Sui (SUI) climbed about 28.3% over the past 24 hours and now trades near $1.05, as of September 21, 2026, 13:19 UTC, per data from CoinGecko. Sui ranks 30th among the top 100 coins the detector tracks by market capitalization, and its network runs on the Move programming language with an object-centric data model. The token is up about 43.3% for the week, with most of that climb concentrated in the last few days rather than spread evenly across seven. Volume tells its own story. Roughly $2.02 billion changed hands in 24 hours against a $4.30 billion market cap, a turnover close to 46.9%. Sui was far from the only coin moving today. Fourteen other top-100 coins also crossed the 10% bar in the same window, Render topping that list at about 18.7% and Bittensor close behind at about 13.6%, while Bitcoin barely moved by comparison, up only about 5.7%. Nothing in the data checked for this page points to a specific reason for the jump.
The Short Version
SUI climbed about 28.3% in a day, to roughly $1.05.
The weekly gain sits at 43.3%, and most of it landed in the final few days rather than building evenly.
Volume hit roughly $2.02 billion against a $4.30 billion market cap, a turnover close to 46.9%.
Sui was not alone. Fourteen other top-100 coins cleared 10% too, led by Render and Bittensor, while Bitcoin rose only about 5.7%.
CoinGecko's 90-day chart shows today's price as a new high, after two choppy months mostly stuck between $0.64 and $0.85.
SUI pays its own network fee in its own token, so what that fee costs in dollars shifts along with the SUI price.
What's Behind the Move
Today breaks a pattern that had held for close to two months. CoinGecko's 90-day price history shows SUI stuck between about $0.64 and $0.85 from late July through mid-September, bottoming at $0.644 on August 18, 2026 and repeatedly drifting back into that same band afterward. Nothing forced its way out until today. The roughly 28.3% move pushed the price straight through the top of that range to about $1.05, a level CoinGecko's chart marks as a new 90-day high on the day this page went up.
The data checked for this page does not point to a specific cause. What it does show is scale. Fourteen other top-100 coins crossed the same 10% line in the same 24-hour stretch. The two nearest Sui in size of move, Render and Bittensor, both trade in the AI-compute corner of the market rather than anywhere near Sui's own ecosystem. Bitcoin barely budged by comparison, up only about 5.7%. A wide field of smaller and mid-sized coins moving together while Bitcoin sits mostly still reads more like a sector-wide risk appetite shift than a single Sui headline.
How Big Is a 28.3% Day for Sui, a Top-30 Coin?
Sui's market cap of roughly $4.30 billion puts it 30th among the top 100 coins the detector tracks, squarely in the middle of that group rather than near either edge. A large-cap name like Bitcoin or Ethereum moving 28.3% in a day would be extraordinary. A coin Sui's size clearing double digits is not shocking by itself, since mid-sized tokens carry more volatility than the biggest names. What sets today apart is not the percentage alone. It is the volume underneath it. Sui traded roughly $2.02 billion over 24 hours against that $4.30 billion market cap, a turnover near 46.9%. Few top-30 coins see close to half their market cap change hands in a single session. A ratio that high generally points to a broad set of orders moving the price rather than one or two large trades working through a quiet order book.
What a Jumping SUI Price Means for Your Wallet
Sui runs its own layer-1 network rather than settling on top of another chain, and a coin that pays its own way charges its network fee in its own token. The fee itself, priced in SUI, has not changed today. Its dollar value has, since SUI itself jumped about 28% since yesterday. At PipeFlare, we price our converters off the live rate rather than a cached number from this morning, and that gap matters more on a day like this one. Anyone who wants to know what a SUI balance is worth right now, or what a transfer will actually cost in dollar terms, can check our crypto converter for the current rate rather than guessing from yesterday's price. Readers newer to how balances move between wallets day to day can start with our crypto wallet guide, and our DeFi guide covers the kind of applications that run on networks like Sui.
How Sui's Price Moved Over the Past Two Months
The two months before today looked more like a holding pattern than a climb. Sixty days before publication, CoinGecko's chart puts SUI near $0.76. That slid to about $0.67 within a couple of weeks, and the slide continued until the token bottomed at $0.644 on August 18, 2026, its lowest print of the 90-day window. A bounce followed almost immediately, lifting the price to roughly $0.83 within days, but the recovery did not hold. SUI drifted back down near $0.72 by the end of August, climbed again to about $0.84 in the first week of September, then fell once more. Seven days before this page went up, the token was back at $0.72, a level it had already revisited twice that month. Calling that stretch a trend understates how often the price reversed. From that last dip, SUI held in the $0.80-to-$0.85 pocket for a few sessions before today's 28.3% surge blew through the top of the entire two-month band, landing at about $1.05, a fresh high for the period on CoinGecko's own chart.
Is Today's Jump a Breakout or a Reversal?
