Antitrust Read: Event-Driven / Merger Arb

The spread on a pending merger was wide because the market doubted it would clear. The desk's entire return depended on one probability: would antitrust regulators block or clear the deal? The team wanted independent expertise, former agency staff and antitrust economists, to pressure-test their own read before sizing the position.

The Challenge

What was at stake

Deal-closure odds drove the whole trade, and public commentary was noisy and conflicted. The desk needed a structured, independent read on the regulatory path, block risk, remedies and timeline, from people who understood how the relevant agencies actually decide. Getting the probability wrong meant mispricing the spread.

In Their Words

Anonymised, role-based

The market priced fear. We wanted a probability. Six people who understand how these agencies actually decide gave us a range we could size against.

Anonymity & Compliance

How this study was produced

This is a representative, anonymised composite of a typical hedge funds engagement. Client identity is removed and the figures illustrate the format and scale of the work. They are not a record of a single named mandate. Every expert call is scoped to general market knowledge, screened for material non-public information before findings reach a deal team, and documented for audit. See our compliance framework for full detail.
