India have become only the second team in cricket history to occupy the No 1 spot across all three formats after defeating Australia in the first ODI on Friday.
India moved past arch-rivals Pakistan to take the top position in the ODI rankings as a result of their latest victory, just before they host the World Cup.
They were already No 1 in Tests and T20Is.
Only South Africa in 2012 have previously achieved the feat.
India’s five-wicket victory over Australia in Mohali took them to 116 rating points, one ahead of Pakistan.
But the hosts could slip down the table if Australia – on 111 points – win the remaining two matches in the series, a warm-up for the World Cup.
If India win the series, they will head into the showpiece tournament as the world’s top-ranked ODI team.
India, who last week won their eighth Asia Cup title by thrashing Sri Lanka in the final, were in top form as they registered a comfortable win over Pat Cummins’ team.
Mohammed Shami claimed five wickets to restrict Australia to 276 before half-centuries from Ruturaj Gaikwad, Shubman Gill, KL Rahul and Suryakumar Yadav sealed the win for the home side.
