Higher Valuations, Fewer Deals: What Carta's Q3 2026 Data Means for Your Next Round

Carta published its State of Private Markets: Q3 2026 report on November 5, 2026. Its headline is easy to misread. The rounds that closed were priced higher and sold less of the company than in past years, but fewer rounds closed. This guide walks through the seed and Series A numbers, what they can and can't tell you, and questions to work through before your own round.

Scope: every figure below is from Carta's report unless stated otherwise: US companies on Carta, aggregated and anonymized customer data, snapshot as of November 1, 2026. Medians describe rounds that closed, not your round. Treat them as context, not a target.

What Carta reported

Companies on Carta raised $49.3B across 1,179 rounds in Q3 2026. Carta says the last two quarters together topped $100B, its strongest six months since Q4 2021 through Q1 2022. Yet total deal count fell 21% year over year. Carta also notes that Q3 cash was 157% above Q1 2023 while the round count was 8% lower, so the average round more than doubled in size.

Carta's own summary lists more capital, higher valuations, less dilution and shorter gaps between rounds, then adds the caveat that matters most: for many founders, the real question may be whether they can raise at all.

Seed and Series A: higher prices, fewer rounds

Pre-money valuation is the company's agreed value just before the new money goes in. Carta reports medians for primary rounds (the first equity round in a series).

Carta says Q3 had the lowest seed deal count since at least the start of 2023, and the same was true at Series A. It also expects the Q3 counts to rise as late rounds are logged. A median of closed rounds describes the companies that got through. It does not show how many companies tried and didn't, or what your own round will price at.

What founders kept: dilution, 2019 vs 2026

Dilution here means the share of the company that a round's new shares represent. Carta's chart shows median dilution falling at every stage.

Carta runs a hypothetical: a company raising every round from seed through Series D at the median rates compounds to about 66% total dilution at 2019 rates and about 53% at 2026 rates. You can check it by multiplying what is kept after each round: 0.782 × 0.758 × 0.797 × 0.834 × 0.859 ≈ 0.338 kept (about 66% diluted), versus 0.808 × 0.821 × 0.871 × 0.895 × 0.909 ≈ 0.470 kept (about 53%).

That is a chain of medians, not a forecast for any company. Real paths add option-pool top-ups, SAFE conversions, bridges and secondaries. The priced-round dilution guide explains how the pool and pre-money interact, and the priced-round demo lets you try synthetic numbers.

Terms to read, not just the price

• Down rounds (priced below the company's previous priced round): 12.8% of priced rounds in Q3 2026 on Carta's chart, which its text rounds to 13%, the lowest in four years. The peak was 23.4% in Q1 2024.
• Bridge rounds: Carta counts any round raised after the first round in a series as a bridge (for example, a second Series A raise). Series A was the one stage where bridges rose: 32% of Series A rounds in 2026 so far, up from 29% in 2025 and nine points above 2019. About one in four seed rounds this year was a bridge.
• Participating preferred (the investor gets its money back first, then also shares in what's left alongside common holders): more than 10% of Q3 2026 rounds, the highest rate in six years. Carta says it is now more than twice as common as cumulative dividends or a liquidation preference above 1x, though a large majority of rounds include none of the three.

How these terms work depends on the documents and the governing law. Read the full term sheet with counsel, not just the price.

Timing: how long between rounds

Carta's chart of median days between primary rounds (measured by the date of the later round) shows, for Q3 2026:

• Seed to Series A: 664 days (about 22 months), down from a peak of 869.
• Series A to Series B: 746 days, down from a peak of 1,045.
• Series B to Series C: 710 days, which Carta says is 42% shorter than a year earlier.

These gaps only count companies that did raise the next round. Companies still raising, or that never raised again, are not in them. A useful check is what your runway plan assumes about the gap, and what happens if it runs longer than the median.

What this data can't tell you

• Whole market: it covers US corporations on Carta raising equity in US dollars. Other data publishers report different medians. Outside the US, valuations, terms and law differ.
• Your odds: medians of closed rounds say nothing about rounds that never closed.
• Mix effects: AI startups took 44% of seed and Series A cash in 2026 so far (48% in 2025) and 57% at Series B and later. Hardware medians run far higher, at $27.2M pre-money for seed and $108.4M for Series A. Sector mix moves the overall median.
• Revisions: the data is a November 1 snapshot, and Carta says past figures change as transactions are logged. Even within the report, the text puts Q3 seed cash at $4.1B (up 21% year over year) while the seed chart shows $4.4B. We note the gap rather than pick one.

Questions to ask before your next round

1. For each benchmark I quote, do I know the source, date, period and measure (pre- or post-money, median or average)?
2. Is the valuation being discussed pre-money or post-money, and does the option-pool increase sit inside the pre-money?
3. What would my cap table look like if I need a bridge before the next priced round?
4. Beyond price, what do the terms say about liquidation preference, participation, dividends and pro rata rights?
5. How many months between rounds does my runway plan assume, and what is the plan if it takes longer?
6. Do my SAFEs or notes convert in this round, and at what effective price? (See the stacked SAFEs guide.)
