Stock buybacks are now one of the biggest ways U.S. companies return cash to shareholders. S&P 500 companies spent a record $1.02 trillion on repurchases in the 12 months ending September 2025.
That was up 11.1% from $918.4 billion a year earlier. Combined with dividends, companies returned a record $1.685 trillion to shareholders.
The trend has carried into 2026. Nvidia approved a $150 billion buyback expansion in September 2026, and General Motors announced a new $20 billion program in October 2026.
An authorization is not the same as actual spending. A company can approve $100 billion in future purchases, then spend it over several years or never use all of it.
The latest full S&P Dow Jones Indices release covers the third quarter of 2025. This article uses that data for index-wide totals and treats 2026 company news as a separate measure.
The figures below give a quick view of where buybacks stand. Each one is explained in more detail later in the article.
The $1 trillion mark is the biggest headline. It happened during the 12 months ending September 2025, when buybacks rose 11.1% from the year before.
It was only the second time the rolling annual total passed $1 trillion. The first was the 12 months ending June 2022, when companies spent $1.005 trillion.
Buyback spending now rivals the yearly economic output of a medium-sized country. Few corporate activities reach that size.
The Nvidia and GM figures are company announcements, while the other numbers are completed spending tracked by S&P. Mixing the two would give a misleading picture.

A stock buyback happens when a company buys its own shares from investors. The company usually retires those shares, so fewer remain in circulation.
Here is a simple example. A company has 1 billion shares and earns $10 billion, so earnings per share (EPS) are $10.
If it buys back and retires 100 million shares, 900 million remain. With the same profit, EPS rises to about $11.11.
The company did not earn more money. The same profit is simply split among fewer shares.
Measure Before buyback After buyback Shares outstanding 1 billion 900 million Earnings $10 billion $10 billion Earnings per share $10.00 $11.11This is one reason buybacks can raise EPS and may support a stock price. Shareholders who keep their shares own a larger slice of the business.
Companies choose buybacks for several reasons. They may have extra cash, believe their shares are priced low, or want to lift per-share results.
The choice depends on management’s view of the share price and on what else the cash could do.

Companies return money to shareholders in two main ways. They can pay dividends or buy back shares.
A dividend sends cash straight to shareholders. A buyback uses company cash to purchase outstanding shares.
Buybacks are more flexible. Once a firm starts a regular dividend, investors expect it to continue, and a cut can signal trouble.
Repurchases can be raised, lowered or paused with less market reaction. That flexibility is one reason companies use them when cash is plentiful.
Buybacks now outweigh dividends. In the 12 months ending September 2025, companies spent $1.020 trillion on buybacks and $664.9 billion on dividends.
Together that is $1.685 trillion returned to shareholders. Buybacks made up about 61% of the combined total.
Dividends still matter. They give investors steady income, while buybacks reward those who hold on through a larger ownership share.

The biggest single quarter in S&P’s published series was Q1 2025, at $293.45 billion. Strong earnings and cash flow helped push spending higher.
Companies then pulled back. Q2 spending dropped to $234.57 billion, a fall of 20.1%.
Q3 rose 6.2% to $249.00 billion. That was still above the $226.6 billion spent in Q3 2024.

Buybacks respond quickly to profits, cash levels and market conditions.
Q1 2025 was about 24% above Q1 2024. Q4 2024 was already the strongest quarter of that year at $243.2 billion, so spending was building before the record.
Across the seven quarters in the table, the average was about $246 billion. Only Q1 2025 sat far above that level.

Long-term data shows a clear step up. Annual buybacks were about $519 billion in 2017 and reached about $943 billion in 2024.
Spending rose sharply after the 2017 U.S. corporate tax overhaul. It hit $806 billion in 2018.
The pandemic cut spending to $520 billion in 2020. Companies then rebounded, spending $882 billion in 2021 and $923 billion in 2022.
Spending dipped to $795 billion in 2023. Calendar 2024 set an annual record at $942.6 billion.

From 2021 to 2024, annual spending stayed between $795 billion and $943 billion. That range is far above the pre-2018 level.
The dips are also clear. Spending in 2019 was about 10% below 2018, and 2023 was lower than 2022.

Repurchases are cyclical. They tend to fall hard when the economy weakens.
In Q4 2007, just before the financial crisis deepened, S&P 500 companies spent about $141.7 billion. By Q2 2009, quarterly spending had fallen to $24.2 billion.
That is a drop of more than 80%. Companies chose to hold cash while credit markets were stressed.
The same pattern appeared in 2020. Annual buybacks fell from $728.7 billion in 2019 to $519.8 billion in 2020, a decline of about 29%.
Spending bounced back to almost $882 billion the next year. The record totals of recent years show how quickly companies return to buying when conditions improve.
In the 2007 to 2009 period, Q2 2009 spending was about one-sixth of the Q4 2007 level. Few other corporate budgets fell that fast.

A few firms drive the totals. Apple has shaped modern buyback statistics more than any other company.
Apple spent about $20.4 billion on buybacks in Q3 2025. Over the 12 months ending September 2025, it spent $96.7 billion.
Over five years, Apple spent about $468 billion. Over ten years, the total was about $755 billion.
Apple also held 19 of the 20 largest quarterly buyback spots in S&P’s historical ranking at that time. Meta held the other one.
Nvidia is now a major buyer too. It spent $14.9 billion in Q3 2025 and $51.8 billion over 12 months, up from $34.5 billion a year earlier.
Alphabet spent about $55.8 billion over 12 months, including $11.5 billion in Q3. Meta spent $44.2 billion over 12 months and $8.5 billion in Q3.
Apple, Nvidia, Alphabet and Meta together spent $55.2 billion in Q3 2025. That was more than 22% of all S&P 500 repurchases in the quarter.
Apple’s 12-month total was about 1.7 times Alphabet’s. Nvidia’s 12-month spending rose about 50%, from $34.5 billion to $51.8 billion.
Apple’s cash flow lets it invest in its business, pay dividends and retire shares at the same time.