Today's move reads as a breakout. It does not look like a reversal of Sui's longer decline. Sui's two-year chart still carries a lot of distance the token has not closed. Its all-time high (ATH), $5.35, was set on January 4, 2025, and even today's gain leaves SUI about 80.3% under that mark. On the other end, the all-time low (ATL) of $0.364846 goes back to October 19, 2023, roughly a third of today's price. Both bookends sit far away, which means today is not a retest of anything from Sui's longer history. It is a shorter-term story. Measured against just the last 90 days, SUI closed out a range it had failed to escape since late June, roughly $0.64 to $0.85, and printed a new high above it. Breaking a multi-week ceiling on heavy volume usually carries more weight than the same break on a quiet session. One day of trading still is not proof by itself that the new level holds.
Is Sui's Trading Volume Confirming Broad Buying Interest?
The volume behind today's move looks like broad buying. It does not look like one large order pushing the price alone. A crowded trade shows up in the size column, and $2.02 billion in 24-hour turnover against a $4.30 billion market cap is a lot of size, close to 46.9% of the entire token changing hands in one day. Few top-30 coins see anywhere near that share move in a single session, so this stands out even before accounting for the price move itself. Numbers this size usually mean many independent buyers and sellers were active, rather than one large wallet moving a thin book. None of that guarantees the price stays here. A single seller unloading into a rising market can also generate heavy volume, with a wide set of buyers simply absorbing the supply, and the turnover figure alone cannot tell those two scenarios apart. What it does rule out is a quiet, thinly traded spike, the kind that sometimes explains a smaller coin's sudden jump.
What Would Change This Read
A real catalyst, if one turns up, would change how this jump should be read. It could be a listing announcement, new activity from Sui's developer or ecosystem side, or simply a sector of the market rallying together and pulling Sui along with it. The sector explanation fits best today. Render and Bittensor, the two other coins closest in size to Sui's move, both sit in the AI-compute corner of the market rather than anywhere near Sui's own ecosystem. Fourteen coins total cleared the same 10% bar in the same 24 hours, a spread that argues against one company-specific headline. None of this counts as a confirmed cause. It is a pattern visible in the data, without a named source behind it. Two things over the next few days would test whether today's move sticks. A SUI price that gives back most of this gain would support the choppy-range reading instead of a genuine breakout. Volume that stays elevated, rather than fading back toward its normal level, would support the opposite.
How to Check Sui's Live Price and Confirm These Numbers
Every number on this page describes a single moment, September 21, 2026 at 13:19 UTC, and crypto prices do not sit still. Sui's live price on CoinGecko is the quickest way to see how far the token has moved since this page went up, and that same page carries current volume and market cap for a side-by-side check against the figures above. For the project itself rather than the price, Sui's own site covers its Move-based programming model and current network activity, useful for anyone asking whether anything about the underlying project changed alongside the price. Anyone sending or holding SUI who wants the actual dollar value right now, rather than the number printed here, can run it through PipeFlare's crypto converter, which prices off the live rate.
Bottom Line
Sui jumped about 28.3% today to roughly $1.05, breaking out of the roughly $0.64-to-$0.85 range it had traded inside since at least late June and setting a new 90-day high in the process. Most of the accompanying 43.3% weekly gain landed in the final week rather than building steadily across all seven days. The move was not a solo act. Fourteen other top-100 coins cleared the same 10% bar in the same 24 hours, led by Render and Bittensor, while Bitcoin moved only about 5.7%, a spread that points toward a broad altcoin rally more than a Sui-specific headline. Roughly 46.9% of Sui's $4.30 billion market cap changed hands in the past 24 hours, a turnover figure high enough to suggest wide participation rather than a few large trades. Even with today's gain, SUI remains about 80.3% under its January 2025 peak of $5.35. Nothing in the data checked for this page confirms a specific cause, and one day of trading does not settle whether the breakout holds. Checking the live price before acting on it, whether that means deciding what the move changes or just pricing out what a SUI transfer costs today, is the more useful step than reading too much into a single session.
Common Questions
Why is Sui (SUI) up today?
Sui jumped about 28.3% in the last 24 hours to trade near $1.05, on volume of roughly $2.02 billion. Nothing in the data checked for this page confirms a single cause, and the move arrived alongside a broader rally across 15 top-100 coins.
Is SUI up for the week too, or just today?
Both, though most of the gain is recent. SUI is up about 43.3% over the past seven days, and the bulk of that climb happened in the final week rather than spreading evenly across it. Seven days before publication, SUI traded near $0.72.
Did Sui hit a new high today?
It set a new 90-day high near $1.05, based on CoinGecko's price history. Sui's all-time high (ATH) is still far off, at $5.35 on January 4, 2025, about 80.3% above where the token trades even after today's jump.
Does sending Sui get more expensive when the price jumps?
In dollar terms, yes. Sui pays its own network fee in SUI, and that fee amount in SUI has not changed today. What changed is how many dollars that same fee converts to, since SUI itself is worth about 28.3% more than it was yesterday.
Is Sui's trading volume today unusually high?
Yes. About $2.02 billion changed hands against a $4.30 billion market cap, a turnover of roughly 46.9%, well above what a typical session shows for a coin Sui's size.
What were Sui's price and trading volume during the move?
SUI traded near $1.05 at publication, up about 28.3% on the day, on 24-hour volume of roughly $2.02 billion against a market cap of about $4.30 billion. Those numbers move constantly, so a live source like CoinGecko will show a different figure by the time this is read.
