Zoom just announced that webinar calls can now support up to one million simultaneous participants. This is happening after various political groups used the video conferencing platform to raise money for Vice President Kamala Harris’ election campaign, often by hosting calls with hundreds of thousands of people.

The company now offers various tiers to accommodate large events. Customers can choose from webinars that feature max capacities of 10K, 50K, 100K, 250K, 500K, and, of course, 1M attendees. These are single-use webinar packages that come with support from Zoom’s Event Services team to ensure a “professional, engaging experience” for all.

“Now event organizers have the flexibility and power to host truly interactive experiences on an unprecedented scale and the ability to purchase large single-use webinars,” said Smita Hashim, chief product officer at Zoom.

Despite being recently used for political fundraising, Zoom envisions a future in which these large-scale virtual events are common across the enterprise, entertainment and public sectors. The company says, for instance, that celebrities and entertainers can use these webinar capabilities to host fan meet-and-greets and other kinds of virtual events.

These events, however, don’t come cheap. Booking a one-time webinar for a million people will set you back a cool $100,000. That’s actually a good deal, as a webinar for 10,000 people costs $9,000, which is almost a dollar per person.

Before this change, Zoom only offered official support for up to 100,000 attendees. However, reporting by Bloomberg indicates that the company recently changed course so as to accommodate the aforementioned fundraising events.

This all started in July when an organization called Win with Black Women held a Zoom call with more than 40,000 attendees in which they raised $1.5 million for the Harris campaign. This was followed by White Dudes for Harris, with 190,000 attendees, and White Women for Harris, with 164,000 attendees.

This could be a lucrative new revenue source for Zoom. After all, it wasn’t so long ago that its stock sold for $560 per share before dropping to around $60 per share. This rapid decline was expected, as the world moved on from virtual meetings and started going outside again.
