XFP is the latest recombinant variant to be classified and incredibly it is the third of a recent set of recombinants with identical spike mutations. The earlier ones were XFJ and XFM.
I think of them as the "Doppelgängers".

With the LP.8.1.* variant on the way to dominance in most places, it is time to ponder which variant might drive the next wave.
The leading contenders at this point are LF.7.7.2, LF.7.9, NB.1.8.1, NY.9 (new), XEC.25.1, XFG and XFJ.

Then it appeared multiple times on LF.7 backbone but it was successful only on LF.7.9 and LF.7 recombinants (XFJ) in combination with 441R and in this form it managed to circulate until today with RW.1.1 and RF.5/RF.6 reaching 15% of global sequences in the past 5 weeks.

XFJ.* has been growing sharply in North America, mostly driven by RW.1.1.*. It finished at 26% of recent samples, challenging XFG.* which fell sharply to 38%.
RW.1.1 is a sub-lineage of the XFJ recombinant, adding the Spike A435S mutation.

And honestly neither XEC nor LP.8.1* are particularly strong. But also consider that the first XFJ sequence was detected several months ago, so XFJ likely isn’t as strong as was BA.1.

Here's the latest variant picture for the United States, to early June.
XFG.* "Stratus" remained dominant but fell sharply to 39%.
XFJ.* (led by RW.1.1.*) finished at 18%.
JN.1.* + FLiRT (led by RF.5.*, mostly from International Travellers) finished at 18%.
