Retirement Benefits [Abstract]
Retirement Plan [Text Block]	Retirement PlanThe Company has a trusteed, noncontributory Employee Stock Ownership Plan (ESOP) for the benefit of eligible employees. Since the Company’s common stock is not traded on an established securities market, the ESOP includes a put option for shares of the Company’s common stock distributed from the ESOP. Shares are distributed from the ESOP primarily to separated vested participants and certain eligible participants who elect to diversify their account balances. Under the Company’s administration of the ESOP’s put option, if the owners of distributed shares desire to sell their shares, the Company is required to purchase the shares at fair value for a specified time period after distribution of the shares from the ESOP. The fair value of distributed shares subject to the put option totaled $1.0 billion and $661 million as of March 29, 2025 and December 28, 2024, respectively. The cost of the shares held by the ESOP totaled $4.3 billion and $3.9 billion as of March 29, 2025 and December 28, 2024, respectively. Due to the Company’s obligation under the put option, the distributed shares subject to the put option and the shares held by the ESOP are classified as temporary equity in the mezzanine section of the condensed consolidated balance sheets and totaled $5.3 billion and $4.5 billion as of March 29, 2025 and December 28, 2024, respectively. The fair value of the shares held by the ESOP totaled $13.7 billion and $12.9 billion as of March 29, 2025 and December 28, 2024, respectively.
