Comets and the Unpredictable Unknown

While asteroids travel in relatively stable orbits, comets present wilder cards. The interstellar visitor 3I/ATLAS has already upended assumptions about what kinds of objects can wander into our neighborhood from outside the solar system. Other comets, such as C/2023 A3 (Tsuchinshan-ATLAS) and 12P/Pons-Brooks, are being tracked for their brightness and trajectories. None are expected to collide with Earth, but their unpredictable behavior near the sun underscores how little control humanity has over these bodies.

The insurance industry should be considering not only the prospect of an actual impact but also the indirect risks: disruptions to satellites from dust and debris tails, geomagnetic disturbances, or mass panic from a brightening comet misinterpreted as a collision course. Each scenario creates potential claims, whether from lost communication networks, business interruption, or even liability suits over inadequate preparation.

Shareholder Duty and Policyholder Rights

The greatest concern is not simply whether insurers have run the numbers but whether they are willing to admit it. Shareholders expect risk management that is both comprehensive and transparent. Policyholders expect coverage that matches the risks they face. The silence of the industry creates suspicion that insurers have chosen to gamble with cosmic uncertainty rather than face the costs of updating actuarial models.

The obligation to disclose risks extends beyond ethics. Publicly traded insurers are bound by securities laws to provide accurate assessments of potential threats to their business. If a significant space-event risk is ignored or minimized, and losses later devastate the balance sheet, shareholders could demand accountability in court. The consequences could resemble securities litigation seen in climate-related disclosure cases, only with cosmic stakes.

A Systemic Risk Without a Playbook

Space-related catastrophes present an almost existential risk to the global insurance ecosystem. A single impact on a populated region could generate insured losses rivaling or exceeding the costliest disasters in history. Reinsurers, who pool global risk, could be overwhelmed, leaving primary insurers insolvent. The ripple effects could paralyze credit markets, real estate, and entire industries dependent on insurance coverage to operate.

The unsettling truth is that no public playbook exists for how claims would be processed in such a scenario. Would governments step in with emergency backstops? Would insurers invoke exclusions en masse? Would international bodies such as the United Nations or World Bank intervene? The lack of clarity feeds the perception that insurers are avoiding the issue altogether.
