Info Finance
Using financial market mechanisms to elicit, aggregate, and trade on informational signals about future events. Coined by Vitalik Buterin in Nov 2024 · prediction markets are one application within a broader ecosystem that also touches governance, scientific research, journalism, and social media.
Key insights
- Vitalik's framing: PMs represent one app within a broader info-finance ecosystem. Mechanisms can improve governance, scientific research, journalism, and social media via information-pricing that goes beyond simple betting (Buterin, Nov 2024).
- Robin Hanson's regulatory argument: PMs deserve the same regulatory treatment as journalism and academia. Six common harms are shared across all information systems (insider trading, manipulation, etc.) · markets should be approved by default and restricted only on clear evidence of specific harm (Hanson, response to CFTC call for comments).
- ARK sizes PM opportunity "up to ~$5 trillion" medium-term, arguing PMs "could become a foundational layer of financial services, impacting markets well beyond sports." Frames PMs as truth-discovery infrastructure backed by capital rather than opinion, against a backdrop of historically low trust in journalism and government (only 22% of Americans trust the federal government). Sports adoption is the on-ramp, not the destination (Grous, Prasanna, Hadi · ARK).
- Equity analyst workflow using PM probabilities: translate Polymarket's 51% tariff refund probability into 35% effective probability for Logitech's margin impact; 29.5% FDA approval into $5.4B EV uplift for Eli Lilly. Raw probabilities must be adjusted for contract wording mismatches and economic relevance (Alistair Smallwood).
- 2025 = $63.5B volume; 2026 run rate $200B+. Sports drive current revenue (83% of Kalshi) but valuations price in info-infrastructure future that hasn't arrived. Distribution platforms (Robinhood, Coinbase) capture most value as they vertically integrate into exchange infrastructure (Kaviish).
- ~13,500 Polymarket contracts: >80% volume in sports/crypto/elections; accuracy on "useful" markets hasn't improved since early 2025. AI chatbots may supersede PMs as the primary forecasting interface (Dan Schwarz).
- Probability layers: attention markets (content virality), credibility markets (trust as score), demand markets (consumer intent before production) · probability signals embedded invisibly into every decision surface on the internet (Aggie).
- Prediction markets are at an inflection point. History from 1419 Vatican papal elections → Iowa Electronic Markets → Polymarket era. Insider trading scandals (Musk tweets, French elections), moral hazard (assassination markets), wave of new entrants (Robinhood, DraftKings, Crypto.com, FanDuel) signal mainstream adoption (Eniola).
- Agentic bazaar: PMs are the natural marketplace for sovereign AI agents to trade their core commodity · information. Agents monetize alpha through positions; market creators earn fees from surfacing unanswered questions; reproducible computation enables incorruptible AI judges. Alternative to centralized AI lab alignment · market incentives align agents through financial participation (Ben Fielding).
- Retail financial speculation has permanently shifted from investment to entertainment, driven by smartphones and zero-commission. 0DTE options = 59% of options volume in 2025. Event markets expanding to cover everything; insider trading cases proliferate (Hariharan, Dopamine Markets annual letter).
- Perpetual attention markets: Trendle treats social engagement as a tradable index. Two-layer architecture (attention index + market layer). Anti-gaming: normalization, deseasonalization, quantile clipping. Funding rates penalize crowded positions. "Attention is the only scarce resource in the digital age" (michaellwy).
- TikTok moment for PMs: shift from edge-seeking tools for professionals to identity-signaling social platforms. TikTok-like feed where bets become public expressions of belief, removing friction of intent (michaellwy).
- Financialisation of social networks: PMs as predecessors to financialized social. Polymarket briefly hit #1 in app stores · linking user views to financial stakes creates engagement through capital formation rather than pure attention capture. Stress-test for Web3 social primitives (Joel John).
