When a 33-Quarter Ritual Ends: Alphabet's Capital Machine Shifts Into a New Gear

Alphabet skips buybacks for two straight quarters, redirecting cash to record AI capex and chip sovereignty, while leadership reshuffle spooks markets.

There are moments when a company reveals more through omission than announcement. For Alphabet, the silence came in the form of a missing line item: zero dollars spent on share buybacks in the first quarter of 2026, followed by the same in the second. That marks the first time in 33 consecutive quarters the Google parent has skipped its repurchase ritual — a striking departure from the $13.24 billion deployed in the year-ago quarter, and a $28.31 billion gap versus the first half of 2025.

The pause is not an accident. It is the flip side of a deliberate reallocation: Alphabet has guided 2026 capital expenditures to $195–205 billion, with another step-up promised for 2027. When a company is pouring that much into data centers, chips, and AI infrastructure, there is simply less left over for returning cash to shareholders. The buyback hiatus is the tell — a conglomerate fundamentally rewiring its capital allocation away from shareholder returns and toward a bet on its own AI infrastructure.

A Leadership Reshuffle That Rattled the Market

That restructuring extends beyond the balance sheet. In early August, Jeff Dean — a 27-year Google veteran and most recently Chief Scientist — departed amicably to launch Discovery Loop, with Alphabet joining as founding investor and cloud partner. Around the same time, Demis Hassabis stepped back from day-to-day leadership of Google DeepMind to become Chairman of DeepMind and Chief Scientist of Alphabet, while Koray Kavukcuoglu took over operational control, reporting directly to Sundar Pichai and overseeing Gemini model development.

The market's reaction was visceral: shares briefly fell 4–5%, erasing roughly $190 billion in market value. That may seem outsized for what the company frames as an orderly, consensual transition. But it underscores how jittery investors have become about any movement in Google's AI leadership ranks — precisely when Alphabet is placing its largest-ever wager on AI.

The Chip-Sovereignty Thread

Lay the recent announcements side by side and a pattern emerges. In late July, Alphabet secured contractual rights to acquire up to $12.2 billion in Marvell shares — consideration for chip purchases spanning the TPU ecosystem, AI inference accelerators, and memory controllers. Meanwhile, Waymo's robotaxis now run on a custom ASIC chip, manufactured at TSMC on a 5-nanometer process, delivering more than 1,000 TOPS and reducing reliance on Nvidia. To fund the buildout, Alphabet tapped debt markets in early August with a $25 billion bond issuance, following an Australian-dollar tranche of A$5.5 billion that drew bids exceeding A$18 billion — a 20-year coupon of 6.9% that signals strong long-term credit confidence.

The through-line is chip sovereignty. Alphabet no longer wants to be merely a customer of the big semiconductor houses; it wants to own the technology — in TPUs, in robotaxi silicon, in supply agreements with partners like Marvell.

Waymo's Expansion and the Berkshire Vote of Confidence

The most substantive progress, however, may be in autonomous driving. Alphabet has reportedly opened its newer, lower-cost robotaxi model to all users in Los Angeles, Phoenix, and San Francisco — no longer a pilot but a broad rollout. And in Nevada, the company secured approvals to operate thousands of robotaxis, a sign that Waymo is scaling beyond the demonstration phase.

Independent validation has also arrived from an unlikely corner: Berkshire Hathaway increased its Alphabet stake by 83% in the second quarter to nearly 106 million shares, worth roughly $37.8 billion — including a $10 billion investment announced in June to support AI infrastructure. The Duquesne Family Office also initiated a position of 336,300 shares, according to a 13F filing. Add to that Alphabet's stake in SpaceX, which Reuters valued at approximately $94.2 billion as of end-June against an original investment of around $900 million — a hidden asset absent from any conventional cloud or advertising revenue analysis.

The Risks That Temper the Story

The picture is not without blemishes. The law firm Pomerantz is reportedly investigating potential investor claims against Alphabet. A court has delayed the planned purchase of Spirit Airlines' internal data after union objections — despite Alphabet winning the auction with a $10 million bid against a $12.5 million offer from AI startup Micro1. And reports suggest the next Gemini flagship model could slip into the fall — an execution risk worth acknowledging without overstating.

The share price reflects the tension. Since quarterly results roughly two weeks ago, the stock is down 2.7%; since the antitrust lawsuit just over three weeks ago, it has fallen 8.1%. At €298.55, the shares trade about 2.6% below their 50-day average but remain 3.8% above the 200-day average — a picture of consolidation rather than decline. The stock sits roughly 15% below its 52-week high of €350.75, yet about 70% above last August's low. The most recent session brought a 1.1% gain, with a 3.9% advance over the past 30 days.

That recovery feels fragile as long as the market is uncertain whether the massive investments will translate into commensurate returns — or, as the buyback pause suggests, come at the expense of near-term shareholder value. The defining question for coming quarters is not whether Alphabet invests in AI — that is settled. It is whether the company will resume returning capital to shareholders once the current investment wave crests. Until then, the summer's signature image remains a combination of leadership transition, chip offensive, and suspended buybacks — with Berkshire's outsized bet as the counterweight.
