Jun 1, 2026 · Milliman Quarterly PMI Market Update, 1Q 2026
Primary NIW printed $78.8 billion in the first quarter
Purchase was 77% of the flow. Six writers, and none of them ran away with the quarter.
Milliman put first-quarter new insurance written at $78.8 billion: $60.9 billion purchase and $17.9 billion refinance. Arch wrote $14.8 billion (18.8% share), then MGIC $14.4 billion, Radian $13.5 billion, Enact $12.8 billion, NMI $12.3 billion, and Essent $11.1 billion.
Arch’s $14.8 billion includes a $2.2 billion non-GSE bulk transaction, about 15% of that company’s quarter. The other five prints are flow. Bulk and flow should not share a row in a credit cube.
The six-carrier set is unchanged: Arch, Enact, Essent, MGIC, National MI, and Radian. That is the whole primary market.
Rank the six on the same definition. Bulk and flow do not share an LTV, a score, or a premium plan.
