Accelerant Holdings
A data-driven marketplace that connects specialty insurance underwriters with the capital providers who back their policies, Accelerant's "Risk Exchange" platform helps smaller insurers write niche commercial coverage. Founded in 2018 by insurance veterans, the name comes from the word for a substance that speeds up a process—fitting for a platform built to accelerate how specialty risks get insured. Its founders were famously "pugnacious" about modernizing an industry stuck with outdated technology.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 6 months: -539.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
