This morning AGL shares jumped 11 per cent, as news of the speculative bid emerged.
It is understood Mr Cannon-Brookes is forking out 20 per cent of the $8 billion, with asset manager Brookfield shouldering the remaining 80 per cent.

AGL's coal plants are thought to be responsible for eight per cent of Australia's total greenhouse gas emissions.
Mr Cannon-Brookes has been a long-time and very vocal critic of Australia's action on lowering carbon emissions.
The bid from Mr Cannon-Brookes and Brookfield would see AGL fast-track the transition away from coal in favour of renewables.
That plan would involve shuttering coal plants much earlier than expected.
The AGL board met to consider the offer on Sunday, and today it was rejected.

Speaking on the campaign trail in Tasmania, Prime Minister Scott Morrison today appeared in no mood to shut down coal plants at a more rapid pace.
"Let me be clear about something, we need to ensure that our coal-fired generation of electricity runs to its life," he said.
"Because if it doesn't, electricity prices go up. They don't go down."
