The index itself
A curated 100-company index — Brain, Body (64 names), Integrators — pitched as one watchlist that spans the whole value chain. Pricing 4 Feb 2025.
Now a 255-name universe (150 core + 105 tier-2). All of MS's original 100 sit inside it — the cross-check shows 89 ms_h100 = yes after folding the 20 constituents v1 had missed. The other 166 are InfraMosaic's extension into the China component long-tail and rest-of-world supply chain. Total tracked cap $40.7tn, 255/255 live.
Executive thesis
Humanoids move from demo to deployment over the decade; a ~$5tn market by 2050, >1bn units by the 2040s. The supply chain — not the robot brands — is the durable trade, and it runs heavily through China. "52% of the Humanoid 100 already involved; 48% material potential."
The thesis aged well — and the boring half is exactly where value showed up. Brands still mostly pre-revenue; picks-and-shovels re-rated. Two things MS couldn't see now dominate:
1. Deployment is real — 26 programs in paid pilots/early production, 122,302 cumulative units on order or deployed.
2. A memory/AI-compute super-cycle repriced the Brain violently (NVIDIA $4.97tn, Micron $1.1tn).
Momentum & involvement
A near-vertical 2023–24 ramp in transcript and media mentions of "humanoid" — the attention leading indicator. Just over half of the 100 had confirmed involvement.
The mention curve climbed through 2025 then plateaued high — humanoids are a standing agenda item, not a novelty spike. Confirmed involvement (programs, supply contracts, named design-ins) is now the majority for core names; the "potential" bucket shrank as suppliers disclosed design-wins.
The Brain
Foundation models, AI compute, EDA, simulation, vision. US- and Taiwan-led: Alphabet, Microsoft, NVIDIA, TSMC, Arm, Cadence, Synopsys, Palantir, Oracle — with memory (Micron, SK Hynix, Samsung) as a footnote and vision (Hexagon).
Brain = 67 of 255; China 41.8% by count but value and moat sit in the US/Taiwan core. Most concentrated segment (HHI 3,232) — compute is an oligopoly. The 12 biggest names in the whole universe are now almost all Brain:
NVIDIA $4.97tn · Alphabet $4.39tn · Apple $4.28tn · Microsoft $2.90tn · Amazon $2.57tn · TSMC $2.20tn · Broadcom $1.82tn · Tesla $1.53tn · Meta $1.44tn · Samsung $1.40tn · Micron $1.11tn · SK Hynix $1.01tn
The Body
The Body (64 companies) is the electro-mechanical stack and where China has built an almost unassailable position. Parts walked one by one: bearings, screws, reducers, motors + rare-earth magnets, encoders, sensors, batteries, analog semis, structure. "Joint drive modules are 60–70% of a humanoid's cost."
Body = 147 of 255 (the universe's centre of gravity), China 41.5%, HHI 2,425. Every MS parts-bucket is now a value-chain node with a live exposure score and a supply/demand utilisation. The top of the exposure table is entirely Body:
| Rank | Company | IMES | Why |
|---|---|---|---|
| 1 | Harmonic Drive Systems | 92 | strain-wave reducer near-monopoly |
| 1 | Moog | 92 | precision actuation |
| 3 | Symbotic | 88 | warehouse automation pull |
| 4 | Renishaw | 85 | encoders / metrology |
| 5 | Nabtesco | 84 | cycloidal reducers |
| 5 | Intuitive Surgical | 84 | dexterous precision analog |
| 7 | UBTech | 83 | only listed pure-play maker |
| Part (MS Exhibit 14/15) | MS constituents | 2026 read |
|---|---|---|
| Bearings | NSK, RBC, Regal Rexnord, Schaeffler, Timken | commoditising; low IMES |
| Screws (ball + roller) | Hengli, Hiwin, NSK, SKF, Shanghai Beite, THK | deficit 770% tightest mechanical bottleneck |
| Reducers (harmonic + cycloidal) | Harmonic Drive, Nabtesco, LeaderDrive, Shuanghuan, Zhongda, Hiwin, Hota | highest-IMES node; China share climbing fast |
| Motors + magnets | Estun, Leadshine, Moons', Nidec, Inovance + JL Mag, Lynas, MP | magnets ~100% China; binding physical constraint (Dy/Tb controls) |
| Encoders | Nidec, Novanta, Sensata | Renishaw IMES 85; precision moat intact |
| Sensors — force/torque | Keli, Novanta, Sensata, TE | #1 BOM · 440% the re-write's hero chart |
| Vision / lidar | ADI, Hexagon, Keyence, Sony, Robosense, Aptiv, Magna, Valeo, Teledyne | glut 5.5% auto over-capacity spilled in |
| Batteries | CATL, EVE, LG ES, Samsung SDI | glut ~0% humanoid demand a rounding error on EV cells |
| Analog semis | Allegro, Infineon, Melexis, NXP, Onsemi, Renesas, ST, TI | steady; auto-cycle linked |
| Structure / wiring | Amphenol, Aptiv, Magna, TE, Xusheng, Sanhua, Tuopu | China die-casters scaling |
Integrators
Five archetypes: autos/OEM (BYD, GAC, Hyundai/Boston Dynamics, Tesla, Toyota, XPeng), tech/consumer (Apple, Foxconn, LG, Samsung, Sony, Xiaomi), cloud (Alibaba, Amazon, Naver, Tencent), industrial robotics (ABB, Midea/KUKA, Teradyne), pure-play (Rainbow Robotics, UBTech).
