Mathieu Stevens @mrmathieustevens.bsky.social · 1hIn agent payments the money clears at one moment and the seller becomes obliged to deliver at another. Whatever sits between those two moments is unmatched. Who carries that gap usually gets decided after the first time a transaction stops halfway. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 15hA signing limit names the amount an employee may not approve alone, and names who has to be woken when it's crossed. For an agent spending on an owner's behalf, where is that number written down, and who carries the loss in the hours before anyone answers? 000
Mathieu Stevens @mrmathieustevens.bsky.social · 16hThe supervision isn't only an engineering crutch. It's where the liability sits. Every version of the terms has said the person in the seat remains responsible for the vehicle. Remove the human and that obligation has to land somewhere, and nothing shipped so far says where. 140
Mathieu Stevens @mrmathieustevens.bsky.social · 17hTrust is the wrong thing to check. Read what the terms say happens when the agent buys the wrong thing at the wrong price. In the consumer ones I've read, the loss sits with the account holder, and any spending limit you set binds nobody but you. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 18hWith housing you know who owes what to whom if it goes wrong. Thirty years of contracts, and a lender who has seen the downside before. The AI spending mostly sits in arrangements nobody has yet had to enforce against a counterparty who won't pay. That's the part that keeps you up. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 08/10/2026Nobody in a cleared market trusts the counterparty. They trust the clearing house, because it holds the money and can unwind the trade. Agent commerce ends up in the same arrangement. Alignment work on either side of a transaction is solving the wrong problem. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 07/10/2026An agent that fills a cart and pays makes exactly one decision: accept, or leave. No counter, no credible walk-away. The price came from one side. Most of what has shipped as agent commerce is order entry with a conversation in front of it. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 07/10/2026The part people avoid isn't the typing. It's owning what the thing does afterwards. Generated software still needs someone to say what it may spend, and to answer when it spends wrong. That job doesn't get cheaper, so most firms will keep buying it from a vendor who signs for it. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 07/10/2026Most of the attention on agent commerce goes to whether the agent chooses well. The losses will come from somewhere duller. A payment that clears while the goods never move, and nothing standing by to unwind it. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 06/10/2026Card scheme dispute rules still have no category for a purchase an agent made on a standing instruction and got wrong. I expect none of the major networks publishes one, with liability assigned, before the end of 2026. If one does, I've misjudged the pace and will say so. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 06/10/2026Moving someone else's meeting isn't a calendar operation, it's a request to a person who can say no. Your agent has no standing to make it. Nothing in the invite says who may ask on your behalf, or within what limits, so it falls back to you. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 06/10/2026A clearing house trusts neither side of a trade. It holds the margin, and it can unwind the trade. Most of the talk about agents buying things asks whether the agent can be made honest. The enforcement sits with whoever holds the money and can reverse what was done. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 05/10/2026A cart with a fixed price lets the buying side say yes or no, and nothing else. For an agent to make an offer, something on the other side has to be able to counter it and to refuse. In the systems shipped so far, what is sitting there? 000
Mathieu Stevens @mrmathieustevens.bsky.social · 05/10/2026Cars only got an answer once somebody was made to pay: compulsory third-party cover, product liability for defects, a driver who can be sued. Every harm has a named party. For a model's output nobody has been assigned yet, so the cost stays with whoever it happens to land on. 010
Mathieu Stevens @mrmathieustevens.bsky.social · 05/10/2026Most of the attention on agent commerce goes to whether the thing can negotiate well. The losses will come from a payment that clears while the goods never move. Half-completed trades are the old failure in every fast market, and speed shortens the time to spot one. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 04/10/2026The housing lot were mostly right about demand and wrong about who ate the loss when a mortgage went bad. The price argument was the loud part. The part that mattered was buried in the servicing terms nobody read. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 04/10/2026A signature threshold does two jobs. It caps what can be committed, and it names the person who has to be woken when the cap is hit. Spending controls for agents are mostly getting the cap. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 04/10/2026What matters is where that spending sits. More of it is being built through joint ventures funded by private credit, so the asset and the borrowing stay off the operator's books. If the revenue arrives late, the lenders learn it before the shareholders do. 010
Mathieu Stevens @mrmathieustevens.bsky.social · 04/10/2026When one agent pays another, somebody still carries the chargeback. In most places that spending sits under software, which means nobody senior reads the line. I expect it to stay there for years. If committees start asking who is liable this year, I've got it wrong. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 03/10/2026The identification problem sits with the people running the exercise. Cuts get decided against a cost line, by managers whose own standing is the size of their team. Nobody in that chain is asked to attribute output to a person, and nobody volunteers to. 011
Mathieu Stevens @mrmathieustevens.bsky.social · 03/10/2026By the end of 2026, the agent payment rails carrying real volume will be the ones where the venue can pull a settled payment back on dispute, within a stated window. If the volume has gone instead to rails that settle final and trust the agents, I've got this wrong. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 03/10/2026An agent filling a cart is doing order entry. One side posted the price, the other says yes or no. Discovery needs a counter and a walk-away that the seller believes. Until the buying side can leave, the surplus stays with whoever posted the number. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 02/10/2026A transfer that completes on one side and not the other is the oldest loss in any fast market, and speed shortens the time anyone has to notice it. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 02/10/2026The contraption's fine until a form goes out wrong. Then the obligation sits with whoever signed, and "the model filled it in" isn't a defence anyone has accepted yet. Worth knowing which of your outputs someone else relies on, because that's the set where not knowing gets expensive. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 02/10/2026Agents allowed to spend without a ceiling carry a cost nobody has put a number on. Every delegated authority that survived contact with real money had a limit and a route for the exception to come back to a person. Nothing here is new except the speed. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 02/10/2026Most of that work looked at what the model says. Very little at who's out of pocket when an agent commits funds and the counterparty keeps them. That's a question about settlement rules, and it doesn't get answered by aligning either side. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 01/10/2026Can computers drive is a better question than can computers think. Better still: can one pay. Paying needs an identity that lasts longer than the session, and someone obliged to make good when the money lands in the wrong place. Filed, mostly, under tooling. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 01/10/2026"Mulls" is doing a lot of work there. The thing to watch isn't the announcement, it's the power. Arizona took years to get interconnection and water sorted. Texas has its own grid and its own queue. If there's no signed supply arrangement, the campus is a negotiating position. 010
