IOST price prediction: putting 1 yen and $1 to the test

Why we skip price targets

Short answer: nobody can tell you what IOST will be worth next year, and a single number tends to do more harm than good. Most “IOST price prediction” pages pick a figure, extend a line on a chart and call it a forecast. We would rather give you a tool you can reuse: the link between price, supply and market cap. Once you see how big IOST would have to become for a given price, you can judge any prediction on your own.

The calculator at the top of this page does that with live data. Type a target in yen or dollars and it multiplies it by the live circulating supply, then shows the market cap that target needs and how many times larger that is than the current one. It is a reality check, not a forecast. If you just want the price, the live IOST price page has the chart and history.

This page also covers the questions behind the searches: why IOST spiked in the past, why it so often fails to hold gains (the Japanese query “IOST 上がらない” is one of the most common), and how to think in scenarios instead of a target. None of it is investment advice.

The market-cap math

A coin’s market cap is its price multiplied by the number of tokens in circulation. Flip that around and any target price implies a market cap. CoinGecko and CoinMarketCap both put IOST’s circulating supply at roughly 36.7 billion. Treat that as an approximate, moving figure: their method isn’t published, and supply keeps growing as the IOST 3.0 issuance vests. The mainnet’s own token API shows about 32.6 billion IOST on the L1, and there is a separate BEP-20 supply on BNB Chain. We unpack these numbers on the IOST tokenomics page.

Here is the formula with a worked example. Price × circulating supply = market cap. So $0.01 × 36.7 billion = about $367 million. For yen targets the logic is the same: 1 yen × 36.7 billion = about 36.7 billion yen. To compare yen targets with dollar market caps, we use an illustrative rate of 150 yen per dollar in the table below. That rate is an assumption for the example, not a quote, and the yen moves. For your own conversions, the IOST converter uses live FX.

Two more details matter. First, the max supply is 90 billion IOST, so fully diluted value (price × max supply) is roughly 2.5 times the circulating market cap. Second, IOST’s market cap has sat in the tens of millions of dollars after a drawdown of more than 99% from the January 2018 high. That starting point is what every target has to be measured against.

Popular targets tested

These are the targets people actually type into search: 1 yen, 10 yen, 100 yen and 1,000 yen in Japanese, and $0.01, $0.1 and $1 in English. All implied caps use the same ~36.7 billion circulating supply. If supply rises, every one of these targets needs an even larger market cap.

1 yen and $0.01 are the only targets that IOST has traded at in recent memory. The December 2024 rally, driven by the IOST 3.0 announcement, peaked at about $0.0122, which was above 1 yen at the time. That doesn’t mean a return is easy. Since then, roughly 21.32 billion new IOST were created for the BNB Chain launch and keep vesting into the market, so the same price now needs a bigger market cap than it did then.

10 yen and $0.1 sit in mania territory. IOST was near those levels only twice: in January 2018, when its all-time high of $0.1298 came days after its first listing, and in the April 2021 run to about $0.0913 on Binance. Both happened during market-wide altcoin bubbles and with far fewer tokens in circulation.

100 yen, 1,000 yen and $1 fail the basic size test. A $1 IOST implies about $36.7 billion in market cap, and $90 billion fully diluted. Those are figures that only a handful of the largest blockchain networks have ever held, and they all have heavy daily usage. IOST’s Layer 2, by contrast, showed no user transactions in our research sampling across its whole history.

Why IOST pumped before

Looking at past spikes is more useful than any trend line, because it shows what actually moved the price. In almost every case the trigger was a market-wide wave or a piece of project news, and the gains faded once the news was priced in. The moves below come from Binance IOST/USDT data; the causes are the most likely drivers, not confirmed explanations.

1. Jan 2018All-time high of $0.1298Right after the first exchange listings, during the 2018 altcoin bubble.
2. Sep 2020Coincheck listingFirst Japanese exchange to list IOST (8 Sep 2020); the monthly high jumped.
3. Jan–Apr 2021About 16× in four monthsFrom roughly $0.0057 to $0.0913 in the 2021 bull run, with strong Japanese retail demand.
4. Nov–Dec 2024IOST 3.0 rally to ≈ $0.0122The PayFi vote and the BNB Chain Layer 2 announcement.
5. Sep 2026About 3× intraday, then a full retraceThe day after the 70M token burn announcement (8 Sep 2026).
6. Oct 2026Spike after the v4.0.0 noticeRoughly $0.00074 to $0.0019 on 20–21 Oct, back near the start by 23 Oct.

The two 2026 spikes are worth a closer look. On 9 September 2026 IOST roughly tripled within a day on heavy Binance volume, then gave it all back within days. On 20–21 October 2026, right after the mandatory v4.0.0 upgrade announcement, it more than doubled intraday and was back near its starting level two days later. Neither the burn nor the upgrade changed demand for IOST in any lasting way. Fast up, fast down, with volume concentrated in a short window, is the signature of pump-and-dump trading. Anyone chasing those candles mostly bought near the top. Between those spikes, IOST set its all-time low of $0.000526 on 19 August 2026.

What could push it up

A fair outlook needs the bullish case too, and IOST has a few real cards. None of them guarantees a higher price, but each is a thing you can track.

