventually soften HBM pricing. Near-term insulation is real: HBM is contractually sold out through 2027. Note the NY tie-in: Micron's Clay, NY megafab (up to four DRAM fabs, ground broken January 2026) is semiconductor manufacturing, not data-center load, so the ≥50 MW data-center moratorium does not directly restrict it (analysis, UNCONFIRMED). The real exposure is demand-side, post-2027.

Scale plus grocery-led traffic (Walmart US comps +4.1%) funding a shift to higher-margin income: advertising +37% (Walmart Connect), marketplace ads +50%, and membership fees +17.4% - all growing far faster than the ~7% top line.

AI angle

AI angle: Walmart is deploying AI across the supply chain, associate tools, and a shopping agent ('Sparky') credited with digital growth. No AI revenue is broken out; it functions as a margin and productivity lever, not yet financially material (UNCONFIRMED).

Profitability

Revenue $10.25B, +38% YoY. GAAP gross margin 53%, operating income $1.48B (+83%), net income $1.38B (+95%), EPS $0.84 (non-GAAP $1.37). Data Center revenue $5.78B (+57%), segment operating income $1.60B (~27.7% margin).

Why profitable

Data Center is now the engine (56% of revenue, ~64% of segment operating income), driven by EPYC server CPUs and ramping Instinct GPUs. CEO Lisa Su: 'Data Center now the primary driver of our revenue and earnings growth.'

AI & chip outlook

Instinct MI355X posted leadership MLPerf results; the MI400 series launched (MI455X: 432 GB HBM4, up to 40 PFLOPS FP4), with the Helios rack shipping in 2026. ROCm 7.x is the open answer to NVIDIA's CUDA but still narrower. Named commitments: Meta up to 6 GW, OpenAI 6 GW, Oracle ~50,000 MI450.

Is AI paying off?

Yes and accelerating: Q2 2026 guide ~$11.2B (~46% YoY). Su guided a path to 'tens of billions of dollars in annual Data Center AI revenue in 2027.' NVIDIA still holds the software-ecosystem lead.

Data center & moratorium risk

Direct NY exposure is modest, but Instinct/EPYC demand rides on a few hyperscalers (Meta, OpenAI, Oracle, Microsoft), so multi-GW slips at any one materially move Data Center revenue. The real risk is a spreading permit-pause slowing the power-and-siting pipeline that gates GW-scale deployments (NY-specific exposure UNCONFIRMED).

What it means for the FSKAX holder

Putting the 15 together, the picture is coherent and a little unnerving. The profits are genuine and, right now, growing fast: cloud, advertising, and memory are throwing off record operating income, and every builder is spending into the demand rather than pulling back. If you own FSKAX, that engine has been carrying your returns.

The fragility is that the engine has very few moving parts. The same six or so hyperscalers are simultaneously the customers of NVIDIA, Broadcom, AMD and Micron and the builders whose capex is the demand. If AI spending re-concentrates in the strongest one or two players, the arms suppliers with customer concentration (NVIDIA, Broadcom, AMD, Micron) feel it first and hardest, while the surviving hyperscalers may actually strengthen. That is why "re-concentration" is not simply bad for FSKAX; it reshuffles which of these 15 win, and FSKAX owns them in cap-weighted proportion, so the mega-caps that win would still dominate your result.

The data-center moratorium is the cleanest early-warning variable to watch. Today it is one state and no megacap discloses a New York project, so it is not in the numbers. But it is the first physical constraint - power and permits - on a buildout that has so far been limited only by chips and money. If the pause spreads, the transmission runs demand-side: slower campus energization, then softer chip and memory orders, then the cyclical names (Micron especially, once its 2027 HBM bookings roll off) feeling it before the advertising and software engines do. The counter-position is ExxonMobil, which profits precisely because that power constraint is real.

Bottom line: FSKAX gives you the AI winners and the AI risk in one wrapper, weighted toward the biggest builders. The buildout is still accelerating, so the thesis is intact today; the things that would break it are customer re-concentration and a spreading power/permit constraint, both of which are now observable rather than hypothetical. This is the same "what could reverse it" question from the small-cap analysis, viewed from the inside of the megacaps themselves.
