Medium gives employees Friday off to participate in national strike protesting ICE
Hustle culture may be the norm at tech companies in the AI era, but the work will stop tomorrow at publishing platform Medium. Medium CEO Tony Stubblebine is giving the company’s employees permission to take the day off to participate in tomorrow’s nationwide general strike protesting U.S. Immigration and Customs Enforcement, or ICE.
Activists behind the general strike are calling for “no work, no school, and no shopping” amid a push to defund ICE, which has escalated raids in U.S. cities, killing several people, including two U.S. citizens earlier this month in Minneapolis.
In a Slack message shared today with Medium staff, Stubblebine says all employees are free to participate in the strike however they see fit.
“Whether or not you want to fully take the day away from work, or do a partial work day, or orient your work towards something that feels aligned to the goals of the strike, that is up to you,” he wrote in a general announcements channel.
The exec clarified that Medium is not “in the business of dictating people’s politics,” so the choice to participate was an individual one, not a company mandate.
Of course, the publishing platform has an important role in helping people share news, opinions, insights, and analysis around politics, culture, and other topics. So that it can allow its employees to take the day off to protest, Stubblebine said Medium will coordinate with the necessary teams to ensure there’s a plan for “business continuity” on Friday.
Tech leaders, including Google DeepMind chief scientist Jeff Dean, have been outspoken in protest of ICE. Still, many large tech companies and executives have spent the last several weeks courting favor with the Trump administration. Some execs — including Apple CEO Tim Cook — were criticized for attending the screening of the Amazon MGM Studios-produced “Melania” documentary on the day federal border control agents shot and killed ICU nurse Alex Pretti in Minneapolis.
Many rank-and-file tech employees, meanwhile, have demanded that ICE and CBP (Customs and Border Protection) get out of U.S. cities, as evidenced by the open letter signed by more than 500 tech industry employees.
Stubblebine seems to share that opinion, writing that Medium has a responsibility to “make its stance clear,” especially “as many other tech orgs are donating to the Trump campaign.” He also said that Medium’s product exists to help “elevate truth and diverse voices,” not hateful content or racism.
His message also reiterated Medium’s support for DEI, the set of pro-diversity policies the Trump administration has attempted to dismantle through executive orders, the elimination of DEI positions in the federal workforce, curriculum removals, legal targeting, and more.
“Our business thrives when the country thrives, and so being out there representing is good for [our] mission,” Stubblebine said.

New York lawmakers propose a three-year pause on new data centers
New Yorker state lawmakers have introduced a bill that would impose a moratorium of at least three years on permits tied to the construction and operation of new data centers. While the bill’s prospects are uncertain, Wired reports that New York is at least the sixth state to consider pausing construction of new data centers.
As tech companies plan to spend ever-increasing amounts of money to build AI infrastructure, both Democrats and Republicans have expressed concerns about the impact those data centers might have on surrounding communities. Studies have also linked data centers to increased home electricity bills.
Critics include progressive Senator Bernie Sanders, who has called for a national moratorium, as well as conservative Florida Governor Ron De Santis, who said data centers will lead to “higher energy bills just so some chatbot can corrupt some 13 year old kid online.”
More than 230 environmental groups including Food & Water Watch, Friends of the Earth, and Greenpeace recently signed an open letter to Congress calling for a national moratorium on the construction of new data centers.
Eric Weltman of Food & Water Watch told Wired that the New York bill — sponsored by state senator Liz Krueger and assemblymember Anna Kelles, both Democrats — was “our idea.” Data center pauses have also been proposed by Democrats in Georgia, Vermont, and Virginia, while Republicans sponsored similar bills in Maryland and Oklahoma.
According to Politico, Krueger described her state as “completely unprepared” for the “massive data centers” that are “gunning for New York.”
“It’s time to hit the pause button, give ourselves some breathing room to adopt strong policies on data centers, and avoid getting caught in a bubble that will burst and leave New York utility customers footing a huge bill,” she said.

