Michael Platt’s decision to return client capital and trade exclusively with internal money has paid off in style, with his hedge fund-turned-private trading firm BlueCrest Capital Management posting an estimated 7,858% cumulative gain over the past decade.
BlueCrest gained 73% in 2025, according to a person familiar with the matter, extending a run of outsized returns since the firm stopped managing external capital in 2016. The gains were fuelled in part by heightened volatility early last year, when US President Donald Trump’s tariff announcements triggered sharp market dislocations.
The ten-year performance figure is based on compounded annual returns reported by Bloomberg and assumes no capital withdrawals over the period. Unlike traditional hedge funds, BlueCrest calculates performance on invested capital rather than total assets, with returns reported net of fees and expenses.
Platt’s move to a client-free model has allowed the firm to deploy high levels of leverage, maintain concentrated positions through periods of volatility and operate without the liquidity, disclosure and redemption constraints faced by conventional hedge funds. Court documents from 2022 suggested BlueCrest was running around $3.9bn in capital, leveraged to provide roughly $15bn in trading capacity.
BlueCrest’s trading approach is understood to focus heavily on interest rates and emerging markets, with efforts in recent years to expand its commodities business. The firm operates a pod-style structure similar to large multi-manager platforms, allocating capital to multiple trading teams while maintaining strict centralised risk controls.
The results have propelled Platt into the ranks of the world’s wealthiest hedge fund managers, with his fortune estimated at $12.8bn prior to the latest returns, according to the Bloomberg Billionaires Index. BlueCrest also delivered a standout 153% return in 2022, underscoring the volatility — and upside — of its leveraged approach.
Founded in 2000 by Platt and William Reeves, BlueCrest grew into one of Europe’s largest hedge funds, managing more than $37bn at its peak and generating over $22bn in profits for investors during its years running external capital. However, a period of subdued performance and investor withdrawals prompted the firm’s pivot away from client money in late 2015.
Today, BlueCrest operates from London, New York and Singapore and has recently secured full regulatory authorisation in Dubai.
