OpenAI helped ignite the biggest technology investment cycle in decades, but cracks may be starting to appear. With monetisation under pressure and ads entering ChatGPT, investors are beginning to question whether the company at the centre of the AI boom can sustain the trillion-dollar ecosystem built around it. Tom Dalrymple, Investment Analyst at Aubrey Capital Management, has shared his thoughts.
Itโs no secret that OpenAI has bills to pay. Several high-profile deals with Oracle ($300bn), Microsoft ($250bn) and Broadcom ($350bn), among others, amount to over $1tn of commitments across varying time horizons. While the growth of ChatGPT has been exponential, its ability to fund this has come into question in the investment community, and now seemingly within OpenAI itself. Having declared a โCode Redโ following the release of Googleโs Gemini 3 model last year, ChatGPT has started running ads in a move that Sam Altman himself previously labelled a last resort. The question is whether this attempt at monetisation is coming from a position of strength or weakness.
A key part of this shift has been the realisation that monetising consumers through a subscription model is proving harder than expected. While uptake has been rapid for ChatGPT, data suggests that it is still struggling to become a day-to-day part of peopleโs lives. The latest daily and weekly active user figures suggest engagement, based on daily and weekly active users (DAU/WAU), remains relatively low at 22%. For reference, apps such as Instagram are typically north of 50%.

This is also reflected in the relatively low levels of paid conversion to the premium tiers, with 3.7% of WAUs converting to premium subscriptions (Jan 2026) versus ~5% at the end of 2024. While 3.7% is not bad in isolation, it does not appear sufficient to justify the levels of investment. Improvements to the model and new features should be driving greater conversion of the user base rather than less. This challenge was acknowledged publicly on X by Sam Altman himself: โIt is clear to us that a lot of people want to use a lot of AI and donโt want to pay.โ
The consequences of these troubles are well documented. Oracleโs bond yield has increased significantly, and its share price has halved, as its debt raising to fund data centre infrastructure for OpenAI has begun to ring alarm bells. It is worth noting that its promise to raise โonlyโ $50bn this year has also failed to halt its slide. Microsoft has also taken a beating, with 45% of its backlog attributed to OpenAI, in a similar vein to Oracle.

Doubts over its ability to meet these commitments are clearly starting to weigh on investor sentiment, and OpenAIโs $1tn+ of commitments now look like a bigger number than they did even six months ago, particularly with a still uncertain ROI.
However, what looks underappreciated is the broader impact across the โpicks and shovelsโ space, which has been a huge source of performance over the past two to three years. While Microsoft and Oracle have borne the brunt, both companies are supplied by a huge ecosystem of AI-adjacent companies. For example, Nvidia is a leading supplier to Microsoft, Oracle and Amazon, which together hold over $600bn of cloud infrastructure commitments, putting a spotlight on their future pipeline should OpenAI begin to fall behind. Microsoft alone accounts for ~19% of Nvidiaโs revenue.
In effect, OpenAI has become the marginal buyer of high-end AI compute. Any slowdown in its ability to fund or monetise that demand would therefore transmit rapidly through hyperscalers and into the semiconductor supply chain.
Further up the supply chain on the hardware side, familiar names such as SK Hynix, Micron, TSMC, KLA and ASML are all key suppliers to a further ~$550bn of commitments to Nvidia, Broadcom and AMD. Many of these names continue to perform very well, reflecting extraordinarily little of the risk that appears inherently priced into Microsoft and Oracle. OpenAIโs upcoming IPO in either late 2026 or early 2027 should help to alleviate some of the funding concerns. It will also provide an interesting barometer for the sustainability of the AI trade.
Talk of an AI bubble seemingly disappeared at the beginning of 2026, supported by further commitments from Meta and Microsoft to increase capex forecasts beyond all expectations. We do not view this commitment as likely to change but are concerned about the prospect of OpenAI overextending itself and the impact this could have. We have reduced or avoided the names most exposed to OpenAIโs supply chain and will continue to do so until we see sufficient upside to their performance. Given OpenAIโs importance to the overall AI narrative, failure to sufficiently monetise
its new advertising venture begins to look like a key catalyst that could turn talk of a bubble into reality. We remain selective and underweight U.S. technology companies, and continue to urge investors to remain cautious about extending their exposure to the broader AI supply chain.
