The gaslighting here is astonishing. Acting President @ClaireShipman should speak for herself. As a @Columbia faculty member I do not share her values of authoritarian university governance and enforcement of ideological conformity, all to advance a racist Trump admin agenda.

new paper w/ @malleshpai @Weiye_Xi @Qiaoqiao2001 a principled approach to quantifying uncertainty in prediction markets 👇

@malleshpai very outerboro nyc!

Who amongst us hasn't asked I wish I could get my cigars and law enforcement supplies under one roof...

@malleshpai congrats!

Under stress, derivatives protocols have to make hard decisions in real time: → How options decay → How leverage is reduced → How ADL is triggered → How losses are allocated → How solvency is restored Full recap of the Perpetual Futures & Derivatives track at D²: substack.com/home/post/p-20…

I am sad to hear of the passing of Dimitri Bertsekas. This one hurts. Dimitri had a big effect on my career, from inspiring research topics to writing one of my tenure letters. A long thread on memories of Bertsekas and some of his works that influenced me the most.

Dimitri was both a giant and a kind man. Sad day today.

D² brings together research on DeFi protocol design, incentives, and market behavior Across two days, the program spans: → DeFi Microstructure → Perpetual Futures & Derivatives → Mechanism Design → Prediction Markets → AMMs Learn more: designingdefi.xyz

The leadership at @Columbia seek to discipline a student for ... criticizing the trustees. So much for academic freedom and open discourse. The fish rots from the head down.

Sharif is the #1 university in Iran. Over the last 25 years, it has been in the top 3 destinations of top Olympiad medalists.

@HalSinger @ZohranKMamdani @TheEconomist moreover the apartments like Ken Griffin's are extremely advantageously taxed currently x.com/ciamac/status/…

Hadn’t been following the @ZohranKMamdani second home (“pied-à-terre”) tax closely until this @TheEconomist article reviewed it. The conditions under which the tax would apply are smartly written to target only the uber rich who own a second home in NYC (1) worth more than $5M (2) whose owners are not tax residents and (3) do not rent them out. Yet the neoliberal rag maintains the tax “could do real harm,” citing a billionaire (and non-economist) who speculates it could cost the city jobs. Get a fricking grip. There is no nexus between the tax and job creation. On the benefit side, the tax would “nudge some absentee owners to sell to New Yorkers who might make greater use of them,” as the story admits. And the tax would raise $500M per year in revenues. Seems like a no brainer and easily passes a cost-benefit test. Go get em!

Data from here: taxequitynow.nyc/maps_charts/is…

Ken Griffin pays only 0.22% of the market value of his $240M condo in property tax, whereas condos in the lowest 10th percentile (<$350K) pay almost 1.4%.

How do onchain markets actually work? D²’s DeFi Microstructure track covers the mechanics behind latency, fees, staking, and block building: → Latency races on blockchains: Brian Zhu → Fee mechanisms under execution uncertainty: Sarisht Wadhwa → Liquid staking and policy limits: Fayçal Drissi → EVM workloads in the wild: Jason Milionis → Ethereum block-building resilience: Sen Yang

Sharif University of Technology (founded as Arya Mehr University in 1966) is an icon of modernization and progress in Iran. Its alumni include the first woman to win the Field Medal in Mathematics, Maryam Mirzakhani. It has been a national symbol of achievement, gaining international recognition for the quality of its graduates, large number who have been admitted into the very best engineering programs in the West. The aim of this kind of wonton destruction could only be the nation of Iran itself.

@TheSpeculator0 this is the way kalshi charges also. this is because the fee per contract should be symmetric between p and 1-p, there is no difference between buying a YES at price p and selling a NO at price 1-p.

Polymarket enabled fees today for more markets and it's yet again another complete shitshow: previously it was already live on crypto markets with the following formula: fee per contract = p × feeRate × (p × (1 - p))^exponent This means that the fee is a parabola around 50c in terms of how much you pay as % of your premium. somewhat reasonable. Today, they, without telling anyone, removed the first p term in the formula, so it just becomes: fee per contract = feeRate × (p × (1 - p))^exponent Now fee in dollars is a parabola, but fee as a % of premium has an extreme inverse relationship to price. If you spend 100 dollars on a contract with a 0.1c price, you will pay 30 dollars in fees in e.g. the economics category. Insane tax on small bets and this is going to reduce turnover a lot of people who want to get out of near 1/0 positions (the same is true of markets trading at e.g. 99.9 from an EV perspective)

Oh man, who knows where this will lead, but at the least we may get to read some VERY interesting emails from and to Columbia's oligarchic trustees and admins: Court Finds Columbia May Have Acted as Government’s Instrument to Suppress Palestinian Advocacy cair-ny.org/news/3/19/26-b…

🚨 NEW: Over the past year, Columbia University has played a direct role in the arrests and targeting of its international students by federal immigration agents, in violation of the university's own stated policies and protocols. What began last March has continued since — Mahmoud Khalil, Mohsen Mahdawi, Ranjani Srinivasan, Yunseo Chung, Elmina Aghayeva...
