Six layers

Most pure BCI companies are private; listed names carry BCI as a small part of their business.

Implants (the platforms)

Bullish · 60%

WETWIRED view: Capital, approvals and trial results are all accelerating. But the best risk/reward is in names approaching approval (Science, Synchron) rather than the most famous one.

Tickers, exposure, catalysts & risks
Public
Private
Neuralink, Synchron, Precision, Paradromics, Science Corp., Blackrock (majority-owned by Tether), Neuracle (pre-IPO, China).
Exposure
Secondary markets for accredited investors (Nasdaq Private Market, Forge, EquityZen, Hiive), usually via SPVs with fees. ARK Venture Fund added Neuralink in Q2 2025. ONWD is the one listed implant maker. Nasdaq Private Market, 2 Oct 2026 ARK Venture Fund, Q2 2025 update
Catalysts
Risks
No brain-implanted BCI is approved in the US. Prices run far ahead of patients (Neuralink ~$42B on secondaries vs 21 published participants). Reimbursement is untested outside China. Access is illiquid and accredited-only. Business Insider, Jul 2026 Neuralink, 27 Jan 2026
Where this goes
Neural lace (The Culture) and the VISOR (Star Trek). Whole-brain bandwidth and artificial sight. Today: 11.32 bits/sec, and the first retinal implant on sale in Europe. Neuralink, 1 Oct 2026 Science Corp., 5 Oct 2026

Surgical robotics & delivery

Neutral · 55%

WETWIRED view: Real need, but no listed company sells BCI surgery as its main business.

Tickers, exposure, catalysts & risks
Public
Private
Neuralink (in-house R1 robot). Most BCI makers build or borrow their own surgical tools.
Exposure
CLPT is the closest listed pick-and-shovel. In MDT the exposure is a rounding error. ClearPoint Neuro, Jul 2021
Catalysts
Risks
CLPT trades on gene-therapy partners, not BCI: it fell 24% on 29 Sep 2026 after uniQure's AMT-130 update, and law firms have opened investor investigations. BCI makers keep robots in-house, so there is no merchant market yet. Yahoo Finance, 29 Sep 2026
Where this goes
The ripperdoc (Cyberpunk 2077). Implant surgery as a routine, automated service. Today: Neuralink's in-house robot and a promise of "almost entirely automated" surgery in 2026. Neuralink: technology Reuters, 1 Jan 2026

Electrodes & materials

Neutral · 50%

WETWIRED view: The right layer, the wrong vehicles: the best electrode makers are private.

Tickers, exposure, catalysts & risks
Public
Private
Blackrock Neurotech (the Utah array used in most academic BCIs), Precision (thin-film Layer 7), Paradromics, Merge Labs (gene therapy + ultrasound).
Exposure
Microcaps (NMTC, BFLY) or private rounds. Blackrock is controlled by Tether and not open to outside investors. Reuters, Apr 2024
Catalysts
Risks
Microcap dilution, tiny revenue, and single-customer dependence (BFLY on Merge Labs). Butterfly Network IR, Sep 2026
Where this goes
Neural lace (Iain M. Banks). A fine mesh that grows into the brain. Today: thin-film arrays and polymer threads; sheep recordings stable for 4 years. Frontiers in Neuroscience, 2022 Business Wire, 8 Oct 2026

Chips & signal processing

Neutral · 60%

WETWIRED view: Watch it, don't buy it for BCI.

Tickers, exposure, catalysts & risks
Public
Private
Neuralink designs its own implant chip. Every major BCI maker does the same.
Exposure
None pure-play. BCI is a rounding error for any listed chipmaker. Business Wire, Mar 2025
Catalysts
Risks
There is no merchant market for BCI chips; implant makers keep them in-house. Neuralink: technology
Where this goes
The cyberbrain (Ghost in the Shell). Silicon that sits inside the skull. Today: Neuralink's coin-sized wireless implant with custom electronics. Neuralink: technology

Neural data & AI software

Bullish · 55%

WETWIRED view: The fastest-improving layer: performance is software-limited, so gains compound with every patient-hour.

