Recurring Themes

Novel Ideas

### Crypto - Saylor selling is bullish. Strategy's "cover the preferreds" bucket is limitless and self-authorized, making the watched sale-authorization number meaningless; a predictable, orderly wind-down removes blow-up risk. (Bankless) -> DATCOs - Polymarket's 5-minute BTC contracts are manipulable via oracle timing. ~821 traders fired large Binance buys in the final ten seconds before settlement, extracting $8.2M while retail absorbed 93% of losses; and the effect nearly vanished in 15-minute contracts. (Unchained) -> Native DeFi - Some DeFi pools are engineered to defeat pre-trade simulation. Enso found live pools that pass a wallet's simulated quote at an attractive price, then execute at a worse rate; weaponizing the exact safety check meant to protect traders. (Unchained) -> Native DeFi

### Macro - The Fed's constitutional soft spot is bank regulation, not monetary policy. The Court shielded monetary policy but not the regulatory functions legally inseparable from it, so independence could unravel at that seam. (Odd Lots) -> Fed independence - Levered-ETF systemic risk is notional, not AUM. When retail is the marginal buyer, mechanical negative-gamma rebalancing sets price for weeks; until a 3-5% drop cascades into forced de-risking. (Odd Lots) -> BTC-Nasdaq correlation

### Business - Chip-backed lending is fragmenting Nvidia's moat. General Compute's $400M loan collateralized by SambaNova SN50 inference chips signals capital markets pricing non-Nvidia silicon as collateral; a financing primitive that rewards the inference/open-model stack. (TechCrunch) -> AI Infrastructure CapEx - "AI-ify stale digital natives" is the next mega-deal wave. The ~$53B PayPal bid and Ryan Cohen's eBay bid mark the start of buying mature, founder-departed businesses to revive them with AI-native operators and cheap capital. (All-In) -> AI services moat

### AI - AI scientific discovery will be radically uneven across fields. Discovery is a tree search whose payoff depends on a domain's "branching fraction"; theory-constrained fields like quantum gravity benefit most from massive LLM parallelism, experiment-bound fields least; expect AI as a superhuman explainer, not a producer of inscrutable proofs.
