India, Saudi Arabia and a cluster of emerging economies are set to see the fastest growth in billionaire populations by 2031, according to global wealth research by Knight Frank. The world’s billionaire count, now at about 3,110, is projected to approach 3,915 by 2031, an increase of roughly 25% over five years. Among major nations, India stands out with a forecast 51% jump in billionaires, from 207 in 2026 to 313 by 2031.
India’s share of global billionaires is expected to rise from 6.7% today to about 8% by 2031, moving it firmly into the top tier of wealth‑creating nations. This growth is being driven by a booming technology sector, rising start‑up IPOs and private‑equity exits, as well as strong performance in listed equities and family‑owned businesses. India’s ultra‑high‑net‑worth individual (UHNW) base is also projected to grow by 27% to around 25,217 by the same year.
Oil‑rich Saudi Arabia is tipped to see the most dramatic relative increase, with its billionaire count expected to more than double from 23 in 2026 to 65 by 2031. Other fast‑moving markets include Poland, whose billionaires may rise from 13 to 29, and Sweden, where the count could climb 81% from 32 to 58. These shifts reflect a broader trend of wealth creation spreading beyond the traditional hubs of the US and China, where growth is still positive but slower.
The report suggests that the fastest expansion in billionaire ranks will come from economies with strong capital markets, rising digitalisation and favourable policy environments such as India and Saudi Arabia. This acceleration is likely to widen wealth gaps even as it fuels higher investment, M&A, and demand for luxury assets and prime real estate in these countries.
