Based on everything I have currently in my database, the House, Senate, Statewide races, and the largest contributing PACs, here is who my data shows as the 20 largest individual contributors to the 2018 Texas election cycle, giving over $23 million combined. #txlege 
Green is ET World, Red are donors who primarily give to Republican candidates. If someone gave to PACs, and also directly to candidates, all dollars are captured and rolled together. I'm still adding some PACs in, so the totals might flex some, but likely not dramatically.
In case you were wondering where the other 3 members of the ET9 fell into the individual rankings:
28 - Holloway Frost - $420k
29 - Dick Saulsbury - $415k
114 - Monty Bennett - $100k (but this doesn't count his MJB Operating, which gave another $117k)
