FDA vaccine target LP.8.1, dominant since March, plateaued in April. June sees Nimbus NB.1.8.1, scion of "razor-blade throat" XDV, push LP.8.1 out of majority.
#CDC adds NB.1.8.1 only in latest, late-published public dataset. "Software error" that heralded data delay remains unresolved. Hatching for "less reliable" data reflects "low numbers of sequences being reported".
Raj's dashboard, updated Sunday, shows Nimbus diversifying in May.

Reskin of CDC's Variants Nowcast, and any significant variants in GISAID not broken out by CDC.
Five bar-style tree-charts, for fortnights through 5/25–6/7. Legend of last fortnight, organized by subheadings of color-grouped families and convergent clusters. Percentages overlay each color key, reflecting share as of most recent tree-chart.
For 5/11–5/24, packed bubble charts fill single-variant tiles, reflecting GISAID detail not shown by CDC's Nowcast.

Nimbus NB.1.8.1 / PQ is a scion of left-field Razor-Blade-Throat XDV.
Razor-Blade-Throat XDV was a child of Winter 2024's WHO-Vaccine-Target JN.1 and left-field recombinant XDE.
XDE was a child of left-field Hyperion grandkid FL.13.4 and left-field Hippogryph scion GW.5.1.
XFG is a child of April's JN.1.16.1 kid LF.7 and newish FLiRT31 cluster LP.8.1.2.
