Interest rates are the big wildcard. If this is the start of a significant rising cycle, akin to 2022/2023, then the AI bubble is toast and all these companies are dead. If the Fed pauses in December/January there may be a window of opportunity in early 2027 and we'll see both OpenAI and Anthropic IPO and possibly jump.
Rising interest rates are a triple whammy to AI companies: 1) risk capital always flees first when rates go up, so the available capital dries up 2) they and their suppliers have borrowed significantly to fund datacenter expansion, so rising rates will directly increase their expenses and 3) AI is considered an investment for their customers, and corporate finance always pulls back on more speculative investments when rates go up, and so their customers will likely pull back and directly shrink their revenue.
