The rolling bubble: stop asking whether AI is one, ask which layer is repricing
Dhaval Joshi says software, silver and semiconductors each boomed and broke in turn as investors kept misjudging who captures AI's value. The rotation is what has kept the selloff from correlating.

Why it matters
On August 3, Dhaval Joshi posted on LinkedIn that AI is not one bubble waiting to pop but "a rolling SEQUENCE OF BUBBLES," in which capital leaving one deflating sector inflates the next one in line [17]. Joshi, until recently chief strategist for the Counterpoint strategy at BCA Research in London [1], argues the useful question is not whether AI is a bubble but which AI bubble is popping today [18].
That reframing is more useful than the bubble-or-not argument because it implies a rotation rather than a single date. Joshi's account is that investors keep misjudging, then correcting, who or what actually captures AI's value [19]. By his own chart, three layers have already been through the cycle [14]. Software rallied on the idea that AI would be a productivity tool, then crashed once investors decided AI agents threatened the SaaS subscription model itself: "So, the software boom turned to bust" [3]. Silver spiked on its status as the best electrical conductor for power-hungry data centres, which Joshi says "could not justify a near trebling of the silver price when there are other good conductors" [6] - roughly a 200 per cent advance to unwind [16]. Semiconductors rose on the premise of near-limitless pricing power; Joshi says chipmakers have no moats around their profits, and "astronomical margins will crash back to earth when demand and supply equilibrate, as they ultimately must. So, the semis boom is unwinding - though has further to go" [24].
The software episode is the one with a direct read-through for anyone selling seats: the derating was not a verdict on AI working badly, it was a verdict on the pricing model [3]. Joshi frames the wider problem as a margin question rather than an earnings question. He told Fortune he slightly disagreed with BCA's Peter Berezin that this is an earnings bubble, calling it a "profit margin bubble" instead, with the market now asking "How is the E high?" and whether those margins can be held [22].
The obvious objection is that this is just price discovery, and Fortune puts it directly: markets test a thesis, find it wrong, correct [21]. Joshi's answer is amplitude. "If you can make a fortune in a matter of weeks or months, and, crucially, then lose it all just as quickly or even quicker, then that constitutes a 'bubble'" [20]. He describes something closer to narrative contagion that briefly grips a sector and then rolls elsewhere, and notes the silver leg shows the misallocation is not confined to equities [7].
The consolation, for now, is mechanical: because each deflation coincides with a reinflation somewhere else, there has been no correlated selloff [5]. That is also the fragility. Joshi has argued since July 2023 that AI hype would not automatically become profits for the leading tech companies, drawing parallels to the 1990s [11], and the 1990s precedent is unkind to funders: the buildout created enormous value, but the fibre that bankrupted its original owners still carries the internet for entirely different shareholders [13].
Watch the liquidity that powers the rotation. A rolling sequence needs a steady stream of optimism and capital, and a deteriorating economy could slow or reverse the flow between sub-sectors [23]. Watch hyperscaler free cash flow, which the latest earnings season showed being consumed by capital expenditure, with Google going free cash flow negative for the first time in its history [10]. And note that the consensus is already crowded: Jamie Dimon has repeatedly flagged elevated valuations, Bank of America's Global Fund Manager survey has named an AI equity bubble the top tail risk, and Sam Altman, David Solomon and Jeff Bezos have all conceded something bubbly is happening [8] - while the pop that was due in 2025 has not arrived [9].

Joshi produced a chart showing software stocks rallied on the idea that AI would be a productivity tool, then crashed as investors realised AI agents were threatening the SaaS subscription model itself: "So, the software boom turned to bust."
- [4]
Joshi said the rolling framing would explain the "SaaSpocalypse" in the software-as-a-service sector as well as volatility in silver and semiconductor stocks.
- [5]
Joshi said the cyclical nature of the reinflation has, for now, prevented a correlated selloff, and asked what investment, if any, comes next in the rolling sequence.
- [6]
Silver prices spiked because the metal is seen as the best electrical conductor for power-hungry data centres; Joshi said that on reassessment this "could not justify a near trebling of the silver price when there are other good conductors."
- [7]
Joshi frames the episodes as narrative contagion setting in briefly, like a mania, before rolling off somewhere else, and says the silver example shows the misallocation is not confined to equity markets.
- [8]
Jamie Dimon has repeatedly voiced concerns over elevated valuations; Bank of America Research's Global Fund Manager survey has named "AI equity bubble" as the top tail risk; and OpenAI CEO Sam Altman, Goldman Sachs CEO David Solomon and Amazon founder Jeff Bezos have conceded that something bubbly is going on.
- [9]
The bubble was supposed to pop in 2025 and yet has kept going.
- [10]
The latest earnings season changed the conversation on hyperscaler free cash flow, which is being eaten by capital expenditure, with Google going free cash flow negative for the first time in its history.
- [11]
In July 2023, Joshi cautioned that AI hype would not automatically translate into massive profits for the leading tech companies, drawing explicit parallels to the 1990s technology bubble.
- [12]
From June through August 2026, Joshi maintained a consistently skeptical posture on AI-driven equity gains, questioning whether the capital expenditure pouring into AI infrastructure will generate adequate returns over a reasonable time horizon.
- [13]
The 1990s internet buildout created enormous long-term economic value, but the companies that funded the infrastructure largely did not capture it: the fibre optic cables that bankrupted their original owners still carry the internet today, for the benefit of entirely different shareholders.
- [14]
Joshi names three distinct layers that have already boomed and broken in sequence: software, silver and semiconductors.
- [15]
Joshi's tenure as BCA Research chief strategist ran about five years and four months.
- [16]
A near trebling of the silver price implies an advance of roughly 200 per cent from the starting level.

Dhaval Joshi posted on LinkedIn on August 3 that AI is not a single bubble waiting to pop but "a rolling SEQUENCE OF BUBBLES", in which capital fleeing one deflating sector inflates the next one in line.

Joshi argues the right question is not whether AI is a bubble but which AI bubble is popping today.

Joshi describes a rapid-fire sequence of bubbles popping and inflating in a rolling pattern, with investors misjudging and then correcting who or what will actually capture AI's value.
- [20]
Joshi's definition of a bubble: "If you can make a fortune in a matter of weeks or months, and, crucially, then lose it all just as quickly or even quicker, then that constitutes a 'bubble.'" He said normal reassessment of winners and losers should not be so extreme in magnitude and rapidity.
- [21]
Fortune notes the obvious counter is that this is simply price discovery - markets testing a thesis, finding it wrong and correcting - with amplitude the difference, as a near tripling of silver overshoots any plausible fundamental by an order of magnitude.
- [22]
In an interview with Fortune, Joshi said he slightly disagreed with his former BCA colleague Peter Berezin that the market is in an earnings bubble, calling it more of a "profit margin bubble": the market is finally asking "How is the E high?" because margins are very high and may not be maintainable.
- [23]
If economic conditions deteriorate, the capital flowing between AI sub-sectors could slow or reverse entirely; a rolling sequence of bubbles requires a steady stream of optimism and liquidity to keep the rotation going.
- [24]
Semiconductors rose on the idea of seemingly limitless pricing power for chipmakers; Joshi argued investors are realising chipmakers lack moats around their profits, and predicted: "Astronomical margins will crash back to earth when demand and supply equilibrate, as they ultimately must. So, the semis boom is unwinding - though has further to go."
