Rolls-Royce’s share price hit a fresh all-time high this week, trading near 1,550p, and is up 1,750% in four years. The author asked ChatGPT’s free version for its 2030 share price forecast, while cautioning that AI chatbots can be sycophantic and fuel confirmation bias. Rolls-Royce is targeting between £5bn and £5.3bn in free cash flow by 2028 and running a £7bn-£9bn share buyback programme between 2026 and 2028. ChatGPT gave three scenarios: bear 1,500p, base 2,500p to 3,000p, and bull 4,500p. The author, a shareholder, finds the bull case unlikely, as it assumes £8bn in free cash flow by 2030, a multiple of 30, and aggressive share count reduction; this year’s expected free cash flow is roughly £4bn. The base case seems more doable, assuming free cash flow hits £6.25bn, putting the share price at about 2,500p, roughly 63% higher than today. The bear scenario assumes global aviation turbulence, hitting cash flows and contracting the valuation multiple, leading to a disappointing four-year return.
