In August 1976, a fund launched in Pennsylvania with the least ambitious pitch in the history of American finance. It would pick nothing. It would beat nobody. It would simply buy every large company in America in proportion to its size and then sit still, forever, collecting the average return. Jack Bogle hoped to raise $150 million for the First Index Investment Trust. He raised eleven, "an abject failure", by his own description. The industry called the idea un-American; the chairman of Fidelity scoffed that no investor would settle for merely average returns; the trade press named it "Bogle's folly," and the name stuck for a decade.
The mind Bogles
Bogle's answer was a sentence of perfect humility: "Don't look for the needle in the haystack. Just buy the haystack." And inside that humility sat the premise that made the whole machine safe, so obvious it was barely worth stating. The haystack could be trusted because other people were still searching inside it. Millions of investors, analysts and fund managers were out there pricing every stalk, buying what was cheap and selling what was expensive, and the index would simply ride behind them, a passenger on the market's wisdom, reading the prices that other people wrote.
Two things about the man are worth knowing before the machine takes over the story. The first is that he built it all between cardiac wards. Bogle had his first heart attack at thirty-one, and five more after that; a pacemaker in his 30’s; and at 66, after 128 days in a hospital bed on intravenous fluid, he was given the heart of a 26-year-old man, woke from the surgery, and asked for a pencil and a pad. Half his life was lived on doctors' borrowed time and the last two decades on a borrowed heart, which perhaps explains a man in no mood for wasted fees. The second thing is the one this newsletter has learned to look for. When he founded Vanguard in 1975, he structured it as a mutual fund: owned by its own funds, which are owned by the people whose money is in them, so that every dollar saved on fees flows back to the savers, forever by design.
His rivals became billionaires many times over. Bogle died worth about $80 million, a rounding error in his industry, because at the moment of creation he had given the machine away to the people inside it. This letter has met that shape before, in a hi-fi shop on London Bridge. It is the shape of a man who cannot be bought out of his own convictions, and it is why what follows would have broken his heart a seventh time.
Fifty years on, the passenger owns the vehicle. Index funds held $21.8 trillion by last year, more than half of all American fund assets, nearly ⅔ of the money in US equity funds, and three firms, Vanguard, BlackRock and State Street, now sit as the largest shareholder of roughly nine in ten companies in the S&P 500. The folly became the default setting of the developed world's savings, and the choosers it rode behind have thinned decade by decade, priced out by the very fee war Bogle won. He saw it coming. Two months before he died in January 2019, he used a final essay in the Wall Street Journal to warn that "public policy cannot ignore this growing dominance," its impact on markets, on governance, on the system itself. His fund was built on the belief that the market knew best. His final act was to ask what happens when the market is mostly his fund.
The answer arrived on 12th June this year, on a rocket.
SpaceX listed on the Nasdaq at $135 a share, raising some $75 billion, the largest flotation in history at roughly three times Saudi Aramco's record, and valuing the company at $1.75 trillion, instantly one of the ten most valuable enterprises on earth. The accounts beneath the number warrant a pause: revenue of $18.7 billion in 2025 and a loss of $4.9 billion. The number itself rests on something thinner still. SpaceX sold 4.3% of itself. The other 95.7% stayed locked in the hands of insiders who are barred from selling; Elon Musk was locked in for 366 days, and the whole $1.75 trillion is that keyhole price, set by the smallest sliver of tradable shares, multiplied across a mountain of stock which cannot trade at all. This newsletter has met that manoeuvre before too, in a vault in London full of diamonds: value conjured by making sure the supply never reaches the market.
For most of stock market history, a rulebook stood in the way of exactly this. Indices demanded that a company float a meaningful share of itself, typically 10%, before its price would be treated as real, because a price discovered on a sliver is a rumour wearing a suit. The float minimum was the safeguard. In the spring of 2026, ahead of the largest listing ever seen, the safeguard was dismantled by the people who had built it. Nasdaq rewrote its methodology so that any newcomer ranked in the top forty by value could enter the Nasdaq-100 after fifteen trading days, cut its float requirement, and added a flourish that deserves framing: for weighting purposes, low floats are now multiplied by up to three, so SpaceX's 4.3% is counted as 12.9%.
The index does not merely tolerate the missing shares. It is instructed to imagine them. FTSE Russell shortened its wait to five trading days and agreed to admit floats below its own 5% minimum, provided the paperwork promises improvement within a year. CRSP, whose indices sit underneath Vanguard's biggest funds, invented an alternative liquidity screen. It is worth saying plainly that Nasdaq owns both the exchange which competed for this listing and the index that admitted it early, an arrangement commentators noted with some interest, and that the rules were rewritten for a class of arrivals, with OpenAI and Anthropic expected to follow through the same widened gate this year.
Then the conscription began, and it is worth standing in the room where it happened, because the room is empty. An index fund does not decide to buy a stock; the index decides, and the fund obeys; that is the entire covenant. So picture the close of trading on 7 July, SpaceX, fifteen days old as a public company, entering the Nasdaq-100, which temporarily carries more than a hundred names to make space. Across the servers of Pennsylvania and Boston, the orders flow by themselves: slivers of Apple sold, slivers of Microsoft and Nvidia sold, companies that earn hundreds of billions, exchanged for a loss-maker priced through a keyhole, in size, at speed, with no analyst, no meeting, no memo, no doubt, no human being anywhere in the chain who could be said to have decided anything.
