Yes, they are about around 7 hours. The win probability isn't anything in cricket. It only requires 2 balls for Australia to make a comeback. You'll see 96% in favour Australia if India loses 2 or 3 wickets.
I of course was awake when this was posted and checked what time the game started. When I saw it was 4am et I thought oh well I am not going to be live betting that and then I learned today that these matches are a full day affair.
I once went to a 6 hour baseball game and as much as I love baseball it was excruciating near the end of it. I don't know how people watch an 8 hour game.
On my television it's showing that 66.8 crore (660.8 million) people are watching at the moment. Can you believe it?
Cricket is the most watched sports by far.
And this is just for one country. Now include Australia, Pakistan, Bangladesh, Nepal, and many other nations watching on other streaming service or channel. And also include millions of Indians living abroad. All of India's matches are watched by at least a billion people.
