LEGAL BATTLES AND THE REAL FIGHT FOR PREDICTION MARKETS ⚔️
Record-breaking market data, a class-action lawsuit shaking the industry, Forbes anointing Shayne Coplan as a generational founder, and much more!
🧩 HEADLINE STORY — THE KALSHI LAWSUIT
A class-action lawsuit filed on Nov 27 in the U.S. Southern District of New York alleges that Kalshi misled users by operating like a sportsbook instead of a true P2P exchange. The suit also claims the platform targeted underage users and advertised itself as being legal in all 50 states.

The filings triggered a wave of knee-jerk reactions on X:
“If a project calls itself a prediction market but acts like a sportsbook, that’s a problem for the whole industry.”
“They literally talk about legal trading and make fake claims about being legal in 50 states.”
But remember — these are allegations, not facts.
Nothing is proven.
How Kalshi responded
Co-founder Luana Lopes came out swinging in a rare public post:
Calling the lawsuit a “pure smear campaign.”
Claiming competing platforms are paying accounts to amplify false narratives.
Reiterating that Kalshi is a regulated exchange, not a house.
Confirming that market makers — including Kalshi Trading — receive no special access, aren’t profitable, and only exist to bootstrap liquidity.
And she ended with a message the whole space needs to hear:
“It’s disappointing to see other prediction markets contributing to destructive infighting. This hurts everyone.”
That’s the line.
Instead of PM-vs-PM drama, the real fight is prediction markets vs. the entrenched legacy industry.
If platforms burn energy attacking each other, the ones cheering are the old sportsbooks and the traditional intermediaries.
📌 Our takeaway: the space needs coordination, not chaos. A cross-platform lobbying or policy group seems inevitable.
💸 BUILDERS & ECOSYSTEMS — ROMAN FROM BRAVADO TRADE
Our guest today: Roman from Bravado, building what may become the first true cross-chain, cross-platform aggregator for prediction markets.
What Bravado wants to solve:
Most terminals today simply sit on top of Polymarket endpoints.
They cap out at features like the top 20 holders, because that’s all the API exposes.
Users still need multiple wallets, KYC flows, multiple bridges.
Bravado’s angle?
A single wallet → access to Polymarket + Kalshi
No extra signups.
No silos.
They’re doing this via a partnership with Kalshi’s order book infrastructure, allowing users to place trades on Kalshi from a Web3 wallet without touching Kalshi’s traditional onboarding.
A few highlights from the conversation:
MVP launches before Christmas or early January.
Polymarket support comes first; Kalshi integration lands in January.
Auto-bridging so a user can trade from ETH → Solana without thinking.
Small spread-based fee model, no token planned.
Fully bootstrapped team of 6 with backgrounds at Coinbase, Arbitrum, Boston College.
This is the kind of infrastructure that reshapes UX expectations and pushes prediction markets forward.
Whitelist is open. Check it out here.
📊 DATA OF THE WEEK — RECORDS EVERYWHERE
Even with the drama, the numbers don’t lie: prediction markets are exploding.
Kalshi: new all-time highs
From @kalshidata:
~17M transactions in November — already topping October by ~740k with days left to spare.
November on track to add 2x more transactions than September.
Pure exponential.

Myriad: crypto-native flow goes vertical
@Mausefalle25 flagged this:
Nearly $70M USDC in total November volume.
Mostly driven by Pengu-ecosystem crypto markets, where sentiment trading is red-hot.
Myriad has now crossed 2M cumulative transactions and $150M notional volume.

This seems to be proof that prediction markets are fracturing into verticals so far:
Sports → Kalshi
Elections and politics → Polymarket
Crypto sentiment → Myriad
💅 CULTURE CORNER — FORBES CROWNS SHAYNE
Shayne Coplan, founder of Polymarket, made Forbes with a deep dive into the deal that turned him into one of the youngest billionaires.
The narrative:
Prediction markets are going mainstream.
Polymarket is now culture, not just finance.
The Intercontinental Exchange investment (25% stake) is seen as a signal that “this isn’t fringe anymore.”
Whether you love the piece or roll your eyes at the phrasing, the article did its job:
It pulled an entirely new audience into the PM conversation.
📣 TRADER ALPHA — X IS FULL OF IT THIS WEEK
Greek Gambler shared a curated list of real traders on X who openly post their reasoning, strategy, and results. A few standouts:
Sipka — $150k profit, shares positions often.
Moses — $100k profit starting from $1.
Crypto Monday — strong track record around MrBeast markets.
GODRAMA — League of Legends angle.
PARZIVAL PM — new but already respected.
A trend we noticed this week:
People aren’t just posting trades — they’re posting clusters of on-chain behavior, especially around the Lightyear airdrop FDV markets. Some wallets clearly came in heavy with size and timing that looks… informed.
Not calling anything — just noting what the chain shows.
🧠 LESSONS & LEARNINGS — THE MINECRAFT EXAMPLE
@0xCryptoSam dropped a perfect breakdown of why prediction markets make you a better trader.
His point:
You can test mental models in places where your intuition is weak — without drowning in crypto’s usual noise.
He used the 2024 highest box office market as an example:
Minecraft at $0.15
Wicked 2 at $0.55
Zootopia 2 at $0.30
Minecraft had already locked ~$520M.
Wicked 2 had a late release and weaker cultural pull.
Zootopia 2 would split demand.
Even with only 40–60% confidence, the risk/reward was obvious.
That’s the real superpower of prediction markets:
They force you to put numbers on your beliefs, size your position, and let the math do the work.
🔮 CLOSING THOUGHTS
Today’s newsletter captured the entire arc of the industry:
Explosive growth, serious builders, cultural validation — and the legal friction that always comes when a frontier sector gets big enough to matter.
Prediction markets aren’t fringe anymore.
They’re becoming infrastructure.
And the real fight isn’t Polymarket vs. Kalshi vs. Myriad.
It’s prediction markets vs. the old guard.
Let’s keep pushing the space forward.
