NVIDIA's Record $150 Billion Buyback Bets the House on AI — Is the World's Biggest Company Buying Itself on the Cheap, or Running Out of Places to Invest?

Shares ticked higher as NVIDIA dropped the largest share repurchase authorization in U.S. corporate history — $150 billion added in a single stroke. The move lifts the remaining buyback pool to $235 billion , a sum that equates to roughly 4.3% of NVIDIA's ~$5.5 trillion market value . For shareholders, the message is unmistakable: management believes its own stock is underpriced relative to the cash it expects to generate from the AI spending wave.

  • The Numbers Dwarf Every Rival — Including Apple

The increase surpasses Apple's $110 billion authorization in 2024, previously the record.

NVIDIA repurchased about $34 billion in fiscal 2025, over $40 billion in fiscal 2026, and $39 billion in just the first half of fiscal 2027. Yet completing the full $235 billion by January 2028 implies purchases of roughly $44 billion per quarter — more than double the recent quarterly run rate of ~$20 billion. Whether the company actually accelerates that aggressively will signal how truly confident it is versus how much of this is optically friendly board math.

  • A Cash Machine Big Enough to Back the Promise

Trailing twelve-month free cash flow — the money left after running the business and buying equipment — hit $127 billion as of July 2026, up 76% year-over-year.

Over that same period, NVIDIA earned $193 billion in net profit on $303 billion in revenue. That torrent of cash is what makes the buyback credible, not aspirational. Even at full pace, it would consume less than half of annual free cash flow, leaving room for R&D and dividends.

  • The Valuation Case Management Is Quietly Making

NVIDIA trades at a forward price-to-earnings ratio — stock price divided by expected future earnings — of roughly 19–24x , while Apple trades at about 36x its expected earnings. Every dollar NVIDIA spends on its own stock buys more than twice the expected earnings that Apple's buybacks do. Jensen Huang is effectively telling Wall Street: the stock is a bargain relative to where profits are headed.

  • The Unspoken Risk: What If AI Spending Slows?

Combined hyperscaler capital expenditure is projected to exceed $1.3 trillion by 2027 , but those plans are pledges, not contracts. AMD's chips have attracted interest from major cloud providers seeking diversification , and many large cloud companies want in-house chips to lower long-term costs. If big customers pull back or shift spending, NVIDIA's cash engine slows — and a massive buyback becomes a drag rather than a gift.
