Start with the fund almost no one outside the state has heard of. In 2010, North Dakota voters created the Legacy Fund by ballot initiative: 30% of all state tax revenue from oil and gas extraction, diverted automatically into a permanent, Norway-style sovereign wealth fund rather than spent as it came in.^[1] By September 2025, the fund had grown past $13 billion.^[2] North Dakota's population is roughly 780,000 -- which puts the fund at close to $16,700 for every resident of the state, sitting in reserve, earning returns, specifically insulated from the Bakken oil boom ever going bust the way boom-and-bust extraction economies usually do.^[1] Alaska is the sovereign-wealth-fund state most Americans can actually name. North Dakota built a comparable one and almost nobody outside the state knows it exists.

South Dakota's version of the same story is bigger, older, and more directly touches nearly every American who's never set foot in the state. In January 1980, the South Dakota legislature repealed its usury cap on interest rates -- proposed by a Sioux Falls banker after inflation had pushed market rates above the legal ceiling and was choking off local lending.^[3] On the last day of that same legislative session, at Governor Bill Janklow's own urging, the legislature passed a second bill specifically inviting Citibank to relocate to the state. In June 1981, Janklow and Citibank CEO Walter Wriston stood together in Sioux Falls for what the bank literally called "Citibank Day" -- and began exporting South Dakota's uncapped interest rates to credit-card holders nationwide through Citi's network.^[3] Delaware copied the move a year later, which is the actual reason most American credit card statements list a Sioux Falls or Wilmington address to this day -- the physical, literal proof of an obscure 1980 state law sitting in millions of Americans' wallets, entirely unremarked on.

That was the first deliberate act. The second, three years later, is even larger today. In 1983, South Dakota became the first state in the nation to abolish the Rule Against Perpetuities -- the centuries-old common-law limit on how long a trust could legally exist.^[4] Removing that limit made the modern "dynasty trust" possible: a trust that can hold assets in perpetuity, across unlimited generations, combined with South Dakota's total absence of state income tax, capital gains tax, or inheritance tax on trust assets.^[4] Wealthy families noticed. By 2025, assets held in South Dakota trusts topped **$906 billion** -- a $91 billion increase in a single year, and the highest figure in state history.^[5] South Dakota's population is about 919,000. That's roughly $985,000 in trust assets for every resident of the state -- not spread across residents, held on their behalf by a trust industry most of them will never personally touch, in a jurisdiction now ranked first in the country ahead of Delaware, Nevada, and Alaska.^[4]

Neither state stumbled into this. Both did it on purpose, more than once. North Dakota's Legacy Fund required voters to directly approve giving up 30% of a real, immediate revenue stream in exchange for a fund that wouldn't start paying out meaningfully for decades -- a genuinely difficult political choice, made anyway. South Dakota's two moves, three years apart, both followed the identical strategy: identify the single most restrictive rule standing between the state and a category of national capital, repeal it first, and let the capital follow. Nobody was covering either decision as it happened -- a state legislature repealing a usury cap and a state ballot initiative on oil tax allocation are not national news, even when the eventual consequence is $13 billion in one case and $906 billion in the other.

This is the coverage principle at its sharpest, dollar-denominated version: the same news cycle that generates ten duplicate stories about a single well-covered company generates zero stories about a state legislature quietly making itself the most attractive jurisdiction in the country for a specific kind of capital. North Dakota and South Dakota rank at the bottom of nearly every population and media-coverage list this site has built this year -- and simultaneously hold, combined, close to $920 billion in deliberately attracted capital. Both facts are true. Only one of them makes the news.
