Synth (SN50) LLM for Traders Launches Across Polymarket, Hyperliquid, Limitless, and Deribit
Synth, the Bittensor Subnet 50 building decentralized predictive intelligence for financial markets, has launched Synth (SN50) LLM for Traders. The new tool delivers an LLM-native interface that converts live Monte Carlo forecasts into custom statistics, charts, and example trades.
Initial coverage spans Polymarket, Hyperliquid, Limitless, and Deribit, with additional venues planned. According to the team, this is the first conversational interface that translates probabilistic price-path forecasts directly into trader-ready outputs.
What Synth (SN50) LLM for Traders Actually Does
Most forecasting tools return a single price target. Synth instead generates 1,000 simulated price paths for each asset over short and long horizons. Together, those paths capture the full probability distribution of future moves. Until now, accessing that data meant working with the Synth API, dashboards, or raw JSON.
The new Synth (SN50) LLM for Traders layer sits on top of those forecasts. Traders can ask natural-language questions and receive custom outputs. Examples include probability statistics tailored to a specific market, charts showing the simulated path cloud, and example trades calibrated against current pricing on the target venue.
For prediction market users, this changes the workflow significantly. Instead of stopping at "Synth thinks BTC has a 62% chance of closing above X," the output becomes a fully framed position against the live Polymarket order book in seconds.
The Technology: 200+ Models Competing on CRPS
Synth runs on Bittensor Subnet 50, where over 200 machine learning models compete continuously to produce the most accurate probabilistic forecasts. Validators score miners using the Continuous Ranked Probability Score (CRPS). This industry-standard metric measures both calibration and sharpness against actual market outcomes.
The subnet maintains two leaderboards. High-frequency forecasts cover 1-hour horizons with 1-minute increments and refresh every 12 minutes. Daily forecasts cover 24-hour horizons with 5-minute increments and refresh every hour. Emissions split evenly between the two streams, at 50% each.
Forecast coverage currently spans Bitcoin, Ethereum, Solana, and gold (XAU). The Synth API additionally supports equities and commodities. Recent performance from the top-ranked miners feeds the ensemble forecasts that now power the LLM interface.
Proof of Concept on Polymarket
Synth has been running a public account, @SynthDataDotCo, on Polymarket since October 3, 2025. The account trades the BTC Hourly Up/Down market. Synth derives its implied probability from the share of forecast paths ending higher, then compares that probability against Polymarket's posted odds. When the gap favors the model, it takes the side with positive expected value.
Starting with $3,000, the bankroll reportedly grew 10x within seven weeks (around $30,000) and 20x within six more days (around $60,000), according to figures the team shared on its X account in November 2025. Bankless independently profiled the experiment in December 2025, citing a balance of approximately $73,000 at the time of publication.
The new LLM interface formalizes that workflow for outside traders. Custom code and direct API queries are no longer the price of entry.
Why the Timing Matters
The launch lands during a structural shift in prediction markets. Monthly volume across Polymarket and Kalshi reached close to $24 billion in April 2026, according to Bernstein data cited by DL News. Hyperliquid activated its HIP-4 outcome markets on mainnet on May 2, 2026. The upgrade pulled binary contracts into the same margin account that already runs perpetual futures and spot positions.
That move turned the largest decentralized derivatives venue into a direct competitor for prediction market flow. According to Hyperion DeFi CEO Hyunsu Jung, Hyperliquid's first canonical market, a daily BTC binary, did roughly three times the volume of equivalent contracts on Polymarket and Kalshi combined during its first session.
For sophisticated traders, the result is a fragmented landscape. Each venue has distinct pricing quirks, fee structures, and liquidity profiles. A tool that surfaces probabilistic mispricing across all of them in one interface fits the moment.
What Comes Next
The team says additional venues will follow the initial four. Synth API access already supports agentic payments via x402, a Bittensor-first integration the project rolled out in October 2025. That integration lets AI agents purchase predictive intelligence on demand for on-chain actions.
For the broader Bittensor ecosystem, the launch adds another data point that subnet-driven AI can produce financial products competing with centralized alternatives on accuracy. Whether the Synth (SN50) LLM for Traders interface scales to the combined volume of Polymarket, Hyperliquid, Limitless, and Deribit will become clear in the coming weeks.