Technology gets the headlines, but financial firms are also large buyers. Together, the two sectors made up almost half of all spending.
Information technology spent $70.6 billion in Q3 2025, or 28.4% of the total. Over 12 months, it spent $281.6 billion, or 27.6%.
Financial companies spent $65.3 billion in Q3 2025. That was up 26.3% from the prior quarter and 48.2% from a year earlier.
Over 12 months, financials spent about $218.6 billion. JPMorgan alone spent $27.6 billion of that.
The trend continued in 2026. Goldman Sachs bought back about $4 billion of its shares in Q2 2026 and paid another $1.36 billion in dividends.
Technology and financials together spent $500.2 billion over 12 months. That is about 49% of the $1.020 trillion total.
Communication services ranked third at $146.1 billion. Energy was the smallest of the seven sectors shown, at $59.4 billion.

Hundreds of companies buy back shares, but a small group does most of the spending. The top 20 repurchasers made up 49.5% of Q3 2025 buybacks.
The historical average for the top 20 is about 47.8%. Before the pandemic, it was lower, at around 44.5%.
This matters when reading trillion-dollar headlines. The average S&P 500 company is not spending billions each quarter.
Still, buybacks are widespread. In Q3 2025, 387 S&P 500 companies reported at least some repurchases, and 333 spent at least $5 million.
Over the 12 months through September 2025, 436 companies bought back shares. Repurchases are a standard tool across corporate America, not only in Big Tech.
In other words, the top 20 firms spent about half of the total. The rest of the index shared the other half.

Not always. A company can spend billions on buybacks without much change in its share count.
The reason is that companies also issue new shares. They do this through employee pay, stock options, restricted stock units and acquisitions.
Part of each buyback simply offsets that new issuance. The dollars spent and the real drop in shares can be very different.
In Q3 2025, only 17.1% of S&P 500 companies cut their diluted share count by at least 4% year over year. Diluted share count is the number used in EPS calculations.
When shares do fall, EPS rises even if profit is flat. If earnings grow 5% and shares fall 3%, EPS can rise about 8%.
That can help a company meet per-share targets. The effect is real, because remaining shareholders own more of the firm.
A useful review looks at two numbers. One is the dollars spent, and the other is the actual drop in shares outstanding.
Price still matters. A buyback adds value when shares are bought below their worth. If a stock worth $100 is bought at $70, remaining holders gain, but buying at $150 can destroy value.

The Inflation Reduction Act added a federal excise tax on buybacks made after December 31, 2022. The tax is generally 1% of the fair market value of net repurchases by covered U.S. public companies.
S&P estimated the tax cost at about $2.25 billion in Q3 2025. That cut aggregate S&P 500 operating earnings by 0.36%.
Over the 12 months ending September 2025, the effect was about 0.40% of operating earnings. S&P concluded the tax had not materially changed repurchasing behavior.
Tax measure Figure Tax rate 1% of net repurchases Q3 2025 estimated cost $2.25 billion Q3 2025 effect on operating earnings 0.36% 12-month effect on operating earnings About 0.40%Record spending since the tax took effect supports that view. Companies appear to treat it as a small cost.
The tax is based on net repurchases and is paid by the company, not by individual shareholders.
At 1%, it is small next to the cost of the shares themselves. A $10 billion buyback would carry roughly $100 million in tax.
New programs in 2026 show that large buybacks continue. Nvidia’s board approved another $150 billion of repurchase capacity in September 2026.
That brought Nvidia’s total available authorization to about $235 billion. Reports say this is larger than the market value of about 84% of S&P 500 companies.
General Motors announced a $20 billion program in October 2026. It shows buybacks matter outside Big Tech as well.
The new Nvidia approval is about 64% of its total available authorization. GM’s program is smaller, but it is large for a company outside the technology sector.
These are authorizations, not completed purchases. Companies can spread them across many years.
S&P also runs the S&P 500 Buyback Index, which tracks the 100 S&P 500 stocks with the highest buyback ratios. As of August 2026, financials were about 30.1% of the index, consumer discretionary 17.4% and information technology 16.7%.
Top holdings included Salesforce, Gartner, Workday, Newmont, Adobe, Airbnb and major refiners. The index ranks firms by buybacks relative to size, so the biggest dollar spenders are not always on top.
One open question is AI spending. Tech firms are putting large sums into data centers, chips and power, yet many still run big buyback programs.
Strong free cash flow lets firms like Nvidia, Apple, Alphabet and Meta do both for now. If AI costs keep rising, they could limit the cash left for repurchases.

Buybacks are a trillion-dollar part of U.S. markets. S&P 500 companies spent $942.6 billion in 2024, then set a quarterly record of $293.5 billion in Q1 2025.
By September 2025, rolling 12-month spending reached $1.020 trillion. Technology and financial firms made up almost half of it.
The activity is concentrated. Apple alone spent $96.7 billion over 12 months, and the top 20 firms made up 49.5% of Q3 2025 spending.
Headline numbers need care. A $100 billion authorization does not mean $100 billion was spent, and only 17.1% of companies cut diluted shares by at least 4%.
A buyback is not automatically good or bad. Its value depends on the price paid, the firm’s finances and whether the cash could earn more elsewhere.
When reading buyback news, a few checks help. Each one separates headline size from real effect.
What is clear is the scale. Trillion-dollar years may become common rather than rare.
