there are some rules that are pretty wild wrt. the financing but its all secret.Nonesence. The race can hold more.
It's just that the money would be split to more teams and to an extent it can be argued that the value of the team brands is higher if it is more exclusive
what we know is that ferrari gets a big cut of the top (5% i think) which is going to be changed for the new concorde agreement as joe saward has reported
williams is also getting a heritage payment but not as huge as the ferrari one
merc and rbr is getting a performance payment because of their long runs of form recently
if they change the rules so that a new team has to pay a lot to get in to the sport and then has to run for a year or two without getting prize money you will eliminate asset flippers who now theoretically could pay the 200m (usd or euro i forget) dilution fee for an entity that could be valued at 1 billion
so if the fee is 600m and you dont get prize money at the beginning, it *should* bring more serious entrants
andretti saying he is ready for 2026 with a new bespoke engine from cadillac is not sensible, but if he buys alpine he could run with renault engines badged as cadillac and then get the real deal in when its ready in 2027 or 2028
