There is a comforting illusion that takes hold whenever a great company finally comes to market and the orders come flooding in. When a business is wanted badly enough, we quietly assume the money to buy it will always be there. Demand feels infinite. Capital starts to feel like water, endlessly available, ready to flow wherever the best ideas happen to be. It is one of the most natural assumptions in investing, and it is also one of the most dangerous.
Because money is not infinite. Conviction might be, enthusiasm certainly is, but the actual pool of investable capital at any given moment is a real number. It has a size. And when too many wonderful companies reach into that same pool at the same time, something has to give. Usually it is the price.
That is the quiet risk sitting underneath the current market, and it is not the risk most people are worried about. The debate everyone is having is whether artificial intelligence is a bubble, whether the winners are overvalued, whether the story holds. Those are fair questions. But there is a second, less glamorous question hiding behind them, and it may matter more over the next year: what happens when almost everyone who matters needs to raise money, or wants to sell stock, all at once?
Why this matters now
Consider what just happened. In June, SpaceX listed on the Nasdaq in the largest initial public offering on record, raising roughly USD 75 billion at a price of USD 135 a share and a valuation near USD 1.77 trillion. The stock jumped almost twenty per cent on its first day and the company briefly carried a market value above USD 2 trillion. Demand was extraordinary. Retail investors alone put in orders worth more than USD 100 billion, and the deal was reportedly oversubscribed several times over.
On the surface, that looks like a triumph of demand. Read it again and it is also a preview of supply. One company just pulled USD 75 billion of cash out of the market in a single week. And SpaceX is not the last of them. Anthropic and OpenAI, each valued privately at close to USD 1 trillion, have reportedly filed confidentially to go public, and those deals could land this year. Earlier in 2026, the chipmaker Cerebras came to market and its shares popped sharply on debut. The queue is forming, and it is a long one.
Now add the parts most investors do not see on the ticker. Every one of those blockbuster listings comes with a lock-up period. When those lock-ups expire, employees who are wealthy on paper will want to be wealthy in the bank, and they will sell. Some large university endowments are reported to hold ten to fifteen per cent of their entire portfolio in a single private name. When that name lists, they will trim. None of these people are panicking. They are simply doing the sensible thing, turning a paper fortune into real money. But the collective effect is an enormous wave of stock that has to find a buyer.
The core thesis
Here is the argument in one line: the next stress in markets may not be a story problem, it may be a supply problem.
The point is one that Seth Klarman of the Baupost Group made recently, and it is worth restating in plain terms. The cost of capital is set by the supply of money and the demand for it. We accept this instinctively in the bond market. When governments and companies all try to borrow at once, yields rise, because there is only so much lending capacity to go around. The same logic applies to equities, we just forget it, because in a bull market it feels like the buyers will always turn up.
But look at who needs money right now. The AI labs need capital, tens of billions of it, to keep training ever larger models. The hyperscalers, the Googles and Metas of the world, are spending record sums on data centres. The utilities need capital to build the power generation and grid capacity those data centres consume, because compute without electricity is just very expensive furniture. The chip companies need capital to build new fabrication plants, some of them in the United States. And now the newly listed giants need investors to absorb waves of stock as lock-ups roll off.
Everyone is reaching into the same pool at the same time. That is not a comment on whether any one of these businesses is good. Many of them are superb. It is a comment on arithmetic. When supply of securities is this heavy and the need to raise or monetise is this urgent, prices can soften for reasons that have nothing to do with fundamentals. The tide can go out even while the companies themselves are doing fine.
Where this gets interesting for investors
If that were the whole story, it would just be a warning. But there is a second-order effect that is far more useful, and it is where the opportunity may sit.
When capital becomes scarce and attention becomes narrow, markets get lazy about sorting. The instinct becomes brutally simple: own the AI winners, dump anything that smells like an AI loser, and do not think too hard about the difference. In that kind of environment, perfectly good businesses get thrown out with the bathwater. A high quality, cash generative, sensibly priced company can be sold off simply because it has been filed under the wrong heading, or because an investor needs to free up cash to chase the exciting new listing.