Bloomberg Intelligence ran the arithmetic: Russell and Nasdaq-100 trackers absorb around a quarter of SpaceX's tradeable shares; S&P inclusion would take another fifth; and once the active funds benchmarked to those indices join, total demand will pass half the float. Roughly $650 billion tracks the Nasdaq-100 through ETFs alone. The machine feeds itself: forced buying lifts the price, the lifted price raises the weight, the raised weight forces more buying. Markets have an old name for buying a thing at any price on the faith that someone else must buy it after you:
‘The greater fool. ‘
The rulebooks of 2026 have achieved their final form. The greater fool has been institutionalised; the fool is now the index itself, and the index is your pension.
The one committee which remembers why the rules existed has done this before, properly, and knows what it costs. In December 2020, the S&P 500 admitted Tesla, but only after the guarded gate had done its work: four consecutive quarters of real profit, a year of seasoning, a full float. Even then, with every safeguard intact, the entry forced the largest index trade in history, tens of billions rebalanced in a day, and years of argument about whether the machine had been made to buy the top. That is what admission looks like when the rules hold. On 4 June this year, S&P Dow Jones Indices looked at the alternative and folded its arms, announcing that "no changes will be made to the eligibility criteria": the twelve-month seasoning stays, the minimum float stays, and the profitability screen stays, which matters, because SpaceX has never reported a GAAP profit and so fails the world's most tracked index on earnings alone. The earliest it can enter is mid-2027, and only if the accounts turn.
Whatever else is said about a committee in a Manhattan office, the S&P is currently the last major index still doing the thing indices were founded on, waiting for the market to prove something before repeating it. Others objected in writing: the office of New York City's Comptroller, steward of the pensions of teachers and firefighters, sent a formal letter to FTSE Russell asking, in effect, why the safeguards protecting its members' money had been dismantled on the eve of the largest listing in history. The people whose savings were conscripted did notice. Their letter is on the record.
Be fair to the machine, because the machine is one of the great inventions. Bogle's folly beat the professionals so thoroughly and so cheaply that it returned hundreds of billions in fees to ordinary savers, democratised investing more than any device before it, and remains, for almost everyone, the most sensible home for their pension. Nothing in this letter is advice to flee it. The error is a category error, and it was Bogle's own late diagnosis: an index is a mirror, and a mirror is only wise when something is standing in front of it. Indexing worked because price-makers outnumbered price-takers, because the haystack was being searched. Five decades of success have inverted the ratio, and on 12 June the inversion completed its journey: the mirror was pointed at a keyhole and instructed to call what it saw a price.
As for the man at the centre, the facts can stand on their own. Musk retains around 42% of the equity through shares carrying 10 votes each, giving him majority control of a public company, meaning the chief executive can be removed only by a vote of the shares he himself commands. The index funds which were obliged to buy in, have no say worth counting, and neither, therefore, do the pensioners behind them.
There is a strange rhyme here with the asset the respectable world spent fifteen years sneering at. Bitcoin's defining feature was always its honesty about the void: no earnings, no anchor, no floor, a price made of belief all the way down, and every buyer told as much at the door. The casino admits it is a casino. The index was sold as the opposite house, the anchored one, prices fastened to profits and proven by seasons, which is exactly why governments let it hold the pensions. What happened in June was the smuggling of a crypto-shaped number into the anchored system, a valuation resting on belief, scarcity and a locked door, wearing the market's most respectable name. The coin buyers at least chose the distance between themselves and the thing they hold. The pension holders had the distance chosen for them, and were not sent so much as a letter.
Which is the part that belongs to you, and in Britain it belongs to you twice over. Since 2012, the law has enrolled every worker in a pension by default, and the default fund is almost always a global tracker that follows indices. So the state placed you inside the machine without asking, and this spring the machine's rulebook was rewritten around you, also without asking. In the weeks after 12 June, some of your retirement bought a slice of a rocket company that loses five billion dollars a year, at a price set by 4% of its shares while everyone who knows it best was forbidden to sell. The covenant of indexing runs one way: the rules decide, the fund obeys, and you own what the weightings say you own, which was a magnificent bargain while the rules were guarding the gate and is a different proposition now that the gate is being redrawn to fit the arrivals. The question this letter keeps returning to is: “Who owns the thing?” “What do they need from it?” and “What can they refuse?” have an unusually clean answer here. You own it. You were not consulted. You cannot refuse.
This story has an appointment in the diary. In June 2027, the lockups expire, and 95% of SpaceX becomes free to sell, at almost exactly the moment the company first becomes eligible, if profitable, for the S&P 500. The sellers are unmuzzled, and the largest buyer conscription yet arrives in the same season. Somewhere in that collision, the keyhole price meets the market for the first time, and everyone with a pension is on one side of it.
Somewhere, too, there is a person who holds none of this, no tracker, no pension pot, no coin, watching from the far bank, and the view from there is very clear: the distance between an ordinary saver and the decisions that set the value of what they hold has never been wider, and the instruments have never sounded more reassuring. Jack Bogle built a machine to follow the market on the humble bet that other people knew the prices better than he did, gave the machine to the people whose money it held, and spent his borrowed decades warning that the following had grown too large.
He died before the day his machine, rules freshly rewritten, followed 4% of a rocket company into the savings of people who have never heard its ticker. Buy the haystack, he said, because the needles were priced by those who searched for them. There are fewer searchers every year. The haystack is mostly buying itself now, and it has just been taught that it will swallow whatever the gatekeepers admit, at whatever the keyhole says, no questions asked, because asking questions was never the machine's department. It was ours.
See you on the next one.
