Hedge funds are increasing leverage across strategies as they position for continued upside in AI-linked equities, adding to concerns that risk-taking in global markets is becoming more concentrated and increasingly dependent on stable funding conditions, according to a report by Bloomberg.
Prime brokers and investment banks are providing a growing share of that leverage through total return swaps, repo financing and structured derivatives. Bank exposure to hedge funds has risen sharply in recent years to an estimated $4.5 trillion, reflecting deeper financing relationships and heavier use of balance sheet capacity to support trading activity.
Much of the leverage is concentrated in equity-linked strategies tied to large-cap technology and AI beneficiaries, where hedge funds have increased gross exposure through derivatives rather than outright cash positions. This has allowed managers to amplify directional bets while maintaining portfolio flexibility amid volatile factor rotations.
The trend has been reinforced by the continued rally in AI-related stocks, which has encouraged funds to add risk rather than de-gross. Industry positioning data suggest hedge fund equity beta has moved higher in 2026, with performance increasingly sensitive to the direction of a narrow group of mega-cap technology names.
At the same time, leverage is being layered across strategies including equity relative value, macro and rates trades, with the Treasury basis trade and swap spread positioning also contributing to elevated gross exposure across the sector.
Market participants warn that while balance sheets at major banks remain well capitalised, the scale and interconnectedness of hedge fund leverage means that any tightening in funding conditions or sharp equity drawdown could force rapid deleveraging. That in turn risks amplifying volatility through margin calls and forced selling, particularly in crowded AI-linked positions.
For now, leverage remains a key performance driver as hedge funds seek to enhance returns in a market increasingly dominated by momentum and concentration in a small number of large-cap growth names.
