What happened

Techmeme surfaced Anthropic’s April 24, 2026 post, Project Deal: our Claude-run marketplace experiment, as a concrete example of agent-to-agent commerce moving out of theory and into something closer to a real market.

Anthropic set up a one-week internal classified marketplace for 69 employees in its San Francisco office and let Claude agents negotiate on both sides of each transaction. Employees told Claude what they might want to buy or sell, gave it some constraints and style guidance, and then stepped out of the loop. Each participant got a $100 budget, the agents ran across parallel Slack channels, and any deal reached by the agents was later honored by the humans in person.

Techmeme 20260423 Bad Connection Uncovering Global Telecom Exploitation by Covert Surveillance Actors Summary

Generated by Codex with GPT-5

What happened

Techmeme surfaced this April 25, 2026 story through TechCrunch’s report, and the direct source used here is Citizen Lab’s Bad Connection: Uncovering Global Telecom Exploitation by Covert Surveillance Actors.

Citizen Lab says it uncovered two sophisticated telecom-surveillance campaigns that exploited the global signalling systems connecting mobile carriers, combining older SS7 pathways with Diameter traffic used in 4G and most 5G roaming. One campaign targeted a “VVIP” company executive across multiple 3G and 4G networks. Another used a specially formatted SMS carrying hidden SIM card commands intended to turn the victim’s device into a tracking beacon. The larger point is that both campaigns treated the mobile network itself as the surveillance platform.

What happened

Techmeme surfaced this April 23, 2026 story in its Techmeme item, and the original article is OpenAI’s Introducing GPT-5.5.

OpenAI is positioning GPT-5.5 as more than a routine model refresh. The company says the model is better at carrying work forward with less micromanagement: understanding messy instructions, planning steps, using tools, moving between apps, checking results, and finishing longer tasks instead of stalling halfway through them. In practical terms, OpenAI is aiming GPT-5.5 at coding, browser-based research, data analysis, documents, spreadsheets, computer use, and early-stage scientific work.

Techmeme 20260421 SpaceX Is Working with Cursor and Has an Option to Buy the Startup for 60B Summary

Generated by Codex with GPT-5

What happened

Techmeme surfaced this story on its April 22, 2026 page, and the original article is TechCrunch’s SpaceX is working with Cursor and has an option to buy the startup for $60B.

At the center of the story is a deal that is much bigger than a normal infrastructure partnership. TechCrunch reports that SpaceX told investors it is working with Cursor on a next-generation coding and knowledge-work AI effort, and that the agreement gives SpaceX a choice later this year: either pay Cursor $10 billion for the partnership or acquire the company for $60 billion. Even in a market that has become numb to giant AI numbers, that structure is startling. It treats the collaboration itself as enormously valuable while also creating a path to full vertical integration if the training work goes well enough.
