Aon has introduced Sidecar X to offer up to $200m (£147.74m) of capacity for transactional risk insurance.
The facility sits within Aon’s Global Sidecar Platform, which covers representations and warranties insurance alongside tax insurance.

Sidecar X is being rolled out across the US, Canada, the UK, the European Economic Area and Asia, spanning the same two product lines.
In a statement, the company said: “The Global Sidecar Platform spans representation and warranties and tax insurance products and provides a streamlined experience through pre-agreed underwriting and claims frameworks, delivering a 10% premium discount.”
Access to Sidecar X is limited to Aon’s own client base.
The insurer said underwriting and claims are handled through “pre-negotiated, delegated frameworks” designed to reduce processing time.
The platform draws on insurer capital together with Aon’s analytics capabilities and market reach and is aimed at clients working on mergers and acquisitions and tax-related transactions on a global basis.
Aon said participating insurers and reinsurers gain from what it described as a “disciplined, analytics-led approach to diversified transactional risk, enabling more informed underwriting decisions and scalable, sustained capital deployment”.
The company linked the launch to efforts to strengthen ties between insurers, reinsurers and clients in the transaction solutions market amid larger, more complex deals and rising demand for risk transfer capacity, even as capital grows more selective.
Aon commercial risk CEO Christian Hoffmann said: “As transaction risks become increasingly complex, our clients need greater clarity and solutions that help them navigate an evolving market.
“Sidecar X demonstrates our commitment to delivering differentiated risk solutions that help clients achieve better outcomes.”
The announcement follows Aon’s move last month to raise capacity in its Data Center Lifecycle Insurance Programme to $5bn, broadening cover for digital infrastructure assets across development and long-term operational phases.
Aon attributed the expansion to growing investment in AI, cloud computing and hyperscale data centres, which it said is fuelling demand for insurance across larger, more complex and more capital-intensive projects throughout their life cycle.
