European equities were set to open on a downward trend on Tuesday, influenced by rising political instability following the dismissal of French Prime Minister Francois Bayrou on Monday. President Emmanuel Macron must now appoint a new Prime Minister, the country's fifth in less than two years, with expectations leaning towards the selection of another centrist ally. In corporate developments, Dutch chipmaking giant ASML has taken a leading role in Mistral AI's €1.7 billion funding round by investing €1.3 billion, gaining an 11% stake in the French startup. Meanwhile, there are no significant economic data releases scheduled in Europe today. In premarket trading, futures for the Euro Stoxx 50 and Stoxx 600 indices fell by approximately 0.3%.
