The picture of affluence became clearer as MPs concluded the vetting of the team on Sunday.
Top on the list is Hassan Joho, the nominee for Mining and Maritime Affairs, who said he was worth Sh2.3 billion.
Those with other bigger portfolios included Aden Duale (Sh980 million), Education CS nominee Julius Ogamba (Sh790 million), Kipchumba Murkomen (Sh620 million), and Wycliffe Oparanya (Sh600 million).
While he was yet to make the disclosure at the time of going to press, Justin Muturi (Public Service) had said in 2022 that he was worth Sh700 million.
For his part, Joho told MPs his wealth was drawn from developed and undeveloped property, listing homes in Mombasa, Vipingo, Malindi and Nairobi.
He also has shares in property holdings, family businesses, valuables and cash at bank.
“This is just my share and not that of the family,” he said.
Joho's wealth levels has often been a subject to speculations as he is said to be among the key financiers of the Raila Odinga-led Orange Democratic Movement party.
On Sunday, Suna East MP Junet Mohamed, one of Joho's friends, described the former Mombasa governor as a lover of "finer things" in life.
Joho did not rebut the description during his vetting.
Duale is the second richest, having declared his net worth as Sh980 million.
He listed assets in Garissa and Nairobi including land, houses, a cattle ranch in Garissa, as well as rental property in the two towns.
Duale said he has shares in family-owned businesses, breeds camels and cattle, and has a fleet of motor vehicles.
He also disclosed that he earned good revenue from the sale of his autobiography titled ‘For the Record’.
Duale’s wealth grew by Sh129 million in 21 months from the Sh851 million he disclosed when he was nominated to the Defence ministry in October 2022.
Following closely is the Education CS nominee Julius Ogamba, a lawyer by profession who was among the surprise entrants into the new Ruto team.
He told MPs that he was worth Sh790 million, being largely land, tea, trees, vehicles, farm equipment and income from the law firm.
Interior and National Administration Cabinet Secretary nominee Kithure Kindiki placed his net worth at about Sh694 million.
He cited two homes, one in Nairobi and another in Tharaka Nithi, and vehicles of about Sh17 million.
“I have land and buildings worth about Sh235 million. My two homes are worth Sh190 million,” he told the Moses Wetangula-led committee.
Kindiki also listed savings in SACCOs and banks, adding that he earns from legal practice too.
Close to the Interior CS nominees’ wealth was Murkomen, who is heading to the Sports ministry from Roads.
He said his net worth was at Sh620 million, being a growth of Sh70 million from the disclosure he made 21 months ago.
"I took a mortgage of Sh40 million and invested it. Besides that, my assets have generally appreciated by about Sh20 million," he said.
Murkomen said he had other earnings from farming that added him about Sh10 million during the period under review.
Oparanya who is tipped for the Cooperative CS role said his net worth was about Sh600 million comprising buildings and residences.
Energy CS nominee Opiyo Wandayi, a new entrant in the Cabinet league, also ranked as fairly endowed financially, putting his net worth at Sh530 million.
Wandayi, who was until his nomination Ugunja MP, said his wealth portfolio includes cash, real estate and farms.
"I have a farm in Siaya, Narok and some plots in Kitengela, Migori and Nairobi," he said.
State officers are required by the Public Officers Ethics Act to declare their wealth before resuming office and once every two years.
The vetting was without key events as MPs put the nominees to task over their performance in past postings and political utterances.
Joho was put to task over concerns about his academic qualifications and businesses, which he clarified.
He was also tasked to explain how he’d work with President Ruto after criticising him heavily on political platforms.
The same was put to Raila’s allies who are joining the Cabinet including Wandayi, Oparanya and Mbadi.
Mbadi was tasked to explain his plan for the battered economy even as Wandayi faced criticism for his earlier stance on policies by the Energy ministry.
Murkomen was equally pressed hard on his display of opulence and why many infrastructure projects have stalled.
But it is the wealth audit that took centre stage for most of the nominees, especially those who were getting a second bite of the top jobs.
Davis Chirchir, the Roads, Transport and Public Works CS nominee, put his net worth at Sh509.8 million.
The nominee said he had “a small increase” of wealth by Sh27.6 million during the period he served as Energy CS.
Chirchir said he has a house in Spring Valley (Sh95 million), properties in Westlands (Sh50 million), vehicles, money in bank accounts and investments in the tea sector.
In October 2022, Chirchir told the vetting committee that he was worth Sh482.2 million.
Tourism and Wildlife CS nominee Rebecca Miano revealed that her net worth was Sh444 million.
During her last vetting in September 2022, the nominee was worth Sh397 million, saying the new figure was from a reevaluation.
"I have not increased the assets, what I have done is to revalue modestly the properties taking into account the appreciation," she said.
Miano was Trade CS from October 2023 to July 11, 2024, when President Ruto dissolved his maiden Cabinet.
Ruto’s nominee for Treasury CS John Mbadi said he was worth Sh380 million listing assets of Sh437 million and liabilities of Sh57 million.
“The only deferred income investments which I have is with ICEA of about Sh6 million and the MP pension," he said.
Labour Cabinet Secretary nominee Alfred Mutua said his net worth has increased by Sh42 million since his last disclosure.
When he appeared for vetting in 2022, the CS nominee declared his net worth was Sh420 million.
Mutua said he owns land, hotels, businesses and a few apartments, adding that his net worth was Sh200 million before he was Machakos governor.
Trade Cabinet Secretary nominee Salim Mvurya’s net worth grew by Sh38 million in the last two years.
Mvurya told the vetting committee that he was currently worth Sh158 million, attributing the growth to the value of a property he just completed.
Agriculture Cabinet Secretary nominee Andrew Karanja put his net worth at Sh214 million, saying it comprised his family residences.
"We have apartments, vehicles, plots and lands, and deposits in bank accounts," he said.
Water CS nominee Eric Muuga said his net worth was Sh31 million including lands, and coffee, tea, bananas and miraa farms.
The nominee surprised the vetting team when he disclosed that he doesn’t own a car.
Lands CS nominee Alice Wahome said she was worth Sh327,650,000, saying wealth is shared with her husband.
Wahome, when she was first vetted to join the Cabinet, said she was worth Sh218 million.
Debra Barasa, who is taking up the Health docket, said her net worth was Sh455 million, also jointly owned by her husband.
