Nuclear Verdicts by the Numbers: The Scale of the Threat Your Organization Faces

The term "nuclear verdict" entered the insurance industry's vocabulary roughly a decade ago to describe jury awards that seemed impossibly large — outliers that disrupted the actuarial models built around more predictable outcomes. That framing no longer holds. Nuclear verdicts are not outliers. They are the new baseline for high-exposure liability litigation in the United States.

In 2024, 135 corporate defendants received jury verdicts of $10 million or more — the largest number ever recorded in a single year, and a 52% increase over 2023 alone. The total value of those verdicts was $31.3 billion, more than doubling year-over-year. Since 2020, the number of nuclear verdicts has increased by 309%, their total value by 273%, and their median size by 143%.

These are not random events. They are the output of a litigation ecosystem that has been systematically engineered over the past decade by a well-funded, well-organized, and rapidly evolving plaintiffs' bar — operating in venues where anti-corporate sentiment runs deep, backed by institutional investors with billions at stake, and supported by advertising campaigns that pre-condition jurors before a single case is filed.

Understanding the scope of this threat is the starting point for everything the Social Inflation Risk Alliance does. This briefing provides the data foundation.

Nuclear verdicts have existed for decades. What changed after 2020 was the rate of acceleration. Court closures during the pandemic created a backlog that, when released, produced a wave of litigation into venues already primed with anti-corporate sentiment — and a plaintiffs' bar that had spent two years sharpening its tactics and its technology.

Swiss Re Institute's Social Inflation Index — the first rigorous attempt to separate litigation-driven claims growth from ordinary economic inflation — found that social inflation in the United States reached a 20-year high of 7% annually in 2023. Over the prior decade, social inflation drove liability claims costs 57% higher than economic factors alone can explain. That gap has not closed. It is widening.

In 2024, nuclear verdicts occurred in 34 states — up from 27 in 2023. The geographic spread of the problem is accelerating. But concentration remains in a predictable set of plaintiff-friendly states that together account for the majority of both verdict frequency and total dollar value.

For members operating hotels, real estate, habitational properties, and gaming facilities — which by their nature are anchored in specific physical locations — venue exposure is not abstract. The state where your property sits, and the county where any litigation would be filed, directly determines the statistical probability and likely magnitude of a nuclear verdict against your organization.

Nuclear verdicts are no longer concentrated in a handful of industries. In 2024, 55 different industries were the subject of at least one nuclear verdict — up from 48 in 2023. Marathon Strategies' research explicitly names hotels, restaurants and leisure, and real estate among the sectors drawing lawsuit attention.

For the Alliance's four segments — commercial real estate, habitational, hospitality, and gaming — this is not background noise. These are named targets in the data.

Swiss Re's 2025 Behavioral Social Inflation Study — drawing on a nationally representative survey of 1,150 U.S. adults presented with randomized legal simulations — quantifies what the industry has long suspected but rarely been able to prove: juror attitudes toward corporations and damage awards have undergone a measurable, structural shift.

This is not anecdote. It is documented behavioral data from a peer-reviewed methodology designed specifically to isolate the non-economic drivers of claim severity. The findings are striking.

The ATRF's annual Judicial Hellholes report — published since 2002 — provides the most comprehensive publicly available ranking of U.S. jurisdictions where corporate defendants face systematically unfair conditions. These are venues where nuclear verdicts are not outliers but norms, where judges issue liability-expanding rulings, and where litigation tourism from out-of-state plaintiffs is actively encouraged.

For members operating in multiple markets, this list is essential reading. The Alliance incorporates Judicial Hellholes data into its ongoing venue intelligence and publishes venue-specific briefings as part of the Intelligence pillar.

Sentry Insurance's 2025 C-Suite Stress Index — a survey of 1,000 business leaders across industries — found that nuclear verdicts have moved from a theoretical concern to an existential one for the majority of organizations. The findings align closely with Swiss Re's research on the structural shift in juror attitudes and Marathon's data on verdict frequency and size.

The numbers in this briefing are not projections. They are the documented record of what has already happened. And the research consensus — from Swiss Re's economists to Marathon's analysts to Norton Rose Fulbright's corporate counsel survey — is that 2025 and beyond will not be easier. Attorney advertising exceeding $2.4 billion annually continues to prime jury pools. Third-party litigation funding now backs 82% of U.S. law firms. Anti-corporate sentiment among jurors has reached a structural high.

The Social Inflation Risk Alliance was organized precisely because no comparable purchasing group or specialty program existed to address this threat from the member and insured perspective. The threat briefings in this series establish the problem. Subsequent briefings in the alliance's Intelligence, Preparedness, Defense, and Coverage series address what members, brokers, and carriers can do about it.

The threat is documented. The question is whether your organization is prepared for it.

Subsequent briefings in the Threat Series examine the specific forces driving these numbers — juror attitude shifts, plaintiff attorney tactics, third-party litigation funding, attorney advertising, and the structural weaknesses in how organizations and their carriers currently respond. This briefing establishes the foundation. The series builds from here.
