Bridgewater flagship macro fund gains 8.1% in first half amid volatility, sources say

• Bridgewater's AIA Macro fund, which uses AI for investment decisions, manages about $4.5 billion and has posted 11.3% annualized returns since launching in late 2023
• The Pure Alpha 18 fund surged 17% in the first half, capitalizing on tariff-driven market uncertainty, following a 34% gain in 2025 that marked the firm's highest profits in its history
• The strong performance follows CEO Nir Bar Dea's strategic reset that included restricting new inflows into Pure Alpha and returning some assets to clients to maximize returns after years of underperformance

Bridgewater Flagship Macro Fund Gains 8.1% in First Half Amid Volatility

Key Performance Highlights:

Bridgewater Associates' flagship Pure Alpha macro fund returned 8.1% in the first half of the year, navigating volatile markets driven by geopolitical tensions including the Iran war. The firm's AI-powered AIA Macro fund matched this performance with an identical 8.1% gain during the same period.

Firm Overview:

Bridgewater currently manages approximately $102 billion in assets under management. The AIA Macro fund, launched in late 2023 under co-CIO Greg Jensen, has generated an 11.3% annualized return and now oversees $4.5 billion. The firm's Pure Alpha 18 fund significantly outperformed with a 17% first-half gain, capitalizing on tariff-driven market uncertainty.

Market Context:

The hedge fund industry rebounded strongly after initial losses from the Iran conflict. The S&P 500 and Nasdaq Composite rose 9.67% and 12.48% respectively during the first half, approaching record highs. Competing multi-strategy funds like Millennium and Point72 posted double-digit gains. Goldman Sachs noted all nine tracked hedge fund cohorts delivered positive year-to-date returns, with particular strength in fundamental long/short and macro strategies.

Strategic Developments:

The results reflect benefits from CEO Nir Bar Dea's 2023 strategic overhaul following his takeover of the firm founded by Ray Dalio in 1975. Bar Dea restricted new inflows into Pure Alpha and returned some client assets to optimize returns, reversing years of underperformance. Bob Prince was recently appointed board chair. The firm continues expanding into AI-driven strategies and partnered with State Street Global Advisors to launch an ETF, demonstrating its evolution beyond traditional macro investing.