- Vitalik on Venezuela: at the moment people put "over a hundred thousand dollars on the line, betting that there is a 23% chance that this election would be the one where Maduro would actually get struck down," it served as a news-detection signal · independent of whether the bet resolved correctly. The PM = newspaper for non-bettors, betting site for bettors. "You can be more informed by reading the news and the charts, than by reading either one alone."
- Vitalik on the AI unlock: "subsidies are required" on many low-volume markets because there aren't enough naive traders for sophisticated traders to take profit from. AI agents change the math: "we could potentially get reasonably high-quality info elicited even on markets with $10 of volume."
- Vitalik on Hanson's "distilled human judgement": every time you need a decision, set up a PM on what a trusted-but-slow mechanism would say. Run the costly mechanism 0.01% of the time (random sampling or for high-volume markets) and compensate participants based on that. "Credibly neutral fast and cheap distilled version of the original highly trustworthy but highly costly mechanism."
- Vitalik on personal tokens (friend.tech, Bitclout): "proto info-finance" with the wrong economic design · reflexivity and bubble dynamics dominate. Hanson's "prestige futures" is the proposed clean version.
- Hanson "On Prediction Market Regulation" · six axes of info-institution harm: (A) reveal info better kept secret, (B) break promised secrecy, (C) waste time/money, (D) misleading contributions for favorable treatment, (E) change the world to get favorable treatment, (F) reward participants unequally. PMs share these with journalism, gossip, academia. Hanson's empirical claim: "at public firms announcements, half of the price change happens beforehand, and half of that is from insider trading" · i.e., insider rules in equity markets don't actually prevent leakage, so we shouldn't expect PM rules to either. Speculative markets are "far more resistant to manipulation than other info institutions" because "when traders expect more efforts to manipulate a price, they respond so that prices on average become MORE accurate." Free-speech argument: trades should be treated like protests · "as there are things you can say with trades you can't say via words."
- Hariharan "Dopamine Markets": 2024 election attracted >$4B between Polymarket and Kalshi. Polymarket acquired QCEX for a CFTC license. Polymarket raised $2B at $9B from ICE; Kalshi raised $1B at $11B from Paradigm. Sports betting in 2025 = ~$165B wagered, 95% of bettors lose. FanDuel/DraftKings stocks fell ~30%. Insider trading cases proliferating: Taylor Swift engagement, Google search ranking, Nobel Peace Prize, 100+ UFC fights, NBA (Terry Rozier, Chauncey Billups, Jontay Porter). 43% of Americans say sports betting is bad for society (Pew, July 2025), up 9pp in 3 years. Investment-as-entertainment dynamic confirmed: 0DTE options = 59% of options volume in 2025; Hyperliquid breakout; Coinbase pushes "perpification of everything."
- Joel John "Financialisation of Social Networks": blockchains move capital at the speed of data; meme markets and Polymarket are predecessors to a new social-network primitive where "the next big exchange will be a social network. The next big social network could be an exchange." Three primitives needed: asset issuance, context+trading, coordination. Receipts (fitness data → on-chain credentials) and Muzify (Spotify streams → artist-fan graph) are early examples.
- michaellwy "Perpetual Attention Markets": Trendle aggregates X/Reddit/YouTube signals into a per-topic Engagement Index normalized to 0-1, with deseasonalization (sports teams spike on game day so that's filtered out). Up to 5x leverage. There's no spot oracle to anchor to, so funding rates serve as a "crowding tax" rewarding the minority side · "Trendle makes timing the end of hype a coherent strategy." Future expansion to Google Search, TikTok, news media.

Where it matters
"Info finance" is the framing every serious PM team has adopted as the long-form pitch · it reframes "PMs as gambling" into "PMs as one app on top of a probability-pricing protocol stack." For builders, this is the narrative that lets you talk to VCs and regulators without sounding niche. For Dekant specifically, info finance is the home for the distribution-market thesis: a binary contract is just the cheapest possible probability surface; the real prize is pricing every shape of belief, not just every yes/no question.
