Alphabet spent $51.4 billion on equipment last quarter, mostly to buy computing power for artificial intelligence [1][5]. The company posted negative cash flow of $9.1 billion and bought back zero shares, against $39.8 billion of stock retired in the first nine months of last year [1]. So far this year it has raised $42.9 billion of common stock, $19.1 billion of preferred stock and $85.2 billion of debt, $28.7 billion of it senior notes in the third quarter [1]. Its CFO blamed an $8.2 billion fall in other income mainly on one holding, the SpaceX stake [5]. For your portfolio, that buyback gap is the trade. The exit clears at $0, into a market where the company issues stock instead of buying it, which pushes the de-risking trade out of sight.

The big picture:

I read the filings side by side this week, and the same funding shift dominates the pages. A buyback is the quiet half of an equity grant. It retires about as many shares as vesting creates, so covering the tax bill used to leave the share count flat. Alphabet retired $39.8 billion of stock in the first nine months of 2025, yet it bought back nothing in the same stretch of 2026 [1]. The count rose from 12,088 million to 12,294 million, up 1.7% [1]. Holding beats selling only above one growth rate, and a hold-versus-sell model computes it.

Amazon shows the same shift. Over twelve months it collected $168.3 billion in cash and spent $215.2 billion on equipment, which leaves a $46.9 billion gap by my subtraction [2]. In the quarter it spent $77.3 billion on equipment, against $35.1 billion a year earlier [2]. It borrowed $115.1 billion long term in nine months, and $48.1 billion of that landed in the last three [2]. The case for holding the stock once rested on cash the company could hand back, but now it rests on lenders.

The regulator opened a second door at the same moment. On September 30 the Securities and Exchange Commission (SEC) proposed rules to open private markets wider [3]. The package covers interval funds, pools that buy back only a slice of their shares each quarter. It also asks whether a credential should be enough to become an accredited investor, the ticket for buying private funds [3]. The named credentials include an accountant licence, a Chartered Financial Analyst charter and a planner certification [3].

The SEC chair framed the plan around savers’ “post-tax, pre-retirement dollars” and tied it to an executive order on alternative assets inside 401(k) plans [3]. That is the account most holders reach for when they want the spread they think they lack.

The same day showed the door’s other side. The SEC charged a fund adviser and its chief executive over funds holding SpaceX and other shares of companies not yet public [4]. The complaint says the firm sent statements that inflated account values [4]. It also says one fund lost “nearly $3,000,000” after the defendants ignored a capital call, a cash demand a private fund makes on investors [4].

By the numbers

  • −$9.1 billion — Alphabet’s quarterly cash flow: negative for a second quarter running, after $(5.9) billion in the second quarter and a positive $24.6 billion in the last quarter of 2025; twelve-month cash flow is $19.7 billion against $159.8 billion of capital spending [1].
  • $0 — Alphabet’s buybacks: zero bought back in the quarter or in nine months, against $11.5 billion and $39.8 billion a year earlier, while the share count rose 1.7% [1].
  • $46.9 billion — Amazon’s spending gap: cash from operations of $168.3 billion over twelve months against $215.2 billion of equipment, with $115.1 billion of long-term debt raised in nine months [2].
  • $75,000 — the 2027 savings cap: Milliman’s final estimate for the annual addition limit, about $3,000 above this year, and the Internal Revenue Service (IRS) has not published the figure yet [6].

What I’d watch:

What I am watching next is how the tech giants handle their own single-stock bets. Alphabet’s SpaceX position is what one holding looks like when it moves, and its purchase commitments run for years before any of that spending pays off [5]. The company raised common stock, preferred stock and debt while sitting on $265.1 billion of cash and securities [1].

  • The retirement channel: the chair named 401(k) accounts as the target for alternative assets, and that is where most holders keep the money they already think is diversified [3].
  • Capital calls: a call is a cash bill that arrives whether or not the fund’s stated value has moved, and ignoring one is how a position gets lost [4].
  • The debt line: Amazon’s nine-month borrowing and Alphabet’s jump from $46.5 billion to $125.1 billion of long-term debt both fund spending that no longer fits inside cash from operations [1][2].

The catch

None of this is a cash shortage. Alphabet closed the quarter with $265.1 billion of cash and securities and took in $42.3 billion of cash from operations, so the negative figure reflects where it chose to put money, not a strained balance sheet [1]. One quarter of zero buybacks can reverse, and the filing states no intention either way [1]. The fraud case targets one adviser rather than rendering a verdict on interval funds, and the proposal may change before it is adopted [3][4].

Where I’ve landed, after those caveats, is narrower. The two routes out of a single-stock position no longer differ much in what they own. They differ in how often the price is set, and only one of them can send a bill.

The index is not the escape either. Its ten largest members were 40.7% of the Standard & Poor’s 500 at the end of 2025 [7]. That compares with a band of about 18% to 23% from 1990 to 2015, while those ten were expected to earn about 32% of its profits [7]. At midday on October 29 the Nasdaq Composite was down 1.17% and the broad index down 0.27% [8]. A sleeve that holds those ten names is a lighter version of the same bet.

At a glance

The shift: Alphabet’s buyback went to zero while it sold stock and borrowed, so the shares an award creates now dilute holders instead of being retired. The number: $0 of buybacks in nine months, against $39.8 billion a year earlier. The risk: the private funds opening to smaller investors are priced quarterly and can lose a position on a capital call.
