Fatfish Group (ASX:FFG) shares soared 73.6 per cent yesterday to 9.2c, having gained 155.6 per cent year-to-date.

In response to an ASX price query, Fatfish noted that its Singaporean-based investee company, Smartfunding Pte, had developed a BNPL platform it plans to roll out this week.

“FFG further notes that some ASX listed companies in the BNPL space have experienced recent strong demand and increases in prices, especially company(s) involved in the Asian geographical market,” Fatfish Group said.

IOUpay (ASX:IOU) shares similarly rocketed 59.1 per cent yesterday, and it is up 324.2 per cent since December 31.

In response to a similar ASX price query, IOUpay pointed to its announcement on February 9 about its major partnership for BNPL services in Malaysia.

“This further expansion of the Company into the BNPL sector, further to its existing interests in the mobile and mobile payments sector, is likely to have been recognised by shareholders as being value accretive to IOUpay Limited shareholders by virtue of recent other BNPL market participants’ relative market performance,” IOUpay said.

Last week the BNPL giant hit an all-time closing high of $158.47, and in intraday trading APT shares changed hands at an all-time high of $160.05.
