On time horizons

01Four numbers

30 days. 18 months. 7 years. 70 years.

Those are the native horizons of four operations I run at the same time. A prediction in the AI and crypto event space resolves in roughly 30 days. A systematic digital-asset strategy at Mythos converges over 12-18 months of trades. A parcel in an Earth Credits issuance produces a measurable change in ecological condition over a 7-year cycle.

Most people run all their work at a single horizon. Usually the quarterly horizon — codified for U.S. capital markets by SEC Form 10-Q in October 1970

. A reasonable choice for one kind of disclosure and a poisonous default for almost all others.

02The native horizon

The native horizon of a system is the smallest unit of time over which the system can produce evidence about itself. Below the native horizon, the system is producing noise about itself; above it, the system is reporting on a unit of work it has already finished.

A machine-learning model release runs at the order of weeks. A systematic trading strategy at the order of a year. An ecological restoration at the order of a decade. A population-level conservation outcome at the order of generations. Faster than the native horizon and the artifact is the wrong artifact: a wishlist instead of a release, drawdown variance instead of a strategy, weather instead of a restoration, births and deaths instead of a population.

The substrate determines the horizon. The horizon determines what counts as evidence.

03Compression

Most failures I have watched in the conservation-finance overlap are compression failures. A venture timeline is asked to bear an ecological one. A prediction market is asked to price a question whose answer takes longer to settle than the market does to clear. A 10-Q is asked to summarize a multi-year ecological trajectory in a single quarter's grid. Each compression converts evidence back into testimony, and not by accident: the longer the native horizon, the more brittle the compression.

The pricing rooms that have learned this — the rooms that price catastrophe bonds, sovereign duration, generational forestry — handle it the same way. They refuse to compress, and they price the refusal. A 30-year sovereign bond is not a stack of 1-year bonds. A multi-decade ecological instrument is not a stack of quarterly accruals. The native horizon is the product, not a constraint on it.