Tickers, exposure, catalysts & risks
Public
Private
Neuralink (decoders, 11.32 bits/sec record), Synchron (Chiral), Paradromics (real-time speech).
Exposure
Indirect only: via the implant makers, or via compute. Neuralink, 1 Oct 2026
Catalysts
Risks
Neural-data privacy rules could tighten. Decoders are only as good as each company's patient count.
Where this goes
The cortical stack (Altered Carbon). The mind as data. Today: Neuralink pretrains decoders on 50,000 hours of brain recordings, and one speech-BCI user has said ~2M words. Neuralink, 1 Oct 2026 Science News, 15 Oct 2026

Rehab & non-invasive

Bullish · 60%

WETWIRED view: Revenue now, not in 2030. The nearest thing to an investable BCI-adjacent business today.

Tickers, exposure, catalysts & risks
Public
Private
BrainCo (China, filed for a Hong Kong IPO in Jan 2026), Kernel.
Exposure
Listed stocks. The only BCI-adjacent layer with product revenue today. ONWARD H1 2026 release
Catalysts
Risks
Small revenue bases; ONWARD is loss-making and raised €40.6M in H1 2026. NXL is a volatile microcap. ONWARD H1 2026 release CNBC quote page
Where this goes
Jarvis (Iron Man). Control by intention, no surgery. Today: Meta's EMG wristband ships with its display glasses. Meta, Sep 2025
  1. Money is ahead of patients. Neuralink went from a $9B round (Jun 2025) to about $42B on secondaries (Jul 2026). Its published count has been 21 since January. Neuralink, Series E, Jun 2025 Business Insider, Jul 2026 Neuralink, 27 Jan 2026
  2. Eyes before brains. The first FDA approval of an implanted BCI looks likely to be a retinal implant, not a brain one. Science Corp., 5 Oct 2026
  3. China sets the regulatory pace. China approved the first implanted BCI, issued an insurance code within 48 hours, and has an IPO queue forming (Neuracle; BrainCo filed in Hong Kong). Bird & Bird, 2026 36Kr, 11 Jun 2026 Wikipedia: BrainCo (Bloomberg, Jan 2026)
  4. Speech is the killer app. One man has said about 2M words through a speech BCI. Neuralink (VOICE trial) and Paradromics both showed speech in Sep 2026. Science News, 15 Oct 2026 Neuralink on X, 18 Sep 2026 Business Wire, 14 Sep 2026
  5. The Musk stack is converging. xAI was folded into SpaceX, SpaceX and Tesla share the Terafab chip plant, and a merger is on the table. Neuralink is the one big Musk asset still outside the stack. Wikipedia: SpaceXAI (xAI deal, Feb 2026) Wikipedia: SpaceX (IPO, Terafab) Yahoo Finance, 16 Oct 2026 (Barclays note)

Ticker check: how real is the exposure?

Private leaders and how people get exposure

Neuralink, Precision, Synchron, Science and more

speculation The Musk convergence

Facts: xAI became a SpaceX subsidiary in Feb 2026 Wikipedia: SpaceXAI (xAI deal, Feb 2026). SpaceX listed on Nasdaq as SPCX in Jun 2026, and SpaceX and Tesla are building the Terafab chip plant together Wikipedia: SpaceX (IPO, Terafab). Barclays now calls a Tesla–SpaceX tie-up the consensus expectation Yahoo Finance, 16 Oct 2026 (Barclays note). Neuralink is the one big Musk company still outside that stack, valued at about $42B on secondaries Business Insider, Jul 2026.

WETWIRED's view: if Tesla and SpaceX combine, robots (Optimus), AI (Grok) and chips (Terafab) sit under one roof. A brain interface is the obvious missing input device, and that is the bull case for Neuralink joining later. We put that at 20% by end-2027 (F4). Today, buying TSLA or SPCX buys no Neuralink.
