Owned by the commons, extracting from no one. The largest gain isn't a faster trade — it's the rail beneath it: atomic settlement that dissolves post-trade fragmentation, corporate actions and disclosure built in, and fair markets where speed buys no advantage. Public infrastructure for the whole life of equity — with the fairness layer proven, not asserted.
Financial-market infrastructure is a rent-extracting natural monopoly — and below IPO scale, most of the economy has no rail at all.
Exchanges, clearing houses, and data vendors enjoy network effects and near-zero marginal cost — and monetize that position hard.
Below IPO scale, 99% of companies can't access listed equity. Raising is bespoke and illiquid; private shares and employee stakes have nowhere to live.
Continuous trading hands a structural edge to the fastest, and a single trade can paint the price. The same shares trade at different prices in the same instant.
NYSE, Nasdaq, and state-backed exchanges are all tokenizing equity now. We can't win on the technology — and we don't try to. Every one of them is a for-profit vendor, and a vendor can only ever be one option among many. It can never become infrastructure a regulator mandates or a public programme funds, because that would be picking a private winner.
A credibly-neutral commons can be mandated, subsidized, and built upon. The ownership model isn't a constraint on adoption — it is the strategy.
Live proof, 2026. As SpaceX and OpenAI line up to go public, Nasdaq rewrote its index rules weeks before the listing — the press dubbed it "Lex SpaceX" — while retail demand for the private shares routed through SPVs charging ~4% up front + 25% of profits, and vehicles trading at a ~3,000% premium. A for-profit venue can rewrite the market's rules to land a whale; a commons structurally cannot. Capillary wouldn't host these names — it removes the pattern for the markets it serves.
From a single community project to a graduated public company — four pillars, plain and real.
One neutral rail for cap table, dividends, votes, and transfers. Cheap, real, low-regulatory — the wedge that lands issuers.
The wedgeFrequent batch auctions instead of continuous trading: one uniform clearing price per interval, so speed confers no advantage and prices can't be painted with a single trade.
Speed-neutralA per-issuer automated market maker guarantees every holder a counterparty from day one — so a thin-name market isn't dead on arrival.
Liquidity from day oneCryptographically-verified, equal-access corporate disclosure — the consolidated data layer Europe lacks, by construction.
Equal accessWe built an open, reproducible market-mechanism simulator — 57 unit tests, validated against textbook competitive-equilibrium theory, regenerated with one command (python -m sim.reproduce). Every figure below traces to results/; none is rounded or embellished.
One fair price for everyone, set by supply and demand — not by who was fastest.
The same orders arrive in sequence and match at scattered prices.
Captures all available gains-from-trade at every liquidity level, across 800 random markets. Continuous trading loses ~20% — even with fully honest traders.
results/validation.txt · experiment.txtModelled sniping profit under batching is exactly 0 at every news volatility. Run through a real latency race, the sniper profits in continuous time — and 0 when batched, no matter how fast it races.
results/sniping.txtThere is no per-trade price to paint: the reference stays at ~100 while a continuous book prints a fake 130. Pegging the price gets ~linearly costlier as liquidity grows.

The neutral protocol and treasury — uncapturable and purpose-bound. It guards a security-budget floor so the one real risk, under-funding, can't bite.
Bicameral and identity-weighted across issuers and investors, with no capital-weighted capture. Policy is set by the people who use the rail.
For-profit service providers compete where competition belongs — at the service edges, on top of the neutral core. Not for the core itself.
The commons funds itself with a flat per-transaction toll, capped to the treasury's needs, with surplus rebated to participants. Because the payers are the governors, it can't drift into rent.
Grant and blended finance lead the build — the core is never funded by a returns-seeker, so it is never owned by one.
Europe's capital-markets problem is structural, not a matter of efficiency. The DLT Pilot Regime proved that tokenized shares mean nothing if they ride the same rails under the same rules.
Capillary is the credibly-neutral commons the Draghi report, the Savings and Investments Union, and the ECB's sovereignty agenda keep describing. We lead with the neutral public post-trade rail: atomic settlement that dissolves fragmentation, programmable corporate actions, and a native transparency layer — integrated with ECB central-bank-money settlement, not competing with it.
The credibly-neutral commons the SIU, the single-CSD agenda, and ECB autonomy keep calling for — that a for-profit vendor can never become.
