The 66-year-old has a break clause in the 18-month deal he signed last December in the event Albion finish in the bottom three, a prospect that seems probable with the club 10 points off safety with only four matches remaining.
While Allardyce is acutely aware of their predicament heading into Sunday's trip to Arsenal, he would not be drawn on his plans beyond the end of the season until second-bottom Albion's fate becomes known.
“There's no definite update," he said. “I wouldn't tell you even if I knew myself. I wouldn't tell anybody. What's happening with myself is undecided just yet, I suppose next week we'll have more in-depth discussions.
“When there's been some planning done, it's on whether are we going to be in the Premier League or the Championship. That will probably need to go a little bit deeper and farther after the Arsenal game.
“I was hoping there would be no need to speculate about my future because we'd already secured our Premier League status but that's obviously not the case."