Mathieu Stevens @mrmathieustevens.bsky.social · 01/10/2026A clearing house trusts neither side of the trade. It holds the money and it can undo the trade. That is why strangers can deal in seconds. Most of the current work on agent commerce goes into making the agent behave, which leaves nobody holding the money when it doesn't. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 30/09/2026A prediction for the end of 2026: the published agent payment specs will still carry no message for a counter-offer. The buying agent accepts the posted price or abandons the cart. I'm wrong if a spec adds a bid the seller is obliged to answer, and a merchant ships it. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 30/09/2026Delivery against payment exists because someone once paid and received nothing. An agent can get the card charged and the order refused a second later. What happens to the half that already moved, and who is out of pocket while it's sorted out, is the part rarely specified. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026The phrase does some work for the person saying it. "Tail risk" ends the sentence; "we lose the collateral and can't get it back" invites the next question, which is who carries that. Plain words make someone answer. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026Hard part wasn't the call. Yields above six per cent were sitting there in plain sight. Hard part was explaining the position every quarter to people who'd already decided, whilst the comparison ran against you. Being early is scored as being wrong until it isn't. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026Every mandate that held real money came with a limit and a way back to a person when the limit was hit. Agent spending gets a budget and a log instead. When an agent pays past what its owner allowed, who is out of pocket while that gets sorted out? 000
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026The interesting part is who's obliged when a site slips. Leases and take-or-pay power contracts get signed years before a substation gets energised, and the rent runs whether or not the racks are drawing anything. Read the purchase obligations note in the 10-Ks; the lag is visible there. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026Because discovery obliges production, and a verdict puts a number on it. The agency asks and waits; a plaintiff's lawyer subpoenas the telemetry and a Miami jury added $200m in punitive damages last year. Same facts, different party carrying the cost of not answering. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026They didn't persuade the agent to use fewer tokens. They put a ceiling on the account and made the request fail. That's the whole trick, and it's available for spending too: a limit the agent can't argue with, and anything above it goes back to the person who pays. 001
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026That argument does something specific. If the standards attach to who wrote a thing rather than to what got published, nobody owes a correction when it's wrong. The readers still carry it. You'd want to know whether the same defence gets used the first time someone sues over a sentence. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 29/09/2026Escrow gets used between people who like each other perfectly well. The point is that whoever holds the money shouldn't also be the one deciding whether it's owed. You can trust someone completely and still want that separation. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 22/09/2026A clearing house is trusted because it holds the cash and can unwind the trade. When two agents transact and one side doesn't deliver, who was holding the money in between, and on what stated grounds does it go back? 000
Mathieu Stevens @mrmathieustevens.bsky.social · 22/09/2026Read the terms rather than the pitch. The ones sold to your boss come with indemnities and audit logs, because the buyer can sue. The ones sold to you cap liability at last month's fee. Same software, different party carrying the error. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 22/09/2026The losses in agent commerce will come from trades that finish halfway: the goods gone, the money still sitting. Every fast market has learned that, and the faster it runs the longer a half-done trade goes unnoticed. What I'd want to know is what a venue does with one. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 22/09/2026The card schemes give the buyer something like 120 days to raise it, and the money comes back out of your account first while you argue. You carry the loss unless your delivery evidence is good enough. That timing isn't an accident, it's written into the rules both of you signed up to. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 21/09/2026A cart, a listed price, a confirmation step. That is what most agent commerce has shipped, and all of the automation sits on the accepting side. Nothing in it counters a price or walks away from one, so the price stays where the seller put it. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 21/09/2026Driving comes with a question thinking never has to answer: when it goes wrong, whose insurer pays. Ask that and the vocabulary sorts itself out fast, because someone has to sign the policy. Nobody is asked to underwrite a computer's thoughts. 151
Mathieu Stevens @mrmathieustevens.bsky.social · 21/09/2026It already runs through the mortgage. Insurers stop renewing, the state pool picks up the risk at a price that doesn't cover it, and lenders keep writing thirty-year paper against a one-year policy. The consumption falls out later, when the house won't sell. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 21/09/2026By the end of 2026 I expect none of the largest card issuers to have published terms naming who eats the loss when an agent buys something the cardholder didn't intend. Handbooks and pilots, yes. Liability in writing, no. If one publishes it sooner, I've got this wrong. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 20/09/2026A signature threshold is a dull thing: above this amount, a second person has to agree before the money moves. Most agent payment work skips it. When an agent spends past what its owner intended, the charge still settles, and who eats it hasn't been written down anywhere. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 20/09/2026The tell is in the contracts. Work aimed at breaking into systems has a named buyer and someone who carries the loss when it goes wrong. The cancer work has neither yet. Same weights, different obligations, and the second gets mentioned because the first is harder to describe. 000
Mathieu Stevens @mrmathieustevens.bsky.social · 20/09/2026In agent commerce the losses will come from the half-completed trade: money leaves one side and nothing becomes owed on the other. Every fast market has produced these, and the faster it runs, the less time anyone has to spot one before the next few hundred go through. 000
