So conclave seems to have good information security, no leaks

These elections are notoriously secret, any guesses were just from what the media spoke of as 'fan favorites'.

Besides, it's explicitly against their law to do these kinds of bets, so anyone who would bet on Polymarket wouldnt be electing a new Pope

Since cardinals are locked there and I imagine don't have phones, the only people who could leak some information would be the Swiss Guard?
