Funding History and Live Funding Data on Polymarket Perps: What's Available and How to Read It
Funding doesn’t have to be a surprise billed hourly. The protocol publishes the pressure before settlement — a rolling premium sample, its implied rate, and complete funding history per market. Traders who read these feeds open positions knowing what carry costs (or pays); traders who don’t discover it on their PnL. Here’s what’s available and the two reads that matter.
Can I see funding data before settlement on Polymarket Perps?
Yes — three feeds. The rolling premium sample: the 5-second
book-walk sample (1,000 quote-asset notional per side) published
continuously, with its implied 8-hour rate — this is live pressure, the
“funding now” number. Funding history: full per-window history via
the public endpoint (GET /v1/info/funding) — what each past settlement
actually charged. Your own funding ledger: your fills and funding
payments are queryable on your account. The endpoints are covered in
the API guide; the formula that
turns samples into settlements is in
funding mechanics.
The two reads that matter
Read 1 — trend. Is the implied rate growing, stable, or decaying? Growing premium = crowding increasing — the crowd is paying up for the same view you’re about to take. A position opened into rising premium locks in a worsening carry; a position opened into decaying premium may catch the reversal. For carry strategies, trend is the signal itself — see the playbook.
Read 2 — sign. At the current rate, are you paying or receiving? Longs pay when the perp trades above the underlying; shorts pay below. The thin side collects — and being paid to hold your view is a real edge component (the cost math per leverage is in the forecaster guide). A “wrong-side” position isn’t forbidden — it’s a cost you either accept with eyes open or structure around (entry timing between windows, size discipline — see the cost levers).
Building the pre-entry habit
Before any leveraged position: pull the implied rate, eyeball its trend over the last few hours, compute your drag at your leverage and horizon, and only then size. The free funding-forecaster CLI automates exactly this from the live book — run it before entry, not after. For held positions, re-check at least daily: premium signs flip when the crowd rotates, and yesterday’s received-funding position can become tomorrow’s paying one (see why signs flip).
What funding history tells you about a market
Per-market history is a positioning diary: sustained saturation at the +4% cap marks news-cycle euphoria; sign flips mark crowd rotations; long flat stretches near zero mark healthy two-sided books. Backtesting carry strategies requires exactly this history — the backtesting guide uses it for cost models. And for the deepest question — why a market’s premium persists — correlate funding history with event proximity: event weeks exhibit the fattest, most persistent premiums.
FAQ
Where can I see funding rates on Polymarket Perps?
Three feeds: the rolling 5-second premium sample with implied rate
(public market data), full funding history via GET /v1/info/funding,
and your account’s funding ledger — see
the API guide.
How do I check funding before opening a position? Read the implied rate (live), its trend (last few hours), and compute your drag at your leverage and horizon — the free funding forecaster does it from the live book in one command.
What does it mean when funding hits the 4% cap? Maximum crowding: the perp’s premium saturated the clamp — news-cycle euphoria in the books. Expect the cap during events; positions paying at cap burn margin fast (see the liquidation interaction).
Can I earn funding instead of paying it? Yes — hold the thin side: shorts on positive-premium markets and longs on negative-premium ones receive funding hourly. Carry as an edge is a real strategy class — see the leverage playbook.
Why did funding flip against my position overnight? The crowd rotated — premium sign follows positioning, not your thesis. Re-read the implied rate daily on held positions and re-project your carry (see the two reads).
