Some disputes do not start in court.
They start with a report, a share-price move, and a question that spreads quickly through the market: what if this is true?
That is what happened when Grizzly Research published a short-seller report on Partners Group in April 2026. The report questioned aspects of the Swiss private markets firm’s valuation practices, with a particular focus on evergreen funds and selected portfolio exposures. Grizzly also disclosed that it had taken a short position in Partners Group’s shares.
Partners Group responded quickly. It rejected the report in strong terms, called it frivolous, defamatory and highly misleading, and said it was considering legal action and possible regulatory filings for market manipulation.
That response was necessary.
But it was not enough to end the story.
