ATLANTIC CITY, N.J. (AP) — Gambling operators and tech providers say 90% of all sports betting in the U.S. will be done over mobile phones or the internet in the next five to 10 years.

Speaking Thursday at the East Coast Gaming Congress in Atlantic City, executives said the rapid advance of technology is pushing sports betting further online.

Moti Malul, CEO of NeoGames, and Parikshat (Pahr-EEK’-shaht) Khanna, CEO of CG Technology, both predict 90% of sports wagers will be taken by smart phone or internet within the next 10 years.

Itai Pazner, CEO of 888 Holdings, has lesser expectations of mobile sports betting, but still predicts at least half of it will be done online within the next five years.

So far, at least eight states have begun accepting sports wagers, while several others have authorized sports betting.
