With the Senedd election one week away on May 7, trader consensus prices Plaid Cymru at a 72.5% implied probability to secure the most seats under the new 96-member proportional representation system across 16 constituencies, well ahead of Reform UK at 27.5%, while Welsh Labour and others languish below 1% amid the incumbent party's historic collapse to around 15% vote share after 27 years governing. A fresh Survation poll for Aberystwyth University places Reform narrowly ahead at 30%-28% in voting intention, tightening the two-horse race, but MRP projections like YouGov's late-April model continue favoring Plaid's seat efficiency in key regions. Plaid's leader has cast the contest as a direct clash of national visions, with no late campaign shocks reported.
