Bill Gates Just Spent Over $100 Million Buying a Trash Company
Bill Gates and his Cascade Investment bought Republic Services stock on the open market three times in one week. NexusAlert scored the buying in the top 1 percent for insider conviction.
The world’s most famous investor just backed up the truck on a garbage company
On August 20, 2026, a Form 4 hit EDGAR showing Cascade Investment, L.L.C. and William H. Gates III, both 10% owners, buying 359,992 shares of Republic Services on the open market. It was not a one-off. NexusAlert tagged it High severity under Insider Trading, and the Company Dossier shows it was the third Republic Services buy from the same investor in a single week.
Bill Gates is the name everyone knows from software. Republic Services is the name on the second-largest fleet of waste and recycling trucks in America. Those two things collided on the filing, and the buying was aggressive.
What the filing actually says
The Form 4 reports open-market purchases, the plainest bullish signal an insider can send. There is no options exercise dressed up as a buy here, and no shares handed over to cover taxes. Cascade and Gates paid cash for stock, the same way any investor does.
NexusAlert flagged it as an insider-buy event with the tags insider buy, large purchase, ownership increase, and executive purchase, and its AI read the disposition codes so the “buy” label means an actual acquisition, not an accounting artifact.
The misconception worth busting
Here is the trap. The same NexusAlert Dossier that shows the buying also shows a Form 144 on file: planned selling of about $422K. A quick reader sees “planned selling” and assumes there are two sides to this story, buying and selling, that roughly cancel out.
They do not come close. The planned selling is about $422K. The buying runs into the hundreds of millions. And the two are different in kind: a Form 144 and a 10b5-1 plan are a calendar, shares scheduled to sell on autopilot regardless of price. An open-market purchase outside any preset plan is a decision made this week, at this price. One is a schedule. The other is a conviction.
That distinction is the whole game with insider filings, and it cuts both ways. Plenty of scary “insider sold” headlines are just tax withholding at vesting. This one is the mirror image: a tiny scheduled sale sitting next to a wall of discretionary buying.
The bigger pattern the Dossier surfaces
Zoom out from the single filing and the pattern gets louder. The NexusAlert Dossier shows Republic Services with net insider flow of +$339.1M buying across 150 transactions, and the notable Form 4 lines are all the same buyer: Cascade Investment purchases of $45.8M, $36.4M, and $35.7M. Against that, the officer and C-suite selling totals a rounding error, and the planned Form 144 selling is $422K.
The Dossier’s scores put a number on all of it. Republic Services carries an Insider Conviction score of 9.9 out of 10, in the top 1% of every company NexusAlert scores. That sits alongside a Financial Strength of 9.0 (top 10%), Governance of 8.0, Earnings Quality of 7.6, and an above-average overall of 41.5 out of 50. This is not a distressed name that an insider is trying to prop up. It is a strong, cash-generative business that a long-term concentrated owner is choosing to own even more of.
The lesson
A news alert tells you Bill Gates bought a stock. The filing tells you how he bought it, how much, and whether the small “planned selling” line next to it means anything. In this case the answer is that the buying dwarfs everything else, and it was done at market, this week, on purpose.
Read the whole filing, not the headline. That is the entire reason NexusAlert exists: it reads every 8-K, Form 4, and Form 144 the moment it posts, separates a real open-market buy from a scheduled sale or a tax withholding, and scores the insider conviction so you can see when a famous name is actually putting money to work.
