It's possible, but I think most market analysts probably don't think the recent downturn has much to do with these rumors, as it's market-wide, not just AI related or even semiconductor only. It's probably more likely because the surprise raise of interest rate by BOJ and thus causing the unraveling of a lot of yen carry trades. Now yen has settled down a bit so people are now rebuilding their carry trade portfolio (after all, even at 0.25% it's still much lower other places), with probably less leverage than before (for smart people anyway, stupid people will always do risky trades).