Integrators = 41 of 255, China 34.1%, least concentrated segment (HHI 2,064) — many credible assemblers, no winner yet. Pure-plays pulling ahead on shipped units: UBTech (Walker S2, 3-min battery-swap, >800m-yuan orders) and AgiBot/Zhiyuan (A2, #1 by 2025 volume, ~5,168 units) now out-ship Western brands.
Composition & regional
Humanoid-100 skewed China & Taiwan on the Body, US on the Brain. China = 63% of the supply chain (supply-chain-weighted). Analyst-surveyed AI-exposure / materiality / pricing-power scatter.
By name across 255: China 40.4% (103) · North America 24.3% (62) · Japan 14.5% (37) · Europe 7.8% (20) · Korea 5.9% (15) · Taiwan 4.3% (11) · Asia-other 2.4% · Oceania 0.4%. Country HHI 2,468. China-share by segment: Brain 41.8%, Body 41.5%, Integrator 34.1%.
Valuation & performance
P/E rank of the Humanoid 100, P/E vs 3-yr revenue CAGR, and LTM performance of the index and its Brain/Body/Integrator and regional sleeves vs benchmarks. Pricing 4 Feb 2025.
Since Feb 2025 the universe lived through an AI/memory super-cycle:
· NVIDIA $4.97tn, the gravitational centre.
· Micron $1.11tn (52-wk $103→$1,089) and SK Hynix $1.01tn (KRW 238k→2,407k) — memory went from footnote to two of the twelve biggest names.
· Total index cap $40.7tn; the top 12 alone ≈ $28tn.
Pop culture, pros/cons, TAM & hurdles
Humanoids general-purpose but expensive/immature vs purpose-built automation. ~$3tn US humanoid TAM by 2050 on labor-substitution; adoption negligible to ~2035 then an S-curve. Adoption hurdles listed.
The cost gap closed faster than the con-side assumed — the IHCI shows a Western reference robot down from ~$200k to ~$95k in 18 months. The market model keeps the same S-curve and brackets MS: base 550k units / $13bn (2030) → 1.4M / $30bn (2035). The 2028 inflection is intact; pilots are hundreds-to-thousands, not millions.
Hardware & bill of materials
Optimus Gen-2: 28 actuators (14 rotary + 14 linear), ~50 DoF, 22-DoF hand. Exhibit 54 BOM: Sensor 37%, Motor 20.3%, Screw 20.2%, Reducer 12.6%, Encoder 3.9%, FSD+chips+camera 3.8%, Bearing 0.8%, Battery 0.5%.
Reference BOM now re-based directly on Exhibit 54 (~$55,000): Sensors $20.4k (37%) · Motors $11.2k (20%) · Screws $11.1k (20%) · Reducers $6.9k (13%) · Encoders 4% · Compute 4%. Whole-robot curve: Western $200k (2024) → $40k (2030); China $46k → $18k. A regression test locks sensors as #1 so the correction can't silently revert.
Unveils tracker
~67 notable unveils since 2022; 2024 = 51 unveils (China 35, US 8, EMEA 4, Rest-Asia 4); China 61% of all unveils, US/Canada 24%. General-purpose 56% of use-cases.
Folded into a 58-program database with specs, status and pricing, carried forward through 2025–26. By region: China 32 · N. America 16 · Europe 4 · Japan 3 · Korea 1 · Middle East 1 · India 1. By maturity: Prototype 22 · Limited-prod 17 · Pilot 12 · Mass-prod 4 · Pre-prod 1. New: Unitree R1 ($5,800), 1X NEO ($20k), XPeng Iron, UBTech Walker S2, AgiBot A2, plus non-MS Humanoid / HMND 01 (London).
What's genuinely NEW since the paper
| New dataset | What it adds |
|---|---|
| Deployment tracker | 26 programs, 122,302 cumulative units in paid pilots/early production. In Feb 2025 there was essentially nothing to count — this is a whole new section on who is actually being paid to put robots on floors. |
| IHCI — InfraMosaic Humanoid Cost Index | Monthly, 2024-01 = 100. Now Western 47.3 / China 65.0 (Western reference robot down ~53% to ~$95k; China down ~35% to ~$30k). MS gave point estimates; InfraMosaic gives the track. |
| Supply / demand order book | Robot ramp × per-robot bill-of-quantities vs assessed capacity. 2030 verdicts — deficit roller screws 770%, F-T sensors 440%, integrated actuators 385%; glut LiDAR 5.5%, batteries ~0%, magnets 0.5%. Converts "China dominates the Body" into a quantified, node-by-node tightness map. |
Scorecard — right, wrong, couldn't know
| MS call | Verdict 2026 |
|---|---|
| "The supply chain, not the brands, is the trade" | ✅ Right — picks-and-shovels re-rated; brands still pre-revenue. |
| "China owns the Body / 63% of the supply chain" | ✅ Right & intensified — surgical dominance on magnets/reducers/screws + export controls. |
| "Sensors are 37% of BOM (Exhibit 54)" | ✅ Right in data, wrong in prose — narrative under-weighted its own number; now corrected & locked. |
| "$5tn by 2050 / S-curve from ~2028" | 🟡 Unfalsifiable but intact — near-term units now real and on-trajectory; long-run TAM still a guess. |
| "Joint modules = 60–70% of cost" | 🟠 Superseded — true at sub-system cut, misleading at component cut where sensors lead. |
| Memory as a Brain footnote | ❌ Missed — Micron & SK Hynix are now trillion-dollar index members. |
| No deployment / cost-track / order-book data | ⚪ Couldn't know — these are the 2026 additions, not MS errors. |