IOST 3.0, RWA and the BNB Chain Layer 2

The project rebuilt itself as IOST 3.0: an OP Stack Layer 2 on BNB Chain (chain ID 182) plus a BEP-20 IOST token, now pitched as infrastructure for real-world assets (RWA) and payments. In June 2025 it raised a $21 million strategic round led by DWF Labs, Presto and Rollman Management Group. If tokenized assets or payment apps actually land on the network and need IOST, that would be the first demand driver backed by usage rather than hype. Our IOST 3.0 guide explains what exists and what is still a plan.

A loyal Asian community and regulated listings

IOST’s base is unusually concentrated in Asia. The project’s CEO has called Japan its largest community and Korea its second-largest market. In Japan, four FSA-registered exchanges handle IOST and it sits on the JVCEA green list. In Korea, Upbit has traded IOST against the won since July 2018 and is one of the biggest IOST venues in the world. That retail base is why IOST tends to react so strongly to good news. See the IOST in Japan and IOST in South Korea pages for local detail.

Burns and an active L1

The foundation burned 70 million IOST from the legacy issuance in September 2026, and the protocol burns the 2% fee on RAM purchases. The IOST 3.0 docs also plan MEV burns and quarterly DAO-voted burns. Meanwhile the L1 keeps running with 0.5-second blocks, got the v4.0.0 upgrade and a new TypeScript SDK. Burns help only if they outpace issuance, and so far they have been small next to the 21.32 billion new tokens, but this is a lever to watch.

Want crypto ready before the next move?

CEX.IO, an exchange running since 2013, sells crypto such as BNB by card. It doesn’t list IOST, so the route is crypto first, then an exchange that lists IOST. It doesn’t serve Japan; Japanese residents should use an FSA-registered exchange such as Coincheck or OKJ.

What holds it back

The bearish list is longer, and it explains most of the chart since 2021. These are the factors we would weigh most heavily before trusting any IOST forecast.

Supply keeps expanding

IOST started with 21 billion tokens. The L1 supply is now about 32.6 billion, more than the stated 2% yearly issuance would produce, and the official docs contradict each other on inflation: one page says 2% a year, another describes annual halving. On top of that came the 21.32 billion IOST 3.0 issuance on BNB Chain, released over three to five years (the team share only after a one-year lock): 60% for validator rewards, 20% for airdrops and StakeDrops, the rest for community, grants, the DAO and the team. Every month, newly vested tokens look for buyers. The size of this issuance is why Upbit and the Korean exchange alliance DAXA issued a caution notice on 13 January 2025, and why price fell through early 2025.

Near-zero Layer 2 usage

The L2 is live, but our research found no user transactions in thousands of sampled blocks, and the sequencer has earned only about 0.25 BNB in fees over its lifetime. The L1 is quiet too: everyday throughput is a couple of transactions per second, mostly block rewards, and the official explorer counted only around a hundred active users in a 24-hour window. Roadmap targets such as more than $1 billion in RWA on-chain by the end of 2025 have not shown up. A token’s value story is hard to sustain when its network isn’t used.

Concentration and thin markets

The top 10 L1 accounts hold about 72% of the L1 supply, and the Upbit custody account dunamuiost alone holds roughly 30%. Most of those are exchange wallets, not single whales, but it shows how much of IOST sits with Korean retail on one platform. Japanese IOST/JPY order books are thin, and two Japanese exchanges, CoinTrade and BITPOINT, dropped IOST in the summer of 2026. Thin books make spikes easy and sustained rallies hard. Our IOST safety check covers these risks in full.

Why IOST 上がらない (why it won’t go up)

Japanese holders often search “IOST 上がらない” or “なぜ上がらない”: why doesn’t IOST go up? Pulling the threads together, the answer has four parts. First, supply overhang: vesting tokens from the IOST 3.0 issuance arrive every month, and each holder who sells absorbs buying pressure. Second, airdrop selling: the IOST 3.0 airdrop pays out in installments, monthly on Upbit and Bitkub and every six months on Coincheck and BitTrade, and some recipients sell what they receive. The IOST airdrop guide lists the schedules.

Third, no usage-driven demand. Gas on the IOST L2 is paid in BNB, not IOST, and the L2 is barely used, so the 3.0 upgrade has not created a natural buyer for the token yet. Fourth, rally sellers: after years of losses, many long-term holders treat any spike as a chance to exit, which is part of why the September and October 2026 jumps reversed so fast. None of this rules out a rally, but it explains why rallies have been short.

Waiting for 1 yen again…

Thinking in scenarios

Instead of one target, sketch three stories and watch which one the evidence supports. In a bear case, vesting continues, usage stays near zero and more exchanges trim listings or post caution notices. In that world the price keeps drifting and short spikes are selling opportunities for others. The 2026 delistings in Japan and the record low in August 2026 show this path is not hypothetical.

In a base case, IOST keeps its Asian listings and loyal holders, the L1 runs steadily and the 3.0 plans advance slowly. Price moves mostly with the wider altcoin market, with occasional news spikes. This roughly describes the last couple of years. In a bull case, real tokenized assets or payments show up on the network, burns become meaningful and a broad altcoin cycle lifts small caps. Even then, the honest ceiling is set by the market cap the tokens can support, which is why the table above matters.

What would move us from one scenario to another? Watch three things. On-chain activity: check transactions and accounts on the IOST explorer. Supply: track vesting and burns on the tokenomics page. Market access: watch whether exchanges such as Upbit and Coincheck keep IOST and its deposit networks open. If you decide to buy anyway, size it as money you can lose and use the IOST exchange list to pick a venue that fits your country.
