There is a filing due before the market opens on Monday, November 2, and most of Wall Street will read it as a straightforward earnings check. It is something more useful than that. It is a real-time demonstration of what patient capital actually looks like, how much it earns, and when patience crosses the line into a drag on returns.
Berkshire Hathaway (BRK.B) is expected to report third-quarter results before the open on Monday. Analysts following the company have been looking for third-quarter revenues around $97.3 billion and earnings around $5.91 per share. The number that will move the stock is not the earnings figure. It is whatever Abel has done with the cash.
What the Mountain Earns
Berkshire ended Q2 with $359.2 billion in cash, cash equivalents and U.S. Treasury bills, net of payables for unsettled purchases. That figure was below the end-of-March headline level that drew attention earlier this year, and the reduction reflected real activity. In the second quarter, Berkshire repurchased about $4.5 billion of its own shares and was a net buyer of equities by nearly $20 billion.
Here is the part that rarely gets enough attention. With 3-month Treasury bill yields around 4.1% lately, a $359.2 billion pile can be expected to generate roughly $14.7 billion of interest income on an annualized basis, or about $11.6 billion after a 21% federal tax rate. That is not a rounding error. It is a meaningful earnings stream that arrives whether Abel deploys a single dollar or not.
Buffett long preferred Treasury bills to longer bonds: when rates are low, long bonds do not pay enough for the risk of rates rising, and when rates are high, bills capture most of the yield without that duration risk. Abel has inherited that discipline along with the pile itself.
The Correction Changes the Calculus
Investors dumped big tech stocks following a string of disappointing earnings reports, putting the Nasdaq 100 into correction territory, down more than 10% from its most recent peak. The pressure has been concentrated in large-cap tech names and adjacent software stocks, where investors have been re-evaluating spending and cash-flow expectations.
The tech selloff driving that correction has its own internal logic. Microsoft’s Azure results show how AI infrastructure debt concerns are weighing on large-cap tech valuations even when underlying growth beats expectations.
This is precisely the environment the cash pile was built for. A stock market correction or economic downturn that broadly lowers valuations would create opportunities for Abel to use Berkshire’s cash at attractive terms. Monday’s filing will reveal whether he saw any of those opportunities materialize during Q3, and how the cash balance looks heading into what is now a meaningfully cheaper market.
The Lesson for Your Own Portfolio
While Berkshire has erased some of its 2026 underperformance against the S&P 500, one persistent headwind has been the sheer size of the cash reserve earning T-bill yields while the market rallied hard. That is the honest tension at the center of this story: cash is not free to hold when equities are rising.
The model worth borrowing is not the size of the reserve. It is the structure. Berkshire does not hold idle cash in a low-yield savings account. It rolls short-dated Treasuries, captures near-market yields, and retains the flexibility to act within days. Individual investors can replicate the logic on any scale, using money-market funds or short-term Treasury ETFs rather than letting cash sit and lose ground to inflation.
The cash is there to buy assets. If Abel found an extremely attractive opportunity to make a very large acquisition, he would not pass on it because it meant less income from Treasuries. That is the distinction between strategic liquidity and fearful inaction. The first earns while it waits. The second just waits.
What Monday Reveals
Abel made significant moves in Q2, but with hundreds of billions still available, the bigger question of how aggressively he will spend Berkshire’s fortune remains open. With the Nasdaq 100 now in correction and tech valuations compressing fast, Monday’s Q3 filing lands at an unusually instructive moment. A further drawdown in the cash balance would signal Abel sees value. A steady balance would mean he does not, yet.
Either answer tells you something about where risk-adjusted opportunity sits right now. That is worth more than the earnings number.
