The former NFL star is believed to have submitted a proposal to buy a 10 per cent stake in the Sin City team and a source has told the NFL Network that the plan is "on its way to approval".
The report suggests Brady's role as a limited partner could be voted for within the next few weeks and the deal is expected to be finalised by the end of 2024 season.
Another report published by The Washington Post suggests the deal with Brady is likely to go through because he is "good for the league".
The insider told the publication: "The deal is 'not done yet. I see it getting done … I think it’ll get there because Brady’s good for the league.
"[The owners would ] like to see it happen' because of Brady’s stature."
Talks around a Raiders deal with Brady have been going on since last year as the sports star stepped away from life on the field to retire and he's already a part owner of the Las Vegas Aces - a basketball team which is also owned by Raiders boss Mark Davis.
Brady's new role as a sports commentator for FOX is believed to have slowed the deal-making process as it he will have to abide by restrictive conditions when acting as a broadcaster to ensure fairness.
NFL insider Ian Rapoport previously reported: "Sources with direct knowledge of this situation said that many of the issues such as the valuation and Brady's role as a FOX broadcaster have been addressed and worked through - and are now in a much better place ...
"Brady will buy a piece of the Raiders knowing that it limits his ability for access to do his job broadcasting for FOX. Brady's restrictions include not being allowed to be in another team's facility, not watching practice and no participation in production meetings.
"His entire production team would be in the meetings, however."
