IRS plans formal guidance and potential restrictions on trades used to create ordinary losses, naming currency bets and equity swap-plus-futures combinations as areas under review.

AQR’s Delphi Plus strategy, which reported large ordinary losses in 2025 and had $6.6 billion in assets midyear, is the best-known product tied to this approach.

Tax-aware long-short strategies have expanded rapidly, drawing over $150 billion in a three-year span and prompting scrutiny over whether some funds are primarily tax-motivated.

The useful part

Tax-slashing strategy popularized by largest hedge fund faces IRS crackdown | Accounting Today Author Follow Us facebook linkedin whatsapp twitter © 2026 Arizent. Stefani Reynolds/Bloomberg A strategy popularized by AQR Capital Management, the world's largest hedge fund, to help wealthy people slash their taxes on ordinary income is facing the most concrete sign yet that U.S. AQR runs the best known strategy — dubbed Delphi Plus — aimed at producing that outcome.

What to take from it

For many, it's the "holy grail," said Orso Partners portfolio manager Nathan Koppikar, a short seller who has been betting that authorities would intervene. "The total addressable market is huge if the Treasury doesn't do anything about it," said Daniel Hemel, a professor at New York University School of Law. It would be "carried interest on steroids," he said, referring to the controversial low rates that private equity executives long paid on their gains.

Example or evidence

  • In an additional publication, the agency also dealt with so-called 351 conversions, in which investors seed exchange-traded funds that later diversify their holdings without triggering tax bills.
  • Tax-aware long-short trading strategies have exploded in popularity, by some estimates attracting more than $150 billion in just three years.
  • Many involve placing long and short bets on stocks, then exiting trades that lose money to lock in some losses for tax purposes.
  • AQR helped pioneer the strategy and spread the word, turning itself into an industry giant.

Details worth keeping

Processing Content As part of an array of warnings to Wall Street on Monday, the Internal Revenue Service said it plans to publish guidance and may take other steps to bar certain trades that money managers are using to help clients harvest losses and lower tax bills on ordinary income. Representatives for AQR didn't reply to messages seeking comment. That would also take an even bigger bite out of U.S.
