Insurance Broker M&A Activity Slows Sharply in 2026 as Private Equity Tightens Its Grip
Merger and acquisition activity among insurance agents and brokers has slowed to its weakest pace in years, with 439 transactions recorded in the first three quarters of 2026, down 19% from 539 in the same period of 2025, according to Optis Partners’ quarterly report.
The third quarter alone produced 144 deals, a 27% decline from the 197 announced in the third quarter of 2025. On a trailing 12-month basis, 600 deals closed through September 2026, down 21% from 763 in the 12 months ended September 2025, a pace Optis Partners said was the lowest since the 578 deals logged in the 12 months ending in the second quarter of 2018.
Private Equity Dominance Grows Even as Deal Counts Fall
Private equity-backed and hybrid buyers accounted for more than 76% of all announced transactions over the past 12 months and in the most recent quarter, OPTIS Partners found. Privately owned buyers, by contrast, recorded 96 deals in the trailing 12-month period, down 28% from 134 in the comparable period a year earlier, and their share of total deals slipped to 16% from 18%.
Over the past five years, private equity firms have closed between 68% and 76% of all deals in any trailing four-quarter period, while privately owned firms have recorded 15% to 23% and publicly traded brokers 5% to 8%, according to the report.
Despite the overall slowdown, industry consolidation has narrowed among buyers themselves. Optis Partners identified 82 unique buyers over the trailing four quarters, and for the first time, private equity-backed buyers (43) outnumbered all other buyer types combined (39), including privately owned firms, public companies and banks.
The top 10% of buyers now account for 55% of completed deals, up from 46% in 2021. Turnover within the private equity-backed group was notable: 20 of the 43 current buyers have sold or otherwise ceased acquisitions, replaced by 23 new entrants, while the number of all other buyers fell to 39 from 101 over the same span.
Broadstreet and Inszone Lead a Shrinking Field of Active Buyers
Broadstreet Partners led all buyers with 57 transactions in the first three quarters of 2026, matching its total for the same period in 2025 and running 25% above its previous five-year average, according to Optis Partners. Inszone Insurance Services followed with 48 deals, up 41% from the prior year period and 79% above its five-year average. Hub International recorded 22 transactions, down 42% from the previous year and 50% below its five-year average.
On a trailing four-quarter basis, Broadstreet Partners reported 69 deals, 16% above its five-year average, while Inszone Insurance Services posted 59 deals, 53% above its average. Hub International trailed with 33 deals, 46% below its average.
Among buyers completing at least 20 deals in the trailing 12-month period, only eight firms reached that threshold, the fewest since 2020, Optis Partners said. Just two increased their deal flow: OneDigital, up 50%, and Inszone, up 31%. Keystone Agency Partners and Hub International slowed the most, each down roughly a third, according to the report.
Large Recapitalizations Reshape the Top of the Market
While overall deal counts have declined, several of the industry’s largest brokers pursued sizable transactions in 2026.
Willis Towers Watson agreed to acquire Newfront, estimated at $250 million in revenue, in January. Aon announced a deal for USI, estimated at $3 billion in revenue, in August, expected to close in the fourth quarter. DFO Management and Sequence Holdings agreed to acquire The Baldwin Group, estimated at $1.7 billion in revenue, in September, with closing expected in the first quarter of 2027.
Optis Partners noted that Gallagher, Brown & Brown and Aon have made fewer acquisitions overall but have targeted large private equity-backed firms to strengthen their middle-market positions, and said it expects more recapitalizations and large transactions as platforms acquired between 2019 and 2021 reach or pass typical hold periods.
