In 2019, the company abandoned its electric car project, citing a lack of commercial viability.

The company is a major player in the UK’s shale industry, with its 600-foot “Dragon Ships” pioneering the transport of US shale gas to Europe.

Ratcliffe mortgaged his home in 1992 to finance the buyout of a BP chemicals unit, and six years later, he used assets from that deal to establish Ineos.

In 2021, Ineos acquired two chemical divisions from BP for $5 billion, and in 2022, it launched petrochemical joint ventures with Sinopec worth over $7 billion.

In 2023, Ineos expanded further by purchasing $1.4 billion in US onshore oil and gas assets from Chesapeake Energy.

After a challenging foray into equities and a period of underperformance that triggered investor withdrawals, Platt returned all outside capital in 2015 and transformed BlueCrest into a private family office.

Since then, the firm has thrived - delivering standout returns, including 153% in 2022 and 95% in 2020, with no annual performance dipping below 20%.