Last month, New York Governor Kathy Hochul announced a new initiative called Energize NY Development, which her office said would both modernize the way large energy users (i.e., data centers) would connect to the grid while also requiring them to “pay their fair share.”

NBA star Giannis Antetokounmpo joins Kalshi as an investor
Giannis Antetokounmpo of the Milwaukee Bucks announced Friday that he has joined prediction market Kalshi as a shareholder, making him the first NBA player to invest directly in the company.
“The internet is full of opinions. I decided it was time to make some of my own,” said the two-time NBA MVP in a social media post. “Today, I’m joining Kalshi as a shareholder. We all on Kalshi now.”
The announcement has not gone over well on social media. On Reddit, for example, one user described it as “literally a conflict of interest,” while another described Kalshi as “cancerous” and yet another wondered, “is this even allowed.”
According to The Athletic, the NBA’s recent collective bargaining agreement allows players to advertise and take stakes of up to 1% in sports betting companies, as long as they’re not promoting league-related wagers.
Kalshi said it will partner with Antetokounmpo on marketing and live events — and in accordance with the company’s “strict terms of service that ban insider trading and market manipulation,” he will not be allowed to trade on markets related to the NBA.

Benchmark raises $225M in special funds to double down on Cerebras
This week, AI chipmaker Cerebras Systems announced that it raised $1 billion in fresh capital at a valuation of $23 billion — a nearly threefold increase from the $8.1 billion valuation the Nvidia rival had reached just six months earlier.
While the round was led by Tiger Global, a huge part of the new capital came from one of the company’s earliest backers: Benchmark Capital. The prominent Silicon Valley firm invested at least $225 million in Cerebras’ latest round, according to a person familiar with the deal.
Benchmark first bet on 10-year-old Cerebras when it led the startup’s $27 million Series A in 2016. Since Benchmark deliberately keeps its funds under $450 million, the firm raised two separate vehicles, both called ‘Benchmark Infrastructure,’ according to regulatory filings. According to the person familiar with the deal, these vehicles were created specifically to fund the Cerebras investment.
Benchmark declined to comment.
What sets Cerebras apart is the sheer physical scale of its processors. The company’s Wafer Scale Engine, its flagship chip announced in 2024, measures approximately 8.5 inches on each side and packs 4 trillion transistors into a single piece of silicon. To put that in perspective, the chip is manufactured from nearly an entire 300-millimeter silicon wafer, the circular discs that serve as the foundation for all semiconductor production. Traditional chips are thumbnail-sized fragments cut from these wafers; Cerebras instead uses almost the whole circle.
This architecture delivers 900,000 specialized cores working in parallel, allowing the system to process AI calculations without shuffling data between multiple separate chips (a major bottleneck in conventional GPU clusters). The company says the design enables AI inference tasks to run more than 20 times faster than competing systems.
The funding comes as Cerebras, based in Sunnyvale, Calif., gains momentum in the AI infrastructure race. Last month, Cerebras signed a multi-year agreement worth more than $10 billion to provide 750 megawatts of computing power to OpenAI. The partnership, which extends through 2028, aims to help OpenAI deliver faster response times for complex AI queries. (OpenAI CEO Sam Altman is also an investor in Cerebras.)

Cerebras claims its systems, built with its proprietary chips designed for AI use, are faster than Nvidia’s chips.
The company’s path to going public has been complicated by its relationship with G42, a UAE-based AI firm that accounted for 87% of Cerebras’ revenue as of the first half of 2024. G42’s historical ties to Chinese technology companies triggered a national security review by the Committee on Foreign Investment in the United States, bumping back Cerebras’ initial IPO plans and even prompting the outfit to withdraw an earlier filing in early 2025. By late last year, G42 had been removed from Cerebras’ investor list, clearing the way for a fresh IPO attempt.
Cerebras is now preparing for a public debut in the second quarter of 2026, according to Reuters.
