Best case for them is TSMC continues to be heavily capacity constrained for the next few years, handicapping AMD's ability to pick up significant market share while Intel resolves their fab issues. Intel may also have to heavily lean into backporting new designs that have been sitting on the shelf waiting for new nodes. 14nm is finally moving past Skylake-based architectures with Rocket Lake, and there should be opportunities to backport 7nm designs to 10nm as well. Not ideal, but if they can remain roughly competitive with AMD and just out-ship them, that could get them through the next few years without losing much market share.
A US government injection of cash to Intel's fab business seems like it could get bipartisan support if Taiwan/China continue to lead the market, but Intel's problems don't appear to be be cashflow related.