That is the pattern long term investors should be watching. Not the stocks everyone is fighting to buy, but the quality names quietly being discarded to fund the buying. The market is effectively running a fire sale in one aisle to pay for a bidding war in another. History suggests the fire sale aisle is usually where the better long term value ends up being.
None of this requires a heroic macro call. It does not require predicting the top, or timing the moment the supply wave crests. It simply requires remembering that when money is being drained from the system to feed a small number of hungry giants, the discipline of buying quality at a fair price becomes more valuable, not less.
The risks and the honest counterpoint
Now for the other side, because a thesis without a counterpoint is just a sales pitch.
The most important risk here is that this dynamic is easy to describe and very hard to time. Capital has been abundant for the better part of two decades. Markets have absorbed enormous waves of new supply before and simply kept climbing. Global savings are vast, foreign money keeps arriving, companies keep buying back their own shares, and the pool of capital has repeatedly proven deeper than the pessimists expected. You can be completely correct about the mechanism and still be early by two years, which in practice can feel a lot like being wrong.
There is also the possibility that the supply gets met by genuine new demand. If the AI build-out really does lift productivity and earnings the way the optimists hope, then the appetite for equities could expand to match the flood of paper. Scarcity of capital is a risk, not a certainty.
And it is worth being honest about the flip side of caution. Klarman himself has admitted that he held too much cash for too long during the era of suppressed interest rates, and that the optionality he was preserving simply did not pay off for long stretches. Waiting has a cost. Sitting in cash to dodge a supply wave that never fully arrives is its own kind of mistake. The lesson is not to hoard and hide. It is to stay disciplined about what you pay and what you own.
There is a live macro backdrop too. Kevin Warsh took over as chair of the US Federal Reserve in May, with inflation still running above target and the market at one point even pricing the chance of a rate rise rather than a cut. A higher for longer rate environment is precisely the condition under which the supply and demand for money starts to bite. That does not make a squeeze inevitable. It does make the arithmetic worth respecting.
What sensible long term investors should actually do
For long term investors, the practical response to all of this is not dramatic, which is rather the point.
The first thing is to stay bottom up. The overall market weather matters, and it pays to keep half an eye on it, but portfolios are built one holding at a time. Knowing what you own, why you own it, and what it is genuinely worth is what keeps you anchored when the headlines get loud.
The second is to think in terms of absolute return rather than keeping up with the index. When a market becomes this concentrated in a handful of enormous names, the index stops being a neutral benchmark and starts being a bet on those specific companies. Chasing it means chasing them. A sensible investor is trying to compound wealth ahead of inflation over years, not trying to match a scoreboard that a few mega caps happen to be dominating this quarter.
The third is to treat cash and quality as tools, not comfort blankets. A little cash creates the ability to act when others are forced to sell. Quality businesses with strong balance sheets are the ones most likely to survive a squeeze and take advantage of it. The opportunity, if the supply wave does soften prices, will go to the investors who kept some capacity and kept their nerve.
This is not a call to make big directional bets on the market. It is a reminder that when everyone is admiring the demand, the smart money is quietly counting the supply.
TAMIM Takeaway
The market is transfixed by a single question: who are the AI winners? Underneath that question sits a quieter and possibly more important one: where will all the money come from? A record breaking wave of listings, lock-up expiries, endowment selling and staff monetisation is arriving at the same moment that AI labs, hyperscalers, utilities and chipmakers all need enormous amounts of fresh capital. When that many winners reach into the same pool at once, the price of capital can rise and share prices can soften, even for genuinely good companies.
For long term investors, the useful mindset is not fear, it is patience with a purpose. Do not try to time the wave. Stay bottom up, focus on quality, balance sheets and valuation, keep some capacity to act, and watch the aisle where solid businesses are being discarded to fund the excitement elsewhere. That is usually where the market’s short-termism creates the long-term opportunity.
