A sky-high market debut valued somewhere between $1.5 trillion and $2 trillion is raising serious questions about Anthropic’s near-term upside for investors.
Anthropic, the AI company preparing to list on public markets this month, delivered revenue growth of 1,300% year on year in the first half of 2026, reaching $16.3 billion.
That figure dwarfs the performance of Rolls-Royce (LSE: RR.), whose revenues expanded 25% to £11.3 billion over the same period, yet the British engineering giant may still offer more compelling returns over the next 12 months.
The core problem with Anthropic’s IPO is that a valuation in the $1.5 trillion to $2 trillion range prices in near-perfection, leaving no cushion for any operational stumble or slowdown in growth momentum.
History offers a cautionary note: hyped technology listings have repeatedly collapsed after their opening-day surges, with SpaceX and Cerebras both following that pattern in 2026 alone.
Snowflake, Airbnb, and Rivian are among earlier examples of stocks that surged on IPO excitement before retreating sharply as market enthusiasm faded.
Rolls-Royce is not without its own valuation concerns, trading on a forward price-to-earnings multiple of approximately 30, which leaves limited room for disappointment in its civil aerospace or data centre divisions.
A warning from management about slowing demand, whether tied to elevated oil prices or reduced appetite for data centre power infrastructure, could send the stock lower in short order.
Even so, the average analyst price target for Rolls-Royce sits roughly 40% above where the shares currently trade, a level of consensus optimism that would be difficult for Anthropic to replicate given its enormous starting market capitalisation.
Rolls-Royce earnings are forecast to grow approximately 16% in 2027, underpinned by continued momentum across defence, nuclear energy, and data centre power, providing a relatively clear path for the share price to follow.
Weighing the growth differential against the structural risks attached to each stock, the conclusion is counterintuitive: the slower-growing company carries meaningfully less downside risk over a 12-month horizon.
Both companies retain substantial long-term potential, but investors focused on the next year face a stark choice between Anthropic’s extraordinary growth rate and the elevated valuation danger that accompanies it.
