Nvidia Authorises $235bn of Buybacks While Its Cash Flow Is Falling

The board raised Nvidia's buyback authorisation by $150 billion to $235 billion, implying about $15 billion a month against average free cash flow of $11.6 billion. Quarterly cash flow has more than halved since the first quarter.

Nvidia's board raised the company's share buyback authorisation by $150 billion to $235 billion on 28 September, with the money expected to be used by January 2028.

Spread across that window, the authorisation implies roughly $15 billion a month. Nvidia's average free cash flow over the six months to July was $11.6 billion a month.

The gap, and the reasons it may not matter

An authorisation is permission to buy, not a commitment to buy, and boards routinely approve headroom they never use. Nvidia can suspend the programme at any time. The company's actual pace last quarter was $19.7 billion, or about $6.6 billion a month — well under the implied run rate.

It also has the balance sheet to close a gap if it chooses. As of July it held $56.6 billion in cash and debt securities, plus $42.8 billion in further holdings. The chief financial officer has said Nvidia plans to return 50 percent or more of free cash flow, against roughly 60 percent returned so far this year — which reads as a signal that the payout ratio is more likely to come down than up.

The number that deserves attention is neither the authorisation nor the buyback. It is the direction of the cash flow behind them. Nvidia's free cash flow fell from $48.6 billion in the first quarter to $21.3 billion in the second, a decline of more than half in three months.

Why the world's most-watched balance sheet is a local matter

Nvidia's capital allocation is one of the few reliable public readings on whether the AI capital cycle is still expanding. Data centre build-out across Africa — including the projects being announced in East Africa — is financed on the assumption that compute demand keeps compounding. A large buyback authorisation is a board saying it has more cash than obvious things to build with it. A falling cash flow line under that authorisation is the more interesting signal, and it points the other way.
