The milestone comes the day after the head of the World Health Organization (WHO) warned the world was "approaching the highest rate of infection" so far.
India - experiencing a second wave - recorded more than 230,000 new cases on Saturday alone.
Almost 140 million cases have been recorded since the pandemic began.
WHO chief Dr Tedros Adhanom Ghebreyesus warned on Friday that "cases and deaths are continuing to increase at worrying rates".
He added that "globally, the number of new cases per week has nearly doubled over the past two months".
