They include a new stadium, with plans outlined as they completed a £4.25bn takeover in May 2022, and the multi-club model currently involving Strasbourg.
However, there is said to be no guarantee that Chelsea will agree on a deal for investment, and their search is at the exploration stage.
Chelsea have splurged over £600m on players in the three transfer windows since Boehly and Clearlake inherited control at Stamford Bridge from Roman Abramovich.
The west Londoners’ blockbuster deals include a British-record £107m spent on Benfica midfielder Enzo Fernandez in January, £75m on injury-stricken defender Wesley Fofana and £60m on first-season flop Marc Cucurella.
This summer, Christopher Nkunku has arrived in a £52m deal from RB Leipzig, joining £32m Villarreal forward Nicolas Jackson, £39m AS Monaco defender Axel Disasi and starlets Lesley Ugochukwu and Angelo for a £36m fee.
